Asia’s $800 Billion Nuclear Splurge to Unlock Uranium Motherlode
http://www.bloomberg.com/news/articles/2015-05-07/asia-s-800-billion-nuclear-splurge-to-unlock-uranium-motherlode
A nuclear-power boom in Asia that’s set to drive up uranium prices is
triggering a resurgence in mining in Australia, home to the world’s
largest reserves.
Almost $800 billion
of new reactors are under development in the region, driven by China
and India where demand is climbing for the emission-free energy.
The value of uranium plunged in the wake of the 2011 Fukushima
nuclear disaster in Japan. Now, with contract prices forecast to jump
more than 60 percent, suppliers in Australia are planning about half a
dozen new mines.
“Australia is very well placed,” said Brian Reilly, managing director
of Canadian miner Cameco Corp.’s local unit, in a telephone interview.
“China and India will be very significant customers down the track.”
The mines on the drawing board in Australia, which holds a third of
the world’s known uranium reserves, include the Kintyre project, a joint
venture between Cameco and Mitsubishi Corp., that won government
approval last month.
China will need the equivalent of about 1,000 nuclear
reactors, 500,000 wind turbines or 50,000 solar farms as it steps up
its fight against climate change. The country in March approved
construction of its first nuclear power project since Fukushima brought
the program to a standstill.
Global Warming
India also views its push for new power plants as part of its effort to curb global warming. Cameco agreed last month to sell uranium from its Canadian mines to India.
Australia’s Prime Minister Tony Abbott last year signed an agreement
with India that opens the door for uranium sales and may help producers
such as BHP Billiton Ltd. and Rio Tinto Group-controlled Energy
Resources of Australia Ltd. Similar accords were signed last decade with
China and Russia.
Toro Energy Ltd. expects production at its Wiluna mine to start in
2017 or 2018, Chief Executive Officer Vanessa Guthrie said in an a phone
interview. The company has been seeking to bring in an Asian partner
and “in the last few months, the interest in Wiluna in particular, and
in the uranium market in general, has really started to increase,” she
said.
Cameco’s Yeelirrie mine and the Vimy Resources Ltd.-led Mulga Rock
project are also planned in Western Australia, which lifted a ban on
uranium mining in 2008. Exports from the four projects could exceed A$1
billion ($790 million) a year by the end of the decade if prices
recover, the state government estimated.
Exports Forecast
Exports from Australia are forecast to rise
at an average annual rate of 8 percent, according to government
estimates. The country supplies about 11 percent of global output and
has about 31 percent of the world’s reserves.
The expansion of new mines in Australia has been dogged in the past
by government prohibitions and opposition from environmentalists. The
Labor Party dropped its more than two-decade long ban on new uranium
mines in 2007, while leaving state governments with the power to reject
mining proposals.
While the nuclear-power boom in China and India bodes well, the
industry faces headwinds in the form of bulging inventories as the
planned mines in Australia wait for higher prices to kick in.
Both Cameco, which says price uncertainty makes it too hard to
estimate when Kintyre will begin, and Toro need long-term contract
prices to jump more than 35 percent from current levels of about $50 a
pound to make their projects viable. Contract prices are forecast to
rise to about $80 a pound in 2020, according to JPMorgan Chase & Co.
“When the market turns, we’ve seen this historically, it will
typically turn quickly and sharply, and we need to be ready,” said
Cameco’s Reilly.
Asia's projected $781 billion nuclear energy investment needs continuing international cooperation
World Nuclear Association Press Release: 15 January 2015
http://www.world-nuclear.org/Press-and-Events/Press-Statements/Asia-s-projected-%24781-billion-nuclear-energy-investment-needs-continuing-international-cooperation/
Continuing the strong cooperation between Chinese and international
nuclear companies will ensure that China can play its part in the global
nuclear supply chain.
WNA Director General Agneta Rising said:
"We must build on the international partnerships forged in
developing China's nuclear generation programme so that China can play
its part in delivering the global expansion of clean and reliable
nuclear energy the world so clearly needs."
Ms Rising was speaking at World Nuclear Spotlight 2015 conference, taking place in Beijing, China on 15 January 2015.

The potential market for the global nuclear supply chain is set out in The World Nuclear Supply Chain: Outlook 2030 report, which is launched today by the World Nuclear Association
The report's findings including:
1. Under a reference scenario that envisages the start-up of 266
new reactors, an investment of some $1.2 trillion would be required by
2030.
2. Taking into account nuclear power plant construction and
refurbishment projects for long-term operation the international market
for suppliers could be worth $30 billion per year.
3. The largest region of growth will be Asia - primarily China -
where 47 reactors are currently under construction and a further 142 are
forecast by 2030. Investment in nuclear projects in Asia could reach
$781 billion over the period.

China Climate Pledge Needs 1,000 Nuclear Plant Effort
Don't Miss Out —
Follow us on:
Nov. 21 (Bloomberg) -- China, which does nothing in small
doses, will need about 1,000 nuclear reactors, 500,000 wind
turbines or 50,000 solar farms as it takes up the fight against
climate change.
Chinese President Xi Jinping agreement last week with
President Barack Obama requires a radical environmental and
economic makeover. Xi’s commitment to cap carbon emissions by
2030 and turn to renewable sources for 20 percent of the
country’s energy comes with a price tag of $2 trillion.
The pledge would require China to produce either 67 times
more nuclear energy than the country is forecast to have at the
end of 2014, 30 times more solar or nine times more wind power.
That almost equals the non-fossil fuel energy of the entire U.S.
generating capacity today. China’s program holds the potential
of producing vast riches for nuclear, solar and wind companies
that get in on the action.
“China is in the midst of a period of transition, and that
calls for a revolution in energy production and consumption,
which will to a large extent depend on new energy,” Liang
Zhipeng, deputy director of the new energy and renewable energy
department under the National Energy Administration, said at a
conference in Wuxi outside of Shanghai this month. “Our
environment is facing pressure and we must develop clean
energy.”
‘Run its Course’
By last year, China had already become the world’s largest
producer of wind and solar power. Now, with an emerging middle
class increasingly outspoken about living in sooty cities
reminiscent of Europe’s industrial revolution, China is looking
at radical changes in how its economy operates.
“China knows that their model, which has done very well up
until recent times, has run its course and needs to shift, and
they have been talking about this at the highest levels,” said
Paul Joffe, senior foreign policy counsel at the Washington,
D.C.-based World Resources Institute.
Meeting the challenge is anything but assured. China has
already run into difficulty managing its renewables. About 11
percent of wind capacity sat unused last year because of grid
constraints, with the rate rising to more than 20 percent in the
northern provinces of Jilin and Gansu, according to the China
Renewable Energy Engineering Institute.
‘Chinese Dream’
With its huge population, China is a country accustomed to
eye-popping goals. Some have worked, such as the rapid growth
and poverty reduction from the market reforms of the past two
decades. Others, though, have exposed central planning run amok,
such as Mao Zedong’s Great Leap Forward in the 1950s to
collectivization and industrialization.
Xi sees no alternative to going big. “Letting children
live in a good ecological environment is a very important part
of the Chinese dream,” he said last week as he welcomed Asian
leaders to a summit in Beijing. His words aren’t just lip
service -- pressure is building.
Pollution Protests
Protests over pollution at least three times this summer
turned violent in Chinese cities. In Hangzhou, in the eastern
part of the country, rioters overturned cars and set fire to
police vehicles in May because of plans to build a waste
incinerator near a residential neighborhood.
In the weeks leading up to last week’s APEC summit, China
closed factories and limited traffic in Beijing so the air
wouldn’t be offensive to visiting dignitaries. In the capital,
141 enterprises were asked to cut production from Nov. 3 to Nov.
11, according to the Municipal Environmental Protection Bureau.
Xinhua News Agency said limits were placed on 3,900 plants in
Hebei province and 1,953 firms in Tianjin city.
A government previously focused on growth at all costs has
suddenly become sensitive to its environmental challenges,
activists say.
‘Social Discontent’
Smog in Beijing and Shanghai made the authorities “realize
that it has to take measures to rein in pollution, otherwise it
will cause social discontent,” said Li Shuo, a climate policy
researcher at Greenpeace East Asia. “Health is of immediate
concern to everyone.”
The targets Xi announced alongside Obama have been hailed
as a boost for negotiations at a United Nations conference
beginning Dec. 1 in Lima, Peru. Envoys from more than 190
nations are seeking to craft a global pact that world leaders
will sign next year in Paris.
The U.S. part of the deal includes a push to cut greenhouse
gas emissions to 26 to 28 percent below 2005 levels by 2025. The
current U.S. target is to reach a level of 17 percent below 2005
emissions by 2020. The Obama administration will likely have to
achieve these cuts largely through regulatory methods.
For China to succeed, it will have to install the clean
energy equivalent of Spain’s entire generating capacity each
year until 2030, according to Bloomberg New Energy Finance data.
It has achieved that only once -- last year.
‘Challenges Addressed’
“The fact is the Chinese government know they need to
clean things up,” Martijn Wilder, head of the global
environmental markets practice at law firm Baker & McKenzie,
said by phone from Sydney. “China is a developing country.
There are challenges, but those are rapidly being addressed.”
Electricity demand will rise 46 percent by 2020 and double
by 2030, according to the International Energy Agency. China
currently depends on coal for two-thirds of its energy, more
than any other Group of 20 country except South Africa.
The shift to renewables stands to benefit nuclear reactor
makers including General Electric Co. and Areva SA, along with
wind turbine manufacturers led by Xinjiang Goldwind Science &
Technology Co. and Vestas Wind Systems A/S. It also provides
expansion opportunities for China’s solar panel makers such as
Yingli Green Energy Holding Co. and Trina Solar Ltd., the two
biggest suppliers.
Energy Spending
“China, as one of the world’s biggest energy consumers,
must catch up as it lags behind other countries on energy
security and energy supply diversification,” said Chen
Kangping, chief executive officer of JinkoSolar Holding Co.,
China’s third-largest solar manufacturer.
In all, China will spend $4.6 trillion upgrading its power
industry by 2040. Nuclear and renewables alone will garner $1.77
trillion in new investment, taking 79 percent of all the funding
for power plants built in China, the IEA said in its World
Energy Outlook on Nov. 12. Fossil fuels get the remaining share.
The nuclear industry is under tighter scrutiny after the
Fukushima disaster and faces a manpower shortage. All those new
reactors will require large uranium supplies and as many as
1,000 workers each, Credit Suisse Group AG said.
Much of the change will come from a different economic mix,
said Joffe, of the World Resource Institute. China is already in
the midst of a long-term “rebalancing” of its economy,
shifting from a reliance on heavy industry to less energy-intensive service businesses, he said.

Modi Hails Indian Uranium-Supply Accord With Cameco
Don't Miss Out —
Follow us on:
The accord was announced Wednesday as Indian Prime Minister Narendra Modi visited Ottawa, the first such trip by a PM from that nation in a generation. Cameco stock rose the most in five months in Toronto.
India is the fastest growing market for nuclear power after China. The nation is extending electricity supplies to serve more of its 1.24 billion population. It operates 21 reactors; another six are being built and due to come online by 2017.
While nuclear power isn’t the cheapest option, it’s preferable from an environmental perspective, Modi said. “This is an effort to save the world from global warming and climate change,” Modi told reporters.
India’s Department of Atomic Energy will acquire 7.1 million pounds of uranium concentrate, Saskatoon, Saskatchewan-based Cameco said in a statement.
“This is a new port of entry, if you will, for Cameco’s uranium and we’re glad to have it open,” Chief Executive Officer Tim Gitzel said in a phone interview.
Cameco rose 5.7 percent to C$20.07 in Toronto, the highest close since Dec. 3.
Nuclear Fuel
“We haven’t done nuclear business with India for 40 years and to see that market open up, it’s great, not just for Cameco, but for India and Canada,” said Robert Gill, who helps manage about C$3.5 billion including Cameco shares at Lincluden Investment Management Ltd. in Oakville, Ontario.Modi said ahead of his trip that a nuclear-power accord was a priority. Canadians have a less positive outlook on supplying the fuel -- an Internet survey from the Angus Reid Institute published Tuesday showed 60 percent of respondents opposed helping develop India’s nuclear energy industry.
India already has uranium supply accords with Russia, Kazakhstan, France and Uzbekistan.
“The relatively modest supply agreement is, in our view, effectively a first step in potentially a more significant longer-term arrangement with India,” Greg Barnes, a Toronto-based analyst at TD Securities Inc., said in a note to clients.
Modi Seeks to Accelerate India-Australia Trade Pact Talks

Follow us on:
Nov. 18 (Bloomberg) -- Prime Minister Narendra Modi said he
wants to speed up negotiations on a comprehensive economic
partnership agreement with Australia as he seeks better access
for Indian businesses to the nation’s markets.
“This is a natural partnership arising from our shared
values, interests and strategic maritime location,” Modi told
reporters in Canberra today before addressing the Australian
Parliament.
Modi’s address comes a day after China and Australia
completed negotiations on a free-trade agreement and President
Xi Jinping told parliament he wants greater security ties with
Australia. China’s trade with Australia dwarfs that of India by
10 times and Prime Minister Tony Abbott said today he wants to
sign a trade accord with the South Asian nation by the end of
next year.
India is an “emerging, democratic superpower of Asia,”
Abbott told reporters. “The trade relationship is
underdeveloped and Prime Minister Modi and I have spent quite
some time this morning talking about what we need to do to
really crank up the trade relationship.”
Both India and Australia are seen by President Barack Obama
as important supporters of the U.S. pivot into the Asia-Pacific,
designed to counter China’s growing influence and territorial
claims in the region.
Uranium Sales
Abbott visited India in September and signed an agreement
for civil nuclear cooperation, opening the door for uranium
sales to the nation. During the visit, the nations agreed to
hold their first bilateral naval exercises in 2015.
“Security and defense are important and growing areas of
the new India-Australia partnership for our advancing regional
peace and stability,” Modi said today.
The nations agreed to extend defense cooperation to cover
research, development and industry engagement and hold
“regular” meetings of their defense ministers and military
staff, the leaders said in a joint statement.
Counter-terrorism cooperation will be enhanced to cover
transnational crimes including illegal migration.
Modi Masks
Last night, Modi addressed 21,000 people at Sydney’s
Olympic Park where he promised visas for Australian tourists
would soon be made available on arrival at Indian airports.
Supporters waved the nation’s tri-color flag and donned Modi
masks and T-shirts as they made their way into the arena.
His trip to Australia, where he attended the Group of 20
summit in Brisbane at the weekend, comes six months after his
landslide election win and is the first bilateral visit by an
Indian prime minister since 1986, according to his Twitter feed.
About 300,000 people born in India live in Australia,
according to the 2011 census. Relations between the two
countries have improved since 2009 when a wave of attacks on
Indian students studying in Melbourne, Australia’s second-biggest city, resulted in a drop in applications for student
visas.
India, which has an appetite for Australia’s coal, gold and
copper, is the nation’s 10th largest trading partner, accounting
for about A$15 billion ($13 billion) in exports and imports
including services, according to Australia’s Department of
Foreign Affairs and Trade.
Australia in December 2011 overturned a ban on uranium
exports to India initiated because the nation wasn’t a signatory
to the Nuclear Non-Proliferation Treaty. Exporting uranium to
India, which is seeking to curb power shortfalls crippling the
economy, will help Australian miners such as BHP Billiton Ltd.
and Rio Tinto Group-controlled Energy Resources of Australia
Ltd.

Australia's Uranium
(Updated April 2015)http://www.world-nuclear.org/info/Country-Profiles/Countries-A-F/Australia/
- Australia's uranium has been mined since 1954, and three mines are currently operating. More are planned.
- Australia's known uranium resources are the world's largest – 31% of the world total.
- In 2014 Australia produced 5897 tonnes of U3O8 (5000 tU). It is the world's third-ranking producer, behind Kazakhstan and Canada. All production is exported.
- Australia uses no nuclear power, but with high reliance on coal any likely carbon constraints on electricity generation will make it a strong possibility.
- In 2015 the South Australian government set up a royal commission into the potential for nuclear power.

- Appendix: A brief history of Australian uranium mining
The Australian economy is unique in the OECD in that about 20% of GDP
is accounted for by mining and mining services (in 2012). Uranium is a
small part of this economically, but in energy terms, uranium (3944 PJ
in 2012-13) comprises one-quarter of energy exports.
In the 1930s ores were mined at Radium Hill and Mount Painter in SA
to recover radium for medical purposes. As a result a few hundred
kilograms of uranium were also produced.
Uranium ores as such were mined and treated in Australia initially from the 1950s until 1971. Radium Hill, SA, Rum Jungle, NT, and Mary Kathleen,
Queensland, were the largest producers of uranium (as yellowcake).
Production ceased either when ore reserves were exhausted or contracts
were filled. Sales were to supply material primarily intended for USA
and UK weapons programs at that time. However, much of it was used for
electricity production.
The development of civil nuclear power stimulated a second wave of
exploration activity in the late 1960s. A total of some 60 uranium
deposits were identified from the 1950s through to the late 1970s, many
by big companies with big budgets. (Since then only two significant new
ones have been found: Kintyre and Beverley Four Mile. The minor
exploration boom 2002-07 was driven by small companies focused on
proving up known deposits.)
Mary Kathleen began recommissioning its mine and mill in 1974. Other
developments were deferred pending the findings of the Ranger Uranium
Environmental Inquiry, and its decision in the light of these. Mary
Kathleen's second production phase was1976 to the end of 1982.
The Commonwealth Government announced in 1977 that new uranium mining
was to proceed, commencing with the Ranger project in the Northern
Territory. This mine opened in 1981. In 1979, Queensland Mines opened Nabarlek
in the same region of Northern Territory. The orebody was mined out in
one dry season and the ore stockpiled for treatment from 1980. The mine
site is now rehabilitated.
A brief history of Australian uranium mining is appended. See also Former Australian Uranium Mines appendix.

Operating mines
The Ranger mine
and associated town of Jabiru is about 230 kilometres east of Darwin,
in the Northern Territory, surrounded by the Kakadu National Park, a
major tourist attraction. The mine opened in 1981 at a production rate
of approximately 3300 tonnes per year of uranium oxide and has since
been expanded to 5500 t/yr capacity. Mining of the second pit was 1997
to 2012, and this is now being backfilled. Treatment is conventional
acid leach. Future development will be underground, and application was
made for approval of this in January 2013. A final decision of whether
to mine the Ranger Deeps is expected at the end of 2014. Ranger is owned
by Energy Resources of Australia Ltd (ERA), a 68.39% subsidiary of Rio
Tinto.
During 1988 the Olympic Dam project,
then a joint venture of Western Mining Corporation and BP Minerals,
commenced operations about 560 km north of Adelaide, in an arid part of
South Australia. The massive deposit is underground, some 350 metres
below the surface, and is the largest known uranium orebody in the
world. The large underground mine produces copper, with gold and uranium
as major by-products. Annual production capacity for uranium oxide has
been expanded from 1800 to 4600 tonnes U3O8.
It is now owned by BHP Billiton, following its 2005 takeover of WMC
Resources. There are plans to greatly increase the mine's size and
output, by accessing the orebody with a huge open pit, about 4.1 x 3.5
km and 1000m deep. (Further details below)
About 80% of the uranium is recovered in conventional acid leach of
the flotation tailings from copper recovery. Most of the remaining 20%
is from acid leach of the copper concentrate, but that concentrate then
still contains up to 0.15% uranium. Hence the copper must be smelted at
site, since selling it to overseas smelters would create both processing
and safeguards complications for the smelter operator. This could
change as part of a major envisaged expansion.
Both Ranger and the now-closed and rehabilitated Nabarlek mines are
on aboriginal land in the Alligator Rivers region of the Northern
Territory. Aboriginal people receive royalties of 4.25% on sales of
uranium from Northern Territory mines. The total received simply from
Ranger is now over $207 million, and $14 million came from Nabarlek.
The Olympic Dam mine is on formerly pastoral land in the middle of
South Australia. A town to accommodate 3500 people was built at Roxby
Downs to service the mine. The 18,000 ha mine lease is managed as a
nature reserve.
The small Beverley mine
in South Australia started operation late in 2000, 520 kilometres north
of Adelaide, on the plains north-west of Lake Frome. It was Australia's
first in situ leach (ISL) mine, accessing a palaeochannel deposit in
sand in a saline aquifer. It was licensed to produce 1180 t/yr U3O8
(1000 tU), and reached this level in 2004, though production has
declined since. It is owned and operated by Heathgate Resources Pty Ltd,
an associate of General Atomics in the USA. In December 2010 the
company received government approval to mine the Beverley North
deposits, and in the last two years of operation almost all production
through the Beverley plant came from this north orebody which is
contiguous with the Four Mile deposits. Mining of Beverley ceased at the
end of 2013, and of Beverley North early in 2014.
The Four Mile leases are contiguous with Beverley, and mining the
east orebody by ISL commenced in April 2014. Resources are split between
the west and the east orebodies, and the northeast orebody is also
prospective. Uranium recovery is through Heathgate’s Pannikin satellite
ion exchange plant then trucking the loaded resin to the main Beverley
plant for stripping (elution) and precipitation, as is done at two US
mines. Alliance Resources Ltd is a 25% free-carried joint venture
partner after Heathgate's Quasar subsidiary farmed into the project.
Production is at about 1200 t U3O8 per year.
The Honeymoon
ISL mine in South Australia commenced operation in 2011. The owners
received government approval to proceed with ISL mine development in
November 2001 but reassessed its ore reserves and Uranium One, based in
Toronto, finally moved to development in 2007. In 2008 Mitsui agreed to
join the project as 49% joint venture partner, and a construction
contract was then let. Operations were ramping up to 400 t/yr. In 2012
production was expected to be 275 tonnes U3O8,
at $47/lb – three times the average cost of production in Kazakhstan.
In fact it produced less. Mitsui largely funded the development and
commissioning, but then withdrew from the project in 2012. In November
2013 Uranium One closed the mine and put it on care and maintenance
until uranium prices improved.

Prospective mines and expansion
The Jabiluka
uranium deposit in the Northern Territory was discovered in 1971-73, 20
kilometres north of Ranger. It is surrounded by the Kakadu National
Park, but the mine lease area is excluded from the National Park and
adjoins the Ranger lease. It has resources of over 130 000 tonnes of
uranium oxide, and is one of the world's larger high-grade uranium
deposits. A mining lease was granted in 1982 but development was stalled
due to disagreements with the Aboriginal traditional owners. Then with
the Australian Labor Party coming to power in the 1983 federal election,
Commonwealth approval was withdrawn and development ceased. In 1991
Energy Resources of Australia (ERA), the operator of the adjacent Ranger
mine, bought the Jabiluka lease from Pancontinental for A $125
million.
Following the 1996 change of government and further approvals,
development of the underground mine proceeded with an 1150 metre access
decline and a further 700 metres of excavation around the orebody.
However, mining was deferred until agreement could be reached regarding
treatment of Jabiluka ore at the Ranger mill. ERA (whose parent company
is Rio Tinto) will not proceed with the mine until there is agreement
from the local Mirrar Aboriginal people.
For Olympic Dam BHP
Billiton undertook a major feasibility study on greatly expanding the
mine, and in 2009 it released the 4600-page environmental impact
statement for the project. This was approved by state and federal
governments in October 2011. The plan is to develop a large open pit
with associated infrastructure over 11 years and lift uranium production
to 19,000 tonnes U3O8
per year. The open pit would mean that up to 98% of the ore is mined
rather than 25% of it. Most of the uranium would be separated at the
mine, but up to 2000 t/yr would be exported in copper concentrates,
requiring a smelter for these in China or Japan which is subject to
safeguards. New infrastructure would include a 280 ML/day desalination
plant on Spencer Gulf, supplying 200 ML/day to the operation, and 650
MWe increase in power supply. The present underground mining would
continue in the narrow northern part of the orebody. However, in August
2012 the company said that it would investigate a new and less-costly
design for its planned open-pit expansion, which meant it could not
approve the project in time to meet a government deadline in December.
In November 2012 the state government granted a four-year extension,
conditional on the company spending $650 million on pre-project research
on heap leaching and on community work.
In November 2014, in a general announcement about productivity, BHP
Billiton flagged a 27% increase in copper production at Olympic Dam from
2018, and a doubling from that level subsequently by “a low-risk
underground expansion with significantly lower capital intensity than
the previous open cut design. This has the potential to deliver over
450,000 tonnes of copper production a year at first quartile C1 costs by
the middle of next decade”. The uranium implications were not
mentioned, but assuming the same ore as today, it would mean about 5000 t
U3O8 (4200 tU) per year from 2018 and some 9400 t U3O8 (8000 tU) per year in mid-2020s.
Cameco and Mitsubishi (70:30%) bought the Kintyre deposit
in WA in 2008 from Rio Tinto for uS$ 495 million. Cameco initially
envisaged starting mine construction in 2013 and operation in 2015, to
produce 2700 to 3600 t U3O8 per year for 15 years. In mid-2012 Cameco put the project on hold pending firmer uranium prices or lower development costs.
BHP Billiton applied to bring its Yeelirrie, WA, deposit into production and projected 2000 t/yr U3O8 production
from 2014, though in February 2010 approval was sought for production
at 3500 t/yr. However, in 2011 the project was wound down due to high
treatment costs and in 2012 it was sold to Cameco for US$ 340 million.
In November 2014 Cameco requested the WA EPA to cancel the earlier
environmental application, and submit a new one involving production at
7500 t U3O8 per year, and to assess the application under new 2012 EPA procedures.
Toro Energy is well advanced with plans to produce 750 t/yr U3O8 from its Wiluna
project, comprising the shallow Lake Way and Centipede-Millipede
deposits and the nearby Lake Maitland deposit in WA, from 2016.
Energy & Minerals Australia is developing the Mulga Rock deposits in WA, with ISL production targeted for 2014, and that from lignite in 2016.
The largest prospective Queensland mine is Paladin's Valhalla, 40 km north of Mount Isa. This is a major deposit but was stalled to 2012 by state government policies.
UraniumSA Ltd has its Samphire project south of
Whyalla on the Eyre Peninsula. Both main orebodies are amenable to ISL
mining, though the aquifers are very saline. In 2011 further
mineralisation, some high-grade, was identified in or on the granite
basement opening up the prospect of open pit mining.
There has been increasing foreign equity in Australian uranium
deposits. As well as the Honeymoon, Kintyre and Yeelirrie projects
above, in February 2009 Mega Uranium sold 35% of the Lake Maitland
project to the Itochu Corporation (10% of Japanese share) and Japan
Australia Uranium Resources Development Co. Ltd. (JAURD), acting on
behalf of Kansai Electric Power Company (50%), Kyushu Electric Power
Company (25%) and Shikoku Electric Power Company (15%) for US$ 49
million. In 2006 Sinosteel bought 60% of Pepinini's Curnamona project
for A$ 31 million, and in 2009 China Guangdong NPC bought 70% of Energy
Metals' Bigrlyi project for A$ 83.6 million. Both are early-stage
exploration ventures.
For more detail of mine prospects see paper: Australia's Uranium Deposits and Prospective Mines.
Economic benefits of mining uranium
About 1200 people are employed in uranium mining, at least 500 in
uranium exploration, and 60 jobs are in regulation of uranium mining.
Uranium mines generate about A$ 21 million in royalties each year (in
2005: Ranger $13.1 million, Beverley $1.0 million and Olympic Dam $6.9
million attributable to uranium). Corporate taxes amount to over $42
million per year.
Uranium exports from Australia
Australian production is all exported, and over the six years has averaged over 8600 t/yr U3O8,
and in 2012 provided 12% of world uranium supply from mines. Uranium
comprises about 35% of the country's energy exports (4150 PJ av) in
thermal terms.
Australia's uranium is sold strictly for electrical power generation only, and safeguards are
in place to ensure this. Australia is a party to the Nuclear
Non-Proliferation Treaty (NPT) as a non-nuclear weapons state. Its
safeguards agreement under the NPT came into force in 1974 and it was
the first country in the world to bring into force the Additional
Protocol in relation to this – in 1997. In addition to these
international arrangements Australia requires customer countries to have
entered a bilateral safeguards treaty which is more rigorous than NPT
arrangements.
The value of Australia's uranium oxide concentrate exports is
considerable, and in 2009 they reached a value of over A$ 1.1 billion.
However, production problems at Olympic Dam from late 2009 into 2010 set
production back considerably over those two years, then the Fukushima accident in March 2011 softened prices.
In 2013, U3O8 sales were to North America
(mainly USA) 2201 t (33.6%), Europe 2480 t (37.8%) and Asia 1873 t
(28.6%). (These figures are deliveries of Australian product to
customers’ converter accounts and exclude third party material purchased
to fulfill contract obligations.)
The nations which currently purchase Australia's uranium are set out
below, though up to date details on country destinations is not
available. All have a large commitment to nuclear power:
The USA generates around 30% of the world's nuclear power. Much of
its uranium comes from Canada, but Australia is a major source. Europe
depends heavily on nuclear power and EU countries are also major
customers. Japan, South Korea and now China are important customers due
to their increasing dependence on nuclear energy.
Customer countries' contracted imports of Australian uranium oxide
concentrate may be summarised as follows, though detailed information
has not been readily available in recent years: (see also the reactor table):
- USA: up to 5000 tonnes per year (the apparent level in 2013).
- EU: up to 3500 tonnes per year, including Belgium, Finland, France, Germany, Spain, Sweden, UK. Apparently about 2300 t in 2013.
- Japan: up to 2500 tonnes per year.
- South Korea: up to 1500 tonnes per year.
- China: about 500 tonnes per year.
- Taiwan: up to 500 tonnes per year.
- Canada and South Africa: both are uranium producer countries with nuclear power plants and which buy a small amount from Australia occasionally.
Australia is a preferred uranium supplier to world, especially East
Asian, markets where demand is growing most rapidly. In 2006 a bilateral
agreement was concluded with China, enabling exports there, and in 2007
a similar agreement was signed with Russia, which came into force in
2010. An agreement with the United Arab Emirates (UAE) came into force
in 2014, making the total 22 (covering 47 countries) and another with
India is being negotiated. Australia could readily increase its share of
the world market because of its low cost resources and its political
and economic stability.
As well as uranium sold to overseas customers (mainly utilities) by
the four mining companies, Energy Metals Ltd, an exploration company
with majority Chinese ownership, has an export permit. In December 2011
it announced the sale of 68 tonnes of U3O8 to
its parent company, China General Nuclear Power, for shipment in 2012.
(CGN’s wholly-owned subsidiary, China Uranium Development Co., is Energy
Metals’ largest shareholder with a 60.6% stake. The company sources
uranium from Australian producers.)
Environmental aspects of uranium exports are notable: Shipping 7000 tonnes of U3O8 as
in 2010 is the energy equivalent of shipping 140 million tonnes of
thermal coal. Australia's present thermal coal exports are over 100
million tonnes, requiring between 3,000 and 4,000 voyages of bulk
carriers through environmentally sensitive regions such as the Great
Barrier Reef. Export coal also has an environmental impact through the
provision of harbours and railways.
Uranium resources
On the basis of December 2012 data Australia has 29% of the world's
uranium resources (under US$ 130/kg) – 1.7 million tonnes of uranium.
Almost half of Australia's 1.174 million tonnes of Reasonably Assured
Resources of uranium in this price category were actually in the under
$80/kg U category when this was last reported.
The world’s Reasonably Assured plus Inferred Resources in the $130/kg category are tabulated in the Supply of Uranium information paper.
A review of Australia’s uranium is provided in Australia’s Uranium: Resources, Geology and Development of Deposits.
The vast majority of Australia's uranium resources to $130/kgU) are
within five deposits: Olympic Dam (the world's largest known uranium
deposit), Ranger, Jabiluka, Kintyre and Yeelirrie.
Despite restrictive state government policies and perhaps in
anticipation of their disappearance, uranium exploration gathered pace
during 2006, with more than 200 companies professing an interest,
compared with 34 the previous year, and A$ 80 million being spent.
Expenditure then more than doubled, to A$ 182 million in 2007, A$ 227
million in 2008, A$ 180 million in 2009 and A$ 190 million in 2011. It
then declined abruptly to A$ 98 million in 2012.
Uranium exploration has been illegal in Victoria and New South Wales,
and remains so in Victoria. Uranium mining is being reinstated in
Queensland after a few years break.
Nuclear power prospects in Australia
Australia has a significant infrastructure to support any future
nuclear power program. As well as the Australian Nuclear Science &
Technology Organisation (ANSTO), which owns and runs the modern 20 MWt
Opal research reactor, there is a world-ranking safeguards set-up – the
Australian Safeguards & Non-proliferation Office (ASNO), the
Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) and a
well-developed uranium mining industry.
However, in contrast to most G20 countries, the main driver for
nuclear power in Australia is reduction of CO2 emissions, or costs
arising from that. Apart from that, Australia's huge coal resources and
significant natural gas underwrite energy security and provide low-cost
power.
There are several legal hurdles impeding consideration of nuclear
power for Australia. NSW has a Uranium Mining and Nuclear Facilities
(Prohibition) Act 1986, and Victoria has a Nuclear Activities
(Prohibitions) Act 1983. Federally, the Environment Protection and
Biodiversity Conservation Act 1999 and Australian Radiation Protection
and Nuclear Safety Act 1988 will need to be amended to remove
prohibitions against effective regulation of nuclear power.*
*The ARPANS Act 1998 has section 10 Prohibition on certain nuclear installations, and the EPBC Act 1999 much the same in section 140A. ARPANS Act section 10:
- Nothing in this Act is to be taken to authorise the construction or operation of any of the following nuclear installations:
- (a) a nuclear fuel fabrication plant;
- (b) a nuclear power plant;
- (c) an enrichment plant;
- (d) a reprocessing facility.
- The CEO must not issue a licence under section 32 in respect of any of the facilities mentioned in subsection (1).
Fuller details and context are on the Decarbonise SA website.
UMPNER report 2006 and follow-on
In December 2006 the report of the Prime Minster's expert taskforce
considering nuclear power was released. It said nuclear power would be
20-50% more expensive than coal-fired power and (with renewables) it
would only be competitive if "low to moderate" costs are imposed on
carbon emissions (A$ 15-40 – US$ 12-30 – per tonne CO2). "Nuclear power
is the least-cost low-emission technology that can provide base-load
power" and has low life cycle impacts environmentally.
The then Prime Minister said that in the context of meeting increased
energy needs while reducing greenhouse gas emissions "if we are to have
a sensible response we have to include nuclear power". "The report
provides a thorough examination of all aspects of the nuclear fuel cycle
and the possible role of nuclear power in generating electricity in
Australia in the longer term. It provides a clear and comprehensive
analysis of the facts surrounding the nuclear industry and debunks a
number of myths. I am certain that the report will make a significant
contribution to informing public debate on these issues."
The report said that the first nuclear plants could be running in 15
years, and looking beyond that, 25 reactors at coastal sites might be
supplying one-third of Australia's (doubled) electricity demand by 2050.
Certainly "the challenge to contain and reduce greenhouse gas emissions
would be considerably eased by investment in nuclear plants." "Emission
reductions from nuclear power could reach 8 to 18% of national
emissions in 2050".
In April 2007 the Prime Minister announced that the government would
proceed to open the way for nuclear power in Australia by setting up a
nuclear regulatory regime and removing any regulatory obstacles which
might unreasonably stand in the way of building nuclear power plants.
Australia would also apply to join the Generation IV International
Forum, which is developing advanced reactor designs for deployment about
2025. The government would also take steps to remove impediments to
uranium mining. "Policies or political platforms that seek to constrain
the development of a safe and reliable Australian uranium industry – and
which rule out the possibility of climate-friendly nuclear energy – are
not really serious about addressing climate change in a practical way
that does not strangle the Australian economy."
In June 2007 the emissions trading taskforce report proposed that
Australia should move steadily to implement an emissions trading scheme
by 2012. While Australia cannot afford to wait upon a global regime, its
own should be devised so as to avoid the shortcomings of present
schemes and also articulate internationally. Both emission reduction
targets and carbon price would be low initially and ramp up. The need
for a trading scheme "more comprehensive, more rigorously grounded in
economics and with better governance than anything in Europe" was noted.
It would be designed to appeal to developing nations. The cost
increment on coal-fired power generation brought about by a carbon
emission cost would be likely to make nuclear power competitive in
Australia.
With a change of government late in 2007 the move towards nuclear
power was halted and the implementation of an emissions trading scheme
became bogged down in political rhetoric.
National Generators Forum 2006
Any proposal for building nuclear power plants would need to be
brought forward by generating companies. The National Generators Forum
published a report in 2006 on Reducing Greenhouse Gas Emissions from Power Generation
which concluded that "Stabilising emissions at present levels and
meeting base-load requirements could be achieved with nuclear power at
comparatively modest cost." While projected cost increases to 2050 could
be more than 120%, using nuclear power would halve the increase. "At
$20 per tonne of CO2 price, nuclear starts to become more cost-effective
than current fossil fuel technologies."
Cooling will be a major issue in respect to future base-load
generating capacity in Australia. At present about 80% of electricity is
produced from coal-fired plants, mostly cooled by evaporating water in
cooling towers. An estimated 400 GL/yr of fresh water is thus evaporated
and lost - about the same as Melbourne's water use. In the light of
widespread shortage of fresh water, cooling of nuclear plants would need
to be by seawater, hence coastal sites would be required* and to the
extent that nuclear plants actually replaced coal-fired plants, a very
large amount of fresh water would be freed up for other uses. Coastal
location of nuclear plants would also give rise to the possibility of
cogeneration, using waste heat or surplus heat for desalination and
production of potable water.
* A coal plant is normally sited on a coalfield
(inland), so does use a lot of water for evaporative cooling towers. A
nuclear plant can be anywhere, from the point of view of fuel supply.
IFNEC participation
In September 2007 Australia was one of eleven countries joining the
five founders in the Global Nuclear Energy Partnership (now the
International Framework for Nuclear Energy Cooperation – IFNEC).
Australia made it a condition that it is not obliged to accept any
foreign nuclear wastes, and it reserved the right to enrich uranium in
the future. In the lead up to this Australia and the USA finalized a
joint action plan for civil nuclear energy cooperation including R&D
and regulatory issues.
ATSE action plan 2014
In July 2013 the Australian Academy of Technological Sciences and
Engineering (ATSE) held a two-day conference on nuclear power for
Australia. This resulted in an action plan
in 2014, which included comparing the nuclear option with alternative
energy scenarios in the 2030-2050 timeframe, reviewing current policies
which preclude consideration of nuclear power, commence open and active
community engagement, building on overseas R&D program linkages.
SA royal commission 2015
In February 2015 the Labor state government of South Australia set up a royal commission
into the potential for nuclear power in that state, which already
produces two-thirds of Australia’s uranium. The terms of reference
include fuel cycle and high-level waste disposal as well as power
generation, and it is to report by May 2016. The inquiry is supported by
the state Liberal (conservative) opposition and the federal Liberal
coalition government, but not by the federal Labor party (though it
supports uranium mining). Assuming that the royal commission’s findings
are positive, the main question is: to what extent will they be accepted
nationally? Certainly before any nuclear capacity was built anywhere,
federal laws would need to be changed.
The first of four issues papers was published in April 2015. On
uranium exploration, ming and milling. Others will follow on: fuel
conversion, enrichment, fabrication and reprocessing; electricity
generation; and waste management. The due date for written submissions
is 24 July 2015.
Insofar as the royal commission will direct future power investment
in SA, the question of reactor unit size arises. At present the unit
size of any generating unit there is regulated at 260 MWe, though
modelling has shown 500 MWe units are possible. Small modular reactors
would therefore be indicated. But if transmission links were expanded a
SA nuclear power plant with large reactors could serve the eastern
states.
Earlier background to considering nuclear power
See also WNA's Appendix on Australian Research Reactors.
In 1953 the Australian Parliament passed the Atomic Energy Act, which
established the Australian Atomic Energy Commission (AAEC). AAEC's
functions included advising the Government on nuclear energy matters,
and the Commission quickly decided that effective and informed advice
could only be provided if there was underlying expertise directly
available to it. Hence in 1955 it established a research establishment
at Lucas Heights, near Sydney and began assembling a world class team of
scientists and engineers. It also began construction of a materials
testing reactor, HIFAR, which first achieved criticality and started up
on Australia Day, in January 1958.
The AAEC's research program was initially very ambitious and included
studies of two different power reactor systems, on the base of
substantial multi-disciplinary research in the fields of physics,
chemistry, materials science and engineering. Later, recognising
Australia's potential as a source of uranium, AAEC also undertook an
experimental research program in the enrichment of uranium.
The AAEC also initially convinced the Government that there would be
benefits from the construction of a "lead" nuclear power station on
Commonwealth land at Jervis Bay, south of Sydney. After competitive bids
were obtained, a reshuffle of leadership in the Government led to a
loss of interest in the proposal and the project was eventually
abandoned in 1972.
In the late 1950s nuclear power was considered for the large new
power station at Port Augusta in SA, which was eventually commissioned
in 1963 to burn very low-grade coal from Leigh Creek. In the late 1960s
Victoria's State Electricity Commission undertook preliminary studies on
building a large nuclear plant on French Island in Westernport. In 1969
the South Australian government proposed a nuclear power plant in SA to
supply the eastern states' grid. Then in 1976 the SA government in its
submission to the Ranger Uranium Inquiry said nuclear power appeared
inevitable for SA, perhaps by 2000.
In 1981, the government's National Energy Advisory Committee
presented a report on the administrative and legal issues associated
with any domestic nuclear power program. It recommended that "the
commonwealth, state and Northern Territory governments should develop
with minimum delay a legal framework using complementary legislation as
appropriate for licensing and regulating health, safety and
environmental and third party liability aspects."
In Australia the possibility of nuclear power is hindered in Victoria
and NSW, by legislation enacted by previous governments. In Victoria
the Nuclear Activities (Prohibitions) Act 1983 prohibits the
construction or operation of any nuclear reactor, and consequential
amendments to other Acts reinforce this. In NSW the Uranium Mining and
Nuclear Facilities (Prohibitions) Act 1986 is similar. In 2007 the
Queensland government enacted the Nuclear Facilities Prohibition Act
2006, which is similar (but allows uranium mining).
Electricity options
Coal provides the majority of Australia's electricity, and the full picture is given in the paper Australia's Electricity,
as an Appendix to this. This also accounts for most of the 200 Mt/yr
carbon dioxide emissions from electricity and heat production and uses
up about 400 GL/yr of fresh water for evaporative cooling. Preliminary
IEA figures show 2013 generation of 247 TWh, 64% from coal and 20.5%
from gas
Australia is fortunate in having large easily-mined deposits of coal
close to the major urban centres in the eastern mainland states. It has
been possible to site the major power stations close to those coal
deposits and thus eliminate much of the cost and inconvenience of moving
large tonnages of a bulky material. Energy losses in electricity
transmission are relatively low.
Western and South Australia have relatively less coal but plenty of
gas and also lower demand for electricity. More than half of their
electricity is derived from burning gas. Development of Tasmania's large
hydro-electric resources has put off the day when it needs any large
thermal power stations, but hydro potential is now almost fully
utilised.
In the next 15 years or so Australia is likely to need to replace the
oldest quarter of its thermal generating capacity, simply due to old
age. This is at least 8000 MWe, practically all coal-fired. If it were
replaced by gas-fired plant, there would be a reduction of about 25-30
million tonnes of CO2 emissions per year. If it were replaced by say six
nuclear reactors there would be a reduction of about 50 million tonnes
of CO2 emissions per year. Every 22 tonnes of uranium (26 t U3O8) used
saves the emission of one million tonnes of CO2 relative to coal.
In other parts of the world as well as Western and South Australia,
there was a conspicuous "flight to gas" in the late 1990s while gas
prices were low. Generating plant to utilise gas is relatively cheap and
quickly built, and at the point of use, gas-fired electricity does
cause only half the greenhouse emission of coal. It is clearly an option
to utilise more gas for electricity in Australia if low gas prices can
be maintained many years ahead.
Moving to gas would be seen by some as a great step forward for the
environment. Others would see it as a tragic waste of a valuable and
versatile energy resource. Gas can be reticulated to homes and factories
to be burned there at much greater efficiency overall.
In January 2007 the Energy Supply Association of Australia (ESAA)
completed a study on electricity supply options relative to CO2 emission
constraints in meeting projected load in 2030. For a 67% increase in
electricity load, greenhouse gas emission targets of 140%, 100% and 70%
of 2000 levels were modeled, with three supply options: all credible
technologies; without nuclear; and without both nuclear and fossil fuel
(with carbon capture and storage). Constraining CO2 emissions would
require nuclear contributing 20% of the power, with overall about 30%
increase in costs, hence a need for costing carbon to cover this. ESAA
concluded that "the widest possible range of generation technologies
will be needed."
Radioactive wastes
While Australia has no nuclear power producing electricity, it does
have well-developed usage of radioisotopes in medicine, research and
industry. Many of these isotopes are produced in the research reactor at
Lucas Heights, near Sydney, then used at hospitals, industrial sites
and laboratories around the country.
Each year Australia produces about 45 cubic metres of radioactive
wastes arising from these uses and from the manufacture of the isotopes –
about 40 m3 low-level wastes (LLW) and 5 m3 intermediate-level wastes
(ILW). These wastes are now stored at over a hundred sites around
Australia. This is not considered a suitable long-term strategy.
Since the late 1970s there has been an evolving process of site
selection for a national radioactive waste repository for LLW and
short-lived ILW. There has also been consideration of the need to locate
a secure storage facility for long-lived intermediate-level wastes
including those which will be returned to Australia following the
reprocessing of used fuel from Lucas Heights. Eventually, disposal
options for this will need to be considered also.
Low-level wastes and short-lived intermediate-level wastes will be
disposed of in a shallow, engineered repository designed to ensure that
radioactive material is contained and allowed to decay safely to
background levels. Dry conditions will allow a simpler structure than
some overseas repositories. The material will be buried in drums or
contained in concrete. The repository will have a secure multi-layer
cover at least 5 metres thick, so that it does not add to local
background radiation levels at the site.
There is a total of about 3700 cubic metres of low-level waste
awaiting proper disposal, though annual arisings are small (the 40 cubic
metres would be three truckloads). Over half of the present material is
lightly-contaminated soil from CSIRO mineral processing research
decades ago (and could conceivably be reclassified, since it is no more
radioactive than many natural rocks and sands).
Long-lived intermediate-level (category S) wastes will be stored
above ground in an engineered facility designed to hold them secure for
an extended period and to shield their radiation until a geological
repository is eventually justified and established, or alternative
arrangements made.
There is about 500 cubic metres of category S waste at various
locations awaiting disposal, and future annual arisings will be about 5
cubic metres from all sources including states & territories,
Commonwealth agencies and from radiopharmaceutical production, plus the
returned material from reprocessing spent ANSTO research reactor fuel in
Europe. This will be conditioned by vitrification or embedding in
cement, and some 26 cubic metres of it is expected by about 2020.
In March 2012 parliament passed the National Radioactive Waste
Management Bill 2010 which provides for a national repository for
low-level wastes and store for intermediate-level wastes, on land which
has been volunteered by its owners, probably at Muckaty Station in the
Northern Territory.

Research & development, isotope production
The High Flux Australian Reactor (HIFAR) operated at Lucas Heights
near Sydney from 1958 to 2007, and was for many years the only operating
nuclear reactor in Australia. It was used for materials research, to
produce radioactive materials for medicine and industry and to irradiate
silicon for the high performance computer industry. It was a 10 MW unit
which had the highest level of availability of any research reactor in
the world. It was at the heart of almost all the research activities of
the Australian Nuclear Science and Technology Organisation (ANSTO) and
supported those of several other organisations on the same site.
In 2006 HIFAR was replaced by a new research reactor, known as OPAL
(Open Pool Australian Light-water reactor), a modern 20 MW neutron
source. It achieves over 300 operational days per year, in the top
league of the world's 240 research reactors. OPAL uses low-enriched fuel
and for Mo-99 production it irradiates low-enriched targets which are
then processed to recover the Mo-99.
In September 2012 ANSTO announced a A$ 168 million expansion of its
Sydney facilities, principally for molybdenum-99 production, the source
of technetium-99 which is widely used in nuclear medicine for diagnosis.
Current world demand is about 45 million doses (23,000 six-day TBq/yr)
per year, and the new plant will be capable of meeting about one quarter
of this from 2016 at a time when the main plants in Canada and Europe
are set to close. The new plant will more fully utilise the OPAL
reactor. The investment also covers building a plant for Synroc
wasteform.

Appendix
A brief history of Australian uranium mining
The existence of uranium deposits in Australia has been known since
the 1890s. Some uranium ores were mined in the 1930s at Radium Hill and
Mount Painter, South Australia, to recover minute amounts of radium for
medical purposes. Some uranium was also recovered and used as a bright
yellow pigment in glass and ceramics.
Following requests from the British and United States governments,
systematic exploration for uranium began in 1944. In 1948 the
Commonwealth Government offered tax-free rewards for the discovery of
uranium orebodies. As a result, uranium was discovered by prospectors at
Rum Jungle in 1949, and in the South Alligator River region (1953) of
the Northern Territory, then at Mary Kathleen (1954) and Westmoreland
(1956) in north west Queensland.
In 1952 a decision was taken to mine Rum Jungle, NT and it opened in 1954 as a Commonwealth Government enterprise. Radium Hill, SA was reopened in 1954 as a uranium mine. Mining began at Mary Kathleen, Qld in 1958 and in the South Alligator region,
NT in 1959. Production at most mines ceased by 1964 and Rum Jungle
closed in 1971, either when ore reserves were exhausted or contracts
were filled. Sales of some 7730 tonnes of uranium from these operations
were to supply material primarily intended for USA and UK weapons
programs at that time. However much of it was used in civil power
production.
The development of nuclear power stimulated a second wave of
exploration activity in the late 1960s. In the Northern Territory,
Ranger was discovered in 1969, Nabarlek and Koongarra in 1970, and
Jabiluka in 1971. New sales contracts (for electric power generation)
were made by Mary Kathleen Uranium Ltd., Queensland Mines Ltd. (for
Nabarlek), and Ranger Uranium Mines Pty. Ltd., in the years 1970-72.
Successive governments (both Liberal Coalition and Labor) approved these, and Mary Kathleen began
recommissioning its mine and mill in 1974. Consideration by the
Commonwealth Government of additional sales contracts was deferred
pending the findings of the Ranger Uranium Environmental Inquiry, and
its decision in the light of these. Mary Kathleen recommenced production
of uranium oxide in 1976, after the Commonwealth Government had taken
up a 42% share of the company.
The Commonwealth Government announced in 1977 that new uranium mining was to proceed, commencing with the Ranger project
in the Northern Territory. In 1979 it decided to sell its interest in
Ranger, and as a result Energy Resources of Australia Ltd was set up to
own and operate the mine. The mine opened in 1981, producing 2800 t/yr
of uranium, sold to utilities in several countries. Production over
three years to mid 2002 averaged 3533 t/yr of uranium.
In 1980, Queensland Mines opened Nabarlek in
the same region of Northern Territory. The orebody was mined out in one
dry season and the ore stockpiled for treatment from 1980. A total of
10,858 tonnes of uranium oxide were produced and sold to Japan, Finland
and France, over 1981-88. The mine site is now rehabilitated.
At the end of 1982 Mary Kathleen in Queensland had depleted its ore
and finally closed down after 4802 tonnes of uranium oxide had been
produced in its second phase of operation. This then became the site of
Australia's first major rehabilitation project on a uranium mine site,
which was completed at the end of 1985. A Rum Jungle Rehabilitation
project also took place in the 1980s.
Australian Labor Party (ALP) policy on uranium mining has
varied over four decades. The 1971 Platform, on which the Whitlam
Government was elected in 1972, committed the party to working towards
the establishment of a domestic uranium enrichment and nuclear power
sector. But after losing government in 1975, pressure grew in the Labor
Party for a strong stance against uranium mining and export, as a
counterpoint to Liberal Coalition policies to expedite uranium mining
and export. An anti-nuclear movement gained strength and campaigned to
end Australian uranium mining.
The 1977 ALP National Conference adopted a new policy. Community
concerns with the threat of nuclear war were to be allayed by ending
uranium mining and ceasing Australia's contribution to the nuclear fuel
cycle. The change committed a future Labor government to declare a
moratorium on uranium mining and treatment and to repudiating any
commitments to mining, processing or export made by a non-Labor
government. The policy made a strong statement and was seen to provide
moral leadership.
By the time of the 1982 ALP National Conference, many in the Labor
Party were troubled about how an incoming Labor Government would
implement the party's moratorium policy. There was concern that the
repudiation of contracts would raise issues of sovereign risk and would
expose a Labor government to compensation liabilities. An amendment to
the ALP Platform in 1982 sought a compromise between the positions of
those who wanted to shut the industry down and those who felt that doing
so was neither possible nor in the national interest. It committed
Labor to a policy on uranium mining which was a classic political
compromise, the core of which endured as Labor policy for 25 years. The
policy was designed to prevent new uranium mines; limit Australia's
uranium production with a view to the eventual phasing out of mining
altogether; and provide moral leadership in ending the nuclear industry.
However, in a concession to South Australia, it also said that a
Labor government would "consider applications for the export of uranium
mined incidentally to the mining of other minerals on a case by case
basis". This was the Roxby Downs amendment, which would allow export of
uranium from Olympic Dam - a major copper and uranium deposit. So the
1982 anti-uranium policy actually authorised the development of the
world's largest uranium mine!
In the 1983 federal election the ALP won office. The 1984 ALP
National Conference then dropped the language of moratorium, repudiation
of contracts and phase-out from the Platform. For the first time the
three-mines-policy was delineated by naming Nabarlek, Ranger and Roxby
Downs (Olympic Dam) as the only projects from which exports would be
permitted. Provisional approvals for marketing from other prospective
uranium mines were cancelled.
The naming of specific mines was later deleted from the Labor
Platform in the light of the fact that Nabarlek ceased production in
1988 and under a (conservative) Coalition government Beverley started up
in 2000. The ALP policy then only allowed exports from existing mines
and prevented the establishment of new ones. This endured as a "no new
mines" policy through a change of government in 1996 until 2007, when it
was abandoned as ineffective and likely to be electorally negative due
to changed public opinion arising from global warming concerns.
Opposition to uranium mining was then left to state ALP branches and
governments. This continued in WA and Queensland until changes of
government in 2008 and 2012 respectively. (NSW and Victoria have
legislation banning uranium exploration and mining, which has not been
repealed by conservative governments.) A fourth mine, Honeymoon, started
up in South Australia in 2011.
Adapted from Senator Chris Evans speech 23/3/07 to Labor Business Roundtable, Perth.
During 1988 the Olympic Dam project
commenced operations. This is a large underground mine at Roxby Downs,
South Australia, producing copper, with uranium and gold as by-products.
Annual production of uranium started at some 1300 tonnes, with sales to
Sweden, UK, South Korea and Japan. After a A$ 1.9 billion expansion
project, production increased to over 4000 tonnes uranium per year by
mid 2001. In 2005 it was taken over by BHP Billiton.
Beverley, the first Australian in situ leach (ISL) mine started up in
2001 and closed early in 2014. Another ISL mine, Honeymoon, came on
line in 2011 and closed in 2013. Production from Four Mile started in
2014, using a satellite plant to capture the uranium from ISL and the
Beverley plant for final product recovery. Beverley and Honeymoon may
resume production with increased uranium prices.
Both Ranger and Nabarlek mines are on aboriginal land in the
Alligator Rivers region of the Northern Territory, close to the Kakadu
National Park. In fact the Ranger and two other leases are surrounded by
the National Park but were deliberately excluded from it when the park
was established. Ranger is served by the township of Jabiru, constructed
largely for that purpose. Nabarlek employees were based in Darwin and
commuted by air.

There are three operating uranium mines in Australia: Ranger in Northern Territory, Olympic Dam in South Australia, and Beverley
with Four Mile in South Australia. Four Mile has final processing
through the Beverley plant. Honeymoon was shut down in 2013 pending
improved uranium prices, and the main Beverley (and North Beverley)
wellfields were also shut down soon after that.

Ranger
The Ranger mine and associated town of Jabiru is about 230 kilometres
east of Darwin, surrounded by the Kakadu National Park, a major tourist
attraction. This is a monsoonal part of Australia, with pronounced wet
season from December to April. The first two orebodies are now mined out
and work is under way to develop an underground mine, though in the
longer term the Jabiluka orebody, 20 km away on a contiguous lease, is a
more significant prospect (see Uranium Deposits paper).
History:
In 1969 the Ranger orebody was
discovered by a Joint Venture of Peko Wallsend Operations Ltd (Peko) and
The Electrolytic Zinc Company of Australia Limited (EZ). In 1974 an
agreement set up a joint venture consisting of Peko, EZ and the
Australian Atomic Energy Commission (AAEC).
In 1978, following a wide ranging public inquiry (the Ranger Uranium
Environmental Inquiry) and publication of its two reports (the Fox
reports), agreement to mine was reached between the Commonwealth
Government and the Northern Land Council, acting on behalf of the
traditional Aboriginal land owners. The terms of the joint venture were
then finalised and Ranger Uranium Mines Pty Ltd was appointed as manager
of the project.
In August 1979 the Commonwealth Government announced its intention to
sell its interest in the Ranger project. As a result of this, Energy
Resources of Australia Ltd (ERA) was set up with 25% equity holding by
overseas customers. In establishing the company in 1980 the AAEC
interest was bought out for $125 million (plus project costs) and Peko
and EZ became the major shareholders. Several customers held 25% of the
equity in non-tradable shares. Ranger Uranium Mines Pty Ltd became a
subsidiary of ERA. During 1987-8 EZ's interest in ERA was taken over by
North Broken Hill Holdings Ltd and that company merged with Peko.
Consequently ERA became a 68% subsidiary of North Limited, and this
holding was taken over by Rio Tinto Ltd in 2000. In 1998 Cameco took
over Uranerz, eventually giving it 6.69% of ERA, and Cogema took over
other customer shares, giving it (now Areva) 7.76%.
Late in 2005 there was a rearrangement of ERA shares which meant that
Cameco, Cogema and a holding company (JAURD) representing Japanese
utilities lost their special unlisted status and their shares became
tradable. The three companies then sold their shares, raising the level
of public shareholding to 31.61%.
Production and Sales:
The mine started operating
in 1980. Full production was in October 1981 at a rate of about 3300
tonnes per year of uranium oxide concentrate. Ranger #1 open pit was
mined out over 1980-94, then pit #3 over 1997-2012. The run of mine
stockpile then comprised 1.4 Mt of ore at average 0.165% U3O8, which was treated by mid-2013. With other surface stockpiled ore averaging 0.12% U3O8
there is enough to last to 2020 if market conditions are favourable, or
at least to 2016 when underground mining is planned to commence.
However, annual production diminished from 2012 as progressively lower
grade material is processed at a constant mill rate of about 2.4 Mt/yr.
It is envisaged the lowest grade material might be blended with
high-grade ore from underground from 2016.
Uranium recovery ranges up to 93%.
Until 1990 all ERA sales of uranium concentrate were from Ranger
production. Over several years the spot price of uranium concentrates
was below the cost of production at Ranger, which made it advantageous
over 1990-97 for ERA to purchase supplies from third parties. In 1994
the level of 1510 tonnes just exceeded that year's mine production.
Further purchases were made 2001-05. The third party concentrates
concerned mostly came from Kazakhstan. In 2011 ERA purchased 2126 t U3O8 to
meet its sales commitments, including 1636 tonnes for actual 2011
sales. In 2012 about 500 t was purchased (387 t to end June). ERA sales
are mostly under contracts with customers who are prepared to pay a
price premium for long-term security of supply.
In 2013 production at Ranger was 2690 tonnes of U3O8 (2510
tU), curtailed due to closure of the treatment plant after a leach tank
failed in December. (NB ERA reports drummed production, whereas Rio
Tinto reports Ranger figures on a slightly different basis.) Operations
resumed in June 2014, but no product was drummed in that half year, and
only 1165 t U3O8 (988 tU) was produced in the full year. Mill head grade
in 2014 was 0.11% with recovery 81.5%.
All ERA uranium oxide sales are to energy utilities in Japan, South
Korea, China, UK, France, Germany, Spain, Sweden and the United States
under international and bilateral safeguards regulations. ERA supplied
about 5% of the world's uranium production in 2012. Asia is a
particularly important market, with most of the company's premium priced
contracts there supplied from Ranger.
In 2008 total energy consumption was 1457 TJ, for production of
uranium 2264 PJ (@ 500 TJ/t used in conventional reactor), ie 0.064% of
output. CO2 equivalent greenhouse gas emissions were 155,0000 t.
Ranger treatment plant, with mine pit beyond
Process:
Following crushing, the ore is ground
and processed through a sulfuric acid leach to recover the uranium. The
pregnant liquor is then separated from the barren tailings and in the
solvent extraction plant the uranium is removed using kerosene with an
amine as a solvent. The solvent is then stripped, using an ammonium
sulphate solution and injected gaseous ammonia. Yellow ammonium
diuranate is then precipitated from the loaded strip solution by raising
the pH (increasing the alkalinity), and removed by centrifuge. In a
furnace the diuranate is converted to uranium oxide product (U3O8).
Reserves & Resources:
The Ranger 1 orebody,
which was mined out in December 1995, started off with 17 million tonnes
of ore some of which is still stockpiled. The Ranger 3 nearby is
slightly larger, and open pit mining of it took place over 1997 to 2012.
In 1991 ERA bought from Pancontinental Mining Ltd the richer Jabiluka
orebody (briefly known as North Ranger), 20 km to the north of the
processing plant and with a lease adjoining the Ranger lease. ERA was
proposing initially to produce 1000 t/yr from Jabiluka concurrently with
Ranger 3. The preferred option involved trucking the Jabiluka ore to
the existing Ranger mill, rather than setting up a new plant, tailings
and waste water system to treat it on site as envisaged in an original
EIS approved in 1979. However, all these plans are now superseded – see Australia's Uranium Deposits and Prospective Mines paper.

---|---|---|
Ranger stockpile | 0.123 | 6,206 |
Total reserves | 0.123 | 6,206 |
Mineralised stockpile resources | 0.05 | 17,844 |
Measured resources in situ (Deeps) | 0.32 | 8,922 |
Indicated resources in situ (Deeps) | 0.28 | 17,366 |
Inferred resources | 0.25 | 8,579 |
Total resources | 0.10 | 52,711 |
Note: figures are based on a 0.02% cut off for open
pit resources, and 0.15% for underground resources (Ranger 3 Deeps).
Resources are additional to reserves. A large reduction in resources in
2012 was due to reclassifying in-situ low grade ores from Mineral
Resources to Mineralised Inventory as pit 3 is backfilled, sterilizing
the large pit shell resource.
In the Ranger 3 Pit and Deeps the upper mine sequence consists of
quartz-chlorite schists and the lower mine sequence is similar but with
variable carbonate (dolomite, magnesite and calcite). The primary ore
minerals have a fairly uniform uranium mineralogy with around 60%
coffinite, 35% uraninite and 5% brannerite. In weathered and lateritic
ores the dominant uranium mineralogy is the secondary mineral saleeite
with lesser sklodowskite.
In the second half of 2008 a $44 million processing plant was
commissioned to treat 1.6 million tonnes of stockpiled lateritic ore
with too high a clay content to be used without this pre-treatment.
Following initial treatment the treated ore is fed into the main plant,
contributing 400 t/yr U3O8 production for seven
years. A new $19 million radiometric ore sorter was commissioned at the
same time, to upgrade low-grade ore and bring it to sufficient head
grade to go through the mill. It will add about 1100 tonnes U3O8
to production over the life of the mine, and be essential for
beneficiating carbonate ore from the lower mines sequence of the Ranger 3
Deeps.
A feasibility study into a major heap leach operation for 10 Mt/yr of
low-grade ore showed the prospect of recovering up to 20,000 t U3O8 in
total. Column leach trials were encouraging, yielding extractions of
greater than 70% at low rates of acid consumption. The facility would
consist of fully lined heaps of material about 5m high and covering
about 60-70 ha. These will be built and removed on a regular cycle and
the residues stored appropriately after leaching is completed. The acid
leach solutions would be treated in a process similar to that used in
the existing Ranger plant and recycled after the uranium is removed from
the pregnant liquor. ERA applied for government (including
environmental) approval for the project, which was expected to begin
operation in 2014, but in August 2011 ERA announced that the plan was
shelved due to high capital costs and uncertain stakeholder support. As a
result, ore reserves of 7,100 tonnes of uranium oxide were reclassified
as resources.
In 2006 the projected operating life of the Ranger plant was extended
to 2020 due to an improvement in the market price enabling treatment of
lower grade ores, and in 2007 a decision to extend the operating Ranger
3 open pit at a cost of $57 million meant that mining there continued
to 2012. However, reassessment of the low-grade stockpile in 2011
resulted in downgrading reserves by 6100 t U3O8.
The #3 pit is now being backfilled, and to mid-2014, 31 million tonnes
of waste material had been moved there. It will then be used as a
tailings dam.
Ranger 3 Deeps
By November 2008 ERA had defined the Ranger 3 Deeps mineralisation
target in the range of 15 to 20 million tonnes, and this has been
confirmed as containing 34,000 tonnes of uranium oxide reported in the
figures above. The mineralised zone has a strike length so far
identified of about 1.2 kilometres between 250 and 550 metres from the
surface, immediately east of the pit, and remains open to the north.
Following regulatory approval in 2011, ERA awarded a A$50 million
contract to McMahon Holdings for establishing a boxcut near pit 3 and
2.2 km decline in preparation for its own further drilling program. The
decline reached a depth of 500 metres, and was built to handle eventual
production. Work began in May 2012 and it was completed at the end of
2014, on schedule and on budget.
In June 2012 ERA approved spending A$57 million on a pre-feasibility
study of the project to 2014, including 16,000 m of drilling. In January
2013 ERA applied for environmental approval of the Ranger 3 Deeps
exploration decline project. In total the company planned to spend A$120
million on the project, plus a $57 million prefeasibilty study, leading
towards a decision to mine early in 2015. About half the tailings from
the underground ore will be returned there, and the mine footprint will
shrink from 68 ha for pit 3 to 2 ha for the decline. In October 2014 the
company lodged a draft EIS for the mine project, targeting first
production at the end of 2015.
In June 2014 the company announced an update of resources in Ranger 3
Deeps after two-thirds of the drilling program was completed. A total
of 32 km of drilling had been undertaken, and the decline reached 2221
metres from the surface. Total resources were 32,620 tonnes U3O8
averaging 0.274% grade at 0.15% cut-off, two-thirds in the upper mine
sequence and one-third in the lower, which has higher carbonate levels.
The pre-feasibility study (PFS) will be considered by the Board early in
2015.
ERA plans to complete processing by Jan 2021 and complete $640
million site rehabilitation by 2026; these dates are not flexible, so
prima facie will need to include all underground mining and treatment of
any other ore (e.g. northern deposits on the Ranger lease).
Occupational Health & Safety:
Radiation
doses received by employees are all well below recommended limits. The
designated employees (most exposed to radiation) received an average
dose of 1.3 millisieverts per year above natural background in 2008
compared with the recommended annual limit of 20 mSv averaged over 5
years. In first half of 2007 the maximum dose to any person was 3.9 mSv,
hence less than 8 mSv/yr.
ERA’s occupational safety and health management systems are certified
to AS4801. In 1994 ERA was the first Australian mine to be awarded a
5-star rating by the National Safety Council, putting it in the top 5%
of all industry occupational health and safety performance.
Infrastructure:
Along with building other infrastructure used by the public, the Company set up the town of Jabiru nearby. While it was initially envisaged that this would be solely a mining town, it has become an important regional centre for tourism and government services, including management of the National Park. Some 200 000 tourists visit the area each year.
Environmental Management
ERA has been recognised for its world-class environmental management, achieving ISO 14001 certification in 2003.
Until 1996 tailings from the treatment plant were emplaced in an
engineered dam on the lease. They were then deposited into the worked
out #1 pit, and later to the tailings dam which was raised from RL 36 m
to RL 60.5 m. No process or other contaminated water is released from
the site, but concerns were raised about seepage from the tailings dam,
and in 2009 the Supervising Scientist estimated this at 100 m3/day.
Consequently the Gundjeihmi Aboriginal Corporation negotiated an
independent hydrological review of the situation which resulted in many
(79) more monitoring bores being established and a greatly improved
seepage model. This will provide helpful data for the rehabilitation of
the tailings area by 2026.
The Ranger mine is on a 7860 hectare lease which is surrounded by the
World Heritage listed Kakadu National Park of 1.98 million hectares.
About 500 hectares is actually disturbed by the mining and milling
activities (0.025% of the total area).
Rainfall is monsoonal, with 700-2200 mm (average 1540 mm) falling in
the wet season. The vegetation at Ranger is tropical open eucalypt
forest, similar to much of the National Park.
The project area is leased from the Aboriginal traditional owners,
title to the land being held by the Kakadu Land Trust. The Company
contributes 4.25% of its gross sales revenue (the major part of its
royalties of 5.5%) to NT aboriginal groups plus an annual rental of $200
000 for the use of the land. Ranger has paid a total of $345 million to
aboriginal interests, including royalties, since the project began in
1980, in addition to jobs and community and social contributions. The
royalty money is paid to the Commonwealth Government and then
distributed to Northern Territory-based Aboriginal groups, including 30%
to the Gundjeihmi Aboriginal Corporation (representing Traditional
Owners), under the 1979 terms of the Commonwealth's Aboriginal Land
Rights (NT) Act of 1976. Additional payments of over $7 million are on
account of Jabiluka. The balance of royalty (1.25% of revenue) is paid
to the NT government by the Commonwealth Government.
The Company has a substantial environmental division, employing about
30 people and with an annual budget of nearly A $3 million. Part of
this environmental effort is directed to land management issues of
relevance not simply to Ranger, but to the surrounding National Park and
World Heritage area. These include maintenance of biodiversity, fire
management including control burning (which is very important and
contentious in the region), terrestrial and aquatic weed control, feral
animal control, mycorrhizal establishment, and rehabilitation of
disturbed areas (including rock waste dumps, etc). Ranger is possibly
the first mining operation deliberately to burn its own revegetated
areas to assist the development of an appropriate vegetation community
(Eucalypts and Grevilleas instead of Acacia dominance). Related issues
being studied include artificial wetland filters, soil formation from
waste rock, and hydrology.
Among Ranger's long term research priorities are projects which are
relevant to eventual use of the land by its aboriginal owners.
ERA's success in environmental management has given rise to a
consultancy, Earth Water Life Sciences, which gained significant
business based on Ranger's environmental reputation.
Notwithstanding any results that may come from the ongoing
exploration program, the company developed its plans for mine closure
early in its history. A mine closure model has been prepared, and
circulated to stakeholders, resulting in an estimate of the technical,
environmental, social and other costs, through to final closure on both
the Ranger project area and surrounds. This closure model is now the
subject of review and refinement internally and with stakeholders. This
model, which is progressively refined, has been used as the basis for
calculating the financial provision required for eventual closure at the
end of mine life. At the end of 2005 the net present value of the
closure model for the Ranger project area and surrounds was estimated at
A$186 million, fully provided for in the balance sheet. In mid 2011
the provision for rehabilitation and closure had grown to $550 million,
with detailed studies continuing into 2012. In 2013 the estimate was
$640 million.
In 2013 ERA was carrying out a $23 million prefeasibility study on an integrated tailings, water and closure strategy, work on which was ready to commence. Some 10 Mt backfill had been placed into pit 3 by mid 2013, and the company will dredge the tailings dam and send 4.4 Mt /yr to pit 3 from 2015, with the remainder of low-grade ore after 2020. Waste rock will be used as capping. Much of the cost of rehabilitation is a $220 million brine concentrator to clean up tailings water for discharge, using heat. It produces a brine (at pH 1.8 and TDS 400,000 ppm) retained in pit 3 which is retained in pit 3, and 1.83 GL/yr of clean water, and was commissioned in September 2013.

ERA, separately, is obliged to secure funds for certain costs of
rehabilitation in case of any need for premature closure. An annually
amended plan is submitted to government outlining this provision, which
is reviewed by an independent auditor. Money for this purpose is partly
in a trust fund administered by the Commonwealth government and partly
covered by bank guarantee. At the end of 2008, security of $149 million
was held by the Commonwealth Government in respect to Ranger, and a
further $1 million for Jabiluka.

Olympic Dam
The Olympic Dam
copper and uranium mine, with the town of Roxby Downs, is located 560
km north of Adelaide, near the opal mining centre of Andamooka. This is
an arid part of Australia, receiving only an average of only 160 mm of
rain per year, and that rather unreliably. The massive deposit is
underground, some 350 metres below the surface, and besides its primary
significance as a copper orebody, it is the largest known uranium
orebody in the world.
History:
The deposit was discovered in 1975 by
Western Mining Corporation Ltd which was looking for copper in buried
sedimentary rocks. After considering geophysical data a drill hole was
sunk near a small stock water dam known as Olympic Dam. It struck
copper, and later drilling confirmed a resource of more than 2000
million tonnes of ore containing both copper and uranium. From 1979 the
deposit was evaluated as a Joint Venture with British Petroleum Ltd. In
1985 it was decided to proceed with the project, and production
commenced in 1988.
WMC (Olympic Dam Corporation) Pty Ltd is the management company, a
wholly-owned subsidiary of BHP Billiton Limited, which took over WMC
Resources in mid-2005. Initially BP Minerals Ltd was a 49% partner in
the enterprise, but WMC took over BP Minerals' share in 1993 for $315
million.
Over 1996-99 WMC undertook a A$ 1.25 billion program to more than
double annual production to 200,000 tonnes copper and 3700 tonnes
uranium concentrate (from 1500 tonnes). This expansion program was then
accelerated, with the cost eventually rising to A$ 1.94 billion and the
uranium capacity to 4600 tonnes U3O8 per year (which later declined to 4100 t/yr with decreasing grades).
OD Expansion: WMC plans
Before the mid-2005 takeover by BHP Billiton, WMC Resources committed
A$ 50 million over two years to assess the potential for doubling the
size of Olympic Dam and in particular to take the resource
categorisation of the southern orebody through to proven reserves and
thus demonstrate the viability of a much expanded operation – up to
15,000 t/yr U3O8 (with 500,000 t/yr copper). The
capital cost involved was estimated as at least A$5 billion. Some $4
billion had already been invested in the mine by WMC, including $680
million over 2001-04, and in 2004 the mine generated A$ 1100 million in
export income. The WMC study included drilling on the southern deposit
and assessing mining options including possibly a massive open pit (3 km
wide, 1 km deep) to access the orebody. Up to June 2007 over 2000 km of
drilling has been involved in defining the orebody.
OD Expansion: BHP open pit plans
BHP Billiton then made a fresh appraisal of the possibilities on the
basis that the previous assessment of market potential was too
conservative. A pre-feasibility study to decide among the development
options, and a 4600-page draft environmental impact study, were
completed in 2009. The EIS (summary p20) states: "Drilling of the ore
body undertaken by BHP Billiton since 2005 has more than doubled the
resource estimate from 3.98 billion tonnes of total mineral resource to
8.34 billion tonnes. At the same time, the expected demand and prices
for the minerals means underground mining is no longer the preferred
option for such a large ore body. Consequently, open pit mining has
become the most feasible option for mining more of the resource.
Underground mining can extract only about 25% of the ore containing
recoverable quantities of copper, uranium, gold and silver, while an
open pit would extract up to 98% as large zones of lower-grade
mineralisation that were uneconomical for underground mining can be
profitably bulk mined."
OD Expansion: BHP reduced smelting plans
In mid 2007 BHP Billiton proposed an alternative treatment strategy,
which became part of the base case. This would involve exporting some
product as copper concentrate rather than only refined copper, and hence
exporting some uranium still contained in the copper concentrate.
Because the Olympic Dam ore contains copper, uranium, silver and gold in
close association, the common procedure of simply selling a copper
concentrate with precious metals has not been viable, since some of the
uranium would be in it, creating both processing and safeguards
complications for the smelter operator. Most of the uranium is removed
at the flotation stage when the copper sulfide is separated from the
remainder of the ore, which is then tailings, and the main uranium
recovery is from acid leaching of these tailings. Secondary uranium
recovery is from acid leaching the copper concentrate, which then goes
on to be smelted, containing about 45% copper and up to 0.15% uranium.
At present smelting is done at Olympic Dam, followed by electro
refining, and the further traces of uranium are recovered at these
stages.
The proposal then became to export much of the copper concentrate
with enough uranium still present to require the application of
safeguards, so that it was all accounted for. Hence smelting could only
be undertaken in one of 36 countries with which Australia has a
bilateral safeguards agreement, plus the heavy industry infrastructure
required. China is the prime destination and could build dedicated
facilities, as could Japan.
With eventually two thirds of the copper concentrate from the
expanded Olympic Dam operation being exported as concentrate, up to 2000
tonnes of uranium would be involved annually. The major part of the
uranium - about 14,400 t/yr, would be recovered and processed as at
present (see below). This copper concentrate export strategy for the
expanded production from Olympic Dam would diminish the investment cost
of the expansion, since smelting and refining for most of the copper
increment will not be required. The infrastructure needed at Olympic Dam
to operate it - notably electricity - would also be less. A new smelter
in China or Japan would be lower cost. However, unless it was owned and
operated by BHP Billiton itself, there would be no flexibility in
concentrate sales.
Plans for expansion of the mine would mean that 800,000 t/yr of
copper concentrate derived from the higher-grade ore was smelted at site
to produce 350,000 t/yr of refined copper product, and 1.6 million
tonnes would be exported to be smelted in China or Japan to yield about
400,000 tonnes of refined copper. This lower-grade portion (mostly
chalcopyrite – CuFeS2) would have up to 2000 t of uranium in
it (not more than 15% of total U) to be recovered there. Total uranium
production would then be 14,400 tU from the hydrometallurgical plant on
site and 1700 tU from the exported concentrates, total 16,100 tU (19,000
t U3O8) per year. Gold production would be 25 tonnes per year.
OD Expansion: BHP staged development plans
In October 2008, five stages of this expansion were defined, without
specific timeline, and in May 2009 the time span of progressive
development was estimated as about 11 years from 2010. The open pit
would be developed over five years, removing overburden to expose the
first part of the main orebody. Mining from it would then commence mid
2016, and the pit would continue to be developed.
The main metallurgical plant (concentrator) would be developed in
three successive 20 Mt/yr stages from 2012. A new hydrometallurgical
plant to treat the tailings from this would be developed in conjunction.
The existing electro-refinery and smelter would be upgraded to continue
processing ore from either the existing (and continuing) underground
operation or the open pit.
The pit will eventually be 4.1 x 3.5 km, and 1000 m deep, and the
waste rock storage about 67 square km to a height of 150 m. Tailings
storage would extend the existing facility to about 40 sq km and 65 m
high to take 58 Mt/yr.
Required infrastructure would include a 280 ML/day desalination plant
(reverse osmosis) on Spencer Gulf, supplying 200 ML/day to the
operation; much increased power provision by 650 MWe; a 105 km rail
spur; a new airport; accommodation expansion at and near Roxby Downs.
Some of the power increment – about 250 MWe – could eventually be met by
a cogeneration plant harnessing waste heat from burning sulfur at the
acid plant. Most of it would need to come either from the grid or a 600
MWe combined cycle gas turbine plant at Olympic Dam.
A draft Environmental Impact Study was released on 1 May 2009.
Following feedback, a Supplementary EIS was submitted to government in
December 2010 and government approval of the proposal was announced in
October 2011. BHP Billiton moved the project to feasibility study stage
in March 2011, but in August 2012 put the $28 billion project on hold
while it investigated less-costly alternatives.
OD Expansion: BHP underground expansion and heap leach plans
In July 2014 BHP Billiton applied for government approval to build
and operate a demonstration-scale heap leaching plant at Olympic Dam.
Heap leaching has not previously been used for uranium ore in Australia
(that at Rum Jungle over 1965-71 was for copper), though it is
increasingly favoured for low-grade hard-rock uranium ores overseas.
BHP-B uses it on a large scale at its Spence copper mine in Chile.
Laboratory and pilot scale trials of the technique using run of mill ore
from the existing operations have shown promising results to date. The
company expects to start construction of the demonstration plant in the
second half of 2015, with a three-year trial period starting in late
2016.
Some 36,000 tonnes of ore – about one day's current mine production – will be used in the trial. The ore will be crushed, placed on an impermeable leach pad and treated with sulphuric acid for 300 days. This is expected to recover most of the uranium, and with the help of bacteria, something like half of the copper. The uranium would then be removed from the pregnant liquor by solvent extraction, after which the copper would be removed electrolytically. This essentially reverses the present sequence where most of the uranium is recovered by acid leaching the mill tailings after copper sulphide flotation. Following the heap leaching, the depleted ore remaining will be further crushed, ground and put through a dedicated flotation plant on site to recover the rest of the copper as sulphide, which would then be smelted as at present for all production.

In a general announcement about productivity in November 2014, BHP
Billiton flagged a 27% increase in copper production at Olympic Dam from
2018 by streamlining haulage and treatment, and a doubling from that
level subsequently by “a low-risk underground expansion with
significantly lower capital intensity than the previous open cut design.
This has the potential to deliver over 450,000 tonnes of copper
production a year at first quartile C1 costs by the middle of next
decade.” The uranium implications are not mentioned, but assuming the
same head grades, it would mean 5000 t U3O8 from 2018 and some 10,000 t/yr in mid-2020s.
Production and Sales:
Olympic Dam is an underground mine. Some 12 million tonnes of ore is mined each year by open stoping.
In 2001 the plant suffered a fire in the solvent extraction plant and
production remained low for two years. In October 2009, the haulage
system in the mine's Clark Shaft was damaged. While hoisting continued
at the secondary Whenan Shaft, capacity was reduced to about 25% until
full production resumed in June 2010.
In 2013 production was 4008.7 tonnes U3O8
(3399 t UOC, 3386 tU) – about 6% of world mine total. Uranium recovery
has been 65-70%, due to about half of the uranium being in the form of
refractory brannerite, and this is a focus for improvement, with 72.8%
recovery being achieved in 2008.
Sulfur dioxide from the copper minerals is made into acid and used in uranium processing.
Sales figures are understood to be close to the production figures.
About 20% of the revenue is from uranium, 75% from copper and 5% gold and silver.
Sales of uranium concentrate are made under long-term contracts to
electric utilities in Canada, USA, Japan, South Korea, China, Finland,
Sweden, Belgium, France and the United Kingdom.
Process:
Following primary crushing underground,
the ore is ground and treated in a copper sulphide flotation plant.
About 80% of the uranium minerals remain in the tailings from the
flotation cells, from which they are recovered by acid leaching. The
copper concentrate is also processed through an acid leach to recover
much of the other 20% of the uranium. The pregnant liquor is then
separated from the barren tailings and in the solvent extraction plant
the uranium is removed using kerosene with an amine as a solvent. The
solvent is then stripped, using an ammonium sulphate solution and
injected gaseous ammonia. Yellow ammonium diuranate is then precipitated
from the loaded strip solution by raising the pH, and removed by
centrifuge. In a furnace the diuranate is converted to uranium oxide
product, U3O8.
Some uranium remains in the leached copper concentrate which goes to
be smelted, and it is recovered in the smelting or electro refining
stages.
Ore:
The deposit occurs in the basement rocks of
the Stuart Shelf geological province in the north of South Australia.
Mineralisation consists of medium-grained chalcopyrite (CuFeS2), bornite (Cu5FeS4) and chalcocite (Cu2S),
fine-grained disseminated pitchblende and brannerite (U minerals),
gold, silver and rare earth minerals that occur in a magnetic
hydrothermal breccia complex beneath 350m of overburden. The ore occurs
in distinct zones that determine the mine access and layout.
(mining-technology.com & infomine)
Reserves & Resources:
Olympic Dam has
enormous reserves of ore, with 347,000 tonnes of contained uranium
oxide. The overall resource contains some 2.45 million tonnes of uranium
oxide in a hematite breccia complex. While the grade of the uranium ore
is lower than many mines or potential mines which have the benefit of
open cut operation, the fact that copper is a co-product with uranium
from that same ore (at 1.8% Cu in the reserves) means that such grades
are viable.

The
figures announcing a 27% increase in uranium resources, to 2.24 million
tonnes of uranium oxide (1.9 MtU) in September 2007 were based on 2095
km of drilling over the previous two years and confirmed the deposit as
the world's largest for uranium. It covers an area of over 6 km by 3.5
km, is up to 2 km deep and remains open laterally and at depth as the
drilling program continues, further results being reflected in the above
Table.
Occupational Health & Safety:
The mine is
well ventilated with powerful fans so that radiation exposure from radon
daughters is very low. Exposure from gamma radiation is also minimal,
due to the low grade of uranium mineralisation. The average annual
radiation exposure level (over the 1.5 mSv/yr background) for all
designated underground workers in 1999-2000 was 1.7 millisieverts
(ranging up to 9.9 mSv). These levels compare very favourably with the
annual limit of 20 mSv/yr averaged over five years.
The site has implemented a Safety Management System which is
compliant to Level 3 Exempt Status under the state occupational safety
organisation, and this has been officially recognised.
Infrastructure:
Expansion of the mine will bring
major infrastructure challenges. The present 12 GL/yr water consumption
(met from the Great Artesian Basin) will grow, possibly to 70 GL/yr,
requiring a coastal desalination plant with pipeline to Olympic Dam.
The operation now uses 10% of the state's base-load power (870 GWh/yr)
and the expansion will add demand for another 650 MWe and 4400 GWh/yr,
the source of which remains to be determined. The CO2 output from power generation attributable to the operation is likely to grow from 0.9 to some 4.7 Mt/yr.
Environmental Management
The mine lease of 18,000 hectares is managed by BHP Billiton Olympic
Dam. The mine, smelter and infrastructure occupy about 7.5% of the lease
area. Environmental management activities account for approximately one
third of expenditure from the overall environmental budget, which is in
excess of A$ 2 million. In February 2005, Olympic Dam was successful in
obtaining ISO14001 certification for the site Environmental Management
System.
The mine lease and the adjacent 11,000 hectare municipal lease have
been destocked (of sheep and cattle) since 1986. Following the release
of rabbit haemorrhagic disease (RHD), rabbit numbers in the region
dropped significantly, and are currently at approximately 40 per square
kilometre, compared with plague numbers of up to 600 /km2 in
the late 1980s. Red Kangaroo numbers on the mine lease are about 20 per
square kilometre, which is slightly higher than surrounding areas
because of the access to water. In order to discourage wildlife from
entering the tailings storage facility, alternative waterholes have been
provided and deterrents installed on the dams and ponds. The
evaporation ponds have been fenced with fine mesh to exclude small
mammals and reptiles. Foxes and cats are controlled on the lease by
shooting and trapping.
BHP Billiton Olympic Dam manages four pastoral stations in the area
surrounding the mine and municipal leases with a total area of 1,136,000
hectares. These properties are conservatively stocked to maximise
protection of sites of environmental or cultural significance.
The Arid Recovery project, which covers an area of 8,600 hectares, is
situated largely on the mine lease and BHP Billiton-operated pastoral
stations, with the remaining area (6 hectares) donated by local
pastoralists. Arid Recovery is an ecosystem restoration initiative
working to restore Australia's arid lands. The program is a partnership
between BHP Billiton, the South Australian Department for Environment
and Heritage, the University of Adelaide and the community group Friends
of Arid Recovery. The reserve is surrounded by a unique cat, rabbit and
fox-proof fence. Five locally extinct species have been reintroduced
into the reserve.
Before clearing is undertaken for any development work or exploration
on the mine and municipal leases, an Environmental/Indigenous Heritage
Clearance Permit is required. During this process, all significant
slow-growing trees and shrubs and areas of cultural significance are
identified. Efforts are made to minimise disturbance caused by
operational activity on the leases, and rehabilitation is undertaken
afterwards where practical. Considerable attention has been given to
rehabilitation of the hundreds of drill pads, some dating from initial
exploration, so that many are now scarcely visible even on aerial
photos.
Rock waste and the coarse fraction of tailings are used as mine
backfill. Fine tailings material, still containing potentially valuable
minerals (rare earths etc.) is emplaced in tailings dams on the lease
covering about 400 hectares.
During 1994 seepage of contaminated water from the tailings dams was
identified. This was of concern to the company, the regulators and the
public because of the perceived threat to the quality of groundwater
immediately below the tailings dams. Studies undertaken demonstrated
that the pollutants in the seepage were quickly adsorbed on to clays and
limestone in the soil and rock under the tailings dams, and, due to the
low permeability and transmissivity of the rock, that there was no
potential harm to the groundwater resource. The level of the groundwater
under the tailings dams is monitored and modelled on a quarterly basis.
BHP Billiton Olympic Dam submits an Environmental Management and
Monitoring report annually to the Department of Primary Industries and
Resources South Australia (PIRSA) and the Environment Protection
Authority (EPA). This comprehensive report covers all areas of potential
environmental impact, including air emissions, site groundwater
management, water supply and management of the Great Artesian Basin,
flora and fauna monitoring and annual radiation dose to members of the
public. Reporting on progress with action items identified in the
Environmental Management Program is provided, as well as involvement
with community activities.
The annual Sustainability Report is on the web
http://bhpbilliton.com/bb/sustainableDevelopment/reports.jsp
http://bhpbilliton.com/bb/sustainableDevelopment/reports.jsp
Olympic Dam has a Rehabilitation and Closure Plan covering cost
estimate basis, summary of closure requirements (for the metallurgical
facilities, pilot plant, mine, tailings dams, wellfields, exploration
areas, town facilities, power line corridor and miscellaneous
facilities), community consultation requirements, closure strategy
(including post operational land use objective and completion criteria)
and closure plan review requirements. The plan provides a breakdown for
each area to be decommissioned, including engineering works required (ie
demolition and cleaning), environmental works (removal of contaminated
material and rehabilitation), specific closure obligations for each area
of plant, final land use objectives, closure assumptions, closure
material sources, waste disposal sites, cost saving opportunities and
liabilities/risks/hazards.
Demolition costs are budgeted based on quotations from a specialist
demolition contractor and rehabilitation costs are estimated based on a
quotation from a mining contractor with extensive rehabilitation
experience. Progressive closure costs have been estimated for each year
until actual closure of the site. The financial provision – A$ 244
million at mid-2006 – is calculated in line with BHP Billiton Accounting
Standards.
Beverley and Four Mile
Over 2013-14 the scene has changed here, with Beverley and then
Beverley North suspending production, and after January 2014 all
production coming from Four Mile.
The Beverley uranium deposit is 520 kilometres north
of Adelaide, on the plains north-west of Lake Frome and 25 kilometres
north east of the Arkaroola Resort in the northern Flinders Ranges.
Beverley North is contiguous. Beverley itself is a relatively young
sandstone deposit with uranium mineralisation leached from the Mount
Painter region, and was the basis of Australia's first commercial in
situ leach (ISL) operation. In 2008 a major mine lease extension was
obtained to the north so that the lease is now contiguous with the Four
Mile lease to the north and west of it.
History and Background:
Beverley was discovered in 1969 by the OTP Group (Oilmin NL, Transoil
NL, & Petromin NL). A draft EIS was produced in 1982 but plans to
mine it by in situ leaching (ISL) were abandoned in 1983 when a
newly-elected South Australian Government made it clear that mining
leases would not be approved. The deposit was sold to Heathgate Resources Pty Ltd, an affiliate of General Atomics of USA, in 1990.
The main Beverley deposit consists of three mineralised zones (north,
central and south) in a buried palaeochannel (the Beverley aquifer) in
tertiary sediments of the Frome basin. Groundwater salinity ranges from
3000 mg/L total dissolved solids in the north to 12,000 mg/L TDS in the
south. The aquifer is isolated from other groundwater, notably the Great
Artesian Basin about 150 metres below it and small aquifers in the
Willawortina Formation above, which are used for stock watering.
A field leach trial in 1998 was successful, with performance three
times better than similar deposits in USA, and it established the
commercial viability of the project. A new draft EIS was released for
public comment in July 1998 and the Supplement in October, with
environmental approval being given in March 1999. Other approvals were
in April 1999. Mine construction started in 1999, including processing
plant, camp, airstrip, 4.0 MWe gas-fired power station and two
wellfields.
As the main orebodies became depleted, in 2009 the Beverley North
project was initiated and in 2010 a field leach trial at Pepegoona was
successful. This became a satellite operation, with loaded resin being
trucked to the treatment plant. In 2011 mining commenced at Pannikin,
with a second satellite plant. These northern orebodies are closer to
the Flinders Ranges and more complex geologically than the main
palaeochannel deposits. The satellite plants are on the lease boundary
with the Four Mile JV with Alliance Resources. In December 2013
production from the Beverley wellfields was suspended, leaving only
Beverley North operational for Heathgate, but this too was suspended in
January 2014.
Four Mile comprises two deposits 5-10 km NW of the
Beverley mine and was explored by Quasar Resources Pty Ltd (a subsidiary
of Heathgate Resources). The extended Beverley mine lease is
contiguous. Alliance Resources Ltd through subsidiary Alliance Craton
Exploration (ACE) is a 25% free carried joint venture partner. The West
deposit has 14,000 t indicated resources and 4700 t inferred resources,
at 0.34%, and the East deposit has 13,000 tonnes at 0.31% inferred
resources, making a total of 32,000 t U3O8 at
0.33% (27,100 tU at 0.28%U). Both deposits remain open, with potential
for further resource upgrade. They are about 3 km apart.
Quasar applied for a mining lease in May 2008. An environmental
assessment was published in January 2009. The mining lease was subject
to registration of a Native Title Mining Agreement (NTMA), which was
delayed, but a 10-year mining lease was granted to the partners in April
2012, and environmental approval in August 2013. Quasar commenced
mining the East orebody in April 2014, using its nearby Pannikin
satellite plant 2.5 km away, and then trucking the loaded resin to
Heathgate’s main plant 10 km away for product recovery.
Quasar has been drilling a further area on Alliance's lease, at Four
Mile Northeast, centred some 1200 metres northeast of the East orebody
and close to Heathgate’s Pannikin satellite plant. This is highly
prospective, but no JORC-compliant figures are yet available.
Quasar has used its 75% interest to dictate development policy and
timing for Four Mile. Alliance has dissented and taken legal action, but
in June 2014 Alliance settled with Quasar, paying out $4.557 million
for costs. Alliance contends that a separate treatment plant for Four
Mile would be better economically than paying Heathgate to process the
loaded resin. In May 2012 Alliance had entered an agreement with Itochu
Corporation to take a 14.9% share in the company and then possibly 25.1%
more. If both options were exercised the company would have been able
to fund a stand-alone ISL operation at Four Mile, independently of
Heathgate and the toll treatment at Beverley. Itochu taking up the
equity was contingent upon restoration of Alliance’s full ownership of
the deposit, which did not happen. In July 2014 Alliance solicited bids
to buy its share of Four Mile.
For Beverley, Heathgate negotiated a royalty equivalent to 2% of
gross sales with four Aboriginal Native Title Claimant groups, and the
first payments totalling more than $100,000 were made to trust accounts
in mid-2000. The agreements also provide for training, employment,
community payments and administration payments.
Production and Sales:
Production from Beverley, licensed to reach 1180 t/yr U3O8
equivalent, commenced from the north mineralised zone in November 2000
though no product was drummed until 2001. Exports commenced in 2001.
Production for 2004 reached 1084 tonnes U3O8 but
then steadily dropped to around 400 tonnes from 2010 and in 2013, the
last full year of operation involving the main orebodies, 98% of
production was from Pepegoona and Pannikin on the Beverley North lease
until production ceased there in January 2014. These Beverley North
orebodies are adjacent to Four Mile. Sales contracts are with power
utilities in USA.
From Four Mile, Quasar expected to spend A$ 77 million, excluding any
development of the West orebody. Cash operating costs (A$28) plus
development costs to end of 2014 work out to about A$ 40/lb U3O8, with sale price expected to be A$ 49/lb. The production rate in mid-2014 was 1200 t/yr U3O8, which is about the capacity of the Beverley mill. In 2014, 755 t U3O8 was produced. The first two shipments of product (total 213 t U3O8) were in September and October 2014, to Cameco Blind River, and the balance was stockpiled.
For the 13 months from December 2014 through 2015 Quasar anticipates production of 1200 t U3O8
from Four Mile, which will all be stockpiled. Expenditure of $108
million is planned, including capital. Cash operating costs are budgeted
at $32/lb plus development costs of $9, total $41/lb U3O8.
Due to Quasar’s refusal to sell product, thereby depriving Alliance
of funds, ACE has refused to contribute to the 2015 program and budget.
This means that ACE’s share of the project will reduce from 25% to about
15% by the end of 2015. In November 2014 ACE terminated Quasar's
appointment as sales and marketing agent of ACE's share of Four Mile
product and instituted proceedings in the Supreme Court of South
Australia seeking a declaration that the termination is valid and to
order that ACE's share of product be delivered up to ACE. In February
2015 Alliance received an offer from Quasar to purchase all of ACE’s
interest in the Four Mile Project, including ACE’s share of uranium
oxide concentrates already mined (worth over $20 million), for AUD $57.6
million. Alliance rejected the offer but remains open to selling ACE's
interest in the project.
Resources:
At Beverley, several ore lenses in unconsolidated sands lie at a
depth of 100-130 metres, over some 4 km of palaeochannel. The three
initially mined contained at least 21,000 tonnes of uranium oxide at
0.18% grade, mostly recoverable by in situ leaching. In November 2006
the company applied to extend the mine lease to take in contiguous
ground at Beverley North including Pepegoona (with 4000 t U3O8) and Pannikin. The cumulative total recovered from Beverley and Beverley North to shut-down in January 2014 was 8614 tonnes U3O8.
At Four Mile, the West deposit has 14,000 t indicated resources and
4700 t inferred resources, at 0.34%. Alliance in June 2009 confirmed
13,000 tonnes U3O8 at 0.31% inferred resources for the East deposit, making a total of 32,000 t U3O8 at
0.33% (27,100 tU at 0.28%U). A cut-off of 0.5 metres at 0.10 m% grade
thickness (GT) was used for both resource estimates, assuming ISL
mining.* Both deposits remain open, with potential for further resource
upgrade. They are about 3 km apart. There are three mineralised layers
between 190 and 210 metres deep, ranging from 1.1 to 7.3 metres thick
and with grades up to 1.74% U3O8.
* ISL resources are reported in terms of grade thickness (GT) – average grade U3O8 multiplied by thickness of leachable sand holding the uranium.
Some additional mineralization has been identified in the western
area of Four Mile West, which has the potential to add up to 30% to that
resource if this mineralization is proved recoverable by ISL, or
mineable by other means.
For Four Mile Northeast, some 1200 metres northeast of the East
orebody and close to Heathgate’s Pannikin satellite plant, Alliance has
an exploration target of 32,000 to 36,500 t U3O8 grading 0.27-0.30% U3O8
over 2.2 km strike length, with a JORC-compliant inferred resource
figure pending (24 Feb & 20 March 2015). The exploration target
figure is for an area stretching from Four Mile East past Pannikin
almost to Pepegoona, though the mineralisation is interpreted to lie
within an apparent regional roll-front type redox interface that
embraces the Four Mile West, Four Mile East, Pannikan and Pepegoona
deposits over a total strike length of 7.5 km.
Process:
The mines consist of wellfields which are progressively established
over the orebody as uranium is depleted from sections of the orebody
immediately underneath. Wellfield design is on a grid with alternating
extraction and injection wells, each of identical design and typical of
normal water bores. The spacing between injection wells is about 30
metres with each pattern of four having a central extraction well. A
series of monitor wells are situated around each mineralised zone to
detect any movement of mining fluids outside the mining area.
Beverley wellfield
Submersible electric pumps initially extract native groundwater from
the host aquifer prior to the addition of uranium complexing reagents
(acid) and an oxidant (hydrogen peroxide or oxygen) before injection
into the wellfield. The wells are cased to ensure that liquors only flow
to and from the ore zone and do not affect any overlying aquifers. They
are pressure tested before use. The leach liquors pass through the ore
to oxidise and dissolve the uranium minerals in situ. The pregnant
solution from the production wells is pumped to the treatment plant or
satellite plant where the uranium is recovered in a resin ion exchange
(IX) system. If at a satellite plant, the loaded resin is trucked to the
central treatment plant.
The uranium is then stripped from the ion exchange resin, and
precipitated with hydrogen peroxide. The uranium slurry is dewatered and
dried to give hydrated uranium peroxide (UO4.2H2O)
product. From 2010 it was expected that the plant would also treat
loaded resin trucked in from the Four Mile project adjacent to the
Beverley North satellite operations. In fact, from 2011 it treated resin
trucked from Pepegoona and Pannikin, further north than this, and 70m
from the Four Mile lease boundary. In April 2014 it commenced recovery
of uranium from the Four Mile JV, with the resin loaded at the Pannikin
satellite plant.
Before the remaining process solution is reinjected, it is oxygenated
and if necessary recharged with sulfuric acid to maintain a pH of about
2.0 to 3.0. Most of the solution is returned to the injection wells,
but a very small flow (about 0.5%) is bled off to maintain a pressure
gradient in the wellfield and this, with some solutions from surface
processing, is treated as waste. It contains various dissolved minerals
such as radium, arsenic and iron from the orebody and is reinjected into
approved disposal wells in a depleted portion of the orebody. This
bleed of process solution ensures that there is a steady flow into the
wellfield from the surrounding aquifer, and serves to restrict the flow
of mining solutions away from the mining area.
Occupational Health and Safety:
The usual radiation protection measures are applied, despite the fact
that most of the orebody¹s radioactivity remains well underground and
there is hence minimal increase in radon release and no ore dust.
Designated employees wear personal dosimeters to measure exposure to
gamma radiation and radon daughter concentration is measured regularly
in the plant area. Routine monitoring of air, dust and surface
contamination is also undertaken.
Environmental Management:
An Environmental Management and Monitoring Plan (EMMP) has been
developed with the regulating authorities, who determined the
requirements of it, including those for radiation protection. The Plan
provides for ongoing management of every aspect of the operation.
Monitoring to detect possible horizontal excursions from the mining zone
or any vertical leakage into other aquifers is a fundamental facet of
mine operations.
In contrast to the main ISL operations in USA extracting uranium from
aquifers with potable water, the groundwater quality at Beverley is
very low, being fairly saline and orders of magnitude too high in
radionuclides for any permitted use to start with. Fluids from mined
areas are progressively moved to new mining areas, thus reducing the
overall effect on the aquifer. After completion of mining, when oxygen
input and leaching are discontinued, the groundwater reverts to about pH
4.5, and then over time to its original condition at about pH 7.
Heathgate bought the 2350 sq km Wooltana pastoral lease, from which
the 13.5 sq km project area is fenced off and destocked. This area,
mainly Mitchell grass plain, will be allowed to rehabilitate naturally
to guide later revegetation of mined areas.
Upon decommissioning a wellfield, wells are sealed and capped, pipes
are removed and the surface revegetated progressively. At the end of the
mine's life, process facilities will be removed and after discussion
with the stakeholders the land can revert to its previous uses.
Heathgate has provided financial guarantees to the state government in
respect to ongoing mine site rehabilitation up to the final completion
of mining.
Honeymoon
The Honeymoon mine in South Australia was commissioned in 2011 with 340 t/yr U3O8
capacity. The deposit itself was discovered in 1972, about 75
kilometres north west of Broken Hill, 30 kilometres inside South
Australia. MIM Holdings Ltd bought out CSR Ltd's 34.3% share in 1988.
The Honeymoon - East Kalkaroo deposit occurs in porous sand of the
Yarramba palaeochannel at a depth of 100-120 metres and extending over
about 150 hectares. Plans were developed in the late 1970s to extract
the uranium oxide by in situ leaching (ISL), and some $12 million was
spent in preparation. Draft and Final Environmental Impact Statements
were produced, and both South Australian and Commonwealth environmental
approval was subsequently obtained in 1981 for production to 450 t/yr U3O8.
Field tests of the ISL process were carried out and a $3.5 million, 110
t/yr pilot plant was built, but the project was abandoned in 1983.
In 1997 Sedimentary Holdings NL reached agreement with MIM to acquire
the Honeymoon leases next to its own East Kalkaroo deposit on the
Yarramba palaeochannel. The 1997 agreement also included acquisition of
the Gould Dam-Billaroo West leases 75 km northwest of Honeymoon. The
1997 agreement initially brought together known uranium resources of
about 4200 tonnes U3O8 averaging 0.11% and amenable to in-situ leaching.
The purchase was funded by Southern Cross Resources Inc. of Toronto.
Sedimentary Holdings progressively reduced its share in Southern Cross
and sold the last 7% in September 2004.

Field leach trials using the refurbished process plant resumed in 1998 and led to a proposal to produce about 1000 t/yr U3O8 equivalent
(as uranium peroxide) at low cost. A June 2000 draft EIS covered the
Honeymoon - East Kalkaroo deposits on five Mineral Claims and approval
of this was granted in November 2001.
Further drilling and logging with a prompt fission neutron (PFN) tool
in 2004 confirmed high-grade resources which were reported in terms of
grade thickness (GT) – average grade U3O8 multiplied by thickness of leachable sand holding the uranium. In the Honeymoon deposit itself 3300 t U3O8 at an average GT of 0.84 m% was confirmed, with 900 t U3O8 at
an average GT of 0.38 m% in East Kalkaroo adjacent. The program failed
to extend these resources, and further drilling and logging of nearby
parts of the Yarramba palaeochannel immediately NW of Honeymoon in 2004
failed to confirm further resources.
In 2004 the company revised development plans down to a 400 tpa plant
at Honeymoon, but development was deferred pending the outcome of
further exploration at Gould's Dam. In December 2005 Southern Cross
Resources was taken over by Aflease to form sxr Uranium One Inc. (The
'sxr' was later dropped.) Following a new feasibility study, in August
2006 Uranium One announced that development of Honeymoon would proceed
as a 400 t/yr ISL mine. It quoted indicated resources then of 2900
tonnes U3O8 at 0.24% (av grade thickness 0.42 m%)
excluding some thin low-grade material included in earlier estimates.
The adjacent East Kalkaroo deposit had 900 tonnes at 0.074% grade. In
January 2007 a ten-year export permit was granted.
In October 2008 Uranium One announced a joint venture with Mitsui
(49%) to complete development of the project, with Mitsui paying $104
million towards the eventual $138 million cost. Similar joint ventures
with Mitsui would apply to Gould Dam and Billeroo. In May 2012 Mitsui
announced that it was withdrawing from the project. The parties
negotiated the terms of Mitsui's withdrawal, regulatory approval was
given during the third quarter of 2012, and Uranium One "recognised a
gain of $17.2 million as a result of the transaction".
In December 2008 Uranium One announced an engineering, procurement,
and construction management contract with Ausenco Ltd to build the mine.
Total capital cost envisaged was A$ 118 million, including pulsed
column solvent extraction circuit. A mine life of six years (including
ramp-up) was expected. In 2011 capital expenditure of about $20 million
comprised $10 million for wellfield development and $10 million for
other construction activities and fixed asset purchases. Estimated
capital expenditure for 2012 was $25 million.
Production: First production was in September 2011, with 45.4 t produced in 2011, and a ramp up to 400 t/yr U3O8 was planned. Production in 2012 was expected to be 275 tonnes U3O8,
at $47/lb – much more than the company's average cost of production in
Kazakhstan, but commissioning was drawn out and resulted in only 155t
production. In 2013 production was 112 tonnes U3O8. Mitsui's A$ 104 million largely funded the commissioning. A February 2012 report quoted reserves of 2890 tonnes U3O8 at 0.08% and indicated resources of 5400 tonnes U3O8 at 0.129%.
Since 2009, 51.4% of Uranium One has been owned by Russia's ARMZ, but
in 2012 ARMZ moved to buy out all the other shareholders. It now has
full ownership. In November 2013 the company said it had “impaired the
Honeymoon project due to continuing difficulties in the production
process and issues in attaining design capacity, combined with high mine
operation costs. The carrying value of Honeymoon was therefore written
down by $67.8 million.” A week later it was announced that the mine
would be closed pending improved uranium markets and put on a care and
maintenance basis. Production ceased by the end of 2013.
