Capital mining owns the Mundaerno uranium property in South Australia, among other gold, base metals, and platinum exploration assets.

Exploration tenements near Honeymoon mine awarded to Russian state-owned company, in spite of current uranium export ban to Russia

A Russian state-owned nuclear energy company, Rosatom State Atomic Energy Corp, has secured the rights to exploration tenements near its mothballed Honeymoon uranium mine in northern South Australia even though Prime Minister Tony Abbott banned uranium sales to Russia during a diplomatic stoush last year.
Honeymoon has been through a series of ownership changes. It is now 100 per cent owned by a subsidiary of Rosatom, Uranium One, which has just been awarded exploration tenements near the Honeymoon mine by SA authorities in a competitive tender. About eight other local companies were advised by letter late last week they had been unsuccessful in the tender. Mr Abbott last September banned future uranium sales to Russia over its backing of pro-Russia rebels fighting in eastern Ukraine. Uranium One has kept the Honeymoon mine, about 75 kilometres north-west of Broken Hill, shut for the past 15 months because of low uranium prices and some operational problems.

South Korea begins uranium exploration in South Australia

The South Korean government has begun to invest in the exploration of uranium in Australia. The Koreans have formed a joint venture with Cauldron Energy , a Western Australian company, which is exploring for low grade uranium in the far north of South Australia.
The Marree Project, located 550 kilometres north of Adelaide comprises five exploration licences covering over 2500 km in the Eromanga Basin. The Korean consortium is a make up of governemnt owned Korea Resources Corporation with Daewoo and LG International. (ABC Jan. 2, 2013)


Opening of Woomera weapons test range to mining

Australian parliament passes bill to open Woomera weapons test range to mining: The South Australian Government has welcomed the passage of federal legislation freeing up the potential mineral resources in the Woomera Prohibited Area. The defence zone covers 127,000 square kilometres and Geoscience Australia thinks it contains 62 per cent of known copper and 78 per cent of known uranium resources in Australia. The legislation passed by Federal Parliament this week will create a regulatory framework for access to the zone, although defence will remain a primary user. (ABC July 17, 2014)

South Australia in talks to open Woomera weapons test range for uranium mining: South Australian Mineral Resources and Energy Minister Tom Koutsantonis on Tuesday that the state was working with the federal government to open up the Woomera prohibited area (WPA) for exploration and mining. Occupying some 127,000 km2, the WPA is mainly pastoral country used for weapons tests, rocket launches and other experimental programmes. Koutsantonis said that the area within and directly adjacent to the WPA is estimated to contain around 78% of the nation's uranium resources, and some 62% of Australia's known copper resources. (Mining Weekly Feb. 28, 2012)

Plan opens Woomera defence zone to mining: A plan has been finalised to open up the vast Woomera Prohibited Area in the outback to mining projects. A review of management options for the area has concluded there is potential for more than A$35 billion of mining development over the next decade, including iron ore, gold and uranium projects. The plan leaves defence as the primary user of the area in outback South Australia and would create zones to allow access for other interests. Defence Minister Stephen Smith says it is in the national interest to change the access to Woomera.
About two years ago, the Federal Government cited national security as a reason for blocking a joint venture between Western Plains Resources and a Chinese company. The [iron] ore deposit was in the Woomera Prohibited Area. (ABC May 3, 2011)


South Australian Premier rules out uranium mine at Myponga Reservoir

South Australian Premier Mike Rann has issued a statement ruling out uranium mining near the Myponga Reservoir; his Cabinet would never approve a uranium mine anywhere near the Myponga Reservoir and there will be no uranium mining established near the reservoir while he is Premier. Exploration company Marathon Resources wants to conduct soil tests near Yankallila on the Fleurieu Peninsula to explore for minerals. (ABC Oct. 2, 2006)
On Nov. 29, 2006, Marathon Resources announced to relinquish the exploration licence at Myponga.

South Australia's ALP blocks new uranium mines in the State

On Oct. 9, 2005, a South Australian Labor Party conference strengthened opposition to expanding uranium mining. The conference endorsed, unanimously and without debate, a platform motion that says: "Labor continues to be opposed to the establishment of any new uranium mines and any expansion into the enrichment process." The platform binds an ALP state government until 2010.
Australian Conservation Foundation nuclear campaigner David Noonan now called on the South Australian Government to stop subsidising exploration for uranium, saying this policy - which gives some explorers a 50 per cent rebate on drilling costs - was a waste of public resources, in light of the ALP platform. (Australian Oct. 11, 2005)

Marathon Resources withdraws from uranium business, penalized and sorely tried

Minerals exploration company Marathon Resources has turned its back on the uranium industry for good. The company says its experience suggests the "risks were more likely to exceed rewards" in a sector hit by low ore prices. "Both the political and regulatory regimes have deterred us permanently from the uranium industry," chairman Peter Williams told the company's annual meeting in Adelaide on Thursday (Nov. 21).
Marathon previously has been involved in exploring a section of South Australia's Flinders Ranges with a view to developing a significant uranium deposit. However, it fell foul of the South Australian government over the disposal of waste while the government eventually moved to ban all mining in the environmentally-sensitive area anyway. (Canberra Times Nov. 21, 2013)

Fate of drilling waste from former uranium exploration in Arkaroola wilderness sanctuary still unclear

It's the nuclear-waste facility that few people know about - 21 barrels of medium- to high-level radioactive material stored in a tin shed in South Australia's Outback paradise. The waste is in the heart of Arkaroola, the Outback wilderness sanctuary the State Government hopes will one day be included on the World Heritage list. The facility, known as Painter Camp, is not registered under the Radiation Protection Act and a management plan for its safe and secure operation is still being developed.
In a revelation likely to outrage environmental groups and anti-nuclear campaigners, responsibility for Painter Camp now lies with the State Government, which a decade ago took its fight against the construction of a national radioactive waste depository in our Outback to the High Court. An EPA spokesperson said DMITRE has applied to have the facility, which sits in a gully in the shadows of uranium-rich Mt Gee and Arkaroola's famed Ridge Top Track, registered under the Radiation Protection Act. The EPA did not elaborate on the radiation levels of the materials, however, it is known radiation levels of the materials stored inside the barrels were too high for it to be returned to the ground during a rectification clean-up Marathon was ordered to take by the EPA in 2009. Most of the barrels now in the shed had been buried by Marathon as a way of disposing of them. (The Australian Dec. 25, 2012)

Marathon Resources' exploration licence in Arkaroola wilderness sanctuary reinstated after three year suspension for improper waste disposal; protests in Adelaide

In February 2011 the Minister renewed exploration licence EL4355. (PIRSA Feb. 7, 2011)
About 40 people gathered outside Parliament House in Adelaide on Monday (Feb. 7) to protest on news of renewal of the exploration licence. (ABC Feb. 7, 2011)

Marathon Resources to obtain new exploration licence in Arkaroola wilderness sanctuary

The State Government has announced it intends to renew Marathon Resources' exploration licence for one year, half the period sought by the company. Marathon was ordered to suspend drilling two years ago after it was found to have breached waste disposal conditions by burying waste at the mine site. The discovery of drilling core samples and other waste buried at the mine site in 2008 sparked a formal investigation.
Acting Mineral Resources Development Minister Jack Snelling said the Government would now hold discussions about new oversight with the company before granting exploration rights. The concession comes amid calls for a complete mining ban in Arkaroola due to biodiversity and environmental concerns. (Adelaide Now Dec. 20, 2010)

New frog species found at Mount Gee uranium exploration site

The owner of Arkaroola Wilderness Sanctuary says discovery of a new frog species is yet another reason to be wary of mining in the Flinders Ranges region of outback South Australia. Scientists say it is the first new species to be identified in SA in 45 years. The species was found this month at Arkaroola, where Marathon Resources is involved in a uranium exploration project at Mount Gee. Sanctuary owner Marg Sprigg says she is worried Marathon's initial drilling program could lead to it getting a full drilling licence later in the year. "I'm a geologist, I'm not against mining but I don't think you have to mine everywhere and there were a lot of geologists who put in submissions saying 'leave Arkaroola alone, it is too special, it's a brilliant geological teaching laboratory'." Ms Sprigg says mining could prevent more unique species being found in the Flinders Ranges. (ABC June 16, 2010)

Marathon Resources penalized upon contamination probe at Mount Gee uranium exploration site

A clean-up plan has been approved by the South Australian Government for a mining company caught dumping waste in Arkaroola Wilderness Sanctuary in the Flinders Ranges. Marathon Resources was forced to stop drilling in the wilderness area early this year after it was found to have breached sections of its uranium exploration licence by burying waste last year. It was ordered by the SA Government to clean up about 35 tonnes of waste buried in plastic and calico bags. The Department of Primary Industries and Resources has now formally approved Marathon's clean-up plan. (ABC Aug. 12, 2008)

The Government of South Australia suspended Marathon Resources exploration drilling operations at Mt Gee indefinitely for Exploration Licence EL3258 in February 2008. (PIRSA)

A uranium explorer which wrongly disposed of drill samples at an outback wilderness site has had its operations suspended indefinitely. Marathon Resources had been under investigation by the South Australian Government and police over work at its Mount Gee deposit in the Arkaroola wilderness sanctuary of the Flinders Ranges. SA Premier Mike Rann says the incorrect disposal of waste at the site was a significant breach of the company's exploration licence. The SA Government has told the mining company it will have to clean up the site and satisfy other conditions before it will be allowed to resume work. Police were called in to investigate in December when bags of drilling samples were found buried just below the surface. Marathon Resources chairman Peter Williams says the waste was wrongly buried at its exploration site in 2006. (ABC Feb. 12, 2008)

Alleged environmental contamination at the Mount Gee uranium deposit in the far north of South Australia are being investigated by SA Government and the Environment Protection Authority (EPA). Police have reported alleged contamination at drilling holes on the site. Marathon Resources is alleged to have wrongly disposed of resource samples at the site. (ABC Jan. 16, 2008)

Pre Feasibility Study and Environmental Impact Study commissioned for proposed Mt Gee uranium mine

On Dec. 18, 2007, Marathon Resources Ltd announced it had given the go-ahead for both a Pre Feasibility Study (PFS) and Environmental Impact Study (EIS) to begin.
"The purpose of the PFS is to cost the technical viability of underground extraction of uranium ore to a near-site processing facility," Marathon Director, Mr Denis Wood, said. On April 3, 2007, the company had announced the interim scoping report indicated the viability of an underground operation targeting a production rate of over 1,000 tonnes of U3O8 [848 t U] per year. The PFS is expected to be completed by March 2009.
Environmental issues that form part of the EIS include groundwater impacts, surface water management, flora and fauna, Aboriginal heritage management, air and noise quality, and land use impacts. The EIS is expected to take 12 to 18 months to be completed.

Commissioning of Australia's fourth uranium mine begins next month. The start to the long process should result in first production before the end of the year from the A$138 million Honeymoon project in South Australia, a joint venture between Canada's Uranium One (51 per cent interest) and Japan's Mitsui & Co (49 per cent). (The Age March 12, 2010)

Construction has begun on South Australia's third uranium mine. Preparatory work at the Honeymoon project in the state's far north-east will continue until the middle of next year, with mining to start after that. (ABC April 24, 2009)

On Dec. 12, 2008, Ausenco Limited announced that it has signed a deal with Uranium One Australia to use its engineering procurement and construction management services on Uranium One's Honeymoon uranium project in South Australia. The remaining development of the Honeymoon project would involve capital investment in the order of A$70 million to A$80 million. The contract award follows the completion of the initial feasibility study; technical reviews and engineering program completed earlier this year. Ausenco said the Honeymoon project was expected to produce about 880,000 pounds of U3O8 [338 t U] per year and the transition to this phase followed the successful entry into a joint venture by Uranium One with Mitsui.

On Oct. 15, 2008, Mitsui & Co Ltd said it has agreed to buy a 49% stake in six uranium deposits in South Australia from Uranium One Inc. Mitsui projected to spend A$104 million ($73 million) in the purchase and development of the deposits. One of the blocks, Honeymoon project, is expected to start commercial production in end-2009 or 2010, with annual production of 400 tonnes, for a production period of six years. (Reuters Oct 15, 2008)

On May 15, 2008, Uranium One announced it has decided to suspend development activities at Honeymoon "to allow for evaluation of corporate development opportunities for the project". The Corporation's production guidance for 2009 had previously included 600,000 pounds of U3O8 [231 t U] expected to be produced from Honeymoon.

Uranium One has received full approval for its mining operations at the Honeymoon mine, north of Olary in far north South Australia. The South Australian Government approved the company's mining and rehabilitation program 10 days ago, and now the state Environmental Protection Agency (EPA) has given its approval to the mine's radioactive waste management plan and radiation management plan. Approval comes with several stipulations and marks the beginning of mine construction, although the company will again go under review before production begins. (ABC Jan. 21, 2008)

During a public meeting held on August 7, 1998, Heathgate's project manager was forced to concede a spill that had occured on March 12 at the Beverley trial site. The uranium-bearing solution had escaped as a fine spray following the rupture of a pipeline carrying sulphuric acid uranium solution from extraction wells to the processing plant. ``It is estimated that the total loss was less than 500 litres over an area of about 50 square metres,'' he said. The contaminated site had been cordoned off – not cleaned up. (Reuters, Aug. 7 / The Australian, Aug. 8, 1998)

The new Environmental Impact Statement for the proposed Beverley uranium mine was released for public comment by Heathgate Resources Pty Ltd on June 29, 1998.
The Supplementary EIS has been released on Oct. 3, 1998.

The Final Guidelines for an Environmental Impact Statement on the proposed development of the Beverley Uranium Project were released in March 1998.

For details of the environmental assessment process, see the Australian Environmental Protection Agency Environment Assessment Branch notifications on the Beverley uranium mining project .

"At the Uranium'98 Conference, Heathgate Resources announced that the project's resources were almost doubled to 21,000t U3O8 at 0.18%, accessible by in-situ leaching. The current field trial is surpassing expectations. It consists of a 25m x 25m quincunx pattern of 4 injection wells and one production well with pump, delivering 75kg U3O8 per day to the pilot plant. Subject to its EIS and other approvals, production at 900 t/yr could begin in mid 1999." [UIC Weekly News Summary, 13 Feb 1998]

"A $5 million, 4-12 month field leach trial has begun at the Beverley uranium prospect in northern South Australia. The trial, using weak acid solution with oxygen, was approved by state authorities as part of the environmental impact assessment. Four injection wells and a single extraction well are involved. The pH of the aquifer will be lowered from 6.3 to about 3.5.
If the EIS is approved, Heathgate Resources will construct a $25 million wellfield and plant to produce 900 tonnes of uranium oxide per year by in situ leaching. Some 11,000 tonnes of uranium is contained in ore over an area of 4 km x 500 m, within a highly saline, radioactive aquifer at 110-140 metres depth.
From mid January, some 30-50 kg/day of U3O8 is being recovered in a small plant as a by-product of the trial. It remains the property of the SA government." [UIC Weekly News Summary, 9 Jan 1998]

The Bevereley uranium prospect in South Australia, owned by General Atomics of USA, is being proposed for development within three years. It would be an in-situ leach operation, with 6 Mt grading 0.27% U3O8 (16,200 t) resources, making it the largest Australian deposit of its kind. [UIC Weekly News Summary, 14 Feb 1997]

Construction commences at Beverley Four Mile uranium in situ leach project: On Dec. 3, 2013, Alliance Resources Ltd announced that it has received notice from Quasar Resources Pty Ltd advising that construction at the Four Mile project has begun.

Beverley Four Mile ISL project obtains final federal environmental approval: South Australia's next uranium mine in the Flinders Ranges has cleared its final regulatory hurdle, receiving Commonwealth Government environmental clearance. The mine monitoring, closure and community engagement plans required under the Commonwealth Environmental Protection and Biodiversity Conservation Act had been approved, Alliance Resources said.
The State Government last month approved its Program for Environment Protection and Rehabilitation (PEPR) which covers the safe environmental management of the mine during operation and its rehabilitation once mining is over. In addition to the PEPR, the Environment Protection Authority (EPA) has also approved a Licence for Mining and Mineral Procession at Four Mile, including Radiation Management and Radioactive Waste Management plans.
The project now has to submit modifications to existing PEPR at operations in Beverley and Beverley North to accommodate the integration of the Four Mile operations and pay a Rehabilitation Liability Bond. (news.com.au Sep. 3, 2013)

Beverley Four Mile ISL project obtains final state environmental approval: A new uranium mine in South Australia's north has been given the go ahead by the state government.

Decision to recommence development of Four Mile uranium in situ leach project: On Oct. 24, 2012, Alliance Resources Limited announced that a decision to recommence development of the Four Mile Project was made today with Quasar Resources Pty Ltd voting its 75% interest in favour and Alliance Craton Explorer Pty Ltd voting its 25% interest against Quasar's proposed Start-Up Plan.
The Start-Up Plan comprises: uranium capture at Heathgate Resources Pty Ltd's Pannikan satellite plant with elution, precipitation, drying and packing at Heathgate's Beverley processing plant; in-situ recovery (ISR) mining operations commencing at Four Mile East in Q2 2013 and at Four Mile West in Q4 2013, and first uranium sales are scheduled for Q3 2013.

Litigation on Four Mile uranium project settled: The junior partner in Four Mile, the ASX-listed Alliance Resources (25%), yesterday revealed that long-running litigation with its joint venture partner, US group Heathgate (75%) - has been settled. The terms of the settlement are confidential but are expected to clear the way for the long-delayed project to be developed.
Four Mile was meant to start production in April this year after winning clearance from then federal Environment Minister Peter Garrett in July last year. (Sydney Morning Herald Dec. 6, 2011)

Uranium developer Alliance Resources on Monday (Apr. 18) warned shareholders that the capital cost for its proposed Four Mile uranium project, in South Australia, could increase by as much as 25%.
The increase to the project cost was based on a new five-million pound a year stand alone in-situ recover (ISR) and uranium plant for the Four Mile project, taking the entire capital cost to around A$210.1-million, from the original estimate of A$168-million.
The increase in the capital cost estimates of the optimisation study compared with the previous scoping study estimates for the five-million pound a year processing plant, and was owing to the increases in the estimates for well fields, equipment and engineering, processing, construction and maintenance, as well as electrical works. (Mining Weekly Apr. 18, 2011)

Alliance Resources is investigating building a $168 million uranium processing plant at Four Mile, as the stalemate between the project's joint venture parties shows no sign of resolution. The announcement comes as Alliance launches further legal action against Quasar and affiliate Heathgate, accusing it of misleading practices under the Trade Practices Act. The two parties had been developing a $110 million uranium mine near Beverley, which was expected to be in production this year as the state's next major mine. The new mine was to be a "satellite" operation connected to the Heathgate-owned Beverley uranium mine, but last year the development was shelved because of a legal dispute over native title registration. (Adelaide Now July 20, 2010)

Court to review Federal approval of Beverley Four Mile ISL uranium mine: On Dec. 11, 2009, Alliance Resources Ltd announced that proceedings have been commenced in the Federal Court of Australia (Sydney Registry) by Alan Oshlack of the Indigenous Justice Advocacy Network seeking a review of Federal Minister Peter Garrett's decision in July 2009 to grant environmental approval for the Four Mile Project. (ABC Dec. 11, 2009)

On Sep. 21, 2009, Alliance Resources Limited announced that the schedule for commissioning of the Four Mile Uranium Project in South Australia has been delayed to April 2010 or beyond. The delay is due to the inability of joint venture partner and manager Quasar Resources Pty Ltd to begin on-site construction at Four Mile and placing project development activities on hold due to a delay in the grant of a mining lease. The offer of a mining lease by PIRSA is pending registration of the Native Title Mining Agreement (NTMA) covering the Four Mile uranium mine.

Uranium mining in the far north of South Australia at the Beverley location near Arkaroola Wilderness Resort is being openly challenged by Aboriginal Traditional Owner Mrs Enice Marsh. She is concerned that the new Beverly Four Mile uranium mine is destroying sacred sites, polluting the environment unnecessarily, and promoting a culture of bullying. "If mining continues to expand it will be a total disaster all round: what will happen to the land, the water, the bush tucker and the animals?" she said. "There's no independent monitoring up there," Mrs Marsh said and "the mine only has a life expectancy of eight to ten years but would leave a legacy of damage for generations to come." "Native Title has failed to protect our sites and the governing body that should be representing the interests of the whole community is failing in its duty of care." (Flinders News Aug. 21, 2009)

The chairman of the Adnyamathanha Traditional Land Association says the Four Mile Mine was inevitable and Aboriginal people have been disempowered. Vince Coulthard says the Adnyamathanha people have entered into an agreement with the developer Quasar, which gives some positive outcomes fo the community - unlike previous developments. He says many of his people are deeply hurt about the development but says it is out of their control. "Well I think people have come to the understanding that if they didn't support it- it's going to happen [in] any case so the best thing to do is to negotiate an agreement," he said. (ABC July 17, 2009)

Aboriginal elders want the federal government to defer its decision on a new Four Mile uranium mine in South Australia until an independent Aboriginal heritage investigation is completed. Adnyamathanha (Adnyamathanha) elders, who are the traditional owners of the land where the new mine is be to established, say the approval is in breach of regulations governing Aboriginal heritage protection. (SBS July 15, 2009)

Federal Environment Minister Peter Garrett has given the go ahead for the operation of the Four Mile uranium mine, near the existing Beverley mine. Mr Garrett says waste from the mine will be processed at the existing Beverley mine. (ABC July 14, 2009)

On Jan. 8, 2009, PIRSA released the Beverley Four Mile Project Mining Lease Proposal for public comment.
The Beverley Four Mile Project entails construction of a satellite facility on Heathgate's existing Beverley mining lease, close to the Four Mile deposits, and construction of in-site recovery (ISR) wellfields of the same design as currently used on the Beverley mining lease. This satellite facility would remove the uranium from the ISR liquor by physical means, producing uranium bearing resin, which would be trucked to the Beverley processing plant. The resin would then be stripped of uranium, and trucked back to the satellite facility.
Minor modifications would be required at the Beverley processing plant to accept the uranium-bearing resin, however there would be no net increase in uranium processing capacity. The uranium stripped from the resin would be processed at Beverley, and the small quantity of liquid waste arising would be disposed of at Beverley.
Please respond by 20 February 2009 with any factors that should be considered in the assessment of this application.

On Sep. 25, 2008, Alliance Resources Ltd announced the decision to mine the Four Mile deposit by in-situ leaching. Uranium concentrate production is proposed to commence in January 2010, ramping up to 3 million lbs U3O8 [1,154 t U] per annum within three months. It is proposed to construct a satellite pre-processing plant close to the Four Mile deposits to recover uranium from ISL mining solutions for transport to the existing Beverley uranium processing facility for further processing, drying and packaging of uranium concentrate.

Traditional owners back more uranium mining: The chairman of the Adnyamathana Traditional Lands Association says he will support greater mining of uranium on his community's land. An affiliate of Heathgate Resources, Quasar, lodged an application last month for a mining lease just north of the Beverley uranium mine in outback South Australia. Vince Coulthard says while all the traditional Land is sacred, he must note the benefits from mining. (ABC June 25, 2008)

A native title applicant for the land surrounding the Four Mile uranium deposit in South Australia says she will not sign off on any agreement for mining to start. A member of the Adnyamathana community, Gillian Anderson, says she is seeking legal advice to help prevent what she describes as a devastation of sacred land. Ms Anderson has already been taken to court for not signing a lease for an extension of Heathgate's Beverley mine and says she will take the matter to court if necessary. But the Adnyamathanha Traditional Lands Association say it is happy with the benefits the mines bring for its community. (ABC May 27, 2008)

An application has been lodged by Quasar Resources Pty Ltd, an affiliate of Beverley operator Heathgate Resources, to develop the Four Mile uranium deposit in South Australia. The mine at Four Mile would be about 10 kilometres north-west of the Beverley mine and use the same processing facilities. It is planned to be working by 2010 and employ 200 people. (The Age May 19, 2008)

On Apr. 28, 2008, Alliance Resources Ltd announced that project manager Quasar Resources is now planning to apply for a Mining Lease rather than a Retention Lease over the Four Mile project. A feasibility study consisting of the establishment of a mineral resource estimate at Four Mile East, and positive outcomes of hydrological and metallurgical studies, are anticipated to make redundant the previously planned field leach trial. This decision means that First Stage Mining at Four Mile is now scheduled to commence after grant of the Mining Lease (anticipated to be late 2009).

On Jan. 16, 2008, Alliance Resources Ltd announced the results of a Concept Evaluation Study for the Four Mile in-situ leach project. Uranium concentrate production is proposed to commence in 2010, at a projected start-up capacity of 1.5 Mlb [577 t U] per year, potentially increasing up to 4.5 Mlb [1731 t U] per year production capacity. A Field Leach Trial is scheduled to commence in June Quarter 2008 to assess the use of ISL at the Four Mile Project.

Pastoralists concerned about field leach trial at proposed Samphire acid in situ leach uranium mine

Alligator Energy plans to undertake a trial on a pastoral station south of Whyalla to measure the feasibility of a uranium mine.
The process would involve combining sulphuric acid with groundwater to dissolve the uranium and then pump it back up to the surface, a process that the company said would not be environmentally harmful.
Mullaquana Station is near the trial site, and pastoralist Tom Joyce said he was worried about the potential for groundwater contamination. "The first initial concerns are what that looks like environmentally for us as landowners, as residents, and what that looks like environmentally for our region and ultimately for the Spencer Gulf," he said.
Nearby pastoralist Eric Ashby said he was also worried about what effect the acid could have on the environment. (ABC Feb. 24, 2023)

On Feb. 20, 2023, Alligator Energy Limited had announced that extensional, resource upgrade and groundwater monitoring well drilling [in preparation for the planned Field Recovery Trial later this year] has recommenced at the Blackbush Deposit, Samphire Uranium Project south of Whyalla, South Australia.
