January 15, 2024 - First Quantum Minerals (FQM) will reduce its operating activities at Ravensthorpe Nickel Operation (RNO) with suspension of mining operations at the Shoemaker Levy ore body and bypassing the high-pressure acid leach (HPAL) circuit. Existing ore stockpiles will continue to be processed through the Atmospheric Leach circuit providing significant mining and processing cost reductions. This new operating model represents a three-year plan under which RNO will maintain production of nickel concentrate from ore stockpiles before recommencing mining activities at Hale Bopp and Halley’s ore bodies. The three-year plan represents the anticipated period for weaker nickel prices. The decision results from the significant downturn in the nickel price experienced during 2023, combined with currently higher operating costs in Western Australia, and a requirement to improve the financial viability of RNO at current nickel prices. The cessation of mining and associated processing activities at RNO will reduce the company’s directly employed workforce at the site by approximately 30%, with contractors to be redeployed by their employers. RNO General Manager Scott Whitehead said reducing the mine’s operating activities for a sustained period was the best decision for the company, workforce and local region. “Transitioning to a new operating model will allow us to continue to produce and export our nickel product, which is a critical mineral and has a lower carbon footprint than other suppliers. The operational changes will ensure RNO remains viable longer term and we will retain most of our residential and FIFO workforce, thereby supporting the communities of Hopetoun and Ravensthorpe and providing income for the region and Western Australia,” Mr. Whitehead said. “It’s important we position ourselves to respond in a timely manner to future improvements in the nickel price by being able to reactivate our mining activities at the preferred time.” RNO will remain a significant local nickel concentrate exporter, expecting to produce on average approximately 16,000 contained tonnes per annum over the next three years. RNO produces an ESG-focused, compliant battery grade nickel which is in the lowest quartile of CO2 emissions globally and will be increasingly critical to industries and consumers in the United States and European Union as part of the transition to a decarbonized economy. November 19, 2021 - First Quantum Minerals (FQM) has officially opened the Shoemaker-Levy mine at its Ravensthorpe nickel-cobalt operations in Western Australia, extending the operation’s life by 20 years. Ravensthorpe produced 4248 tonnes of nickel for the September quarter while commissioning continued at Shoemaker-Levy, in time for the new mine’s official opening by Western Australia Mines and Petroleum Minister Bill Johnston. “Congratulations to FQM on the opening of the new Shoemaker-Levy mine,” Johnston said. “Ravensthorpe has felt the impact of a volatile nickel market in previous years but since 2020 nickel prices have trended upwards because of the increasing global production of batteries. “This new mine will add decades to the life of this rejuvenated operation, securing jobs and strengthening the McGowan Government’s vision for WA’s future battery industry strategy.” Previously, Ravensthorpe had 10 years of operation remaining, but the addition of Shoemaker-Levy should now see the mine operate until about 2050. First Quantum acquired the decommissioned mine from BHP in 2010 for $US340 million (then worth about $A370 million) and shipped first nickel concentrate in November 2011. By 2017 the mine was put on care and maintenance to manage lowly nickel prices, before being restarted once more in 2020. Since its restart in 2011, Ravensthorpe has sold 202,782 tonnes of nickel and 7527 tonnes of cobalt. The mine currently employs 650 people with no announcement to date on how the new mine will be staffed. Earlier in 2021, Korean steel-making company POSCO acquired a 30 per cent share of the Ravensthorpe operations for $US240 million ($310 million), outlining just how much value First Quantum acquired from its deal with BHP. As part of the deal, POSCO will be provided with a long-term offtake agreement for 7500 tonnes of nickel in mixed nickel-cobalt hydroxide precipitate (MHP) per year from 2024. Outside of steel production, POSCO is a leading integrated producer of cathode and anode materials for the electric vehicle (EV) battery sector. Following the deal in May, First Quantum chairman and chief executive officer Philip Pascall welcomed POSCO as a new long-term strategic partner in Ravensthorpe. “Our respective organisations have complementary skillsets which will allow us to maximise the strategic value of Ravensthorpe as a key long-term supplier of nickel to the EV battery sector,” he said. August 9, 2017 - Canadian mining giant First Quantum Minerals has announced it will mothball its Ravensthorpe nickel operations in WA's south-east from early next month because of low nickel prices. The Toronto-based company employs about 270 people at the Ravensthorpe mine and the closure will hit the community hard only months after devastating floods ripped through the region. First Quantum said it would cost about $10 million to enter care and maintenance, which should be in effect by early October. The annual bill of maintaining the site is estimated at $5 million. In a statement, First Quantum's chief executive Philip Pascall described the decision as "disappointing". "Ravensthorpe is an excellent operation with an outstanding workforce and supportive community but the continuing depressed nickel market conditions, over some years, leaves us no option," he said. "Over the next few weeks we will work closely with our employees and key contractors to mitigate the impact and manage carefully the staged shutdown of operations. "We will be offering assistance to employees in seeking further employment opportunities." However, there is some hope for the mine, with First Quantum saying it would continue to progress the permitting process at the Shoemaker Levy orebody, along with regular review of the market conditions for a potential restart of operations. To restart operations, should favourable conditions prevail, is estimated at $10 million. The closure comes just weeks after First Quantum posted back-to-back quarterly losses. The company reported a $US18 million loss for the June quarter, following a $US29 million loss in the March quarter. March 12, 2016 - First Quantum Minerals has played down a renewed round of speculation it is preparing to mothball its struggling Ravensthorpe nickel mine, saying it needs to keep it operating to deliver into hedged production. Ravensthorpe’s 300-strong workforce has been preparing for the worst amid talk First Quantum has quit buying critical raw materials needed to keep Ravensthorpe’s massive processing plant running. Multiple sources toldWestBusiness last week Ravensthorpe had not taken delivery of its March shipment of sulphur, heightening concern the nickel operation is running down its stockpiles ahead of a potential closure of the operation. It is understood Ravensthorpe has enough sulphur stockpiled to keep its main high pressure acid leach plant running for at least six weeks, and sources suggest there is enough time for delivery of new supplies if the decision is to continue to operate Ravensthorpe beyond that. A spokesman for the company said yesterday the deferral of the sulphur delivery was due to a planned maintenance shutdown in April. “Ravensthorpe has a major shutdown in April as part of our ongoing and long-term maintenance program on the High Pressure Leach circuit, therefore, as we do every year, we manage our working capital efficiently, particularly big cost items like sulphur,” he said. “The nickel price has improved during March, so we’ve hedged future production, which can only be delivered from Ravensthorpe now that we have announced the sale of our only other nickel producing mine.” December 15, 2014 - Canada's First Quantum Minerals has shut its 38,000-tonnes-per-year Ravensthorpe nickel plant in Australia following an acid spill, which is under investigation. The rupture of a one of several tanks containing sulphuric acid used to leach nickel late on Sunday caused an undetermined amount of the hazardous slurry to spill into a contained area of the plant 550 kilometres (340 miles) southeast of Perth in Western Australia state, company spokesman Dave Coggin said. Coggin could not immediately say if a declaration of force majeure would be invoked protecting First Quantum from interruptions to sales obligations. "The spill resulting from the failure has been contained within the plant's protective bunded area," Coggin said, adding that there were no reports of injuries, with all staff accounted for. Sulphuric acid for the leaching process is produced on site. "The plant is currently shut down and on the basis of information received to date, no adverse environmental effects are anticipated," he said. While all staff have remained on site, no date has been set for a restart, pending the findings of the investigation, according to the spokesman. First Quantum acquired the Ravensthorpe nickel project from BHP Billiton in 2009 and following extensive rehabilitation restarted the operation in 2011. This year, the facility was set to meet it full production target of 38,000 tonnes, according to the spokesman. LME nickel prices were up 0.3 percent on Monday. Any market impact in metals markets from the shutdown is likely to be muted in the short term given a global supply glut of the metal, used mainly in making stainless steel. Near-record inventories of more than 400,000 tonnes are stacked in London Metal Exchange warehouses. BHP continues to produce nickel at an annual rate of close to 100,000 tonnes at its nearby Nickel West operation. Glencore also operates a nickel-making plant in Western Australia, churning out more than 30,000 tonnes a year. Raw nickel produced at the Ravensthorpe site is bought primarily by metals refining companies in China and India.
October 7, 2011 - First Quantum Minerals Ltd said nickel
production is set to resume by the end of 2011 from
February 10, 2010 - First Quantum Minerals Ltd. announced the
finalization of the acquisition of the Ravensthorpe Nickel Operation in
Western Australia following the receipt of the relevant Government
approvals. The acquisition will take effect on February 10, 2010. The
Company is planning to spend the next 12 months constructing two crushing
plants in the modification of the crushing, conveying, stockpile and reclaim
areas of the plant. This is expected to be followed by approximately six
months of commissioning and ramp-up. The capital requirement for the
modification is estimated at approximately US$150 million, depending on
currency exchange rates. December 9, 2009
- Quantum Minerals will spend about $120-million in capital expenditure
(capex) to bring the Ravensthorpe nickel operation in Western Australia back
into production and to ramp up the operation’s production. Chairperson
and CEO Philip Pascall said in a conference call that the company had made
provision to spend about $140-million on the project, thus allowing it to
have $20-million of contingency funding available for the project. BHP
Billiton, which had shut down the Ravensthorpe mine in early January owing
to low nickel prices, which it said made the operation unprofitable, on
Tuesday announced that it would sell the operation to First Quantum for
$340-million. Ravensthorpe is an open pit mine and hydrometallurgical
process plant used to recover nickel and cobalt to produce a mixed nickel
cobalt hydroxide intermediate product. January 29, 2009 January 21, 2009 - BHP
Billiton announced that it will immediately commence the safe ramp down and
indefinite suspension of the Ravensthorpe Nickel Operation (Australia). |
