Ravensthorpe cost BHP Billiton US$2.2 billion to build but led to $3.6 billion in write-downs when it was shut down in January 2009, after less than a year of operation. The closure caused considerable bad publicity for the owner, prompting the operation to be placed on the market. The mine was sold in December 2009 to First Quantum Minerals for US$340 million.
First Quantum Minerals successfully returned the operation to commercial production in December 2011, after 18 months of modifications and re-commissioning. Following a period of low nickel prices, the operation was placed on care and maintenance in October 2017, with the loss of 270 local jobs.
Mining in Ravensthorpe considerably predates the current nickel mine, with gold discoveries dating back to 1898. The town experienced a down turn after the First World War but mining for copper continued up until the 1970s. A railway line connected Ravensthorpe with the port of Hopetoun from 1901 to 1925, when the line was closed.
The project was approved in 2004 and construction commenced shortly afterward. The plant known as the Ravensthorpe Nickel Project was commissioned in late 2007 with first production occurring in October and the first 5,000 tonnes being produced by December 2007. The plant was officially opened in 2008, after massive cost blow outs and delays. Production was expected to total 50,000 tonnes of nickel per year.
In January 2009, BHP Billiton announced that it was suspending production at Ravensthorpe Nickel Operations indefinitely, due to the reduction in world nickel prices caused by the global economic crisis. The decision cut 1,800 jobs and was expected to have a major impact on the local economy. Nickel prices, having reached a high of US$50,000 per tonne in May 2007, had fallen to under $11,000 per tonne by the time of the mines closure. The closure had a devastating effect on the local communities of Ravensthorpe and Hopetoun and led to BHP Billiton being heavily criticised for its handling of the closure.
On 9 December 2009, BHP Billiton sold the operation to Vancouver-based First Quantum Minerals for US$340 million. First Quantum was one of three bidders for the mine and actually produced the lowest offer. First Quantum won the bid despite offers from Minara Resources at US$360 million and Poseidon Nickel at US$400 million being higher than theirs. BHP Billiton said that the lower price was accepted due to fewer conditions being imposed by the tenderer. First Quantum announced the completion of the acquisition on 10 February 2010.
Modifications and recommissioning
First Quantum Minerals spent eighteen months implementing extensive modifications to improve the mineral processing at the front end of the plant, through the construction of two new ore crushers, new product storage ponds and a new dewatering facility. Recommissioning began in the second quarter of 2011, with first nickel produced in October 2011. Problems BHP faced in the crushing, beneficiation and rejects plants were successfully resolved.
First Quantum expected an annual production of 39,000 tonnes of nickel for the first five years of production and an average of 28,000 tonnes per year for the mine's projected lifetime of 32 years. The operation was placed on care and maintenance in October 2017 due to sustained nickel prices below the cost of production.
Commercial production by First Quantum Minerals was achieved on 28 December 2011. The operation produced 32,884 tonnes of nickel in its first full year of operation in 2012. BHP Billiton, by comparison, produced 14,000 tonnes of nickel from the operation in the nine months the plant operated from its opening in May 2009 before it was mothballed.
In the last full year of operation (2016) the mine produced 23,624 contained tonnes of nickel (17,630 payable tonnes) at a cash cost of US$4.66 per lb (total cost of US$6.34 per lb). The average LME nickel price for 2016 was US$4.36 per lb. Production for 2015 was 26,667 contained tonnes (20,567 payable tonnes) of nickel.
