Rio Tinto commences production of battery-grade lithium from waste rock at a demonstration plant at the Boron mine site in California...

Rio Tinto has taken the next step in scaling up a breakthrough lithium production process developed at Boron. Battery grade lithium has been produced at a demonstration plant set up to recover the critical mineral and extract additional value out of waste piles from over 90 years of mining at the operation.

An initial small-scale trial in 2019 successfully proved the process of roasting and leaching waste rock to recover high grades of lithium.

The demonstration plant has a design capacity of 10 tonnes per year of battery grade lithium. It will be run throughout 2021 to optimise the process and inform Rio Tinto’s feasibility assessment for progressing to a production scale plant with an initial capacity of at least 5,000 tonnes per year, or enough to make batteries for approximately 70,000 electric vehicles.

Rio Tinto Minerals chief executive Sinead Kaufman commented: “This is a valuable next step in scaling up our production of lithium at the Boron site, all from using waste material without the need for further mining. 

“It shows the innovative thinking we are applying across our business to find new ways to meet the demand for emerging commodities like lithium, which are part of the transition to a low-carbon future.”

Rio Tinto’s lithium pipeline includes the Jadar lithium-borate project in Serbia, for which a feasibility study is expected to complete by the end of 2021.

Development of the lithium project at Boron draws on Rio Tinto’s long-standing partnership with the U.S. Department of Energy’s Critical Materials Institute (CMI), which is focussed on discovering ways to economically recover critical mineral by-products from existing refining and smelting processes. CMI experts worked alongside Rio Tinto technical leads to help solve a number of key processing challenges to produce battery grade lithium at Boron.

Vale’s $150mn investment in operations at Thompson, Manitoba will extend mine life by 10 years

Vale has announced a $150mn CAD investment to extend current mining activities in Thompson, Manitoba by 10 years while aggressive exploration drilling of known orebodies holds the promise of mining well past 2040.

Global energy transition is boosting the market for nickel

The Thompson Mine Expansion is a two-phase project. The announcement represents Phase 1 and includes critical infrastructure such as new ventilation raises and fans, increased backfill capacity and additional power distribution. The changes are forecast to improve current production by 30%.

“This is the largest single investment we have made in our Thompson operations in the past two decades,” said Mark Travers, Executive Vice-President for Base Metals with Vale. “It is significant news for our employees, for the Thompson community and for the Province of Manitoba.

“The global movement to electric vehicles, renewable energies and carbon reduction has shone a welcome spotlight on nickel – positioning the metal we mine as a key contributor to a greener future and boosting world demand. We are proud that Thompson can be part of that future and part of the low carbon solution.”

Vale continues drilling program at Manitoba

Coupled with today’s announcement, Vale is continuing an extensive drilling program to further define known orebodies and search for new mineralization.

“This $150mn investment is just one part of our ambitious Thompson turnaround story. It is an indicator of our confidence in a long future for the Thompson operations,” added Dino Otranto, Chief Operating Officer for Vale’s North Atlantic Base Metals operations.

“Active collaboration between our design team, technical services, USW Local 6166, and our entire Thompson workforce has delivered a safe, efficient and fit-for-purpose plan that will enable us to extract the Thompson nickel resources for many years to come.”

The Thompson orebody was first discovered in 1956 by Vale (then known as Inco) following the adoption of new exploration technology and the largest exploration program to-date in the company’s history.  Mining of the Thompson orebody began in 1961.

“We see the lighting of a path forward to a sustainable and prosperous future for Vale Base Metals in Manitoba,” said Gary Annett, General Manager of Vale’s Manitoba Operations.
