Western Mines Partners with Magnium to Monetize Waste Rock at Mulga Tank Nickel Project in WA

Western Mines Group has signed a non-binding agreement with Magnium Australia to explore the supply of magnesite from the Mulga Tank nickel project in Western Australia. This move aims to monetize an estimated 348 million tonnes of waste rock, which could provide essential feedstock for Magnium's low-carbon magnesium production. The project, which contains nearly 2 billion tonnes of nickel resources, could significantly improve Western Mines' economic outlook if the agreement leads to a formal supply deal.
