Highland Copper Announces Updated Process Plant Flow Sheet Demonstrating Increased Copper Recoveries of 87.6% and Reduced Processing Costs
Highland Copper announced positive results from its 2025 metallurgical test work program for the Copperwood Project, demonstrating an updated process plant flowsheet that is expected to increase copper recoveries to 87.6% and reduce processing costs by up to $1.00 per tonne milled. The redesigned flowsheet incorporates ultrafine flotation technology and an optimized reagent scheme, with Glencore Technologies prepared to offer a performance guarantee for the improved recovery estimate. These results are an important component of Phase 1 detailed engineering, aiming to enhance project economics and reduce technical risk.
