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 anticipated to deliver increased copper recoveries of 87.6% at a 25% concentrate grade. The redesigned plant incorporates an MF2 circuit with Jameson cell ultrafine flotation technology and an optimized reagent scheme, which is expected to reduce processing costs by up to $1.00 per tonne milled. Glencore Technologies is prepared to offer a performance guarantee for the improved recovery estimate, providing strong confidence in the results.
