Los AzulesLos Azules, an advanced-stage porphyryPorphyry copperCopper project in the Andes Mountains of San Juan, ArgentinaArgentina, is focused on evaluating leachable copperCopper potential across multiple different lithologies. A three-phase metallurgical program was conducted using both historical and newly-drilled core samples to assess leachingLeaching performancePerformance through bottle rolls and column leach tests. The testing explored ore from multiple mineralization zones and lithologies to evaluate copper recoveryCopper recovery, acid consumption, and leach kineticsLeach kinetics. Ongoing experiments in Santiago are testing additivesAdditives like wetting agentsWetting agent and sulfurSulfur substitution to enhance copper recoveryCopper recovery while potentially reducingReducing acid consumption. Preliminary results from ongoing tests have informed process designProcess design and identified strategies to optimizeOptimize economics while maintaining environmental responsibility. The findings will ultimately contribute to improving test methodologies for the Los AzulesLos Azules project.
