Electrifying the Future

ELECTRIFYING THE FUTURE Advancing New Leach Technologies Taking Leach to the Next Level • Industry leader with long history of leach production Internal and external initiatives to advance sulfide leaching technologies and to drive continuous recovery improvement • Data analytics providing new insights to drive additional value ⚫ Focused on traditional ores and ores that have been typically considered difficult to leach, like. chalcopyrite Leveraging both R&D and in-field trials at existing leach stockpiles and future opportunities to recover copper from below mill cut-off grade material Success would enable utilization of latent tank house capacity with limited capital investment • Low carbon footprint See Cautionary Statement.
