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 Cu from
below mill cut-off grade material
>>> Success would enable utilization of latent tank
house capacity with limited capital investment
>>> Low carbon footprint
