For manganese, electrolytic manganese metal (EMM) is the typical intermediate product refined into batterygrade manganese sulfate. We primarily focused on this production path. The predominant copper deposit types are porphyries, sulfides, and stratiform. We modeled all three, and sourced comparables on a variety of deposits.
