1 Mineral resource estimates that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not include factors for mining recovery or dilution.
2 Mineral resource estimates constrained to a Lerch Grossman pit shell with a revenue factor of 1.0 using a copper price of $3.45 per pound.
3 Using a 0.1% copper cut-off grade and an oxidation ratio lower than 50% for flotation material, and a 0.1% soluble copper cut-off grade and an oxidation ratio higher than 50% for leach material.
