Commercial copper production was declared on March 1, 2009, when copper concentrate inventory levels surpassed the 5,000 tonne shipping threshold. Increased zinc levels in the ore body, as it was continuously being mined, prompted the construction of a Cu/Zn separation circuit as extension of the previous flotation circuit.
