The Chapada mine is located in Goias state, Brazil and is a copper‐gold mine that began production in 2007. Copper production for 2018 was 129 million pounds of copper at cash costs of $1.74 per pound of copper on a co‐product basis. Guidance for 2019 is 120 million pounds expected to be produced.
Significant mine life and throughput expansion potential exists at Chapada through resource conversion to reserves as well as ongoing exploration success. The operator, Yamana is undergoing a phased development plan for Chapada. Phase 1 of this expansion plan is targeting plant optimization for further recovery increases in the range of 2% with commissioning targeted for mid-2019. The feasibility study on Phase 2, which involves a plant expansion to achieve a throughput capacity of up to 32 million tonnes per annum (a 39% increase), is also progressing. Phase 3, which contemplates a pit wall pushback to access higher grade Sucupira ore, advanced with infill drilling completed in June with the results expected to support the ongoing feasibility study.
