Cerro Maricunga Reserves and Resources
Reserves
The Cerro Maricunga proven and probable mineral reserve estimate, summarized below, lies within an optimized open pit shell generated using economic and technical input parameters established in the October 2014 Prefeasibility Study. The mineral reserve represents a diluted ore tonnage. No inferred category mineral resources were used in the preparation of the mineral reserves.
The Cerro Maricunga mineral resource estimate and reserve calculation were prepared under guidelines established by the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM"), CIM Standards on Mineral Resources and Reserves - Definitions and Guidelines (2014).
Mineral Resources
The table below summarizes the global mineral resource estimate for Cerro Maricunga unconfined by any pit model. The Mineral Resources are inclusive of the Mineral Reserves.
