Conventional Open Pit Mining

Mining operations use conventional open pit mining methods at the Limón Central open pit and a combination of top-down and bottom-up sequenced longitudinal open stoping ("LOS") at the Santa Pancha underground mines. The El Limón processing plant consists of agitated cyanide leaching and carbon adsorption, followed by carbon elution, electrowinning, and doré production. The annual throughput is approximately 500,000 tonnes per annum ("tpa") and the historical recovery is 94% to 95%.

Calibre’s asset base includes multiple ore sources, 2.7 million tpa of installed mill capacity from two processing facilities (Limon and Libertad), reliable in-country infrastructure, and favourable transportation costs. The Company will continue to optimize its consolidated mine and process plans as the Company progresses our “hub-and-spoke” approach to maximizing value from our integrated asset base.
