Inferred Mineral Resources
The El Limόn mining exploitation permit covers an area of 12,000 ha and was granted by Ministerial Decree for a 25-year term in 2002. The project also comprises the Bonete-Limόn, Guanacastal III, San Antonio, and Guanacastal II exploration permits, which are contiguous with the exploitation permit and cover a total area of 8,147 ha, and Villanueva 2 exploration permit, which is located 12 km north of the exploitation permit and covers an area of 1,200 ha.
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 (El Limon and La 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.
EL Limon Resource Expansion and Discovery Opportunity
Calibre has an extensive ongoing exploration program focused on resource expansion, infill and discovery. Currently Calibre has three rigs operating within the Limon mineral concessions testing on strike extensions to the Veta Nueva underground mine, the recently discovered Atravesada deposit and along strike and down plundge of the Panteon and Santa Pancha underground mines. Panteon was an exciting discovery made during 2020 and as of Q2, 2021 the company has advanced development and will now begin ore mining from Panteon. Additionally, Calibre has one drill testing the strike and plunge potential at the Limon high-grade open pit. To date, Limon open pits have been traced over 2.5 kilometres long and host an open pit reserve of 3.4 million tonnes grading 4.24g/t gold containing 462,000 ounces of gold. Calibre is currently drilling along the Tigra / Chapparal zone which hosts a shallow high-grade resource with potential to expand.
