The La Libertad exploitation concession covers an area of 10,937.08 ha and was granted by Ministerial Decree for a 40-year term in 1994. The Project also comprises the Buenaventura and Cerro Quiroz exploration concessions, which are contiguous with the La Libertad exploitation concession and cover a total area of 4,600 ha. The Project is located approximately 110 km east of the capital of Managua and is accessible by road. [Click here for mine/project location map.]

The La Libertad processing plant can treat approximately 2.25 million tonnes per annum (tpa), and current gold recoveries are approximately 94% to 95% for a blend of spent ore and run of mine (ROM) ore. Currently the mine is fed by ore trucked from Limon and Pavon as well ore mined near the mill at the Jabali underground mine. The Jabali underground mine uses a bottom-up sequenced long hole stoping mining method with unconsolidated backfill. The historically mined Jabali Antenna and San Antonio pits are also set to be mined in future.

The Libertad mill currently has surplus capacity and therefore benefits from satellites deposits within a 300km radius.

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.

La Libertad Exploration Opportunity

Calibre has an extensive ongoing exploration program focused on resource expansion and discovery. Currently Calibre has one rigs operating within the Libertad mineral concessions testing new veins systems mapped on surface including Rosario, Tranca, Nancite and the Cosmotillo district. Additionally Calibre has outlined new regional targets at the Amalia and El Nispero concessions and has 1 drill rigs exploring new vein systems at Amalia.

Highlights

• 411 km² district property position: Libertad: 155 km²; Amalia: 84 km²; El Nispero: 172 km²
• Multiple sub-parallel vein systems mapped at surface
• 20,000 metre drill program underway
• Results demonstrating near surface open pit potential
• Amalia and El Nispero located approximately 30 kms from the Libertad mill

Amalia

• Newly discovered; 35 km to Libertad mill
• 12 km trend of under-explored epithermal gold veins
• 84 km² land package with limited exploration and new vein sets discovered during 2020
• Espinoza Vein
