On October 15, 2019, Calibre completed the acquisition from B2Gold Corp. (“B2Gold”) of the producing El Limόn and La Libertad gold mines as well as the Pavon gold project and other mineral concessions in Nicaragua held by B2Gold for an aggregate consideration of $100 million, to be paid with a combination of cash, common shares and a convertible debenture. Following completion of the transaction, B2Gold will own an approximate 30% direct equity interest in Calibre [click here for the October 15, 2019 news release].
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 Mine is an open pit and underground operation using conventional open pit methods at the Jabali Antena pits and a bottom-up sequenced long hole stoping mining method with unconsolidated backfill in the Jabalí underground mine. 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.
The current La Libertad operation includes the mining of surface and underground Mineral Resources and processing of historically placed heap leach material as well as Mineral Resources produced by surface and underground mining operations.
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. This philosophy was demonstrated during Q1, 2020 at Libertad which delivered 21,449 ounces, despite the ongoing suspension at the Jabali underground mine, with approximately 20% of Libertad’s production sourced from Limon and Pavon

La Libertad Exploration Opportunity
Calibre’s exploration strategy for the Project starting in October 2019 will be to infill drill Inferred Mineral Resources, concurrently with exploration programs that target Mineral Resource expansions at existing and new deposits.
Geology and Mineralization
La Libertad gold district covers an area of approximately 150 km2 and lies within a broad belt of Tertiary volcanic rocks that have been differentiated into two major units called the Matagalpa and the Coyol Groups. The Oligocene to Miocene age Matagalpa Group consists of intermediate to felsic pyroclastic rocks. Unconformably overlying the Matagalpa Group are Miocene-aged mafic to intermediate lavas of the Lower Coyol unit.
The rocks of the Lower Coyol unit host the gold-bearing low-sulphidation epithermal quartz veins in the La Libertad gold district. Gold mineralization at La Libertad is contained within vein sets along two parallel trends separated by approximately 500 m. The Mojón-Crimea Trend is nearly four kilometres long, strikes 065°, and dips on average 80° to the southeast. The down-dip dimension is commonly in the order of 200 m to 250 m. The massive quartz veins and adjacent stockwork/stringer zones range in width from 2.0 m to 70 m for an average of 15 m, often narrowing at depth. The Santa Mariá-Esmeralda Trend is discontinuous, with the Santa Mariá and Esmeralda veins separated by approximately 1,000 m. The Santa Mariá vein averages 10 m wide and is approximately 450 m long. The Esmeralda Vein has been mined out. Additional mineralization is contained within previously mined material that has been crushed and partly processed by heap leach methods.
Exploration at La Libertad mostly comprises drilling. Other exploration methods include prospecting, geological mapping, geophysical and geochemical surveys, and trenching.
Calibre believes there is potential to outline additional resources along the La Libertad Proper concessions, Amalia concessions and Rosario Concession.
Calibre has a multi-prong approach to all exploration activities. Currently the Company is advancing a 60,000 metre exploration, resource expansion and discovery drill program with multiple drill rigs operating on the Libertad Concessions.
Field crews have been mobilized and are mapping, sampling and advancing generative exploration work.
