Oct. 15, 2019 (GLOBE NEWSWIRE) -- Calibre Mining Corp. (TSX-V: CXB) (the “Company” or “Calibre”) is pleased to announce the closing of the transaction with B2Gold Corp. (“B2Gold”) pursuant to which Calibre has acquired B2Gold’s interest in the El Limon and La Libertad gold mines, the Pavon gold project and additional mineral concessions in Nicaragua for aggregate consideration of US$100 million, which was paid with a combination of cash, common shares, a convertible debenture and a US$10,000,000 cash payment, or at the option of B2Gold, a portion in common shares of Calibre, which will be payable one year from the date of closing (the “Transaction”).
Deposit Type
- Epithermal
- Vein / narrow vein
Summary:
Gold mineralization in the Limón district is associated with quartz-adularia vein systems classified as low sulphidation epithermal deposits. These deposits were formed at relatively shallow depth, typically from just below the surface to a little over one kilometre deep, from reduced, neutral-pH hydrothermal fluids with temperatures of <150o C to 300o C. The volcano-plutonic arc of western Nicaragua is a common tectonic setting for these deposits.
Mining Methods
- Truck & Shovel / Loader
- Longhole stoping
Summary:
Most of Limon’s Mineral Resources and Mineral Reserves are located on the Santa Pancha structure, which is currently mined by long-hole stope underground mining methods. Access to mining areas is by a ramp system that branches at the 90-metre level into north and central ramps. The deepest level of the mine is at approximately 170 metres below surface. Two raises support the mine ventilation system with one of them serving as an emergency escape way. Dewatering is a critical component of mining at Santa Pancha and pumps are currently working in two of the existing shafts to ensure that safe water levels are maintained below the deepest workings. Continued deep development in Santa Pancha and improvements in this dewatering system represent a significant portion of the capital estimate for the next few years.
Processing Technologies
- Agitated tank leaching
- Carbon in pulp (CIP)
- Cyanide (reagent)

Summary:
The Limon Mine mill is a nominal 1,000 tonnes per day agitated leach/CIP gold recovery plant.
