Calibre Mining Corp (OTCMKTS: CXBMF) is a Canadian-based gold and silver producer with a portfolio of operating mines, development assets and exploration projects in Central America. Headquartered in Vancouver, the company focuses on sustainable precious metals production, resource optimization and disciplined project execution across multiple jurisdictions.
The company’s principal producing assets are the Limon and Libertad gold mines in Nicaragua. Both operations employ conventional open-pit mining techniques, with ore processed through a combination of carbon-in-pulp (CIP) and heap-leach facilities to produce gold and silver doré. Since commissioning in 2018, Calibre Mining has implemented a series of operational enhancement initiatives designed to improve efficiencies and extend the life of mine.
Beyond its producing mines, Calibre maintains an active pipeline of exploration and development projects in Nicaragua and Guatemala. Key targets include near-mine and greenfield sites such as Pavon and El Tambor, where systematic drilling programs seek to expand mineral resources and support future production growth. The company holds exploration licenses covering more than 130,000 hectares, positioning it to advance multiple projects toward development.
Established in April 2020 as a spin-out of B2Gold’s Central American portfolio, Calibre Mining draws on a leadership team with deep expertise in mine development and resource management. President and CEO Shawn Wallace leads the organization from its Vancouver headquarters, supported by regional operational teams based in Managua, Nicaragua, to oversee on-the-ground execution and stakeholder engagement.
