concessions
The 100% Calibre owned Borosi concessions cover over 860 square kilometres in northeastern Nicaragua. The Mining Triangle has been one of the most prolific mining
districts in Central America with a rich history of mining. Calibre has a NI 43-101 compliant inferred resource totaling 1,057,750 ounces of gold and 8,430,070 ounces
of silver on the 100% owned Cerro Aeropuerto, La Luna and Riscos de Oro Prospects and a NI 43-101 compliant inferred resource totaling 118,000 ounces of gold,
2,350,000 ounces of silver and 108,000,000 pounds of copper on the Rosita Prospect which is subject to a joint venture with Alder Resources.
