Calibre Provides Update on Gold Projects in Northeast Nicaragua

Calibre Mining Corp. is pleased to provide an update on the Company's 100% owned gold-silver projects and gold-copper projects under joint venture with B2Gold Corp. and Alder Resources Ltd.

Calibre's Borosi Concessions are located in the historic Mining Triangle (the "District") of northeast Nicaragua that has past production exceeding 8 million ozs of gold. Calibre and our Joint Venture partners control 785 km² of concessions in this prolific mining district which remains largely underexplored for porphyry gold-copper deposits, epithermal gold-silver systems and gold-copper skarn mineralization.
