VANCOUVER - Calibre Mining Corp. reported that a Phase 1 diamond drilling program has begun on the Minnesota Gold Project within the B2Gold Corp. Joint Venture on the Borosi concessions, northeast Nicaragua. Calibre controls a 49.0% interest in the joint venture and B2Gold has a 51.0% interest and is project operator. B2Gold has the right to earn an additional 19.0% in the Borosi concessions joint venture by spending $6.0 million in additional project expenditures over three years.

The Phase 1 diamond drilling program at the Minnesota gold project will consist of a planned 1500 meters in up to 13 drill holes. The drilling is designed to test several gold zones along the three km strike length of the strong auger and soil gold anomaly. Several drill holes are planned in the vicinity of contiguous Trenches MINTR14-006 to 011 and MINTR14-016 which intersected 109.6 meters grading 1.58 g/t Au.  This trench interval includes the recently received assay results from Trench MINTR14-016 that returned 15.1 m grading 1.2 g/t. Greg Smith, President and CEO said, "With the start of the Minnesota gold project drilling program with B2Gold and with the on-going drilling program with IAMGOLD Corp at the Eastern Borosi gold project Calibre and our partners will be completing a combined 6,500 meters of drilling in up to 58 drill holes on the two gold projects at no cost to Calibre.
