Additional Drilling Results From Eastern Borosi Gold-Silver Project

VANCOUVER, BC - Calibre Mining Corp. reported final assay results for the 2014 Phase I drilling program on the Eastern Borosi gold-silver project which is being financed under an option agreement with IAMGOLD Corporation.

During 2014, Partners IAMGOLD and Calibre Mining completed 40 drill holes for a total of 5,505.98 meters, which tested 5 gold-silver vein systems over a combined strike length of 3.0 km. The 2015 Phase II Drilling program has been approved by partner IAMGOLD and will consist of a minimum 5500 meters of drilling with a budget of $1.5 million. Drilling is expected to begin in Q1/2015 and will continue to test down plunge extensions to mineralized shoots found in 2014 and include continued testing for new shoots along previously undrilled veins within a portion of the potential tens of kilometers of vein structures on the Project.

New high-grade results from Guapinol gold-silver vein system include 5.07 meters grading 13.44 g/t Au and 14.49 g/t Ag, 2.76 meters grading 26.48 g/t Au and 24.19 g/t Ag and 1.9 meters grading 14.49 g/t Au and 8.88 g/t Ag. Step-out drilling at the Riscos de Oro Extension located 500 meters along trend from the Riscos de Oro gold-silver deposit intersected 1.6 meters grading 4.42g/t Au and 402.3 g/t Ag and 1.04 meters grading 2.35 g/t Au and 77.2 g/t Ag.

Drilling has been successful in extending the high grade gold/silver mineralization in both the Guapinol and Vancouver gold-silver vein systems a further 50 meters down dip to a vertical depth of 200 meters and confirms the continuity of the previously defined high grade portions of these vein systems.  The Guapinol and Vancouver gold-silver vein systems have been traced by drilling along trend for 620 meters and 420 meters respectively and both systems are open to depth and along strike.

President and CEO, Greg Smith said, "The 2014 Phase I drilling on the Eastern Borosi project was completed on time and under budget. The drilling successfully intercepted high-grade gold and/or silver mineralization in the Guapinol, Vancouver, California, Blag and Riscos de Oro extension vein systems.  Additional drilling in 2015 will follow up on the very positive 2014 results and will continue to expand the tested portions of several structures both along strike and at depth."
