Calibre Mining Corp. announced results from the current phase of exploration activities on the 100% owned, high-grade Montes de Oro Gold Project, and additional gold targets within the Siuna District, Nicaragua. The highlights includes: Three additional trenches were completed in the northern half of the 400 metre by 600 metre gold in soil anomaly on the Montes de Oro Project; Step-out trench MTR14-030 located 300 metres north of trench MTR13-009 (52.3 metres grading 7.07 g/t Au) intersected 8.45 metres grading 3.42 g/t Au and 11.34 g/t Ag, Additional trenching is planned to further extend and define gold mineralization at the Montes de Oro Gold Project; A 25 line kilometre ground magnetic survey was completed in fourth quarter of 2014; An Induced Polarization (IP) Survey consisting of five lines each 1.2 kilometres in length is underway and will be completed in January 2015; and Sampling and Geological Mapping has been commenced on a series of targets which have similar geological and geochemical features to Monte de Oro.

The Montes de Oro target is a 400 metre by 650 metre gold (and multi-element) in soil anomaly which has been successfully tested by trenching with results including 52.3 metres grading 7.1 g/t Au, 27.5 metres grading 4.92 g/t Au and 33.5 metres grading 2.10 g/t Au. Work to date at Montes de Oro has defined two high-grade, sub-parallel gold mineralized zones: one 250 metres long and one 500 metres long. Both zones are open for expansion.

Trench MTR14-030, located 300 metres north of trench MTR13-009 which intersected 52.3 m grading 7.07 g/t Au, exposed silicified and argillic altered diorite with variable quartz veining averaging 8.45 metres grading 3.42 g/t Au and 11.34 g/t Ag. The gold and silver values are associated with elevated levels of zinc, lead, arsenic, iron, and copper. Trench MTR14-031 was completed 250 metres north-east of trench MTR14-030 and intersected low grade halo mineralization including 6.70 metres grading 0.11 g/t Au - an extension to this trench is planned.

Trench MTR14-032 was completed 300 metres north of trench MTR14-031 and sampling returned 2.00 metres grading 2.63 g/t Au.
