Calibre and B2Gold Extend Trench Intercept to 61.9 Metres Grading 1.76 g/t Gold at the Minnesota Gold Project, Borosi Concessions, Nicaragua

VANCOUVER, BRITISH COLUMBIA--(Marketwired - July 8, 2014) - Calibre Mining Corp. (TSX VENTURE:CXB) (the "Company" or "Calibre") is pleased to announce results from follow-up trenching and sampling at the Minnesota Gold Project within the B2Gold Corp. ("B2Gold") (TSX:BTO)(NYSE MKT:BTG) 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 2014 exploration program on the B2Gold joint venture is budgeted at $1.2 million.

The latest results on the Minnesota Gold Project have further extended the previously defined gold mineralization increasing the trench intercept to 61.9 metres grading 1.76 g/t Au. The trenches continue to expose intensely sericitized granodiorite with strong hematite staining and variable silicification. The gold mineralization in the trenches remains open to the north and south.

Trenches MINTR14-008 and MINTR14-009 are additional extensions to the south of Trenches MINTR14-006 and MINTR14-007 which intersected 30.5 m grading 2.01 g/t Au (see Calibre New Release dated June 17, 2014).

Notes;	* previously reported
	Length weighted averages from uncut assays.
	Mineralized intervals are open to the north and south.
	** Combined weighted averages assign zero grade to a 1.0 m gap left unsampled between each of the four trenches

Exploration at Minnesota continues with new trenches planned 100 meters northeast and southwest of Trenches MINTR14- 6 through 9 at high angles to the apparent trend of the gold mineralization.
