VANCOUVER, BRITISH COLUMBIA, Dec 09, 2010 (MARKETWIRE via COMTEX News Network) --

Calibre Mining Corp. (TSX VENTURE: CXB) (the "Company" or "Calibre") is pleased to announce encouraging gold exploration results from the 100% owned Bonanza H1 Concession in Nicaragua. A combination of mapping, prospecting, soil sampling and trenching over a 2.5 km x 2.0 km area has delineated several sets of gold-bearing quartz veins extending northeast for 2.5 kilometres from the southern concession boundary. Highlights of the trenching work include 4.7 metres grading 7.30 gram per tonne ("g/t") gold in Trench BTR10-18 and 10.9 metres grading 1.35 g/t gold in Trench BTR10-29. Results from these trenches confirm that mineralization extends at least 600 metres on strike of what is inferred to be the northeast extension of the Washington vein, part of the Panama group of low sulphidation gold veins, currently being mined by Hemco Nicaragua SA ("Hemco").
