News Focused on responsible business and value creation

Vancouver, British Columbia: Calibre Mining Corp. (TSX-V: CXB) (the "Company" or "Calibre") is pleased to announce that it has increased its land position in the historic mining triangle of Nicaragua to over 867 sq kilometres with the addition of the Asa and Pis Pis concessions. The concessions cover a 25 by 10 kilometre area of limestone and calcareous sediments that have been intruded by granitic rocks. The whole area was subsequently overlain by rhyolite and andesite volcanics. The concessions cover the inferred south west extensions of the producing Bonanza low-sulphidation gold-silver camp and the northern extensions of the historic Siuna gold skarn camp.

"The additional concessions gives Calibre a commanding land position in the Historic mining triangle of North East Nicaragua" stated Robert Brown, President & CEO "This underexplored area is highly prospective for both low-sulphidation gold --silver vein systems and gold -- copper skarn and porphyry related deposits. We look forward to testing the potential of these new concessions in the future with a regional stream sediment survey."

A new map, showing the addition of the Asa and Pis Pis concessions is available on the Calibre website (www.calibremining.com).

Calibre Mining Corp. is an aggressive TSX Venture Exchange listed company (TSX.V: CXB) that is focused on the acquisition, exploration and development of gold, silver and copper deposits in Central America. Major shareholders of Calibre include Sun Valley Gold and Yamana Gold Inc.
