About Calibre
Calibre Mining is exploring a commanding and strategic, 710 sq kilometre land position in a highly prospective, but underexplored region of the historic "Mining Triangle" in northeast Nicaragua. The Borosi Concessions, named for the three historical producing regions of Bonanza, Rosita and Siuna, are highly prospective for gold and copper mineralization associated with skarn and epithermal deposits. A systematic and disciplined exploration program is being conducted at Borosi and three projects within the concessions advanced to the drill testing stage in early 2010.
