Calibre Mining Corp.
Calibre Mining is exploring a commanding and strategic, 785 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 on the Borosi Concessions.
