Vancouver, British Columbia: Calibre Mining Corp. (TSX-V: CXB) (the "Company" or "Calibre") is pleased to report that initial trench data from the Borosi gold-silver-copper project area in northeast Nicaragua has been received from ALS CHEMEX labs of North Vancouver BC. Sampling results from the La Luna and Blag targets within the Eastern Epithermal Camp have confirmed the presence of new low-sulphidation epithermal gold-silver vein trends.
"The trenching program has confirmed the presence of epithermal gold vein systems that were outlined with our initial soil sampling and mapping program." Robert Brown, President and CEO of Calibre stated. "These trench results have further defined our initial targets that will be followed up with a multi-rig drill program beginning in the first quarter of 2010."
The La Luna vein system is at the south end of a 10 kilometres by 12 kilometres epithermal camp of gold bearing veins within the Borosi concessions. La Luna is characterized by a north west trending low sulphidation epithermal quartz vein system that has been traced over a distance of two kilometres. The northern extension of the La Luna vein system has been tested by seven trenches over a strike length of 900 metres. Highlights from the trenching include trench BTR10-009 which intersected 18.2 metres grading 1.00 g/t gold, including 3.49 g/t over 4.2m, and trench BTR10-011 which intersected 3.2 metres grading 3.92 g/t gold and 1.30 metres of 3.36 g/t Au in two separate quartz veins. Assay results from additional trenching at La Luna will be released when they are received.
Highlights of the trenching results are as follows:
In addition, four trenches have been completed on the central portion of the Blag vein system located 9.5 kilometres northeast of La Luna. The four trenches have tested a strike length of 350 metres and the zone is open in both directions along the northeast-southwest strike. Highlights from the trenching include Trench BTR10-013 which intersected 0.80 metres grading 2.10 g/t Au. Trenching continues on the western zone, a 900 metre by 400 metre north-northeast trending vein system at Blag. Further results will be released when received.
In 2010, the Company plans to develop and test drill targets along the La Luna vein trend as well as other high priority veins in the Eastern Epithermal Camp. The exploration program at Calibre's Borosi Gold-Copper-Silver Project is being funded by B2 Gold Corp ("B2 Gold") whereby B2 Gold can earn a 51% interest in the project by funding $8.0 million in exploration expenditures over a 3 year period. The Borosi exploration budget through July 2010 is $2.5 million. Calibre is the project operator.
Quality assurance and quality control procedures include the systematic insertion of blanks, standards and duplicates into the trench sample strings. Samples are placed in sealed bags and shipped directly to ALS CHEMEX labs in North Vancouver BC for gold fire assay and ICP multi element analyses.
