Calibre Mining Drilling Continues to Expand Gold-Silver Vein Systems at Eastern Borosi Project, Northeast Nicaragua - Seite 2

Exploration to date on the Eastern Borosi Project has outlined several tens of kilometres of highly prospective mineralized structures located in an historic gold-silver mining district. Targets have been defined by surface soil and rock sampling, trenching and drilling.

To date in 2016, 18 holes have been completed (5 East Dome; 4 Blag Main; 3 Santos Trend; 3 Vancouver vein; 3 Vein Swarm for total meterage to date of: 3,487.53 metres (1,017.00m East Dome; 696.39m Blag Main; 466.64m Santos Trend; 686.24m Vancouver vein; 621.26m Vein Swarm). Results have been received and are being reported in this news release for the first 11 holes including five holes drilled at East Dome, three holes completed at Main Blag and three holes testing the Santos Trend. Additional drill holes completed and being assayed include; three holes testing the Vancouver and Guapinol Vein System, three holes on the Blag Vein Swarm target, and an additional drill hole at the Main Blag Structure.

Drilling in 2016 is targeting a series of high grade gold-silver vein systems defined by the 2014-2015 drilling campaigns. Step out drill holes are testing down plunge and on-strike extensions.

Low sulphidation epithermal gold-silver mineralization intersected on the Eastern Borosi Project is hosted within porphyritic andesite and consists of structurally controlled, high energy quartz-carbonate vein breccias, vein-stockworks and discrete smokey quartz veins containing fine grained sulphide minerals.

Drilling on the East Dome has extended the mineralization 150 metres to the south and 75 metres below previous drilling. The step out drilling on the East Dome has intersected 4.51 metres grading 1.82 g/t gold and 146.3 g/t silver including 1.56 metres grading 4.44 g/t gold and 142.9 g/t silver (BL16-024), 6.00 metres grading 0.23 g/t gold and 103.7 g/t silver (BL16-025), 11.00 metres grading 0.01 g/t gold and 23.6 g/t silver (BL16-026), 0.53 metres grading 0.49 g/t gold and 96.0 g/t silver (BL16-027), and 1.60 metres grading 0.24 g/t gold and 100.4 g/t silver (BL16-028). Additional step out drilling will be completed on the East Dome target.
