Mountain Boy Minerals announces that Great Bear Resources Ltd. has released the first drill results from the BA project in the Eskay Creek mining district near Stewart, northern British Columbia. Diamond drill hole BA-2010-79 intersected three separate mineralized zones at the Main Zone, two of which were previously untested, and one of which carries anomalous gold values.
BA-2010-79 was drilled on a 150 degree azimuth with a -80 degree dip, in order to better characterize the thickness of the main mineralized horizon, and test new host rocks in the footwall of the zone. It intersected 44.04 metres of high grade silver-lead-zinc mineralization in the known zone, termed "Zone 1", but went on to intersect two additional structurally hosted mineralized zones in previously untested volcaniclastic rocks, termed "Zone 2" and "Zone 3".
Previously known mineralization at BA is hosted by sedimentary exhalative sulfide-bearing ("sedex") mudstones intruded by andesite and dacite stocks. Mudstones are sulfide enriched in quartz-carbonate altered zones beside the stocks. New 2010 drilling has shown that high grade mineralization also occurs within silicified, chalcopyrite-bearing high-angle structures, as in "Zone 2".
In addition to high grade silver, lead and zinc, Zone 2 returned gold values of 0.254 g/t over 1.28 metres, demonstrating that high grade mineralization can be gold-bearing at BA. A third zone of structurally hosted silver-lead-zinc mineralization was also encountered deeper in BA-2010-79. This combination of new prospective host rocks, mineralized high-angle structures and associated gold adds a new target type at BA, expanding the scope of this project.
To date, ongoing drilling has completed a total of 31 drill holes at the BA project. Results from this drilling are pending. Ongoing fieldwork has identified stacked sulfide-bearing sedex horizons and stockwork veining that form part of a VMS mineralizing system which is exposed over a mapped length of approximately 1.5 kilometres.
As previously announced, Great Bear has entered into an Option and Joint Venture Agreement with Mountain Boy Minerals Ltd. to earn a 50% interest in the BA project by spending $5.5 M over four years, and can earn an additional 20% interest, for a total of 70%, by completing a Bankable Feasibility Study on or before December 31, 2015.
The BA Project hosts a silver rich volcanogenic massive sulphide (VMS) system that has been drill confirmed for 600 metres of mineralized strike and down dip for 300 metres. The discovery is open for expansion in all directions. 62 of 90 historic drill holes into the Main Zone at BA have returned in excess of 2 oz silver over drill indicated widths of 3 to 134 metres with significant associated lead - zinc mineralization.
