(TSX-V:KBG) are pleased to announce that they have received more results from their Phase 1 diamond drilling program on their Bobjo Mine Project, located in Earngey Township, Red Lake, Ontario.
The partners are pleased to report that Hole #14 has intersected a new gold zone returning 1.56 opt gold over 8 feet (53.61g/t Au over 2.45 metres). Specks of visible gold were observed in this intersection. The partners are also waiting for the results from a 40 ft heavily mineralized quartz carbonate zone that was intersected deeper in this hole. The mineralization is mainly comprised of pyrite, pyritite and some chalcopyrite. It has been sent to SGS Canada Inc.'s laboratory to be analyzed for gold and 32 elements using the ICP method.
