Jun 25, 2010 (A Pace) - Surface geology identified by Preliminary geolgoical Map No. P. 302 illustrates that the showing is located within mafic to intermediate volcanices and interflow sediments. Iron Formations have been mapped in the vincity of the showing. Drill holes completed in 1962 have identified intersections of mafic to intermediate volcanincs, greywackes, volcanic tuffs, Diabase, Lamprophyre dyke and quartz porphry. Drill core logs of 1962 have described the rock units to have a schistose fabric

Jun 25, 2010 (A Pace) - Four out of the eleven diamond drill holes conducted by Joubin F.R, MacIintosh, J.A., and Lien, H.O. were drilled in the vicinity of McGovern Lake east. The drill holes had intersected a schistose section that is primarily chloritic in composition. Silicification is evident with pyrite, pyrrhotite and minor chalcopyrite present as the dominant sulphides. Drill hole number 1 had a 3 foot section assayed at 0.02% copper. The drill logs also documented sections of chert with narrow bands of magnetite. Drill hole number 4 intersected a section of chlortie schist with pyrite and pyrrhotite with frequent white quartz bands. A 13.7 foot sample assayed 0.01 oz/ton gold.
