Mineralization Comments

Feb 28, 2008 (A Wilson) - The main vein contains pyrite and chalcopyrite in fractures in the quartz. The sulphides are most abundant along the walls of the vein. Native gold was observed within the mineralized vein. A grab sample collected by the ODM in 1924 returned $94.20 gold (4.71 oz/t gold). A sample collected by Hollinger Gold Mines Ltd. assayed 0.88 oz/t Au. Sampling from the 125-ft level, south drift returned assays ranging from 0.14 oz to 0.58 oz within the quartz vein. Assays from pulps of grab samples from the trenches taken in 1983 returned up to 7.58% Cu. Grab samples collected in 1998 from trenches to the south of the shaft returned assays up to 77.35 g/t gold.
