Mineralization Comments

Nov 12, 2014 (A Wilson) - Samples from the trenches reportedly returned assays up to 0.85 oz/t Au, but the average of the gold content of the vein is low.


Nov 15, 2022 (Therese Pettigrew) - The sheared contact between Early Precambrian metabasalt and quartz porphyry contains a quartz vein from 1 to 17 inches wide which was traced 400 feet along a strike of N95E. The veins contains sphalerite, galena, chalcopyrite, arsenopyrite, ankerite, tourmaline, and reportedly gold (SMDR 00537).
