Mineralization Comments

Apr 29, 2020 (Therese Pettigrew) - Stripping and blast-holes near the southwest corner of the property have exposed a northeastward-striking granodiorite dike, 50 feet in width, containing an albitized cross-fracture system. The company reports that a grab sample, assaying 0.76 ounces per ton in gold was obtained from the showing and that lower values, usually below 0.10 ounces per ton, were obtaining in drilling. A short distance to the south of the dike, a pillow lava flow was observed striking N70W. and dipping steeply to the north. It is intersected by a series of 2-inch quartz-filled cross-fractures, which strike in a north-south direction and dip 70E. The fractures were spaced from 3 to 4 feet apart. Low values in gold were reported to have been obtained from the stringers (Chisholm, 1951). Ginguro’s Area A, located at NAD83 UTM Zone 15, 579400 mE 5538480 mN, returned assays up to 4.63 g/t Au from a quartz-porphyry dyke in sheared metavolcanics with massive iron carbonate alteration. There is quartz veining and some pyrite in the shear and quartz veining in the porphyry dyke One set of 5 samples across the shear / dyke / quartz veins averaged 1.55 g/t Au across 4.0 m (Assessment report 20000002031).
