May 15, 2020 (Therese Pettigrew) - Much of the southern half of the property is underlain by light to medium grey, fine-grained andesite flows. Light grey to white weathering felsite is abundant in the northern half and basalt crops out in the northeastern portion. The felsite has been interpreted as intrusive (Davies 1978), but may have an extrusive component. Feldspar porphyry dikes occur in many outcrops and the edge of the Canoe Lake quartz diorite stock is exposed near the northern margin of the property. A west-northwest-trending lineament, interpreted to be a fault (Davies 1978), bisects the property and may be related to the numerous mineralized shear zones. A zone of tectonic breccia, which is exposed at the south shaft 50 m south of the lineament, may reflect movement oblique to the fault (Davies and Smith, 1988).

May 15, 2020 (Therese Pettigrew) - At least 10 mineralized zones have been identified. Feldspar porphyry dikes are commonly associated with southeast-trending, north-dipping, carbonatized and pervasively silicified shear zones. Thin quartz veins and veinlets represent later fracture fill. Pyrite is abundant within sheared felsite and is found in minor amounts, together with rare chalcopyrite and molybdenite, within quartz veins. Vein No. 6 is a northeast-trending, north-dipping breccia zone (Davies and Smith, 1988). Anomalous gold values have been reported by Dunlop (1964), who considered high gold values to correspond with high pyrite content. Olympia Mines obtained the following results from their 1964 drill program: DDH 1A returned 0.32 oz/t Au over 1.9 ft (10.97 g/t Au over 0.58 m); DDH 4 returned 0.12 oz/t Au over 7 ft (4.11 g/t Au over 2.13 m); DDH 5 returned 0.33 oz/t Au over 5 feet (11.3 g/t Au over 1.5 m), 0.34 oz/t Au over 1.4 feet (11.66 g/t Au over 0.43 m), and 0.22 oz/t Au over 2.6 ft (7.54 g/t Au over 0.79 m) (Davies and Smith, 1988). Samples from the “Snake Pit” returned values ranging from 0.67 to 3.18 oz/t Au (22.97 to 109 g/t Au). A sample from the “Open Cut” occurrence returned 1.26 oz/t Au (43.19 g/t Au) (Assessment report 52E10SW8552).
