Jan 13, 2020 (Therese Pettigrew) - An east-trending fault zone has brought quartz diorite of the Canoe Lake stock into contact with north-northeast-trending mafic metavolcanic flows and a fine-grained, felsic fragmental unit. Incorporated within the zone are dextrally offset slices of the mafic rocks. These include a thin porphyritic gabbro, with large (up to 25 mm), saussuritized feldspar phenocrysts, a fine-grained basaltic unit, and a medium-grained gabbroic unit. These units probably correspond to similar units on the Sirdar Peninsula to the west. A strong positive magnetic anomaly is coincident with this fault zone (Davies and Smith, 1988).

Jan 13, 2020 (Therese Pettigrew) - Gold mineralization on the property is restricted to thin, weakly to moderately silicified, weakly pyritiferous, east-trending shear zones within quartz diorite, and in a fault slice consisting of fine-grained basalt which is in contact with porphyritic gabbro (Davies and Smith, 1988). Test pits and three shafts were sunk on quartz veins along a fault-controlled contact between quartz-diorite and basalt (Assessment report 52E10SW8557). A sample collected from a 20-cm-wide shear zone between the main and vent shafts returned a value of 0.06 oz/t Au (2.05 g/t Au). The shear zone is in a quartz diorite. Southeast of the vent shaft a shear zone 14 metres wide in the same quartz diorite was trenched and sampled (T1). An assay of .02 oz/T over 9 metres was obtained • and the rock contains some large (1 cm) cubes of pyrite (Assessment report 52E10SW8582).
