Point Location Description: General
Location Method: Conversion from MDI
Access Description: Located on an island in Caviar (Sturgeon) Lake about 4 miles south of the Virginia Mine.
1899: claim staked and work conducted. Shaft sunk to 100 ft. 1903: work stopped due to low gold values and operating difficulties due to water

Aug 31, 2017 (Therese Pettigrew) - Bands of schistose basic metavolcanics and quartz porphyry cut by NE-striking shear zones (Beard and Garratt, 1976). The island is traversed by alternation bands of greenstone and quartz porphyry, which have a strike curving east by north at the western end to near north east at the northeastern end of the island. The schistosity is not parallel to the strike of the beds. There are shear zones which bear N25E, crossing the original schistosity. The well-sheared porphyry is a sericitic schist, but the shearing appears to have been strong only along certain zones of weakness, leaving intervening plates of massive rock (Burwash, 1933).

Aug 31, 2017 (Therese Pettigrew) - The contact between the quartz porphyry and the shear zone is the most favourable, with an 8 ft wide vein of 50% quartz noted (Beard and Garratt, 1976). The gold values are confined to the part of the shear zones that cutes the quartz porphyry, in which the shaft was sunk to a reported depth of 100 ft. The mine was provided with a crusher and rolls housed with the headframe and connected by a short tram with a 10-stamp mill. A forge, hoist pump, and assay office completed the equipment. Some ore was treated, and it is said that a small amount of gold was produced. Water in the mine caused great difficulty. The vein was reported as 8 feet wide, and rich samples of ore containing native gold were said to be obtained from it. The last work reported on this mine was done in 1903. The following assays were secured by Burwash: (1) Mineralized quartz porphyry somewhat sheared and injected with quartz, which here appears subsequent to the mineralization in cracks penetrating the rock at a different angle, gave $4.20 per ton in gold (approx. 0.12 oz/t Au or 3.7 g/t Au. (2) Quartz stringers, carrying carbonate, penetrating the mineralized schist gave 40 cents per ton in gold (approx. 0.01 oz/t Au or 0.3 g/t Au) (Burwash, 1933).
