Sinking the Lucky Strike shaft began in 1897. It is flooded (ca. 1956) and located 823 metres south of the Iron Mask shaft (092INE010). At a depth of 18 metres a drift of unknown direction is reported to extend 36.5 metres on a vein said to be 0.9 to 1.2 metres wide. Recorded production is 27 tonnes in 1901, containing about 20 per cent copper with minor gold and silver values. The shaft was retimbered in 1951. A small dump shows disseminated chalcopyrite in diorite. The sulphide is not intimately related to pink feldspar veins, but occurs close to calcite-filled fractures. Magnetite veinlets also occur. The diorite is part of the Cherry Creek unit of the Late Triassic-Early Jurassic Iron Mask batholith.

Three inclined holes were diamond drilled in the vicinity by Berens River Mines Limited through short, induced polarization conductive zones trending east-northeast, and all intersected faults in diorite with only minor mineralization (Minister of Mines Annual Report 1956). See Iron Mask (092INE010) for a detailed work history and geology of the area.

In 1965, a ground magnetometer survey (62.7 kilometres) was conducted on a group of Iron Mask claims on behalf of Kamloops Copper Consolidated Limited.
