The Lodge showing area is underlain by Guichon variety quartz diorite of the Late Triassic-Middle Jurassic Guichon Creek batholith which has been cut by dikes and irregular bodies of younger quartz diorite. Low grade copper mineralization has been found at several places on the property in or closely associated with north-south faults. In 1974, Bethlehem Copper Corporation drilled 2 percussion holes which intersected granodiorite of the Guichon Creek batholith. Mineralization is rare and consists of occasional specks of pyrite, chalcopyrite and molybdenite.

In 1956, a soil geochemical and ground magnetometer (42 kilometres) survey was performed on some of the Lodge claims on behalf of Northlodge Copper Mines Limited. In 1957, the Lodge group of claims was optioned by American Smelting and Refining Company Ltd. which drilled 10 rotary-drill holes totalling 438 metres and constructed 2.4 kilometres of road. Three short rotary test holes were drilled in 1958 by American Smelting and work by Northlodge consisted of geochemical and geophysical prospecting. In 1960, 11 kilometres of induced polarization was run on the Lodge and KB claims groups on behalf of Northlodge Copper Mines Ltd. and Beaver Lodge Mines Ltd. In 1960, the Lodge group of claims was optioned for a time by Rio Tinto Canadian Exploration Limited which did geophysical and geochemical surveying and drilled one hole 172 metres in length. In 1963, an induced polarization survey (13 kilometres), geological mapping and bulldozer trenching was carried out over the Lodge, SD and Dave claims on behalf of Huestis Mining Corporation Limited. In 1973, Valley Copper Mines Limited conducted 29 kilometres of induced polarization survey on the Outrider, Lodge, SD, KB and Bay claims. In 1974, on behalf of Valley Copper Mines Limited, Bethlehem Copper Corporation put down two percussion-drill holes totalling 213 metres on the SD 5 and Lodge 13 claims and Cominco Ltd. completed 3.6 kilometres of induced polarization survey on the SD 5,6 and Lodge 13,14 claims.
