The Bogg property is located 50 kilometres east of 100 Mile House, and 35 kilometres northwest of Little Fort.

The occurrence comprises porphyry-style copper mineralization within and along the northeast margin of the largest syenite stock within the Triassic to Jurassic Friendly Lake Intrusive Complex. Disseminated and fracture-controlled pyrite, chalcopyrite and bornite occur within both the syenitic rocks and adjacent greenstone, microdiorite and intrusion breccia. Edwards (Assessment Report 21776) reports that pyroxene-potassium feldspar-calcite veinlets, interpreted to have formed in the late stages of intrusion of the syenite body, locally contain chalcopyrite and galena.

Disseminated and fracture-controlled pyrite-chalcopyrite mineralization also occurs farther west, within a steeply dipping, northwest striking quartz- carbonate altered fault zone that cuts through the southwestern part of the syenite stock. This zone is up to 300 metres wide and comprises silicified fragments of syenite, microdiorite, greenstone, and altered sedimentary rocks cut by several episodes of quartz and carbonate veins.

A sample collected by the B.C. Geological Survey (Fieldwork 2000) from a pyrite-chalcopyrite-bornite rich intrusion(?) breccia in the main mineralized area of the Bogg occurrence yielded values of 3.3 per cent copper, 25 grams per tonne silver, 0.208 gram per tonne platinum and 0.149 gram per tonne palladium. Another sample, collected by G. Ray in 2002, assayed 2.64 per cent copper, 0.136 gram per tonne gold, 0.56 gram per tonne platinum and greater than 200 grams per tonne silver (Assessment Report 27789).

In 2012, a grab sample (FLJ-01) assayed 2.8 grams per tonne gold, 0.412 gram per tonne palladium, 0.286 gram per tonne platinum and greater than 1.0 per cent copper and 100 grams per tonne silver (Assessment Report 33772).

Exploration work in the area began with a regional geochemical survey conducted by Anaconda American Brass in 1965. They followed up with geochemical and geophysical work, and trenching and percussion drilling until 1970. Gerry Rayner staked the area in 1971. Prism Resources mapped the property in 1972. Cities Services optioned the property from 1973 to 1975 and conducted geophysical and geochemical work, geological mapping, trenching, and diamond and percussion drilling. Further geochemical work and VLF-EM was done by Commonwealth Minerals in 1978. Stan Zastavnikovich initiated exploration for gold mineralization by a regional stream sediment survey in 1986. Geotech Capital Corporation optioned the property and conducted a geochemical survey, induced polarization, diamond drilling and road improvement, from 1987 to 1989. In 1990, Placer Dome Incorporated completed detailed mapping, soil geochemistry and geophysical work on the grid established by Geotech. In 1991, old trenches were resampled and tested for gold. The Bogg occurrence was held as part of the Friendly Lake property of Electrum Resources in 2003 and subsequently optioned to Lithic Resouces Ltd. who worked on the large property in 2004. The property was returned to Electrum in January 2005. Exploration programs completed at the time included geological mapping, geochemical sampling and an airborne magnetic survey. In 2007 through 2012, Electrum Resource, completed programs of rock and soil sampling and a ground magnetic survey on the area as apart of the Friendly Lake property.
