The Lucky Strike occurrence is located at an elevation of approximately 1000 metres on a ridge separating the northern headwaters of Eldorado Creek and the South Salmo River, approximately 1.7 kilometres east of the northern end of Rosebud Lake.

Regionally, the area is underlain by fine clastic sediments of the Lower to Middle Ordovician Active Formation, sediments and carbonate rocks of the Middle Cambrian Nelway Formation, undivided sedimentary rocks of the Cambrian Laib Formation and quartz arenite sedimentary rocks of the Neoproterozoic to Lower Cambrian Hamill Group. To the north these have been intruded by granodioritic rocks of the Cretaceous Anstey pluton, and a small stock of syenitic to monzonitic intrusive rocks of the Eocene Coryell Plutonic Suite outcrops to the southeast.

Locally, a fissure vein striking 290 degrees with a steep to near vertical dip is associated with the Black Bluff fault and is host to quartz gangue containing galena, tetrahedrite, pyrite, sphalerite and chalcopyrite. The width of the vein averages 5 centimetres but locally may be as wide as 50 centimetres. The vein crosscuts dolomites and limestones of the Middle Cambrian Nelway Formation as well as phyllites and quartzites of the Lower Cambrian Laib Formation. The country rock also includes several pre-veining–aged diorite dikes. Near surface and to a depth of approximately 5 metres the vein is highly weathered and contains cerussite, chalcocite, covellite, malachite and azurite. There is some cross fracturing and quartz veining on a north trend with steep west dips.

The fissure vein has been explored by an adit and a number of opencuts over a strike length of approximately 150 metres, whereas the strike extension of the vein to the northwest and on the other side of a small swamp has been explored by the Davne (MINFILE 082FSW257) occurrence.

Another area of mineralization is located approximately 150 to 450 metres north of the main workings. This zone, referred to as the East Gold Anomaly, comprises a north-northeast-striking and steeply east-dipping, thinly bedded silty limestone cut by west-northwest fracture zones filled with carbonate and quartz hosting minor tetrahedrite, galena and pyrite mineralization.

The main fissure vein carries silver and gold values but mineralization is highly erratic, ranging from trace up to in the order of 65 grams per tonne gold or better and as high as 13 kilograms silver per tonne from selected grab samples (Minister of Mines Annual Report 1938).

In 1988, a sample (1100) of mineralized phyllite from the main workings assayed 3.92 grams per tonne gold, 182.3 grams per tonne silver and 7.458 per cent zinc, wheras samples of dump material yielded up to 43.60 grams per tonne gold, 216.2 grams per tonne silver and 8.464 per cent zinc (Assessment Report 18364).

In 1992, a diamond drill hole, located approximately 150 metres north-northwest of the Lucky Strike workings and near the north end of a small swamp on the southern end of the East Gold Anomaly zone, failed to intercept the Black Bluff fault zone, but a zone of brecciated quartz-calcite veinlets with minor sulphides yielded values up to 0.73 gram per tonne gold over 5.4 metres of very broken core, including 2.16 grams per tonne gold, 11 grams per tonne silver, 1.520 per cent zinc and 0.170 per cent lead over 3.0 metres (Assessment Report 22921).

In 1994, rock samples from the area of the 1992 drillhole are reported to have yielded up to 11.14 grams per tonne gold and 195 grams per tonne silver from a sample limey siltstone, whereas other rock samples taken approximately 100 metres north of the previous samples yielded up to 8.37 grams per tonne gold and 398 grams per tonne silver and a lone sample taken approximately 100 metres further northeast of the previous samples yielded 3.92 grams tonne gold with 137 grams per tonne silver (Assessment Report 23711).

In 2007, a chip sample of the Lucky Strike vein and adjacent phyllite wallrock from a former trench assayed 30.70 grams per tonne gold, 1260 grams per tonne silver, 2.45 per cent lead, 5.2 per cent zinc and 1.6 per cent copper (Assessment Report 32681).

From six years between and 1938 and 1963 (inclusive), a total of 55 tonnes was mined, from which 2456 grams of gold, 65 191 grams of silver, 2318 kilograms of lead and 1115 kilograms of zinc was recovered. Most of the production was from 1938, when 34 tonnes were mined.

The area was first staked in 1936 by G. Birtsch, with minor production occurring during 1938 through 1940 along with the development a short adit and number of opencuts. In 1961, the claims were re-staked by L. DeKock with minor production occurring through 1963.

In 1981, a ground magnetic and electromagnetic survey was completed on the area as the Tur claims. In 1982 and 1983, further programs of ground geophysical surveys, geochemical sampling and prospecting were completed on the area as the Bine and T Fox claims. In 1988, International Corona Corp. completed a program of geological mapping and rock, silt and soil sampling on the area as the Zip 1-2 and Lone Silver 1-3 claims.

In 1992, Pan Orvana Resources completed a program of geochemical sampling and a single, 160-metre long, diamond drill hole on the area.

During 1994 through 2018, M.A. Kaufman conducted programs of rock and soil sampling, geological mapping, 14.8 line-kilometres of ground electromagnetic and magnetic surveys, a 0.3 line-kilometre gravity survey, minor trenching and two diamond drill holes, totaling 189.0 metres, on the area as the Gus claims.
