The Lucky Jim No. 4 showing is located 6.9 kilometres north-northwest of the confluence of American Creek and the Bear River, about 1400 metres west of American Creek, 24 kilometres north of Stewart.
The area is underlain by north trending, west dipping Hazelton Group rocks on the west limb of the north trending American Creek anticline (Bulletin 58; 63). Red to green volcaniclastics, comprising predominantly volcanic sandstone, siltstone and argillite of the Lower Jurassic Betty Creek Formation overlie red to green andesites and intercalated tuffs of the Lower Jurassic Unuk River Formation (Assessment Report 21405).
The showing, located on the west-central portion of the Lucky Jim No. 4 claim (Lot 5721), comprises mineralized quartz stringers in a shear zone in the Betty Creek rocks. The quartz contains semimassive galena, pyrite and minor chalcopyrite. A grab sample collected in 1990 from the showing assayed 13.4 per cent zinc, 3.3 per cent lead, 0.3 gram per tonne gold and 16.3 grams per tonne silver; copper was slightly anomalous (Assessment Report 21405). In 1994, a 1.3 metre chip sample (KK-950) from silicified crystal tuff hosting up to 10 centimetre wide vuggy quartz stringers assayed 0.61 per cent lead and 0.49 per cent zinc; this zone disappears in a boulder field (Assessment Report 23964).
About 400 metres southwest of the Lucky Jim No. 4 claim on the Lucky Jim No. 6 claim (Lot 5723), a grab sample (KK-935) from a 1 metre wide zone of brecciated red and purple volcanics with lenses of quartz carrying massive galena and sphalerite assayed 1.14 grams per tonne gold, 19.8 grams per tonne silver, 8.25 per cent lead and 11.96 per cent zinc. The quartz stringers strike 142 degrees, dipping 45 degrees and are from 0.2 to 0.3 metre wide (Assessment Report 23964).
Approximately 200 metres southeast of the showing on the Lucky Jim No. 4 claim, on the Lucky Jim No. 3 claim (Lot 5720), is the north end of a south-southeast trending mineralized zone that can be traced for about 1000 metres to the south (Assessment Report 21405). The zone comprises a 4 metre wide silicified replacement zone that hosts a series of narrow quartz veins. The zone is mineralized with chalcopyrite, bornite and minor galena. It was not examined or sampled in 1990.
Three other veins, carrying pyrite and galena, are reported to be on the Lucky Jim claims, but their locations are unknown.
The Lucky Jim claim group was located before 1929. That year, the owners, Bosence and partners, reported several mineralized occurrences on the claims. Montreal-based interests carried out work, including trenching(?), the following year; five veins were reported at this time but their locations are not specified (Property File - Mathews, 1942). Pride Resources Ltd. owned the claims in 1980; no work was reported on the showing. White purchased the claims in 1990. Teuton Resources Corp. subsequently agreed to purchase the claims and carried out geological mapping and sampling on the claims in 1990. In 1994, work on behalf of Minvita Enterprises Ltd. on the Lucky Jim claims was part of a larger program covering several Stewart area properties; a total of 19 reconnaissance rock samples were taken and sent for analyses.
