The Cow showing is located about midway between Haimila and Jim Bradshaw glaciers, about 5 kilometres south of the Bowser River.
The area is underlain by green, red, purple and black volcanic breccia, conglomerate, sandstone and siltstone of the Lower Jurassic Unuk River Formation (Hazelton Group) (Bulletin 63).
Mineralization comprises a strongly limonitic, northwest-trending shear which has been traced for about 100 metres. The shear strikes 317 degrees and dips 73 degrees southwest. It varies up to 1.3 metres in width and contains 10 to 15 per cent, 3 to 5 centimetre wide, quartz stringers. The quartz is vuggy and contains traces of sphalerite. Wallrocks comprise variably silicified tuff and lithic tuff. In places the shear is intensely hematized and contains manganese stain (wad?); boxworks are locally developed.
Chip samples assayed anomalous values across widths of 0.4 to 1.3 metres. The best sample assayed 294.5 grams per tonne silver, 0.33 per cent lead. 0.15 per cent zinc, 0.05 per cent arsenic and trace copper across 1.3 metres (Assessment Report 20173).
In 1987, about 300 metres east-southeast of the showing, several anomalous rock chips were identified over an area of 100 by 200 metres. A strongly oxidized and moderately silicified andesitic tuff assayed 17.9 grams per tonne silver, 0.08 per cent lead, 0.41 per cent zinc and traces of arsenic and copper across a width of 1.2 metres (Assessment Report 20173).
In 1987, Teuton Resources Corp. staked the Cow claims and conducted stream sediment and rock geochemical surveys in 1987 and 1989. The mineralization was discovered in 1989. In 1990, Teuton performed a heli-borne VLF-EM and magnetometer survey over the area. The results were disappointing. The following year the company carried out a rock geochemical program northeast of the showing, on the Cow 1 and 2 claims; results were negligible. No work was done on the showing. In 1991, a brief follow-up program of prospecting and rock geochemical sampling was completed on behalf of Teuton Resources Corp.; a total of 70 rock samples were collected for geochemical analysis.
