The Tiger showing is located on Mt. Wirth, approximately 42 kilometres northeast of Kimberley and 5 kilometres east of Premier Lake.

The Tiger occurrence area is underlain by moderately dipping Middle-Upper Cambrian Jubilee Formation limestone, with underlying conformable strata of the Helikian Purcell Supergroup (Nicol Creek and Sheppard Formations) forming the western limb of the Lussier River syncline. The strata are intruded to the east by a Cretaceous monzonite stock.

At the Tiger workings, tetrahedrite-chalcopyrite replacement-style mineralization occurs in Jubilee Formation limestone. The sulphides are developed along preferred fractures and have sharp contacts with the limestone. Oxidation has produced spectacular textures, which form in the boxworks produced by weathering. Brilliant colours of malachite and azurite form the oxidized mineralization.

The area was first explored in the 1890s, with several adits being driven in the area. Approximately 100 tonnes of ore was shipped from these adits. The area was not worked again until the 1930s, when additional exploration drifting was completed.

The area was abandoned until 1987, when T. Hoy and G. Carter completed regional mapping and the claims were staked by Ed Helgren, who then optioned the claims to South Kootenay Goldfields Inc.

In 1989, South Kootenay Goldfields Inc. completed an exploration program of geological mapping, heavy mineral geochemistry and prospecting. A grab sample from the Tiger workings assayed 5.34 grams per tonne gold, 1232.36 grams per tonne silver and 26.9 per cent copper (Assessment Report 19419).

In 1990, South Kootenay Goldfields Inc. conducted geological mapping, VLF-EM geophysical surveys and geochemical sampling. Highlights of this program include chip sample 57170, which assayed 0.7899 per cent copper and 17.4 grams per tonne silver over 0.15 metres, and float sample 57167, which assayed 3.1 per cent copper, 0.24 per cent lead, 0.91 per cent zinc, 90.87 grams per tonne silver and 2.03 grams per tonne gold (Assessment Report 20754).
