The Garnet No.1 occurrence is located at an elevation of approximately 1200 metres on a south-facing slope, west of Argyle Creek and north of St. Mary Lake.

The area is underlain by argillites and quartzites of the Mesoproterozoic Aldridge Formation (Purcell Supergroup). These have been intruded by gabbro sills and dikes of the Middle Proterozoic Moyie Intrusions.

Locally, quartzites in contact with a diorite sill that strikes 320 degrees and dips 90 degrees host massive sulphides (chalcopyrite and pyrrhotite) associated with garnet, feldspar and hornblende over approximately 120 metres. A pegmatitic intrusive is reported a short distance to the north-northwest of the occurrence.

In 1987, a rock sample (KDR-87-011) assayed 0.115 per cent copper (Assessment Report 16971).

In 1995, a sample (Garnet 19) assayed 0.103 per cent cobalt, 0.14 gram per tonne gold and 1.8 grams per tonne palladium, whereas another sample (Garnet 12) yielded 0.899 per cent copper and 5.4 grams per tonne silver and sample Garnet 22 yielded 0.97 gram per tonne gold (Assessment Report 24295).

Silver mineralization is also reported to the east on the former Hidden Treasure (L.1745), Minnie Ha Ha (L.1744), Matterhorn (L.1743) and Columbia (L.1746) Crown grants.

Work History

Historical workings in the area include at least three adits of unknown length and age that are likely to date back to the late 1890s or early 1900s.

In 1971, Kerr Addison Mines Ltd. conducted a regional program of geological mapping and geochemical (soil and silt) sampling on the are as part of the Dewar Creek project.

In 1983, Trans-Arctic Explorations completed a ground electromagnetic survey on the area immediately south as the P.C. 1 claim. Also at this time, Noranda Mining and Exploration Inc. conducted an airborne magnetic and electromagnetic survey on the area as part of the Mount Evans property. The following year, a program of geological mapping was completed. In 1985 and 1986, Amstar American completed programs of geological mapping, soil and rock sampling and ground and airborne geophysical surveys on the area as the Bootleg and High Peak claims. In 1987, Esso Resources completed a program of rock and silt sampling, geological mapping and a 3.0 line-kilometre electromagnetic survey on the area as the Mac 1-10 claims.

In 1995, the area was prospected as the Garnet No.1 claim. In 1998, Abitibi Mining Corp. conducted a gravity survey on the area. The following year, Abitibi Mining Corp. prospected the area immediately was as the PMR 8-14 claims.

In 2011, the area was prospected and sampled by DW Exploration as the Wilcum property.
