The Wilcum occurrence is located on the north side of the St. Mary River, approximately 2.5 kilometres northeast of the eastern end of St. Mary Lake.
The area is underlain by argillites and quartzites of the middle Proterozoic Aldridge Formation (Purcell Supergroup). These have been intruded by gabbro sills and dikes of the middle Proterozoic Moyie Intrusions.
Locally, as exposed by trenching, an andesite hosts massive sulphide mineralization including chalcopyrite, pyrrhotite and pyrite. In 2011, a sample (A) from the site 7 trench assayed greater than 1 per cent copper, 2.7 grams per tonne silver and 0.52 gram per tonne gold (Assessment Report 33462).
In 2011 and 2012, the area was prospected and sampled by DW Exploration as the Wilcum property.
