The Wolf Lake (Waldie Lake) showing is within an east trending fault zone which has been intruded by a quartz-porphyry dyke of the Middle to Late Jurassic Nelson Intrusions. The fault and dyke system also host a late stage quartz vein which carries massive to disseminated pyrite and chalcopyrite. Country rocks are the siliceous sediments and quartzites of the Hadrynian Three Sisters Formation of the Windermere Supergroup (correlative with rocks of the Horsethief Creek Group).

Grab samples of quartz and massive pyrite assayed up to 34 grams per tonne silver and 19 grams per tonne gold although the sampling showed generally lower values and the erratic metal distribution typical of such vein deposits (Assessment Report 12119). The 1 to 3 metre wide dyke has fault gouge developed along both contacts with the country rock.
