The WB 1 occurrence is located at an elevation of approximately 1860 metres on a west-facing slope, approximately 800 metres northeast of White Boar Lake and 2.6 kilometres north-northeast of Mount McKay.

Regionally, the area is underlain by siltstones, greywackes, quartzites and phyllites of the Proterozoic Upper and Middle Aldridge and Lower Creston formations (Purcell Supergroup), intruded by a small quartz monzonite stock, possibly Cretaceous. The Lower Creston Formation consists mainly of laminated to thickly bedded argillites and siltites with minor fine-grained quartz wackes. The rocks are waxy green to olive in colour with tan-weathering surfaces, wavy bedding and abundant mudcracks. Rocks of the Upper Aldridge consist of a relatively homogeneous unit with occasional thin interbeds of rusty weathering light grey quartzite and laminated light and dark grey argillaceous quartzite. Locally, these rocks are intruded by gabbro or diorite sills and dikes of the Moyie Intrusions. The intrusive stock consists of medium- to fine-grained massive biotite monzogranite. The sediments adjacent to the intrusion have been altered to produce concentric zones of biotite hornfels and siliceous siltstone.

Locally, a crystalline quartz vein in a carbonate-altered quartzite hosts galena-chalcopyrite mineralization associated with limonite, pyrite and chlorite. To the north of the vein a phyllic-altered quartzite hosts trace sphalerite over an area of approximately 20 metres.

In 2007, a sample (W-76) assayed greater than 1.00 per cent lead and 50.2 grams per tonne silver (Assessment Report 30057).
