The Sharon occurrence is located on the north side of Woodbury Creek, approximately 2.7 kilometres northwest of its mouth on Kootenay Lake.

The area is underlain by mudstone, siltstone, shale and fine clastic sedimentary rocks of the Cambrian to Devonian Index Formation (Lardeau Group), which are overlain by limestone, slate, siltstone and argillite of the Upper Mississippian to Permian Milford Formation.

Locally, the western contact of a garnet mica schist and/or calcareous schist unit of the Middle Cambrian to Middle Devonian Index Formation (Lardeau Group) is marked by a sheared and crushed zone, 30 to 60 metres wide, comprised of sheared and crushed dark-grey carbonaceous rock containing scattered pyrite. The zone strikes approximately north-south.

In 1930, a sample assayed 3.8 grams per tonne gold, 54.7 grams per tonne silver and 0.2 per cent copper (Property File - Starr, C.C. [1930-04-24]: Report of Preliminary Examination of the Superior Group).

Three tonnes, taken from this zone in 1964, yielded 964 grams of silver, 699 kilograms of lead and 66 kilograms of zinc.

The area has been explored since the late 1890s in conjunction with the nearby Vigilant (MINFILE 082FNE005) past-producing mine. In 1930, two short caved-in tunnels were reported on the North Branch (L.5825) and Herbert L. (L.5044) Crown grants. In 1957, Cominco examined the area and completed a program of geological mapping. In 1964, minor production was reported.
