The Mahood Lake showing is located on the top of a bluff on the south shore of Mahood Lake, within greenstone of the Devonian-Permian Fennell Formation of the Slide Mountain Group. An assay of a sample that analysed 20.6 grams per tonne gold, 34 grams per tonne silver and 0.3 per cent copper was reported in the Minister of Mines Annual Report 1924. The claims around the "auriferous ledge" showing are mentioned in many of the Annual Reports of the late 1800s and early 1900s, but information on the history of work is not available.
