The Lamb showing is located north of Lambly Lake, approximately 20 kilometres north-northwest of Westbank.

The showing is an occurrence of pyrite and chalcopyrite in hornfelsed metasediments of the Devonian-Triassic Harper Ranch Group. In the vicinity of the showing the Harper Ranch rocks are cut by an intrusion of syenite to monzonite composition.

A grab sample of hornfels from the showing assayed 2.4 grams per tonne silver and 0.1925 per cent copper (Assessment Report 17854).

The showing was found in 1988 by Kerr Addison Mines Limited, who carried out an extensive program of prospecting, geological mapping, geochemistry and geophysics in this area. Their focus was a "Hedley" type of gold-bearing skarn, which they were unsuccessful in finding in this area.
