The Adair showing is located at the head of La Forme Creek, approximately 28 kilometres northeast of Revelstoke. The Lead King (MINFILE 082M 094) prospect is located 1400 metres to the west- northwest.

Prospecting work of the Adair showings commenced sometime in the early 1890’s. The Adair (or Eureka) Group was Crown Granted in 1910. The Adair showings subsequently became ‘“lost”’ due to slides carrying waste dumps from the workings, the adit portal being partly covered over, and the area being densely overgrown with slide alder. The Adair adit was rediscovered in 1988 by prospectors Cameron and Jenkins after several years of detailed prospecting in the area. In 1989, Teck Corporation mapped and sampled the adit in detail. The Adair Group and reverted crown granted claims between Lead King and Mastodon were acquired by Le Mans Resources Ltd., in the 1970’s. Reconnaissance geochemical surveys and geological sketch mapping were done in 1975 and 1977. In 2008 to 2010, Rich River Exploration Ltd. performed a series of geochemical and geological surveys of showing as a part of their Allco-Redtop-Slide project.

The area is underlain by Lower Cambrian limestone and dolomite of the Badshot Formation in contact, both east and west, with dark -grey and green phyllites of the Lower Cambrian and younger Lardeau Group.

Locally, a 0.6 metre wide vein, mineralized with chalcopyrite, is exposed in former underground workings and trenches.
