The PEG occurrence is located on the ridge north of the Diversion River and east of Walker Creek.

The area is underlain by metasandstone, metapelite and amphibolite of the Jurassic to Cretaceous Leech River Complex (Formation). These units have been subsequently intruded by a large quartz diorite sill and small pegmatite dykes and sills, of Tertiary age.

Scattered, sparse sulphide mineralization found in the area consists of pyrite, chalcopyrite and bornite, and is largely confined to the siliceous alteration zones, brecciated zones and rusty seep zones within the amphibolite unit. There is reported to be good correlation between the occurrence of rhodochrosite and copper mineralization.

Beryl, tourmaline, apatite, spinel and feldspar are reported to occur in two pegmatite veins in the area.

In 1977 through 1997, Beau Pre Explorations completed various programs of prospecting, geochemical sampling and geological mapping on the area as the PEG claim, apart of the Valentine Mountain (MINFILE 092B 108) property. In 1989, continuous rock chip samples produced values of 0.67 per cent copper over 20 centimetres and 0.28 per cent copper over 30 centimetres (Assessment Report 19358).
