The Bev showing is located on the eastern side of Skaha Lake, 3 kilometres north of the Dusty Mac occurrence (082ESW078). In 1969, Dusty Chief Mines Ltd. held the ground north of the Dusty Mac to explore for potential extension of gold and silver mineralization onto their claims.
The northern portion of the property is underlain by the Okanagan Gneiss complex. The Okanagan gneiss consists dominantly of strongly foliated, hornblende, biotite granodiorite orthogneiss. The orthogneiss is massive, resistant and weathers medium grey. The strong foliation locally grades to mylonitic gneiss, mylonite and blastomylonite. Minor amphibolite and paragneiss are also present. The gneiss is strongly chloritized along the Okanagan fault. To the south, the Eocene Penticton Group consists of the Kitley Lake Member of the Marron Formation and the overlying White Lake Formation. The Kitley Lake Member consists of massive, yellow to buff, trachyte to trachyandesite. The White Lake Formation consists of light coloured pyroclastic rocks, thick feldspathic andesite lahar deposits, minor andesitic lavas, and minor sandstones and carbonaceous shales.
These units are on the south limb of a southeasterly trending syncline. The beds have variable dips ranging from about 30 to 55 degrees northeast. A strong crossfracture system strikes approximately 010 degrees dipping about 80 degrees westerly almost perpendicular to the synclinal axis.
Line-cutting was done on the claims in 1969 but no record could be found describing any mineralization. Tectonic breccia, silicification, quartz veins and gossan occur at several locations northwest from the Dusty Mac and which may occur on the Bev claims (Bulletin 61, Figure 5.1).
