The prospect occurs within the southern part of a belt of rocks known as the Buttle Lake Uplift. The belt is bounded on the east by Upper Triassic Karmutsen Formation volcanics (Vancouver Group) and on the west by Jurassic Island Intrusions.

The geology of the uplift has recently undergone revision and the stratigraphy has been reassigned to several new formations of a redefined Sicker Group and a new Buttle Lake Group (formerly the upper part of the Sicker Group), (Juras, 1987; Massey, personal communication, 1990). See the H-W occurrence (092F 330) for a summary of this revised interpretation.

The occurrence is located in an area that was originally mapped as Middle to Upper Paleozoic Sicker Group volcanics which belong mainly to the old unrevised Myra Formation of Muller (Geological Survey of Canada Paper 79-30). The rocks underlying the property consists of felsic to intermediate flows, tuffs and agglomerates which are overlain to the east by Buttle Lake Group, Azure Lake Formation limestone, lesser chert and argillite.

The Ridge zone quartz vein strikes north, dips steeply and is about 45 centimetres in width. The vein contains arsenopyrite, sphalerite, and galena. A specimen of wallrock consisted of andesite cut by narrow quartz veinlets and carrying similar mineralization. A grab sample of vein material assayed 1.37 grams per tonne gold and 216.00 grams per tonne silver (Assessment Report 1884).
