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 were t hough to 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 agglom- erates which are overlain to the east by Buttle Lake Group, Azure Lake Formation limestone, lesser chert and argillite.

The Sugar zone, consisting of 2 parallel veins arranged en echelon plus a third vein intersecting from the west at 045 degrees, strikes northwest and dips 65 to 85 degrees south. The vein has been traced for about 200 metres and has an average width of 30 centimetres. The vein consists of quartz, siderite and calcite and contains arsenopyrite, pyrite and traces of galena and chalcopyrite. A 30 centimetre sample of oxidized vein material contained 10.80 grams per tonne gold and 231.43 grams per tonne silver (Assessment Report 1884).
