The Ascot occurrence is located on the southern slope of Mount Woodside, at an elevation of approximately 150 metres.
The area is underlain by Lower and Middle Jurassic Harrison Lake Formation andesites, andesite porphyry, andesite breccia and basalt. Felsic volcanics and intrusions of Tertiary quartz diorite are also reported in this area.
The volcanic rocks are locally silicified and mineralized with sulphides, primarily pyrite. Minor amounts of chalcopyrite and a trace of sphalerite are associated with quartz stringers striking west-northwest and dipping steeply northeast in altered siliceous volcanic rock, reported variably as agglomerate or andesite flow breccia. A film of chalcocite coats the other sulphides where the stringers are vuggy. These sulphides also occur in small amounts in the country rock together with heavy concentrations of pyrite.
In the same vicinity, chalcopyrite is reported to occur in a shear in porphyritic andesite. The shear is 15 centimetres wide, strikes 110 degrees, dips 65 degrees southwest and is parallel to a band of grey, cherty pyritic rock approximately 3 metres wide.
In 1981, a sample (8978) of a sulphide-rich gossan zone yielded 0.35 per cent copper and less than 0.1 gram per tonne gold. A previous sample from this location, reported by A.S. Allen in 1965, assayed 0.20 per cent copper, 7.5 grams per tonne silver, 0.35 per cent lead and 3.77 per cent zinc (Assessment Report 9640).
The area was explored by Ascot Mines in 1965. During 1971 and 1972, GeoQuest Consulting completed a program of silt and soil sampling, geological mapping and prospecting on the area as the Fab claims. In 1981, Invermay Resources conducted soil and rock sampling in the area as the Treblif claims. In 2008, Bold View Resources completed a program of rock and soil sampling on the area as the Cupro property. In 2013, the area was prospected by A. Reimer as the Camp Scout claims.
