The CY 2 East occurrence is located west of McCormick Creek at an elevation of approximately 1100 metres.
Regionally, the area is underlain by quartzites, pelites, phyllites, limestone and argillites of the Cambrian Laib Formation and basaltic volcanic rocks of the Lower Jurassic Elise Formation (Rossland Group), which have been intruded by granodioritic rocks of the Cretaceous Anstey pluton to the northeast.
Locally, quartz veins, up to 10-centimtres wide, host pyrrhotite, pyrite, galena and chalcopyrite mineralization associated with a 30-centimetre wide shear zone and a carbonate-altered dike. Limonite and iron carbonate alteration minerals are also reported. The mineralization is hosted by phyllitic sediments and argillite. The dike strikes 030 degrees, whereas the shear zone strikes 110 degrees and dips 60 degrees southwest.
In 2003, a sample (BH-42) of gouge material assayed greater than 0.999 per cent lead, 0.195 per cent zinc, 32.8 grams per tonne silver and 2.74 grams per tonne gold (Assessment Report 27231).
The area has been historically explored since the late 1800s in conjunction with the nearby Bunker Hill (MINFILE 082FSW002) and Red Rock (MINFILE 082FSW025) past-producing mines.
In 1971, Abella Resources Ltd. mapped and soil sampled the area as the Ness claims. In 1983, Rex Silver Mines Ltd. completed a program of rock, silt and soil sampling; geological mapping and a ground electromagnetic survey on the area as the Waneta 1-10 claims. In 1985, Noranda Mining and Exploration Inc. completed a program of rock and silt sampling, geological mapping and ground geophysical surveys on the area as the Swift 10 claim.
During 1988 through 1990, International Corona Corp. completed programs of soil and silt sampling, geological mapping and a 2660.0 line-kilometre airborne geophysical survey on the area as the Elise 1-61 claims.
During 1997 through 2002, William Howard completed programs of rock and soil sampling, geological mapping and a 5.2 line-kilometre ground electromagnetic survey on the area as the Cly property.
