The Sno showing is located at 2300 metres elevation near the ridge of the southwest spur of Snowy Mountain, 1.25 kilometres from the summit. Keremeos is located 18 kilometres to the east-northeast.
The property was once staked as part of the large KS claim block. Parts of the KS claims were subsequently staked by Noranda Explorations Co. Ltd. as the Jen 1 to 81 claims and SR claims in 1972. The claims lapsed in the following year when J. Strebchuk staked the Jon 1 to 4 claims. The only evidence of previous work on the property was an abandoned pit was found on a quartz sericite vein in argillite hostrock. The vein was malachite stained. In 1974, the ground was staked as the Sno 1 to 16 claims by Canadian Occidental Petroleum Ltd.
Regionally, the Sno showing is underlain by argillite and chert of the Carboniferous to Triassic Shoemaker Formation and overlying greenstone, breccia and intrusions of the Carboniferous to Triassic Old Tom Formation. These have been intruded by the Middle Jurassic Similkameen and Jurassic Kruger intrusions.
Locally, the Old Tom Formation was subdivided texturally into massive tuff or basalt, hornblende porphyroblastic greenstone and amphibolite. The Kruger intrusion consists predominantly of a dioritic phase at the Sno showing but lesser porphyritic monzonite is also found. The above rock types are intruded by numerous pegmatite, micropegmatite and microdiorite dikes. Surrounding country rocks have deformed and thermally metamorphosed up to high-grade hornblende hornfels facies by the Similkameen and Kruger intrusions.
Quartz veins, 5 to 20 centimetres wide, occur throughout the property but are most concentrated in the dioritic phase of the Kruger intrusion. Orthoclase, epidote and carbonate are also found. Sulphides within these veins include chalcopyrite, pyrite, molybdenite and sparse galena. Malachite staining is locally common. Skarn is locally developed along the contacts of these two intrusions. The skarn consists of grossular garnet, plagioclase, diopside, epidote, and rare scheelite.
The best copper values, taken during a comprehensive exploration program in 1975, were from samples 27420 and 27421. Sample 27420, of aplite and argillite contact rocks, yielded 0.34 per cent copper (Assessment Report 5676). Sample 27421 yielded 0.64 per cent copper from a quartz vein with chalcopyrite (Assessment Report 5676). The best molybdenum value was from sample 27412, yielding 0.012 per cent molybdenum (Assessment Report 5676). The sample was chert taken from near a contact between chert and diorite. The best tungsten value was sample 27362, yielding 0.016 per cent tungsten (Assessment Report 5676).
