Capsule Geology

The Lisa showings are located 3 kilometres south-southwest of Darfield and 68 kilometres north of Kamloops, west of the North Thompson River and Highway 5. They are accessible on a secondary road and are about 200 metres north of a farmhouse on Ipsoot Creek (Figure 3, Assessment Report 14292).

Mineralization consists of northwest striking, steeply dipping quartz veins and siliceous zones within shear zones (Assessment Report 14292). Vein widths are reported to be in the 0.6 to 0.9 metre range with mineralized veins present over an area measuring 200 by 120 metres - the long dimension striking northwest. Minerals are reported to be galena, chalcopyrite, pyrite, marcasite and associated secondary malachite, limonite and manganese oxides. Grab samples taken in 1984 from a dump yielded low gold, silver and base metal values, the highest being 8.8 grams per tonne gold, 66.2 grams per tonne silver, 0.16 per cent lead and less than 0.01 per cent zinc (Assessment Report 14292).

The area of the Lisa showings are underlain by metasedimentary rocks of the late Paleozoic Harper Ranch Group which include limestones, siltstones, shales, volcaniclastic sandstones and local volcanic rocks, and volcanic rocks of the Eocene Skull Hill Formation (Kamloops Group). The Skull Hill Formation is composed of dacite, trachyte, basalt, andesite, rhyolite and related breccias (Geological Survey of Canada Memoir 363). Felsite dikes are reported to be present in the area of the showings.

Numerous pits and trenches are evident on the property and are believed to date back to 1912 (Assessment Report 14292). Cosmos Resources Inc. carried out a soil geochemical survey (168 samples analysed for gold, silver and copper) in 1984. In 1986, a four hole diamond drill program (404 metres) was completed on the property (Assessment Report 15784) with disappointing results.
