The Norma showing is located about 105 kilometres northeast of the community of Dease Lake.

A tetrahedrite-bearing quartz vein is reported to occur in dolomite. The area is underlain by Upper Silurian to Middle Devonian (Givetian) sedimentary rock consisting of sandstone, dolomite and limestone, possible of the Ramhorn or McDame groups. A sample across about 90 centimetres of vein on the Norma 3 claim yielded a trace of gold, 2880.02 grams per tonne silver and 7.65 per cent copper (Property File - Hennel, 1973). A "pyrite showing" of undescribed character assayed trace gold, 17.14 grams per tonne silver and 0.05 per cent copper (Property File - Hennel, 1973).

In 2005, an airborne magnetic and electromagnetic survey totalling 2130 line kilometres was flown over the Thrust property on behalf of United Exploration Management Inc. The property covers several showings: Canyon (104I 013), Wolf (Cub) (104I 024), Ewe (104I 025), Johnny (104I 040), Erna (104I 057), Norma (104I 058), May (104I 070) and Eliza (104I 099).
