The Annis 5 showing is located in the northeast area of the Shuswap Silver property, approximately 20 kilometres northeast of Salmon Arm.

The Shuswap property is underlain by quartzite, micaceous quartzite and quartz-mica schist of the Hadrynian and/or Paleozoic Silver Creek Formation (Mount Ida Group). The mica schists are the most common rock type observed. Muscovite is dominant in these schists; however, lenses rich in biotite and chlorite have been observed. Intercalated with the mica schists are lenses of massive, generally fine-grained, micaceous quartzite. Narrow, granitic and pegmatite dikes are common, cutting the local planes of schistosity in places. Observed schistosity attitudes are variable, with strikes ranging from 070 to 145 degrees and dipping from 40 to 50 degrees to the north.

Within the workings area, the rocks consist of alternating, comparatively thin bands of quartzite and quartz-mica schist. The quartz-mica schist is largely a biotite schist, but bands do occur where the mica is entirely muscovite or muscovite-sericite. In places, this becomes an almost pure muscovite or sericite schist. The rock units are from several centimetres to a couple of tens of metres thick.

Mineralization consists of massive to semi-massive sulphides made up of galena, sphalerite, minor chalcopyrite, pyrite and considerable pyrrhotite. Sulphide bands are found in biotite schist, usually with quartzite, and appear conformable to bedding. These bands vary from several centimetres to 1 metre in width. Locally, closely spaced sulphide bands occur over a 3 to 3.6 metre width.

Grab samples from trench 5 assayed from 1.15 to 1.75 per cent lead, 0.42 to 0.8 per cent zinc and 3.4 to 22.2 grams per tonne silver (Property File - Map of Trenches and Diamond Drill Holes on Claims near Sicamous, 1966).

In 1998, APAC Minerals Inc. and Equity Engineering Ltd. conducted rock chip sampling, trenching and diamond drilling. Highlights include drillhole M98-01, which returned 1.86 metres grading 0.51 per cent lead, 1.75 per cent zinc and 13.2 grams per tonne silver (Assessment Report 25478).
