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

The 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 wide. Locally, closely spaced sulphide bands occur over a 3 to 3.6 metre width.

Drillholes 11 and 12 in Pit L intersected a zone of mineralization 3.6 metres thick, in which individual sulphide bands 0.9 to 1.2 metres wide assayed from 0.5 to 2.9 per cent combined lead-zinc (Property File - Map of Trenches and Diamond Drill Holes on Claims near Sicamous, 1966).

In 1998, Equity Engineering Ltd. completed a trenching and drilling program to explore soil geochemical and VLF-EM anomalies identified in 1996. A chip sample from the Borrow Pit area graded 0.78 percent lead and 33.6 grams per tonne silver over 2 metres (Williams, D. (2011-10-28): Technical Report on the Shuswap Silver Property). The drill program totalled 732.4 metres between 4 holes. Highlighted results were one massive sulphide zone grading 3.83 percent lead and zinc combined, and 15.2 grams per tonne silver over 0.86 metres (Williams, D. (2011-10-28): Technical Report on the Shuswap Silver Property).

In 2008, Misty Creek Ventures Ltd. and Equity Exploration Consultants Ltd. (formerly Equity Engineering Ltd.) completed a small exploration program of geological mapping and rock sampling. Highlights include sample 113389, which assayed 16.45 per cent lead, 1.73 per cent zinc and 73.4 grams per tonne silver (Assessment Report 30417).

In 2011, MatNic Resources Inc. completed airborne VTEM and magnetometer geophysical surveys, prospecting and rock, silt and soil sampling. Highlights include chip sample 545568, which assayed 0.16 per cent copper, 3.51 per cent lead, 8.73 per cent zinc and 20.9 grams per tonne silver over a 40 by 20 centimetre area (Assessment Report 32490).

In 2012, MatNic Resources Inc. completed a three-hole diamond drill program. Highlights include drillhole SS12-003, which returned 6 metres grading 1.003 per cent lead, 0.9225 per cent zinc and 10.25 grams per tonne silver (Press Release, MatNic Resources Inc., November 27, 2012).
