The Victoria map area, with 149 known mineral occurrences, lies within the Insular Belt, comprising the Wrangellia terrane. The geology consists of rocks belonging to the Paleozoic Sicker and Buttle Lake groups (found within the Cowichan uplift), the Mesozoic Vancouver, Bonanza and Nanaimo groups, the Jurassic to Cretaceous Leech River Complex, the Colquitz and Wark Gneisses of Paleozoic and/or Mesozoic age and the Tertiary Metchosin Volcanics. The strata are intruded by the Early to Middle Jurassic Island Plutonic Suite and the Tertiary Sooke Gabbro. In 1986, a 4-year program of regional mapping was initiated under the Canada-British Columbia Mineral Development Agreement, focusing on the Paleozoic Sicker Group. This work, by N. Massey of the BC Geological Survey, has led to major stratigraphic revisions and associated nomenclature changes.

The Sicker strata are an important exploration target for volcanogenic massive sulphides. They contain past producers such as the Lenora (092B 001), Tyee (092B 002) and Richard III (092B 003) (Mount Sicker deposits), as well as several developed prospects, notably the Lara (092B 129) and the Anita (092B 037) deposits. The Lara has published reserves of 529,000 tonnes, grading 1.11 per cent copper, 1.22 per cent lead, 5.87 per cent zinc, 4.73 grams per tonne gold and 100.1 grams per tonne silver.

 

Deposits underlain by metasediments of the Leech River Complex include the Valentine Mountain prospect (092B 108) where a gold-bearing quartz-vein system hosts reserves (in 1992) of 30,660 tonnes, grading 14.7 grams per tonne gold. During the summer of 1996 a small gravity gold mining plant was erected on the property to test the feasibility of a larger operation. The small mill operated from September 18 to November 22, processing a total of 68 tonnes of ore. The grade was calculated at 9.9 grams per tonne gold, over a 1-metre width. Placer gold, derived from the metasediments, has been mined from the Leech River (092B 078) itself, where a gold rush in the 1860's engaged over 3000 men. Talc occurrences hosted in shear zones within the Leech River rocks were also developed.

 

Several hundred tonnes of ore were mined from the King Solomon (092B 015) and Bluebell (092B 080) skarn deposits which are associated with limestone of the Mount Mark Formation (Buttle Lake Group). A number of skarns are also associated with Quatsino Formation limestone (Vancouver Group).

 

Industrial minerals extensively mined throughout the map area include limestone, granitic rock, sandstone, shale, clay and rhodonite. Manganese was produced at the Hill 60 (092B 027) deposit; rhodonite is still produced there.

 

A province-wide mineral potential study was launched in 1992 with Vancouver Island as the initial study area. Data resulting from this study are available on the Ministry website.
