The Shaw Creek showing is located on the creek north of Cowichan Lake. The showing is located on the Flight claims, see also 092F 563.

Lenses of manganese silicates, mainly rhodonite, occur in highly folded red and white cherty tuffs of the Mississippian to Pennsylvanian Fourth Lake Formation, Buttle Lake Group. The lenses, which appear conformable, are occasionally coated with hard, black siliceous oxide.

The mineralization is exposed over an area measuring 100 by 30 metres. Three-metre samples assayed from 22.2 to 40.8 per cent manganese and 30 to 57 per cent silica (Minister of Mines Annual Report, 1918). In 2007, two rock chip samples yielded values of 45.78 and 44.73 per cent magnesium oxide over 0.3 metres (Assessment Report 29700).

Tests in 1940 showed samples contained pyrolusite, rhodochrosite and rhodonite, which are the oxide, carbonate and silicate of manganese, respectively. The manganese is often finely divided and associated with a highly siliceous gangue.

The occurrence was first discovered in 1919. In 1987, Utah Mines Limited completed a program of rock, soil and silt sampling. In 2007, American Manganese Inc. completed a program of soil and rock sampling on the Black Prince property.
