Pure, coarsely crystalline quartzite is common among strata of the Precambrian-Paleozoic(?) Monashee Complex. These rocks are free from iron-bearing minerals, appear translucent white in hand specimen, and are so homogeneous as to be almost devoid of internal bedding or lamination. Such quartzite may be a potential source of silica for industrial uses where a high degree of purity is demanded. Near Clanwilliam Lake, relatively pure quartzites occur.

Locally, the area is underlain by calcsilicate metamorphic and paragneiss units of the Proterozoic to Lower Paleozoic Monashee complex.

In 2013, Addie completed an exploration program over the property containing the occurrence including geological mapping and sampling of 21 pegmatite showings. Lepidolite with pink and/or green tourmaline, beryl and rose quartz were identified at these showings.
