Precambrian-Paleozoic(?) Monashee Complex rocks are exposed at the Victor Lake North showing where pegmatites in pelitic schists are reported to contain andalusite crystals as large as 4 by 3 centimetres in size. In this area, quartz veins containing bright blue kyanite blades up to 6 centimetres long, are also common.

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.
