The Cub occurrence is located on the eastern slope of Cornwall Creek, approximately 6.5 kilometres southwest of the community of Cache Creek.

The area is underlain by a long, relatively narrow, northwesterly trending belt of volcanics and sediments belonging to the Upper Triassic Nicola Group.

Locally, there are pyritic andesites in a gossanous zone and float boulders of listwanite containing banded quartz veins.

In 1991, the Cub claim was staked by Teck Exploration to cover a pyritic gossan. A program of geochemical sampling, geological mapping and geophysical surveys (VLF-EM and magnetometer) was completed in 1991 and in 1994. In 1991, sampling of the pyritic gossan returned up to 175 parts per million copper (Assessment Report 22477).
