The Kit occurrence is located on the lower, northwestern, slope of Kitsumkalum Mountain, east of Erlandsen Creek.

The area is underlain by sedimentary and volcanic rocks of the Jurassic Hazelton Group, which have been intruded by quartz monzonite and granodiorite and later feldspar quartz porphyry of the Cretaceous to Tertiary Coast Plutonic Complex. The Hazelton rocks are dominantly meta-siltstone and porphyritic andesite with minor meta-greywacke argillite, dacite and basaltic andesite. These rocks have been locally hornfelsed. Distribution of the hornfels generally coincides with zones of molybdenite mineralization.

Locally, minor chalcopyrite, with subordinate molybdenite, occurs in poorly developed quartz vein and fracture systems, occurring in both volcanic and sedimentary host rocks.

In 1967, the area was explored as a part of the Kit claims by Zymont Metals Limited. A sample of disseminated pyrite-chalcopyrite mineralized hornfelsed argillite returned trace silver and 0.05 per cent copper (Property File: Sharp, W.M. (1967-06-26): Summary report - Examination of Kit group).
