A northwest trending narrow belt of Paleozoic metasedimentary rocks consisting of micaceous quartzite and crystalline limestone is bounded to the east by granodiorite and to the west by diorite of the Coast Plutonic Complex. The metasediments are highly folded and faulted.

A scheelite-bearing zone in skarn occurs near the limestone- granodiorite contact. Disseminated scheelite grains occur in a steep dipping diopside-bearing skarn which is several metres wide and trends for about 5 metres. A sample assayed 0.36 per cent tungsten oxide and 0.72 per cent zinc (Assessment Report 14537).
