The Moly occurrence is located north of the Nanaimo Lakes forestry road, between Nanaimo Lakes.

The area is underlain by Upper Triassic Karmutsen Formation (Vancouver Group) porphyritic andesitic to basaltic rocks in contact with Paleozoic Sicker Group argillites and intruded by diorite of the Early to Middle Jurassic Island Plutonic Suite.

The occurrence is underlain by porphyritic basalt of the Karmutsen Formation intruded by a swarm of aplitic to pegmatitic dykes. The pegmatitic dykes grade into dioritic rocks resembling nearby Island Plutonic Suite diorite. Traces of chalcopyrite are associated with minor amounts of disseminated molybdenite in the dykes.

During the years 1963 to 1966, Gunnex Ltd, carried out a regional mapping program with some limited prospecting and silt sampling they completed a list of all known mineral occurrencesin the area. A grab sample of dump material from a pit assayed 0.76 per cent molybdenum (Property File-Report by Laanela). In 1981, Manny Consultants completed a program of soil geochemical sampling on the Nanaimo claim.
