The Meares Nickel occurrence is located on the south western side of Lemmens Inlet on Meares Island.

The area is underlain mainly by rocks of the pre-Jurassic Westcoast Complex. This complex is a heterogeneous assemblage of hornblende-plagioclase gneiss, amphibolite, agmatite, basic migmatite, quartz diorite or tonalite and minor metasedimentary and metavolcanic rocks. This complex is considered to be derived from Sicker and Vancouver group rocks which were migmatized in early Jurassic time. Its mobilized granitoid part is thought to have become the source of the Jurassic Island Intrusions.

This nickel-copper deposit, of undetermined size, occurs in a serpentinized ultramafic sill (?) in the Westcoast (Gneiss) Complex. The gneisses are thought to be derived from Sicker Group rocks with the sill being equivalent to basic sills contained in the Sicker Group at other localities on Vancouver Island. These sills are believed to be intrusive equivalents of Karmutsen basalts and are therefore probably Upper Triassic (Geological Survey of Canada Paper 68-50).

It is reported that nickel-copper mineralization associated with pyrrhotite occurs in veinlets or interstitial to olivine and pyroxene. Siegenite is the only nickel-bearing mineral identified, occurring as partly replaced crystals in pyrrhotite.

In 1965, Falconbridge completed a program of soil sampling and a ground magnetometer survey.
