The Sechelt Granite prospect is located on the east side of the Sechelt Peninsula, 1.25 kilometres southwest of Snake Bay.
The Sechelt Peninsula is underlain by diorite and granodiorite of Jurassic age within the Jurassic to Tertiary Coast Plutonic Complex.
The stone at the proposed quarry site, on a steep east facing slope, is reported to be comprised of medium grained gabbro that develops a deep black finish on polishing (Z.D. Hora, Personal Communication, 1991). A hand sample of cut and polished material consisted of fine to medium grained equigranular diorite with up to 5 per cent black minerals in a dark grey plagioclase matrix. Preliminary sampling indicates large blocks ranging from 2 to 5 cubic metres can be extracted from the deposit. Some fracturing is present, but this is reported to decrease to acceptable levels farther into the hillside.
This deposit of black granite is being developed by Sechelt Granite Ltd., an affiliate of Tri-Sil Minerals. The company has been sampling the deposit and carrying out market studies since 1989.
