The Jed showing is located about 7 kilometres northwest of the town of Fraser Lake.

The showing was discovered during a regional prospecting program. In 1989 and 1990, a program of prospecting and rock sampling was conducted on the claims.

The area is dominantly underlain by intermediate to felsic intrusions of the Upper Jurassic Francois Lake Intrusive Suite. Volcanic rocks of the Tertiary Endako Group overlie these. The intrusions are host to a number of molybdenite occurrences in the region.

The showing is underlain by quartz monzonite and quartz diorite phases of the northwest trending Francois Lake batholith. Andesite and rhyolite dikes crosscut the batholith.

The main showing is located in the creek gully on the Jed 1 claim. A major shear zone strikes 084 degrees and dips 55 degrees south. A large andesite dike occurs in the hangingwall of the shear zone. Pervasive silicification occurs for about 2 metres in the footwall of the dike. Quartz and clay filled stringers occur in the alteration zone and contain up to 10.9 grams per tonne gold (Assessment Report 20967, sample J24). Pyrite and chalcopyrite were noted in samples of silicified andesite dike.

Erratic values up to 13.6 grams per tonne gold came from altered quartz monzonite with pyrite on the Jed 16 claim (Assessment Report 20967).
