The Silver Plate SW occurrence is located on a northeast facing slope, north of the head waters of Parker Creek and at an elevation of approximately 680 metres.

The area is underlain by Lower Jurassic Bonanza Group rocks comprising mainly amygdaloidal basalts and lesser silicified andesites and volcanic rocks of the Upper Triassic Karmutsen Formation (Vancouver Group). To the south east these have been intruded by granodiorites of the Early to Middle Jurassic Island Plutonic Suite.

Locally, a quartz vein hosts pyrite with gold and silver values. In 1988, a rock sample (1953) assayed 1.74 grams per tonne gold and 6.8 grams per tonne silver (Assessment Report 17845).

In 1988, Gracey Resources completed a program of rock and soil sampling, geological mapping and 38.0 line-kilometres of combine ground magnetic and electromagnetic surveys on the area immediately north and west as the St. Anthony, Silver Plate and Monte Casino claims. A further 4.0 line-kilometres of combined ground electromagnetic and resistivity surveys were completed the following year.
