The area is underlain mainly by Lower-Middle Jurassic Harrison Lake Formation rocks comprised of volcanic flows, pyroclastics and tuff breccias with minor interbedded volcanic/sedimentary greywacke, tuff and arkose. These rocks are thought to be part of the Middle Jurassic Weaver Lake Member of the Harrison Lake Formation. These are in fault contact with the Upper Jurassic Kent Formation which is comprised of chert, interbedded tuffs and volcanic flow rocks which resemble the Weaver Lake Member suite.

A strong, northeast trending zone of hydrothermal alteration extending for about 350 metres, pervades the rocks in the Valley View zone. The alteration consists of chlorite, locally strong sericite, lesser epidote with some pervasive feldspar (albite?) and quartz. Disseminated pyrite occurs throughout the alteration zone with much lesser pyrrhotite. Southeast trending and vertical to steeply dipping mineralized open space quartz-sericite-carbonate-epidote veins are superimposed on the alteration zones. These veins extend over several centimetres and are mineralized with coarse crystalline pyrite, minor chalcopyrite, sphalerite and galena yielding trace silver and gold values.

A second zone of significant hydrothermal alteration and mineralization is located along the lower reaches of Stacey Creek, and extends for about 45 metres along the stream bank. The altered zone occurs in siliceous chert, arkose and breccias which have undergone extensive sericitic and local brecciation with strong silica and feldspar impregnation and veining. An irregular vein of barite about 0.5 metre wide, occurs in the intensely sericitic (pyrophyllite) brecciated alteration zone. Minor sulphide mineralization consisting of pyrite, chalcopyrite, galena and sphalerite occurs locally in association with sericitic and siliceous alteration.

The significant differences between the Stacey Creek (Constantine) zone and the Valley View zone is the more intense sericitic (pyrophyllite) alteration, stronger brecciation and much less disseminated pyrite and other sulphides.

Selected samples from the mineralized zones were collected in 1984. A sample from a mineralized vein hosting pyrite and chalcopyrite assayed 0.064 per cent copper, 28.11 grams per tonne silver and 0.034 gram per tonne gold. A chip sample from a mineralized, siliceous feldspathic fragmental rock from Stacey Creek analysed 0.138 per cent copper, 0.86 per cent lead, 0.30 per cent zinc, 2.9 grams per tonne silver and 0.001 gram per tonne gold. Another 0.5 metre chip sample from sericitized, weakly silicified breccia that is crosscut by barite veinlets, analysed 0.087 per cent copper, 0.126 per cent lead, 0.364 per cent zinc, 10.4 grams per tonne silver and 0.014 gram per tonne gold. A 0.5 metre chip sample of sulphide mineralization from this area yielded 0.295 per cent copper, 0.90 per cent lead, 1.40 per cent zinc, 30.0 grams per tonne silver and 0.45 gram per tonne gold (Assessment Report 12222).

A small shipment was made in 1961.
