The Camp area is underlain by a massive sequence of pillowed andesite basalt flows along with agglomeratic phases of the Upper Triassic Stuhini Group. This volcanic package has been intruded by small rhyolite plugs in the southern half of the property. The only sedimentary rocks noted in the VG area are narrow (50 to 100 metres) beds of coarsely crystalline marble.
In the Camp area, white quartz containing up to 30 per cent pyrite and traces of galena occupies pillow selvages in the massive andesite at the J34 trench. Mineralized quartz is up to 30 centimeters thick and assays up to 411.43 grams per tonne silver 4.13 grams per tonne gold with small amounts of base metals (Assessment Report 20459). Although this mineralization is stratabound, the lack of base metals at the J34 showing and the local pattern of gold, silver and lead in soils indicates that the Camp zone mineralization is related to the Camp Zone fault.
Massive andesite bluffs were sparsely mineralized with small veinlets and concentrations of pyrite with minor sphalerite.
At the DN2 trench, disseminated pyrite in chloritic andesite boulders graded up 8.23 grams per tonne gold with no significant base-metal values (Assessment Report 20459). Although the local source of the boulders was not found, it was assumed that it was close by, near the Mineral Gulch Fault plane.
In the Mineral Gulch area, massive and disseminated sphalerite with minor galena and trace amounts of pyrite occur in quartz lenses in massive andesite just below its contact with porphyritic andesite. These mineralized quartz lenses are up to 3 metres long and 10 centimetres thick. They occupy flow-top planes and pillow selvages. Assays from samples of this mineralization return up to 21.5 per cent zinc and 6.88 per cent lead with minor amounts of copper and very low precious metal values (Assessment Report 20459). Samples of massive fine-grained purple sphalerite mineralization and disseminated coarse-grained yellow sphalerite in quartz return similar zinc-assay concentrations.
