The Victoria prospect is situated on the southeast bank of Winters Creek (16 Mile Creek), 2 kilometres northeast of the Similkameen River.

The area is underlain by rocks of the Ordovician to Triassic Apex Mountain Complex. They are represented by a highly deformed package of cherts, argillites, tuffaceous siltstones, greenstones and minor limestones, originally subdivided into the Independence, Bradshaw, Old Tom and Shoemaker formations. In 1984, these formations were grouped into the Apex Mountain Complex and Upper Devonian, Carboniferous and Middle to Late Triassic microfossils have been recovered from some of the units within the complex. The relationship between the complex and the supracrustal rock units of the Nicola Group, further to the west, is uncertain, however, the Apex Mountain Complex is believed to represent a highly deformed ophiolite complex that formed above an east-dipping subduction zone (Milford, 1984).

A small, elongate northeast-trending body of granodiorite of unknown age outcrops over a 500 by 250 metre area, and intrudes Apex Mountain argillite, which underlies much of the southeastern bank of Winters Creek. A single quartz vein striking 140 to 150 degrees and dipping steeply southwest cuts both the granodiorite and the surrounding argillite. The vein has been explored by 3 adits over a strike length of 187 metres and a vertical distance of 116 metres. The 0.02 to 0.66-metre wide vein is segmented by several crossfaults in the underground workings.

The vein is composed of vitreous crystalline quartz containing arsenopyrite, pyrite, pyrrhotite, chalcopyrite, and occasional seams and patches of chloritic material. The distribution of the sulphides in the vein is quite irregular. Arsenopyrite forms 25 to 50 percent of the vein matter as lenses and seams in the lowermost adit to the northwest, the No. 1 adit. A selected sample of arsenopyrite assayed 4.5 grams per tonne gold and 8.6 grams per tonne silver (Minister of Mines Annual Report 1936, page D12). Sulphides form a low percentage of the vein in the No. 2 adit to the southeast. A chip sample of the face of the No. 2 adit, across 66 centimetres of quartz, assayed 9.6 grams per tonne gold and 10 grams per tonne silver (Minister of Mines Annual Report 1936, page D12).

This prospect was explored by trenching and 95 metres of tunnelling between 1899 and 1936 by various private owners.
