The Gold Mountain showing is located 21 kilometres northeast of Vernon, near the headwaters of Putnam Creek.
In the area, Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks are faulted over metasedimentary rocks of the Proterozoic Silver Creek Formation.
Nicola Group argillite hosts gold and copper mineralization in a 1.5 metre thick quartz vein. Copper mineralization, probably chalcopyrite, is present. Sampling from underground exploration returned gold values of 27 grams per tonne (Minister of Mines Annual Report 1902, page 188).
The first reference to this occurrence is from the 1902 Annual Report.
