The Stan occurrence is located at 1189 metres elevation between Stanhope and Jolly creeks, 1 kilometre north of the Lemon occurrence (082ESW223). Bridesville, British Columbia lies 11 kilometres to the south.

Regionally, the Stan occurrence is hosted by a sequence of metavolcanic and metasedimentary rocks of the Permian to Carboniferous Anarchist Group. To the north are granite and granodiorite of the Okanagan batholith. Granite of the Middle Jurassic Nelson intrusions occurs to the southwest. Eocene Penticton Group volcanic and sedimentary rocks overlie locally sheared amphibolite and serpentinite bodies to the east. For a more detailed description of the geology refer to the Victoria occurrence (082ESW021).

Locally, the best outcrops are located along Stanhope Creek immediately west of the Stan occurrence. These outcrops are considered to belong to the Anarchist Group consisting of siliceous metasediments and metadiorite. The metasediments are fine to medium grained, light grey, poorly foliated and contain quartz, potassium feldspar and plagioclase. Chlorite and biotite comprise minor mafic constituents. Quartz and calcite veinlets are common. The metadiorite is similar in appearance but is locally coarser grained and contains more plagioclase and minor hornblende. A gabbro or diabase dike is thought to form, in part, the hostrock of the Stan occurrence.

The Stan occurrence consists of a number of quartz veins occurring along the contact between the diabase dike and adjacent metadiorite. The veins contain disseminated pyrite and minor chalcopyrite and are strongly oxidized. The veins are discontinuous and lensy. Along narrower sections, the metadiorite wallrock is brecciated.

Twelve rock samples were taken from these veins as part of an exploration program in 1981 by K. Heffernan. Several samples yielded anomalous silver. Sample 11-81-07, a 0.19-metre chip sample from brecciated footwall metadiorite, assayed 11.2 grams per tonne silver (Assessment Report 10734). Similarly, sample 11-81-08, a grab from a quartz lens with minor disseminated pyrite yielded 15.9 grams per tonne silver (Assessment Report 10743). A 0.11-metre chip (Sample 11-81-09) from siliceous metadiorite in the hangingwall assayed 15.2 grams per tonne silver (Assessment Report 10734). Sample 11-81-01 yielded 0.192 per cent copper and 6.6 grams per tonne silver from a brecciated quartz vein with disseminated pyrite and chalcopyrite (Assessment Report 10734). Gold, lead and zinc results were poor.
