The Stuart showing is located 23 kilometres south-southwest of Vernon, between Wood Lake and Clark Creek.

In this area, east of the Okanagan Valley fault zone, sedimentary and volcanic rocks of the Devonian to Triassic Harper Ranch Group are in probable fault contact with metamorphic rocks. Middle Jurassic granitic plutons of the informally named Terrace Creek batholith intrude the older rocks. Eocene Penticton Group and Miocene volcanic and sedimentary rocks cap areas of older rock.

The basal, partly cemented, well rounded, quartz pebble gravels of Miocene fluvial deposits host placer gold mineralization. The fluvial deposits unconformably overlie Middle Jurassic monzonite and granodiorite and/or volcanic rocks of the Penticton Group. The Miocene sediments are commonly overlain by Miocene basalt flows. The gold is pure (850 fine), of a reddish colour, and is found as flattened pellets up to 2 millimetres in size, with some very fine gold reported. Garnet and a little magnetite occur with the gold.

By 1936, an exploration drift of 30 metres had been completed. Between 1933 and 1945, a total of 2330 grams of placer gold production (refer to 082LSW093) was reported from the Winfield camp (includes 082LSW019, 093 and 142). In 1977-79, Union Oil Company explored the Miocene sediments for uranium. Geological mapping, hydrogeochemical, radiometric, airborne magnetometer and drill programs were conducted.
