The Deer showing is located 10 kilometres southeast of Vernon, west of Deer 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 of the Shuswap Terrane. Middle Jurassic granite plutons intrude the older rocks. Eocene Penticton Group and Miocene Chilcotin Group 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 extend over a 4000 by 800 by 50 metre area and include the Rim Rocks (082LSW135) and King Edward (082LSW090) showings.

The fluvial deposits, unconformably overlying metamorphic rocks and Middle Jurassic granitic rocks and pegmatite, are generally overlain by Miocene basalts.

Two exploration adits are located at the base of the Miocene sediments. In 1977, Kerr Addison Mines Ltd. explored the Miocene sediments for uranium. Geological mapping, hydrogeochemical and drill programs were conducted. In 1978-79, Banqwest Resources Ltd. carried out geological mapping, hydrogeochemical, soil geochemical, radiometric and trenching programs.
