The Upper Whiteman Creek showing is located 28 kilometres west of Vernon, on the south side of Whiteman Creek.

In this area, Devonian to Triassic sedimentary and volcanic rocks of the Harper Ranch Group are intruded by Middle Jurassic granitic rocks. Eocene Penticton Group or Kamloops Group volcanic rocks overlie the igneous and sedimentary rocks. Eocene Coryell rhyodacite porphyry to syenite plugs and dikes intrude these rocks.

Quaternary or older fluvial gravels host placer gold mineralization. Well-worn flake gold was panned from a partly consolidated paleochannel about 20 metres above the present creek level.
