The Whiteman showing is located 25 kilometres west-southwest of Vernon, on the steep south side of Whiteman Creek valley.

In this area, Devonian to Triassic sedimentary and volcanic rocks of the Harper Ranch Group are intruded by Middle Jurassic granitic rocks. An Eocene Coryell rhyodacite porphyry to syenite, high-level plug intrudes and is in fault contact with the Middle Jurassic intrusions. Eocene Penticton Group or Kamloops Group volcanic rocks overlie the igneous and sedimentary rocks.

An unaltered, pyritic and limonitic rhyodacite porphyry hosts copper and molybdenum mineralization. Chalcopyrite and molybdenite are reported.

During 1975-77, Canadian Occidental Petroleum Ltd. carried out uranium exploration in the area. In 1978-79, Kennco Explorations Ltd. conducted geological mapping and soil geochemistry surveys.

During 2014 through 2016, the area was held and explored by Ximen Mining Corp. as the Brett Gold property and a complete summary of exploration work can be found at the Brett (MINFILE 082LSW110) occurrence.
