The Gold Star showing is located 29 kilometres west of Vernon, on the steep north slope of Whiteman Creek Valley.
The area is underlain by Devonian to Triassic sedimentary and volcanic rocks of the Harper Ranch Group which have been intruded by Middle Jurassic granitic rocks. Eocene Penticton Group and Kamloops Group volcanic rocks overlie the igneous and sedimentary rocks. Eocene Coryell rhyodacite porphyry to syenite plugs and dikes intrude these rocks.
Penticton Group pyritic tuffaceous rocks host gold mineralization. Samples from drilling analysed 2.15 grams per tonne gold and 16 grams per tonne silver over 3.0 metres (Assessment Report 19797).
In 1984-87, Brican Resources Ltd. carried out geological mapping, soil geochemistry, VLF-EM surveys, trenching and drilling. 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.
