The White occurrence is located at an elevation of approximately 1850 metres, southwest of a small lake on the north side of Whitesaddle Mountain.

The White showing occurs within a complex stack of recumbent folds and imbricated, gently southwest-dipping thrust sheets known as Eastern Waddington thrust belt imbricate zone. The Late Triassic to Cretaceous metamorphic rocks of this imbricate zone consist largely of schist, gneiss and migmatitic rocks; the protlith is comprised of sedimentary and volcanic rock from the Lower Cretaceous Cloud Drifter and Ottarasko and several other formations.

Northeast-directed thrusting placed Upper Triassic (Carnian) and Lower Cretaceous volcanic and sedimentary rocks over Lower Cretaceous (Hauterivian) sedimentary rocks (Geological Survey of Canada Open File 1163, Papers 88-1E, 89-1E; Geology 1991). The thrusting is presumed to have taken place in the Late Cretaceous because the thrusts are cut by quartz diorite and tonalite intrusions dated at 68 million years by the uranium-lead method on zircon (Geological Survey of Canada Paper 88-1E).

Locally, a 10-metre wide, silicified and carbonitized shear zone hosts disseminated chalcopyrite, pyrite and arsenopyrite. A rock sample assayed 0.525 gram per tonne gold (Property File - unknown [1991-08-01]: Property Summary - White Mineral Claim Group). A granodioritic stock of the Late Cretaceous to Paleocene Bendor Suite intrudes the Eastern Waddington thrust belt imbricate zone. The White showing occurs near the periphery of the stock.

In 1991, the area was staked and prospected as the White claims by R. Durfeld and J. Deighton.
