The Elk occurrence is located at 1349 metres elevation, northwest of the confluence of Wapiti Creek with Rock Creek, and 5.75 kilometres east-southeast of Baldy Mountain. Bridesville, British Columbia lies 12 kilometres to the south.

The Elk occurrence lies within a complex sequence of volcanic and metasedimentary rocks of the Permian to Carboniferous Anarchist Group. To the east, north and west lies granitic and granodioritic rocks of the Cretaceous to Tertiary Okanagan batholith. To the southwest are Middle Jurassic granitic rocks of the Nelson intrusions. Eocene Penticton Group volcanic and sedimentary rocks overlie locally sheared amphibolite and serpentinite bodies of the Anarchist Group to the east. For a more detailed description of the regional geology of the McKinney Camp area refer to the Cariboo-Amelia occurrence (082ESW020).

In 1989, B.R. Stenhouse conducted a reconnaissance geological mapping program on the Elk property. Several areas of mineralogical potential were blast trenched and sampled but no assay results were reported.

Quartzite of the Anarchist Group is the dominant lithology of the Elk occurrence. Andesite and micaceous greenstone of the Anarchist Group are also found on the Elk property. A strong foliation trends subparallel to quartzite bands. Intensely silicified quartzite lenses and quartz veins within quartzite host galena, sphalerite and pyrite mineralization, usually in the central portions. Spotty jarosite and limonite alteration of pyrite are also present. Granitic rocks located on the Elk property include feldspar porphyritic monzonite,

A serpentinite body is located on the northeast corner of the Elk property. Chromite lenses are reported hosted within this serpentinite.
