The Younkin showing is located at 1509 metres elevation on the southern slopes of Baldy Mountain, 3.25 kilometres northwest of the Cariboo-Amelia occurrence (082ESW020) of the historic Camp McKinney.

The Younkin showing lies in a complex sequence of volcanic and metasedimentary rocks of the Carboniferous to Permian Anarchist Group. To the north are Cretaceous granitic and granodioritic rocks of the Okanagan batholith. Middle Jurassic granitic rocks of the Nelson intrusions occur to the southwest. 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 refer to the Cariboo-Amelia occurrence (082ESW020).

Flakes of molybdenite were reported found in a 2.5-centimetre wide quartz vein (Bulletin 9 (1940), page 81). The vein was explored by a small shaft.
