The Jolly Creek chromite showing is located 11.5 kilometres north of Bridesville. The showing is on the lower slopes of Storm Hill, east of Jolly Creek at about 1219 metres elevation.
The oldest rocks in the vicinity of the Jolly Creek chromite occurrence belong to the Carboniferous to Permian Anarchist Group. Amphibolite, greenstone, quartz chlorite schist, quartz biotite schist and minor serpentinized peridotite comprise lithologies of the Anarchist Group. Penticton Group lithologies outcrop to the east while porphyritic granite, granodiorite and monzonite of the Cretaceous to Tertiary Okanagan batholith are found to the immediate north. Smaller plugs, dikes and sills of biotite granodiorite, quartz diorite and granite of the Middle Jurassic Nelson intrusions crosscut Anarchist Group rocks. Small serpentinite intrusions of uncertain age occur throughout the area and comprise the hostrock of the Jolly Creek chromite occurrence.
The chromite is hosted in a 600 by 100 metre serpentinized peridotite body of uncertain age. Shear-hosted chromite lenses occur in serpentinite. For further details of the typical chromite occurrences of this area refer to the Rock Creek Chromite (082ESW149) and Bridon (082ESW025) occurrences.
