The Casey Pegmatite occurrence is located at an elevation of approximately 900 metres on a small hill northeast of Casey Lake and approximately 3 kilometres south-southwest of Endako.

The area is underlain primarily by intermediate to felsic intrusions of the Upper Jurassic Francois Lake Intrusive Suite.

Locally, several pegmatite dikes have been identified. The largest dike is 9 metres wide and occurs alongside an aplite dike. The pegmatite consists of quartz, perthitic orthoclase, and minor plagioclase and biotite. Crystal size ranges up to approximately 2.5 centimetres.
