The Crook occurrence is located on a small hill, west of the Crooked River and approximately 3 kilometres southwest of the river's mouth on McLeod Lake.

Regionally, the area is underlain by basaltic volcanic rocks of the Mississippian to Permian Antler Formation (Slide Mountain Group).

Locally, a pyritic gossanous andesite hosts anomalous gold values.
