The Beaver Creek occurrence is located on an informally named tributary (Beaver Creek) of Tommy Jack Creek (Assessment Report 19581).

The regional geology is similar to that of the Tommy Jack occurrence (refer to 094D 031).

Thin coal beds are known to outcrop in Beaver Creek and its tributaries. Plant fossils and poorly preserved pelecypods are common in the shales, argillites and siltstones which host the coal. The rocks are part of the Middle to Upper Jurassic Bowser Lake Group. Other rock types are: siltstones, arkosic sandstones and minor conglomerates. The general strike of the bedding is northwest to northeast, dipping gently to the west.

Small granodiorite and dacite dykes and sills intrude the sediments and are possibly related to and/or contemporaneous with the Cretaceous Bulkley Intrusions which occur further to the south (Assessment Report 19581).
