The Pink Cadillac claims are located on the north bank of the Bulkley River, 9 kilometres east of Hazelton.

Middle Jurassic to Lower Cretaceous clastic sedimentary rocks of the Bowser Lake Group are intruded by granodiorite dikes of unknown age.

Locally, a quartz vein hosts the rare silver antimony sulphide mineral miargyrite. Berthierite, an iron antimony sulphide, was found in a nearby vein. Arsenopyrite is commonly found disseminated in granodiorite dikes in the area.

In 1983, five samples (J5069 to J5073) from the area yielded from 2600 to 30,000 grams per tonne silver, 0.28 to 2.50 grams per tonne gold and 0.190 to 3.10 per cent antimony (Assessment Report 11900).
