The Coal 1 showing is located 26 kilometres southeast of Lumby and 45 kilometres east-southeast of Vernon.
The property was acquired in 1977 by Union Oil to explore for uranium. In 1977, radiometric and magnetic surveys were done. In 1978, geology, geochemistry and further radiometric and magnetic surveys were completed.
The area is underlain by granodiorite of the Jurassic Nelson Intrusions. These are overlain by plateau basalts with intercalated volcaniclastics of the Miocene Chilcotin Group.
A 1-metre quartz vein occurs in granodiorite near a shear zone. The vein contains traces of fine-grained molybdenite. About 500 metres to the southwest, an outcrop of chloritic, sheared and altered granodiorite contains disseminated pyrite.
