The West Brazion coal occurrence is located north of Brazion Creek on a broad plateau, about 44 kilometres south-southwest of Chetwynd.

Four main coal seams, the "Discovery" seam and A, B, and C seams, occur in the Lower Cretaceous Gething Formation (Bullhead Group) interbedded with carbonaceous mudstone, sandstone, siltstone, mudstone and minor conglomerate. The structure consists of a series of northwest trending folds to the west of the property. These are cut by an east-southeast trending, north dipping thrust fault. In the centre and east of the property, strata dips gently (less than 10 degrees) to the east-southeast (in the north), and dips to the north-northwest (in the south).

The "Discovery" seam is approximately 4 metres thick, and is clean, bright and blocky, with a number of mudstone partings. Seam A is approximately 0.77 metre thick, and is clean, bright, and blocky. Seam B is approximately 1.84 metres thick with similar characteristics. Seam C is approximately 1.23 metres thick, semi-bright to bright with thin high ash bands (the seam has approximately 33.7 per cent ash).

The coal is medium volatile bituminous with generally low ash (8.91 to 14.24 per cent dried basis, 33.7 per cent in seam C) and high calorific value. Volatile matter ranges from 19.57 to 25.04 per cent dried basis, fixed carbon 46.72 to 70.16 per cent, and sulphur 0.26 to 0.56 per cent dried basis (Coal Assessment Report 687).

In 1978, coal seams were discovered on the West Brazion coal licenses held by Brameda Resources Limited (Amalgamated Brameda-Yukon Limited). During 1979, a grassroots exploration program was carried out to gain knowledge of the structure and stratigraphy of the area, as well as determine the extent and quality of coal seams. The program consisted of geologic mapping and diamond drilling two holes totalling 97 metres with a portable Winkie drill capable of producing AX core.

During the 1979 program, three new seams were discovered when drillhole WB79-1 was drilled. This hole drilled a stratigraphic section above drillhole BW-27 ("Discovery" seam). The three new seams will be known as A, B and C seams, and all four seams discovered to date on the property are quite similar in character (Coal Assessment Report 687).
