The Corbin (Middle Mountain) occurrence is located approximately 33 kilometres east of Fernie, and approximately 6.5 kilometres west of the British Columbia-Alberta border.

Only the lower portion of the Jurassic-Cretaceous Mist Mountain Formation (Kootenay Group) is present in the Corbin (Middle Mountain) occurrence area and it is subdivided into the coal-bearing Mammoth seam and the upper sandstone and shale series. The lower Mammoth seam (up to 58 metres thick) consists of claystone with thin, discontinuous lenses and interbeds of coal and stony coal. The upper Mammoth seam (up to 35 metres thick) contains coal with discontinuous lenses and interbeds of claystone. The coal is estimated to be of medium volatile bituminous rank.

In the southeast corner of the licence, the Mammoth seam has been thrust repeated and as this is the only in-place coal occurrence on the property, open pit potential is confined to this area. Tonnages of coal are expected to be small.

The main fold structure consists of a north trending, south plunging (approximately 35 degrees) anticline-syncline pair which outcrops near the eastern boundary of the property. To the southwest of the folds are two northwest trending, west dipping thrust faults. The west side of the property consists of a series of west dipping, northwest trending high angle reverse faults.

Fording River Operations conducted a geophysical program in 1997 (Exploration and Mining in BC 1997), and a modest drilling program in 1998 (Exploration and Mining in BC 1998).

The Corbin (Middle Mountain) occurrence lies near the northern extent of the mine operations of Coal Mountain (MINFILE 082GNE001).
