Three Lower Cretaceous Gething Formation (Bullhead Group) coal seams, the Chamberlain, Skeeter and Bird occur in the area in addition to the Lower Cretaceous Gates Formation (Fort St. John Group) seams, all of which occur in a sequence of sandstone, shale, siltstone and conglomerate.

The Chamberlain seam is 0.2 to 6.7 metres thick and decreases in thickness from north to south and also includes a shaly parting 2.5 to 15.2 centimetres thick south of the northern edge of the property. To the south the seam splits and may contain several shale partings. The Skeeter seam is shaly and thin, 0.3 to 2.1 metres, with an average of approximately 0.9 metres. The Bird seam is widely distributed in mineable thicknesses of 0.3 to 5.8 metres over much of the property. It includes rock bands and splits to the south up to 5 splits. In the Chamberlain area it consists of 3 splits with an aggregate thickness of 11.0 metres, a third of which consists of shale bands.

The Gates Formation seams in the Chamberlain area all include large amounts of shaly partings and bands, except for the B seam which is generally clean. Its thickness varies from 0.76 metres to 2.65 metres. The Gates Formation seams generally thicken to the West and South Fork areas (093P 001).

Average volatile matter and ash percentages in washed Chamberlain coal are 22.77 per cent and 6.29 per cent respectively. The Bird seam and the Chamberlain seam show good coking qualities. The Bird seam samples have an average 0.50 per cent sulphur after washing but may retain up to 2.06 per cent sulphur, of which nearly 50 per cent is in the organic form. Limited sampling of the Gates Formation B seam demonstrated volatile matter and ash contents of 28.15 and 7.07 per cent respectively.

The structure in the Chamberlain area consists of a northwest trending syncline/anticline pair, with a major regional syncline to the east. The southwest dipping northwest trending Chamberlain thrust fault cuts the southwest limb of the minor syncline to the west.

Potential reserves in the Bird, Lower Chamberlain and Upper Chamberlain seams calculated to set mining, geological and coal preparation parametres are 180 million tonnes; the Chamberlain seam reserves may, in part, be duplicated in the Sukunka (Bullmoose) deposit (093P 014).
