The Ewin Creek occurrence is located approximately 15.5 kilometres northeast of Elkford, BC.

Over twelve coal seams, up to 13.01 metres thick, occur in the Jurassic-Cretaceous Mist Mountain Formation (Kootenay Group) interbedded with sandstone, siltstone, mudstone and minor conglomerate. The coal licences lay on the eastern limb of the Fording River syncline (Alexander Creek syncline) which trends roughly north and plunges south. Beds strike approximately north and dip 30 to 50 degrees west. Four westerly dipping thrust faults are projected through the licence area.

The #3 seam is the lowest major seam in the section, and can be divided into 3 seam (approximately 2.17 to 3.95 metres) and 3L seam (approximately 1.40 to 3.12 metres, both low volatile bituminous in rank, separated by a rock split approximately 0.89 to 2.42 metres thick). The coal contains 18.8 to 20.8 per cent volatile matter and 79.4 to 80.2 per cent fixed carbon on a dry ash-free basis. Coal may be clean or may contain rock partings. The #4 seam (4.11 to 5.64 metres) is low volatile bituminous in rank with volatile matter and fixed carbon ranging from 20.8 to 21.2 per cent and 78.9 to 79.2 per cent respectively (dried air free basis). Two or three rock partings occur in the #4 seam. The #5 seam is the thickest seam found on the licences (15.27 to 8.31 metres). It is of medium volatile bituminous rank and contains numerous mudstone splits in the upper few metres. Thickness decreases to the north. Volatile matter and fixed carbon content range from 22.8 to 25.3 per cent, and 74.7 to 77.2 per cent respectively (dried air free basis). The #6 seam is 4.42 metres thick on Imperial Ridge (where it contains a 1.07 metre rock parting) and it thins and pinches out to the south. The #7 seam is approximately 4.29 to 2.95 metres thick. The #8 seam is approximately 3.43 to 5.30 metres thick and the #10 seam is 5.05 to 5.12 metres thick. Five seams of thicknesses 1.77 to 3.91 metres occur above the #10 seam (Coal Assessment Report 286).

Work completed by Kaiser Resources Ltd. and BC Coal Ltd. from 1978 through 1981 included geological mapping, hand trenching, outcrop sampling, driving of adits, diamond drilling, core sampling, and coal analyses (Coal Assessment Reports 284, 285, 286).

The estimated (inferred) total in-place coal reserves at Ewin Creek are 500 million tonnes, of which approximately 60 per cent occur under less than 750 metres of cover (Coal Assessment Report 286).
