The Skeena D coal occurrence is located on the west bank of the Skeena River, 8 kilometres above the junction with Kispiox Village.
The host rocks are folded and deformed shales, greywackes and conglomerates of the Lower Cretaceous Kitsuns Creek Formation, Skeena Group.
Two seams, generally 0.2 metres to 0.3 metres thick but structurally thickened locally, are present. A representative sample contains 7.6 per cent moisture, 30.9 per cent ash, 19.0 per cent volatile matter and 42.5 per cent fixed carbon (Geological Survey of Canada Memoir 223 (1954), page 133).
