The Seaton coal prospect is located on the west bank of the Bulkley River, 400 metres south of Seaton, approximately 27 kilometres southeast of Hazelton.
The area is underlain by the informally named Eocene Moricetown sediments (Geological Survey of Canada Open File 2322), which strike northwest and dip up to approximately 30 degrees northeast.
Ten or eleven coal seams (0.3 to 1.1 metres thick) occur in a 152 metre section interbedded with shale and sandstone. The main seam (No. 1) is 1.37 metres thick and is split by bands of bone coal. A sample of clean coal from this seam contains 1.8 per cent moisture, 17.7 per cent volatile matter, 36.7 per cent fixed carbon, and 43.8 per cent ash. The No. 2 seam is 0.43 metre thick and contains 3 per cent moisture, 21.2 per cent volatile matter, 59 per cent fixed carbon, and 16.8 per cent ash. The No. 3 seam is 0.9 metre thick, of this 0.71 metre is coal. A sample from this seam contains 1.4 per cent moisture, 19.5 per cent volatile matter, 43.4 per cent fixed carbon, and 35.7 per cent ash.
