Several thin coal seams and one major coal zone with 3.5 metres of coal in a 4.7 metre thick sequence outcrops south of the old Alexandria Ferry. The coal is sub-bituminous "B" and "C" in rank and contains 3.4 per cent to 6.9 per cent moisture, 38.2 per cent to 39.7 per cent volatile matter, 36.8 per cent to 39.7 per cent fixed carbon, and 13.7 per cent to 21.0 per cent ash. The seams dip approximately 15 degrees south. Much of the coal bearing strata has been eroded to the east of the outcrop by a deeply incised preglacial channel.
