Current approved mining operations are located within the Fassifern Seam, which is part of the Boolaroo Formation within the Newcastle Coal Measures. Overlying the Fassifern Seam are the Great Northern, Wallarah and Vales Point seams (and their associated conglomerates and tuffs), which are part of the Moon Island Beach Formation within the Newcastle Coal Measures. Historically, mining has occurred within one or more of the Wallarah, Great Northern and Fassifern seams at the various mines throughout the Lake Macquarie region.The coal resource within the Fassifern Seam has a low sulphur content, which makes it suitable for both export and domestic power generation markets. Within the approved mining area, the Fassifern Seam lies at depth of around 150 to 210 metres (based on known and inferred contour data). The Fassifern Seam is approximately 4.5 to 5.5 metres thick, with the immediate roof and floor comprising a tuffaceous claystone of varying hardness. Mining involves the extraction of a 3.5m section of coal (approximate) beneath the A and B plies. The A and B plies, which comprise approximately 1.0 to 1.2 metres of inferior coal, are left on the roof (Seedsman 2011) dependant on mining conditions. Up to approximately 0.8 m coaly shale is left in the floor.The Fassifern seams have been mined at CVC to produce a raw, crushed thermal coal with low sulphur, which is suitable for both export and domestic markets.The Fassifern Seam is mined at a depth of approximately 160 to 200 m, approximately 30 m deeper than the Great Northern Seam, which underlies the Wallarah Seam by approximately 30 m also. The Fassifern Seam is overlain by a tuffaceous claystone material which varies in thickness between 20 and 30 metres. The Fassifern Seam measures up to 5 metres in thickness with roadway development carrying a coal roof and floor.Mining in the Wallarah Seam is complete in the Colliery holding area and mining was discontinued in the late 1990’s. There is still some remaining resource within the Great Northern and Fassifern seams. Current operations and development consent only permits mining within the Fassifern Seam.
