In the Triassic coal measures of Telford Basin occurring 1000 + (?) feet stratigraphically above the main (Telfod) seam are a number of coal seams - the "Upper coal series" - which further add to the opencut coal reserves at Leigh Creek Coalfield. Within certain limits, defined elsewhere, 3.58 million tons of coal will be available for open cut mining, having an overall weighted average ash content of 14.61% a sulphur content of 0.4% and calorific value 8,260 B.T.U./lb. (all referred to standard 12% moisture basis). The coal occurs in a number of seams but possibly only three of these will be amenable to full extraction. Ultimately the thickest sections of several other low-ash seams might be recovered - these have not been included in the above reserves. On the basis of ash content and calorific value the coal is the best discovered in the Telford Basin. The presence of sand and thick partings and the steep dip of the seams will present problems to the mining authority not previously encountered at Leigh Creek.
