Six scout drilling holes totalling 1020 feet of drilling were sunk by the Bureau in the Stony Pinch and Thornton Area, about 6 miles south-south-east of the City of Maitland in the Hunter Valley of N.S.W. The bores penetrated the Four Mile Creek beds and the Buttai Sandstone of the Tomago "Stage" of the "Upper" Coal Measures. In the absence of reliable stratigraphical control, the seams cannot be correlated with much certainty. Bore BMR 4 Stony Punch indicated that Donaldson's Seam(?) is thin and much banded; the coal, excluding bands, has an ash content of about 15% and calorific value of 12,300 B.Th.U/lb. This same bore showed that the basal 7 feet 3 inches of the Big Ben Seam had an ash content of about 25% and calorific value of 10,600 B.Th.U/lb. if 8 inches of non-coal bands are excluded. The general results of the drilling were that the coal seams were heavily banded, variable and high in inherent ash. Accordingly the prospecting was halted after drilling six holes.
