During late 1951 and early 1952 the Bureau, while searching for open-cut coal in New South Wales, prospected the Big Ben and Donaldson's Seams in the Bloomfield Area which is 3.5 miles south of East Maitland. Drilling involving 21 holes and totalling about 2400 ft. revealed that although the actual coal of the seams was quite good in parts, the seams themselves were subject to marked bending, thinning, and splitting. This not only severely limits open-cut prospects to small areas but will make mining difficult. In the contiguous East Bloomfield, Stoney Pinch and Thornton Areas an additional 16 holes with a total footage of 2,250 feet were drilled and indicated that the seams were characterised by the same rapid variation and offer no better possibilities than the main Bloomfield Area. Operations, including mining, coal analyses, logging, and surveying are discussed. Bore logs and the results of coal sample analyses are appended to this report.
