Abstract

Eleven scout drill holes entailing 1290 feet of drilling were sunk to find suitable open-cut prospecting areas for the Young Wallsend Seam of the "Upper" Coal Measures within an area of one square mile in Portion 10, Parish of Hexham, Newcastle Region, N.S.W. Several drill holes intersected the Dudley (?) and Yard Seams overlying the Young Wallsend Seam. The scout drilling defined the following inferred reserves of coal: [see record for table data]. These figures do not take into account weathering and possible worked-out areas which may reduce the reserves by as much as 30%. The seams are banded and the quality of the coal could probably be improved considerably by washing. The scout drilling did not define accurately the overburden ratios; however, it is likely that overburden to coal ratio for the Dudley (?) Seam will average very roughly 5:1 and for Young Wallsend about 9:1 if the Dudley is mined beforehand where it overlies the Young Wallsend. These results did not justify commencing a "testing and defining" drilling programme. The Yard Seam was not investigated in detail; its thinness precludes it from having any importance for open-cut mining.
