Drilling and well completion methods suitable for high yielding production wells in the Upper Series hanging wall sediments have been investigated and 3 successful production wells and series of observation wells have been installed (19 wells totalling 1167 metres). The anticipated consumption rate for industrial water at the present level of development of the mine is 660 ML per year or roughly 2 ML per day. Provided that the rate of deepening of these cuts is compatible, it is highly probable that the twin objectives of provision of an industrial water supply and mine dewatering will be attainable at relatively low cost, possibly without the drilling of any additional production wells for at least 5 years.
