This deposit was examined in company with Mr. L.C. Ball, Chief Government Geologist of the Queensland Geological Survey on Wednesday, January 5th, 1944. It has previously been described in some detail by H.G.S. Cribb of the Geological Survey. Since Mr. Cribb's examination was made, the workings southwesterly from the shaft have been extended somewhat, but the owners, Messrs. Elver Bros., at the time of our visit were proposing to abandon that shaft on account of water and the fact that the drives were too long for economic working. The mining method used is expensive, slow and inefficient. Less than 50%, probably only about 30% of the bentonite is recovered by the existing procedure. This report details the origin of the deposits and proposals for future testing.
