A request was made for an estimation of the ore reserves indicated to date in the King Island Scheelite Mine, and for a drilling campaign to be drawn up to prove a total of fifteen years supply of ore at an annual rate of consumption of 200,000 tons. These two matters are dealt with in this report.

In response to a request from Mr. W.H. Williams, Director of Mines, Tasmania, a geological survey was made of the asbestos deposits situated near the tunnel on the Emu Bay railway, 5 miles north-east of Zeehan. A programme of investigation was set out involving a detailed survey of the deposit, prospecting and development work, an assessment of potential fibre grades and ore values, and research into milling practice and market utilization of fibre. The geological survey and related investigation, which are the focus of this report, were concerned mainly with the first three items. Three plates, including a geological map, surface plan, and a plan showing underground workings and effective grades, are attached to this report.

The Pioneer tungsten-bismuth mine, Hatches Creek, was discovered in 1917 and worked on a small scale from then until a short time after the conclusion of World War I, when production ceased owing to a fall in tungsten prices. Prices rose again in 1937, and exploration resumed. The general geology, ore bodies, and working of the Pioneer mine are discussed in this report.
