Abstract
THE “Mining Review” of the Department of Mines of South Australia for the half-year ending June 30, 1934, shows that there has been considerable activity in gold mining, due, of course, to the increase in the value of the product. Thus the quantity of gold obtained in 1933 was slightly more than, double that obtained in 1932, but its value was considerably more than double that obtained in the previous year, being in fact approximately in the proportion of 7 to 3. There is also included in the pamphlet a description of a motor-driven rotary drill which has been devised, owing to the difficulty of obtaining fuel and boiler water for the ordinary steam-driven rotary drill.
