The value of bullion obtained from our quartz-mines during 1913 amounted to £1,071,813, as a result of treating 464,508 imperial tons of ore, in addition to which scheelite concentrates, value £22,933, was also obtained from, such ore. The dividends distributed by gold-quartz mining companies amounted to £287,088. The above-recorded output shows an increase when compared with that for 1912. The following is a statement of the quantity of quartz treated, the value of bullion obtained, and the amount of dividends paid by the most important quartzmines during 1913 : —

ALLUVIAL AND DREDGE MINING. Gold to the approximate value of £295,704 was obtained at sluicing claims during the year. This result is greater than the production by this class of mining for several preceding years. Alluvial-gold mining appears to have arrived at a more permanent condition, owing to the installation by companies of sluicing and elevating plants capable of profitably handling large quantities of low-grade wash. Although no development of importance occurred during 1913, with the addition of new mines now being laid down the future prospects appear to be favourable to the maintenance of the present output.
