The treatment plant at all the company's mines is somewhat similar, the order of treatment being from stone-breaker to screen, jig, Wilfley table ; tailing being finally crushed by stamp battery. The concentrate now obtained never contains less than 70 per cent, tungstic acid, which may be regarded as high concentration. The gold is no longer saved at the Glenorchy mines, owing to the low tenor of the quartz in this metal. In the annual report of Inspector Whitley, in the Annexure A accompanying this report, reference is made to the foregoing mines in addition to the scheelite-mining operations at Macrae's, Stoneburn, The Reefs, and Waipori; and in the report by Inspector Bishop reference is made to the gold-schcelitc mines at Wakamarina, Marlborough, where the output from the principal mine—the Dominion Consolidated—has declined from 110 tons of scheelite-ore, value £14,133, during 1915, to 67 tons, value £11,849, during 1916. At this mine development has not been satisfactory, the lode having pinched out above the bottom crosscut, and prospecting operations underground for its recovery have not been successful: The company, however, has considerable reserves of low-grade scheelitequartz in their Golden Bar Mine, the value of which may be too low for it to be worked, profitably.
