Waiorongomai.

Hardy, Edwin Henry, Mining Engineer, Mine and Battery Proprietor, Waiorongomai. Mr. Hardy was for sixteen years in the New Zealand Civil Service as Government Surveyor in the provinces of Otago and Auckland. He was educated at the Dunedin High School and Otago University, and in England. Mr. Hardy recently purchased the mines, water races, and battery of the Aroha Gold Mines, Ltd., an English Company operating at Waiorongomai. This company spent £15,000 upon the ground, but retired, having failed to discover a payable lode in its lower levels. Mr. Hardy, after a careful examination, ascertained that these had not driven upon the gold-bearing reef exposed in the surface workings, but about 30 feet off, parallel thereto. A few months' work laid bare a fine reef, which, auring eighteen months, has gone from 3 feet to 9 feet in width, kept a ten stamper battery going day and night, and produced nearly £6000 worth of gold. The battery was originally arranged for dry crushing and cyaniding, but is now well equipped with the most modern wet crushing appliances; electroplates, grinding and amalgamating pans, concentrating vanners and berdans, in addition to a complete cyanide plant. To meet the increasing supply of quartz, an additional ten stampers and other appliances are now (1901) in course of erection. The motive power is furnished by four Pelton wheels, from 2 feet to 6 feet in diameter. Mr. Hardy is also attorney for the Waitaia Gold Mines, Ltd., Glasgow, and the Hampton Plains Exploration Co., Ltd., London.
