THE NEW ZEALAND GOLD EXTRACTION COMPANY. PROSPECTS OF THE NEWBERYVAUTIN PROCESS. THE MANAGER, TO ARRIVE NEXT WEEK. Auckland, July 6.

Yesterday Mr D. G. MacDonnell, locaj Secretary for the New Zealand Gold Extraction Company, the association possessing the patent rights for this colony for the Newbery-Vaubin process of gold extraction* received a letter from Dr. Scheidel, intimating i hat he was to leave Sydney by the Robomahana for Auckland, and that he will consequently arrive here on Tuesday next. Dr. Scheidel ib the expert sent out by the London patentees to erect and superintend the works here. Immediately on arrival he will proceed to the Thames and will supervise the erection of the machinery which has arrived during the past fortnight per Aorangi from London. The Thames plant when completed will be equal to the treatment of 200 tons of tailings per week. It will commence operations on the immense deposit ot tailings on the Thames foreshore — the accumulation of 20 years — amount ing 1 to many hundreds of thousands of tons. The average of the tests made of the bailings so far is about 6dwt per ton, though some parcels have given much richer results. Before treatment by this piocess the tailings are concentrated from one-sixoh to one-eighth of their rough bulk, the cost of concentration being merely nominal. The total cost of tieatment is estimated at 14s per ton of concentrated tailings. At the present time, when the process is about to commence active operations, a few words about the Company will be of interest. Its headquarters are at London, Air F. Thorne being chairman. The Company has a capital ot £100,000 of £1 each. The local directors are Messrs L. D. Nathan, R. Rose and R. Spratb, and these gentlemen, we understand, are the only shareholders in the colony. Of tourse, so many new methods of extracting gold from pyrites and tailings have been brought before the public from time to time, and so many of them pronounced to be certain of success, have proved rank failures, that the mining public in this colony has ceased to place any faith in promises unless backed up by performances. But the same feeling of doubt can hardly apply to the Newbery-Vautin process, inasmuch as it does not represent a new system m an experimented stage, bub simply consists of the application of impioved principles which have the effect of saving time and expense while increasing efficiency to a system already proved to be valuable — that of chlorination. For many years the chloiination process has oeen in use at the Thames and elsewhere, and the results which have attended the use of the new process at Mount Moigan, Queensland, Sandhurst, Victoria, and other well known goldfields speak for themselves as to its efficacy as a cheap, efficient gold saver, while its practical application to the refractory ores at Norton, Queens'and, containing copper, zinc, lead, sulphur, and arsenic, encourages, the beli«f that it will prove serviceable in treating the wonderful complex ores at Karangahake and Te Aroha.
