MINING.

The Waihi Gold Mining Company, during the period ended October 20, crushed and treated 15,908 tons of ore for a return of bullion of an estimated value of £27,861. Compared with the return for the corresponding period of last year, when 15,229 tons yielded £26,076, this shows an increaso of £i 785. The value of bullion won from the mine to date is £11,780,751. The following cablegram has been forwarded to the London office of the company: —No. 11 level: The crosscut across the north section of the Empire lode, in the Pistol northwest crossout, has been continued a further 10ft, from 16ft to 26ft. This 10ft assays 22s per ton. It may bo stated with some degree of confidence (says an Australian exchange) that much more will bo heard in the near future than in the past of the Kincr Island Scheelito Company, in which the Broken Hill Proprietary Block 14 Company has a large interest. The first shipment of concentrates was made on September 24, amounting to 25 tons, valued at £4250. representing an right weeks' run of the mill. The Block 14 Company holds 42,000 out of a total of 100,000 shares. Tho first estimate of power derivable from the King River, Tasmania, for the production of electricity to supply metallurgical works on the Mount Road-Roppbery miriPS, was 30.000 horse-power. Mr Huntley Clarke, tho civil engineer and surveyor, who drew up the plans of the Lake Margaret scheme for the Mount Lycll M. and R. Company, and who had surveyed the King_ River region, told the Public Works Committee of tho Tasmanian Parliament that he was satisfied that 45.000 horse-power could be generated This, however, would involve building a concrete wall 180 ft high across the river, and tho water thus held up would form a lake of about eight square miles. There would be a head of nearly 500?t at the power station. During tHe month of October the Murray Creek Gold Mining Company (Ltd.) crushed 1460 tons of ore for an approximate gros« return of £3052.
