GOLDEN DAWN PROPERTY. REVIEW OF OPERATIONS. RETURN FROM BULK CRUSHING.. Tho first P' -'ual meeting of shareholders in the Golden Dawn Gold Mines, Limited, was held in Auckland recently. The property is situated at Owaroa, Ohinemuri. Mr. John Farrell, chairman of directors, presided, and in moving tho adoption of tho directors' report and statement of accounts, referred to tho operations carried on since the company hart been formed. All assays taken of tho reefs in the mine had been satisfactory, but it was felt that treatment of a bulk parcel would bo tho most convincing proof. Consequently, 504 short tons (equal to 450 ordinary tons) had been treated at the Waikino Battery, by permission of the Waihi Gold Mining Company, and was valued on continuous assay at £3 17s per ordinary ton, 90 per cent, of the value, amounting to £1546 15s Sd, being paid to the Golden Dawn, Limited, Company, less cost of treatment and incidentals. None of tho richer faces was included, as tho test was of the general run of ore. . These richer faces would be available to build up tho return to a higher average level when operations wero in full swing. Tho mino manager, Mr. R. It. Morrison, formerly manager of the Blackwater Mines, Reefton, had expressed his opinion that tho Golden Dawn had better prospects than that mine, the reefs being larger, and tho average vajues much higher. Tho directors had been j;dvised that the full equipment should include a complete filtration plant and attendant appliances which would increase the extraction to something well over 90 per cent. This would bo an extra cost, but, when completed, the plant would be as completely equipped for saving bullion as any in New Zealand. There were five working faces, all on payable ore, so that when the treatment plant was completed the production of a largo quantity of ore would bo facilitated. The reports and accounts wero adopted unanimously and Messrs. J. Farrell and D. B. Patterson, the retiring directors, were re-electcd. TALISMAN DUBBO MINES. PROGRESS OF DEVELOPMENT. The first annual meeting o): shareholders of Talisman Dub bo Gold Mines, Limited, was bold in Auckland recently. The annual report, which was adopted, stated . that driving on the Talisman Dubbo level was commenced on February 15, 1930, and up to December 15, 1920, the face of tho level had been advanced on the reef to 552 ft. from the tunnel mouth. Tho reef carried values practically the whole way, but three distinct runs of rich ore of approximately 70ft., 73::t. and 100 ft. in lengtli respectively were met, with, with indications that the runs were making wider under foot. Tho reef itself was a strong body of ore, varying from 2ft. to 7ft. 6in. in width, and' was typical of tho lode whero worked Talisman Consolidated Mine adjoining, from which that successful mino derived its returns. v A parcel of two tons of oro from the first run of gold was got out and sent to tho Thames School of Mines for treatment in order to test tho value of the reef, and proved to bo worth £9 ."lis 7d a ton. Future development work proposed is tho opening up of No. 1 Talisman level, which is 100 ft. below present workings, its continuation on the reef, and a rise through to connect with tho present level. It was estimated that a further £IOOO, with Government subsidies on driving and rising, would provide ample for the contemplated work, including aerial and hoppers, so that, assuming completion of negotiations for treatment of ore, the mine should in the near future become a producing property. The retiring drectors, Messrs. W. F. McCallum and R. H. Montgomery, wero re-clected. BLACKWATER GOLD MINE. Tho secretary of tho Auckland Stock Exchango received tho following advice from tho Blackwater Mine yesterday:— 4157 tons yielded 15970z. of fine gold valued at £6782. Working expenses were £5506. In addition, the furnace treated 93 tons of concentrates for 116oz. of fine gold valued at £492; working expenses wero £127. Profit over all was £909. OPERATIONS IN SOUTH. Golden Point and Scheelite. —-Two of tho directors and tho secretary recently visited tho property of the company. They report that tho wliolo of the battery plant is now on tho sito and is being erected. Tho battery will probably bo crushing by August 1. Development work underground is proceeding at. a satisfactory rate. Amplo reserves of oro are reported to bo in readiness for crushing. The . reef in tho new rise is at present oft. wide, showing on the Dominion analyst's assay an average gold value of loz. 9dwt. to tho ton, apart from tho scheelito content of tho ore.
