Show 0 THE GOLCONDA MINE AND MILL special correspondence kingman ariz the first section of the golconda mill with a capacity of forty tons per day has been completed and trial runs made recently have proved highly satisfactory the plant is a standard concentrating mill with crushers rolls jigs and wilfley tables some idea can be gained of the richness of the milling ore on the dumps from the fact that the poorest milled so far has concentrated about three into one manager john boyle estimates the total of his milling ore already broken in the and on the dumps at about tons worth about 8 per ton the cost of milling should not exceed 2 per ton so that the dumps will probably net about of the above tonnage tons will average 35 per cent in zinc and will concentrate into 1 work has been started on the second section of the mill and eighty tons per day will be handled by the first of november in the meantime shipping is continuing steadily at the rate of tons of 48 per cent zinc ore per month up to the present time the golconda has shipped tons of ore nai netting eting about above freight and smelter charges As yet there has been no done below the fourth level which is only feet deep and the amount of ore in sight insures a steady production for many years the prosperity tunnel which will largely eliminate hoisting in the golconda is now 1000 feet long and has been in good ore for some time the face is still SUU SOU leet feet from the known big ore bodies of the golconda but from the present showing a new shoot of shipping ore is expected soon in the tub mine owned by boyle personally so development work has been stopped for the present with a forty foot width of fine milling ore thousands of tons of which are already blocked out boyle has stopped further work pending the erection of a large mill for the treatment of the tub ore alone although the tub and golconda are adjoining mines their ores are quite different in character golconda ore is a simple combination of lead and zinc sul aphides which are easily separated by jigs the tub ore is rich in copper pyrites f from rom which zinc can be extracted only by magnetic separators the copper pyrites however carries better silver and gold values than the golconda ore so that in the end it is just as valuable the gold road mine drifting east from shaft no z on the foot level of the gold road mine has disclosed still another ore shoot with about seven feet of good milling ore the latest strike is the beginning of the third shoot of ore in the mine the first being 0 1100 feet long the second 1200 feet long and each averaging twelve feet in width there are still about feet of virgin ground with excellent droppings crop pings the 40 stamp mill is handling about five and one half tons per stamp which will be helped by chilean mills now being installed the tom reed mine paid its second dividend of three cents per share several days day ago the ten stamps are crushing about forty five tons per day averaging a little over 40 per ton the stamps of the old mill are to be moved up to the new and will be put into operation as soon as pos sible at the ruth mine the new shaft at a depth of thirty feet is in better ore than that found in the old at a similar depth since cyanide tests made by dan bosqui mill superintendent of the gold road proved an extraction of only 58 per cent all idea of an extraction by percolation alone has been abandoned and thorough mill tests of the ruth ore are now being made by the young construction company of los angeles A plant similar to that of the gold road will probably be erected J levescy Li operating in leadville and old mexico is in the district examining properties in the interests of leadville capi tal J H ROSENBURG |
