Show I MANHATTAN DOING SATISFACTORY WORK 1 1 W. A. Berry of the Tonopah Bonanza force returned home from 'Manhattan Monday where he had been looking after eome mining interests, and when asked about the mining conditions In the Clamp j had the following to say: i Manhattan is making a record in Nevada for low cost of treatment of low-grade free milling gold ores. In the early history of tho camp the uniform milling charge for amalgamation, amalga-mation, fine grinding with tube mills was about 87.50. To realize a "profit "pro-fit it was necessary to handle ore of a value of from $20 to S25, to cover the cost of mining, hauling, milling, bullion tax, loss of value In milling, etc. Today, ore of a value of from $6 to ?7, and in one instance, in-stance, from 5 to $6, Is being mined, hauled, milled, etc., at a profit. This, of course, means the handling hand-ling of soft ores, where a large tonnage ton-nage may "be crowded through the mills, and by doing away with cyanide cyan-ide treatment, for It has been demonstrated dem-onstrated that the loss in the latter lat-ter mode of treatment Is so small, that it does not pay to cyanide the ores, Again, every advantage Is taken ta-ken In the mining of the ores to minimize min-imize the expense and Increaso the tonnage. On tho Riley Fraction, where the glory hole method of breaking down the ore is practiced, churn drills are used and with deep holes and large charges of "low" powder a hundred , tons of ore are broken down tvith one ' round of shots. , The ore at this mine Is a soft fihale and is sent direct to the mill as mined, and by crowding the stamps 1 and fine grinding by tube mill, is possible to mill 100 tons in twenty- four hours. However, In some instances where j . the value of the ore does not exceed ex-ceed ?o or ?6 a ton, it is necessary to crush and screen the ore beforo : sending It to the mill,. Old dumps, considered worthless a number of ; years ago, are now being screened j and liauled to the mills and are glv-; glv-; ing a handsome profit to the owners. So, on the whole it looks as though the future greatness of Manhattan ' rests on the successful treatment of ' its immense bodies of low-grade ores at a low cost. Capital is recognizing this fact, as I evidenced by the recent purchase of the old Mustang property, which has been lying dormant for a number of years, It being known that this prop-' prop-' erty contained large deposits of low-grade low-grade free milling ore. But It is possible that Manhattan-Ites Manhattan-Ites may some morning wake up to the realization that there are depos-, depos-, Its of high-grade as well as low-grade ) ores within the boundaries of the camp.
