Arizona silver belt., 1901-05-09

init of profitable treatment in Arizona of average grade silver ore, but al- though the white metal has decreased in value there is reason to believe that under improved methods the mine may be profitably operated on a large scale.-Los Angeles Herald.
 The Mammoth. Collins company are installing at their Schultz mines, Pinai county, a mammoth air compressor to drive Ingersoll drills, which will be utilized in opening connection be- tween the Mammoth. Collins mines.
 The completion of this connection will enable the company to work the Col lins mine through the Mammoth double compartment shaft. The re. cent cave in the old workings of the
 Mammoth did not affect this shaft or any of the ground between it or the Collins mine. The immense ore re- serves in the Collins have hardly been touched yet and insure continuous operations at Mammoth. The ore is said to be higher grade than that of the Mammoth.-Citizen.
 "The copper mines at Clifton and
 Morenci will increase their output thirty per cent this year." said Mir. o. NJ. Shannon of Clifton, to Citizen reporter. "Clifton shows greater prog ress than any camp in Arizona. New buildings, Improvements in the streets, and a general movement toward en- larging and modernizing the place has set in" Mir. Shannon says that the smelter of the shannon Copper com pany will be ready within six months to begin the production of copper bullion. A number of other mines in the Clifton district are to be equipped with smelters, and the eastern DOT tion of Arizona will contribute its share towards the great increase in copper production which Arizona will show this year.
 The successful development of a mining property and it's establishment as producing and paying propo- sition, as general thing, is an under taking requiring the investment of considerable capital in systematic work before any returns can be looked for. The equipment of mine with hoisting machinery and the incidental appurtenances thereto, together with the employment of labor, are items of expense that rapidly merge into large sums-sums beyond the means of the average prospector-and must be fully provided for before the undertaking is commenced if the parties to the ven ture would avoid financial disaster With arrangements made for such necessary investments the mining in duslry holds out as promising induce ments as can be found anywhere in the field of industrial enterprise.

 Several carloads of machinery and lumber have gone out to Gila City within the last few day 8, to be used in the inauguration of an enterprise which has for its object the securing of the gold which abounds in the gravel of that section, or so much thereof as happens to be in the ground owned by those interested in the de- velopments proposed. The intention of the gentlemen, who are l.. II. Jones and E. c. Potter of Los Angeles, is to work their ground by the hydraulick- ing process, and to that end pumping machinery has been placed on the ground for the purpose of conveying water from the Gila river, close to which the claims of Messrs. Jones and Potter lie. They have two twenty acre claims from which most gratify- ing results have been obtained, &C., cording to long series of tests con. ducted by Mir. Potter recently. Ac- cording to these tests the gravel which carries values is about eight feet in and averages almost s2 to the
