Bisbee daily review., 1907-10-27

ficial figures. It seems to be generally accepted that about g 1-2 cents a pound is the present average cost, but have nowhere seen the basis of that reckoning the factors--clearlt stated.
 The gold and silver (mostly the lat ter), however, are very high. amount ing to about ? 1-3 cents to the pound of refined copper iR the Montana ores. do not know how this large value is distributed in reckoning the cost of copper. The mining is deep, difficult and expensive, but the management is very able and there is plenty of working capital to introduce every aid to economy.
 Cost of Producing in Arizona.
 The great advantage that Arizona possesses over Michigan or Montana lies in the low cost of mining, arising from the fact that all its deposits lie relatively close to the surface. and that the ores are mostly very docile to treatment As the deposits worked up to the present have been mostly in the lime they are quite largely self fiuxing an item of great importance to cheap smelting. This is an advaa. tage that no other extensive copper district in the world possesses.
 Except in the Clifton district the milling of copper ores in Arizona is miles behind that of either Michigan or Montana, but the smelting is equal to the best.
 The general paucity of water has retarded the development of milling ores in Arizona in many places where they are rather abundant, while the quite unusual ease with which the smelling grades were obtainable, their unusual abundance and the relatively small capital required to convert them into cash, have all contributed to concentrate effort or the development of smelting grades to the neglect of milling ores. which energetically op- erated are able to swell the output greatly
 The cost of producing the copper in the two principal mines of Bisbee Cthe great Copper Queen and Calume; 6 Arizonal is as low, and probably slightly lower than in the Calumet & Hecla of Michigan It is publicly stated that the Calumet 6 Arizona of Bfsbee is now producing at a cost of f-2 cents a pound The statement is probably true but refers to only g brief period and is, therefore, mis' leading; but it is not. I believe. al official statement. It seems fairly safe, however, to state the cost of production of the only two fully de veloped and equipped mines Of Bisbee al close to T cents pound, At Globe and Clifton the cost is considerably higher, but pretty certainty within s 1-2 cents.
 At Senator Clark's great mine, the United Verde. iR the Jerome district, the cost is very low. if account be taken of the gold and silver; prob, ably not in excess of 5 cents a pound. It seems fairly safe to state the ave rage cost of producing for all Arizona at [ 1-2 cents a pound and 10 other NOEBGA 4GS4Oh III NALt "O- tA Ao iDlG u produce an equal quantity of copper at as low cost as that, nor within a cent a pound Of that cost.
 There is the whole secret for you Of Arizona's assured pre-eminence a2 Q producer of copper.
 Gan She Hold Her Psee71 1 Yes, Arizona can certainly hold her rate of increase for long time tc come and if ample capital can be ea listed she can greatly increase heI pace almost immediately. It is true she has so far been skimming the cream of her great mines, but there is a great deal of such cream in Ari zona yet to be skinned, and all the older mines are holding out well al depth.
