cnPPER MINING.

Tas ooDper boom in Arizona IS bring -.--, r-omluence many hitherto neg ,-'.,s mines which are intrinsically val
 -bre and as encouragement to the ,--.1orment of such properties the D..vs- Mining Review gives the fol- [.-,,, advice. IL says: "Oi the extent

There are .,rsrer. many peculiarities connected -r.b the search for copper which lead --,-..,rt1-s into erroneous conclusions .-....-,iDr the quality of the ore they .e.- find. One Of these, very common .- fact. is that a comparatively small ..-,e,tace of copper will exert a pow --srr influence in the discoloration of --,s To such an extent Is this known m many places that where, to the inex- -s-isrcsi eve. a highly eupiferous -.- nav be looked for, exami- ..--r and test will prove 1t to be .-. reverse. We frequently hear .f ,oDpsr mInes that will average ..,vbe-e from thirty to forty and zs-v ra- cent. ot that metal, but We have -, knowledge of such a mine being r5-ked on a large scale. They are very -,r,b Ike the thousand dollar gold and s,rrs- mines: We hear of them only when they are discovered and the first reports fl tlei- exceeding richness IS being .r.-sgi over the country. Nothing eI- .i+-s listrust nowadays among mining men more than reports of unusually -,b finds. especially where the parties circulating them are interested. What .s wanted in copper Is large bodies of tir grade ore-ten to fifteen per cent ril do. or less if il is free milling-snd mi uncertain or small quantities of forty a-fftv per cent. ore. One of the largest ,a1per reducing establishments in the e5gDtrv IS situated in the city of Balti- ,o-e. Maryland, and m the course of s5rvsrsation the principal proprietor when asked about the high grade ore shipped to him replied that all the thirty. forty and fifty per cent. copper ores came to his establishment in cigar boxes. but that the carload lots, upon which he depended to keep his works in r1srati0u. averaged far below those figures. Again, the copper bonanZas of A-zora, which now lead in the western --1iuction of that metal, and among z.icl are the Copper Queen and Cop Der King mines do not average any such remarkable figures as many seem Co imagine We are reliably informed that the treated ore of the Queen IS seldom allowed to run below twenty Der cent. as that proportion IS -e,essary to produce the amount of --dat demanded by those controlling 1t. lu order to maintain this standard, fully -To-thiri- ui the mines product IS lsid .sle a- uor being of the required value, and Co awu- the time when cheaper transportation and better facilities will make 2, advisable to handle it. Ma ---lIy tLese mines produce quantities of --L metallic stuE, but the Calumet and Hec.a does the same thing and get its average ore will run from four to SIX per cent. only, but being adapted for treatment by the milling process and existing in immense quantities, the la--u or profit .s large. The ores Of :l- southwestern portion of New Mexico, many specimens of which are gl exhibition now in Denver, certainly give abundant promise Of copper fields worthy ot investigation, but the miner vlo, because he finds rich croppings, thinks that bis ore will average any s1cl exceptional figures, will find his mistake when ready to send his product to market. A proper encouragement extended to the copper districts of New Mexico will, We are sure, result in the development of mines capable of com pLrng favorably with many of the frQunent ones elsewhere. As It IS tley are already being developed by an energetic and practical class of men and that they will come splendidly to the fore when once understood there IS no reason Co doubt"
