Bisbee daily review., 1918-03-24

In the Globe-Miami district. Arizona Commercial, Iron Cap and Old Domnr ion development work on their lower levels is steadily broadening the eA- pectations of a great deal of increase in higher grade resources at depth Ill the district. Much increase has been made to proven ore areas in the last several months. Among developing properties yet to establish themselves as made mines, Porphyry Copper, New Dominion and Van Dyke are most talk ed about Porphyry Copper continues to send excellent ore from its develop men work and is considered practically a poven property. Work being prose cuted on the 600 level in establishing continuance of the ore bodies above is fast determining the commercial standing of the property, while the drift going out to the Live Oak line of Inspiration is opening to view ad- ditional high possibilities. The con trol of POrphyry is in the hands of the Coplen interests, whose original faith in Inspiration and persistence Tn its development is entitled to re- sponsibility for the ultimate steps which made that great producer. Por- phyry ground is next to the Live Oak property of Inspiration and has been contneded for by Mir. COplen as better piece of mining country than the Live Oak, on which Inspiration has it's deepest workings and at thls depth it's richest ore.
 Realize War Need of Metal
 In the mechanical division of min ing in the state, Calumet & AriZOna-s new electric pumps, which are sending water from the 1900 level of Junction shaft to the surface, are centering a great deal of interest among technicaI men, Electric pumps have not before been put under such strain and some slight alterations have been necessary in meeting the requirements, but only such as attend the installation of most machinery on new work. The try out has practically established that the pumps will prove a very decided success. In that event they will work considerable economies in handling the water of the district. In the Copper Queen smelter at Douglas the attention of technical men has been claimed several times in recent months by betterments in .cOnstruc- tion and practice which have had much value for the industry. A late gain has been in furnace arch coh- strgction, which materially increases output while reducing fuel consump- tion. At Ray and Miami there are continued efforts directed to better ments in practice At Humboldt the plant of the Consolidated Arizona smelter. as it has been remodeled and as it is being increased, is proving in practice to be a remarkably ad- vansed and efficient piece of work. Much attention is being accorded il by shelter experts. At Clarkdale tho construction of United Verde Exten- sion smelter is advancing eXcellently. while at the United Verde shelter the betterments which have been steadily in progress with increase in capacity of plant are giving high results. Tech nical men in mines, mills and smel ters of Arziona never before extended themselves as they have in assOc-a' tion with the homogeneous of thelr companies since the declaration of war. No point is too small to arrest their attention and get overtime CT forts on their part if it holds forth the slightest promise of enabling in crease in output of plant. These men have broader realization than those of any other divisions in mining or the great need in which the fighting forces of the nation and its allies stnad of na abundant and unfailing supply of copper metal
 Leasing Proving Real Aid
 Soon after the declaration of war
 
 of copper producing properties who had withheld from the system in many instances concluding that the circumstances of the nation justified them in making surrender of beheIs they held as to disadvantages for them in connection with leasing. In conse- quence of the change in attitude ben efits are now beginning to show in reports of some instances in rich ore from custom shippers and in the open inf considerable new ore resources. Were the price of the metal higher, there is no doubt but that shipments of custom ere would make marke- gain from the leasing sources, as Wen as from other small operacOTs wle are at the present price confined 10 their highest grade ores. Also there would be attendant gain in the amount of development conducted by leasers and the increase in ore resources of the state Notable among leases max ing gccd under development are the Boreas and the Nighihawk in the War ren district The Boreas at 100 feet has recently come into ore that prom ises excellently for the making of a considerable body The Nighthawk has been in good ore for some time and is Of much promise. Both these properties are doing no small bit in the matter Of showing the way to i'm pOrtant expansion Of the proven area of the Warren district Tn hal- dozen other instances the same mag ner of important gain is beng mace for them throUz h leasing ODerae-oHs.
 Copper Metal Situation
 NCw York reports continue 10 tel Of shortage Of metal output from the refneries and of delayed deliveries OI bullion from the mines. Bullion sh-p- ments are scattered all the way from the shelter yards 10 the doors or tae refneries. However. best opinion is that even were tie bullion getting through without delay, and even were it all in the refinery yar-s now. tlere ..-~.-.rr ..o+ l,a ancsrvh rourar in ufohf
