Bisbee daily review., 1912-01-07

ages full B Der cent copper and num- erous assays give the gold and silver contents per ton al S476. which is about the best precious-metal value ever found Tn the Bisbee camp. The importance of these two discoveries IS in proving that this great stretch of ground is copper-holding and that the ores are very high grade. Nor are these recent finds in direct line. one with the others with the strike of the formation in that portion of the camp, several hundred feet dividing them if a line were drawn straight through the country and based on tho formations strike. So that a. any place between these points ore may be expected, and also for sever al hundred feet still beyond the side lines, as marked bx these recent de- velopments.
 Cole Looks Fine.
 To the west Of this Rathburn claim where the new rich find is being opened into. the Cole lies at a dis tance of nearly 5000 feet, and here recent developments have shown large bodies of high-grade ore. This point is more in line with the Mag and Oliver shafts Of Calumet & Ari- 2ona and of the Lowell shaft Of the Copper Queen company. So one, look ing at the map. with recent ana older developments to guide him, can see wonderful wide sheet of ore-bear- ing formation making downward through this valley to the southwark its broad bosom bearing millions up on millions of tons of pure ores run hing high in copper and gold, and with the work as yet not fairly be- gum.
 That's the Reason.
 lt was the knowledge of these facts that gave Mir. Greenway everything he wanted in the way of a new smelt- CT. because it is apparen. 10 the board of directors that the conditions well warrant the outlay
 Here Are . Few More.
 There has been lot of talk con. cerning the probable depth of the pay ing ore deposits in the Bisbee basin. The Oliver shaft of the original Cal umet & Arizona holdings is pretty well up at the north side of the bas. in SO far as the latter has been proved. The Oliver was put down until it was 1.450 feet below surface when a drift was started from an ad- Joining shaft 10 cut ground 250 feet still lower. or al 1,700 feet below sur face. It is interesting 10 learn that this drift found good body of ' per cent ore, being the regular enrich ment found at points higher in the shaft It was a most satisfactory showing at this particular location. And Still Another.
 The NOGf of 9EiUp pp1fUl Of com per by Calumet & Arizona has been steadily coming down. The work hes been centralized until now only three shafts are used for hoisting Where there used to be a dozen dinkey en- zines operated there is now only | one Things have changed as de yelopment has progressed and size and shape and character of the | ore bodies determined. More is learned about the ground. Where | raises used to be carried two sets
 wide and heavily timbered, now only one set is observed. Under the old | system two full sets were carried l along even in exploring raises. And of course the ground surround | ing the Junction and Briggs chafts | is now much more dry than before l as the constant pumping has lowered
 the level and gradually dried up the | water flow. Ground is much more l easily handled than when it was so wet, naturally. And the performance
 Der man per day has been improved | by these natural changes and by l alterations in former practices made | possible, due to various causes. A Question of Cost
 And cost is the main thing con
 sidered in these days. It must be
 the everlasting object of attack Iron | Ore knows that Calumet and Arizona | has 8 most satisfactory cost sheet these days, it being very much bet | ter than some writers have been es | timaung. And, with the new smelt | CT in operation, the cost will come 1 down another notch. 1t is certain
 the company will not be forced out Of activity due to any competition l from anywhere.
 A Conservative Course
 In talking with several prominent directors of this company we | learned that there was going to be | no wasteful crowding of the busi 1 ness, but that the property would be handled for the very best interests oi | every shareholder, and for their chil | dren and their children's children | That sounded as if the faith in tho future of this organization had not l diminished.
 l Has Ground to Explore lt will take more than fifty years
 to thoroughly explore the lands oi l this company, to say nothing of ex | hausting it. How deep the ore vii l go Is yet 10 be proved. Some idea | Of it's lateral extent is had, but the | Oliver has commercial ore at 1,7OC | feet. and the bottom of the Junction | 100 feet lower, has very rich ore
 and no one knows how far that vii 1 continue downward. Some of these
 ores make very close to the surface
 At one place near the Cole shaft | they outcrop.
 At the Hoatson Shaft At this opening on the Del Nortt | claim. there has recently been aI
 addition to former known ore bodies
