 It is of much value in further demon strating the persistency of the ore bod ies in this portion of the Bisbee camp and makes the bonanza circle larger than heretofore in it's known radius. It furthur emphasizes the wisdom shown in the original purchase of the Junction lands as well as the claims subsequent ly gathered in by the company in the immediate vicinity of the Junction group. All these acres are going to be heard from in the future, and this was the idea of those who suggested their taking over.
 The Calumet and Arizona has leased the upper portions of the Irish Mag shaft to local miners, as previously an- nounced in The Review. This takes in all that portion of the shaft on the Irish Mag claim above the 100O-foot level. There is chance for deposits in this upper country, and it is not inn probable that good values in gold, sil- yer and lead may be shown in ground above where any mining has thus far been done. Gold and silver associated with lead are important products in the upper portion of the Gardiner mine and also in the Southwest and Uncle Sam divisions of the Copper Queen company, properties occupying the same geological level as Irish Mag ard located close by.
 The hoisting plant at the Mag shaft is being repaired so that it may be used by the miners who have the lease and as quickly as this is in commission work underground will be started. Thos. Stafford, an old miner, and Richard Whiteside, well known in that region, are among the principals in the deal
 Since the experiments were started by the Calumet and Arizona Mining company and the Copper Queen Mining company in the electrolytic treatment of ores of the Arizona field, great general interest has been aroused in this work. The Copper Queen, in it's experimental mill at Douglas, demon strated it's ability to make copper by this process, but did not carry the work through to final point. It will do this in the near future, probably. It has expended about 100, OO0$ at it's Douglas plant. The Calumet and Arizona com pany conducted experiments along the same lines, but with different process, in its Douglas test plant, since which time it transferred it's operations to Ajo, at it's New Cornela mine location, the ores from which are to be handled by this process. A 40-ton mill is soon to be ready here, and will be operated on what is known as the Greenway process. There will soon be some high ly interesting figures on the results ob- tained at Ajo by this company, and we predict that they will surprise many people in the percentage of efficiency shown in the tests. The producing of refined copper right at the mines is the ideal operation and that is what is to result at the New Cornelia plant when it is finally ready for business. It will not be many years before copper here tofore considered of no value conner cially by reason of their being low in copper contents, will be handled at a profit, which will be conservation in the right way. The day is coming when conservation of copper will be much talked about because there will be need of all this metal that can be produced. Copper is going to be demanded in greater quantity than ever before. - Bisbee Review.
