Calumet 6 Arizona Copper Co.


 The underground developments at Calumet X Arizona which have been in progress for some time, are not only among the most important which have taken place at the property, but certain of the ore bodies now being opened give indication of being the biggest thus far encountered in the Bisbee camp. These ore bodies are located in the Junction and Briggs sections of the Superior &1 Pittsburg property. Very promising developments have also taken place in the Calumet X Arizona ground in the Oliver territory At the
 Superior X Pittsburg the big ore body i in the Junction has now been deVel- Oped on three levels from the thirteenth ! to fifteenth. In fact it has been opened 50 feet above the 1900 foot level. mak ing a continuous ore body $50 feet high Work has proved this shoot for 400 feet in length on each of these levels while on the 1900 it has been opened for 500 feet. Its width is around 90 feet with the entire body averaging 7 per cent copper It will be seen from the dimensions and grade that there is very large tonnage and net value contained in this block of ground. \
 most important feature of the develop l
 on the 1900 or lowest level. and that the possibilities for it's extension with depth are very good In the Briggs
 there is located what appears to be one of the largest bodies of sulphde ore yet developed in the Bisbee camp. This body is very similar to that of the Junction. It has been opened on the 1 1900 and extends to 40 feet above the l level. It's width is in the neiShbOrhOod of 45 feet and it's grade is approximate i ly the same as that of the Junction ore ! bodies. that Is, per cent copper per l ton. At the Oliver shaft the ore body which was encountered last summer. ] which consists of q series of small i lenses of suIphide ore averaging 6 and i : per cent, is developing very well, and l has now been proven on two levels. i Tn going up on this ore body the shoots i are showing larger than on the sill l floor, and altogether the work is very ] favorable This was the most import ant discovery at the C. & A. in 1912. i Tn addition to the above developments some new ore has been encountered 1 along the Hard Scrobble claim on the | Copper Queen, which adds prospective value to this section of the Calumet x l Arizona property The developments i in the Superior & Pittsburg ground are i the furtherest eastward of any in the
 camp. In fact, each year new ore is 1 being opened in this direction. The | Calumet X Arizona company has a ! very large unprospected territory in this section of Bisbee which has very ! good possibilities The physical con l ditiOn of the Calumet & Arizona prop l critics is looked upon as highly satis- ] l bodies now under development have added considerably to the valuation i of the mines
 Bisbee properties WHERE'S THE 1 REST OF TT?
 Calumet and Arizona develop
 ment which is attracting considerable attention is the cOmpanys big steam shovel proposition in the Ajo Noun tains of Arizona. Advices are that l eighty-five drill holes have shown a good grade of commercial ore. and 1 that the management is now certain of having developed a big disseminat- ed ore-body, which. having no over burden to speak of, will be minable by steam shovel and will greatly augment copper production by the Calumet and Arizona Co. The man agement is not prepared as yet to give out any figures as to tonnage or grade. but people who have visit ed the property, say that the grade will run between 11a per cent and ? per cent. copper, and that develop ment to date indicates a tonnage running well into the millions. The ore is not amenable, however, to or dinary concentration, and the Calu i
 met and Arizona people have been eX perimenting with a teaching process which they believe will enable them
 to handle the ores at very attractive
 cost In the meantime, the company's
 new big smelter. which cost about
 $2 100000 is two months ahead of
 schedule on construction and the |
 first furnaces have been blown in. l
 This should admit of a very sub l stantial reduction in operating costs
 and permit of the economical treat l
