Bisbee daily review., 1920-04-18

! ne DuldGG-AI IlzOna laS been doing little work for several months, suspen- sion being due to an thrush of surface waters from a shattered vein. The water level now stands at 600 feet but as the rainy season is thought to be at an end pumping is to be resumed.
 The S30-foot shaft is to be extended To $50 feet and q drift ran nOIthward to contact wherein there is cOnf.- dence that an ore body will be devel- oped. Shipping from the , per cent carbonate surface capping has been suspended, awaiting higher copper val ueS and the developments of volati- 2ation process for the treatment or such ores at the Humboldt shelter.
 Jerome Superior has a new 625-foot compressor. added to older equipment of compressOTs of about 1000-foot ca paCity. A siXinch water column has been added to the five-inch main al- ready in the shaft and a new pump on the 700 level. The main shaft is being dcepened from 750 feet and two d;a- mond drills are operating on the TOO level.
 Verde inspiration nas installed a stamp mill for it's gold ores and re- ports the development of much good copper ore. E. H. Meek of Prescott is m charge.
 From Miami comes confirmation of the sale of the Porphyry property to it's great neighbor, the Inspiration, which lately added the Warrior prop eIty to iIs holdings and which is said to he looking for still more acreage in this district, in which it now is the largest landholder starting 10 sva,o ago with only'12 claims. to which have been added the Live Oak, Keystone, COrdOva, Eureka and Warrior groups.
 The PoTphyry has stopped drilling and it's officers now are in Kansas City attending to details of the transfer Tho drilling is said to have developed q considerable tonnage of good milling sulphide. Inspiration has closed it's experimental teaching plant, in which
 is understood to have been deterlnin- cd a process through which profit can be secured from millions of tons of low grade oxide and carbonate capping ores that have been passed over in the company's operations thus far and which have served only to lower the percentage of extraction in the 20,000- ton mill in which the sulphides are handled.
 Miami Copper is doing much 10 make it's new No shaft a model one. The crushing plant will be of concrete, 90 143 feet and there will be e mod ern change house. 62 116 feet. Bids nave been called for for these and for
 Q sampling plant, all to be completed within 100 days.
 Superior & Boston has opened up the stopes closed by the mine fire of last July and has found the fire gone and the air good The workings are badly caved and much repair work will nave to be done, as the timberS Of the section are gone. Drifting is being pushed on the 600, to get unGer the rich ore found 200 feet above, and the same vein is being approached on the 500 level
 In Yavapai county there are a great many of the old-time gold-silver-lead mines that were worked successfully 20 to 40 years ago when silver was high and aS long as the old amalgama- ton process would handle the ore sue cessfuily. As depth was attained in the properties the ore became more re- fracJory and no process was at that time known that would successfully handle the sulphide ores of the milling grade.
 Big Copper Bearing Belt The mineralization area of the county ty is larger than two or three of the eastern states put together. | The copper bearing belt begins at Je' rome on the north, where are located !, the two great Verde copper mines, and | extends in a direct line Southward oV- i I A rt now opened up all along this great mineraIized belt. The formation is | known as the "Yayapai i 5chist" At the south end of this great ] vein system is the Kay copper mine. | financed by local people and large in | -erests in Detroit and New York. A | body of copper bearing ore 500 feet in ! width has been crosscut on the 60O-foot | eyel, consisting of lenses of high grade smelling and lower grade mill 1 ng ore.
 Many Excellent Prospects |
 The gold-Silver-lead districts parallel ! his copper belt on the west and cover m area at least so miles long and 50 niles wide. There are literally hun lreds of excellent prospects for fuI- !, her development in both the copper J
  If the camps have rich gold veins Of gold and silver. The silver-lead prop ,sitions are ideal for the poor man < for not much capital is no- 'essary to make them into producers since the ore is, for the most part, ound at the surface.
 The development and the use of the ,il Notation process is really the N"y hat opens these old properties 10 fur her successful operation. Mills of this sind are springing up all over the They cost less to install than other mills of the old processes, are operated more Cheaply and they save all of the values, even in ne complex ores of copper, gold, sil- Ter. lead and zinc.
 Tail Goes With Hide"
 Stockholders of the shannon Copper once of Clifton, have agreed to let the tail go with the hide" , from the sale of their mines at Met 'alf, their railroad and their smeltinS ,lant below Clifton, they have paid
