Show OPENS ilEWPROPERT! The Calumet & Arizona Mining company, com-pany, which has within the past five years opened in the desert of southwestern Arizona Ari-zona the wonderful New Cornelia mine, is now engaged in developing a new subsidiary, sub-sidiary, the Gadsden, a promising prospect pros-pect adjoining the United Verde Extension Exten-sion property in the Jerome district, according ac-cording to the Boston News Bureau. In 1914 the stock of the United Verde Extension company sold on the Boston curb at 32 cents. On Thursday last week the same shares were quoted at ?f2. The average yield of copper per ton of Verde Extension rock treated during 391S was liO per cent, or 400 pounds, a record not approached by that of any other copper mine in the vorlji The 760-odd acres comprising the Gadsden Gads-den group of claims extend southeastward from the United Verde Extension boundary bound-ary along the strike of the Great Fault. Near the northeastern Corner of the property prop-erty a 1200-foot shaft has been sunk and crosscuts have been driven in both directions direc-tions at right angles to th formation. The sou tli western exploration cut the Great Fault and openings in several directions di-rections have shown native copper and scattered sulphides, though not in commercial com-mercial quantities. Tho consensus of opinion among the many professional and amateur mining men who have visited the properly is that the chances of iind-ing iind-ing an ore body a few hundred feet below be-low the present workings are good. The main shaft, toward which the fault-plane dips at an angle of about u0 degrees, will be sunk 300 feet farther and a new crosscut cross-cut driven to explore the ground along the Great Fault. A crosscut eastward from the shaft at the twelfth level has just cut what appears ap-pears to be a parallel fault fissure,' the occurrence of which has ben expected by a number of geologists of experience in other districts. It is of interest to note that in the southeastern end of the Gadsden tract a , prospector's tunnel in the side of a gulch on the Howe clajms discloses a good surface sur-face showing of copper and silver. Near this point (difficult of access and seldom , visited by tender-feet), during 1906, Horace J. Stevens planned to sink a shaft to explore tho ground at depth, but the panic of 1907 put an end tp the project. The Gadsdjun company has lately ac-1 ac-1 quired three more claims carrying the lower extensions of the formation that outcrops above the Howe tunnel. It ia 'likely that further explorations will be , undertaken at this point- Gadsden is as , yet nothing more than a speculation, but : it has the best equipment of all the prospects pros-pects in the district and the advantage of being under the able management of i the Calumet & Arizona engineers who j produced New Cornelia. |
