Mohave County miner., 1917-05-12

ty, eight miles north of Stafford on the Arizona Eastern railroad, was acquir- ed by the Atlas Copper company. The copper area is an intrusive mass of granite porphyry, which can be properly classed as monzonite. This intrusion is through the diorite or country rock. The present develop ment has proven disseminated copper and the records from the drill holes give a tonnage of 96O,O0O tons of ore of an average of 3.65 per cent copper per ton. In addition to this tonnage of developed milling ore, there is a very large tonnage of surface ores, consisting of carbonates and oxides. The present development shows 2,5O0 feet of drilling, main shaft 325 feet deep and about 75O feet of drifting. The mine is well equipped with ade- quate machinery for development, con sisting of hoist, compressor, pumps, etc, and complete star drilling rig.
 For a number of years the Atlas Copper company's claims have been productive, and previous to 1917 there had been shipped or milled from these claims in the neighborhood of S4O0,- 900 worth of copper ore. A portion of the ore had been treated by crude concentration on the ground. During 1916 shipments or ore were regularly made and returns from nine cars shipped from June 1 of that year gave net shelter returns of $12,067.46, af- ter railroad freight, etc., had been paid. These cars averaged 45 tons of ore each, with a copper metal con tent of 712 per cwt., while on some of the cars 60c for gold and silver was approximately S52,OOO, the shipments consisted of carbonate ore from the surface. The total amount of the net returns for the balance of 1916 were approximately S52,OOO, the shipments being made to the smelters at Dou- glas and Ell Paso.
 At the present time large force of men is at work continuing the under ground development and further op- erations by churn drilling. Regular shipments of two cars a week of the copper ore is now being made, which will be increased to daily within a very short time. It is the intention of the Atlas company to construct a concentrating plant of not less than 300 tons daily capacity, the plans now being under way.
 The Atlas company is incorporated under the laws of the state of Arizona, with capitalization of $1,0O0,OOO, di- vided into 100000 shares of the par value of S1.0O each, fully paid and The Arizona officials of the Atlas Copper company are among the best known business and mining men in the copper state, and while some of the stock is being han uACu OAA LAAC -NCW I OIh NuADS LAACSC l4Cn have invested their money toward making the Atlas one of the big pro ducers of Arizona.

Clayton, Stafford, Arizona; sec retary, T. J. Sparkes, Phoenix; assist ant secretary, Morrison Han1ins, 34 Nassau street, New York; director, Gus Hirschfeld, Hayden, Arizona.
 The consumnation of the deal for the taking over of the San Juan mine by the Atlas Copper company is due largely to the efforts of Lewis A. Dunham, well known mining author ity. In commenting upon the Atlas copper, Mir. Durham said: q believe the Atlas copper is the best partially developed copper mine in Arizona In addition to the tonnage already indi- cated, the prospects of finding a fur ther considerable tonnage of ore of the same average value are excellent."' p
