Yuma County Is Now Sharing With Yavapai Benefits Ac- cruing Through Discovery of Promising Ore Bodies.
COPPER BASIN MINES
 ARE PROVING GOOD
Boston & Jerome and United Verde Consolidated Among Properties Which Will Be Listed on Curb.

! PRESCOTT. Ariz.. Nov. 1S.-Inter- copper properties. until recently large | ly confined to the Verde district. is expanding to other sections of this and the adjoining county of Yuma. The movement gained it's initial mo- mentum from copper ore discoveries of more than ordinary importance made some months ago in the Loma Prieta mine in the Copper Basin sec tion of Yavapai county. and in the Harqua Hala Bonanza mine in the Harqua Hala section of Yuma county. There is reason to believe that both of these properties will in due course become regular producers of copper ore in large tonnage. and that each will be instrumental in demonstrating the copper-ore-bearing worth of the entire district in which it is located.
 Copper Basin Mines The Commercial mine in Copper Basin. owned by the Phelps-Dodge in- terests. is shipping from SO to 100 tons of copper ore daily to smelter. and could increase the daily tonnage considerably were it not for the fact that smelting facilities are not keep ing pace with the output of Arizona's mines, either in this or the other min ing counties of the state Adjoining the Commercial mine is the property of the LOma Prieta company. where body of ore carrying general aver age of 21a percent copper to the ton is being developed. A small tonnage of sorted ore of the dump samples about l5 percent copper The proper " is to be equipped with a modern plant of machinery and developed at depth. The present depth of the shaft is 155 feet. and it is in a solid body of chalcopyrite ore from the S0-foot point down.
 Copper Hill Promising
 The property of the Copper Hill company. a corporation dominated by E. s. Clark and John J. Jackson of Prescott. is another Copper Basin mining enterprise for which a highly productive future is predicted Next to the Commercial mine. the Copper Hill has been developed to a greater extent than any mine in the Basin. Commercial grade copper ore is ex- posed on three levels and has been stopped to some extent above each Several shipments of ore have been made at a good profit. The mine is in general in excellent shape for fu- ture production, depth and develop ment taken into consideration. Other properties in Copper Basin having copper ore showing above average are the Shumate. Schuber. John II. Rob inson. Blickenstaff. McBride-McNulty and Lucky Five.
 HarqUa Hala Copper
 Mineral conditions continue to i'm prove as development work progress es on the Sth level of the Harqua Ha- Ia Bonanza mine. a Yuma county property in which H. William Stew ems and other mining men of Prescott are heavily interested. Hitherto worked as a good proposition. solely. t now appears probable the mine will in due course come to the fore as a copper proposition. Sulphide ore car wing 5.S percent copper was opened some time ago on the sth level in with a large body of oxi- lived ore carving high values in gold This ore body is standing the test of development, both as to copper and gold values. and is one of the most ever opened in the mine
