and wide.
 The Harqua Hala was discovered in 1888 and after a considerable tonnage of rich ore was taken out it was bought by an English syndicate for So, ,G00.000. The English company took out about S4,OOO.OO0. all above the 2OO-foot level. The ground was badly broken and at that depth the ore seemed to pinch out. Deciding that the mine was worked out or so badly faulted that to attempt to find the ore again would be fruitless, the English concern quit. Some time iat CT the Harqua Hala was sold at sher- ifrs sale. It was bought by John B. Martin, Dr. Ancil Martin, of Phoenix, and a Buffalo, New York, capitalist for $5,0OO.
 John B. Martin has been in charge of operations ever since. The prop .erty is now held under bond by the Yuma Warrior Mining company, a New York syndicate represented on the ground by H. William Stevens. Martin is employed by this company as superintendent
 When Martin took charge he pro- ceeded to sink the shaft to greater depth and crosscut to the north through what was supposed to be the footwall On the other side he found the ore, unbroken and as rich as ever.
 The vertical depth of the incline shaft is only 300 feet and the ore re discovered by Martin is being blocked out on three levels. On the lowest level drift is being run on sixteen feet of solid ore Next to the hang ing wall the ore is sulphide averag ing s4 ton in gold and 5lA per cent copper; the remainder of the ore is oxide which runs above $40 gold. streaks of it are fabulously rich.
 As depth is attained the sulphide increases in width and richness Eventually the Harqua Hala must be equipped with Notation plant to handle the sulpbine. At present twenty of the forty stamps in the Till are operated eight hours a day on the free-milling oxide taken out in the course of development. These twenty stamps reduce about 9 tons in shift Another battery of ten stamps will be placed iii operation within a few days.
 Porphyry:
 On a big flat just north of the liar qua Hala is big deposit of mineral ized porphyry, now held by the Mar tin brothers A shaft sunk in the mid de shows disseminated ore that car ries from one to five Der cent copper md from s1 to s25 ton gold. Cali fornia parties recently inspected this deposit and if they take it over it viii be churn drilled thoroughly.
 " =. Tank Pass. =. =. =.
 Though Tank Pass. seven miles northwest of Salome in the Harcu- vars, is an interesting mineral condi ton. Here is a great limestone chist belt, crosscut by a regular SC ries of diabase and diorite dikes run ming from northeast to southwest These dikes can be seen miles ava. with the naked eye. They are from 100 10 200 feet thick and can be tracef clear to Cunningham Pass, tifteer miles east. High grade gold and cop per ores are found on the contacts with the dikes or in close relation tC them. Surface indications of pay ore usually consist of either quartz an6 iron cappings or iron stains. A few feet of work usually is suppicient to open ore ranging from a few dollars ton up to several hundred. The ores of the Harcuvar range as a rule aver age from five to 8 percent copper ano from s4 to s100 ton in gold. The general character of the ore is the same all along the range except ir the limestone and chist replacements Many large iron outcrops remain un- touched and development for the most part has been confined to lodges and dikes where shipping ore has been found within a few feet of the sur face
 The Cobrita Mines company. a Los Angeles concern represented by D. W Hall, has taken over fourteen claims just east of Tank Pass and has g force of men taking out high-grade shipping ore. A shipment recently made averaged above fifteen per cent copper and values are steadily in creasing with depth some of the ore running as high as S65 in gold A hoist and other machinery are soon to be installed and then production will be materially increased.
 Fifteen men in the employe of the Cobrita Company are now building an excellent road through Tank pass which has ever been terror to Treighters. An entirely new road is tc be built along a "hogback" from the pass to Salome. This will be a tre- mendous benefit to the entre Tank pass country.
 The Tank Pass mine lies rhrough he pass in the limestone-chist belt and is cut by the dikes that carry the ore in the main Harcuar range. Its principal showing is seventy feet Of copper gold silver ore in limestone replacement. Sulphides have been opened up and the Tank Pass appears to be an ideal concentrating proposi- tion. Moneyed interests recently in spected the property and it is prob able that they will take it over at an
