EUREKA DISTRICT CON-
 TAINS RICH DEPOSITS.
(From Sundays DailxN

hNtchsiVc development operations are now being conducted in n section of the Eureka mining district, tho de. tails of which little is known to the busy world of mining men in this sec. ton, the majority of whom, nt present. have their eyes on that land of promise, the new A. A C. country, just being opened up.
 Isolated, as the Eureka district is. from telcphonic, tclegraphic or railroad communication, but little is heard of the great wealth stored in the fastness. cs of the Boulder and Burro Greek sec. tions of that district, and the secrecy with which the affairs of the mining companies operating there arc guarded, aids in this state of affairs.
 Despite this it is nevertheless a fact that eminent mining engineers, of ma. tional reputation, who have made cx pert examinations of properties in tha, district. are responsible for the state. ment that the properties now being developed by the American Mines and Exploration company, and Joseph L. Glroux and his associates, contain de. posits that will rival in extent and rich. ness the great deposits which have made the United Verde, at Jerome, and other copper properties, the talk of the world
 Included in the holdings of Giroux and his associates, which cover the gratcr portion of stretch of noun. tain and mesa nearly six miles in length and four miles in width, is n townsitc, recently located at the june. tion of Boulder and Burro Greeks. in both of which permanent streams of water run the entire year around. Un. der the direction of the concern. n corps of engineers k now in the field making preliminary surveys for n rail road to connect with the \. r. P. & F.. main line at one of the several points now under consideration.
 A large air compressor and two com pletc hoisting plants are now cn route to the camp, to be installed on dcliv. cry, while five tunnels are being run into the great mountain of porphyry and conglomcrate, all of winch are in ore carrying good copper values. The lower tunnel will tap the apex of the mountain between 100 and 800 feet in depth. Good progress is being made on all the openings, the ground being of such nature that it is easily mined.
 Adjoining the group is the voge and ilise groups. numbering about fifty claims, being developed under bond by the American Mines and Exploration company. Los Angeles corporation. In harmony with the development car. red on by the other concern, this com pany is also opening its properties by series of five tunnels. Although only few months have elapsed since SC. curing control of the groups this con. ecrn is SO we'll encouraged by the ex. tent, character and value of the ore dc. posi,s tapped, that its directorate has now under consideration the ins,alla- ton of air compressor and hoists for the prosecution of m extensive plan of development. In addition 10 its min eral holdings the company also controls water rights with m ample supply of water at all seasons sufficient for the demands of large reduction plants, which will necessarily follow the de. velopment of the property into the pro ducing class.
 In addition to these two concerns, which have not yet fairly started, a number of smaller companies and pros. pectors are developing promising prop critics in the section, among which may be mentioned ]. B. Sloan of New York. who Is engaged in sinking shaft on one of his group of seventeen claims, which Is already producing shipping ore.
