BENSON. Oct 13.-Mr. H. F. Mer- Till. formerly the cashier of the Bank of Benson, has just returned from an inspection of the properties of the Keystone Copper company at John son, of which he is large stockhold- CT, and he says that the company will undoubtedly be one of the large cop per producers of the state. The work is in charge of U. R. Miller, and the main workings are on the Hagerman claim, where the main shaft has been sunk to a depth of 635 feet. The power house is well equipped with a large hoist, compressor blowers, substantial head frame 40 feet high, and everything necessary to carry on the work in a safe and economical manner; the rock is broken with power drills.
 In sinking this main shaft a fine body of shipping ore was encounter ed at the 40 foot level and continued to the 65 foot mark. and considerable drifting and stoping was done on this ore body, and many cars of high grade ore shipped to the smelters. Much ore still remains to be taken out. On reaching the 2S0 foot level body of low grade iron ore and sul- phide ore was broken into and it con tinued for a depth of about 60 feet. At the 312 foot level drifts and cross cuts were run on this ore body which shows up very promisingly, the rock being heavily impregnated with min eral shot all through the formation.
 It is the intention of the company to continue the cross-cut at this 312 foot level and until the hanging wall is reached, where ores of high value are expected to be found, it being the history of the mines in this district that all the high grade ore is found on the hanging wall.
 At the 500 foot level the sulphides are scattered all through the rock. In fact, the entire shaft from top to bottom is in ore or mineral of some kind, and in places it is of high grade.
 Adjoining the Hagerman claim on the northwest is the O. K. group. be- longing to this same company, and now being developed by incline shafts, with drifts and stopes. At a depth of hundred feet a body of high grade oxide ore was encountered and the drifts run on this ore body show it to be at least seven feet in width, with we'll defined walls which reach to the surface in some places. Sev- eral cars of rich ore have been ship ped from this ore body, and it cer- tainly looks very encouraging and worthy of more development work and exploration.
 The incline is about 200 feet in depth. A gasoline hoist has been installed, and the air drills are cut ting the rock for the blasts, the air being piped from the main power plant.
 Adjoining the O. K. claim on the west are the workings of the Cobriza Mining company. who are now ship ping from five to ten cars of ore daily and are preparing for extensive de- velopment work so as to continue their shipments.
 To the north and adjoining the o. K. group. the Thunderbolt Copper Mining company have recently bought number of claims, and are now erecting 4O-h p. hoist and com pressor and preparing to carry on development work to open up the 5howings which show on the surface and in the shallow openings sunk on the many lodges cropping out
