 of Jerome, is owned by the Hayden Development Company. and no de tails regarding the strike have been made public. It is known. however, that contract has been let for the freighting of 30 tons of copper ore daily to Clarkdale, to be shipped from that point to one of the smelters in the southern part of the State.
 For years the Copper Chief was supposed to be only 9 gold and silver mine. It mas splendid surface show ing of gold ore. The main ledge is 20 feet wide from the surface to the 16O-foot level, and it averages s ton in gold and silver.
 At 300 feet drift was run l50 feet, all in copper orc averaging per cent. At $50 feet, the present depth of the shaft, the ore is much higher in cop per. It is from this level that the ore to be shipped is now being stopped. It is silicious in character.
 A tunnel taps the shaft at $50 feet and through this the gold ore mined above the 160-foot level is trammed out to the mill The plant, which is tube and ball mill with cyanide plant, is treating l25 tons of orc day and saving 70 per cent of the values. It was completed only last October and is one of the most modern mills of its type in the Southwest
 James Wellington Finch. the noted geologist and mining engineer, is now at the Copper Chief making an exam ination. It is understood that he is formulating plan for the develop ment of the unexpected copper de- posit.
 Shea Copper Co.
 Just south of the Copper Chief, but on somewhat lower ground. lie four patented claims owned by D. J. Shea, one Of Jerome's most prominent mer- chants. The surface showing is fully encouraging as on Copper Chief ground but the copper values arc much higher and the gold values less. About S5.0O0 worth of work has been done. Several shallow shafts have been sunk and some short tunnels have been run. All are in orc; at no place has either wall of the ore been cut. There are eight or nine out crops, all running well up in copper.
 Dundee-Arizona
 The Dundec-Arizona property con- sists of two patented claims. the Green Flower and Green Up. lying on the south slope of the "Hogback" and less than half a mile out of Jerome. They were held a number of years by r. s. Stephen and Alexander Mac kay Stephen recently organized the Dundee-Arizona Mining Company, with 5OO,0OO shares. par value Sl. The owners received 275,0O0 shares for the property and the remainder was talk en over by a syndicate of Phoenix business men who sold 100000 shares at par. The history of the financing of the Dundee-Arizona affords close parallel to that of the Green Monster Company, for the stock offered for sale was greatly oversubscribed.
 Cutting through the claims for distance of 700 feet is ledge of con glomerate. stained a vivid green and averaging all the way from 6 to l2 per cent copper right on the surface. \ tunnel has been driven into this ledge 264 feet. It soon passes through inc conglomerate and enters the lime, which is also heavily imprcgnated with copper There arc frequent water courses through the lime and from their walls samples running as nigh as 90 per cent copper can be broken.
 From the 1O0-foot point in the tun- nel a shaft was sunk 100 feet into the lime, and the copper values held. 4 raise was then started to connect with q shaft sunk 65 feet from the surface. When 70 feet above the tunnel levcl and within five feet of the shaft. the raise chippcd into the edge of blind ledge Of lime carbonate and glance averaging g per cent copper. This ledge was penetrated only last Fri day and there has been no opportunity 10 determine its extent.
 A site is being graded for a saso- line hoist that is on the way. When this machinery is in place the slaft will be sunk 10 a depth of 1000 feet.
 Nine men arc now employed under the direction of Superintendent ]. A.. Hubbard
 The Jerome Verde.
 The Jerome Verde Company. which owns 2S patented claims surrounded ol three sides by the United Verde. U. V. Extension and Dundee-Arizona. is not now doing any development work on its own account but is short ly to let contract for the construc- ton of 2,lO0 feet of road to connect with the location chosen for a new shaft site. This road will cost about S4OOO. As soon as it Is completed machinery will be installed and the shaft will be sunk to d depth of a; least 1000 feet.
