Large Reserves of Ore in Giroux Con-
 solldated

Stock market interests are becomins convinced that the attention given t( the stock of the Giroux Consolidated Copper Company, which has advanced in price more than 3$ a share since the first of the month, selling this week up to l0S, is founded upon the reports that have been coming from the property. Holders of other Cole. Ryan issues, particularly Greene Can. anea and North Butte, have been transferring their interests to the Ely proposition, which accounts for the buying movement recently apparent, but this midsummer incident has the encouragement of actual physical de- velopments, which, in the hands of the new management, have been advanced with speed that is fabricated by the ample funds provided when the enter- prise changed control.
 The activity in Giroux is evidently serving as one of the best influences in stirring up interest in the mining stock market. especially among the low-cost coppers. The steadily ad- vancing price has been ascribed to systematic support, but, aside from the fact that the middle of July is hardly suitable time to start manipulative tactics, the reports from the Nevada copper camp seems to offer more obvious explanation.
 The Giroux management is pursuing explorations with celerity that the ground has never before enjoyed, and, though official statements are not forthcoming, the general information gathered indicates that important re- suits have been secured by churn drill for distance of 1000 feet east from the Giroux shaft Without con sidering values, the topography of the ground gives the company very con- venient dumping ground in the canyon to the south for the disposition of the overburden, thus making the proposi- tion ideal for steam-shovel operations. But the outlook for copper values is being talked of as the most important phase of the developments. It is said that the drilling operations have re- vealed an immense body of porphyry running on an average of 3 l2 per cent copper, with gold values sufficient to pay large part of the cost of min ing and reduction. The prediction, unsupported by official statements, is made that this territory will be able to output copper at less than cents a pound, provided, of course, that the Cole Ryan interests are able to pro- vide economical means of reduction the most important problem which they have to solve. The settlement of this question has not yet been made, so far as the public knows. The Cole Ryan interests are not so frank about their purposes as some others in the business of milling low-grade copper ores.
 The porphyry body here referred to is estimated to average l50 feet in thickness and lies from 50 to 75 feet below the surface, which will be strip- ped off. The drilling operations indi- cate that the body thus far measured is about 2,O00 by 400 feet in lateral dimensions. Between 40 and 50 holes have been put down to make these de- terminations. Some of the ore is said to run as high as per cent copper, while the gold values are placed at about 40 cent a ton. Assuming that the ore is concentrated at the rate of 15 into one, with a metallic loss of 25 per cent, the concentrates will thus carry about 4.5Os in gold per ton. Off, setting the gold values against cost of copper production, this figure will re- duce the copper cost per pound as much as half cent.
 It is stated that this ore body is greater than the amount already dem- onstrated in the mine.
 The Giroux management has placed an order for 75O.OO0 feet of timber and lumber for the new shaft, situated about 800 feet southeast of the old AL pha shaft, and several carloads of the material have been delivered at the mine. Ten drills have also been or dered for use in the new shaft.
 On the 1,00O-foot level the first set
