COPPER MOUNTAIN HAS
 EXCELLENT SHOWING

The Copper Mountain group con sists of eight full claims, each claim 600 by 1,5OO feet, covering an area of I60 acres of surface ground, To- eated in the Helvetia mining district, eight miles south of Vails station, on the Southern Pacific railroad, the nearest shipping point. A wagon road leads to the mine. The development consists of shafts and open cuts, all showing copper ore. The principal work is on the Copper Mountain and Aleck. On the Aleck there are two shafts sunk on the rim of the ore deposit. One shaft in the center of the claim, 35 feet in depth, showing sulphide ore three feet from surface to the bottom. Twenty-one tons of sulphide ore were recently shipped to Fl Paso from this shaft. The widest part where this ore was stopped is at least five feet in width at a point fifteen feet from surface. This stoping was done under lease and left the shaft in bad shape however, the ore is persistent, and gives every evidence of permanency and widening in depth. There is no doubt but large bodies of even higher grade ore will be encountered; and a permanent supply of shipping ore de- veloped in further work. Another shaft sunk to depth of 12 feet, about 150 feet east of No. l on the same vein, shows considerable car bonate ore, and proves the vein to be continuous; in fact, the surface crop ping is strong and can readily be traced the entire length of the claim.
 The results of the twenty-one tons shipped to Fl Paso smelter gave re- turns of eight per cent copper; two ounces silver; 25 per cent iron and 2I per cent sulphur.
 The cost of treatment was only $2 per ton, proving the ore to be ideal smelting material. The shipment gave $21.53 per ton. The freight to Fl Paso was s9.65 per ton and the cost of hauling to Vails station, a distance of eight miles, s2 per ton, leaving a balance of $13.s3 per ton, allowing 8 per ton for extraction. This class of ore will net sIO per ton and by judieious development and partial equipment of the property, which should not exceed s5,O0O from 50 to 100 tons of this class of ore or better, could be shipped weekly with every possibility of a steady increase in production.
 The Oxide claim is located from northeast to southwest, and adjoins the Copper Aleek on the north side line, being an extension along the same mineral zone, consisting of well defined contact of earboniferous lime and granite, diorate forming the foot wall. Silieified lime associated with iron oxide and epidote, eapping or overlying the ore bodies. Along the contact on the oxide, there is considerable ore showing at inter- vals, principally in the form of green earbOnates and red and black oxide of copper. This is a valuable claim, but the ore cannot be figured on commercially until further work is done. There are only three shafts and two open cuts. The deepest is IS feet, but all showing ore.
 The Copper Mountain claim is To- eated from northeast to southwest 5000 feet north of the Oxide, and has a remarkable sur face showing or mineral. While the claim is located on a small butte, and being the lowest ground and nearest the valley, it gives the strongest geological evidence of de- veloping into a very valuable min eral deposit. Of course, copper pre- and while the develop ment is limited to a 4O-foot shaft 1 and some open cuts, at the bottom of the shaft, a erosseut was started and run 14 feet, but did not reach the mineral body, showing occasional punches of sulphide in the iron cap ping. (Homatite and magnetic con- -aining carbonate of copper and some bOrnite near surfaee).
