THE VOLCANIC Gold and Silver Mining and Smelling Go. Formerly Called the Volcanic Copper Mining and Smelling Co.--A
 Detailed Report Of Their Phenomanal Gold and Sil- yer Strike In the Eagle Tail
 Mountains.
Location and size of Mines.

Arizona, near the line of Maricopa and Yuma counties, being in Maricopa county and about 35 miles due north of Sentinel on the s. P. Ry., and 25 miles south of the Bonanza, T. 2N. R. 10 west. They are situated in the foot hills of the Eagle Tail mountains, Cathedral Rocks and near an extinct volcano crater, which is two and one- half miles northwest of the mine.
 Amount and Size of Claims.
 The Volcanic Copper Mining and Smelling company's property consists of the original find, known as the Vol taire Mine, running east and west on the lode l500 feet by 600 feet wide. On both sides of the Voltaire we have the Barber and Hunter lodes, running east and west l500 by 600 feet wide. On the east and west ends of these lodes we have the Lower and Volcanic mines. l500x600 feet, running northwest and southeast. The five claims covering about 100 acres of rich mineral ground almost in a solid square. In addition to these five claims, the company owns the Columbia consisting of rich gold deposit one mile northwest.
 THE DISCOVERY AND LOCATION.
 A portion of this vast deposit of cop per, gold and silver ore was first dis covered by Pedro Ledesmo, a scout and interpreter for General Crook. In the winter of 1873 the president ordered Gen. Crook to proceed from Yuma and take out Geronimo and his msrauding band of Apache Indians from the vicin ity of the Eagle Tail mountains. It was during this trip that Ledesmo discov- cred one of the mines and after some 10 years later, the Apache Indians hay. | ing been subdued, he related his find to mining engineer and assayer by the name of A. J. Porterie, who, after several unsuccessful trips, finally found and located it in the winter of 1890. He located one claim 1900 by 600 feet, assayed the ore and found it to be very rich in gold, silver and copper, and as he then thought, copper predominating He called it the Votaire, and about April 4th 1893 sold his claim to the Volcanic com pany of Phoenix for con sideration of $l50,O00.OO. After this purchase the com pany secured the tve other clans above referred to.
 THE EXTINCT VOLCANO AND THE LOCATION OF THESE MINES.
 At a point about 21a to miles south east of the large crater, and about mile southeast of the Eagle Tail Moun- tains, out on level plain are seven low hills or buttes, rising gently from the valley, perhaps 95 feet from the plain below. These cover an area of about 100 acres, which embrace the mineral deposit. The lodes, or veins, run through and over these hills south east and northwes The ore is found in large Assure veins at intervals of 10, l5 and 20 feet, running southeast and northwest. Across the hills these veins crop out at intervals on top of these buttes on the slope and on the plain be- low and in the creeks southeast of the buttes mile from top of buttes and some 80 feet lower. These veins are in place and vary in width from . to 40 feet. Describing the occurrence and formation of this vast deposit from a geological standpoint, the ore appear ing in these Assure veins or openings was forced up from the bowels of the earth below by the expansion of the granite or quartz formation, (being the composite rock of the hill formation), during the time the crater near by was in active operation. While the rocks were expanded the ore was shootingup- wards and az the rocks cooled the ore was held in place where we now find it. THE PRINCIPAL MINERALS FOUND ON THESE
 SEVEN BUTTEs OR HILLS,
 Are gold, silver, copper, lead iron oxide, flour spar, lime, carbonate of copper, copper glance, copper pyrites, black OK ide of copper, red oxide of copper and manganese. All of the above emu ner. ated minerals render this ore a perfect natural Aux for it's reduction with smelters. The color of the ore is dark brown. and red. The ore of the various veins have been assayed by the best as- savers of Phenix. The lowest assay run $l99. 40 gold, SIS 80 silver and l2 per cent copper per ton. The highest assays run $l, ,l93.30 gold, $lS60 silver, and B per cent copper per ton. From these figures you can compute general aver age of the whole which makes this de- posit. Ten times the richest mine ever discovered on the continent. Up to this date these veins or lodes have not been sunk upon over to 10 feet, but at numerous places and wherever opened there is ore in great abundance, and all is pay ore from the grass roots down. A regiment of soldiers could be worked on the outcrop pings of these veins and each man have ample room to work.
 THE COLUMBIA A vERITABLE GOLD HILL.
 This is one of the companies big finds. It is located about one mile northwest ot the Seven buttes just re. ferred to. This hill rises up from a level plain that surrounds it and is com. posed entirely of a dark yellow and dark brown rock intermixed with melted quartz. Each and every rock is separate and apart from the others. This hill covers an area of about ten acres. On the north end of this hill about 200 feet from it's base is wide dark quartz vein about 35 to 60 feet wide showing free gold this vein runs under the hill and again shows itself on the south end. Climbing the Ill we find that the entire formation of this
