 erly of the Montana Verdi a distanC
 of about 5 miles, and is approximat,
 ly 65 miles from the Gulf of Califor
 mia. It is reached from Santa Ani
 on the Sonora railway, by an exec
 lent wagon road, distance S5 mile
 There is also a good hard road frol
 Tucson, 125 miles. The regular co.
 of freighting from Santa Ana to tn
 mine is SEQ in Mexican money, CT S1
 in gold per ton. The elevation of tn
 property was not ascertained exactl
 but must be from two to three huI
 dred feet lower than the Montan
 Verdi, or from 100 to 1900 feet abov
 sea level. The group comprises '
 pertenencias, or about 190 acres. Lik
 the Montana Verdi, good timber
 within convenient distance, and wat CT for operating plant and for dc nestle purposes is available. In fac water sufficient for smelting purpose has been encountered in working tn property. The surface formation entirely different from that of tn Montana Verdi, being characterize by well defined lodges having a gen orally easterly and westerly trend Across three of the largest of thes lodges lylng parallel and apparent, constituting parts of the single forma tion, it is probably 300 feet. Nearl, all the work upon the group has beel done on ledge or vein which ma, be readily traced for over 2OOO fee on the property, and crops boldly fo distance of 400 feet. Its average width at the surface is eight feet, anC it dips 69 or 70 degrees north, anc has every appearance both above anC below the surface of a true Assure vein Upon this shaft was sunk by tn, former owners of the property to { depth of 16l feet. At the 50-foo level station was cut on the mortimer ly side of the shaft back to the center of the vein which had inclined away from the shaft until at this point only about one-half of it was in vein mat ter proper. A winze was then sunk 24 feet on this vein when water was struck in such quantities that it could not be handled with their double and the winze was abandon ed. A drift or a tunnel was then driven horizontally on the ledge from the station for a distance of over 12C feet. In this drift the vein shows a width of from seven to nine feet, and is plainly traceable its entire length The vein matter is quartz, feldspar and tale. The copper occurs in the form of chalcopyrite and bonite. As says of average samples across the drift, and for its entire length, shows the ore to be very uniform in general and to run from four to eight per cent in copper. Below the 50-foot level the vein inclines entirely away from the shaft, and the formation of its walls down to the bottom from that point, as nearl y as could be ascertain ed, is a soft granite. At the 154-foot level a crosscut was run to strike the vein. This part of the work could not be examined owing to the fact that there was still about IS feet of water in the shaft; but the former owners stated that in this crosscut they passed through A feet of gran ite and 12 feet of mineralized vein matter when great flow of water was encountered forcing them to abandon the work. The water appeared to come from a regular Assure, probably the same that was encountered by the winze above. They managed, however, to enter this Assure three feet and obtained some samples be- fore they were driven out by the wat CT. It was estimated that at this crosscut there must be from 12 to 15 feet of vein matter yet to cut before reaching the hanging wall. The vein matter is more than double the width here than it is in the 50-foot tunnel above, and the quartz, feldspar and clay seams or tale are in the same rel ative position, only having greatly in- creased in width. The samples upon being assayed were found to contain a greater percentage of copper than the ore in the drift above. The fs- sure on the surface does not contain a large percentage of copper, but it is found in the form of sulphides all most altogether. At the depth of 30 feet in the shaft the ore is much high CT grade, running from f to- per cent, and is quite uniform in character. The assays taken as a whole. show that the ore in the Assure contains from s to s a ton in gold and silver values.
 From the present development any practical mining man would be con- vinced that the property is a mine, for there IS every certainty of cutting a great width of vein at depth of from 300 to 800 feet.
 The development work planned by the company on this mine after the water has been removed, is the exten- sion of the 154-foot crosscut until the full width of the vien has been cut and the continuation of the shaft to a depth of 300 feet where another cross. cut will be made. The water was be- ing removed by means of whip and from the heaGway that had been already made since work was started the shaft must have been drained il ten days from that time. Some pro vision will have to be made for the constant flow of water, but the, proba- Utilities are that the great inundation of the shaft was due to the water res. ervoired in the tissue above where il came into the crosscut, and that there will be little difficulty in handling il once the shaft and Assure is drained
 The cost of labor is the same as al the Montana Verdi. The company now have at work all the force that can be worked to advantage, and will continue on at the rate of two shifts a day.
 There are three excellent prospect. in the San Jose group outside of the mine itself. The ore in these is in the form of carbonates and oxides and i, found in veins three to five fee wide, one of which can be readil, traced for long distance. Anothel is capped on a hill by an immens, hematite iron mass which itself carrie. copper. All these have good wagor roads from another and to the mine.
 Ten additional pertenencias hay, been taken up by the company aIon, the side lines of the San Jose to pr,
 vent possible future interference.
 Although freighting by wagon t,
 and from Altar, or even Tucson is no
 expensive owing chiefly to the spien
 did roads, it will not be long that thi means of transtlortatiou will ba,,s (,
