It is reached from Santa Ana. on the Sonora railway, by an excellent wagon road. Distance S5 miles There IS also a good hard road from Tucson, 125 miles The regular cost of freight ing from Santa Ana to the mine is s2o in Mexican money. or $lO in gold, per ton. The elevation of the property was not ascertained exactly, but must be from two to three hundred feet low CT than the Montana Verdi, or from HOO to 1900 feet above sea level. The group comprises 76 pertenencias, or abo,rt l9O acres. Like at the Montana Verdi good timber is within convenient distance, and water for operating a plant and for domestic purposes is available. In fact water sufficient Tor smelling purposes has been encounter ed in working the property. The sur face formation is entirely different from that of the Montana Verdi, being characterized by we'll defined ledges having a general easterly and westerly trend. Across three of the largest or these lodges lying parallel and appar- ently constituting parts of single formation, 1t is probably 300 feet l Nearly all of the work upon the group has been done upon ledge or vein which may be readily traced for over ! 2,O00 feet on the property, and crops boldly for a distance of 1.40O feet. It's average width at the surface is eight feet, and it dips 69 or 70 degrees north, and has every appearance both apoVe and below the surface. of a true Assure vein. Upon this shaft was sunk by the former owners of the property 10 | a Cepth of iGl feet Al the 50-foOt level | a stat ion was cut on the northerly 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 -ha,f of it was in vein matter prop 1 CT. A winze was then sunk twenty four feet on this vein when water was struck in such quantities that 1t could no. be handled with their double wind lass, and the winze was abandoned. | A drift or tunnel was then driven hori- zontally on the ledge from the station for a distance of over i2O feet In this drift the vein shows width of from seven to nine fset and is plainly trace able it's entire length. The vein mat
 ter is quartz, feldspar and tale. The l copper occurs in the form of cha'co- pyrite and bonite. Assays of average saT pies across the drift, and for its entire length. shows tne ore to be very ! uniform in general and to run from | four to eight per cent in copper. Be- { low the 51-foCt level the vein inclines l entirely away from the shaft, and the formation of its walls down to the
 bottom from that point, as nearly as could be ascertained. is a soft granite. At the 154foOt level a cross cut was
 run to strike the vein. This part of
 the work could not be examined owing
 to the fact that there was still about AS
 fact of water in the shaft; but the former owners stated that in this cross
 cut they passed through A feet O. granite and F feet of mineralized vein
 matter when great flow of water was encountered forcing them to abandon the work. The water appeared to
 come from regular Assure. probably
 the same that was entered by the winZe above They managed. how ever. to enter this Assure three feet and obtained some samples before they were driven out by the water. It was estimated that at this cross cut there must be from 12 to l5 feet of vein mat ter yet to cut before reaching the hang ing wall. The vein matter is more than double the width here that 1t Is in tha 50-foot tunnel above, and the quartz. feldspar and clay seams or tale
 are in the same relative position. haV- ing Cn,y greatly increased in width. The samples upon being assayed were
 found to contain a greater percentage
 of copper than the ore in the drift labove. The Assure on the surface does
 not contain T large percentage or cop
 per. but it is found in the form or sul-
 phiGzs almost altogether. At depth of thirty feet in the shaft the ore IS
 much higher grade. running from to
 per cent, and is quite uniform in char
 acter. The assays taken as whole.
 show that the ore in the Assure contain
 from three to five dollars to the ion III
 gold and silver values.
 From the present development any
 nractical mining man would be con- . yinced that the property is mine, Tor there Is every certainty of cutting a
 great width of vein at depth of from
 three to five hundred feet.

 the company on this mine after the l water has ne II TeUiuNSu, ID 'HN

 full width of vein has bsen cut, ana
 the continuation of the shaft to the

 the headway that had already peen

 from that time Some provision VIII
 have to be made for the constant HOW
 of water. but the probabilities are that
 the great inundation of the shaft was due to the water reservoired in the hs"

 cut. and that there will be littie difil- culty in handing it once the shaft ana Assure are drained.
 The cost of labor is the same as at he
 Montana Verdi. The company now
 have at work all the force that can pe

 tinue on at the rate of two shifts a
 day.
 l There are three excellent prospects ; in the San Jose group outside of the mine itself. The ore in these Is Tn the form of carbonates and oxides and IS
