to 10 per cent copper. It is the in-
 tention of the company to continue the shaft at a depth of 100 feet, and then
 drift through the ore body. A large
 force of men il now at work.
 It Is impossible for any person to look over this group, to walk over and among the masses of minsralzed rock and note that characteristic greenish appearance everywhere in evidence,
 without forming the positive conviction that underneath his feet lies hidden an immense body of copper ore. greater perhaps, if the indications count for anything, than has ever yet been un- covered. He cannot be brought to the
 b lief that this copper ore came from any other source or airs ction than be- low, nor that the visible copper in the ore was deposited upon the crest of the hill whsIe ths ore occurs, by the action of any surface stream. But though he win conclude his inspection of the Mon tana Verdi with the firm conviction that a little development work will q smonstrate what app ars now so evil dent it is not until the visitor reaches the San Jose group, the other property of the company, and makes his exam ination that h. feels warranted in say
 ing that the company has mine the
 character of which as such Is assured.
 The San Jose group lies north -Westcr- ly of the Montana Verdi, a distance of about 55 miles, and is approximately G5 mics from the Gulf of California. It is reached from santa Ana, on the
 Sonora railway, by an excellent wagon
 road Distance S5 miles. There is also good hard road from Tucson,
 125 miles. The regular cost of freight ing from Santa Ana to the mine is $2O in Mexican money. or $lO in gold. per ton. Ire elevation of the property was not asc6rtained exactly, but must
 be from two to three hundred feet low CT than the Montana Verdi, or from l7OO to 1900 feet above sea level. The
 group comprises 76 pertenencias, or
 about 190 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 for
 smelling purposes has been encounter
 ed in working the property. The sur
 face formation is entirely different
 from that of the Montana Verdi, bsing chai acteriZed by we'll defined lodges
 having a general easterly and westerly
 trend. Across three of the largest of these lsdges lying parallel and appar- sntly constituting parts of single
 formation, it Is probably 800 feet.
 Nearly all Of the work upon the group
 has been done upon a ledge or vein
 which may be readily traced for over
 POGO feet on the property, and crops
 boldly for distance of 1,400 feet. It's
 average width at the surface is eight
 feet, and it dips 69 or 70 degrees north,
 and has every appearance both above
 and below the surface. of true Assure
 vein. Upon this shaft was sunk by
 the former owners of the property to
 depth of 16l feet At 'the 5O-foot level
 station 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-haf of it was in vein matter prop
 er A winze was then sunk twenty
 four feet on this vein when water was
 struck in such quantities that it could
 not 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 distance of over 120 feet. In this drift the vein shows width of from
 seven to nine feet, and is plainly trace able it's entire length. The vein mat
 ter is quartz, feldspar and tale. The copper occurs in the form of chalco- pyrite and bonite. Assays 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. Be- low 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 nearly as
