from tndt OF inc montana Nerul, Dcing
characterized by we'll defined ledges hav
ing a generally easterly and westerly
trend. Across three of the largest 0t
t these lcdges lying parallel and apparent.
r ly constituting parts of a single form
alton, it is probably 800 feet. Nearly I'll
OF the work on the group has been done
/ upon "A ledge or vein which may be read
, lily traced for over 1000 feet on the pro-
. perty, and crops boldly for distance OF
400 feet Its average width at the sur
face is eight feet, and it dips GO or 20
degrees north, and hasevery appearance
both above and below the surface, of a
true assure vein. Upon this shaft was
sunk by the former owners of the proper
ty to a depth of 16l feet. At the so 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
hall ot IT was IN vein matter proper. A
Wine was then sunk "a feet on this vein
when water was struck in such quaint
ties that it could not be handled with
their double windless, and the Wine was
abandoned. A diff or tunnel was then
driven horizontally on the ledge from
the station for distance of over 12O
OF from seven to nine feet, and is plainly
traceable its entire length. The vein
matter is quartz, feidspar and tale. The
copper occurs in the form ofchalcopyrite
and bonite. Assays Of average samples
across the drift and for its entire length,
shows the ore to be very uniform in gen.
eral and TO run from four to eight per
cent in copper. Below the so foot level
the vein nclines entirely away from the
shaft, and the formation OF its walls
down to the bottom from that point. as
nearly as could bc ascertained, is n soft
granite. At the 1854 foot level 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 AZ feet OF water in the shaft but
the former owners stated that in this
crosscut they passed through ~ feet OF
| granite and II feet OF mincralized vein
matter when great flow of water was
encountered forcing them to abandon
the work. The water appeared to come
| from regular flSsure, probably the me
that was entered by the witlze above.
| They managed, however. to eutcr this
hssnre three feet and obtained some sam
pies before they were driven out by the
water 1t was estimated that at this
crosscut there must bc from = 10 | 8
feet OF vein matter yet to cut before
| reaching The hanging wall. The vein |
| matter Is more than double the width
here that IL is in the so foot tunnel |
| above, and the quartz, icldspar and clay |
seams or tale are IN the same relative |
position. only having greatly increased |
| IN width. The samples upon being as |
sayed were found To contain greater |
percentage of copper than the ore IN the |
DRIFT above. The hssure on the surface |
does not contain "A large percentage of
copper but II is found in the form of |
sulpbides almost altogether. At depth |
OF thirty iect in the shaft the ore Is much |
higher grade, running from to per |
cent, and is quite uniform in character /
The assays taken AS a whole, show that |
the ore IN the fssurc contains from three |
to five dollars TO the ton in gold and |
silver values,
From the present development any
practical mining man would he couyinc-
ed that the property is "A mine, for there
is every certainty OF cutting a great
width Of vein at depth of from three
to flse hundred feet
The development work planned by the
company on this mine after the water
has been removed, is the extension of the
! 81 foot crosscut until the full width of
VEN has been cut, and the con iuuation
of the shaft to depth of 800 feet where
another crosscut will be made. The
water was being removed by means of
whip and from the Roadway that had
been already made since work was start
ed, the shaft must have been drained in
ten days from that time. Some provi.
sion will have to be made for the con-
stant flow Of water, but the proba bilities |
are that the great inundation of the |
shaft was due to the water rescrvoired |
In the fissurc above where il came into |
the crosscut, and that there will be little |
difficulty tn handling it once the shaft |
and fissure is drained.
The cost of labor is the same as at the |
Montana Verdi The company now have |
at work all the force that can he worked |
to advantage, and will continue on at /
the rate of two shifts day.
There are three excellent prospects in
the San Jose group outside of the mine |
itself. The ore in these IL in the form oil
carbonates and oxides and is found in
veins three to FIVE feet wide. one of which |
can bc readily traced for long distance.
Another is capped on hill by an i'm
mcnse hematite iron mass which itself
carries copper. All these have good wag-
on roads from one another and to the
mine.
TEN additional perteneicias have been
taken up by the company along the side
lines OF the San Jose to prevent possible
future interference.
Although frcighting by wagon to and
rom Altar or even Tucson is not expen-
sivc owing chiefly to the splendid roads.
It win not be long that this means OF
transportation will have to be depended
upon. for a narrow gauge railroad isnow
under process of construction from
point on the Gnlf of California to Altar
and probably to connect with the Sonora
road. Prom statements made by Mr..
Holmes. who ID the chief protector and
manager of the road il was learned that
the route already selected will bring il
within short distance from both pro-
pertics, and particularly the San Jose,
that route being naturally the most fa-
vorable for construction.
Messrs. Mitchell and Cordiner express
themselves as more than satisfied with
the properties, and icel safe in saving
that the representations made as to
their merit prior to the first issue OF
stock fell far short of doing justice.
