they have taken out ready for crushing |
from 1000 ], 200 tons of ore. Their fine
new mill will be in operation before long,
when reduction will begin and continue
night and day. If expectations are real
lied, Highland will develop into one Of
the richest silver producing districts of
the State; and we have great confidence
in the success of the Mendha Company's
enterprise. The first ledge in order of
consideration is
THE MENDOZA NINE.
1t is about a mile and three-quarters
west of the Mendha mill, the principal
developments being in and on the east
rim of well-wooded canyon which the
ledge crosses from east to west. The
mine is 1900 feet above the sea level,
and 200 above the mill-site. just below
the developments the canyon opens out
into beautiful grassy glen, with over
hanging cliffs covered with cedar and
dwarf pine. The country rock, through
which the ledge trends as far as opened,
is grained grey limestone. The
ledge runs almost directly east and west,
and can be traced by the groupings for
hundreds of feet. A tunnel has bsen
started on the west side and at the bottom
of the canyon, and follows the ledge in to
the westward distance of three hun
bred feet 1t is AZ feet wide and 6 high.
Work continuesi in it, and it will be driven
in 400 feet further, ut least, before
suspending operations. The dip of the
vein is from the south to the north, the
incline being about IS deg. The vein
varies in width from the mouth of the
tunnel to the face from six inches to five
feet, but its average extent may safely be
set down at two feet, as it is strong and
well defined the greater distance. At
point $50 feet from the mouth of the tun
mel it widens out to six feet, the ore be-
| ing very rich, assays running from $50 to
| $500 to the ton. This, too, is about the
range of cropping assays, the ledge being
| as we'll defined for 700 feet on the surface
as in the tunnel. The tunnel at its face
is 40 feet below the surface, but the
ledge crops out on the surface 700 feet
west of that point. The ores are of the
sulphuret class, carrying large per cent
ages Of lead and iron. Professor Mathey
feels great confidence in his ability to re-
duce them and save all the silver; says
he has had considerable experience in the
| reduction of similar ores. The vein
walls are of the same general formation
as that entire district lose-grained grey
limestone. Between the vein matter and
walls there is thin layer of pure white
lime, which leaves its mark on what it
touches like chalk.
THE MAIN SHAFT
OF the Mendha mine is 306 feet east of
the tunnel. 1t is now down 21O feet,
The ledge at that point goes down straight
great distance, the shaft following it
the first 100 feet. 1t then dips to the
north. Where the shaft leaves the vein,
100 feet down, the mineral body is 13 feet
wide, but the ore is low grade, the average
assay being $73. The average width of
the vein to the first level is set down al
three feet, much of the ore being high
grade, assays running as high as $4Oo to
the ton.
At least 600 tons of ore have been taken
ont of the tunnel and main shaft of the
Mendha mine, and only "dead work, sc
far, has been done.
Excellent steam hosting works are ir
operation, with blacksmith shop con
nected. Attached to the engine is {
tirst-class condenser, and the mine il
aired by the patent noiseless fan-whee
ventilator.
The contiguous hills are covered will
growing timber admirably adapted to al
mining purposes.
The Mendha mine was discovered by
party Of prospectors in the fall OF 1869
They got the name from the Indian he
rome of one of Ned Buntline's famous
, border tirtions.
/ THE ARIZONA NINE
3 Is also owned by the Mendha com
pany. 1t is reached by ascending tn
mountain to the east of the Mendh
= mine to its summit At the discov ar
3 shaft it is S,400 feet above the sea level
e The formation it is in is the same as tina
1 of the Mendha, and the ore looks Il:
: much like the Mendha ore as one pei
/ like another; but, strange as it ma
Q seem, the vein, at discovery, is as fiat a
) floor, and trends north and south
D while the Mendhas trend is east an
n west The vein, in some places, is
Q feet wide, and in no place developed ha
v it fallen below feet. Six hundre,
o tons of the ore are out, and 5000 tons
n at least, are in sight. Some of it assay
t. as high as $3.50 to the ton, and it ha
Y never fallen below $40. OF course thi

/. yards below this immense mass of OF

ID in the same direction, with about th
d same dip, and between exactly the sam
walls, as the Mendha, mile to the ives
r No doubt they are one and the SAN
ledge. Professor Mathey himself disco
