THE MINES.


reduction this week. The west shaft is
down about 25 feet, following a well defined
vein Of base ore between 8 and 4 feet wide.
What The Moose now requires is adequate
hosting machinery to sink below water level,
as a great deal of the surface ore has been
stopped out. At the point where water was
reached in the main shaft, about four
months ago, the ledge was wider and the ore
fully 100 ounces richer than near the surface,
SO that every reason exists why the mine
should receive the benefit of a thorough de-
velopment. If the owners of the property
wOnld either work it themselves Or give an
extended lease on it to justify Tic lessees in
purchasing machinery, the Moose would soon
make a name for itself, but as long as only
short leases are given, the lessees very natur-
ally, may be expected to take out es erything
in sight and spend as little as possible in
prospecting for more ore.
The east shaft is expected to be emptIed
of water to-day. In the middle shaft the
east drift on the hanging wall side of the
ledge is being pushed vigorously ahead, and
is producing some very high grade ore of
which perhaps Is tons are on the dump. If
the drift to be run west from the bottom of
the east shaft should prove the per1nansnce
of the rich ore shoot opened up in the east
drift of the middle shaft, Mr.. Meadsr will
no longer delay the purchase of extensive
hosting machinery, and with a large force Of

speedily to reimburse him for the purchase
money Of 100000, and to make a proud
record for itself in the matter Of ore produc-
ton.
From the bottom OF the east shaft recently
sunk to water level, a depth Of IS feet, and
on a vein of ore the fall width of the shaft
from the surface to the bottom, a drift west
was started several days ago, which will con-
meet with the main level of the mine. The
Slopes in the east drift Of the main shaft are
yielding daily from ~ to 10 tons Of very free
ore. Only a small force is at present EN-
ployed on account of the great ease with
which the ore can be extracted. Five men in
the High Ore mine could keep a 2O-stamp
mill in constant operation.
DIAMOND.
Mr.. w. A. Clark. the owner of this proper
ty. is taking the necessary steps to open it up
in excellent shape. During the past week
the shaft has been we'll timbered, and either
to-day or to. morrow, sinking on the ledge will
be resumed. A whym will be put up in the
near future, and the shaft will be put down
to water level as expeditiously as possible.
Sinking has not yet been resumed in the
main shaft, but in all probability work will
be recommended in a few days, and drifts
started east and west on the vein, which in
the bottom of the shaft is fully three feet
wide, having increased steadily from the sur.
face. 1t would require but little further de.
velopment to place the Auraria on an excel.
lent paying basis. In the west Shaft, which il

which adjoins the Moose, the east drift ,;

AAGNA CIIARTA.
The new shaft house is rapidly approaching
completion, and is about 60x22 feet. The
shaft itself, deuble compartment, is dowl
about Is feet, and will be sunk without any
further delay to a depth of 300 feet. 1t will.
probably onnect with the main Il vel Or more
properly tunnel, and will likely strike the
ledge at a depth of 10 feet. The development,
in this shaft will be watched with keen inter.
est, as it is expected to show the east end Of
the Rainbow lode to be fully as rich and ex.
tensive as that part comprised within the Al
ice boundaries. In thise event there will be 6
demonstrated length and richness to the Rain
bow lode Of several thousand feet, and if the
value of the ore and the strength of the
ledge should remain unchanged, it will be
impossible to conceive the vast amount of ore
which will be yielded within the next twenty
years.
