Yesterday at noon, the main compartment
shaft at the Moulton mine had been dropped
to the depth of over BOG feet. This shaft is a
model piece of mining mechanism, and it is
so heavily timbered that it will last long af-
ter the present generation of people have
pas out of existence. and it is intended to
be used when the mine is worked to a depth
of 5000 or 1000 feet. The shaft is making
fair Roadway downward, and no trouble is
experienced from foul air in the bottom since
the large airpipe was run down the shaft.
The granite rock through which the shaft is
being sunk is moderately hard, but not as
tough blasting as it was last week. The SUI
perintendent hopes within two weeks, to have
the Ingersoli drills, driven by compressed air,
at work in the shaft, when sinking will be,
compared with the present speed, very rapidly
accomplished. Thee eight-hour shifts are
engaged IN dropping the shaft down. AT the
200-foOt level the cross cut which is being
driven to the south to tap the ledge is in
fully twenty-eight feet. The rock through
which it is passing is alternately hard and
soft granite with small seams Of quartz. LII
the face OF the cross-cut yesterday there was
indications of striking vein matter, but the
end of the DRIFT, which is seven by five feet
in size, is, by calcutiOn, quite a distance yet
from the north vein of the Moulton. 1t is
expected the north vein will be reached and
tapped inside of fifty feet more.
The discovery in digging the foundation
for the 40 stamp Moulton mill Of a new and
large vein of ore, hitherto unknown, will add
immensely to the importance of this mining
property. This new vein, as far as opened
with a prospect shaft about Is feet deep, is a
bonanza in itself, the value of which cannot
be estimated at present. In width the vein
matter, composed Of high and low grade ore,
is about twenty feet in thickness. OF this
ore-vein five feet next to the foot wall Is rich,
tirst-class ore. Five assays made from the ore
taken from this part of the VEN, resulted in
showing the ore to be worth 5000. OS per ton,
Most of the balance of the ore of this vein
assays sufficiently well to be dividend-payin
rock when put through the mill. THIS new
vein runs parallel with the main Moultor

beyond a doubt, a distinct and strong lode
independent Of any other, with an incline To
the north.
The condition Of the great Alice mine il
excellent, especially at the 10O-foot workings
, which are showing better as the work o
i opening progresses. The ore coming from

body is presenting a fine appearance. Tn
