/ obtain sufficient ventilation TO begin
the work of raising the three.com
partment shaft, the distance between
the bottom of the shaft and the
crosscut being about 450 feet. A con-
tract will soon be let to do this drill
ing and work will be started in a very
short time. The formation being
favorable, it is estimated that it will
not require more than a month after
drilling begins TO make the coveted
connection, when the work of raising a
three-compartment shaft from the
erosscut TO the bottom of the old shaft
and widening out the shaft to three
compartments will be pushed as fast
as possible, as it is realized that wnen
this work has been completed it viii
materially lessen the cost OF minine,
owing to the much closer proximity o.
the large ore bodies to the new shaft
than to the one being used at present.
This work will require a long time and
IA considerable outlay of money TO com
plete, but it will mean a great saving
in the end. 1t is quite likely that the
new shaft will be continued TO much
greater depth han the l000-foot level,
as the ore bodies nave already been
proven to the ll00-foot level, and SHOW
strong in the bottom of the workings
on that level. During the week a great
improvement has taken place in the
vein being developed by the east
drift from the bottom of the 1000
winze. which corresponds with the
1100-foot level. The face of this drift
exposes four feet of very good ore at
present, against two feet of much
poorer rock last week. This drift is
no doubt etnering the big ore shoot
exposed by the drift above, from the
125-foot point in the Wine, and which
was proven to be fully eight feet wide
for a distance Of owe 60 feet. A good
showing has also been made in the east

There is but little to report from,
this company's property this week.
Pending the erection of the new 80
stamp mill, the underground work viii
be very light, as everything is in shape
with that point in view having been
carried on for the past eight or nine
months. The details of the mill are
fast being put into shape, and as sooa
as one or two contracts, which nave
been agreed to, have been signed
ground will be broken. The signing of
these contracts has been unavoidably
delayed, but they will no doubt be sign
ed within the next 10 days. The work
now going on underground is being
confined to the 400-foot level, where
some good looking stringers ana
lunches of ore are being followed by
the south crosscut. The raise from the
T0-foot level, having made connection
with the Wine from the 60O-foot lever,
work has been discontinued on that
level for the present, the object OF Sc
curing a better circulation OF air aV-
ing been accomplished.

stringers and punches of ore. A short
