approaching the time when it will be-
come producer-and q valuable
one-was the conviction of a number
Of Libby men after visit to the
mine of the Glacier Silver-Lead Min
ing Company last Friday. Arriving
at the mine the visitors were taken
in charge by v. w. Weller, president
OF Tle company, and by John Johan-
son, secretary, and were taken on an
interesting trip through the under
ground workings.
Enterin the mine at the main tun
mel entrance they followed a large.
we'll constructed tunnel, lighted by
electricity, for several hundred feet,
finally picking up the ore ledge. This
ledge was then followed for a dis
tance Of 1400 feet, being clearly visi-
bic for that entire distance with tr,a
exception of a few short breaks
where the vein was cut off for short
distances. This vein is known as the
west vein and will average four to
six feet in width, with clean well de-
fined walls. 1t is white quartz, car
ryng a good percentage Of values.
Work at the face Of this tunnel is
still progressing into the mountain
with no indication Of tie termination
CT the ore.
Visit Two Ledges.
The party then crossed over
through crosscut tunnel to what il
known as tie east ledge, an entirely
different vein Of ore. This vein is
somewhat narrower than the west
one, being on an average about four
feet wide, but carries richer values
Drifting on this vein has been done
for about 600 feet with not many
breaks in that distance. This tun-
mel is also being driven farther into
the mountain.
The visitors were then taken down
a shaft to a depth of lis feet below
the two upper tunnels. The shaft fol-
lows the west vain the entire dis
tance and at the 115 foot level, or
what is designated as the intermedi-
ate level, drifting on the ledge has
again been done for distance Of
about 600 feet.
Immediately upon reaching the
lower ledge, the visitors remarked
how true is the often heard state
ment that in mining depth must be
obtained before the best ore can be
secured A big increase w the rich
ness Of the ore Is plainly visible on
the lower ledge This ledge runs about
the same width as the other veins,
and as with tie offers, there is no
Indication Of its ending. Work is
also going forward in driving into
the mountain. AT this level there is
| il vertical depth Of about 600 feet
and farther drifting Of 400 feet
will give vertical depth of about
800 feet, it is said. A raise from this
lower tunnel to the upper one is
being made on the ore and when the
visitors we're there it had gone up
about rs feet. Other raises had been
made for shorter distances, all of
| them in ore.
Veins Vary in Width.
| AS is common in such properties,
the veins vary in width, ranging in
places from three to 20 feet wide, and
in Others being from IS to 18 feet
wide. A fair average, Messrs. Weller
and Johanson said, would be from
FIVE to six feet.
Work already done has blocked oni
a large tonnage OF ore, which is be.
ing increased daily as Ihe tunnels
pre driven farther into the ore bodies
The ore carries values in gold, silver
ead ard tungsten and will provide
highgrade mill feed. The ore that Is
now being taken out is being pilee
and will be put through the mill wher
it is put into operation. Sixteen mer
are employed at the mine.
The plans of the new management
are for practically new system tt
be employed in the milling of tn,
ore, and the mill is being rebuilt will
that idea in mind. The concentrating
Of the ore values is to be done al
most entirely by flotation, and q
