MINING MENTION.

greater part of that coming out will
be good concentrating product
MIR. Hanchett said that the tunnel
had passed through the vein The dis
tance between walls is fully twelve
feet, but the mineral only shows on
each wall with gangue between. The
drift on this vein will be started as
soon as the heading of the tunnel has
reached the distance of about 100 feet.
1t Is believed by some mining men that
the Tropic and Seaton veins come to-
gether before reaching the tunnel, and
that it is because of this that the large
bodies of ore are disclosed at depth
of more than LOO feet If this proves
to be true the Seaton vein. being the
older location. will take most of the
territory on the west OF the tunnel, but
the Tropic will take all of that to the
east of the tunnel because of the fact
that there We're no Seaton locations on
the east of the line. This strike Is of
great Importance to the tunnel people.
for II proves what they contended
when the tunnel was started-that is.
that ore bodies will be found at great
depth. This is the deepest point at
which any vein in this county has been
touched, and goes to show that deep
mining in Clear Creek will pay. The
of higher grade product, and it is
believed that shoots of smelling ore
will be found on both sides of the tun-
mel.
Manager ]. j. May said tonight that
his company will be ready to begin
work on the west side of the tunnel as
soon as the Newhouse people give their
consent. Mr.. Noyes. manager for the
Tropic and other properties belonging
to Jay Morton, the Chicago million
aire has investigated the showing in
the tunnel. and finds the drift to be al
most Identical to that in the TrOpic
workings. and for that reason is under
the impression that his people may
also work the vein in their own terri
tory.
Ihe reports are current that not
alone will this vein be worked, but
plans are on foot for the working of
many others which have already been
cut. and while not so promising MS the
one of to-day. some drifting may open
into n larger deposit of mineral
The Newhouse people have been put
ting in air pipes so that these drifts
can be commenced. The blower at the
tunnel is the largest mine blower in
the United States, and is identical to
that used by the smelters. 1t has II
capacity for handling siXty-three cubic
feet of air per revolution. and with
from 200 to Do revolutions per minute.
The pipe running from the blower into
the tunnel is twentyfour inches in di-
ameter. but is reduced to nineteen
inches. and this has been carried up to
near the breast of the tunnel. and will
probably be the size for the distance
to Central City. The blower is used
both for blowing and exhausting pur-
poses.
Coming with this discovery it has
just leaked ont that the Chesapeake
tunnel at Yankee Hill made n strike
early last month. BY the working of
air drills in this mineral body n dis
tance of 125 feet has been gained in
1t, and there is no sign of n pinch but
rather improvement with every shot
The vein is a blind one, nothing being
known of 1t along the surface. 1t lies
at almost right angles with the tunnel
line. The pay streak has widened from
two to four feet and values seem to be
increasing. The edge of the ore shoot
ran but ST. ton: as n whole il runs
$50 n ton to-day. 1t is now intended to
keep the tunnel on this vein for n short
distance. when IL vein that lies almost
parallel with the tunnel will be cut.
after which the tunnel will follow it,
This changes the direct course of the
ates doing the same work at II later
period.
