Railway cars have been obtained
for ore shipments, and the bins at
the mine are now being emptied.
Four carloads we're hauled to the To-
cal railway depot this week, and six
more will be loaded next week. This
,s the first loose ore to leave In near
" a month, due to delays in securing
railway transportation. II no fur
ther troubles occur, 1t is expected
that the next 80 days shipments will
exceed any similar period in the
mines operations.
A cross cut running west, and
about 100 feet south of the face of
the 400 foot level, has found a prom
ising body of ore about 35 feet from
the main level. 1t shows to-day the
full height of the cross-cut, about 40
inches wide above the center of the
breast, and over feet wide on the
floor.
In the raise just completed to
point 60 feet above. and to the east Of
Georges chute on the 400 level,
new ore body has been found along
the shale-limestone contact, that is
yielding some fine shipping material.
both of these ore occurrences are
new, and will of themselves furnish
q good tonnage from the ore now ex-
posed, irrespective OF what may be
developed by next weeks work. The
main drift on the 400 level Is being
driven north through finely crushed
limestone, and the drift from the
bottom OF number winze Is also be-
ing extended north. Both of these
drifts are In well mineralized. crushed
limestone, and near the location of
ore bodies that were taken out in
former days from the Atlas workings.
The ore below the level OF the Eu-
reka tunnel is now exposed for a dis
lance of 100 feet IN the drift running
south from the bottom of the winze.
grees, the strike of the ore is nearly
due south, and 1t has, SO far, been
found at an almost unvarying dip.
The ore occurs on either side of a
thin tongue of rhyolite that has in
truded the crushed limestone, and is
at times abundant throughout the al |
tered rhyolite itself. 1t is principally |!
a lead carbonate and sulphate, with
more or less unaltered galena scat
tered through the mass, and the high
grade ore varies from 6 inches to 8 |
feet in width along the entire length |
Of the drift. No stopping has been |
done as yet, and the drift will be con-
tinued until the course of the ore
changes from the present dip. A
shipment last week averaged $50 per /
ION in gold and silver.
This ore body is a portion of the
'ne mined many years ago in the Eu-
reka tunnel by an association of |
Cinnamon, who extracted over $300,-l
200 worth of ore, according to the
AK records. At the south end of
heir work. fault, subsequent to the
deposition of the ore, cut the old
body at right angles. After spend
ng much time and money In en-
to relocate the ore, the
Cinnamon abandoned their lease.
For many years the property has been
die. but when purchased by the pres
INT company, was equipped with a
drills and air hoist for
below the tunnel level on
he north and south fault lines. Sink
ng a winze on a fault at the south
md of the former workings. one of
heir drifts was found at a depth of /
0 feet, and as the fault continued be-
ow. with some small ore particles
moving along the drag. the winze
vas sunk to depth of 20 feet, where
he ore body was again entered.
When the Prospect Mountain tun-
lel reaches this ground. 1t will be
$50 feet below the ore now devel-
oped, and economical mining can be
lone on all Of the material between
he two tunnels. For this reason,
work that can be done in the way of
Exploring the limestone in the vicin-
ty Of the new openings under the Eu-
reka tunnel level will be pushed
ahead; but no attempt will be made
to hoist ore other than that taken
rom the drifts or wines as develop
ment proceeds.
