what is Being Bone in and About
This Property.
A SENTINEL reporter, in company with
Gen. Conner, visited the Eureka Tunnel
on Sunday, and was shown through the
mine by Foreman Maxwell. There were a
number of improvements noticeable,
among which was the progress being made
in the erection OF the new hosting ma
chinery. The engine at the mouth of the
Tunnel is in place. and pipes are being
laid to carry steam to a point 1925 feet
from the entrance, where the hosting
works are fairly under way. A large
chamber has been cut out 40 feet south
of the Tunnel line, which contains a
double compartment shaft, AIS, over
which a substantial gallows frame has
been built. The shaft is down rs feet, but
will be sunk an additional so feet to con-
machinery is started. Some fine streaks
of ore were encountered in sinking the
shaft, which will in due time be prospect
ed. One Of these seams is three feet
wide, and gives assays as high as S100 per
ton, with a large percentage OF gold, and
carrying some manganese.
'LUKE's DRIFT"
To designate the various workings they
are named after some Of the men en-
ployed in them, generally the miner who
works at the breast. When the hosting
machinery is started regular levels will be
established. All the principal work is now
being done from 100 to 1875 feet below the
Tunnel level, and most Of it south Of the
Tunnel line. The Foreman led the way
to the south drift, 115 feet below the Tun-
mel level, and started from near the old in
cline, or 'dear little winze," where ore
was first struck. The drift has been run
800 feet on a vein from 8 inches to 6 feet
in width, the ore being c%arbonates,
yielding very handsome returns, as
says ranging from 500 to $3.50, and show
ing good percentage Of gold.
Much low grade ore was broken
down in running the drift, but
this was slowed away for future use.
None assaying less than $50 has been taken
out. The bottom Of the drift, for almost
the entire distance, Mr.. Maxwell said, was
in good ore, and can be extracted at any
time when better hosting facilities are
available. The plan of the company was,
| said Mr.. Maxwell, to drive the drift as ex-
peditiously as possible and at the least
| possible expense. Work has been tempo
| rarily stopped in the breast Of the drift,
| although 1t shows better than at any point
| along its course. The ore seam appears to
be spreading out. Several limestone
boulders have been encountered, not I'M
| like the p~orphyry "horses" on the Com
stock, but these are surrounded by veins
| Of rich ore. Considerable clay is here
found, which carries ore that
! assays $3.50 per ton, principally gold.
| Some small seams have been followed
across the drift near the face which are
found to be very rich in carbonates. This
is sacked and sent to the surface, though
it requires q large amount of tedious
handling. Further work here may I'M
cover something valuable. as the vein
widens out to nearly 10 feet, most OF 1t
being fine ore.
THE ADDISON DRIFT.
This Ia the point where the strike during
the past week was made, and is no doubt
the most important ever made in the mine.
It was made in following a small vein from
the south drift, and is about 60 feet u
of the tunnel line. The character OF the
ore here encountered is what is termed
stedefeldite, composed Of %sulphurets,
black metal and carbonate, with here and
there a stain of copper. A large stneak
of black metal rum through it, similar IN
appearance to that first struck in the winze
from the tunnel level south drift. Assays
made from selected specimens run as high
as So, 900 to the ton. Quite a little cham.
Der has been dug out, yielding aDout
40 tons. which is kept separate from tne
other ores. A shipment of this was made
to the Eureka Con. furnaces on SUNDAY,

with this strike is that it is near the center
