Another shipment of four cars of
ore was completed to-day. and the
bins at the mine are holding more
than this quantity for next weeks
shipments. From the amount Of ore
now on the surface, and broken un-
derground, three weeks work for the
teams that are hauling from the mine
to the railway station is assured. with
the ore bodies from which the high
grade is being extracted continuing
to show as strong as ever.
The "Shale raise" that was started
last Summer from a drift running
from the 400 foot level to the contact
OF the Hamburg limestone and Ham
burg shale on the Dunderberg claim.
is about $50 feet above this level, and
has found several masses OF fine ore
either along the contact or in the
limestone adjacent. There is yet
considerable distance above the top
CT the raise TO be explored before the
old slopes are reached, and drifts
both north and south along the con-
tact will open new ground. The con-
tact of the shale and limestone is
nearly vertical, the sedimentary rocks
in this portion of the district having
been turned at an angle of about 30
degrees at the time the Eureka noun
tains were formed. Short, horizontal,
slips occur frequently and 1t is along
these that some OF the best ore bodies
are found. At the top of the shale
raise yesterday an ore body IL feet
long and feet high was showing, all
of which will go better than so dol
lars per ton. A drift will be run
north along the contact at this point
to connect with the old workings and
insure plenty Of air for further de-
velopment. Number winze is now
down 80 feet, with drifts north and
south at 20 feet In depth, correspond
ing to 470 feet In the main shaft.
The fissure on which this winze was
sunk is called the North-South fis-
sure. and is the main fault In the
Croesus property. Good ore is be-
ing taken out in the north drift from
this winze. while the south drift Is in
exceilently minerahzed limestone. and
may find ore at any time.
The high gold contents In { h
Croesus ore are even q little better
at the deepest points reached than
they were above. For the first eleven
months of 1920, the total shipments
OF ore from this mine averaged 1.44
ounces in gold, or s29.71 per ton.
Silver contents are also holding as
high as ever, and the precious metals
recovered are making up largely for
the loss incurred in the lower prices
for the lead In the ore.

The cutting of the station at the
500-foot level has been completed,
and the sinking of the main shaft
continues. It is now some 35 feet
below the 500. The shipments of
high grade ore to the Utah smelters
continue.
The new mill building is now en-
closed and the carpenter force is en-
gagged in putting in the windows.
doors and partitions. 1t is expected
the mill will be completed and ready
for operation by January Is next.

Salt Lake Tribune: Word was re-
ceived Tuesday by A. G. Burritt. To-
cal mining engineer, from G. A.
Fletcher, superintendent Of the Eu-
reka-Nevada mine, near the town OF
the same name. that a nice streak OF
galena ore had been exposed in the
face of the lower tunnel about $50
feet from the portal. This strike Is
the most important development. ac-
cording to officials of the company.
since the lower adit was begun to tap
at depth large bodies of ore exposed
in the upper workings. Work was
begun on the lower tunnel about a
year ago, when the company became
convinced that the cheapest way to
handle the ore developed in the up
per workings would be to drive an
adit from the side of the hill oppo-
site to that on which was situated the
portal of the tunnel driven for ex-
ploration purposes. BY driving OF
the new tunnel a long and expensive
wagon haul to the railroad will be
eliminated. When the new tunnel
has been connected up with the ore
opened up in the upper workings the
