Development work in the Eureka
Croesus properties continues to yield
most satisfactory results, not only in
the general persistence of the aver
age grade ore bodies, but In the fre-
quent occurrence of high grade ma
terial, which is being found In all
directions. Explorations both by
sinking and drifting are constantly
adding to the mines reserves, and en-
tending the known boundaries of the
ore bearing formation.
Superintendent julius Huebner,
in speaking Of the progress Of opera
tions during the month said:
The connection to the old Dundef-
berg stope is showing up we'll as the

self is ore Of fair grade running $23
In gold. silver and lead. 1t gives one
a pretty fair impression of the ore
values from this mine in the old
days. when the waste used for stope
filling Is found to be worth $23, and
also gives line on what may be ex-
pected in returns from a continuation
of this ore body when we reach It
through the work now going on
Some high grade chunks of the old
ore are being sorted out of the old
filing as the stope is emptied.
THE ore body in the face of the
400-foot level is about six feet wide
and of good shipping grade. At
present only one shift Is at work IN
this drift, but as soon as air connecS
tions are completed, / will put two,
and quite probably three shifts to
driving it, so as to speed up the de-
velopment of this level.
I'm the Cave winze on the 200-foot
level the ore maintains its strong ap-
pearance, while the open cave is still
present above the high grade mater
ial There is also a good showing of
lower grade ore here, that runs
around $40, and will be added to the
reserves of milling ore.
I'm Jinksville the drift is being
run along the north-south fissure, be-
ing spotted throughout with lead
silver ore Of extremely good value.
"The driving of the drift on this
fissure is going ahead rapidly, and

reached directly under the old.
Atlas shaft. When we get there,
a raise will be made to the workings
of this claim, where good ore bodies
are known to have been developed
when the property closed down many
years ago.
"One of the finest ore showings
ever found in the Croesus properties
can be seen in the north drift. on a
crosscut that was run to tap the por-
phyry. Here there is ore from one
foot to four feet thick that is carry
ing exceedingly high values. Assays
from this body run at times " oun-
ces gold, 500 ounces Of silver. and 60
per cent lead. While these returns
are from the best looking material
all of the ore is of real bonanza char
acter. An interesting thing in con-
nection with this ore body is that the
porphyry itself carries an average
value of SIT per ton.
Yesterday we started shipping an
accumulation of high grade ore that
has been taken out in the course of
development work. This ore has been
sampled and sacked, and there is a
large quantity of it that runs away
up in silver content. The average
value per ton of the shipment is over
S4OO. We will also start shipments
next Monday of ore in bulk, which
road conditions and other troubles
have been holding up for the past
week or So"
