+. L. Torres, of the Eureka-Croe-
sus. who is on trip Of inspection of
the property, stated to the Sentinel
that he is well pleased with the work
that has been done since his last
visit.
It II the Intention of the company
to start at once the sinking Of the
shaft to the 500 foot station. from
which levels will be run underneath
the ore deposits now opened on and
below the 400 level. Later on. levels
win be driven at points between
these stations. Much other explora-
tory work Ii planned, and win be
taken up as soon - arrangements can
be made to do %.
EUREKA-HOLLY
Work on the 600-foot level OF the
Holly mine has been hampered by
poor air and Q raise II now being
driven to the 500 level-to afford nat
ural ventilation. This raise IL being
driven along the porphyry-limestone
contact at q point near whore the
high grade ore was recently cut on
the 600 level. This raise will pros
pect important territory along this
contact and beneath known ore ON
the 500 level. Development IL being
continued on ore on the 400 and 500
levels and high grade ore being ex-
tracted for shipment.
BULLWHACKER
1t Is reported that the cleaning Of
the old workings on the bottom level
of the Bullwhacker mine will be COM
pleted next week. That company will
then commence active development
on that level. both on ore showing In
the old workings and by cross-cut-
ting to pick up the downward extern
sion of ore bodies worked on higher
levels in early days. The manage
ment expects to begin shipment of
high grade ore in short time.
REPORTS PURCHASE OF
PORTION OF HAMBURG MINE
A correspondent writing to the
Reno Journal from Eureka. under
date of May %. says:
Some time ago the Eureka Uncle
Sam bought about one-third Of the
old Hamburg mine, which endlines on
the south Of the Uncle Sam. and
from which large quantity Of very
rich ore was produced during the
early days when Eureka was the
bright spot In Nevada ore production.
>All work on the Uncde Sam has been
With the end in view of opening up
this portion Of the mine and break
ing into the Hamburg ground. It has
been for some time the opinion Of
Frank T. Torpey that large body of
commercial ore will be opened in this
section Of the property.
In this matter his opinion is backed
up by that OF l.. ]. Rosenshine who
recently made an examination of the
property. Engineer Rosenshine has
had much experience IL mining. not
only In the United States. but in Peru
and other South American countries.
Sam Mr.. Rosenshine says in part:
1.-THE property is located on Prospect
mountain and lies between the Helen
Mortimer property and the Hamburg
mine. The ore zone on which the
-Croesus Mining Company is
working and the ore zone from the
Helen Mortimer. pass through the
Uncle Sam property. All the large
mines In the Prospect mountain dis
trict have been formed at the inter-
section Of two or more ore xones. The
ore occurs in ore zones where they
have been cut by cross breaks. The
mineralized solutions probably flowed
up through these cross breaks form
ing ore bodies by replacing limestone.
From surface indications the part Of
the property where the largest ore
bodies should occur is in the south
ern portion Of the Uncle Sam claim,
where the two ore zones appear to
come together. At this part OF the
property are also visible on the sur
face q number Of cross breaks and
dikes one, Of which contains ore."
Since this report was made the
driving of the south tunnel has pro-
gressed with renewed activity. Super

careful survey OF the property to de-
