fsst Work was begun ON this tun-
nal about q year ago. when the COM
many became convinced that the
cheapest way to handle the ore de-
vsloped in the upper workings would
be to drive an adit from the side Of
the hill opposite to that on which was
situated the portal Of the drift driven
for exploration purposes. In this
tunnel about 1876 feet above the level
Of the main working adit. several
chutes of excellent ore were opened
up. As all of these chutes seemed to
Be making down, the company de-
eided to drive the lower tunnel. Not
only will the ore be developed at q
greater depth. but a long and expen-
sive haul over the hill will be elm
mated. The portal Of the lower tun-
mel Is but three miles from the rail-
road loading station.
EUREKA-HOLLY
The discovery OF high grade ore on
the 400 foot level reported last week
has now widened out to four feet.
and Is Of as good quality as ever came
out Of the Holly.
On the 500 foot level the develop
msnt work being carried on is very
satisfactory and some naturalization
10 beginning to show.
Road conditions have prevented
ore shipments during the past week.
The crusher and ball mill parts Of
the new mill plant are now being
given tryout runs.
UNCLE SAM CONS.
The Eureka Uncle Sam Con. Min
ing Company has increased its force
this week and the main tunnel Is now
being driven three feet a day. A
calderwood drilling machine has been
ordered and will be put In operation
In about ten days. when It Is expect
Cd the footage will be increased one
third with the same force. Superin-
tendent States says the face Of the
tunnel is now one solid mass of
quartz. showing more naturalization
than at any time.
