MODERN EQUIPMENT
FOR EUREKA MINE
COMPANY INSTALLING ELECTRIC
COMPRESSOR AND WILL BREAK
BIG BLOCK OF GROUND WITH
MACHINE DRILLS - TONS AND
TONS OF ORE READY FOR THE
MILL AND SHELTER.

While tramping the hills, our mine
reporter was attracted with the re-
newed activity apparent at the Eur
eka mine, in Prosser gulch. This prop.
erty has been semi-dormant for some
time past, due to the adjustment OF
the affairs of the company. Arrange
ments have finally been completed
for steady operation, looking to a
heavy output and profitable returns.
Contractor Peck, with force of
men. is busy enlarging the shaft
pressor that is on the ground ready
for installation. A pipe line connect
ing with all underground workings
is in place ready to connect UP with
the compressor. This compressor is
a compound, electrically driven, and
has a capacity of four piston mach
ines.
Supt. Bray called our attention to
the large block of ore in the 600-foot
level ready for the mill, just as soon
as the present top equipmsnt is COM
pleted. This ore appears to be at
least six feet in width and extends
for distance of 24O feet, the value
of same on conservative estimate
is said to be from $500 to $1,000 a
ton. There is solid body of ground
above these workings for a distance
of 145 feet ready for Stopping just as
soon as the compressor is in place.
Figured on a conservative basis OF
but five dollars per ton saving in
the present mill of the company,
which is fully equipped to care for
the Eureka output. there is no less
than sS0.000.0O of profit available for
company dividends in sight in this
one block of ground.
The shaft, which is 700 feet in
depth, is equipped with pumping ap-
paratus to care for the water that
accumulates through surface drainage
a fifty horse power motor is to be
put in place to run the new Clayton
compressor. The local management

feet to block out new ground for

reputation as a producer of the yel-
low metal in large quantities. In the
early days this mine was one of the
gold producers that made Prosser
gulch famous. The surface workings
of this property to the oxidized zone
proves this statement. The large ore
body in the 600-foot level is but a
small part of the tonnage that will
be available in short time, with
quick modern methods. Heretofore all
work was done by hand drilling,
while with the new compressor equip
ment one drill will accomplish the
work of seven men in the same
length of time. The breast of the
Newhouse tunnel is just below the
Eureka mine workings, but at q
depth of some 1900 feet A thousand
feet of virgin ground remains to be
exploited between the present depth
of the Eureka shaft and the present
tunnel workings. 1t is fair to assume
that the present values will continue
with depth, as proved by adjoining
mining properties, so that the one
ore shoot mentioned above can be
credited with at least ten times the
amount OF profit available in the
block Of ground exposed above the
600-foot level.
With machine drills in operation.
the shaft will be sunk further
depth of 300 feet, Mt which point 1t
is predicted that the Rara Avis vein
makes a junction with the Eureka.
The Rara Avis vein Is large and is
rich in gold values. The coming to-
gether OF these veins should make
a body of ore equal in size and rich
ness to any of the old-time bonan-
Zas.
The Eureka mill Is fully equipped
with modern milling machinery, up
to-date In every respect. for the econ
omical treatment OF the ores of the
mine.
The future of the Gilpin- Eureka
company is an assured success, now
that modern labor saving devices are
being installed.
