Before taking over these proper
ties and deciding upon their develop
ment upon the basis necessary te
successfully handle such a PROPOSE
ton the American Zinc company had
it's engineers upon the property for
a couple of years thoroughly inves-
tigating its ore deposits. These en-
gineers were engaged during this
time in drilling a large number OF
test holes at various places on the
property. These holes were driven
with churn drill to depths varying
from 800 to 400 feet and samples
of the borings were taken at every
five foot depth and sent away for
assay. In addition to this surface
work the company kept small num-
on the ore bodies.
One of the first tasks to be I'M
dertaken by the mining company was
the construction of tramWay from
the foot of the hill to the upper end
of the mill site on the top of the hill,
which is between 600 and 700 feet
above the valley This tramway is
1900 feet in length with a maximum
grade of 81 per cent and an average
grade of % per cent. Over this,
tram cars are operated by means of
wire cables, the hoist being rated at
so horsepower for which the power
is furnished by 70 horsepower
steam plant. The latter is tenn
porary power plant and is about to
be replaced by an electric hoist with
capacity of about SO horsepower.
This tram is at present utilized
only for the lifting of building ma
terials and machinery for the mill
and supplies for the mine but it will
later be permanent feature of the
mine and mill and will be enclosed
from top to bottom by snow shed.
Mill Operated by Electricity
The mill, the upper section of
which is on level with the mine
opening about a quarter of mile
will be very large timber
structure extending for quite dis
lance down the hill. All of the con-
crete foundations for this mill have
been completed and the concrete
floors poured. The frames of the
TWO lower sections have been finish |

S the expectation of the superinten-
lent of construction, Harvey Ma
hews of Denver, that the mill will
,e completed about January Is.
Water, of which large quantities
will be required for the operation of
his mill, will be taken from Car
ENTER creek and will be lifted about
90 feet through main starting at
inches at the bottom and reducing
0 four inches at the top. This will
e elevated by pump having ca
acity of 200 gallons minute. The
team boiler at present used in the
hoist will be moved to the
ottom of the hill and will be utilized
4 producing steam for heating the
uildings and the mill, four-inch
team pipe being laid in the same
rench that will carry the water II
lain up the hill. A filter plant will /,
lso be installed at the creek.
An immense amount of modern :

ted by electricity, will be installed
