OF OPENINGS.


men at work underground where The
various connections between the eX'
traction rooms and haulage drifts arc
being made Altogether, only m
amount of work averaging 265 feet
weekly is being done. This consists
Of driving six drifts and putting up
nine raises. All the work is confined
10 the 42O-foot level two are being
advanced on the S7O-foot level and the
remaining three drifts are being ex-
tended along the main har;dge level
which is i20 feet from the surface.
Two raises being put up to the stock
pile at shaft No are now nearly
completed seven other raises, when
finished. win be used as ore chutes are
being put up from the 420-foot level.
Much of the work is being done in the
vicinity of shaft No. ?. where ore eN-
traction from the mine Will probably
be commenced. one drift is being driv-
en- into the Captain claim lying beyond
this shaft for the purpose of establish
ing an ore pocket there
The stock pile at shaft No. con-
tains 100000 tons of low grade dissem-
mated ore which has been removed
from the mine i'm the course of the
stupenduous mining operations attend
ant upon blocking out md making the
workings ready for production. When
the big mill begins treating 1000 tons
of ore daily about January 1, 1911
this stock pile will furnish the product
until il is exhausted. Although the
concentration naturally, Will begin
operating with an intake of about
1000 tons daily. this supply will be
gradually increased to 1000 tons every
twenty-four hours.
The total amount Of work done un-
der ground at the Miami mine, includ-
ing shaft work. drifting and raising
has reached the notable figure Of $4,000
feet, or considerably over IA miles. |
This footage shows clearly at
what rapid rate the Miami Copper
company has carried on its work of
making mine during the past three
years. IL will be remembered also |
that the total underground work COM !
pleted early last fan was about eight |
miles. that the workings have been eX- /
tended about six miles within the past |
year The underground work is divided |
into 10000 feet of drifts. and raises
and 2,OG2 feet of shaft work. The un-
foreground workings underlie wholly
or in part the 81. Johns Nos. l and >, !
the Red Rock Agent, Captain, st
Johns, Fraction, Red Springs and
Climax claims.
The churn drills, three in number.
continue To prospect around the outer
edges of the ore body. thus giving in
formation leading to a knowledge Of
it's definite outlines. The average depth
of the holes put down is approximately
$50 feet and the best record made in
drilling has been As feet during each
shift Of twelve hours daily for an en-
tire week.
The construction work has reached
such an advanced stage that there is
every reason to believe that the treat
ment of ore can be commenced by
January 1. 1911. At the concentration
virtually the only work of importance
TO the finished is to complete the in
stallation Of machinery and also the
facilities for handling the concentra-
ties and tailngs as they come from the
mill The pumping station Of course,
Is not yet done. as the work Of laying
the foundations for it has only re-
Gently been commenced. The pump
station will raise the water from
Miami Flat 10 the storage tank near
the concentration and il is located
about two miles from the mill i'm a Il
bee-line. The pumps will bc driven by Il
electricity, and a power line from the
companys large power house az the /
city OF Miami to the pump station has
already been completed. The pump |
station should be ready for use by
December LIST. It's actuating equip
ment will consist Of a 4OO-horsepower
motor
The $4,000 foot pipe line which will
convey the water to supply the con-
centrator from the old Dominion mine
is nearly done, but is not yet fully
connected up in readiness for use. The
company. according 20 the present
plans, will use about 100000 gallons
n day Of Old Dominion water and viii
have a large auxiliary supply from its
own wells on Mama Flat I'm the vicin-
ity OF the pump station whore churn
drilling has been carried in for some
time in a successful effort TO locate an
underground current.
The company will have an elaborate
system Of settling apparatus and by
means Of this. will be enabled to use
the same water over and over again
for concentration purposes. Thorough
plans reaching over an experience Of
many years have been laid to obviate
any future difficulty as TO disposal Of
tailings from the huge mill For the
present Red Springs gulch directly
east Of the concentration viii be
storage place for the tailngs and a
dam thrown across the faat OF the
Fulch will make n reservoir In which
the water may be impounded. The
