state TO do this the company had to
overcome a great many obstacles.
The first unit of the first half of tho
mill was set in action a year ago last
November. The second unit ,complet-
ing the half section, followed in March,
1910. At the time the section was
started the weather was extremely cold
and Supt. William A. Kidney encoun-
tered extreme difficulties in starting up
the mill in the winter time. AS tho
warm weather began TO come the ma
chinery became more nimblc until the
kinks were taken out and it moved
like clockwork.
AS originally designed the mill was to
b. of four separately operated units or
II capacity of 800 tons each. A provi-
sion was also made for the doubling OF
this capacity by adding four more
units. 1t was expected that this would
give n mill of 1000 tons a day
The half section now running has
outdonc all expectations. The units
have been found capable of almost
twice what they were originally de-
signed for. Tho two units We're first In
creased to 1000 tons a day. At present
the average Is about LOO tons a day.
through an average of 500 tons day.
General Manager Alfred Frank Is GER
tain that with some changes that arc
contemplated. the capacity of each unit
will be brought up to 1000 tons day,
making the plant carry just twice what
it was originally designed for.
When tho Ohio Copper issued its first
statement declaring that the cost OF
mining by the cnving system would DO
20 cents Il ton and tho cost of milling
the ore would be 80 cents n ton. there
We're many that seriously doubted the
has demonstrated that this is far in
excess of what the actual costs have
turned out to be.
MAKE FINE SHOWING
a glance al the cost sheets OF the
company would quickly convince one
that the system OF mining used by the
company Is about as cheap as possible
in extracting ore from ~ vein. BY the
caving system the cost to the Ohio
Copper has averaged around 81 cents Il
ton for the entire year. For September
the average cost was BIS cents. during
October 3l.3 cents while in August it
was 277 cents II ton. This chcapcning
OF mining cuts the estimated cost in
half with some to spare.
The milling problem under Mr.. KID
ney has also received q big cut Dur
ing the Sehr II mas Averaged AROUND
81 and 80 cents. which included office
rent. superintendency and everything
outside Of transportation. The mill re-
covcry on ore running from 1.3 por cent
copper to Ia per cent, has been from
60 to 65 per cent. This Is being gradu-
ally improved,
During the year developments ut the
mine have continued, the levels have
been extended out and everything
brought up to good standard for
economic mining The minc Is now in
shape so that almost double the tom
mage could be handled with a days no.

HANDLES BIG TONNAGE.
The Ohio IS now mining and mill
| ing on an average about 4I,010 tons o.
! ore II month. During the year nbou;
| 900 tons of ore were put through
| the mill. At the mill about 60 men
| are employed, while on mill CONSTR,

| Of employees shows $50 men. With Ga
exception Of the men on construction

unit would probably be equipped With

With the present tonnage that Is

the mill in operation there is no doubt

| produced more than doubled.
| ORE RESERVES.
1t Is estimated that the ore reserves
in the developed part OF the Ohio Cop
per mine are 100000 tons. With the
