The report issued by tho Utah Copper
company for the third quarter of 1910
| shows that the curtaiment Of produc-
ton has been quite marked in August
| and September. and that In the han
ding of low grade ore the company Is
making a remarkable swing. The re-
port or the company. signed BY c. NJ
MaeNeill. president, d. c. Jackling,
general manager. is as follows:
During the mont, Of July I'LL three
of the concentrating plants were in
operation. at the end of July tho Cop.
perton plant was closed down pcrn,a-
nently, and therefore for the months
of August and September this report
covers the operations of the Magma
aud Arthur plants only The Copperton.
plant was closed In conformity with the
decision Of the directors that the entire
output of the property could he more
economically and probably handled in
the larger mills near Garfield. and that
therefore 1t would be to the best oper-
ating interests to disnantlc the Cop
pcrton plant and use the machinery III
y
and Improvement Of the Arthur plant,
and as the new material for enlarge
.ment of 1t has recently commenced to
arrive, a portion of this mill has been
closed for remodeling purposes. 1t Will
be near the end of the year before any
portion of the Arthur plant can be put
in operation In its remodecd form. In
the meantime its capacity will be re-
duced about one-th.rd. but when the
alterations are completed its capacity
will be more than doubled
The Improvement of the Magma
plant Is practically complete and that
plant now has IL normal capacity In
excess of 10000 tons per day. The
relative proportions of tonnage treated
at the Magma and Arthur mills during
the months of August and September
after the ore formerly milled at the.
) Copperton had been diverted to them.
was approximately rs per cent at the
Magma and Is per cent at the Arthur.
At present, the proportion being treat
( cd at the Magma is higher than this.
due to n portion of the Arthur plant
being closed down for alterations.
