Utah COPPER HAS
SPLENDID FUTURE

Enormous Ore Tonnage in
Bingham Mine.

Property Is Largest -Grade
Porphyry Proposition in
United States.

Trippe, Thompson G. Co. have issed
statement in regard to the Utah Cop
per company which is timely and of
much interest to all the state. The
stock, says the report, may be CON
sidered one OF the safest investments,
rs the possibility Of increasing the ca
paclty Of the concentrating plant makes
1t particlarly attractive proposition.
The report says that the properties at
Bingham contain the following re
serves:
total of 100 100000 tons Of ore,
65,OOO,O00 tons Of which average . per
cent copper, From this particular ore,
] ,3OO,000,000 pounds of copper will be
recovered, the net value Of same count.
ing on a II | o cent metal market and
cost of production of $ cents per
pound, amounting TO SS5,s00,000. The
balance of the tonnage, or 55,000O0O
tons of ore, averages 1,5 per cent cop
per, in which there are $40, 100000
pounds of copper. On this tonnage,
counting on - 1-2 cent metal mar
ket and cost of 10 cents per pound
for production. the net value is So 900
600, giving the combined reserves of
l20.OOO,O0O tons or ore n net valua-
tion Of S1lS,700,00O The report IN
part says:
The Utah Copper company's proper
" is the largest Of the low grade por,
phyry producers in the United States,
The mino is situated in Bingham Can
yon, twenty-cIght miles southwest Of
salt Lake City. the Coppertou mill of
500 tons daily capacity, short distance
below the mine, and the Garfield mill
of 5000 tons capacity, at Garfield, on
salt lake, twenty-siX miles distant from
the mine
The mine is comparatively new one.
having been producing copper only
since June, 1907, and with the enor-
nous amount of ore in reserve has be-
fore 1t brilliant future. The property
belongs to that new class of deposits
which seem destined to play such an i'm
portant role in the world S copper pro-
duction. The amount Of ore. averaging
approximately per cent, in reserve
at this property is so enormous that a
the present rate of production there Is
sufficient TO last twcnty-seven years,
and in addition there is probably an
equal tonnage. Of 1.5 per cent copper
ore. Unlike the average copper mine
the ore bodies here are not worked by
the underground method, with deep
shafts necesstating high hoisting and
pumping expenses, but almost entirely
by huge steam shovels which mine and
load the ore directly into railroad ears
IN one operation The property is
equipped with ten of these machines
and the number is being continually in
creased, as the management expects
soon to abandon the underground meth
od and work all the ore by steam
shovel
During the past year the developed
and partially developed area has been
increased by eight acres, making a total
of eighty acres. There was at the end
of the year in the fully developed, par
TALLY developed and reasonably assured
reserves, tonnage of S0,000,00O tons,
of which 65,O00,O00 average = per cent
copper and 15,000,00o run approximate
~ ID per cent copper. In addition to
the above it is estimated that there
are 40,000,000 tons of l.5 per cent cop.
per ore Indicated by drilling,
It is gratifying TO note that this
property, which has years Of ore sup
ply exposed and awaiting treatment has
added 100000 tons to its reserves dur
ing the past year, and is continuing its
exploratory work.
The company operates two concen-
traitors, the Copperton and Garfield
plants. The former is treating 800 tons
of ore daily and the latter 5000 tons,
or "A combined production of $500 tons
day, about one-ffth of which, assay
ing 2 per cent copper, is being taken
from the underground slopes and the
remainder, assaying l,T5 per cent cop
per from pits by steam shovel,
The results for the various quarters
since June, 1907, are as follows;
