Bio Garfield Concentration Is
Making An Excellent Ac-
count of Itself.
GOOD EXTRACTION RECORD
Engineer Impressed With Work Be

"That statement printed In the
News Of yesterday" said well
known mining engineer today has
Interested me very much--partlcularly
that portion OF it which refers 10 the
results accomplished at the Garfield
concentration during the months OF
May, June and July. l recall that
before the construction of the plant
began, Mill Manager BEETLES promised
To make an extraction of 6S per cent
on the Bingham porphyry ores when
the min WAS completed. only four
sections have been in operation, but
ne has made good: for / note that the
extraction for the months stated ran
from 6S5 TO 10 per cent. / also hap
pen to know that the extraction so far
this month has been very much bet
ter--thaL II has exceeded II per
cent, and may average as high as az
per cent.
II visited Garfield one day this
week and found that more units of
the mill are practically ready to go
into commission, and was told that
they would all be In operation by the
middle of September or the first of
October when Mine Manager Gates
will be ready To supply the tonnage

with now and | do not doubt that Of
ficials will be in position to give out
some interesting figures bearing ON the
cost of mining and milling, before
very long At the mine end, things
are shaping up spendidly and they
certainly could not be better at Car
field.
Mine Manager Gates / am inform
ed, is sending out better grade OF
ore than was the case q few months
ago. 1t averages about IL per cent
copper; the mill is treating In the
four units between 500 and 900 tons
of ore per day, and is making a con-
centrate product averaging from 20
to % per cent l am of the opinion
that the milling costs for August Will
not go much above 90 cents ton.
Later, az the other units are placed
i'm commission. this will be gradually
reduced. / believe Mil Manager Bet
ties expects to bring 1t down az low
as 50 cents when he gets everything
to running The fact that there are
no elevators to maintain; that from
the time the ore leaves the crushers
II makes it's way down through
the stamps and over the various ore
dressing machines by gravity, means
that the expense of handling is mere
nothing. After separation, the sands
are washed out through Iaunders TO
the tailings pond while the finishing
product goes out the lower end of
the plant in a like manner to the
concentrate bins. That is the secret
of the success Of the Boston Consoli-
dated mill. Mr., BEETLES is a master
builder in the art of mill construction
and the monument he has erected at
Garfield places him at the head OF
the list In his profession.
II has been learned that j. Park
Claiming chief engineer of the Miami
Copper company of Arizona, while
here recently made thorough study
of the workings of the Boston Garfield
plant and was so impressed with it's
simplicity that he has ordered the
construction OF an experimental plant
where a system of tests will be made
before beginning the building of
larger and permanent one.
