Company.
JAcKLING MADE A REPORT.
For Which lie Received $4,000 in 1899
Would Follow NcwlIousc
Method.

Col r. a. Wall has written another
letter to President Charles NJ. McNelll
of the Utah Copper company In which
he again alleges that grave mistakes
have been and are being made In
the construction OF the proposed
concentrating mill, which is TO be
known as the Goldheld plant. The let
ter reads as follows.
Salt Lake city Jan. 81, 1906. Charles
NJ Mcneil. President Utah Copper Co,
New York Clty.--My Dear Sir. Since
my communication OF the oath inst,
find upon examination Of Il copy OF a
letter written by Manager Jackling.
dated Republic, Wash. March 20. 1901,
and addressed to Mai r. c. Edwards
l@ckie. at same place (Which was re-
ceived by me by mail from the nand OF
Mr.. Jackling), that according TO h.s
statements as set forth in the letter, he
obtained exceptionally favorable results
IN the concentration OF several hundred
tons OF the ores from our mines BY
crushing the ores with our little FIVE
stamp mill and treating the product up
on Wiley tables, as long ago as 1899.
and doubtless forgotten by Mr., Jack
ling
Trusting that any information that
Will aid In the solution OF the seeming
ly yexed problem will be acceptable,
quote from MIR. Jackings letter as fol-
lows:
EXPERIMENTS OF 1899.
During the summer OF 1899 under
took some metallurgical experiments
n nd
hundred tons taken from the tunnels
and dumps at random. The mill which
j used was an abandoned nye-stamp
mill, without any particular adaptation
10 the ore. and without appliances for
making close saving.
by crushing with light stamps to Is
or 3O-mesh. and concentrating roughly
over Whitley table. without sizers of any
kind and without any special endeavor
TO save values from the large amour,
of shines produced | made a saving OF
III per cent, Some experiments made
In rough way BY collecting shines and
running them over vanner, resulted
In an additional saving of about 10 per
cent or a total saving Of 80 per cent OF
the copper values, but ! have basel
my estimates on basis Of 10 per cent
saving"
The latter named per cent Of saving
applied TO Mr Jackling's present meth
cd would add $50 per cent TO the sum
Of net profit now being recovered.
| was present during the greater por-
ton OF the time in which the test re-
ferred TO was made, and for several
days was shown the daily assay sheets,
showing contents OF heads" "talls'
and product, taken at regular intervals
~ a few minutes time the determine
lions being made by competent assay
er on the ground.
The actual results showed an aver
age recovery OF sGis per cent OF the cop
per for the first four days work, ex-
elusive Of values contained In the
shines. which We're then being stored
for future treatment. with what rc-
suits | never knew. as at that time In
structions were received from the De-
lamar head Office 10 withhold further
information from me, and thereafter
paid little attention 90 the operation.
The test lasted about 30 days,
The first few days the test was under
the supervision OF James Forester, an
expert OF exceptional ability In ore con-
concentration. He was succeeded by
Henry NJ. Crowther, promoter and now
general manager Of the Continental AL
ia Mining company ut Alta In this state
Mr. Jaclll visited the property
once only during the time, and returned
on the same day spent probably an
hour az the mill but this should not
detract from the value of the test or
the approximate correctness Of the fig
ures which he gives. as they were
doubtless taken from the records OF the
work as kept at the Mercur and Salt
Lake Offices.
Al a later date ] arranged with Mr.
Jackling for copies OF reports and all
data collected by DeLamar's engineers
drring an exhaustive examination made
OF the property, including the mill test
referred 10, for use In an endeavOr TO
enlist come friends In a repurchase OF
the quarter interest In the property
which ! had peyiously sold to Capt.
DeLamar, and had agreed, In case
should make successful use Of the data,
TO pay him $1,000 for It.
