Mr. Charles NJ, MnoNenl, president

My Dear Sir'-Slnce my communica ton

OF q copy OF a letter written by Manager
. Jackllng. dated Republic, Wash, March
. 2, 1901. and addressed TO Maj r G. Ed
O wards IleclSie, at same place (Which was
received by me by mall from the hand of
Mr.. Jackling), that according to his state
nents as get forth in the letter. he OBJ
tnincd exceptionally favorable results in
the concentration OF several hundred tons
OF the ores from our mine by crushing the
orc with our little five-stamn mill and
. treating the product upon Wllncy tables
+ az long ago as 1899, and doubtless for
gotten by Mr, Jackling.,
. Trusting that any Information that
+, will aid in the solution OF the seeming
i vexed problem Will be acceptable, l quote
p. from Mr.. Jackling's letter as follows
, During the summer of 1899 1 under
&c ok some metallurgical experiments on

Z tons taken from the tunnels and dumps at
4 r3Hdom, The mill which / used was an
Z abandoned hve-stamp mill. without any
Z particular adaptation To the ore, and
without appliances for making a close

+ BY crushing with light stamps to
twenty-five or thirty mesh and concen-
tratlng roughly over Wilfiey table. without
slzers OF any kind. and without any spe-
clal cndeayor to save values from tho
largo amount OF shines produced. | made
a saving Of 7l7-lo per cent. Some ex-
periments made in a rough way by col
Letting shines and running them over a
V&nner, resulted in an additional saving
OF about 10 per cent, or a total saving OF
20 per cent OF the copper values, but |
have based my estimates on u basis of
40 per cent saving.
The latter named per cent of saving
appiisd TO Mr Jackling's present method
would add go per cent To the sum OF net
profit now being recovered
~ Il was present during the greater Dor-
tion OF the time IN which the test re-
1crred TO was made and for several days
was shown the daily assay sheets show

hEinutes' time. the determinations being

average recovery of S01s per cent of the
copper for the first four days work cI-

The operation The test lasted about
lIlrty days. The nrst few DAYS was
under the supervision OF Mr., James For

ViS G9hcentration. he was succeeded by
Mt Henry NJ Crowther, promoter and
LOW general manager of the Continental
Ata Mining company at Alta In this
state. MI lacking visited the property
once during the time and returned on tn,
same day. spent probably an hour al the
lTitl. but this should not dctract from tho
Hdiue OF thc test or the approximate cor
,Sctness OF the figures which he gives, as

prds OF the work as kept at the Mercur
