FARMERS MILL A SUCCESS

Per Ton

Perhaps no topic has been az v;ae,v
discussed during the last wear. nnlass
u be the rebuilding oil the Eureka q
ralisade Railroad. as the subject as to
whether or not the new cyanide reduc.
lion mill Of the Farmers Mining Com.
pany. designed by Geo. L. Kaedine.
would successfully treat the ores Of
prospect Mountain. 1t is therefore
with q full realization Of the Importance
to Eureka District of such an assertion
that the SENTINEL is able to state to its
readers that the mill and process are 10
every way q success and fully up to the
expectations Of the company and Mr..
Kaeding.
In the SENTINEL Of June 10, 1909.
after completing the first mill for the
Windfall Mining Company, Mr.. Kaed-
ing stated that in his opinion there we're
other mines in the district whose ores
could be treated by local reduction
works. This statement has now
been proven to be true as far as the
gold-silver ores Of Prospect Mountain
are concerned, and Mr.. Kaeding has re.
Gently stated to the SENTINEL that in
MS opinion. 1t Is merely a matter of
experimenting and design to build local
reduction works that will successfully
treat the silver ores such as are now be.
shipped from Adams Hill aud vicinity.
With . concentrator to concentrate the
wet ores Of the district. such as are
found in the Holly and some other
mines. Eureka District would be able to
make profitable production from many
mines that now lie idle and which have
not been worked since the local shelters
ceased operations.
IL has always been asserted, and is
still believed by some. that the arsenic
contained in the ores of this district
p~recluded successful treatment by the
cyanide process, bat in the treatment
OF the ores. as designed by Mr.. Kaeding,
the extraction Of the gold and silver is
so rapidly obtained from the finely
divided or slimed particles of ore that
the arsenic compounds and base metals
are not in contact with the solutions
for . sufficient length Of time to be in
furious.
The Farmers mill commenced opera
tions on September IS aud, except for a
few days shut down, has been in con.
tinuous operation since. Owing to tie
failure Of the Oliver Filter to treat more
than So ton per day the capacity of the
plant has been limited to that tonnage,
but ii is the intention Of the company
60 Immediately bring the filter up to a
l00-ton capacity or else install another
dlter. Even with the difficulty expert.
enced with the filter the extraction has
been over 81 per cent. and when this
machine has been perfected the extrac'
ton will be over 90 per cent. With a
milling cost of less than $3.50 per ton
this extraction will leave a handsome
profit even on the lowest grade ore.
The past two weeks John Reinmiller,
one OF the most successful mine mana
gers In Nevada and at present mine
superintendent Of the Pittsburg.S Silver
Peak Gold Mining Company at blair,
has been making a detailed examination
Of the property Of the Farmers Mining
with particular reference to
the ore occurrence and the possibilities
Of cheap mining. Mr.. Reminders
work in the cheap mining OF ore is men
elsewhere in this issue.
The Farmer Mining Company will
probably decide to shut down the mill
as soon as the freezing weather sets in,
devoting the interval until Spring In
doing certain work in the mine and
mill which can be done during the shut
They will then be ready to go
ahead at full capacity as soon as Spring
opens.
