THE MILLS OF MERcUR.
The Substantial Growth Being Made
BY the Camp.

IAC
A special from Mercur to the Den
yer News says:
So much has Mercur changed during
the present year and so rapidly has the
output of the mines increased, that
those familiar with its past history
would scarcely believe it possible that
things could change so much. There
are now six mills running in the dis
trict, one completed ready for work,
one that will start next month, and one
that will be ready Oct 1.
The Golden Gate mill has made
very successful run, 800 tons per day
being their present output When the
plant first started the extraction was
about 70 per cent, and this has been
steadily increased until today an aver
age of 80 per cent is being saved. This
includes the arsenical ores, as well as
those that are ozidized. There is no
shipment of cyanideS, the refinery at
the mill turning out gold bars, which
are shipped as fast as they are pro-
duced, so that but little is left around
the mill, and the shipments are small.
About 81 900 per day in gold is obtained
from the ores being worked. A large
force of workmen is at present en-
ployed grading for an addition to the
mill, which, when completed, will have
a capacity of 1000 tons per day. The
structural steel and the new machinery
are beginning to arrive, and it is ex-
pected that the work of charging Will
be completed within the next month.
The Overland mill is rapidly nearing
completion, and there are good reasons
to believe that everything will be in
readiness by October. The mill will
have a capacity of 200 tons from the
start, and will be added TO in snort
time. The extent of the ground owned
cT1 Of Ia n
nificent ore bodies the uniform values
found in the different parts of the mine
and the good teaching qualities of the
ore cause the mining men Of the camp
to believe the Overland will before long
rival the Mercur in size and value.
The Mercur company is doing great
deal of development and exploration
work in its property, and, as natural
in the oldest property in the camp,
pointing the way for other mine own
ers. The results have been gratifying.
Four years ago but one vein was
known in the district; a year ago 1T
was demonstrated that there were two
veins running parallel at distance
of about 40 feet, sometimes approaching
within few feet of each other, and
again having large bodies of hard blue
lime rock between. Today five veins
have been discovered, and great deal
of development work has been done
in each When De Lamar held an
option on the property about Is months
ago, his expert reported little over
81 900 GOO in sight. 1t is no eXaggera-
ton to say there is at least three times
that much in sight today. The COM
pany is getting the mine in shape to
supply another mill of 800 tons capac-
ity, TO be built at the mine, and 1t is
expected that this will be done in
short time.
When the company first commenced
cyaniding their ore they made the mis-
take of grinding too fine. This was fol-
lowed by grinding too coarse. Other
mistakes were made, which only eXpe-
rience could correct. In the old dump
it has been found that from So to 81
per ton was left in the taiingS. Today
from so cents to 81 is the average
amount of ore left after the teaching
process Experiments have demon
strated that for a cost of less than 81
per ton the tailings can be passed
through the crushers and leacheG over
again, and net profit OF Sl5O TO " |
per ton made for the company. Care |
full estimates have been made, ana IL is |
found there is at least 100000 tons of |
these tailings, from which a revenue |
can be made. This would keep the pres
ent mill busy nearly two years, and |
add a revenue of about $4,000 per month |
TO the net profits of the mine. 1t has, |
therefore, been decided to erect a new |
mill of large capacity for the treat
ment of ore at the mine, and put the |
old mill to work on the tailings.
The Daisy mill has made its trial run,
and the record is unprecedented From
the day when the first wheel turned it
was unnecessary to stop for changes
of any kind except the Tightening of |
belts. A hundred tons per day are now
being treated, and an extraction Of 80 !
per cent of the ore values has been
made from the beginning. The first
shipments of auro-cyanides was made
a few days ago, and the results were
very satisfactory to the management
and stockholders.
The Chloride Point mill has also
made a start and is meeting with
marked success. The ore is silver
but carrying about s. per
ton in gold. The time required for
teaching is eight or nine days, and
about 70 per cent of the silver values
