GRINDING OUT ORE
NEWTON ANNEX STAMPS ARE DROP
PING AT VERY SATISFAC-
TORY RATE.
A MOST COMPLETE EQUIPMENT
CAPACITY OF MILL WILL BE TAXED TO
UTMOST WHEN MINE is WORKED
BY FULL FORCE


The Newton Annex mill. which start
ed in operation last week, combines
admirable features, the result of obser-
walton aud investigation of Manager w.
T.. Renshaw, who has inspected many of
the best savers in the country. As nearly
as possible everything is automatic. The
dirt is unloaded from the railroad cars
into ore cars, the contents of which are
dumped into hoppers which automatic
ally empty their contents to the rapid
goes to a chain of Whitley sinners, Frue
vanners, settling tanks. etc.
The mill is well lighted, roomy and
model in every particular. There are
FIVE batteries of FIVE stamps each, all are
independent. This permits the hanging
up of any of the sections without inter-
ference with any OF the Others and in the
event that the management should desire
to treat ores other than from the conf
pany's own mines. such is made possible
by the arrangement.
The expense of treatment is nominal,
but four men being necessary in the mil
ling process One hundred and fifty tons
per day can be put through, making, IN
connection with the Newton mill proper,
combined capacity Of AIS tons. Both
mills are now kept busy upon the pro-
duct of the company's mines, principally
the result Of development work.
As our readers are aware, 1t has been
the intention of Mr.. Renshaw to erect a
Iooo-ton mill at the Newhouse dump to
be devoted exclusively to the reduction
Of the immense tonnage made possible
by the big raise in the Gem mines. This
mill will be erected as soon as the season
permits. II Is said that while Mr.. Rem
shaw has in the past borne the reputa-
ton of building and erecting some OF the
finest mills in the country, this prospect
i've mill will be in advance OF anything
much time and study in the preparations
OF the plans, bringing into use his ex-
haustive examination of the methods
employed in the South Dakota mills,
where ore running s. and s. ton is MT
only treated at a profit, but returns inI-
mense dividends to the stockholders.
The work of extending the pipe line
below town is being pushed vigorously
to secure the required power to carry In
to operation the diversified plans of Mr..
Renshaw. At present 1000 h. p. is
available from that and the present work
will add greatly to it. The Silver Age
mill power, in add ion, amounts to 600.
horse, aud is being utilized at the Gem
mines for hoi ting aud other purposes
The fiue elvc,r.c hosting plant at tine
III ain shaft will he utilized exclusively
for the heIefit of the leasers in the work
ings above the ninth level, hosting them
and their ores to the surface. After the
Levels in contemplation below the ninth
level station have been extended hv
power drills east and west into the noun
tam, there will begin an era of ore ex-
traction and reduction by the company
that can be estimated only by generations
to come. The arrangements inside and
outside the workings of the large terri
tory covered by the Gem mines are espe-
cially adapted to economical handling of
the output, electricity being the motive
power.
The work so far done by Mr. Renshaw
excels that done by any other individual
or company in this section, but the work
that he has in contemplation is of mere
importance in the upbuilding of the
mining and milling industry in this dis
trct than anything yet achieved. 1t has
required persistent effor, and concen;ra-
ton of purpose, the enlistment of willing
and adequate capital, all combined with
an intelligent study of the foremost
methods in milling and mining,
