the Combination, as the grade is
much higher.
The haulage way in the Combina-
ton is being driven south toward
the Florence boundary line and will
be continued over the line into the
Reilly lease territory, one of the
richest blocks of ground opened in
mining history. As was indicated
recently by F. Sommer Schmidt,
manager Of the Florence, this ore
should be of higher average grade
than the, average grade in either the
Red Top or Combination, as it was
not. reworked after. the early day
leases expired.
The Development company, in
mines and mill, is employing 125
men in the preliminary work, which
has practically been completed
everywhere but in the Florence.
The date now fixed for starting the
mill is September 1. All machine
work, which includes new shafting
and bearings in all parts of the mill
and difficult repairs to the stamp
batteries, has been completed, and
only the delivery and assembling of
remains before the plant
can be started.
A. L. Darcy, vice president and
uouo0or of tho Dovalnn-
ment company and who has been
engineer for the Tono-
pah Divide and other Divide dis
trict companies, resigned on August
5 to devote his entire attention to
the Development company. The De-
velopment company generally is sup
posed to have been born in the
brain of Darcy. Harry Mcmahon

Dean Bradley of San Francisco, a
noted mill expert, was given the

His task in the preliminary

about that date he will have accom-

For some time there have been

regarding the mill flow sheet
and in his reply, in which he re-
briefly the work hat has
been done to date in preparing the
mill, he said: mo change will be
made in the method of precipitating
the gold in solution by zinc until the
flow sheet for the 2000-ton plant
has been developed" This shows
that the company definitely is pre-
to enlarge the mill.

Mr.. Mcmahon last discussed the
for opening the mill on August
Is and at that time he set the date
about September first"
From August Is, when the first
ore was dumped into the mill bins,
trial runs have been made to de-
termine the proper metnoS for re-
ore to the fineness neces-
scary to recover the maximum me-
taIlic content. The hardness of the
quartz gangue in the ore made it
questionable whether grinding in
ball mills directly after crushing
was feasible and it was thought by
the metallurgists conducting the
experimental work that 1t might
be necessary to resort to stage re-
duction. On August Is laboratory
we're in progress and until
completed no definite decision
could be made upon the flow sheet
to be adopted.
However. some notable changes
in the mechanical operation of the
mill were being mace. The old
launder system was being entirely
removed and devised SO as to make
all fumes accessible and the plate
in front of the batteries was
being raised to the level or the NOR
