The Times-Review Describes This
Up-to-Date Plant.
The Times Review, of Tuscarora,
New, contains the following descrip
ton OF the new Dexter mill at that
place, which began dropping stamps
day before yesterday, viz:
Twenty stamps of the Dexter COM
pany's new 4O-stamp mill will drop on
ore today.
Work on this fine structure was COM
mrnced on Oct. 5 of last fall, and now
the company has one of the finest gold
mills ever erected in the west. Every
stick of timber used in the construction
is of Oregon pine, and put together
with a view TO strength and perma-
hence. The contract was let to the Colo
RADIO Iron Works of Denver. through
their agent, M. A. NJ. Grant, nnder
whose supervision, with that of his able
assistant Mr.. S. L. Watson. the work
has been successfully and satisfactorily
completed. The company have spared
no expense in making the entire plans
complete IN every respect, and every
thing was selected and put together
with a view single 20 the idea of max
ing the mill a perfect one.
GRAVITY WILL BE UTILIZED
to the fullest extent, and from the time
the ore is mined until it reaches the
tailings pond at the cyanide plant, no
handling Will be required
The mill is connected with the mine
by a trestle work which enters il at a
height of nearly 40 feet. This trestie
is all of Oregon timber, and some 10000
feet were required in its construction
The ore viii be transferred from the
chutes at the mine in 5-tcn cars run
ming over . track laid with 16-pound
rails. with sufficient grade TO permit
the cars TO run to the mill by gravity.
Here the finer particles of ore will pass
through the grizzlies, while the coarser
materials viii be run through the jaws
OF a powerful rock breaker. which
weighs nearly FIVE TONS. into the ore
bins beneath. From the bins the ore

which viii regulate the quantity Of ore
automatically to the requirements OF
tie battery. The battery is composed
of stamps of $50 pounds each, with a
drop OF eight inches. and are capable
of reducing about one and a half tons
each of hard ore in q hours The NOR
tars are of the latest pattern in use
in all the up-to-date mills Of the coun-
try, and contain plates which will catch
e large proportion of the precious
metal. The pulverized mss viii be car
ried through a fine screen over the
large plates, flowing from thence to the
ELLIS CONCENTRATING TABLES,
eight in number. which are design
ed to save such sulphurets as the ores
may contain, together with what free
gold may escape from the amalgamated
plates. These tables were invented by
son of one of the principal owners of
the Dexter, and have been successfully
used in several districts where the re-
quirements are a delicate adjustment
suitable to the separation of materials
of nearly equal specific gravity. They
are designed after the plan of a vanner,
with numerous depressions in the belt,
which is given a rotary motion similar
TO that employed in manipulating a
gold pan by hand. After passing these
tables, the tailings are conveyed by a
numc TO a point near the cyanide plant
some distance below the mill, where
they are allowed TO settle, and then
subjected TO the solvent
ACTION OF THE CYANIDE SOLU-
TON,
which viii remove practically the last
trace .of the precious metal.
It is in the question of power that the
has made its mastery stroke,
and entirely eliminated that vexatious
problem which has always been a ham
dicap in the reduction of low grade ores
in this camp. This they have accom-
plished by Harvesting the power of Nj
