MANHATTAN, Nov. 5.-The opera 9
ions in the Wittenberg ten /
stamp mill on White Caps oxidized
pres is surprising expectations. On {
pres averaging ten dollars, gold CON !
tent, the final tails run from 40 to go
per cent. The use of the mills
stamps and tube mill for one shift
in the day brushes from 30 to 35 tons
Of ore. The ore is coming from the
glory hole work in the east ore body.
Churn drill holes breaking down rock
from between walls 35 feet apart.
This is dropped from near the sur
face, where the miners are at present
working, to the first level into large
chutes, from there trammed to the
shaft, holsted, and dropped through
large grizzly into the receiving ore
bin. The grade of the ore is raised
one-third by the screening process.
The mining operations since the mill
started to treat White Caps ores /
shows total mine cost OF 81 per
ton, but this will be still further re-
duced the coming month. A raise is
being extended in the west ore body, I
to connect with the first level 1t Is
now up from the bottom level about |
seventy feet, still showing the black
sulphide ore, averaging from $50 to
$40 per ton. AS soon as Mushett and
Wittenberg have their new mill in
stalled on the Big Pine, the, White
Caps will take over the mill now be-
ing used by both operators, and then
will treat an average of sixty to
seventy tons each day, thus reducing
still further the low mill and mine
costs. A close estimation of the oxi-
died ores in the White Caps made
by Engineer John NJ. Fox last month,
shows $4,000 worth of ten dollar ore
available with probable and possible
ore exceeding that amount from Is
to 25 per cent. This ore will be
mined, hauled two miles and milled
at cost not exceeding "a per ton.
Mushett and WittenbeEg the opera
tors on the Big Pine have their new
mill en- route, and it should reach
Manhattan within ten days from date.
Grading for the mill-site has already
commenced. But the last of Novem-
Der the mill should be in operation.
It comprises a large tube mill, by
90 feet dimensions, Dorr classifier,
amalgamating plates, etc. The Blake
crusher now installed at the collar
Of the Big Pine working shaft will
serve to do the coarse crushing for
the new mill When installed and In
operation, minimum of 200 tons per
day will be handled by the mill, and
it is expected that there will be no
increase in the average present mill
tails on the Big Pine ore. These
tailings now average from 40 to so
cents per ton.
On the Big Pine property the two
glory holes being operated north Of
the working shaft have now been
merged into one. The dimensions of
the workings on the surface being 300
feet in length by 40 feet at one end
and 100 feet on the other, Four
miners break all the ore necessary
to keep the mill going, the average
rock hoisted being over 200 tons per
day, which after crushing and screen
ing means 100 tons to the mill. One
jack-hammer drill is utilized in the
glory hole work, the first six feet
of the holes being put down with the
air drill, and the last four feet. churn

On the Manhattan Dexter the opera.
ern portion of Union Mine claim are
proving that there is still great deal
Of high grade mill ore to be mined
throughout the old Plamenaz work
ngs. Meissner and Cochran have
developed fine shoot fore. in a
portion of the Moore vein north of
, the Plamenaz vein, from the 325-foot
: level This new ore leads into virgin
ground ard means that the vein will
have at least $50 feet of backs. The
: pumping operations from the 400-foot
level of the main working shaft on
Union Nine furnishes the water for
the Wittenberg mill wherein
the ore from the Big Pine and also
the White Caps is being milled. AT
