THE HOGAN MINE TO
Be PRODUCER IN
THE SPRING
1T IS SAID TO BE LARGEST BODY
OF COMMERCIAL GOLD IN
THE NORTHWEST.
TO HANDLE LARGE TONNAGE
Much New Machinery is Bought and
Will be Operated by Direct Water
Power from Crooked River.

The resources of the Hogan mine
at orogrande, Idaho, which embraces
the largest deposit of commercial gold
ore in the northwest, according to en-
gineers, is to begin the yield of its
metallic content beginning next May
by our calculations" said j. u. Pick
rell, secretary treasurer, in his office,
Columbia building, yesterday. Judge
George Turner and several business
men are identified with the enterprise
"There are 100000 tons of ore in
sight in a section of the dixie 800 feet
that embraces the greater glory hole,
which was the subject of development
and extraction by earlier operators,
and this great body is traceable
throughout the length of the property
for two miles, proven in several places,
affording possibilities like the Home
stake of North Dakota. The deposit
has been proven to an additional depth
of 100 feet in an opening south of the
river.
'When the Orogrande company shall
have completed its improvements, $780,
600 will have been invested in opening
and equipping the property, part of it
by predecessors. Former operators re-
moved gold valued at $l25,000, and
made little money. They lacked the
advantage of modern methods of ore
dressing essential to high extraction
which we are bringing to the operation.
"They employed amalgamation and
cyanidation by which an extraction of
33 to 40 per cent was obtained. Tests
have, shown that we will be able to
make an extraction of 80 per cent with
an equipment that includes stamp mill,
two tube mills, two classiIiers, II
thickeners, -four agitators, cyanide
tanks and other apparatus of recog-
nized efficiency in this work.
While the rate of extraction will
be upward of 100 per cent greater
than the best rate of our predecessor,
the tonnage handled will be three times
larger and the number of men employ
ed less, the latter economy being made
possible by gravity and automatic sys-
TENS of handling. Former operators
received their ore through grizzlies
from the glory hole and loaded it by
hand into cars for movement to the
mill. We will move the ore from mine
to mill by revolving shovel, greatly
reducing the item for labor. We expect
to mine and mill So ore at cost of s 4
ton when the plant is running at
capacity and the cost of milling sup
plies is at normal. The initial capa.
city will be 300 tons day, but this will
be increased manifoldly as development
| proceeds. The rock is an altered gran
! ite gangne, according to Robert n. Bell,
state mine inspector, and other engi-
neers.
1--WE have placed an order with w.
| H. Agens of the Union Iron works for
500 900 worth of machinery. The tube
mills will be delivered next month.
The mill will be operated by direct
water power. Water will be brought
in from the head of Crooked river, a
distance of five and one-half miles, by
ditch which we have completed with
the construction of the year closed. 1t
will be dropped 4S7 feet through pipe
having length of 1850 feet and
diameter of 16 inches at the head and
Il inches at the mouth, and will drive
one of the largest Pelton wheels in this
part of the country. We have saw
mill, with which our building material
has been prepared, and will have an
electric light plant.
ssThe property consists of 400 acres
of which $50 acres are a placer bed.
The placer property, which is virgin

with hydraulic giants.
