The Mereur Mercury, in it's last is
sue, gives the following interesting de-
scription of the modus operandi of the
new Golden Gate mill, now in course
of erection:
IN order to give our readers at least
a faint conception of the great works
which Captain DeLamar is construct
ing for the Golden Gate mine, we pub
lish the following description Of the
milIsite now nearing completion: The
{ site is at the head of Main street, Gov
ering the side of the Golden Gate hill
! facing the vest The site. not includ-
( ing the gas plant, covers a ground
{ space Of 800 feed wide and 400 feet ionG,
and is composed Of eight levels, sup
ported by solid walls of masonry, some
/ Of which are 40 feet high.
The top or cPusher level is 75025 feet
| in dimensions. The ore, coming up
through the incline, which leaves the
working shaft at d point about So feet
! below the surface OF the ground, pass
{ ing under corner OF the mill and
! emerging above the first level, Is
! dumped automatically into the crush
! ers, where it is coarsely crushed and
runs into bin with capacity OF 2,0OO
! tons Above this lever, 100 feet, is the
shaft house containing the air COM
pressor and hosting engines, which
| lift the ore from the bottom OF the
mine to the top of the mine Above
/ it also runs a great fue, which comes
! from the furnace levels below, connects
| with the dust chambers, runs up the
hill for 200 feet and is crowned by a
perpendicular stack 81 feet high This

with the main fiue. After the moisture
! is expelled by the driers, the ore passes
( automatically to the
THIRD LEVEL,
where all the rolls. screens and eleVa-
! tors are situated. This level is 90X6S
I feet, and here the ore is finely crushed
| and screened and passes into second
ore bin, 25NS4 feet. capable of holding
1900 tons. This ore BIN rests on three
| solid walls of masonry. Under this ore
( bin is the
DUST CHAMBER.
which is 100 feet long and l0Nll teeJ
inside dimensions, This chamber Is
connected directly with the main due,
and is provided with hOpperS j. feet
apart the entire length. Fhe floor is
SO arranged that the dust collects at
! the mouth Of these hoppers, so that 1t
! can be drawn off into cars below with
/ out shutting down the plant for an in
slant. a door also connects With the
main fiue at this point, at which all
dust accommodating therein may be
! drawn OFT in the same manner as from
the hoppers in the dust chamber. From
{ the third level the pulverized ore goes
automatically to the
FOURTH AND FIFTH LEVELS
directly 70 the roasting furnaces. Each
( of these levels cover q space 29Sx33 Id
feet, and on each rests two furnaces
! 1875 feet long and 16 feet wide. Under
! the furnace levels are two hues IS feet
I long. 61S feet inside, connecting with
( the main dust chamber and running
under the ends of the furnaces, with
! which they are connected. These fur
naces have a capacity of 800 tons day,
and here the ore is parted from all
arsenical and other minerals which in
} terfere with the treatment by the pro-
/ posed process. The
SIXTH LEVEL,
which covers the same space as the
! fourth and fifth. is left blank. 1t is
made for the purpose OF adding two
( more furnaces, when it becomes deslr-
4 able to enlarge the plant, and by this
/ advancement the addition can be made
without stopping the mill for day
I After going through the furnaces the
ore drops into a hopper excaVated from
/ the fifth level, which is connected with
the seventh level by tunnel which
runs under the NTH and sixth levels
( and comes out at a point above the
5 tops of the tanks on the seventh floor.
! Until the hopper is reached the ere has
been handled automatically. Here the
ore is drawn off from the hopper into
{ cars and run out over the tanks on the
SEVENTH Level.
and dumped into them. The tank room
: has dimensions 298 by 90 feet and the
( tanks are supported by d solid retain
{ ing wall and 230 heavy piers of mason
/ ~, which 90 down to the living rock.

( capacity of 200 tons each. Above them
on the same level will be the solution

/ tanks. The tailings can be dumped at
( both ends of this level and ample space
has been left for more tanks if found
necessary when the extra furnaces are

EIGHTH AND LAST LEVEL
| is 80 by 20 feet. and here the solution
from the tanks above is precipitated
and relieved of its golden burden. Here
also is located the main solution stump.
; On the south of the fourth level is To-

GAS PRODUCING PLANT,
which covers a space 80 by So feet. It

The foundation of the mill is now
practically completed, and inside q a
