400, 500, TAO and $40 feet. The
shaft is equipped with machinery,
air-oompressor, etc, capable of ex-
ploring the ground to a depth of
200 feet.
The mine has been shut down for
some time, and in consequence the
levels cannot now be examined until
work is resumed, the mine ventilated
and the surface water, which has
seeped into the workings and accu-
mulated on the bottom level, baled
out. | am indebted to Mr.. John G.
Kirchen, who formerly had charge of
the Golden Anchor, for details of the
mine workings here given The shaft
starts in the "cap-rock'', or later an
| desite, and continues in that forma-
ton to a depth of $50 feet, the 400
and 500-foot levels being in later
andesite. Below $50 feet the shaft
! is in rhyolite to the bottom. An i'm
portant development is made on the
840-foot level, a crosscut run north
encountering the lode-porphyry, or
| earlier andesite, at point 200 feet
from the shaft; thence to the face
(where work stopped in January,
1907, when the mine was closed
| DOWN, the level is in the earlier an
desite. Between 700 and 500 feet
north of the shaft three quartz veins
were cut, which in places yielded as
says. These veins averaged feet in
width only one was drifted upon
the exploration of this deep level be-
ing arbitrarily suspended by the clos
ing of the mine, at time when the
ore-bearing formation had at last
been reached, and before the value of
the veins traversing this section of
the mineral belt could be proved.
Even more important is the long,
exploratory crosscut, run north from
the Tonopah Extension shaft on the
1050-foot level, which passes $50
| feet east of the Golden Anchor shaft,
cutting through the intrusive rhyolite
sheet, and penetrates the earlier an
desite beneath the Black Mascot
claim. This work done by the Tono-
pah Extension, in connection with the
development on the S40-foot level,
north, of the Golden Anchor, deter
mines at this depth below the sur
face the position and course of the
south boundary of tha earlier ande-
site belt. How far this ore-bearing
formation may extend to the north
is not known; all that can now be
stated is that the breadth of the belt
exceeds $50 feet on this one of the
deepest levels in the camp.
THE ADVANTAGEOUS POSITION
OF THE PROPERTY.
The workings of the Tonopah Ex-
tension mine lap the Golden Anchor
territory on the south; the Tonopah
| Extension vein dips north, and the
slopes on the 600-foot level parallel
the south boundary of your property,
from which they are distant $50 feet.
A S0-stamp mill, with a capacity of
1875 tons per day. is now in process
of construction on the Tonopah Ex-
| tension. 1t is estimated that the ore
reserves, between the 600-foot level
and the cap-rock, will supply the mill
for two years. The gross production
to date of the Tonopah Extension
mine, not including the large tonnage
of mill ore upon the dumps. is So
O27,294.9S.
The Midway, also producing mine,
adioins the Golden Anchor on the
east, with ore shipments to date of a
gross value of s1.01l,374.OS." The
Midway is noted for its high-grade
ore; a large ore-body in the Brougher
vein. reaching from the S50-foot level
down to the 4SO-foot level. yielded
