which, farther to the south, is the
main ore-channel of the district.
After driving east about 700 feet
from the main shaft this vein was
penetrated and the cross-cut has ex-
tended through and beyond the vein
and is being continued 70 cut the
parallel Rabbit Trail vein. A south
drift from this cross-cut, following
a course neal the hanging wall of
the fault vein, has exposed a body
of ore that appears to be CT large
dimensions, having been opened for
a width of IL feet at n point,
and has been yielding assays in
gold, copper and silver many of
which are near the shipping grade.
The vein has never been explored
at depth this far north and the
fact is significant that large bodies
of good mill ore were found on
the 120-foot level, at a correspond
ing section of the vein.
Red Hill Florence
Three raises are being driven
from the 5OO-foot level of the Red
Hill Florence, two near the hanging
wall and one near the center of the
big lode, and are showing strong
seams of good ore. One of these
raises has made a particularly good
showing and the ore at this point
seems likely to open into a deposit
of commercial grade and size. The
property is being developed in a
comprehensive manner, with a large
force of men and with the aid of
an excellent surface plant.
Jumbo Junior
From the main north drift on the
SS0-foot level the Jumbo Junior
company is sinking a Wine. follow
ing the dip of the vein, and has ex-
posed an oreshoOt that is now show
ing two fee of ore averaging $101
per ton in gold and copper. This
ore is now being broken for ship
ment. The point at which this ore
is exposed is within territory leased
from the adjoining Kewanas and
about 100 feet north of the joint
boundary. Near this point a raise is
also being driven and after pro-
crossing too far from the wall is
again coming into the ore-shoot
and showing good ore.
Great Bend Mine
Regular shipments of ~high-grade
ore have been continued from the
Great Bend mine, where a product
of excellent average grade has been
showing on both the 100 and 800
foot levels for a considerable dis
lance. Smelter returns for the last
two or three carloads shipped have
been or a basis of from $72 to SIS
per ton, and it is indicated that
the company's profits for the month
of July will reach a substantial fig
ure. Constant improvement has
been reported in the condition of the
mine, which is now making the sec
ond most valuable production in the
Goldfield district.
Grandma Consolidated
AL a ueptn OF ABOUT 4oO leet the
main shaft of the Grandma Consoli-
dated is showing a marked change
in the character of the formation
and apparently is entering the
latte, in which most of the rich
ore-bodies of the district have been
found, The last few rounds have
shown what appears TO be an altered
andesite and above this were some
small intrusions of broken shale. but
no dacite has appeared. The change
is reported by Consulting Engineer
Turner and other authorities as
pointing to the possibility of cut
ting an ~ore-bearing zone at any
time, but the present plans of the
company contemplate sinking with
out interruption to the shale contact
zone.
