OLD BONANZA5 COMING
BACK IN TWO COUNTIES.

rush of prospectors to the locality.
Ultimately, Sullivan and his partners
disposed of the Harqua Hala Bonanza
and Golden Eagle groups to Phoenix,
Arizona, parties. The latter proceeded
to open them up in a manner calcu-
| lated to produce the greatest immedi-
ate returns. They erected 20-stamp
mill and in 80 days cleaned up $4,000
worth of gold
In the course of time the properties
were purchased by ap English syndi-
cate. An incline shaft was sunk by
the Britishers on the Harqua Hala
group to a depth of 200 feet and the
property thoroughly equipped with
mine and mill machinery. 1t is said
they mined s4,OO0,OOO worth of gold ore
above the 200-foot level The bullion
was teamed to Phoenix-12O miles dis
tant Road agents infested the trail in
those parlous times and as result OF
bullion from the Harqua Hala and the
Vulture mines failed their destination
In fact, the manager of the Vulture
mine, while conveying bullion to Phoe-
nix, was robbed of gold avlued at $780,
900 and killed by bandits. After that
episode the Harqua Hala bullion was
i,,+o 10
and weight the bandits could not make
way with them across the arid
stretches. Shipments of ingots having
a value of $365,OOO each were for
considerable period sent out from the
property.
The "Bonanza Cave"
Owing to the long freight haul, the
scarcely of wood in a country of dwarf
sage and mesquite bush, and the con-
sequent high price of mine timbers,
the latter were sparsely used. AS the
ground was opened and stopped the GUS
tom was to leave Supporting pillars of
ore, much of which was high grade
While attempting to remove these pill
lars, in later years, the ground caved
from the third level to surface for
several hundred feet in either direction
from the shaft, leaving an immense
chasm extending from the footwall to
the hanging wall breadth of 70 feet
and laterally along the vein workings
a distance of 400 feet. This great cav
ity is known as the Bonanza Cave .
1t cut off all access to the mine work
ings and forced the Engnsnmen to sink
a new shaft. The latter is located
About 400 feet west of the old shaft and
the incline. Connection was made with
the second and third levels of the old
workings.
In drifting southwest from the new
shaft an immense Tbooy of ore was
opened and stopped The tonnage ex-
tracteo milled $2,OOOOOO worth of gold
bullion. This stope is of enormous
proportions and presents the appear
ance of a natural cavern rather than
the handiwork of man. Due to it's un-
usual size and shape the miners called
it Castle Garden" On the same level
an attempt was made to get under and
draw the ore. from the Bonanza Cave
through medium of crosscut. AS
this crosscut was driven under the
Cave on the hanging wall side it
stable nature of the caved ground, it
could not be successfully timbered.
Ultimately, this crosscut caved to the
solid rock below. These reverses were
intensified by a barren streak in the
vein, and the Englishmen, becoming
discouraged, quit work.
The Present Regime
About three years ago the Yuma
Warrior Mining company, close cor
poration controlled by Chicago, ILL.,,
Prescott and other Yavapai county
business and professional men, took
over the Harqua Hala Bonanza and
Golden Eagle groups. Since then the
the properties have been undergoing
development almost continuously The
deal included 4Q-stamp mill, arr
drills, compressors, hoisting machinery,
and full complement of camp equip
ment and underground mining appar-
atus, together with an aerial tram
about seven -eighths of Amile long
running from the Golden Eagle shaft to
the Harqua Hala Bonanza milling
plant A pumping plant and a water
supply more than ample for camp and
milling needs were also included in
the deal.
Last February the company began
milling the ore mined during the or
dinary course of development, and to
date has shipped about $4,000 worth
of bullion. Work is at present con-
fined to the exploration of new ore
bodies that have been found in the
Harqua Hala Bonanza mine. Geologi-
