The Arizona copper camp., 1920-04-10

define a body as ore blocked out in
the parlance Of the engineer, but it L
does offer encouragement for a more
complete investigation of the posi- |
bilities of the deposit. The presence
of water in such quantities and the
absence of sulphides at depth of 500
feet will lead one to wonder what will
be brought forth at the sulphide zone
ter of the vein gives considerable hope
for secondary enrichment.
The property is in the country that|
has Teen prospected more for silver
and gold than for the base metals. i
The old Pioneer mine, now being op-|
Grated by the White Metals Mining
company, is about six miles away and
is claimed to have produced over ST.
100000 in silver. The Pinal Develop
ment company work adjoins the Drip
ping Springs, the old Troy mine is
close by, while the Rather, Hayward,
Cowboy and other surface producers
of old days are all in the immediate
vicinity. In all of these no material
depth has been attained and, in fact,
outside of the few large ones, such as
the Ray Consolidated, Ray Hercules
and Christmas mines, there has been
little real systematic exploration.
The finding of commercial ore at 9 |
depth of 500 feet, while it's full extent
is not yet known, will mean much for
the future development of the district,
which, many people have believed had
it's values confined to gold and silver
on the surface. 1t is certainly true
that the Dripping Springs Copper
company will follow UP their find rap
idly, with view of getting the prop
erty into shape for shipping as well
as further exploration in the crosscut
and at greater depth. Work has al
ready started on an ore bin, although
the conditions of the Dripping Springs
property are such in regard to trans
portation that considerable road work
will he necessary for the satisfactory
truck haulage of the ore to the lead
ing station at Christmas
For some time the Dripping SpringsI
Copper company has been operatingI
another mine, shipper, nine miles
from Mammoth and 20 miles from
Winkelman in the Catalina range.
While the property, which is known
as the Pearl mine, is in process of de-
velopment, it has been paying prac-
tically all of it's development costs
from ore shipped, five men mining
four tons a day, using hand steel,
Three cars of ore have been shipped
from this property since January l.,
which have been netting above smell
ter charges about $500 per car The
ore at the Pearl is silver and copper
with no gold and only 180 feet depth
has yet Leen attained, although the
present shipments have come from
sinking.
1t is probable that the Dripping
Springs property of the same COM
pany will be made to do partly this
same proposition, the paying for its
development by shipping, provided the
ore stays with them. 1t is hardly toI
| be expected that the crosscut deposit
recently found will not be reasonably
continuous and the assays so far made
show that it can be shipped at al
profit. However, the deposit will re-
| quire considerable opening up in prep
aration for economical methods of
handling and particularly if it is de-
sired to handle any large tonnage.
Some of the most prominent and
promising of the veins of the Dripping
Springs series are yet to be reached
Ey further driving of the adit in which
the ore was encountered. Large and
well mineralized veins show up on thel
hill and when the tunnel gets under
them, they will have still greaterI
depth, for each foot of the tunnelI
makes at least another foot or more

Ee A series of several such deposits asl
already found will make tonnage very
| fast and the long crosscut can easily
be widened and Strengthened to bel
used as haulage tunnel It's mouth
| is conveniently located both for trans
portation and accessibility for equip
ment. A railroad to the tunnel isl
easily within the realms of possibility.
1t is hoped for the benefit of the
district as a whole that the Dripping
Springs Copper company will follow
up their advantage to the utmost, to
develop rapidly large shipper, to get
| further depth and see what the sui
phile and secondary zone will bring
forth, for they have had the encour-
