KATHERINE MINE
SAID To HAVE
MADE STRIKE

HiHUL UiufIkL
KINGMAN, Arizona, July 9.-Min-
| ing operators in the recently estab-
lished Katherine district in Union
Pass are jubilant over the reported
discovery of high grade ore on the
400-foot level of the $4,000,00O bon
ANA that Charles Sutro and asso-
ciates, of San Francisco, are develop
ing in the south end of the camp in
proximity to the Colorado river. The
new strike was made in late June on
the fourth level-the deepest point of
development in the mine-at a point
well to the east of the shaft, and is
said to show an abundance of gold,
in the free. The vein there, as on the
levels above, is a solid quartz re-
placement of calcite in the granite
and is said to be 81 feet wide be-
tween walls. lens seven feet wide
carries al gold content of 1920 ton.
The strike on the lower level of
the Katherine mine was antedated
about two weeks ago by the discoV-
cry of high grade ore at a point 700
feet west of the shaft on the 2U0-foot
level, where lens IL feet wide car
ries a gold content as high as $500
ton On the third level the gold
values average $50 gold a ton across
a breadth of 81 feet, exclusive of
lens six feet wide that averages 1898
gold ton. On the second level the
gold values average 1922 a ton across
breadth of 16 feet, while on the
first level there are number of
ifoa fol cix
which average 500 gold a ton.
Ledge $500 Feet Long
This mammoth ledge, known as the
mother lode of the Katherine dis
trict, passes southwest-northeas
through the Katherine estate for a
length of $500 feet. Southwest of
the Katherine workings the course
of the vein appears to be through the
/ Pyramid propertp about a mile dis
tant. 1t will, however, require fur
Their development work in the Kath-
crime mine, and beyond, to determine
the true course of the vein through
the properties to the south as it
shows pronounced faulting. The re-
cent discovery of the Katherine vein
west of the Katherine shaft-for the
first time in the Katherine workings
will serve as a guide for the ex-
ploratory work being done by the
owners of adjoining and adjacent
acPeages to the southwest.
Northeast of the Katherine proper
ty the course of the vein, despite its
faulting, has been pretty well deter
mined for considerable distance.
The site of the shaft ON the adjoin-
ing Katherine Extension property
was determined by an underground
of of unr.lyi N
At depth of 100 feet the Extension
shaft passed out OF the overburden of
wash into solid formation, and at a
depth of 200 feet entered what APP
pears to be the casing of the Rather
inc vein. The shaft will be deepen
ed an additional so feet, which, al
| lowing for the topography of the
| country, will give it a depth cores
ponding to the 200-foot level of the
Katherine mine, and there a crosscut
will be driven to the northeast con-
! tinuation of the Katherine vein.

J yield gold values as high as SO ton
The high grade character of the ore
exposed on all of the levels in the
Katherine mine, and more especially
the recent discovery Of high grade
ore on the 400-foot level, has served
to quicken mining effort at number
of properties, other than the Rather
inc Extension, which are reasonably
certain to carry northeast continual
ton of the Katherine vein At the
Gold Chain property, located approx
imately three miles from the Rather
inc mine. the shaft is nearing a cross
ledge, on its dip, which appears to
intersect the Katherin vein. Ait
drillers are eXpediting the work OF
shaft sinking. The Gold Chain cross
vein outcrops height of 200 feet and
is estimated to carry 100000 tons OF
brecciated quartz of an average val
ue OF Sc gold ton.
Cross Lodges Tested
At the Sunbeam CIV. J. Loring)
| property, adjoining the Cold Chain
on the north, a number of cross
lodges are being tested as a prelim-
mary to the installing of machinery
and the sinking of deep shaft. At
surface and shallow depth the lodges
on the Sunbeam carry gold values as
| high as 500 a ton. Nearby the Sun
beam property plant of machinery
| is being created on the Adams group.
| Upon completion of this work a new
| shaft will be sunk to develop the big
vein showing at surface. The cross
