CHEMEHUEWS HILLS
IS RICH IN COPPER
Engineers Report a High Grade
and Great Extent
of Vein

A report just made by Engineer c.
P. Topliff on property of the Yucca
Arizona copper claims to H. J. Haynes
& Sons of Los Angeles indicates that
the property is among the best in the
Chemehuevis mountains of the terri
tory.
A large gossan cropping is dwelt
upon at length by Mr. Topliff, he ad-
vancing the opinion that it is the cap
ping of an immense copper deposit.
An assay, according to the report, gave
returns of SIG in gold and silver and
$3.50 per cent copper, amounting to
over sos ton.
Text of the report follows:
Having examined the claims of the
Yucca Arizona Copper company at
three different times, extending over a
period of nine months time, I have de-
termined the following facts and the
consequent conclusions:
II find an immense gOssan cropping
on the claims, with an approximately
north and south strike. This Outcrop
as measured by Mr.. S J. Haynes and
myself showed solid for upward Of 300
feet in length and from 40 to rs feet
in width at either end of this outcrop
erosive debris has covered the vein to
some extent, although other strong
outcrops at either end for at least 1000
feet before it disappears under a noun
famous Gaping to the north.
This gossan cropping is manifestly
the Gaping to an immense copper de-
post. This is very apparent to the ex-
perienced eye, by reason of the porous
nature of the remaining iron, which
plainly denotes teaching of It's sulphide
content to have occurred. Proof of this
supposition is to be found On the
ground, for wherever an opening OF
any depth (oight or ten feet has been
effected both chalcopyrite and bornite'
copper sulphides have been found in
considerable quantities, as well as car
Donate and chalcOCite ores.
cat a considerable distance literally
from the iron gossan cropping are to
be seen numerous stringers of ore
striking directly toward the big out
crop, plainly significant of large pa
rent ore body.
OF GRANITE ORIGIN
1.-THE geological strata represented
show the country rock to be of granite
origin, probably a Sneiss, through
which igneous dykes have been thrust,
a condition which gives almost positive
promise of great depth of ore deposit
ton. such indication of permanence is
greatly strengthened by the position of
the vein; lying, as it does, near the
first upraise of the Chemehueyis noun
tains.
TT is a well established geological
fact that assures occurring near the
base line of mountainous upraises are
wedge shaped, and that the wider end
of the wedge extends downward.
Whereas, veins occurring at or near
the apex of mountain uplifts are also
wedge shaped, but with the point of
the wedge downward; and for such
reason the location can he counted as
distinctly favorable for large and con-
tinuous ore bodies.
''Of course you will realize that oW-
ing to lack of development, other than
nature has accomplished. it is impos-
sible to go into the minutiae Of geologt-
cal and neurological conditions, but
so much I can say, that there Is every
surface indication pointing to an i'm
mensely large and valuable deposit or
copper ore; in fact, l do not hesitate
to say that not only is it possible, but
distinctly probable, that intelligent eX-
ploration will prove this ground to
contain one Of the greatest copper
mines of the country.
"Furtber, while but the apex of the
deposit alone is visible, there Is but
little doubt that its underground rami-
ficatiOns are sure to carry it far out
side the lines Of its surface manifesto
lions; therefore a large portion of the
adjacent ground may, and some of it Is
sure to, develop ore Chutes. Therefore
it is advisable that a company taking
hold of this property should include as
much contiguous territory as possible
in order that others may not come in
and reap the reward which should in
ure to those who make the initial de-
velopment of this new field.
ASSAY RETURNS
Surface ores gave returns, accord
ing to James irving q Co, as follows,
from two assays: PHI single samples,
copper, 5.O4 per cent, $3.50, the low
est grade ore to be found on the prop
erty; second assay Of high grade ore
gave returns of $16.06 in gold and sill
yer and $3.50 per cent copper or sos 46
to the ton.
"The property is favorably situated,
about eighteen miles from the town oil
FranConia, on the main line of the SAN
ia Fe railroad and nearly connected
herewith by good wagon road. 1t Is
also but a short distance from the
Needles smelter which has recently
been purchased by the United States
and Refining company. The
is improving it and increas-
ing its capacity so as to be able to
handle 1900 tons a day.
"I believe the property will develop
deposits Of rich bOrnite ore, which
could be shipped to the Needles smelter
at a comparatively small cost.
"I am informed that there are two
small springs which go with the prop
erty, each about one mile distant from
the claims, with flow sufficient to
furnish the necessary water for mining
and domestic purposes,
I'm conclusion I will say that I know
of no more legitimate mining enter
prise offering for exploitation. nor any
which offers as great possibilities for
large returns on the necessary capital
it would take properly to develop these
claims, for 7 do not hesitate to say
that here is to be found a copper de-
