NIXON NEVADA HAS
EXPOSED BIG
. DEPOSITS
OPENED RICH COPPER
ORE

mine which has produced some of
the richest copper ore ever mined
and marketed in carload lots, with
more of the same grade being hoist
ed daily. Owing to the limited time
the property has been operated, the
time required for installation of
pumps and machinery for handling
the water anu the comprehensive
plan of developing and proving the
veins at depth, the shipments of
high-grade have not been regular of
late, but enough has been done to
warrant the continued confidence of
the n in the future of the
mine.
OF II carloads of ore shipped
from the Nixon Nevada last summer
the smelter returns showed average
values Of 2S.47 per CEN copper and
$19.26 in gold and silver to the
ton. 1t will be noted that, in addi-
ton to the high copper value. the
ore carries gold and silver enough
to alone make it profitable.
In front of the superintendent Of
flee at the mine there is a "speci-
men, which came from the No. l
vein at a depth of 800 feet. 1t
weighs 919 pounds-which alone
proves a good width to the orebody
and averages nearly 70 per cent
copper. A piece broken from this
big specimen was analysed by a
well-known firm of San Francisco,
and its composition is shown to be
as follows: Copper, 70 2-3 per cent;
silver, 80 ounces; gold. one-fourth
ounce; sulphur, 1875 per cent; iron,
2k per cent; insolubles, 2k per
cent; no zinc or other penalizing
matter. A footnote adds: This
is almost pures chalcocite."
The outstanding feature of an
examination of the Nixon Nevada
mine is the great increase in the
kHSith of the veins and the value OF
Ne ore as depth is attained, seven
parallel veins, 100 to 200 feet
apart, show in surface outcrops Cd
the property, though some are very
small where they crop. Four of
these veins have so far been de-
veloped with splendid results.
The No. / vein is two inches wide
on the surface and has been de-
veloped to a depth Of 800 feet. At
this level the orebody is three feet
in width and the drifts have devel-
oped an ore-shoot 2S7 feet in length.
For the first 200 feet in the shaft
the ore averaged 19.47 per cent cop
per and $12.13 in gold and silver to
the ton. In the next 100 feet the
copper content increased five per
cent and there is Sc more gold and
silver to the ton.
Similar results have been
in the development Of the No. z
vein, and the ore now in n bin
is coming from the drifts along its
course on the 200-foot level. This
ore is sorted into two grades for
shipping and the best is said to
average 40 per cent copper, while
the second grade will go better
than 20 per cent.
The No. 3 vein has not been de-
veloped at depth as. when 1t was
penetrated by the cross-cut, a sud-
den flow of water delayed opera
tons, though samples taken show
c~alcocite and free gold.
1t is from vein No. a that most is
expected. This vein is two rect
wide where it crops, and the hillside
below it is covered with chunks OF
float which particularly impress
George w. Lloyd, the well-known
mining engineer. who has recently
gone over the property. A shaft
which opened up this vein at a
depth of SIS feet uncovered a pody
of ore four feet in width which as
sayed better than $50 to the ton.
The most important work going
ON at the mine at this time is the
extension of the cross-cut whlcn
will open up the No. 4 vein at a
depth of 500 feet on its dip. A mar
ubo has a fine record as a mine SUI
perintendent and who is known for
his conservatism. after a thorough
examination of the property, re-
marked: IF, when opened up IN
~, cross-cut, the No. 4 vein shows
as continuous improvement as it did
we're opened up in the 55-foot sha1t'
and as the first three veins have i'm
proved to the 300-foot level, then 1t
