eras are contemporaneous, the deduction
being based upon the recent discovery
of valuable deposits of the latter metal
at various points in the state. and at a
period when the wonderful gold strikes
in the desert country are astounding the
mining and investing public. Ely and
the newer camp of Greenwater are es-
sentially copper districts, the formation
in each instance indicating the presence
of large dykes Of the bronze colored
metal. In the Manhattan district. how
ever, with its many veins of high grade
gold ore, one hardly looks for the pres
ence of a metal of less rarity and value.
and yet there is a strong probability
that within a few years this section will
be as noted for it's yield of copper as for
Its output of gold. For some months
past a number of Manhattan mining
men have been engaged in searching for
copper in the East Manhattan district
and are meeting with success in their
efforts. They have prosecuted work
quietly and without attempt at publicity
and as the scene of their operations is
somewhat remote fro mthe main trails
little attention has been attracted to
their labors. Now that they nave de-
monstrated the existence of copper
veins of commercial value the full i'm
port of their research is announced for
the first time and there is every reason
to predict that it has a bearing upon
future mining operations in this section
equal in Importance with the discovery
of gold by Humphrey.
Two S~lavonians, Peter Ragoy end
Peter Bangier, located the acreage on
which the copper values are found,
later selling their holdings to Omer
Maris, F. T. Torpey, w. J. Stock, j. G.
McElvaney and Frank Humphrey, all
of whom are we'll known mining and
business men of this camp. These gen.
tlemen nave organized two companies
for exploitation of the territory, one
known as the Toquima Copper company
and the other as the Bonanza Copper
company. Each corporation is distinct
from the other in business affairs and
management, but will cooperate in the
erection and operation of a concentrat-
ing plant for the treatment of their ores.
The estimated cost of the plant is $780,
900 and negotiations for its purchase
are now on with a representative of the
Risdon Iron works of San Francisco.
The concentration is to be erected at the
site of the properties, and the repre-
sentative referred to agrees to have it
in working order within a sixmonth.
The location selected for the erection of
the plant affords plenty of room for the
distribution of tailings and a water sup
ply more than sufficient for milling
needs can be conserved with little
labor and expense.
Both properties have been examined
by ". o. Pray, a prominent California
mining expert, Ed Stuart, one of the
best known and most successful mining
engineers in Southern Nevada, George
Hopkins, a mining engineer of interna-
tional standing. and Grant Davis, until
recently consulting engineer for the
well known Copper Queen Mining COM
pany of Bisbee, Arizona. All -four gen.
tlemen are a unit in their estimate of
the value of the copper deposits cross
ing the estates and in the opinion hat
almost pure copper %sulphides will be
encountered at water level. Mr.. Davis
considers the East Manhattan copper
belt as good a copper showing as he has
ever seen during many years experience
in the mining field, and states that the
ore is identical in character with that
being mined in the great copper prop
critics of Bisbee and other Arizona
points.
The Bonanza company WINS four
claims paralleling each other and side
lining the acreage of the Toquima com
pany. The ledge crossing Toquima
ground passes across the width of the
Bonanza holdings giving the latter
company 2,4O0 feet of main vein matter
in which to work. The ledge is readily
traced by it's outcrop for fully a mile
across the two acreages and for nearly
the entire distance copper indications
are clearly in evidence. The lead at
surface has an average width of Z feet
and returns values in gold and silver
of s12 the ton and a copper assay OF 4
per cent. The ore is a copper ulphid
and of a character which permits of its
easy treamen by means of a concentra-
tor. For several weeks past mining eff
fort has been directed to proving up the
ledge at surface and is now being fol-
lowed by the sinking of a main working
shaft for the purpose of proving up the
deposit at depth.
Six claims are embraced in the acre

group being purchased by Mr.. Mauris
for $40, 900 cash. On two of the claims,
the Klondyke and the Alaska. the cop
per showing at surface is particularly
marked, copper blossom appearing
across the entire estate. An incline
shaft has followed the dip of the vein
matter on the Klondyke to a depth of
rs feet and in transit a zone was passed
through in which copper pyrites are
particularly pronounced. At present,
however, the bottom of the shaft is in
the leached zone, indicative of the near
ness of water level. Sinking is to con-
tinue until the flow is tapped when a
steam hosting plant and a pump cap
able of coping with the water are to be
installed. At a depth of 40 feet the
vein matter is about 10 feet wide and in
the bottom of the shaft what was
thought to be the hanging wall has dis
appeared. 1t is doubtful, however, If
the short crosscut run out at the 40
foot point really reached contact with
the true hanging wall as the formation
