the diffusion of values is so great that
it is difficult to find the concentration
necessary to make copper mining pro-
htable.

begins. or ends. in Carson valley, being
first discoverable in The Sierran granite
a short distance west from Genoa. Here
it is in the form of gray copper, with
surface showing of malachite. The veins
are frozen and narrow. but the values
are high and combined with gold and
silver showings. Northward the values
become dissipated. still entirely within
or in contact with granite. The zone
at Carson city extends from Lake
Tahoe on the west to Brunswick canyon
on the east. Whole hills here are
stained with copper sulphate and small
deposits of great richness are found.
The copper zone extends northward
through Washoe valley, showing on
either side, migrating on the westward
as far as Verdi.
The great phonolite and andecite bikes
just %northward from Reno seem to
have caused the copper values TO con-
centrate on the contact with granite
and s~yenite, giving higher values in
places than southwark from the con-
tact. A great center of naturalization
is Peavine mountain and it's n%eighbor,
Granite hill.
The copper now leaves the intrusive
dixie and escapes into the phorphyry,
showing remarkably strong in the Ante

shipping and Peavine has vast reserves
that could be smelted on the ground.
At the base of Dogskin mountain is
the new camp of Nashville, where the

is chalcopyrite, carbonate, bornite,
chrysoeolla, oxide, sulphide, ~sulphate,
even native copper and turquoise. Silver
and gold invariably accompany the red
metal and sometimes exceed 1t in pro-
portionate valu Shipments from
Nashville have been made for several
years and the Timetable property ON
Antelope is now in shape to begin send

From Nashville 1t is but a step to
Pyramid lake. where r. w. Parry and
associates have expended a large sum
of money in placing the ]. & X and
Crown Prince properties in readiness
for shipment or home treatment. Cup
rite is found in these properties on the
lower levels.
Thence the zone extends into and
crosses Humboldt county and is prac-
tically continuous. The elimination
seems to be reached in the Adelaide
mine in northern Lander, which prop
erty has been equipped with large
shelters at Golconda. Their type is
unsuited to the ores and no success
was made with the treatment. despite
the fact that the veins are nearly as
large and the values fully as high as
in the United Verde.
