! able. Ordinarily a dark blue gray
sane rock, in the faulted area of the
mines it is changed to a compact,
sparry, crystalline, white marbled
rock, losing it's bedding, original col
or, and structure, and except for its
Theological position would be I'M
recognizable.
The ore bearing zone is displaced
by the earlier east and west faults.
which, south of the Monte Cristo up
lifts have a down throw to the south
and north of it, a down throw to the
north. AS far as is known none of
the east and west faults pass into
the foot wall formation, and general
ly they are not very radical in their
throw.
There are two distinct classes of
ore deposits recognizable: First
those of Rocco Canyon, forming in
nearly horizontal beds, at or neal
the top of the dolomlte between the
assures; and second, those of King
Canyon, and northward, forming in
and along the main assures. The
assures, where not covered by alluvi-
UNI are traceable by following the
spongy iron gossan which fills them.
This gossan at the surface carries
from 4 to Is ounces in silver per ton
and occasional boulders of lead car
Donate and gelena, varying in size
from a few pounds to masses of
several tons weight. The lead Is
found in the gossan as if it had been
left stranded by the teaching process
which has oxidized the iron. At no
point has the sulphide zone been
reached to determine the nature and
value of the ores at a permanent
water level. In the King and Peter
son mines depths of $50 and 105 feet,
respectively, have been attained
neither of which has reached the sui
phide zone. These are the two deep
est mines on the east fissure. On
the west assure, in the McEllin mine
a depth of 500 feet by tunnel has
been attained with the same result.
1t has been thought by many that
the silver mines of Treasure Hill
were shallow deposits and this opin-
ion is entertained by a few regard
ing the bedded ores of Rocco Canyon,
but all authorities agree that the
lead belt assures descend to I'M
known great depths.
At present the active mines along
the belt, naming them from the south
northward, are as follows: Great
Valley, Rocco Homestake company,
White Pine Lead company, Nevada
Lead company, Cornell, McEllin, Car
Donate King company, La Ben Gala,
Peterson and Coyote.
The production from the lead belt
to date has been las, 900 tons, aver
aging 65 per cent lead and 20 ounces
silver per ton, having a gross value
of nearly s 100000. In this produc-
ton it should be borne in mind that
little, II any, capital other than that
taken from the mines has been ex-
pended in their development, and
that only the highest grade pres have
been profitable. That where there
mines exceed 100 feet in depth their
ores have paid for the deeper work
ings, and that many comfortable for
tunes have been awarded to leasers,
individuals and companies by their
operation.
Recently a railroad company has
been organized to build a line from
Ely to Goldfield. If it crosses the
White Pine range at the most
feasible place, Little Antelope Pass,
1t will run within eight miles of
Hamilton, which will make it
possible to market ores of a lower
grade thar have hitherto been
profitable and enormously increase
the output of the district.
