is not yet sufficient to settle this ques-
ton on a scientific basis.
As stated in the beginning of this arti-
Gle, the main question is whether this is
a good, permanent, profitable field for
mining investments, and in reference to
these points | have reached the follow
ing conclusions.
First-The district comprises a series
OF parallel vein zones. The Combination,
Florence, Juhbo, Red Top, Velvet, st.
Ives may be taken as a typical example.
There are six of these zones indicated by
the discoveries already made, but the
developments are insufficient as yet to
accuracy. There appears good reason to
believe that this parallel vein system
extends considerably east OF the district
shown upon Chute's map, and may eve
extend under the surface of the desert
to the northeast, and south. Perhaps
also under the mesas to the west, into

district.
Second-The proved area OF valuable
territory in the vicinity OF Goldtield and
to the eastward consists of sc square
miles within which these vein zones are
proved to exist, but the productive
mines thus far are within an area of II
,,,,r, ,,;lac Thora ic NO raavop for
doubling that energetic and wise de-
velopment will eventually prove the
acreage value OF the greater part of the
IS square miles, but little less than that
of the central IA square miles.
Third-The payable mines are not to
be confined to any rim or horseshoe of
valuable territory surrounding a central
region OF poor or worthless ground. 1t
so happens that discoveries have been
made at many points which when joined
together by an arbitrary line forms
roughly the shape OF a horseshoe, but
some of these mines are actually upon
different vein zones from the others and
separated therefrom by belts Of poor or
barren territory. For example, the
Dixie, Snowdrift and Empire are on a
different zone from the January, Combi-
nation and Florence, and all of these in
no manner connected with the Vernal,
Quartzite system.
Fourth-The logical conclusion from
the above facts is that the central pOr-
ton of the district should, within the
limits of the various vein zones, yield as
we'll as the mines in the outer portions
of these zones and as the developments
are carried forward, this is being proved
notice especially the locations OF the
Simmerone fraction, Lone Star and EN-
pire.
posing the quartz ore dykes or reefs are
naturally the most favored places for
prospecting, and those likely to produce
results the soonest because surface de-
bris is the least, yet the flats or gently
undulating territory should not be neg
lected, as there is no reason to doubt
the continuance of the veins lengthwise
through this class of ground as well as
the hills.
Sixth-Ore bodies are generally found
at the intersection OF veins. Frequently,
the intersecting assures or crevices are
much smaller than the main vein, but
the result has been to check the flow
long enough to enable strong impregna'
ton and good deposit of ore, the aver
age of the district being exceptionally
high in value, as is we'll known. While
the ore shoots are short on the length of
the vein Il believe no shoot has been
proved longer than 200 feet and most
are much less. the width in the center
is frequently 10 to 20 feet and over, and
the exceptionally high grade makes the
net proceeds in dollars considerable.
Seventh-Continuity in quantity and
values is we'll proved in depth in the
Combination and Florence, both Of
which are in unoxidized or live ore, the
former proved to $50 feet in depth. The
veins as they are developed deeper in
the live zone show much more regular
ity in form and course than in the oxi-
died zone above, and the increasing
percentage of copper in the live ore
gives good promise Of permanent high
grade gold values as greater depth is
attained. There is no reason to doubt
that the veins of this district can be
profitably mined as deep as mechanical
appliances will allow. 1t is true that in
sinking, miners have frequently lost
their ore,' but this is often due TO IL
OF two reasons. either the ore body was
one of the smaller pockets or lenses SC
frequent in the oxidized portion Of the
veins or the ore shoot pitched out of the
shaft unobserved by the operator and
can be recovered by drifting.
Eighth-It has been customary to
compare this district with Cripple Creek,
