THE phenomenal values and great
rapidity with which this region
has developed in less than two
years time have attracted great
attention, ELECTED many opinions, wise
and otherwise, and already obtained
The investment OF much capital in the
district In fact, the great majority of
the area of the territory Immediately
adjacent 10 the town of Goldheld in
the known mineral region covering
some thirty square miles or upward
has already passed from the owner
ship Of prOspectOrs and original loca-
tors into the hands of incorporated
mining companies in tracts ranging
from forty acres UP to as much as 800
acres.
Three classes of investors are operat-
ing in the district.
!. Those who acquire territory to-
tally irrespective of values. on which
10 organize mining companies and sell
out the stock as rapidly as possible TO
unlucky, unWary or innocent pur-
chasers. These are the promoters of
Wildcats and their victims are the
Lambs"
>. Those who place their properties
into mining companies and operate for
the purpose of making their profit in
the stock market, by the fluctuations
according TO the reports from the mine,
in the fashion Of the days of the old
-Comstock BOOM
3. Those who purchase properties
with a view 70 develop them into more
or less permanent mines. and who ex-
pect 10 make their profits from the
values extracted out of the property
itself These are the legitimate min
ing investors whom this article is in
tended TO assist, although of course it
may benefit also those OF the second
class. and be referred to even by those
first indicated
The region is an extensive volcanic
area characterized by the various lava
flows Of the rock types known as an
oeS1te and rhyolite, and intersected by
numerous dykes Of the same rocks,
also diabase and diorite- There is also
an intrusive granite Of the variety
known as alaskite, one carrying very
little mica but so far this has not
favorable to ore-deposits either by rea-
son Of its chemical composition, or by
reason of assuring.
The site OF the main volcanic neck.
chimney, or crater from which the va
r9ouS lava flows came has not feen
definitely located, but is indicated by
an extensive andeSite area near the
center OF the proved ore-bearing dis
trict This. however. shows no evil
the actual volcanic neck
The topography consists Of a number
OF low hills and ridges covering an
area roughly approximating sixteen
square miles. the ridges rising to
heights of 80 feet TO $50 feet above the
mean level Of the district, while the
hills rise to 300 to 500 feet in height
and those forming the general boun-
daries to the south and east rise to
prominences Of 500 feet to 1000 feet
above the average level
To the west Of the town the region
Is bounded by a line OF steep slopes
forming the escarpment OF an extern
sive mesa or table land. having an
elevation OF 800 feet to 400 feet above
the general level Of the town, and cap
ped by two fat lying lava flows of
andesitic and rhyolitic tufts.
Along the low ridges mentioned. and
the crests Of the lower hills are nu-
merous ouartzoSe outcrops standing
like walls or ramparts along the ridges
from five to thirty feet high above
the ground surface.
In certain belts, especially those
proved TO contain ore-bearing veins.
the ground is greatly discolored by red
iron stains, but this is not an in
variable sign of ore-bearing veins be-
low.
The main veins follow the course of
the silicihed ledges or dikes described
above, which have a general north
westerly or northerly course through
out the district, but which in places
are also found with an east and west
course, and IN one locality these sflici-
Gus dikes radtate from a prominence
known as the Black Butte, located
some FIVE miles northeast Of Goldfeld
and on which is one Of the best mines
IN the district. the Quartzite.
The origin Of the ore deposits was un-
doubtedly deeD seated. The hot wa
tiers came up the assures from below,
carrying various minerals in solution,
among them gold, a little silver. cop
per and some iron. As the waters rose
