Many Deposits Not Worked

BY G. A. DUNCAN

The good work that is being
done by real estate operators OF
Las Vegas in proclaiming the e4-
mansion of area and increase on
population necessary to enable thus
coming city to meet the future
demands of its business activities,
now, naturally absorbs the atten-
ton of the public, and there Is
abundant assurance OF rapid
and extended increase Of popula-
ton here.
Quickly following the spreading
of information as to the advantage
of securing property here, however,
there should be set in motion
agencies tending to continued ex-
pansion and the sustenance OF the
increased population, for we must
produce things Of service II we
would hold prosperity.
It is entirely reasonable to as
sumo that our future proximity
to cheap horse power viii invite
many industries, but 1t is hardly
possible that any creative enter

or state, equal in general service
or wealth producing capacity to
that which Is going to develop
from the riches. in gold, silver,
lead, copper and the numerous
non-metalic deposits that exist
about Las Vegas, and tributary to
it.
Promising veins and deposits Of
metallic and non-metalic ores about
Las Vegas invite and warrant de-
velopment, but being acquainted
chiefly with El Dorado Mining
District, thirty seven miles south
of Las Vegas and twenty miles be-
low Boulder Damsite, I am moved
to express something of my belief,
which experience there has estab-
lished.
Not presuming to enter upon
| the genesis of ore deposits, I may
be pardoned for reminding readers
that among the reasons for the
existence of ore bodies, some are
purely of a mechanical nature.
| Whether metal values move about
| in the Earth'S crust in solutions
or vapors, it will be readily under
stood that these assembling and
distributing agencies worked along
channels of least resistance.
Roughly speaking, the process
of naturalization is as follows.
long circular or of devious type
Fractures of the Earth's crust,
give outlet for the bursting forth
of the molten interior Following
subsidence of such igneous activi-
ties, during the long period of
cooling there were repeated move
ments accompanied by grinding
and shrinkage of rock faces, the
result being that areas along the
line of fracture became less dense
than the surrounding country rock
so presenting channels for the col
lection and distribution to accom-
panying assures, of mineralized
solution and vapors, certain local
conditions setting UP chemical re-
actions which rob the vaporS and
solutions of their mineral content
so making ore deposits and mining
districts. Just this process and
condition enriched El Dorado Can
yon.
Occasionally the assembly OF
these conditions lacks one or more
of the most essential elements
necessary to the making of a COM
ercial valueable mine, and the
failure to detect and to be warned
off by such lacks, accounts for q
part of mining failures, misstat-
ments arising from ignorance, and
lying waste of opportunity through
bad management being other fire.
