Marysvale Utah, Sept. s.-A recent
roundup of rumored strikes from the
mineral area west of MarysvaIe and a per
sonal examination of conditions at the
several points of mining activity. have
more than verified the truth Of the ru-
mOrs. In one instance the exposure of
ore Is weli-nigh staggering and had il
been made at any point within 100 miles
of Salt Lake City the news of it would
have created a stampede But a STAN
pede is not desirable. All we ask is
healthy growth and increased confidence
in this country. by which many of US
have stood during more than a quarter
ceBtury.
Wall Of GoId-5earing ouartzite.
Some twenty-six years ago a Mr.. Shell
lon discovered the CLYDE lode in Cotton
wood canyon about ten miles southwest
four feet thick and about eight feet high
yielded ore running more than $500 in gold
per ton. Shelton sold the find for 5000
spot cash TO some Chicago men, who or
ganized the Pluto Mining. Milling &
Smelling company. A 200-fOOt tunnel was
run on the vein and from q point about
100 feet from the portal a shaft was sent
down to a depth of about eighty feet.
Signs OF copper were plentiful but a per-
manent body was not discovered. With
that child-lil1e and bland confidence in
tain point, an assumption that has
wrecked so many promising prospects, the
Pluto company drove tunnel from the
creek into the hill distance of nearly
LOO feet The first 800 feet of the tunnel
went straight for a point some 400 feet
beneath the bottom OF the eighty-foot
shaft. The face of the tunnel was in
nearly vertical limestone which contained
an easily worked stratum about four and
a half feet Wide-just the width for nice
prospecting tunnel Thus it came to pass
49, 4
odd degrees to the right and the soft
stratum followed some 1850 feet and is
still in limestone
Jennings Gets the Copper.
Some four months since Isaac Jennings
of Salt Lake and one of the Pluto com
pany, built a platform about twenty feet
down in the shaft before mentioned, and
began drifting 10 the west. Within foot
or two he encountered pay copper, which
has continued to increase in size and val
ne with every shot The dip of the shoot
was a guide, and Mr.. Jennings went down
the shaft another twenty feet and has
opened up a mass of copper ore that is
simply a marvel The shoot is some
twenty feet thick, ten feet of which is
almost pure copper glance, and is aSso-
cated with lesser quantities of nearly
every kind Of copper ore known to min
eralogy.
The ore lies in a nearly white and high
y altered pOrphyry and is dipping to-
ward the quaTtZite lime and pOrphyry

favorable position at the intersection Of

Secondary Enrichment Jokes"
The history Of the Clyde has been writ
ten as an illustration of the many mis-
takes in mining, and of the fact that ma
tUre is entirely regardless Of any and all
expert opinions as to where ore bodies
should be found at depth.
The secondary enrichment of veins is
joke often (uncOnsciOusly of Counsel,
played by Dame Nature on the unsuspect-
ing prOspector who is lifted into the
clouds by rich groupings, and descends to
terra firma with dull. sickening thud''
when he discovers that the values are
slowly and surely retreating.
The secondary enrichment joke was
played TO a finish on the owners of the
Dalton and Wedge properties of this To-
cality, and has been yerttable hoodoo
TO the camp. There is, however. not a
doubt that If 1.-THE of the nerve sXhib-
tied by investors in Colorado and Nevada
were applied to the great vein Of the Dali
ton that the lsached and semi-barren zone
would soon be passed and that good val
ues would be found in the unaltered sui
phides that surely exist at no great depth
Two Mineral Belts.
There are two distinct belts of miner
alization along the east slope of the Mount
Raldy range Along the east front of the
range, and we'll back into the mountains.
oxides and chlorides are predominant and
the surface values are generally large.
This belt represents the area of secondary
enrichment Up near the crest of the
range, almost within rifle shot Of lofty
BeIknap and Badly, il found the sulphide
belt which was only recently discovered.
The basic rocks Of the lower belt are
ouartZite and limestone and are stipend
ously fauited and tilted. Along the lines
of faulting and the contacts of the basic
formations intrusions of monzonite, rhyo-
lite and other eruptions appear as dykes,
belts and overflows. And II Is signifi-
cant that such mines as the Webster
Deer Trail and Clyde are found along the
lines of greatest faultinB-
Similar TO Bingham.
The student of the geological conditions
of Bingham canyon and OF MRTysvale, re-
spectively will note a striking similarity,
and the recent discoveries Of copper in
the lower belt, as IN the Clyde. for in
stance would seem to indicate that, like
Bingham, copper win be the deeper seat
ed metal.
The country rock OF the upper or sui
phide belt Is composed exclusively of erup-
lives A great belt of irOn-stained mon
zOnite parallels the crest of the range, is
completely faulted. and wherever exposed,
presents the significant vertical structure
The crest of the range is marked by
great dyke of phonOlite several miles IN
length.
