Mines and Mining Stocks
WEBER THEORY
WELL RECEIVED
WondrouS Possibilities of the
Colorado Sioux Zone Are
Conceded.

The new theory of ore occurrence on
the Colorado-Sioux zone-that the ore beds
are following the dip of the western arm
of the great synclmal fold, with the
natural inference that they will continue
TO make around the near half-circle-was
well received yesterday by the mining fra
ternity, disinclined as mining experts usu-
ally are to accept new theories. Some
of these, in fact, confessed to being in
the position of the gentleman of Celtic
origin who said that he had been re-
minded of something he had never
thought Of. few probably, had con-
sidered the possibility of such occurrence,
but the new developments in the Sioux
mine were required to inspire one with
the daring necessary to prOmulgate il.
Sioux Consolidated has been breaking
into new ore beds. above and below the
main body originally opened on the 400
level, until between the limits of ore on
the west and on the east is a distance
of more thar 300 feet. And everything
Is dipping east and southeast. In add
ton to this is the significant fact that
the ore body in the Colorado mine, only
400 feet north of the SiOuXs north line,
is at least $50 feet above the SiouX's 400
level. Which presents the prospect of an
other bed being found in Sioux above the
one on the 400 level.
Absence of Fissure Puzzled.
The Colorado Sioux ore zone has long
been a puzzleI to mining experts. In all
of the other zones of the TintC district,
in which more extensive prospecting has
been done, the ore bodies extend to great
depth, the formation is cut by deep fiS-
sureS, through which the Ore-making so
buttons have assembled, to make into beds
where they have encountered the right
kind of lime.
Naturally. it has been presumed that
the ore beds opened for several thousand
feet on a nOTJheTly and sOutheTly strike
on the Colorado Sioux zone were formed
hoo At nod
that there must be a fissure there and
that il would be found almost directly
underneath the beds which have been
opened at intervals upon a general strike,
even though their planes do not always
correspond.
But the situeuon of the Colorado Sioux
zone is different from that of any of the
others Ii is upon the slOping edge Of
the trough formed by the giant synclinal
fold, while the Otners-thOse upon which
the older mines of the camp have
been opened-are back upon the uptilted
ends of the formation, as it were.
Something to Conjure With.
The possibilities of that trough are
something TO COniure with. IL is al
together probable that the stratum Of
lime in which the COlOTadO-SiOuX ore beds
are made follows the semiCircle which the
fold describes on the eastern side of
GOdiva mountain That the beds are
dipping in conformity with the line of
the fold. and that no fissuTe has vet been
found TO account for the ore deposits.
provides ground for the belief that the
source of the ore is farther east-that
il may be in the bottom of the trough
Should it prove TO be true that such
great ore bodies as those in Colorado.
Sioux and Iron Blossom, so far up the
side of the trough, have ascelded the
distance indicated. the question arises
What will be the limits in size and rich
ness of the ore bodies to be found nearer
their source
