Last week The Miner reprinted
from the Denver Mining Record an
account of the wonderful gold strike
made in the Cresson mine at Cripple
Creek recently. Since that was pub
lished the strike has been visited by
representatives of the Colorado school
Of mines, and while their report is a
little more conservative. the strike
still stands as one of the most re-
markable ever made in the west Of
the inspection by the school of mines
men, the Mining Record says:
Professor VOLTS Statement.
/ Prof. Horace B. Patton, geologist
at the Colorado School of Mines, and
Professor Harry j. Wolf, at the head
of the department of mining, visited
the great Cresson ore strike at Grip
pie Creek a few days ago. The result
of this joint examination will appear
in the next issue of the School of
Mines Quarterly. Professor Wolf
briefs his observations as follows
Ion December Is I had an oppor-
tunity to examine the recent rich
strike in the Cresson mine at Cripple
Creek This discovery is of special in
terest to the mining public because 1t
tends to justify confidence in the fav-
orable possibilities of deep level devel-
opment in the Cripple Creek district.
:" In view of other deep level devel-
opments in the neighborhood, such as
those in the lower levels of the Vindi,
Gator and Golden Cycle properties on
the other side of Bull hill from the
Cresson mine, it is reasonable to sup
pose that the Cresson strike will
greatly stimulate speculation in deep
er development of many properties.
The discovery which has attracted
special attention at this time was
made about November Is in the
twelfth level of the Cresson mine at
depth of 1865 feet below the surface
A chute which was being driven from
one of the eros suts in the ore body
on this level broke into the side Of q
pear-shaped chamber about IA feet
wide, % feet long and SO feet high
This chamber was found to be about
tWothlrds full of loose material, and
very much resembled a stope filled
with broken ore.
What Cavern Contained.
"'The filing consisted of fragments
of breccia. encrustod with quartz and
strontianite crystals, and more or less
cemented together, most of which
could be mined with a pick The in
crustations were thickly sprinkled with
tabular crystals of sylvanite and Gala
verite, some of which were more than
three quarters Of an inch long, and
many Of them presented a face having
an area Of half square inch. The
breceia itself was permeated with
sylvanite crystals
The filling included several irreg-
ular deposits Of white, crumbly mater
ial, probably strontianite thickly i'm
with crystals of sylvanite
This material was the richest orc
found and assayed from 10000 to
$1,000 ton. Such material, together
with fragments of ore having promin-
ent incrustations of telluride miner
ais, was carefully sacked in the Slope
The balance of the ore was shoveled
over 1-inch screen, the fines from
which assayed about $4,000 to $4,000 Q
ton, and the oversize had a value
from $1,000 to $500 ton.
Half Million in Sight.
"'At the time of my visit the ma
terial in sacks might be conservatively
estimated to have net value of about
$250000 The ore remaining in tho
and around the walls thereof
could be safely estimated at another
s250,000 The total profit in sight
amounted to not less thar
100000
" In view of the fact that the extern
Of the rich ore has not yet been de.
termined, 1t is probable that a sub.
staAtial increase in this estimate may
be justified by further development
The deposit will soon be further pros
pected by a crosscut designed to tar
the possible downward extension Of
the chamber at a depth of about 81
feet below the twelfth level. This
development may result in further
startling disclosures.
""The rich chamber of bonanza orc
occurs in the midst of large ore shoo'
which is about 500 feet long and has
a maximum width of $50 feet on thu
twelfth level The ore in this shoot
which has been payable from a point
above the sixth level, has a value that
varies between 500 and $40 ton. The
ore body is wider and richer on the
twelfth level than on any of the lev.
