Henry B. Clifford, the New York
CITY broker who is interested with W.
E. Renshaw and ass DC iates in the
Gem mine, arrived Wednesday morning
for a several days stay and to attend
to mining business in this and Sum-
NIT counties. The principal object OF
Mr.. Clfford's visit at this time is to in
spect the conditions in the workings OF
the Gem shaft, being sunk below the
level of the Newhouse tunnel.
The big 3-compartment shaft has
been sunk to depth OF 10
feet and quite recently the driving
of levels was started at the lOO-foot
point. The shaft follows the hang
ing wall and east drift is now in about
40 feet or almost directly 100 feet
under the line of the tunnel. At this
point a crosscut is being made to the
footwal where it is expected to cut
into the ore body opened up in the
Clifford winze. This ore body was
feet wide of pay ore, and part of it
carried values of $500 per ton. The
winze is 38 feet deep and the crosseut
will reach the streak at an additional
depth of 81 feet. Mr.. Clifford is anx-
ious to know whether this immense
ore body continues downward and car
ry as high values as in the Wine.
The outcome of this development
below the level of the Newhouse tunnel
and at depth of over 2, 100 feet below
the apex of the Gem veins, is awaited
with much interest by the mining men
of this district who have properties
intersected by the Newhouse, and will
have an important bearing on the sub
jects of secondary enrichment and the
continuity of values at great depths in
this district.
More than Is years ago the subject
was extensively discussed by mining
writer's and experts, and it was argued
that values did not go down to the depth
that would be reached by the then pro
iected, Newhouse tunnel At thaI
time the principal example cited by the
JneOrtlltdl "IIlClS anu ia4NA ~ 'N.'tN'
engineers, was the California shaft lu
Gilpin county which was sunk t9
depth Of 2, 240 feet But limited
amour of work was done in the bot

any ever found on on near the the sur

AS for high grade material at the
depth of the Newhouse tunnel those
who have kept posted know that thery

has been opened up which runs ll.s1

workings tellurium ore assaying more
than 100 ounces in gold, or worth over
81 a pound has been found; in the lat

owned by the Newhouse tunnel COMPANY
1O-inch streak of ore was opened
which ran 16.55 ounces in gold per ton,
and the company shipped more than
In the Saratoga lateral ore running 38
ounces in gold has been opened and in
the Hot Time lateral some exceptional
ly high grade mineral was found; in the
King Bee, Sun and Moon lateral and the
Silver Queen properties rich ore has
been disclosed, and the lateral develop
ment from the Newhouse tunnel is
not equal as yet, to the length of the
tunnel.
Mining experts are not agreed as to
whether the ore deposition in the
fissure veins was the result of as
cension or lateral secretion and both
theories have many adherents.
Neither were the experts all of one
opinion when Cripple Creek first puz-
zled the geologists. Disregarding
the engineers, the average mining man
goes on the logical basis that "gold is
where you find it, and they also ap-
preciate the fact that when it is found
at a depth of from a quarter to half
mile below the surface it is much hand
