Colorado.
There is mine boom on at Empire
and everything is looking prosperous.
A strike of importance has been
made on Ironclad hill. Cripple Creek,
by lessee Frank Galley. Assays give
high values.
The various parts of the Little Mat
tie mine at Idaho Springs, are looking
unusually good and the prospects are
bright for a prosperous winter season.
Development at the American Sis
ters mine at Georgetown, is again in
full swing after a close-down of three
years. Machine drills have been
brought into commission.
R. G. Buffers, assistant state geol-
ogist, has been investigating the new
mineral springs just found near Love,
on the Beaver ranch, within five miles
of Cripple Creek and said to contain
wonderful medicinal properties.
The early installation of the Motter
process of ore reduction Is now ap-
parently assured at Idaho Springs. The
preliminary work of clearing the old
Idaho reduction works building is now
men and the new machinery will be
shipped at an early date.
The Orpha MD mine, on Bull hill.
one of the first discovered in the
Cripple Creek district and now owned
by the Stratton estate, has been start
ed by J. H. White & Co. of Colorado
City and the first shipment made of
ore from new prospect on the bot
tom lever, which looks well.
Louis Chari, leasing on the Com
monwealth mine in East Argentine.
has with in the past five months
shipped nearly 100 tons of smelling ore
that averages $40 per ton in silver and
lead. Stopping is in progress on body
of solid ore twelve to eighteen inches
wide and heavy tonnage will be bro
| ken.
Work has been resumed on the
Ohio group Of claims, situated on Kel-
so mountain, West Argentine district.
1t has been decided to start a new
crosscut tunnel closer to the base Of
the mountain than the old workings.
but within a comparatively short dis
tance the veins will be intersectec at
fair depth.
Men have been put at work on the
upper levels of the American Sisters.
at Georgetown, where large bodies OF
| high, medium and low grade ore are
| showing. In the bottom of the shaft a
streak fourteen inches wide is exposed
that assays as high as 365 ounces silver
and 1.5O ounces gold per ton, with Il
per cent lead.
On the Seven-Thirty property.
Georgetown, body of ore from ten
to fourteen inches wide is showing in
the ground being operated under lease
by Jas. Woods that brings a mill set
tlement of 700 ounces in silver to the
ton. This lessee has been at work on
the property since January 1st, but
the workings are now in shape where
by steady tonnage OF ore will be
mined.
One of the most important events
in the mining industry is taking place
at the Mccormick mill up Chicago
creek, Idaho Springs. where A. w.
Dowd & Co. are putting in the new
process known as the Johnson method.
using chemicals and electricity for the
extraction of all metals contained in
the rock. Some excellent tests have
| been made with very satisfactory re-
suits. sufficient to insure radical
change from the present way of treat
ing our ores by smelling.
An enthusiastic meeting of mining
men was held at the court house in
Leadville for the purpose of listening
to proposition from the Central Colo
RADIO Power Company to unwater the
several square miles of territory in the
heart OF that mining district. Four
years ago, when the pumping opera.
tions ceased in the downtown district,
ar immense area was flooded and rem
dered inaccessible to further explora-
| ton work.
new chemical process for extrac.
tion of copper from complex ores has
been developed by J. C. Clancy, the
metallurgist who invented the process
| for extraction of gold which will be
used in the Colburn mill at Cripple
| Creek. The copper process was worked
out by the inventor during his stay
in London the last few months and he
has secured patent. 1t promises to
revolutionize the copper metallurgy Of
the world II 1t proves all that Is
claimed for 1t. 1t is designed to treat
the great undeveloped bodies OF gold
ore containing small percentage of
copper, which are found in every part
OF the world, and which cannot now
be treated at profit by any known
process.
The Cresson mine, Cripple Creek,
has granted lease on the dumps to
local and Denver parties who contom.
