Butte, May 3.--Angelica Mining COM
pany, controlled by Duluth interests, OPP
Grating the Mount Washington mine near
Wickes, Mont, has opened an ore body
II feet wide on the 7O0-foot level, ac-
cording to adyices which have been re-
ceived in Butte.
The disclosure is regarded as one OF
the most important in the WickesCo
bin district for a number Of years and
it is of especial significance in working
out the faulting system of the Mount
Washington property, definitely estab
fishing the throw Of the ore shoot to the
southwest of the faulted section of the
mine, the deposit being picked up in
about 400 feet Of crosscutting.
ASSAYS across the face Of the ore
body show 80 per cent lead, 3T5 ounces
Of silver and $6 gold
The deepest level Of the Mount Wash
ington is the 500 and crosscutting is in
progress here to pick UP the downward
extension of the ore body and if the
projection Of the dip Of the shoot is
correct, the deposit should be reached
within the course of about 200 feet of
prosecuting.
The Mount Washington has been a
shipper for the East Helena plant Of the
American Smelling & Refining company
for some time, considerable tonnage Of
ore having been developed upon the up
per levels.
Butte D uuth.
Leading bondholders If the Butte
Duluth Copper company have agreed to
waive the interest due some time ago on
the bonds, which payment was to have
been made by the Mines Operating COM
tal.
der a long term lease, but at the pres
ent time has suspended operations pend
ing an improvement in the copper metal
market. 1t is planned Immediately to
resume operations once the price of
copper permits Of profit being made on
Butte-Duluth ore, which should be, it
is estimated, in the neighborhood of
20 cent per pound MetalIurgists of the
Washoe works of the Anaconda Copper
Mining Company have successfully evol-
we'd a process for the sulphuric acid
teaching of the Butte Duluth ores, which
are Of n highly silicious~ character.
Further development of the Butte
Duluth property has uncovered a ton
mage averaging somewhat higher than
the general run Of the ore heretofore
and the content Is ranging around 1T
per cent copper, as compared with IA
before. Butte-Duluth has an estimated
tonnage of 20,000OO0, according to Capt.
A. B. Wolvin, Of Duluth, who floated
the company.
The Mines Operating company has de-
signed considerable number Of surface
improvements calculated materially to
reduce the cost of handling the rock,
which is crushed on the ground. con-
nection will be established with the
Butte Bullwhacker property adjoining,
which is controlled by interests which
make up the Mines Operating company,
and thru a crosscut and over a trestIe,
an electric tram viii be installed, per-
Initting Of the establishment Of COM
mon crushing plant for the Butte-D
luth and the Butte BuIiwhacker, in ad-
dition to a common loading station for
both concerns This will result in saw
ing the pay Of about eight men.
Anaconda Company.
The Anaconda Copper Mining com
pany has devoted considerable expert
mentation to the treatment of Butte
silicious ores, ad the only factor re-
naming before the Anaconda embarks
on the general treatment Of such ores
is a more economical manufacture of
sulphuric acid. At the present time the
engineers of the copper corporation are
experimenting with the manufacture Of
the acid by process which occupies
approximately one-tenth Of the present
