Lee Mantle.

"what about the big strike in the
Olive Branch which Is being operated
by your company" queried reporter OF
the Inter Mountain of President Lee
Mantle of the Butte Mining & Develop
ment company today.
"There has been no strike in the Olive
Branch that I am aware of as yet" re-

the sinking Of the additional 100 feet.
making the shaft 200 feet deep, and
are now prosecuting both ways from
the bottom Of the shaft for the pur-
pose Of cutting the leads which are sup
posed to exist on either side.

to find q continuation of the rich ore
which was found above at the 10O-foot
level.

ct the Olive Branch, published in the
morning papers, was simply rich piece

I'm a few days the lead will be cut
and we shall know what we have at

"IIow are developments at the Emma
progressing?" asked the reporter.
Progress at the Emma has been ex-
ceedingly slow and difficult for the past
three months, owing to the unfavorable
character Of the ground, and the large
volume of water encountered.
1.-THE shaft ran into what was almost
q bed Of Quicksand Is feet thick lying
next the footwall. For two months the
safety Of the shaft was constantly en-
dangered and the entire mining force
was engaged in the effort to protect and
save It.
"Under the supervision and direction Of
Superintendent A. e. Spriggs and George
H. Robinson the conditions in the mine
and surrounding the shaft have been

sion is felt.
Water Pressure Reduced.
''The vast lead has been drained to a
great extent so that the water pres
sure is much reduced and the shaft has
finally been carried through the mov-
ing ground and Is now about to enter
the country rock on the footwan OF

a satisfactory manner.

the pressure off the shaft a crosscut
