as soon as possible began the intelligent,
practical development of the Bunker
Hill claim, which claim lies on the
mountain side at the mouth of the gorge.
Under Mr.. Browns able and efficient
management the work on this claim has
been prosecuted with much vigor, and
the requirement of new ground of much
Importance to the future success of the
great concern under his control has been
looked after with the energy and bust
ness foresight SO characteristic of the
man. The country rock is gneiss, with
an occasional narrow porphyry streak
running through. but the ore bodies in
the Bunker Hill lie between gnelss walls
with here and there small streaks of
quartz. The ore bodies lie fiat and the
ore will average 215 feet in width, solid
throughout the entire present develop
ment, but there are several breaks or
faults in the vein, which was presumably
caused by volcanic action ages past; the
present workings being on the lower
backbone of a mountain and puncturing
the same by tunnel and drift from one
side to the other, finding good ore clear

On the southern slope Of the backbone

ore on the dump. At this point the vein
faults down few feet and then CON
tinues in waves, sometimes up and
sometimes down few feet, but every
where small prospecting drifts disclose
that it continues and retains it's average
width for 200 feet or more until the new
workings started from the opposite or
northern side of the mountain is reached,
which workings are of the systematic
miner-like sort. .."a
From the northern side of the noun
tain a drain tunnel was run in under the
vein distance of 245 feet. 1t is we'll
timbered and will of course drain the
mine. 1t is known as Tunnel No. l.
Tunnel No. 2 starts on the vein or the
northern side Of the mountain and is a
we'll tlmbered working tunnel, through
which most of the ore-even from the
other s1de-will probably be taken. In
this tunnel the ore body is of about the
same width as on the opposite side of the

mouth are drifts running each way from
the tunnel, IN both of which the ore body
continues without break. At lis feet
from the mouth of the tunnel drift was
started west right under the backbone
OF the mountain and following the vein
In this drift great depth will be attained
as the mountain is very high and steep.
1t is now in about los feet and the vein
is gradually widening, there being to
exceed 3 feet of solid ore in the face, and
SO far no break or fault has been en-
countered. In the tunnel following the
vein, a few feet beyond where the last
drift spoken Of was started, the vein
faulted up 30 feet, and an uprajse was
here made after it, but the tunnel was
continued on the ore body, which faulted
down to the tunnel level, and this puts
in sight at this point alone and ready to
stope about 200 square feet of ore with
an average width of 219 feet solid. In
the upraise the vein was found and

this drift, which is in about 12O feet,
good ore is disclosed all along without
break, and is gradually increasing in
width as the drift punctures the noun
tain, and there is about 81 feet of solid
ore in the face. =..z Em.=.
The whole mine bears evidence of the
fact that G.. B. Ballard, the foreman,
most thoroughly understands how to
work a flat or blanket vein to the best
advantage and in the most economical
way. He is without peer in this class
Of mining.
Having found the mine and developed |
it sufficiently to justify the erection of
works, the next thing for the owners to
is what sort of reduction works
are best suited for the working of the
property. Take the ore as whole and
it is undoubtedly base, or at least suf-
iciently base to preclude the probability
of the erection of a free gold mill The
writer is of the opinion that perhaps a
arge concentrating plant will be con-
'tructed in the early spring.
On another one of the claims-the
General Washington-there is tunnel
n 15O feet. This tunnel cuts through
7ein matter entirely, neither wall having
7et been encountered. The quartz is
porous and free, but as the vein is very
arge and all broken up, and while evi-
lently very large mlne, still, at the
present development, the ore would not
'ay to extract and sort. In this mine
he vein also faults up distance of
