One OF the many great mines now being
developed in Butte Unknown as the Harris
Lloyd tunnel, owned by the Boston &
Montana Copper Mining company. The
property il situated southeast OF the st.
Lawrence, and takes it's name from the
fact that John K. Lloyd and the Harris
brothers owned it before the Boston q
Montana bought out their interests, which
was SOM time in September, 1888. While
the property was in possession OF Harris
d Lloyd a tunnel LAB feet in length was
run into the hill, but nothing except OK
odissd ledge matter was struck. After the
tunnsl had been finished a shaft was sunk
to the depth Of 200 feet near the mouth Of
the tunnel. This shaft cut through a 40
foot ledge OF oxodixed matter, which con-
tanned both copper and silver. After the
shaft had reached a depth OF 200 feet, the
property was sold TO the Boston q Mon.
tana for $685. 900. This company COM
menced immediately to sink the shaft
still deeper, but after reaching q depth OF
400 feet sinking had 60 be abandoned on |
account Of inadequate hosting machinery.
This, however, did not deter the company
from developing above, and crosscuts were I
run south from the 200 and 3OO.foot
levels. At q distance OF about 40 feet
from the shaft Of the former
the ledge was struck and a levs,
then driven east on the vein, which at
that depth proved to be solid copper ore
carrying considerable silver. This level is
now in about 400 feet. At the 3OO-foot
level 65 feet OF prosecuting had to
be done before the ledge was en-
countered, but at that depth it
proved to be even richer and wider than at
the one above. A 400-foot level was also
run east ON the vein at this depth, and
some OF the ore stopped out near tbs last
end. The ledge on both OF tn" e I. vef- ~
about 80 feet wide, but e,ra.ks Of rich
ore ext-n "a, t.,to The wo.is. Between the
goo and 300 iJpt levels, in the east end, 4
an air si14fE has been sunk through solid Fl
ore, and 1t rs at the bottom Of this shaft
that the ore has been stopped out to q
height OF three floors. Il
1t is q difficult matter to form q correct /
estimate OF the amount OF ore now in i
sight ut the mine, but it is up in the hun
dreds OF thousands OF tons. Like the /,

Boston and Montana, the Harris. Lloyd =
property is only being put in shape for :
working to advantage when the company =
will have built it's smeltery at Great Falls. :
and then only, will the truly great =
OF these properties be known. It /.
thought that at least 100000 tons OF !
Ore are in sight at the Harris.Lloyd alone,
Which, figured up, would be worth about
e23, 200 900. These figures are based on
she present. price Of copper and silver, but T..
IhoGld either or both increase in value, the a
Inference must be added.
Excepting the tunnel, no work has been
lone either west or north of the old shaft.
IN the 40O-ioot level O crosscut has been q
about 20 feet soI.th, but no work OF w
will be done there until the .,
hoist is placed in position at the new u
bait, which is now down $50 feet. The a.

OF the new shaft. As soon as this de

January or February, as it will take un- ms
that time to put the new hoist in posi-. tn
