The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1920-10-28

NNOU NOEMENI was nldut
~ through this paper several
/ ~ months ago that the Bunker
Hin & Sullivan company was
engaged in making extensive labora-
tory tests for the purpose of finding
a successful treatment process for the
complex zinc-lead ores of Pine creek.
This experimental work is still going
on under the direction of some of the
foremost metallurgists and chemists
OF the country. 1t was officially stat
ed some time ago that very encour-
aging results have been achieved, JUS
tifying the expectation that the prob
lem will be solved and a commercial
process evolved that will prove of in
estimable value to the zinc mining in
dustry The ore used in these ex-
perments is from the Constitution
mine, on Pine creek, and according to
current report without official infor-
nation, the Bunker Hill & Sullivan
company owns control of the Consti-
tuition company. But whether that is
true or not the experiments being
conducted are primarily for the pur-
pose of finding a practical process for
the treatment of Pine creek ores, and
if successful it will result immedi-
ately in placing Pine creek ION the
map" as a great mineral producing
section of the Occur d'Alene district.
There is no question regarding the
amount of ore; it is there IN numer-
GUS properties and only awaits the
development of a process that will
permit mining it at profit.
Nevada Stewart.
In spite of handicaps that have
held the section back. work contin-
ues on Pine creek that indicates con-
fdence in ultimate success. A strike
of considerable Importance was re-
ported yesterday on the Nevada
Stewart, joining the Highland Sur
prise on the west In the upper tun-
mel of the property the vein is large
and is mostly composed of iron,
quartz and other vein materials also
little lead, but no zinc. Another
tunnel has been run about so feet
below and while doing assessment
work a splendid showing of ore was
disclosed in the face. This showing
is seven or eight feet wide and has
stringers of lead-zinc ore all through
it. In one place there is about Is
inches of almost solid ore The ore is
different than the usual Pine creek
ore in that it is coarse grained and
easy to separate by con-
centration Samples of the ore were
exhibited in this city yesterday by
NJ J. Sinclair. manager of the com
pany.
Highland Surprise.
Mr. Sinclair is also manager of the
Surprise company and stat
ed that he had been engaged during
the past few weeks in getting the
mine and mill in shape for operation,
conditions are such that no
will be made to operate at
this time The bins are full of ore
and much ore is available in the
slopes. In one stope particularly Mr..
Sinclair said there is a solid block of
ore 200 feet long, from two to four
feet thick and with a back of go feet.
The trouble with the Highland Sur
prise is the same that prevails at
other Pine creek properties, the com
pick character of much of the ore
making it impossible to treat it
through the usual concentrating and
smelling methods.
Douglas Lease.
The Douglas Mining company has
leased the ground above and below
the Marmion tunnel to Hugh McGilhs
and D. J. Mcdonald, who expected to
start work yesterday. The Marmion
tunnel is on the opposite side of the
canyon from the main Douglas work
ngs. The tunnel has been driven on
The vein for a distance of between $50
and 300 feet showing a continuous
shoot of ore averaging about a foot
wide, containing both lead and zinc,
the former predominating. The leas-
ers will stope the ore already avail
able and also sink, the indications
being that the ore shoot widens with
depth.
