The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1922-04-13


Lookout Mountain property Oh
Pine creek was placed in com
mission this week and movement
of ore from the mine to the loading
bins on the main road commenced. The
tram is of the gravity type, carrying
two buckets of 1000 pounds capacity
each. From the mine to the bins ore
is delivered in three minutes. A double
set of bins are in use at the foot OF
the hill, the upper section receiving the
ore from the buckets from where the
mill dirt is fed by gravity into the
three jigs installed on the middle plat
form, while the first class ore goes
through separate chutes into the lower
loading bin. From the jigs the ore is
fed into separate compartments in the
lower bin.
The jigs were started on Monday and
are yielding an excellent return, the
Lookout ore being well adapted to such
treatment Assays from the first re-
turns show the jigs to be making bet
ter than a 60 per cent lead product.
Each jig is turning out from 1 to
tons of concentrates per day, handling
both the sulphate and sulphide ore.
Three Rich Ore Shoots.
Development work in the mine is
keeping well ahead of the outside
equipment. The drift on the vein from
the No. crOsscut now shows ore from
tip to tip. measured in a straight line,
245 feet in length. In this drift three
extensive shoots of ore have been un
covered, the first, SO feet in length,
varying in width from IA inches of
clean shipping ore to over three feet
of milling ore. Twenty three feet of
carbonate ore connects this shoot with
the No. ? shoot which is continuous
for 65 feet with an average width Of
five feet This is mostly a sulphate
ore carrying from % to p per cent in
lead and with silver values varying J
from Is to "A ounces. A horizontal |
section of this shoot shows 800 square
feet of ore on the drift level.
East of the No. shoot the drift |
opened into a fine body of galena ore
According to Engineer c. f. o. Mer-
riam, from point 1S6 feet from the |
crosscut where the vein was first en-
up from six inches to 151a feet in the
center without exposing the hanging
wall Up to the present this shoot has
continued for over 40 feet Three feet
sampled by Mr. Merriam next to the
foot wall gave returns of AZ per cent
lead and the overhanging three feet
gave returns of 20 per cent. The re-
naming az feet is a high grade mill
feed. At this point the vein was cross
cut for SO feet with values obtained
across the entire distance. In the opin-
ion Of Mr. Merriam it is to be expected
that at depth below the teaching area
this width will produce profitable ore
Raising in Shipping Ore.
During the past week raise was
started from the footwall side and at
20 feet above the main drift was work.
ing in six feet of carbonate, galena,
and sulphate ores, practically all of it
being of clean, shipping grade. Some
beautiful specimens of crystallized lead
have been taken from this work. the
lead crystals in places being covered
with a green, copper tinge, reminding
old timers of the specimens taken from
the upper levels of the Tyler Sierra
Nevada and Bunker Hill properties.
Shipping to Bunker Hill.
Stopping operations are now under }
way and a steady stream of ore will s
be moved from the mine to the jigs I
and lower bins. The management will /
also continue the main drift to deter '
mine the extent of the No. shoot and I
make further exploration for additional {
ore bodies on the same level Fifteen I
men are employed at the property at S
the present time. Shipments to tile 2
Bunker Hill smelter will begin as soon {
as the roads will permit of heavy haul t
age, the ore to be hauled by means of '
auto trucks, distance of eight miles /
from the loading bins to the smelter.
