The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1913-02-27

Our abortive federal apex law has
been the cause of more grevious hare
feelings and expensive litigation ant
interruption of the mining industry In
the Occur d'Alenos than any Other
single cause and every mining man
should get busy and urge the revision
of this and other silly mining statutes
by which dur mineral industry is now
embarrassed for the benefit of future
locations and ore discoveries.
Marsh Mine.
At Burke the notable development
progress Of the year has been mark
ed, Improvement of the interesting ore
channel now being opened by the
Marsh Mining company east of the III
ger Poorman.
This interesting ore body has now
been followed through an incline shaft
sunk from a crosscut tunnel driven in
from the gulch to a further vertical
depth of 400 feet. and has shown Il
marked expansion in both width and
length as the development has pro-
crossed downward
1t now has an ore body over 300
feet long with maximum width of
10 feet of excellent milling grade that
made an output during the year of &C
cars of mineral containing nearly g.
100000 pounds of lead and $1,000
ounces of silver and 100 ounces Of gold.
This ore is hauled from Burke to
the Pittsburg company mill on Nine
Mile for treatment. The Marsh COM
pany is now pushing new scheme of
development involving the raising and
sinking of a vertical shaft from the
lower level for the purpose of a more
convenient methof developing and
handling the manifostly important ore
resources that the property contains.
HecIa Mine.
at the Hecla mine the management
and production of mineral throughout
the year. and finished sinking the main
Shaft from the 120O-foot level to the
1600-foot level, where great station
has been cut out and drifting com
menced on the course of the vein to-
wards the ore channel Fear was for
merly experienced that as develop
ment progressed in depth on this pro-
pertY that the nearby Tiger Poorman
mine. which has been abandoned and
now forms a water reservoir approx
mately 1900 feet deep and 1000 feet
long by the thickness of the untitled
ore spaces would cause the Hecla con-
siderable grief and expense in pumping
but this fear has been by no means
realized lis the Hecla has not shown
any abnormal increase in water flow
as development has progressed, and
to forestall any such emergency the
has provided one Of the
largest and most improved pumping
plants ever installed in the district.
This plant is situated at the 1000
foot level and the other main water |
sources in the mine are conveyed to it
by means of syphons.
This pumping equipment consists Of
duplicate G-inch by l2-nch Aldrich !
vertical quintuplex electric driven
pumps of the pot chamber design The
combined capacity of these pumps are
500 gallons per minute. but either
pump is capable OF handling the water
flow so far experienced in the mine at
any season OF the year. Each pump
IS geared through flexible coupling to
us horsepower 23O0-volt Westing-
house Induction motor of the Squirrel
rage type, The pumps are connected
o an S-inch column pipe through
heck valves and are equipped with
,-lnch bypass valves to relieve the
pressure in starting. A float switch
8 installed in the stump so as TO ring
IN alarm bell when the stump is full
" empty. In addition the pumps arc
automatically stopped when the suml
$ empty by the action Of the float
witch on no voltage release installed
n the starting boxes.
These pumps have been operated
Yearly three years and have given ex-
client satisfaction. They are COM
lact in construction, involving conf
>aratively little floor space, and re- :
emble two massive 5.stamp batteries
With the frame cut off at the cam
haft line, and will doubtless prove
imply able to take care of any water
