Large Tunnel in Idaho-Gratifying
Results in Saving "a High Per-
centnge-CIaim Filed on City
property-Ore Is Better Than 1t
Look--MininE Notes.
Last week the Mammoth Mining com
panv. of Wallace, Idaho, broke ground
on the largest piece of development Work,
with one exception, Yet undertaken III
the Occur d'Alenes. This is no less than
the running Of tunnel from the level OF
CANYON creek to cut their lead near the !
west end of the ground. The tunnel will
be approximately $500 feet long, and will
/ 100 feet below the deepest work yet
done at the point of intersection, and
600 fet below the deepest spot yet worked
in the mine The time required for the
completion of the tunnel is largely con-
iettuial. as the character OF the work
frequently changes, but 1t Is approx
mately put at two years.
An undertaking of this kind, costing
$4,000 to 100000 before u dollar of it
can possibly be returned, Is abundant
proof OF the faith of the owners i'll the
permanency of the Occur d Alene ore
bodies, as if the chute did not go down
the whole cost would be "a dead loss But
in the history OF the camp there Is no
case which would cause any doubt TO
creep into their minds that there was as
much OF more ore at that depth than
there has been on any of the upper levels.
Before the tunnel is completed the
shafts of the Helena Frisco or Tiger
Poorman may have attained greater
depths, measuring from the surface, than
this tunnel will cut, but it will be 200
feet deeper than the Helena Frisco now Is
and 400 deeper than the Tiger Poorman
1t is confidently expected that both OF
those properties can be probably
worked to twice the depth they now are,
hosting the ore and pumping the water,
and if that be true, the Mammoth with
that immense depth before it is neces-
sarv to hoist pound of ore or pump a
gallon of water would seem even when
the lead is cut there to be only in its
infancy, and that it will be generations
before its lower levels will be worked
out.
saving a High Per Cent.
The electro-cyanide plant of the Re
public company is making gratifying
record in saving high percentage OF thu
gold. The actual saving for August wa
81 per cent. On 800 ore this would leave
so in the taiings, and these are belns
saved for future treatment.
The average saving of gold in one da.
this week was 90 per cent, one vat return
. ing 95 II per cent.
Mining men say these results are re
: markable, especially when the hfgh grad
of the ore is considered. The percent
age OF saving is as good in high grad
= as in low grade ore.
