Last week the Mammoth Mining com
pany. of Wallace, Idaho, broke ground
on the largest piece of development work,
with one exception, yet undertaken Ill
the Occur d'Alenes This is no less than
the running of Il tunnel from the level Oh
Canyon creek to cut their lead near the
west end of the ground. The tunnel VIII
be approximately $500 feet long, and will
cut The lead 800 feet below the surface,
100 feet below the deepest work yet
done at the point of intersection, and
500 let below the deepest spot yet worked
i'm the mine The time required for the
completion of the tunnel is largely con-
iectmral, as the character of the work
frequently changes, but it is approx
mately put at two years
An undertaking OF this kind, costing
$4,000 to 100000 before dollar OF 1T
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 or 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 proiitably
worked to twice the depth they now are,
hoisting the ore and pumping the water,
and if that be true, the Mammoth with
that immense depth before it is neces-
sary to hoist a pound of ore or pump
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 n High Per Cent.
The electro-cyanide plant of the Re
public company is making gratifying
record in saving high percentage OF the
gold. The actual saving for August was
81 per cent. On 500 ore this would leave
50 in The tailings, and these are being
saved for future treatment.
The average saving of gold in one day
this week was % per cent, one vat return
ing 95 IL per cent.
Mining men say these results are re-
markable, especially when the high grade
of the ore is considered. The percent
age Of saving is as good in high grade
as in low grade ore.
The camp is gratifed at this complete
vindicAtion OF the judgment of Patrick
Clark Old time mining men say the
achievements of MIR. Clark, in taking a
wild prospect 50 miles from a railroad,
locating the ore body, blocking out inn
mense reserves Of high grade ore, erect
ing a large and expensive mill, choosing
the right treatment for the ore, putting
up the necessary buildings, developing the
water power of the property, paying for
the big outlay, and declaring dividend
all inside Of Is months-are unprece-
dented in the history Of American min
ing.
Mr. Qark's friends are particularly
elated because his Judgment in selecting
the method of treating Republic ores was
slatly turned down by a number OF
experts who inspected the camp and
analysed the ores.
Camp Mckinney Claims.
Camp Mckinney, b. c., has the center
OF the stage in mining matters in Spo-
kane just now. The recent rich strike on
the Waterloo has done more, apparently
10 attract the attention of mining men
TO the camp and bring the investors for
ward with their cash than the steady
payment OF dividends by the Cariboo
company ever did. Free gold, visible to
the naked eye, always has an irresistible
attraction.
The second payment on the stock Of
the CaribOO company held under option
by the new company recently organized
was made last week, although it was not
due for about month. The formal
meeting to ratify the sale of the prop
erty to the new company will be held
an Camp Mckinney today. Although
Cariboo capitalization has been increas
ed TO 81 $50, 600, the stock is selling in
Toroato markets for about 80 cents
which is higher than ever and serves t.
demonstrate the fondness of the eastern
Canadian for dividend payer, which ha:
always been managed in a conservativ,
manner
The Waterloo company is completing
its incorporation. The promoters stock
which is half of the capital stock o
