The Annual Report Of the Biggest
Gold Mine on Earth.
The following abstract Of the official
report of the Alaska Treadwell Gold
Mining Company, covsring the year
ending May 81. 1898, h taken from the
Engineering and Mining Journal:
The report Of this company covers
the year ending Nay d, 1898. AS u.s.
ual, it goes into the detAilnof opera
tions very closely, and lives the most
nearly complete, stateuaent and analysis
Of mining and milling coeEs that can be
presented; statement far more elabo-
rate and precise than. Is published by
any other mining company In existence.
The ore mined during the year was
254, 329, tons Of which 227, 692 tons came
from the lle-foot level and 26, l37 tons
from the 220-foot level which has been
recently opened. Ia addition to the
ore mined, 1924 tons at waste rock were
taken out and trammed the dump. The
cost of mining, las shown below, was
59.49 cents per ton.
Development work on the 110-foot
level included 376 feet of drives and
crosscuts and II upraises for chutes; on
the 22O-foot level 1882 feet of drives and
crosscuts and IL uprpises. The new
main shaft was sunk 4sS feet, and sta
tions cut at the 22O, the $50 and the 40
levels
The report Of Superintendent Robert
Duncan, Jr., says: ''As littl develop
ment work WAS done In the loft. level,
there is little new to report. The ends
of No. l and No. 2 west drifts are now
in slate footwall, and are discontinued,
Nos. 3 and drifts west are in fair ore,
and will be driven IS required. The
ends of the drifts Nos. and west are
now in footwall; therefore it can be seen
that the footwall at these points on both
levels has big swell in it or it is turn
ed more to the north. Drifts Nos. 4
and S west on this level are still in good
ore and are still being driven. Drift
No. l cast has also been driven to the
footwall and discontinued. Nos, and
east drifts have also been discontinued
as the faces Of both are in poor ground,
which was expected; in fact, Nos. ], 2
and 3 east drifts on this level have de-
veloped entirely new ground, which
contains good ore. on the adit and no.
#. levels the ore extended east, little or
no distance beyond the main crosscut.
Nos. 4, and drifts east are still in
good ore, and are being driven.
"Sinking has been continued in new
main shaft throughout the year, and
very slow progress was made with it, as
the ground was extremely hard to drill
and blast, and we were much troubled
by water. The shaft is down 458 feet,
and cut the vein in May. We find the
vein at this point exactly where it
should be. A sunlp is now being cut
and chute put in at the 440-ft. level,
and it is expected to begin prosecuting
the vein soon. Sinking the shaft on the
vein will also then be continued. The
reserves of ore in sight are estimated as
follows: Adit and loft. levels, 2,O66, 600
tons; total ore reserves available for
mill, 4, All, 500 tons. The reserve ore is
measured from the ends OF the different
east and west drifts. No account is be-
ing taken OF the ore beyond the faces OF
the drifts; fair percentage is also de-
Quoted from our actual measurements
for waste material that may be in the
ore. In fact it would not be unreasona-
BILE to add 1900, 600 more tons of ore in
sight in the mine"
During the year the mill of $40 stamps
crushed 254, 1923 tons of ore, the cost
being 37.O8 cents per ton. The usual
repairs were made. The mill ran BAT
and Is hours.
The COLONIZATION works were kept
steadily at work, three furnaces on the
company's ore and two on ore from the
Alaska Mexican mine. The cost Of
chlorination was s7.s3 per ton treated.
