to the right and left from each sta
ton on the strike of the ore bodies,
which have been developed on the 300
and $50 levels for a distance of about
600 feet along the strike of the vein.
Inolines and upraises have been made
from time to time, connecting the
different levels from the surface of the
600-foot level, which gives the mine
perfect ventilation.
The general workings of the mine
largely follow the hanging wall, which
is pronounced by some to be car
donated slate or lime, and by Others
parphyry. The hanging wall has a
varying dip to the southeast and an
undulating roll to the north and south
on the strike of the vein.
CHARACTER OF THE ORE.
The general character of the ore is a
soft, silicious lime, showing frequent
streaks of cinnibar and occasional
small deposits of sulphur and red and
/ black arsenic the latter being mainly
found in the roof, being apparently
deposited there by fumes, or possibly,
vapors. The sulphur and arsenic are
very limited in extent, and are gen
orally found close to small vertical
fractures; but their presence is not
considered detrimental for the reason
that the ore in which these substances
enter is not mined.
No foot-wall has ever been found in
! the Sunshine mine, one winze having
been sunk from the 200-foot level to a
depth of sixty-three feet, all the way
in ore, and then abandoned on account
of lack of air. A cross-cut has been
run from the hanging wall on the 400
foot level at right angles with the dip
of f1,a
feet, and the face is still in ore
It would be impossible to estimate
the number of tons of ore in the Sun
shine mine until the footwall is found,
and to find this a Wine will soon be.
started from the 600-foot level and
sunk until this wall is reached or the
ore values cease.
The ore is mined and milled as an
entire mass, without sorting, and
without regard to any particular pay
chute or streak, as the per centage of
waste is small, consisting only of lime
boulders which are piled up in the
mine, or an occasional lime horse,
which is either run around or over.
There are practically no timbers used
in the mine. as so far no Stopping to
any extent has been done; yet there is,
strictly speaking. no limit to the out
put of this property, which is govern
ed solely by the number of men en-
ployed. At present the output could
easily be raised to from 300 to 500 tons
daily, and even then the amount of ore
blocked out in the mine would be con-
stantly increased
The ore is all pay dirt, ranging in
values from S. to 500 to the ton, the
actual average value being known
only to the management; but accord
ing to the writer's personal opinion and
observation, from actual assays made
by outsiders. from his personal inspec-
ton of the mine his knowledge of the
general management of the mill. and
of the quality of the product. unin-
tentionally observed by him while at
the cleanup OF the mill, when the data
for this article was gathered. leads
him to believe that the ore will aver
age right up with any ore to be found
in the district.
The Sunshine mill was planned and
built for a capacity of 800 tons daily.
excepting as to teaching tanks, which
can be added at pleasure at slight
expense. 1t is now treating about
sixty tons of ore per day, and the total
number of men employed at the mine
and mill does not exceed twenty.
The cost of mining and milling, in
Guiding all expenses of whatever ma
ture, is less than So per ton.
THE OVERLAND MINE.
A visit to Sunshine would not be
complete without an inspection of the
Overland mine, in which most i'm
portant strike has been made of late.
The Overland joins the Sunshine on
the north, and is f1anked by the Red
Cloud on the west. The Overland shaft
has been sunk on the southwest cor
ner of the group, only few feet dis
tant from the Sunshine and Red Cloud
properties
The shaft on the Overland, is now
down to a depth of 100 feet, twenty
feet of which is in ore, and the bot
tom showing we'll. The ore ranges in
. values from Sc to s24 in gold to the
ton, and increases in quality with
depth.
The Overland's hanging wall is a
black lime underlaid with a narrow
sheet of black porphyry. while the ore
is a silicious quartz, very similar in
appearance to the rock that carries the
values in the Sunshine mine.
D. C. Macintosh, who has charge oil
the work. being done in the Overland
is now timbering the shaft preparatory
to putting in hoist, which is expect
ed to arrive early this week.
Being curious TO know just how much
truth there was in the reported strike

pieces of ore at random from the Over
land dump, and when he returned Il
