Ihe ores are OF two classes, Occrrr
ing III distinct ana widely separa reC
ve;ns-one sl,iceous ard free milling
ahd the other pyntic and ha>e--th,
latter being too low grade to pay the
high charges for transportation aut
treatment at smoIter necessary to Sc.
cure its minerals.
The property owned by the Lookout
Mining company consists of nine loGe
claims, approximating one hundred
and fifty acres. These claims cover
the west side of Lookout or Rose
mountain and have, within thei,
boundaries. differences of elevation OF
ABOUT one thousand feet.
This property has been developed by
means OF tunnels. the configuration of
the ground affording exceptional nd
vantages for this method of mining
The openings, exclusive Of the dis
coveries of the various claims, consist
OF four tunnels-l. >. 3 and 5--whose
location and vertical depth are shown
by Photographic s'sctches.
Tunnel No. / has been driven in on
a stringer of quartz a distance of one
hundred feet, the stringer increasing
in width as depth was attained until
1t Joined the main body, which, where
cut, shows It width of eight feet, aver
aging about $40 per ton. This is a
stratified vein at this point of silicenus
ore, lmpregnated with oxidized iron in
places. Its strike, or course, is north
west and southeast and dip about So
degrees to the east This strike and
dip is practically Identical with that
OF the talcose vein followed in Tunnels
Nos and . and Identifies this vein
with that found in Tunnel No. /. prov
ing its continuity for this 1listauce-
about 1900 feet
Tunnel No. 2 has not been run into
solid formation and shows nothing bu,
detached pieces of quartz.
Tunnel No. 3 was drivon through a
large body Of broken quartz near the
entrance to the talcose vein. which it
follows soutl,easterly. developing
quart the entire distance. Unfortun-
ately the strike Of the vein is SO near
ly parallc! with the general trend Of
the mountain that sufficient depth is
NOT gained to show the character Of the
vein in its place in solid formation.
The body OF ore near the entrance,
however, would Indicate Il large china
ney lying to the northwest Of where
the tunnel cats the vein, but as to run
on this course would speedily bring the
tunnel to the surface again, the di-
rectors wisely concluded to drive IL
tunnel further down the mountain
that would not only develop any Chin
neys that might occur in the talcOse
vein but also give an opportunity to
fully explore the numerous cross veins
which occur along it's line
/, Tunnel No 5 was started ard rul
for this purpose and is now in dis
tance Of about four hundred and City
feet. In the first 300 feet the same
was encountered as IN Tun-
nels Nos. and 3, i. e. the vein was
broken and flied with masses of coun-
try rock. the walls standing OCCASION
ally as detached pieces. In running
this tunnel about fifty tons of ore have
been extracted in the shape of broken
quartz, and two cross veins cnnouu-
tered, one ald two feet thick. assaylng
from ten to forty dollars per ton.
These veins have Il strike at right an
giles to the course Of the tunnel. dip
ping about thirty degrees TO the south
east. The country rock on the bang
ing wall is marked by numerous small
OF quartz, which would indi-
cate the existence of large bodies Of ore
in that direction extending parallel TO
the line Of the tunEel.
AS shown, this property can be de-
veloped to depth of one thousand feet
without machinery or the attendant
expenses of fuel, engineers, etc, by
means of tunnels. There is an abund-
lnce Of timber for mining purposes on
The ground which can be conveyed to
the working tunnel by means of the
gravity tram now in operation from
the entrance of Tunnel No. to the
wagon road at the base of the noun
tain. The south fork of Gold creek,
which heads in a small lake at the foot
If the mountain, Is capable of furnish
ing an abundance Of power for the op-
Grafton Of mill during the summer
and might, by covering lozes
and pipes to prevent freezing, be util
lied the entire year.
The ore is free milling. aud by eX-
tending the gravity tram to the mill,
,an be passed through the batteries
with only one handling, when it is
shoveled into the car from the face of
the drifts or run in from the chutes.
This fact will allow Of its being milled
FOR not to exceed So 80 per ton. leaving
4 handsome margin for mining and
profits on $40 ore, even IL the small
cross vein.
A wagon road connects the mine
with the town of Pioneer, distant ten
miles, which lies six miles north
westerly from Gold Creek station on
the Northern Pacific railroad, making
the haul for supplies sixteen miles.
In conclusion, l wish to state that
this report is not as favorable as the
showing of extracted ore on the dump
would appear to justify, aud attribute
it to the fact that in the broken ground
deposits have been hnrriedly timbered
TO avoid cave-ins that have not come
under my observation.
