The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1918-06-06

In places the gouge is very strong
comparable with that we usually find
marking the important faults.
In the east 100 feet of the west
drift, the gouge is smaller and brok :
en- up into gray gouge seams dis.
tributed through zone wider than
the drift. This zone abounds in
quartz seams and large lenses, with
much pyrite. 1t is said that little
galena occurred in a section of quartz
about 20 feet long. Dips along the
vein vary from 60 degrees to SO de,
grees northward. About l20 feet
west of the shaft raise was put up
about 80 feet per Ruch. 1t follows
the gouge at first but soon the latter
bends toward the left and goes into
the foot OF the raise. The object of
the raise was to come up under the
ore on the 400-foot level.
! The strong, modern appearing
gouge of the six hundred fault, the
character of the quartz and the almost
exclusive pyrite naturalization sug-
gest that it is one of the system of
what we call post mineral faults,
meaning thereby faults younger than
the period of commercial ore formal
tion in the district. 1t belongs to the
same category as the Heating vein,
but may be slightly younger.
Il will now return to further dis
cussion of the ore bearing vein on
the 400-foot level. | am very fav-
orably impressed by it. 1t unquestion.
ably belongs to the system of ore
producing veins of the Wardner dis
trict. The vein that it most nearly
resembles is the Senator Stewart,
very highly productive in the Stewart
and Ontario mines. The ore in those
mines was cut off by faults, On the
northeast the vein terminated against
what I have recently described as the
Late Osburn fault. Before the Late
Osburn movement the vein was in
block of Upper Burke quartzite that
was north of the Osburn fault in its
early stages. | have long been con-
sidering the probability that the
block containing the Stewart and On
tario mines was cut from the block of
Upper Burke that lies between the
Haystack and Osburn faults as map
ped in my 1912 paper, and have
thought it probable that thorough eX-
ploration Of that block in the vicinity
OF Milo creek might lead to a discov-
cry of vein similar to the Senator
Stewart. You have made that dis
covery. | cannot express the opinion
that you have found a faulted seq
ment of the Senator Stewart vein,
as your vein strikes lit
tie north of west and dips northward
as against the southwark dip of the
other vein; and. further, the meager
information about assays that l can
get seems to indicate a different lead
sivelr ratio, though the evidence is not
Ny impression is that
you have found another member of
the same vein system, of the same
character and under similar environ
ment.
SIN short. | am sufficiently Impress
ed by your discovery to recommend
further development of it. 1t is true
that, aside from the one lens of ore
mined, the vein matter i'll sight con-
sists of several bands hardly CONNER
cial. The Senator Stewart vein in
places is weaker than the weakest
exposed section of your vein. Be-
sides, further work on the 4O0-foot
level as suggested earlier in this re-
port may remove much of this APP
weakness. The vein will have
an underground apex. This apex, in
the portion developed, lies near the
side line between the Golden Curry
and Lillian claims. The apex will go
down eastward under the Heating
fault and as ut WILL for a consider
able distance, lie in the Golden Curry
claim, l will call the vein the Golden
Curry vein. Westward on the 400
foot level the vein will be cut off by
the six hundred fault short of the
property line.
Il am aware that it has been prop
osed to suspend development of the
until after the close of the
war; on account of the present high
costs of supplies and scarcity of labor.
