plete a success in saving the values as
was anticipated, and several changes
and adjustments had to be made, which
however, are now believed to be COM
plete and in shape to make a much
better saving Of the mineral values,
and an increased yield from this prop
erty may be reasonably anticipated.
The Wilbert mine has continued under
steady development throughout the
year and has maintained its reputation
as an ore resource fully up to the an
ticipation of its promoters. In fact,
the ore body in the lower level has
shown much greater lineal extent
than originally anticipated, and gives
evidence of considerable magnitude
and Importance as this work pro-
crosses
Wood River District.
BY reason OF the active market for
zinc mineral, the base zinc bearing lead
silver ores of the Wood River district
have attracted considerable attention
from investors during the year. and 1t
will not be at all surprising if a sub
stantial revival of mining Is exper-
fenced in that old district during the
coming season, as its western por-
ton has been made much more access
sible by the extension Of the oregon
Short Line railroad to Camas Prairie,
which also makes accessible some very
interesting gold ore deposits for which
that portion of Blaine county is noted.
An important revival of silver lead
mining and smelling in Custer county
was made during the past year by the
acquisition of the old Clayton Mining
& Smelling companys property in
Clayton, which is now being operated
under the management of r. I. Tus
tin. This company is running 1907
ton smelter at Clayton and is maxi
ing an output of so to 100 bars of bull
lion per day, principally from ore de-
rived from the Red Bird mine on
Squaw creek, which has been extern
sively developed and is showing q large
reserve of desirable smelling ore. This
company has several other interesting
ore deposits that are now being fur
Their developed, and have a very fav
orable prospect of establishing a steady
Output of rich silver bearing lead-sil-
yer bullion.
The increased zinc yield of the state
has come principally from two mines
in the Occur d'Alenes. The Success
mine, which is owned by II. f. sam
uels, and is treated principally for its
zinc contents. This property laid idle
for a number of years and was consid-
cred worthless as a source Of mining
profit, but under the venturous ham
ding of Mr. Samuels, a process has
been worked out for the successful OPP
Grafton of the rather complicated ore

has proven under the favorable market
conditions quite profitable during the
past year.
The Occur d'Aienes.
The Morning mine is the second
largest producer of zinc in the Occur
d Alenes. At this point the zinc min
eraf is derived by q very complicated
mefallurgical process as a byproduct
from the treatment of the very refrac-
! tory lead silver ores which this prop
erty carries. The extremely refractory
nature of the ore Of this great mine
still involves very serious loss In
treatment, but the company is spar
! ing no expense to increase the saving
and is continually experimenting with
new processes to this end.
| There are a number OF other zinc
| bearing lead silver deposits in the norti
and south ends of the Occur dAlene
district that are profiting by the ex-
ample of these two pioneers in zinc
mineral separation and an increased
yield of this useful metal may be ex-
pected from Shoshone county unless
| the market for the ore Is destroyed by
adverse tariff legislation.
The copper output of Idaho during
i1912 showed an increased yield of loo
per cent over 1911 and will aggregate
considerable over 100000 pounds, and
was largely derived from two mines
the Snowstorm mine in the Goeui
dAlenes, which has been equipped
with a concentrating plant making
available its finely disseminated sui
phide ores. and the White Knob mine
owned by the Empire Copper com
pany. at Mackay, Custer county.
The White Knob mine employed
quite a number of men throughout the
year in small leasing units. and made
a splendid aggregate output of min
eral, of a total of something like 26,00l
tons, containing about per cent cop
per and SO or 81 in gold and silver pei
ton. BY reason of its fluxing value
III THIS lOW-STaue ore WAS afforded very
reasonable freight and treatment
charge 10 the salt Lake Valley Smelt-
ers and returned a fair margin of prof.
1t over operating costs to both leasers
and owners.
II While the results of its extraction
has materially strengthened, the pro-
bable merits of the property as fur
II Their source of ore is so much so that
the company has undertaken the fur
Their extensive development of the de-
post at much greater depth, and are
planning the expenditure of larger
amount of money to determine the ex-
tent and continuity or the different ore
bodies at much lower level. with emf
nent prospect of success and the es-
adjustment of steady copper pre-
Queer of considerable capacity.
