Melted from the North Star vein to
the independence vein, distance Of
about $500 feet, which will tap the In
dependence several hundred feet deep
or than it's present bottom level and
give a direct outlet to the North Star
mill which will greatly facilitate the
development and operation of the In
dependence, for which the new mill
will be used and the North Star ore
bodies will probably remain idle
awaiting a better market for zinc or
newer methods of complex ore treat

Other Lead Deposits.
Quite number Of carload ship
ments were made of similar high
grade crude silver-lead orr during the
wear from the Golden Glow mine on
Boulder creek in this county. One Of
the notable new developments in
Blaine county was at the Paymaster
mine, 40 miles from the railroad at
HALEY.
In Custer county leasing operations
we're continued and a number of car
loads of clean lead-silver ore were
shipped from the Red Bird mine on
Souaw creek near Clayton and big
reserve of 10 per cent mill ore devel-
oped In the same vicinity the South
Butte mine has a gossen ore shoot
500 feet long with a maximum width
of 40 feet and a 5O00-ton dump of
screenings worth 10 per cent lead and
ounces silver left from former shall
low operations. This is a decidedly
promising development proposition in
silver lead ore.
Seafoam District.
Mr.. Bell tells of another interesting
new development in Custer county
still more remote from railway trans
portation made during the year in the
so-called Seafoam district situated on
the upper tributaries of the middle
fork of Salmon river, the principal
center being 1875 miles from the near
est railway point at ketchum on
Wood river in Blaine county with an
oUUU-IOOL mountain ulNiuo iii'>i ~'-'o'
but over which the government is now
constructing a maximum per cent
grade wagon road 20 the Sawtooth
park country.
The United Metals and Power COM
pany, Pittsburg corporation, rebuilt
an old road into the center of this dis
trict the past summer and from their
Montana vein shipped carload oil
crude ore carrying values of $S2.50 per
ton in silver-lead and gold, which was
hauled on motor trucks to Mackay for
shipment.
In Prichard Formation.
Near the eastern margin OF the
great Idaho granite batholith in Lem
hi county, Mr. Bell states that SUD-
stantial progress has been made on
three separate new copper ore deVel'
opment enterprises. On two or them
treatment plants are now being con-
structed of 100 tons day capacity
each. one of them wet concentration
and the other a volatilization plant de-
signed on the process worked out pS
the u. s. bureau Of mines. These arr
the Harmony Mines the Pope-Shenol
mine and the Greenhorn mine, all SIT
uated in a thick series OF slllceou'
pre-C ambrian sediments definitely re
lated to the Prichard formation OF th
Occur d'Alenes and extensively III
truded with igneous rocks. Thes
veins consist of nearly vertical wei
sheared and pronounced hssur
courses varying from few feet up
10 feet in thickness, well developed D
adit tunnels to face depths varyln
down to 500 feet. A number OF car
load shipments have been made dur
ing the development progress or eac
Of these properties ranging from ~

According to Mr.. Bell the gold mil
ing industry of Idaho is at low epb
point of production with only two IN
portant sources of output at the pre-
ent time. These embrace the elabo
