Custer County d-SiIver Mines
Red Bird Mine,

ore has been made during the pas
year in the Red Bird mine at Clayton
This deposit has an individuality al
its own and more resembles some o
the features of the ore occurrence a
the Hunter mine at Mullan than an,
other property | now recall in thu
state II has been developed by ser
les of short crosscut tunnels. Tit
deepest one, 1900 feet long, cuts thu
main deposit at vertical depth o.
900 feet below the apex and connec'
tons have been made through witt
intermediate levels at about 100 fee
intervals.
The main shoot is steeply pitch
ing pipe shaped channel that varies
from fifty feet in length in the upper
levels to one hundred twenty five IL
length in the lower levels by twenty
to forty three in thickness The for
nation Is hard silicous limestone
above Cambrian quartZite and gener-
ally stands like the walls of a cave
sists of a cheesey brown iron oxide
and soft lead carbonate mineral with
occasional enrichments of anglesite
and course native wire silver This
channel will average about 20 ounces
silver and 20 per cent lead to ton
with high excess in desirable iron
oxide gangue.
This property was operated prior to
twelve years ago to considerable ex~
tent and produced one million dollars
worth of ore during that period of its
operation above the 400 -foot level. AT
that time the bullion that was produe-
ed in a small smelter nearby had Il
be hauled by wagons 10 miles to the
nearest railroad shipping point, which
excessive transportation cost necessi-
tated the extraction of only the bet
ter values, and 80 per cent lead was the
lowest grade mineral that could be
economically treated under the con-
ditions of that day, which resulted in
leaving in these old upper workings a
very considerable reserve of 10 to Is
per cent ore. In addition to this ma in
channel Of mineral there are several
others of smaller dimensions, some of
them assuming round barrel shape
pipes that were little longer than wide,
but very persistent to the 400foot
level These additional channels,
which afforded a considerable proper
tion Of the mines former product, have
not been looked for yet in the lower
levels below the 4O0-foot, and with the
definite tonnage now developed in the
main shoot, and these added resources
yet to be opened, 1t is conservative
estimate to give this property above
its 900-foot level very probable re-
source Of 20 per cent lead and 20
ounces of silver ore that will aggre-
gate 100000 tons in volume which,
under present day methods Of treat
ment. and the approach of railroad
transportation now available within
go miles of the property at Mackay,
and supplied with motor truck haulage
to the railroad, it Is believed that the
deposits can be operated by local
smelling at handsome margin of
profit.
The main mineral channel shows its
greatest strength in the bottom level,
where IRON sulphide has commenced to
manifest itself but is associated with
some of the richest lead-silver values
found in the entire development. and
1t seems pretty safe to anticipate
continuance of the present fertility of
the deposit from its present strons
bottom showing to very considerable
further depth. This mine. from limit
ed smelter run and crude ore shippinS
output. produced 100000 pounds of
lead and $4,000 ounces of silver dur
ing 1913.
Lemhi County Lead Silver Mines
Pittsburg- Idaho and Latest
Out Mines.
In Lemhi county an interesting and
permanent lead-silVer
district is being developed at Gilmore,
near the head of the Lemhi river.
This district was afforded the con-
Of railroad transportation
about three years ago by the compile
tion of a branch Of the Gilmore and
Pittsburg railroad. 1t was an old and
well-known district containing num-
Der of handsome lead silver prospects,
md had been dormant for twenty
i've years due to its isolation from
abroad shipping facilities. When
he railroad reached the camp 1t i'm
nediately jumped into prominence as
IN important and profitable lead-silver
district. It's output has been princi-
oally supplied from the Pittsburg- Ida
10 and Latest out mines, with several
small contributions from prospecting
centuries.
These two mines produce lead car
Donate ore rich in iron oxide carrying
lverage values of about 80 per cent
cad and IS ounces in silver, together
With approximately so cents in gold.
The production has been entirely In
rude shipping ore of this class, With
nut milling facilities of any kind or
