CENTRAL IDAH0IS VERY ALLURING MINING REGION

T cherty limestone formations, traversed
by dozen big parallel dikes of rhyol-
tie and silieeous granite porphyry. These
dikes strike almost due north, are yer
teal, follow out into the limestone
series for several miles and carry some.
very promising manifestations OF lead
silver bearing brown iron ores. The
most noted OF these prospects is the
Kennedy lead mine, half mile north
Of the eopper-bearing granite lime con
tact. This property had q glory hole
discovery OF earthly brown iron ore on
the west contact OF q 40-foot porphry
dixie, presenting the top Of an ore shoot
20 TO 20 feet wide and 20 feet long,
which has since been stopped with square
sets down 10 the 2O0-foot level below
the surface quarry, and has produced
200 ears Of fluxing ore containing a big
excess in iron oxide, very low silica,
about 10 per cent lead, and ounces
silver, with an occasional ear of much
higher values, also affording q kidney
Of clean galena occasionally, carrying
two ounces of silver 10 each unit of
lead. This contact carries half 4 dozen
other smaller pipe-like shoots of oxidiz-
ed ore that usually occur at the inter
seetics OF zarteal cross assures With
the dixie. Recently a good shoot Of ore
vas found on the east contact Of this
big dixie From It ear load shipments
have been made containing 20 per cent
lead and 20 ounces OF silver per ton.
Horseshoe Mine
On another parallel dixie half a mile
further northwest, the Horsheshoe mine,
whose east contact with the blue lime
stone has been developed by tunnels
and an inside Wine shaft TO q depth IF
800 feet, has shipped $50 cars OF simi-
lar brown ore, containing a high excess
in iron and Is TO 80 per cent lead, with
three-fourths ounces OF silver TO each
unit OF lead, in lens-lke bodies with
maximum dimensions OF 20 feet wide
and 100 feet long and high. Recently
leasers extended the inside shaft Is
feet on the vein. which, due TO its slight
dip TO the east, had passed through the
porphyry into its west contact with q
broad band OF massive marbleized lime
stone and in this contact had penetrat
ed body of complex sulphide ore con-
sisting principally of pyrite. pyrrhitite. /
and ehaleopyrite, containing K ounces
silver, 50 gold, and 6 per cent copper. I
Antelope Lead Mines
Another interesting prospect for sill
ver-lead ores tributary 10 Mackay is
the Needle Cos. mines on Antelope
creek, % miles south, connected with a
ine road with a uniform light grade in
favor of the load. This property has
been developed to maximum depth
If 40 feet and a total length OF 500
feet underground, while its vein courses
Ire traceable at the surface for 1000
feet, with promising showings OF lead
bearing gossan.
The total production from this limit,
d development has exceeded $50 ears,
" 1900 tons of crude shipping ore.
consisting of earthly brown iron oxide

IN ounce Of silver to the unit of lead,
md 81 gold per ton; an occasional ear
DAD among these shipments has carried
IS high as three ounces of silver to the
init of lead and several dollars gold

Bayhorse Mining District
It is 60 mics from Maekay 10 Challis,
he county seat OF Custer county sita-
ted on the west side of the Salmon
liver. The two towns are connected
" one of the finest highways in Idaho
md though bordered by ten to eleven
thousand feet elevations on either hand
,long its course through the upper Lost !
liver, Antelope, and Round valleys, t
quite is over a remarkably low pass,
With maximum grade Of i've per cent.
From Challis an easy river grade ex-
ends up the Salmon canyon and Stan
ey basin to the Sawtooth park eoun-
nv, whose beautiful ehaiu of glacial
axes and rugged mountain settings are
unsurpassed for scenic beauty anywhere
n North America.
