The Marshall Lake Mining District
In Idaho county. Idaho, Is noted for hav
ing the richest gold bearing veins in
the county II not in the whole state.
The rich native gold specimens which
attracted such attention to the Idaho
mineral exhibit at the ST. Louis fair.
came from this district, out of a 20
foot drift on the Treasure Hill claim.
The very richest free gold ore in
the states permanent mineral exhibit
at Boise came from this property. The
veins of the district generally dip about
so degrees, trending as a rule northeast
and southwest. The ore carries iron
sulnhides, galena, zinc and gold and Is
well adopted to the cyanide treatment.
About so per cent of the assay value
is saved On the plates.
The district Is about rs miles south
and some west from Grangeville from
which city 1t is reached by a wagon
road.
1t is located on the south side of
Salmon river on the Salmon river slope.
The nearest railroad point Is Mccall,
on Payetth Lake. about 40 miles south.
There is an abundance of timber and
water and many. good tunnel sites
throughout the district
OF the more prominent properties we
will mention:
The Kimberly group, owned by Dan
Leroy and Sam Gerber, has a, splendid
lead, the ore from the upper tunnel plat
ing $3.50 besides carries high values
in concentrates. On ore taken from
the same lead in the lower tunnel as
says from $4,000 to $4,000 are often
had
l,A Inl.V
c. Fox, has strong and well defined
ledge which has been traced through
ten claims, is feet wide, of which
two feet on the hanging wall average
/ $4,000 gold to the ton. Assays over
100000 were obtained from some of
this ore. The lower tunnel Is just get
ting into pay ore. Some OF the hand
soonest specimens of gold ore, full OF
native gold, is from this property.
On the Mount Marshal group the most
work in the district has been done. 1t
ts expected that the present crosscut
tunnel of 1900 feet after being extend
ed another 200 feet will reach the lead
at great depth. The vein on the sur
face is about feet wide on which a
shaft has been sunk 100 feet and then
drifted on lead in bottom of shaft for
] 100 feet all in ore which plated $1,000
gold besides considerable heavy concen-
trates. A splendid mill is on the prop
erty.
The Goodenough group has the repu-
tation of being one of the great gold
properties In the district. Consider
able work was done about ten years
ago, a mill erected and a good deal
of high grade ore milled, but somehow
the management was not up to a strict
ly mining business and very little has
been done Of late years The reputa-
tion OF the miDs. however is intact.
The Jewel and Multnomah groups,
owned by Leroy and Gerber, is now
bonded to C. A. Heberlein, mining
engineer and geologist of prominence,
who had charge OF a large mining prop
erty in Mexico until the late Mexican
trouble when work was suspended, and
who travelled far and wide in search
of a good gold property and finally de-
cided on this valuable group.
The Multnomah ledge has three feet
of high grade ore that will average 500
and CONCENTRATES go over $500 to the
ton.
The Jewel lead has also three feet
} of high grade ore that will plate $3.50
besides the concentrates.
Mr.. Heperlein has taken a lease on
the Goodenough mill and will expert
ment with the flotation process in ex-
tracing the values from the ore.
There are quite a number of prospects
with good surface showings that have
as yet not been developed to any ex-
tent
This district is a good and inviting
field for the prospector as many valu-
able properties that are now hidden
may be uncovered with diligent work.
This district will make it's mark in
the future as a foremost gold producer.
