bearing quartz in silcious wall rocks
This vein has been developed through
two adit tunnels with total length
of 1000 feet a face depth of 30 feet
disclosing a succession of rich ore
shoots sixty to go feet long with
stopping ground from six inches to ten
feet wide, with the interesting condi-
ton of finding some of the best values
in the widest swells.
The property Is equipped with p
ton mill and very substantial camp
building accommodations. lhe ore is
said to average $50 ton in free gold
with quite an additional value in rich
concentrates. The concentrates, con
sisting of blended mixtures of pyrite.
zine, lead and copper sulphide rhc
concentrates produced are said to run
several hundred dollars per ton in gold,
and the output for the year of this
small plant is said to have totaled fui
ly a quarter of a million dollars in
gold. The enterprise has been handled
in an intelligent, practical manner and
the owners are to be congratulated
on its selection and management
First on Paying Basis
This is the first of the numerous
rich gold-bearing fissures of the MAJ
shall Lake district that has been put
on a paying basis. The district has
them notably rich in coarse specimel
native gold and, judging from the ex-
perience of Mr.. Holt, the values seem
likely to be maintained in the more
favorable ore shoots to very considers
Ole depth. The district lies close to
he western margin of the Idaho gran
tie region in schist formations that is
'raversed by intrusive bikes of por-
)hyry and diabase with some zones OF
garnet rock. The veins are parallel
o the abrupt canyon slope of the main
salmon river and show a variation of |
lpex elevations of fully 1000 feet in
he district S cross-seetion, which should
# itself be an added evidence of deep
Gated permanency for the veins and
alues.
Boise county has been the banner
ounty of the State in gold production
or a number of years past, but the 1917
utput of gold from Idaho county runs
a very close race in gold production
his year, which is very largely ac
ounted for by the successful operations
f the Holt enterprise in the Marshall
AXE district.
The Warren Placer Section
Another important and promising
PURGE of gold was in process of active
evelopment during the year in the old
Tarrens Placer district, eighteen miles
of Marshall Lake. In this
istrict the Standard mine was develop
I through an incline shaft on the vein
80 feet deep, below the creek level, {
nd late in the fall some remarkably
eh bodies OF quartz were opened that
re said to give average assay values
places a foot thick of several thou
md dollars gold per ton. This opera
on is on a persistent fissure in gran
e formation that has been noted in
le past for lensey shoots of very rich
e, but the values now being found in
$ bottom development exceed those
und in any of the previous slopes or I
wells of the mine, and the owners arc 5
cling optimistic over their new dis c
very. b
An extensive group of claims adj
ming this property to the northwest '
being developed by the Unity Gold
ines company under the management
j. A. Chick, a former State Mine I
spector OIL Idaho. The central fea
re of this enterprise the Little I
ant mine which was operated over
irty years ago and produced some c
Oh grade silver-gold values. These
works are being cut at considerable
ditional depth through long cross
t tunnel, now in 1000 feet, and close n
approaching the vein. "
Tungsten Is Discovered. n
An interesting discovery in this tun-
] is the recent intersection Of blind
in in which some very handsom, u
scimens of sheelite a high grade ore
tungsten, was found and this vein \
to be drifted on to determine it, Il
,bable profitable resources in thin re
neral. This property also embraces g
old operation of early days known re
the Charity mine, which was noted 81
the production of punches of speci-
n gold ore. Choice specimens from u
S deposit sent to Washington over al
ty years ago were classified by Jana.
