Dry ORE Belt.
Lying between Wardner and Wal.
lace, on the steep mountain slopes o
Big Creek and adjacent tributaries
that enter the South Fork from the
south side, there Is system of vel
defined faults and Hssure veins Of ex-
cellent promise Of future possibilities
for deep mining.
In this section the Yankee Boy mine
has been developed to considerable ex.
tent and carries large vein with a
narrow paystreak Of high grade min.
eral rich in silver showing an asso.
citation Of galena and grey copper, that
has made intermittent carload ship
ments from this development over a
period Of years.
This property has recently been put
in the hands of some well-known prac-
teal miners Of the district in two leas-
ing units. both Of which have already
made carload shipments Of mineral
averaging 200 ounces OF silver per ton
There are quite extensive backs OF
stopping ground already developed on
this property, and the operation Of
these leases is likely to prove success
full, both to the owners and the lessons
On this same belt. on parallel line
of assuring little further north, near
the valley, a large amount Of develop
ment has been done and in some in
stances shipments made at different
times from several mines along this
interesting line of pronounced fissur-
ing, including the Chester. United
Lead, Nellie, Argentine, Mineral Point,
Silver Rock and the Occur d'Alene De-
velopment Company claims, each of
these properties embracing good sized
groups, and have flattering prospects
Of ultimately encountering profitable
ore bodies If developed to sufficient
depth.
The trouble, however, with this belt
is the fact that its assures are mostly
contained in the Wallace slate forma-
tions associated with limited belt Of
st. Regis quartzite. These format-
ions are underlaid, however, at no great
depth by the most favorably consid-
cred Burke quart2ite which Is well
exposed in the long cross-cut tunnel
Of the United Lead mines. This open.
ing has been driven back into the
from convenient elevation
above the valley level 3840 feet to the
vein, which has been drifted upon 400
feet, showing decidedly well marked
flssure in the shaly Wallace forma-
ton that Is from one to three feet
wide. carrying quartz. siderite, galena
and grey copper.
In places this mineral combination
shows from to IS inches Of nearly
clean ore Of good grade in lead and
silver. This drift is directly under
some shallow tunnel development on
the same vein, on the dip. but thous-
and feet deeper in the ground, showing
4 remarkable persistency of the assure
in this shaly formation to great depth |
and more brittle quartzite formations |
where an expansion of the ore values
ire likely to be encountered.
This long tunnel has been largely
lriven since the geological survey of
he district by the government and has
demonstrated thier conclusions as to |
he relative rock structure Of the |
mountain to have been very closely
igured out.
The United Lead cOmpany's group Is
cry extensive in area and carries an
ther parallel fissure vein few hum
red feet south that should be opened /
y extending the cross-cut In the hope
I finding It in a more favorable ore
caring condition. This tunnel makes
splendid entry for the extended ex-

frong system of assures through this I
venue, or through one of the other 4
