plans temporarily. About so feet back
from the face nice stringers of galena
ore were cut. They were distinct clear
across the tunnel and in the floor one
was about 3 inches In width. 1t is the
intention soon to drift on these and
determine something of their extent
and value. No assays were made, but
in appearance the ore was of excell-
ent character.
Good Result From Drifting.
At 1850 feet in the tunnel stringer
Of spathic iron. having the appearance
Of ledge, was cut This was drifted
on to the east for about 20 feet and
widened out to 20 inches. The filing
was spathic iron, carrying silver, cop
per, gray copper and pyrites. An as
say of selected sample of this gave
$6S. chiefly silver, some copper value
and 50 in gold This iron is valuable
for flux and would figure materially
in reducing cost Of smelter treatment
1t is the intention of course, to do fur
ther development here. The values
and generally improved appearance
with the little work amply warrant it.
Argentine Ledge Is Strong.
At distance of 1886 feet from the
portal of the tunnel the Argentine
ledge was cut, about at right angles.
No drifting has been done on this.
but of course the company has in view
its development. 1t is a strong and
well defined ledge. about s feet in
width. The depth here is about 1900
feet. The company has ample ground
to explore this ledge both east and
west. The ledge filling is largely the
spathic iron characteristic of the dry
ore belt and it's values would most
likely occur in gray copper More or
less development has been done on the
Argentine ledge on adjoining ground

able ore has been shipped from upper
workings. It's values were chiefly in
silver and its iron was desirable
flux for smelling.
Mineral Belt Has High Grade Ore.
The highest grade ore mined In the
Coeur d'Alenes has come from the
mineral belt lying south Of the river
and more or less prospected from west
of Big creek to considerable dis
tance east Of Lake g,ilch. A series of
lodges are known to exist in the belt
though they are nowhere sufficiently
developed to be thoroughly under
stood Some of these carry lead ore,
while in other places gray copper will
be found. carrying high value in sill
yer, some copper value but little If
any lead. This latter is the general |
character of the ore which has been !
quite largely shipped from properties
further west In the same mineral belt |
as the Vulcan.
Valuable FIux.
Another feature of Importance IN
this product is the character of the
iron constituting much of the ledge
filing and its value as fluxing ma
terial. This latter will no doubt fig
ure strongly in the profitable working
of the ore. The possibilities Of this
mineral belt can hardly be estimated
at this time. with it's limited develop
ment. Well informed mining men be-
lieve 1t has a great future. Possibly
the best results will not be realized
till 1t Is opened below the water level
So far nothing has been done toward
sinking 1t must be borne in mind
that great depth has been the making
Of the biggest mines in the Occur
d'Alenes.
Notes OF tho Work.
The formation at the Vulcan is the
Revette quartzite. 1he lodges crossed
by the tunnel take the usual course of
all others in the Occur d'Alenes--a
little north Of west and south of east
The working equipment at the Vul
can Is ample. Power for the COM
pressor and other minor uses Is de-
veloped on the ground from head of
water taken from Argentine gulch.
Two shifts are at work on the tun-
mel. Right at the mouth Of the tun- {
mel Is a grassy plat Of ground. making i
an ideal spot for permanent camp ,
