The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1913-03-13

This ore BODY II from two To ~ feet
thick and carries some splendid show
ings of high grade shipping lead ore
containing from 20 to 30 ounces Of sill
yer per ton In lenxes up to three feet
thick. The average of the whole body
is estimated at per cent lead and 10
to Is per cent zinc. the latter fairly
free from iron and occurs IN clean
lenxes that will afford some crude
shipping zinc mineral from 50 to 60
per cent grade. The contiguous Gala
han ore shoot has proven length Of
147 feet. with It's full extent vet unde-
termined. but definite evidence In the
lower drift that It will be ESQ feet long
and carry an average value OF about
Is per cent lead and better than one
half ounce silver to the unit of lead.
The Callahan ore body has been
opened through independent surface
workings at a depth Of 400 feet, and
ut one point shows nine aud one half
i feet Of clean, loose texture. fairly
coarse grained galena carrying over
\ 20 per cent lead and 46 ounces silver
and presenting as desirable a charac-
: ter Of lead sulphide mineral as has
ever been found in the whole Occur
d'Alene district, which, together with
its relatively high silver values. Is a
gratifying tribute to ore bearing pos
sibilities Of the discredited formations
OF this section and proves they can
produce as clean lead and as good sill
yer as the more favorably considered
wall rocks where the assuring condi-
lions are right.
! There has been shipped from the
present development Of the Callahan
property AZ cars of hand picked min
eral that has averaged 70 per cent lead
and 40 ounces silver, which Is fully
as high silver ratio to lead II not
higher than the average OF the whole
Occur d'Alene district. In this con-
nection, and in support Of technical
exhaustion theories. 1t Is pointed out
that some Of the older and hard work.
ed ore bodies Of the Occur d'Alenes
are showing gradual loss Of silver
values as depth Is obtained, but an
interesting contrast to this condition
is the fact that two Of the deepest de-
veloped ore bodies Of the Occur
d'Alenes, now worked at a depth Of
fully 340O feet, still carry the maxi
mum silver ratio Of their best sui
phide horizons.
! Local authorities consider the wall
rocks Of Interstate ore body to be the
lower Burke, but the government map
puts it well within the Prichard areas

tie porphyry six to eight feet thick
which bears an interesting similarity
and probable relationship to the ore
occurrence as that experienced in the
Bonanza ore channel Of the Hercules
mine farther east.

crosscut tunnel. This mill is now
nearing completion and Is expected t.
be in successful operation by early
spring. while the area embraced with
in the company's territory and the
strike of other known ore courses
through 1t is such as to permit of {"
very extensive campaign of additional
development and the definite prospect
of finding other large ore resources.
The mine plant consists of number
Of new buildings, sawmill, large cleo
trio driven air compressor and the
main tunnel Is soon to be equipped
with electric haulage.
The mill Is half mile below the
mine and will be connected with ar
overhead tramway with a capacity Of
40 tons an hour and should existing
metal prices continue to prevail there

Another interesting ore deposit In
this formation Is that Of the Idora
Hill Mining company. over the sum-
anti from Nine Mile on Beaver creek
slope.
This enterprise. under an energetic
new management, has recently devel-
oped defined ore shoot to maximum
depth Of 500 feet through adit tunnels
and crosscut work. disclosing some
bodies Of fine concentrating mineral
four to six feet thick with occasional
rich streaks Of high grade shipping
ore. The full length of the main ore
shoot has not been determined but
gives evidence of continuing for sew
eral hundred feet, as indicated by
drifts and crosscuts along its course.

cent lead in the more definite reserves
