The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1920-04-01

t pressed scientific opinion fated thi
r famous ore body to run out at TIT
= 2OO0-foot level. In one of my old re
=, ports l predicted that this ore chan.
5 mel would be apt to go as deep as an,
in the district by reason of the mani.
fest magmatic depth penetrating con.
tact dixie of basic igneous rock witt
, which it is associated. If the exten.
sion of this new 2OOO-foot drift prove,
the ore channel to be as prolific as il
was in the 1900 and the lead value.
already found are just as clean and
the silver values just as high. l should
consider the chances of this ore chan
ners persistency to further depth are
equal to its past performance regard
less of the formation change on which
its failure was predicted based on the
adjacent Tiger Poorman experience
The Tiger Poorman was either a cash
vein by comparison or, as previously
expressed years ago struck a tapering
choke bore in the channel of its as
cending ore solutions and will be well
worth reopening and testing out at
further depth

The big ore shoot of the Hercules
mine now being operated down to the
eighth level below the main No. 3
drainage adit at the close of the year
was producing 600 tons Of high grade
concentrating ore a day with half
crew, has a vast amount of very

district; the operation Of this enter
prise has been largely concerned with
hammering out ore extraction since its
inception as producer, without much
regard for new ore shoot develop
ment, and still continues very prom

mage along the course of its powerful
fissure and extensive claim area.
Tamarack & Custer.
The Tamarack & Custer mine at
Nine Mile creek is the young giant OF
new ore development in the district
Its management added marked laurels
to its resources by the penetration
through the long Puritan tunnel near
the level of Nine Mile creek, of the
west end of its 400 ore body which
was found to be in exactly the posi-
ton surveyed for and on which a drift
had already been extended at the end
of the year $50 feet in just as clean [
lead and silver ore conditions, thick /
ness and general quality as in the No /
4 tunnel development 400 feet verti- /
cally higher. This new discovery is /
nearly 1000 feet below the highest ore
crest of the mine at the Custer end of |
the shoot and at an elevation $500 !
feet above the point at which the /
nearby parallel ore body of the IA
nous Standard Mammoth mine taper
ed out with the prospect at this time /
that the ore channel is passing from .
an overthrust segment of Prichard .
formation atwhic it outcropped into /
the more popular quartzite wall rocks |

Callahan.
Across the canyon at the Interstate
Callahan mine the most notable oc-
currence of the year was the discovery
at the No. shaft level, that the pre-
vious development to the eat of the
like had been carried on a narrow
split off the main fissure and that
the main ore body was parallel to the
lrift for a long distance, disclosing an 4
additional big segment of the charac-
eristic high grade, clean zinc-lead ore
'or which the mine is noted that will !
enhance and increase its
productive capacity and known re-
sources while an extensive amount Of I
