SHIPPING TO A SHELTER
The Copper World Extension
Ores to by Thorough
ly Tested.
MUCH DEPENDS ON RESULTS
If the Returns Are Satisfactory
Shipments Will be Contin-
ued indefinitely.

Parties are engaged delivering at
the Washington Commercial company's s
warehouse platform car load of ore
from the Copper World Extension mine
that is to be shipped to a smelter for a
test run. The ore is being hauled from
the mine by wagon, and if the returns
justly q continuation Of shipments they
will be kept up all summer. The ore
is being taken directly from the big
ledge, which will give the company
some idea of the general value of the
gigantic deposit. G. B. Harpham, who
has charge of getting out the shipment,
says that the first round Of holes blew
out over Is tons, and it left no impress
sion on the ledge. Then there is the
old dump, at the shaft where an
enormous quantity has been piled up
A wagon road just for this purpose was
recently completed from the mine to
the road passing through the old Gold
en- camp to Oroville. 1t is long haul,
but the entire route to the valley is a
down hill pull.
The Copper World Extension is one
Of the most extensively developed
group of claims on Palmer mountain,
and is located on the summit of that
prominent elevation only a few miles
from Loomis, The property was orig
inally owned by Henry Bahrs and Loitz
johnson, and a transfer was made and
a company organized some years ago,
Columbus, Ohio, parties becoming
largely interested. The property was
equipped with hoisting machinery and
q perpendicular shaft started near one
OF the out-crops. At the 200 and 300
foot levels cross-cuts were run to the
southwest. At the 200 foot level, at a
distance of 100 or more from the shaft,
a large ledge, or dyke, Of ore was en-
countered. A drift was run along side
Of this ledge for long distance, and
the ledge occasionally cross-cut. The
ore deposit is almost solid, and from 10
to 20 feet in width. Why this drift
was not run directly on the ledge. and
ore extracted as work progressed, was
never fully explained. The ore is
standing exposed, and will have to be
removed some day if the mine is ever
worked. The cross-cut at the 800 foot
level never encountered the ore ex-
posed on the level above, and the funds
became exhausted before deeper re-
search could be made.
No development work has been done
on the Copper World Extension for a
long time. The panic made it diff
cult to raise money for mining opera
tions, or for any other investment for
that matter. The showings are cer-
tainly such as to encourage further ex-
ploitation. Every old miner who has
worked on the property voices one and
the same opinion that it is the best
showing in quantity Of ore exposed
anywhere in this upper country. Ex-
perts who have examined the under
ground workings have made favorable
reports. The ore Is copper sulphlde,
and while it is not classed as high
grade it has given good assays, and the
quantity seems very great 1t is the
concensus of opinion that the only cer-
tain way Of demonstrating the true
value of the Copper World Extension
is to sink to the 500 foot level, or even
deeper, and then prospect by cross
cuts. This would require the expen-
diture of considerable money, yet the
chance of success Is such as to encour-
age an undertaking of the kind. Prob
ably If the returns from the shipments
now being name are satisfactory to the
officers of the company the shaft may
be continued down and the ground
thoroughly prospected.
