IMPORTANT MINING DEAL.

FOR the past two years Charles
Dempster and his two sons have been
operating the Copper World Extension
mine, on Palmer mountain, and have
lspent large sums in developing the
mine, getting out ore and building a
long tram from the mine to the county
road on Palmer lake. Last year they
!shipped large quantity of ore to the
smelter, but were at great expense in
trucking the ore down the mountain
to the railroad at Nighthawk. The ex-
cessive cost of this long haul almost
eliminated all profit from the ore
treated and it was on account of that
loss that the gentlemen working the
mine installed the tram. The Demp-
sters have made legitimate effort to
place the Copper World Extension in
,the producing class and have met with
IoDstacles that would have discouraged
the average man. The last hardship
they were up against was the closing
smelters at Grand Forks just as they
had the tram ready to operate and they
have made no ore shipments for some
months. They have an ore reserve of
isufficient tonnage in sight to ship
isteadily, and more in the ground to be
uncovered and extracted, so it is not
on account OF the shortage OF ore that
the mine is not shipping today. Now it
appears that the Dempsters are to
spread out by taking over new and
more ground. They have secured a
royalty lease on the Copper World, "A
property that Immediately joins the
Copper World Extension on the west.
This property has been owned by Jer-
ONE Drumheller, son of that Eastern
Washington pioneer, Dan M. Drumhel-
! ler, of Spokane, and John Wentworth,
formerly of Loomis, for many years.
Securing this property gives the
Dempsters very large mining holdings
on Palmer mountain, and holdings
that have every indication of perman-
ent mines. In an interview with a re-
porter of the Spokesman-Review Mr..
Drumheller makes the following state
ment regarding this deal:
An expenditure Of $25,0 900 to $4,000
in development and equipment within
a year on the property of the Copper
World Gold Mining and Smelling COM
pany six miles from Loomis, WASH,
is proposed by Charles Dempster of
New York according to Jerome L..
Drumheller, president, from whom a
lease for five years on royalty basis
has just been obtained.
"Mr. Dempster and associates have
invested about $4,000 on the Copper
World Extension. .,k.ieining. from
(which they shipped 1000 tons of ore
in 1913" said MIR. Drumheller at his
office in the Columbia building, yes
terday. Associated with him in the
| enterprise will be two sons who are
mining engineers and eastern men of
large capital.
The Copper World is composed of
three patented claims, lying on the
forth slope of Palmer mountain. 1t is
traversed by a mineral zone 100 feet
wide and 5000 feet long, within which
there is II feet Of solid sulphide ore.
The continuance of the ore body has
been proven by shaft 140 feet deep
and drifts therefrom. and by short
shafts and glory holes for $50 feet on
the surface and by lesser surface ex-
plorations for 1000 feet.
"To facilitate shipments from the
Copper World Extension, Mr.. Demp-
ster and his sons have installed a
Riblet aerial tramway between the
mine and the base of the mountain at
Palmer Lake two and One-quarter
miles apart at an expense of $4,000
and invested an important sum in the
development of the property, upon
which they have lease that lacks
eight years of expiration. 1t is propos-
ed to extend the tramway to the Cop
| per World shaft, few hundred feet.
"The ore of the Copper World has
cupric content of to 5 per cent in
carload lots, an excess of iron, which
makes 1t desirable for smelling, small
values in gold and silver and high
percentage of sulphur.
"Mr. Dempster will sink on the Cop
rer World and engage in development
with a view of making the mine re-
sponsive within the period of his lease
hold He will install compressor and
other machinery.
"In addition to the 1000 tons ship
ped. 10000 to 40 900 tons of ore hav-
| ing a content of 3 per cent or more
have been blocked out in the Exten-
sion. Both properties embrace the
same lead, but the operations will be
conducted separately. Mr.. Dempster
operated in Rossland, B. c., 25 years
ago."
