All Without Sorting.

Word has reached the local Offices of
the Weimer Copper company that the
mine management has Just forwarded
an additional ear Of high.grade copper
ore 10 the local market This will make
the third car that this remarkable
organization has made within recent
date, and while its values must re-
main an unknown quantity until re"
ceived at the samplers. il is thought
that the values will equal, if not eX-
ceed those of the previous shipments,
the latter ranging around II and is per
cent red metal. This company owns a
large acreage of mineral ground about
6ftyfve miles from the shipping point
of Dubois, Ida, and the more recent
history of the mine, or since the owner
ship has vested in prominent Salt Lake
hands, dlscloses an exceedingly inter
esting account of gigantic mining on
small scale.
The present company has had little
opportunity to accomplish other than
development work. which. necessarily
is small in proportion 10 the extent of
ground to be covered. In a recent re-
port of prominent expert the pres
ent SYSTEM of mining and the general
geography and geology of the group are
given, which will prove of interest 10
the stockholders of this red metal pro.
ducer. In part this report is as fol
lows.
The ore is covered with wash OF grav-
el and earth FRO mtwo 10 six feet deep.
and In order TO mine the ore pows and
scraPers are used to remove the wash,
which IS dumped down the hillside, thus
exposing the orc body. which Is then
broken down by means of one and a
half inch steel drill sixteen feet long at
tached TO a sixty-foot spring pole, a hole
is drilled through the ore and rock four
teen To twenty feet deep charged with
four TO seven kegs OF black powder which
when fired loosen $50 10 300 tons OF ma
terial. The rock is dumped over the
dump, the lower grade ore is stacked UP
between the tracks and left for future
disposal. while the shipping ore is loaded
into mine cars and run TO the ore bins,
from which the wagons are loaded for
transportation to the railroad.
The ore is hauled to Dubois station:
Ida, a distance Of fifty miles by wagon
over a good road. Each teamster has q
string Of three and four wagons hauled
by twelve 10 sixteen and twenty horses.
