Prince Consolidated
Opening StOpt On 400
Will Materially Reduce Mining Costs
Which Are Already Low-Dia-
mond Drills In Quartzite.

That the Prince Consolidated conn
oany is planning for a material in
crease in its output In the near ~,
IRA is evidenced by the plan Of de-
selopment outlined to the Record
during the week by General anaMger
A. Y. Smith.
Recent developments on the fourth
level have cut the bottom Of thA
srdat manganese bed on its dip and
is now proposed to run a tcross-cuc
% the east go feet and to the west
20 feet. when five new raises will
oe started for the purpose Of opening
new stope on that level. The rafS-
IS will be 80 feet in width. between
,ach will be left a 3O-foot pillar.
when the raises are carried through
TO the over hanging shale. the next
move will be that of tearing down
the pillars OF ore left by means q
a system OF cross-cuts and. begtpniu8
at the top and blasting thep "a
80 tLnt the ore may fall off into tho
vacant places left between the pii-
-ars. In working down these pillars,
ne men employed in the cross-cuts
will be protected by 35 feet Of solid
round. This system of mining IL
in vogue at the present time at the
Miami, Ray Consolidated and other
great copper properties.
Low Mining cests
The opening of the new. stope ON
lne 400 will materially reduce the
-ost of mining at the Prince Consoli-
.ated, which already compares fav-
Jrably with the costs of mining at
the copper mines mentioned. Mr..
J. Smith states that the present min
ing costs at the Prince are az low
as $1.10 per ton. ore delivered al
t Phoebe, which includes 30 cents per
4 ION for development and centa psI
% ton additional In loading box cars
v (which the company is Obliged to do
? .lmost veery day, owing to the ina
L 9ility TO obtain the desired number oi
;ondolas, or open cars.
