PRINCE CONSOLIDATED
SHAFT PASSES $50 MARK

SATISFACTORY progress Is peink made
In the sinking Of the new vertical shaft
at the Prince Consolidated mine and
the work Is being watched with intense
interest locally.
The shaft has now reached a total
vertical depth from the surface Of 55s
feet. and despite the heavy fow OF
water encountered an average advance
Of three feet is being made every day.
The formation is still In altered lime
shale, which Is at times slightly stained
with iron and traces Of manganese.
The how of water Is variable and
during the last ten days of maximum
now of over 200 gallons per minute
was handled efficiently and economical
ly by the new pumping installation.
The normal flow is about 125 gallons
per minute. which. however. Is expect
, cd to increase as greater depth an.
the mineralized area Is reached.
Three shifts of miners and pumpmen
are at present employed under the
management of Walter Fitch Jr.. and
the work Is being expedited In every
way.
At this date It will require an addi-
tional 276 feet of work to break into
the first orebed. which has been de-
scribed a. the silver orebed. on ac-
count Of its high silver content as
demonstrated by the diamond drill
holes put down by the company two
years ago.
This bed. which Is composed of soft
iron oxides. assayed $3.50 in gold and
rs ounces in silver. being much richer.
Though more siliceous. than the beds
mined above. Although the thickness
Of the ore was definitely determined
and checked by the several diamond
drill holes. the softness of the ore COM
, posing the bed made the obtaining Of
, a satisfactory core difficult. as the cir
culating waters used In the diamond
, drilling operations under pressure
:. washed out much of the soft and pos
A sibly richer portions of the core, conse-
quently the assays of the cores should
= be conservative.
At a still greater depth. approx
mately 2s7 feet vertical below the sill
yer bed. the base bed will be encoun'
tered. This orebed was demonstrated
to be on the contact Of the shale ant

satisfactory results.

this ore comes from what Is known

is being mined from the territory 6
jacent to the second level at verti
