PRINCE CONSOLIDATED

AT a meeting OF the board of direct

Company. held in Salt Lake September

ounces in silver and $3.50 in gold per

The work of sinking the new verti-
cal shaft. which is down a distance of
400 feet, has already been started.
This shaft was commenced over a year
ago to afford better outlet for the
large tonnage of ore, that the company
was shipping. The old incline shaft is
down to the sixth level, where the per-
manent water level was encountered.
The new shaft was not extended to the
water level at the time. The first 100
carried on with the present equipment.
1t Is expected that the shaft will reach
the sixth level and prepare for the
pumping of water within thirty-five to
forty days. In the meantime all the
necessary equipment for sending the
shaft to the depth authorized can be
shipped and installed.
God be, the boilers and other equipment
for the sinking of the shaft and pump

secure this equipment.
The sinking of the shaft the addi-
tional 500 feet is expected to take four
months 1t is probable that Just as
soon as that work is finished the shaft
will be sent down 400 feet farther

The ore occurs first as a rich lead
silver ore about three feet wide In
what Is known as the Prince fissure
and, second, as a replacement of GER
tain of the limestone beds on either
side of this ,fssuras .A-complete, re-
placement of the limestone beds has
taken place for distance of 500 fee
in places and an approximate averagt
distance of 900 feet from the Princt
fissure over known distance of 1,50(
feet along the strike of the fissure.
Five different limestone beds above
the 600-foot level, varying in thickness
from five feet up to ninety feet, have
thus been completely replaced. In ad
dition to the five beds explored by thu
mine workings, two additional beds
one containing zinc, have been ex
plored by diamond drill holes. The or
occurs, as noted. in a limestone forma
ton known to have thickness .
1850 feet.
