PRINCE MINE SCENE OF
DEVELOPMENT ACTIVITY

Over the mountain from Pioche the
Prince Consolidated mine u now the
scsns Of great activity. although
Il will probably be ninety days before
the No. vertical shaft now being
sunk reaches its FIRST objsctive-th.
eleven foot oxidizsd iron bed discov-
cred by the diamond drills In 1918.
This bed. which IL composed Of soft
iron OXIDES. assaysd $3.50 in gold and
IS ounces In silver. carrying practically
NO lead. being much richer than the
beds mined above. Although the
thickness Of the ore was definitely
determined and checked by several
diamond drill holes. the softness of the
ore composing this bed made the OBJ
tanning OF . satisfactory core dl:ncult.
a. the circulating waters used In the
diamond drilling under pressure
washed out much of the soft and prob
ably richer portions of the core. The
assays Of the cores consequently would
bs conservative.
Four hundred feet below this orebed
lies the sine bed. which was demon
strated to be on the contact OF the
shais and UNDERTAKING Quartzite. The
ceres .rom this bed were so;;d api

various drill holes was dedaite. the

tionally good quality and FREQ from
impurities.
Besides these beds It must be noteo
that the assure veins which run
through the minsralized section of the
Prince and from which In 1912 a con-
siderable tonnage Of high-grade lead
silver ore was extracted above thu
water level. 60 down strong below
water and give every indication Of per-
mansncs and productiveness. The first
class ore produced at that time from
various shoots in these assures as
sayed S4.20 in gold. 1877 ounces In
silver and 39.4 per cent lead: the SEQ .
ond-class assayed $3.50 In gold. 4s.s
ounces in silver and 3s5 per cent lead.
The Prince mine Is typical. example
Of replacement orebodies. the resul,
Of ascendinf minsralixing solutions
through the assures. and large and en-
tensive bsdded ore deposits were
formed wherever these solutions came
in contact with formations favorable
for the precipitation of their contained
values. Since the enrichment Of the
Prince lower beds was from the same
source as those above water level. II
IL possible that they will be proven tc
be fully as extensive, and In this con.
nection 1t should be borne In mind tina,
the upper beds have produced to dat.
over 100000 tons Of profitable ore.
The conclusion seems to be JUSTIFIED
that the orsbodies to be developed De

times greater than anything hereto
