Phoebe camp gets into fl tnm Is the
Mcndha, which has been making quiet
but steady shipments of ore TO the 10
cal smeltcrs for some time past. "a
report has been prepared for the com
panv, which, owing TO the extensive 10,
cal interests in this organization, VIII
he welcomed in Utah, rs well as IN Ne
vada.
The property consists of ten claims
located ten miles northwest or the
town OF Phoebe, as shown by the re-
port. The company also owns Two
Very valuable springs of water about
one mile distant from the group, the
springs being the only ones within zen
miles. except those owned by the
Phoebe Water company, which supplies
water to the town. The proposed ex-
tension of the Salt Lake Route tracks
will bring the property to within two
miles of the railroad. instead OF ten,
as is now the case The Mendha WAS
one of the first lead properties TO be
pro6tably worked without cheap trans.

Melissa and Hamburg claims Ihe
property is splendidly equipped for deep
work. Two tunnels have been driven
into the Melissa ground on issure VEN

Developments on the Hamburg consist
of a 300-foot tunnel, driven on the Nein

l25-foot shaft which was sunk IN orc
The report then says;
The formation in this territory pre-
sents the general condition of fiat
bedded eambrian limestone with lntru-
sive dykes of quartz porphyrN. The
veins are zones of silicious replacement
occurring along assures and beds in the
limestone formation-all Of which is
silicificd 10 a greater or less extent. IN
view of all the conditions, both the iis-
sures and bedded veins must be re-
earded as belonging 10 the same VEN
system. They evidently are contempor-
aneous in origin and the ores IN them
have been deposited by the same agen'
cies. 1t is evident that the quartz
porphyry intrusions above referred 10
have been the governing condition, both
as 70 the formation Of the veins them
selves and the orc contained IN them.
in the Hamburg claim the only VEIN so
far developed is "A simple iissure proba-
blv identical with the fssure vein No.

tion OF them that has been taken out

practically intact.
This ore is highly oxidiZcd in places
and shows much evidence OF teaching
action. On account Of this condition it
is very probable that high grade bodies
Of orc due TO secondary enrichment will
be encountered as development work is
carried toward the porpbyry- lime con

point TO this as the channel through

sures or bedded veins that may be found

During the early period Of the opera

ING mined from fssure No. !, only the
high grade material coaId be handled,
on account of prohibitive transportation
charges. For that reason much of the
lower grade ore in this vein was either
left in the mine or is now on the dump.
a conservative estimate for the quau-
titv and value of this material is that
there is at least 300 tons available,
having ap average value of $50 per ton.
