There ia much ore left IN the pit and in the
mine which has been untouched
The ore was transported 20 the mill from
the mine b. an aerial tramwny shout ssooo
fees long.
Going UP the southwest fork Of the New
Year creek, for about q half mile and south
OF the New Year min. one reaches the Prince
Mine group which Is the property Of Western
Mines corporation. This mine Is on tha
south side OF New Year mountain and the
same ore body as the New Year mine. This
property Is almost a virgin mine. only ore
has been developed and some ore tested, Is
to values and process to treat the ore. and
also as 70 TONNAGE and possible available tom
mage for immediate milling and future de-
velopment The equipment for these mines and
mill viii be furnished through Fred n. vilss
q Co. OF Great Falls.
The mine tonnage has been proved By va
rious large open psts. tunnels and a glory
hole has been started The ore has been
sampled all over with excellent results. The
openings on the ore disclose = body OF ore
depth Of $50 feet along the dip Of the ore,
has been proven. The assays on the ore
from various parts Of the mine give as follows.
Lov-grade ore average $3.50 to $500 per
ton; this is the ore only considered in basic
calculation OF the millheads. assay around
$780, $40, $3.50, $3.50 and sz.2o. Some IN
over a width Of 160 feet. indicating a large
ore deposit to be developed Higher grade Of
ore gives values Of $500, s12.00. S1460, and as
high as $1,000 on q width Of feet TO 30
feet Of ore. Some ore screened for test gives
S245O per ton. Some assays have given values
at many places In the various openings Of
5000 and $4i.0o per ton. This indicates that
there will be very good millhead.
This ore like the New Year mine. is an
oxidized mineral composed Of iron oxide,
oxidized limestone, and iron carbonate in the
much altered limestone. The ore is soft and
easy to mine. The ore viii be quarried out and

the ore from the Prince Mine group as well
will comprise a modern crushing plant. tube

the cyanide section. The Merrill process viii be
employed for the precipitation Of the gold

the Prince mine. Later additional units viii be
added to the mill to bring the capacity up
to 500 tons daily. The company has its own
coal mine on the property, like the New Year
and many other mines in the district.
Leaving the western part Of the district and
going further south and around the New
Year and Pyramid Peaks, we reach Ruby
creek on the northwest side of Pyramid peak.
We reach the old Boulder mine which was
located in early eighties by w. Wilson, and
was developed BY several tunnels caved now.
They we're driven into the Silurian black
limestone along the contact with the por-
phyry. The formation was cut through ct
various places as part Of one tunnel indi-
Gated. the ore was high In silver and some
gold; the values we're around 100 ounces in
silver and about sI4.OO in gold. No record of
ro1tsr fo flohf nF he
ore mined is understood
Going back south to Boyd creek, and go
ing east TO Gilt Edge creek, we reach the old
mining town Of Gilt Edge, following the
creek up stream for about half a mile we
reach the CHIT Edge min In which was milled
the ores from the mines on the creek above
This mill was erected in 1888 It was then
a stamp mill and vanner OF rather crude
affair but produced much gold bullion from
amalgam from high grade ore milled. Then
In 1888 It was rebuilt BY Prof. W. B. Potter,
as a cyanide plant Of those days style, and
miIled a large body OF low-grade ute salts
factory for those min practices. It first
consisted OF a crusher, chfllian mill as puiyer-
zer and the stamps we're also used Next,
after the crusher, plates. and then when the
cyanide addition was made the plates were
removed. In 1895 the mill was remolded to
improve the cyanide practice but stiil all the

ore turned more basic with black sulphide

considerable amount Of gold. The unoffi-

nine including the silver, is around s12,00000.
Ore only OF q fair value was mined as the

The mines are located up the creek from
he mill about three-quarters OF a mile They
we're located in 1884-s5 by Wilson, Anderson,
