THE SEMINOLE.
A Chat With Prof. Aughey Regard
ing the Mines.
The Developments and the Charac-
ter of the Ore.
The Possibility of Rich Gold Pro-
ducers in Wyoming.

Prof. Aughey, the territorial geolo-
eist, has returned from a visitto the Sem
mole mining regions, and was intero-
gated by a re~presentive of The LEADER
in regard to the mines. During the in
terview Prof Aughey gave the following
description of the SEMINOLE properties
The Seminole mountain is 80 miles
northo Of Rawlins- On this mountain are a
large number Of prospects. some of which
are sufficiently developed to be classed as
mines. Among the latter are the Star
and Hope, the Bennett and Meager, the
Jenney, the King, the Lost Treasure and
Emeletta- The two latter are best known
as the Tom Sun property.
On the Star and Hope. which l special
ly examined. two shafts have been sunk
en- on the vein to a depth of 65 and 10
feet. The vein pitches towards the west,
at first to an angle of Ice, then to 500 and
finally to 45'. In the first shaft, which
Mr.. Tenant has retimbered, the dip has
changed from l5' to So. The thickness
of this ore body ranges from two and a
halfto four and a half feet. The ore is
partially free milling, about half an ounce
Of gold per ton being obtained by ANAL
gamation. 1t contains also a large quaint
ity Of copper and iron pyrites carrying
gold. By running the t%ailings into a
Rouse concentrator, from Is to % tons can
be concentrated into ore, making
concentrates that would sell for from
$500 to 800 per ton, This would be the
most profitable method of working their
property, which is a very valuable one.
The King mine | did not examine, but
judging from the ore submitted to me it is
a very valuable one. Besides the free mill
ing gold which it contains it is rich in
pyrites carrying gold. For profitable
working concentrators must be employed
on this mine. which would much more
than double the gold production. Mr..
Tenant. who milled the ores from this
mine during the last season, obtained $l2
per ton by amalgamation alone.
The Lost Treasure and Emeletta mines
have been developed by a cross cut tunnel
and a drift of 100 feet on the vein. These
are body ranges from 81 to 7 feet in thick
ness. The ore is free milling quartz, and
nus far no barren spots have been en-
countered.
Two miles east of the above properties
Mr.. Ferguson, Of Ferris, is engaged in
sinking a shaft on a copper property. He
has reached a depth of l75 feet No con-
tinuous streak of mineral has been found,
but it contains pockets of ore of great
richness. | have Just assayed a sample of
ore from this mine which ran IS per cent
in copper, and G5 ounces Of silver per ton.
Most of the mines on Seminole noun
tain proper are gold bearing. The geo.
logical character of the mountain indicates
hat it must be ~eminently gold bearing.
Here occur metamorphic states that have
been crystalized by heat. Among them are
found hydromica, argellaceous and chlor-
lite states, whose crystalizationis less per
iect than mica schist and gneiss. The
veins Of quartz which contain gold and
Dyrites occur in assures through the states
and related rocks, which must have been
made when the metamorphic changes
we're taking alaee. In other words the
gold mines of Seminole mountain occur
in rocks of the same geological age. and
character as the most famous gold quartz
lodges of California.
The geological structure and character
of this mountain is the best possible for
extensive and rich gold mines, and
when once these mines are scientifically
worked with the proper expenditure Of
capital, they will turn out to be the most
abundant and profitable gold producers
on the continent. This may sound extrav-
agant to those geologically unacquainted
with this section. but tests already made
with crude appliances demonstrate the
truth of this statement. Such a gold re-
gion elsewhere would at c engage the
interest of capital to an extent sufficient
to secure a proper development of these
hidden treasures.
