RED BLUFF, Montana, Sept. Sd. 1888.
EDITOR CHRONICLE:
In my last letter, August 2sth. speciaI
mention was made of "Silyer Shove,
Hill" and some of the mines located
thereon-their deyelopments-its prom.
ise and the class of ore produced, At.
tention was called to the fact that the
mines located in this District on the
north side of Hot Spring creek carried
ores, whose principal value was in silver,
while those on the south eide produced
ores In which gold predominated. Ref
erence was made to the change in the
| formation-eranitic gneiss prevailing on
the south. while true granite, prophyry
and some slate. representing the country
rock on the north. An attempt was
made to show why so many mines were
idle, while q brief description was given
of the new process, its machinery, etc, In
this letter shall endeavor to describe a
few of the many leads on the south side,
the character of their ores, the method
of treatment heretofore In use, and the
relation the Walker. Carter process bears
to their future development and pro-
ductiyeness.
The Grubstske mine owned by Pope,
Buyliss & Mckee, has undoubtedly pro.
duced over s %, 600. 90 as attested by reli.
able vouchers which can be examined at
any time. This leads strikes north, west
and south east dipping to the east at an
angle of over so degrees. The vein is
opened and proved BY three tunnels
connected by raises. This development
has produced over 10000 tons of ore of
gross value of S40.Ol gold per ton or
$500, 10000, only one-third or less of this
value being realized. A peculiar feature
of this mine is, that In conjunction with
the pay streak" there is a portion very
rich and easily separated from the other
ore. 1t Is owing principally to this fact,
that this niue has yielded the large sum
mentioned. Upon examination find
that the average value of the ore shipped
to the smelters was $2l0 90 gold per ton.
North of the Grubstake lies the Col
conda mine owned by Hickman and Olds,
This property has been systematically
developed by series of tunnels and
raises showing fine strong vein, carry
ing gold ore that will sample and ASSAY
from $25 90 to $40. 90 gold per ton on the
average. The main or lower working
tunnel is driven some 900 feet develop
ing ore all the way and showing re-
inarkable uniform creyice. The nav
streak will average over three and one
half feet and in places is over ten feet
wide. A. conservative estimate figures
over ten thousand tons Of ore ''in sjphtn
and as much more probahly Ia reserve.
This vein parallels the Gfubstake vein
and dips to the east al about the same
angle.
