ton may not be amiss, especially to your

GOLD RUN DISTRICT
Is on the eastern slope of the Third East
Range, commencing at Rock Creek ranch
near Golconda and running southerly
with the range about fifteen miles, or,
more mprehensively, in townships 80
and "a north, range 40 east, Mount Diablo
meridian. The formation to the south
end is granite, gneiss and syenite, with
their notifications; further north the
states commence, with a performance OF
talcose schists, which iuclose most of the
mineral veins in that locality. Magnetism
states and schists predominant near the
north end, especially around the Golconda
mine and the Bonnifeid placer mines.
But little of the primitive rocks can be
seen, as they are submerged in tertiary
volcanic porphyries and the erosion that
followed that period up to the present
time The mineral veins are numerous,
more so than in any other district in the
State. Most of them are of tertiary
origin, radiatiag from the center of action
and parallel with the range. The largest
seem to be of older date, probably of the
cretacous period. The latter have been
reopened and filled with different min
erals and metallic ores, evidence OF which
may be seen in the Silver Bill mine.
which is being developed. This vein is
from % to 30 feet between walls; the
stratum of quartz near the hanging wall
is impregnated with grey sulphurets of
silver and gold, while the strata nearest
the foot wall carries argsntiferous galena.
Extensive operations are now in progress
on what was formerly known as the
MONTGOMERY COPPER NINE,
but which is virtually gold and silver
mine with copper base. The gentlemen
who are developing that property are
Messrs. Roulstone IL Bates. Mr.. Roul-
stone is considered one of the best and
most successful mining engineers on this
| Coast, while the latter is practical
assayer Of notoriety: These gentlemen
have quietly obtained about 6,OOO feet on
the north end Of their plant. But little
can be learned about their business, as
like most successful business men, they
are not communicative, but they have
their shaft down about forty feet. They
have drifted about Ia feet east towards
the hanging wall, but have not reached
it yet They are extracting some very
rich ore, some of which contains native
silver As The first workings in the shaft
gave rich assays of gold and silver, their
ores must be very rich. They are now
erecting smelling works on large scale,
and being men of energy, competent and
qualified, and backed up with a very rich
mine, there ia no doubt of their success.
There are other mines here similar to the
Roulstone & Bates property, one espec-
tally that has been prospected to some
extent, and ores shipped indicate it's
value. The vein is very large, and plenty
of ore in sight, and plenty of water for
reduction works at the mine. Most like
" there are other men like Roulstone and
Bates; let such men come on, they can
obtain the property on terms to suit.
