WEEKLY MINING RESUME
More Good Ore Encountered
at the Bunker Hill.
Contract Let for the New Mill at the
Kennedy-Central Eureka and
Gwin Pay Dividends.

Kennedy-Central Eureka and
Gwin Pay Dividends.
DEFENDER.--A ten stamp mill is to
be erected on this, the deepest and
most productive mine in the Pioneer
district. With the four-stamp at
present on the property, the yield is
about $1,000 per month, with one half
that amount clear profit. With a
modern 10-stamp mill this output can
be trebled. The richest portion of the
ore is rebellious, and cannot be worked
to advantage on the ground. 1t is
shipped to Selby's reduction works for
treatment. The success OF the De-
fender ought to have very stimulat-
ing effect upon the mineral develop
ment OF the eastern section of the
county. That region is rich in gold
bearing seams. 1t doesn't require a
large fortune to operate in that dis
trict. 1t is the poor mans field. 1t
has made no millionaires it is true. but
a number of snug little fortunes have
been taken out by the expenditure of a;
small amount of capital. Aud the min
eral territory is long way from being
fully exploited.
EDINBURGH.-We were shown this
week by David Fisher, superintendent,
samples of rock recently taken from
the Edinburgh mine, near Wieland.
They are running tunnel on the vein,
which is about 8 feet wide. The ledge
is divided into two kinds OF ore, called
the banging and footwall ledge, each
having distinctive characteristics. A
piece of rock from the hanging wall
was broken up, and showed free gold
sprinkled throughout. 1t was taken
from depth of 100 feet from the surface.
Its value consists almost exclusively of
free gold, scarcely any sulphurets
showing in the ORE. No assay has been
made, but its value is variously esti-
mated from $50 to $500 per ton. The
sample was of course selected, and it is
not expected that the body of the ledge
will average anything like the figures
stated. The ore met with on the foot
wall is of very different character;
judging from the sample we have be-
fore US. 1t consists of three-fourths of
its weight in sulphurets of between
silver grey and copper color, and inter-
mixed with a black -colored mineral.
Its gold bearing qualities are unknown,
as no assay has been made. 1t is be-
lieved, however, that its gold value is
high. The promoters of this mining
venture are elated over the prospects.
The tunnel is being run by contract,
the rate of progress averaging about
two feet per day.
BUNKER HILL. Samples of the ore
accidentally blown off from the ledge
which runs alongside the drift at the 800
foot level, are on exhibition at the store
of E. GinOcchio & Bro. They are indeed
wonderful specimens, and have attract
ed many visitors during the week. Two
pieces OF quartz are shown, both
literally sprinkled with free gold.
Rock of this grade would yield, at
rough estimate, thousands of dollars
per ton. The vein is reported to be
two feet wide at the point where this
rock was taken out. On Tuesday last
another strike was made, this time in
the face of the drift at the 500 foot
level. Ore said to be even richer in
free gold than the samples above re-
ferred TO was blown out. The fact
that it came from the face of the drift
would indicate either that the vein is
widening or changing its course. At
the l4OO level the ore body is rapidly
improving. In fact, the quartz met
with at this depth is valued at from $40
to SIS per ton. Allindications warrant
the conclusion that the Bunker Hill
will develop into one of the most liberal
gold producers OF the county.
KENNEDY - The contract for the
erection of the new mill between the
east shaft and the old works, was let
last Monday to the Fulton Iron Works
of San Francisco. Twenty stamps will
be finished to start with, and the mill
ing capacity increased to 80 later on,
as the underground developments de-
mand. The ore body is of immense
size, over 100 feet wide in the lowest
level. Taken altogether, it is low
grade proposition. The average will
not much exceed s. per ton, but with
this character of rock a handsome
profit can be made with 100 stamps in
motion. 1t is estimated that with this
number of stamps, there is ore enough
blocked out to run for l6 years. The
running expenses OF the mine have
averaged about s26, 600 per month for
several years, almost from the starting
Of the east shaft, and this outlay has
been met by the output of the mine,
without calling upon the stockholders
for assessments. A contract was also
let last Monday for the erection of the
new hoist over the east shaft. The
Allis Chalmers Go. of Chicago were
the successful bidders. This hoist will
eclipse anything OF the kind nov in the
county, capable of extending the works
