Mining Items.

The lease runs until March, 1898.
Among the contemplated develop
.ents upon the Keystone mine is said
TO be the extension Of the lower level
to a point 1000 feet from the south end
Of the mine, where a station will be cut
and a three compartment shaft raised
to the surface. a distance of 400 feet.
F. w. and A. Pettibone came in We'd
from the Demereau Mountain
mines at rringle, and report the work
progressing satisfactorily in the tunnel
now being run, with favorable indica-
of tapping the main vein, for
which the tunnel is being run, in q few
days.
The Kildonan mill, at Puma, was
temporarily shut down the latter part of
last week. by reason Of the large inflow
Of water into the company's mines,
which cuts of the production of ore. 1t
is believed that the drainage Of the
mines will be completed in two or three
weeks, when the mill will resume oper-
alton.
The Penobscot group Of ten claims at
Garden City, owned by r. NJ. Maloney.
and under the supervision of Frank
Mclaughlin is apt to prove a veritable
bonanza. There is said to be 100000
worth Of ore in sight in the two tunnels
Two standard gauge cars of ore
a week are being shipped to the Aurora
smelter, a product of seyen tons a day
with five men at work.-Plaindealer.
An effort is being made to establish a
gold reduction plant at Spearfish. The
Mail says that Assayer Schnitzel of Lead
City, is circulating among The merchants
and mining men of the place, explain
ing to them the Daukwardt electro
process for extracting gold and
silver from ores. 1t is claimed that 1t is
the most complete process now used,
and Messrs. Boyd and Schnitzel will
endeavor to interest some of our people
in the matter, with a view to erecting
and operating a plant here. A meeting
of business men was held Friday after
at Mr.. Boyd's Office, where a
full explanation Of the scheme was
presented.
COO LAC PROSPECT.
William Barnett and partner, who
been prospecting west Of, and
near this place, were fortunate in dis
covering a few days ago, what promises
to be valuable placer ground, near the
mouth ofRuby gulch. They commenced
On Tuesday, and were well
pleased with the result of the clean up.
They are somewhat handicapped how
ever by the limited supply of water,
which if sufficiently abundant for
purposes, would warrant a re-
turn of at least five dollars a day per
man.
vERY PLAUSIBLE THEORY.
An expert mining man predicts that
the siliceous ores now being mined in
the Ragged Top region are but the
blossom rock of immense free milling
ore bodies deeper down. The Home
stake mine is cited by the expert in sup
port of his theory, as great depth was
attained by that company and siliceous
ore passed through before good pay ore
was discovered. The Dacy mine at
Ragged Top is being worked with the
belief that this theory is correct, and the
shaft has reached such q depth as to
make this belief almost a certainty. If
il becomes an established fact, Ragged
Top property will be unobtainable.-

ORE NEAR sUNDANCE.
George Berghofer is quoted by the
Sundance Gazette as saying: Il believe
we have the grandest and richest min
ing proposition in the entire Black Hills
right here at our very doors. Some
weeks ago was discovered a four foot
vein of dark fiinty ore, lying on top of
~porphyry and beneath the limestone,
on one of my ranches on the Williams
divide. / have had several assays
made and have returns of $3.50 and
S24 per ton of gold. The vein is of the
blanket formation, and underlays the
entire divide, an area Of seven or eight
thousand acres, enough SO everybody
can get a good claim. l will have a
mining expert here Saturday to ex-
anime the proposition, and if it 10 as
good as ] think it is / will begin work
at once If the assays keep up l will
also have a reduction plant on the
ground Messrs. Keets, Summers and
Grossfield. of Spearish, inspected the
ground last week and all pronounce it a
good prospect"
GOLD MINING IN LEAD.
The Homestake belt of aurifero Gus
bearing quartz is sufficiently developed
to guarantee, with double. the present
milling capacity, or enough for continu-
Gus Operations for at least fifty years.
The system of mining and milling is SO
admirably arranged by the management
of T. ]. Grier that there has been a great
reduction in the expenses of each
separate department Of the business,
accomplished by improved machinery
and the application of every natural
resource that can in any way contribute
to minimize the working cost of mining
and concentration. There are now in
constant operation $50 stamps (this OF
course is exclusive of the 100 stamp mill
across the hill in Terrayillel, which
crush upon an average Of 1000 tons
every "A hours If we take the average
yield Of the ore for 1896 as q basis 10
estimate the value, each days bullion
recovered would amount to $1,000,
$3.50, 800 per month and $1,000, 600 for
year. With the building and equip
ment of the Ellington hosting works in
South Lead, and the interesting Of the
ore body at that point, will add enor'
mously to the capacity of supplying ore
for the mills, aud will undoubtedly
necessitate the construction of other
