Mining Items.


we learn that all the machinery for the
new Griffin mill has arrived and is
being set up. The contractors have
about ten feet more to sink on the shaft.
The ore is ten per cent higher grade
than it was before the present depth
was attained.-Pioneer.
The stockholders of the st. Elmo NJ.
& NJ. Co. are feeling jubilant over the
result Of development work now in
progress on the property. The vein is
becoming larger with every foot Of
depth and continues to hold its own in
grade. j. G. Mcdonald. superintendent,
is slowly recovering from his late acci
dent, though he is not yet able to par
ticipaie in the work he is at the mine
directing operations.
| The largest solid gold nugget ever
found was taken from the Byer & Halt
man gold claim at Hill End, Australia
May 10th, 1872. A correspondent Of the
Mining and Scientific Press thus de-
scribes it: Weight, $40 pounds; height,
four feet nine inches; width, three feet
two inches; average thickness, four
inches; value, Sl4s,o00. 1t was found
embedded in thick wall of blue slate,
at depth Of 250 feet from the surface
Ira Gilman has secured the lease Of
the twenty-stamp mill at Puma 10
make practical test Of his new method
for the recovery Of precious metals from
their ores; laboratory tests show it to
be successful. Should it prove CONNER
cially so it will be one Of the most
valuable discoveries of the age Mr.
Gilman has been at work upon it for
years and believes he now has it per
fected all characters of ore can be
treated at nominal expense. Both the
gold and silver being recovered at one
operation. His first run will be on
silicious ore.-Times.
BY the Mofatt process, it is claimed
that 80 per cent Of the assay value both
in gold and silver can be recovered at
an expense of $3.50 per ton. A com.
plete plant Of "a tons daily capacity can
be put up for $4,000, and all characters
of ore are susceptible to its treatment
The main principal being the thorough
oxidation Of the ore, after which the
pulp passes into amalgamating pans
Arrangements have been made TO put
in one of the machines at Lead and
operate it on the concentrates from the
Homestake mills. 1t is quite compact,
occupying a floor space of 8 by l2 feet
and requires the attention of but one
man. 1t is expected to have it in oper
alton next month.-Times.
MINES BONDED.
The Gold Hill and Maggie gronp ol
gold claims, embracing twenty locations
on the Penobscot belt, six miles west oi
this place, were bonded this week to an
eastern company. A number Of the
claims have been sufficiently developed
to determine their character and value,
| while many OF them have never been
disturbed to any material extent by
pick or drill. The consideration, a
small portion of which was advanced,
while it is known to be large amount,
has not been definitely stated, and for
reaso which may never be known,
the time allowed for final payment is
religiously withheld. The property is
mainly owned by William Rosenbaum,
Paul kleemann and Charles Harbach,
of this city, all of whom are old pioneers
of the southern Hills who richly de-
serve all the good fortune which may
come to them, and who will receive the
heartiest congratulations Of their friends
in the event of favorable termination
Of the important deal.
THE MArcHLEss GROUP BONDED.
Frank Hebert has bonded the above
group, consisting of five claims situated
on Bear gulch. to Messrs. Hulst & Price,
of Rapid. From Mr.. Hebert the News
learns that work on the claims will i'm
mediately be commenced to develop the
property and that il, at the end of three
months. the company should want more
time to prosecute work, the same shall
be given, after paying certain amount
Of the purchase price to the owner for
the further privilege. The surface pros
poets on the claims are good, and the
indications are such that this property
will develop into q mine.-Hill City
News.
A YEAR OF GREAT RESULTS.
The mining results in the Black Hills
for the current year are thus summed
up by the Black Hills Mining Review !:
"A year of great results, We believe
will justly Apply throughout southwest
ern South Dakota for the year 1895. An
approximate amount Of ore that will be
mined and milled during the season will
suffice to give some insight into the i'm
mense magnitude Of our mining industry.
Ore mined and milled at Lead, Terra
vile and Central, daily, 1900 tons; ap.
proximate cost of mining and milling So
per ton; total, 800. Daily output Of
ore at Bald Mountain and Ruby Basin
400 tons; approximate cost of mining,
transportation and treatment $40 per
ION, total. $4,000. J. R., Summit and
Grizzly Bear mines, near Hill City, when
the mills are operated at full capacity.
which they will be doing by the middle
Of the year, will consume 400 tons daily,
at q cost not to exceed 81 so per ton for
mining and milling, or Q total of 81 900.
The milling capacity OF the Keystone
mills at the present time is about $50
tons per day, but with the present pros
pective enlargement, there can be no
accurate estimate on the years increase,
but from the volume of ore already
blocked out in the district Of profitable
grade, 1t would not be surprising to see
the milling capacity increased to 500 or
even 1000 tons per day. By placing
the daily average for the year at 800
tons at cost Of $3.50 for mining and
milling, would make pay roll Of $3.50
per day. At Four Mile, near Custer, the
output can be safely placed at 40 tons,
at a cnst of not over 50 so per ton, which
would make . daily pay roll Of 500.
From experimental tests which are now
being applied 10 the sulphite aud other
refractory ores OF Custer county, IL
proven exceptionally amenable to treat
ment by the cyanide process. will i'm
crease the output of ore from that coun-
ty immeasurably. A conservative es
