from claim recently located by Alex
Madill, w. w Challis and Alex Smith,
II miles east Of this place, was left at
this Office on Monday The lode. known
as the Jumbo" is two feet wide, and
a thorough tes; ofthe ore has determined
the fact that it carries SO per cent of this
mineral. This mineral has been FIRE
quentIy encountered by prospectors in
this district, but the quality Of the ore
has been inferior, and as a consequence
little attention has been given it. The
quality Of the ore found in the Jumbo
is much purer, and will doubtless prove
TO be Of valuable character. A sample
Of the ore has been sen, to the Dixon
pencil works with. a view to the deter
mination Of its commercial value.
ANOTHER CYANIDE METHOD.
Experimental tests are being made at
our state School Of Mines with the above
chemical, which is certainly new and
novel. The ore is first crushed 10 the
desired sire ard me pup pnt INTO re-
volving barrel together with the cyanide
solution and certain quantity Of mer-
curry and zinc in the form Of amalgam.
The barrel is then closed and allowed
to revolve for a specific time The pulp
is then removed and the solution drawn
off To be used over again, the gold and
silver contained in the ore being recov-
cred in zinc amalgam. Tests already
made show a recovery Of IS per cent of
the assay yalue.-Times.
RUMoR
There is report current that there is
q prospect of a change Of ownership 10
the Keystone mine. We know nothing
definite Of the truth Of the report, but
D men of enterprise in the southern
Hills will hope it is true. The mine it.
self is no doubt bonanza, but the man.
agement has been hampered from the
beginning, by lack Of capital, and Of
unity Of action. Given sufficient capital
to develop the mine properly, with an
aggressive economical management, and
the Keystone will prove a source of
wealth to its owners, and an eve opener
to capital, Of the wealth Of the great
gold belt of the southern Hills.-Tin
Miner.
LADY GAY.
Supt. w. A. Logan of the Lady Cav
mine, returned from his eastern trip last
Sunday morning. During his absence
he purchased an engine and other ma
chinery, necessary for the successful
working Of the mill on that property,
which it is expected will be put in place
within the coming month. This com
pany will be fully equipped with a good
plant, ready to start with the season of
'9i, to do good work. The ore they
have always with them, in good quantity
and excellent quality. Good reports of
their workings are among the certain
ties of the future.-Tin Miner.
THE KEYSTONE.
Notwitnsranning the statement made
some days ago that the Keystone had
started up, not wheel has turned,
neither will there be a move in the mill
for perhaps month The hoisting plant
has been rebuilt and is in shape for use.
Fonr men are employed drifting on the
lower (l00-footl level toward the vein Of
ore. This work was in progress when
the fire occurred, but was necessarily
discontinued. They expoct to encounter
the vein within forty feet, which will
require several weeks work with the
small force. Times.
NEW AMALGANAroR.
New devices for the extraction and
recovery Of the precious metals are Of
late becoming verv numerous. The
latest is an invention Of citizens of New
Mexico, the Albuquerque Citizen has
the following to say about 1t: &C.
OConnor Roberts and Chris Lamporter
of this city have been busy for the past
two week in perfecting a gold extractor
and amalgamator and this days mail
carries to Washington their application
for a patent. 1t is claimed that the
machine will save the finest -four gold
as we'll as the coarse grains, and that
placer dirt or the pulp from stamps can
be worked as low as fifteen cents cubic
yard, and that the machine will save
one hundred per cent Of all free gold no
matter how fine.
THE CALEDONIA.
About 20 men are now employed on
the above property in running drifts
and sinking the double compartment
shaft so feet deeper to connect with an
upraise from the 600-foot level, 10 be
made from drift from the Giant and
Old Abe workings. Connection was
made some days ago with the same
workings on the 500-foot level This
work is purely prospecting and. accord
ing to one of the men employed. the
finest body Of ore on the belt has al
ready been opened up, with every indi-
cation of its being extensive. The work
now under way is being done with pow.
er drills. compressed air being utilized.
The hardness of the rock may be i'm
agined from the fact that some Of the
shifts have only been able to drill II
feet, showing it to be harder than cast
iron. report is current tha. when the
company resume operations the ore will
be crushed on the Lead side of the
divide and all the mills now in Terra
vile moved to the plot of ground near
tho settling dam on Gold Run. recently
purchased from ]. III. Skeiiy and James
Connors.--Times.
