Mining Items

F. II. Cook left Wednesday evening
for Omaha and other eastern points on
business connected with the Leroy Min
ing and Milling company, of which he is
president. Mr.. Cook reports the Leroy
as showing up excellsntly as, the work
Of development progresses. We under
stand that the company is planning to
equip the mine with hoist, air COM
pressor and electric drills, with power
sufficient to sink 500 foot double COM
partnent shaft A saw mill to cut the
lumber necessary to put up the buildings
will be installed at once. The property
is situated on French creek three miles
west from Custer, and is considered one
Of the best prospects in this section Of
the Hills.
EXTREME MINING & MILLING co.
The future policy Of the Extreme Min
ing & Milling company has been out
lined by the directors of that company.
and it means great deal to this vicin-
ity. Operations upon this property will
begin early this spring and will be car
ried on in much larger way than ever
before The property has been opened
up to quite a considerable extent and
thorough test run made with their ten
stamp mill and it has been shown that
the property will pay expenses even in
the small way in which il has been
worked, and with the disadvantage of
hauling the ore to the mill and doing
all hand work at the mine, also loosing
good values in the tailings which could
be saved by cyaniding We are advised
that it is the intention Of the company
now first to install power plant, hoist
and power drills Second, to continue
development Of the property, and block.
ing out ore. Third, to increase capacity
of present mill. Fourth, the construc-
tion of a cyanide plant to save all values
not found on the plates, and fifth, the
building of tramway for transportati on
of ore from the mine to the mill.
With these additions to this property
it leaves 30 question but what this will
soon become one of the big dividend
payers of the Black Hills. The business
like way in which each step has been
taken by this company has been source
OF great deal of satisfaction to the rno-
pie of Custer, as it has shown that they
have thoroughly understood the situa-
tion, have proven each step as il has
been taken and now, that they are sure
of what can be done in small way, by
making these improvements there can
be no question as TO what the results
will be.
THE aARIPosA PROPERTY.
John Wise returned last evening to
his homs at the Mariposa mine on Slate
creek near Mystic. The property on
which he has been doing prospecting
work all fall and winter consists of eight
claims and is owned by himself and DR..
Wade, formerly of Lead. Since the lat.
ter's removal to St. Paul he has sold an
interest in the property to parties there
which enables the owners now to prose
cute the work more rapidly. Mr.. Wise
informs the News that an air compressor
and set of Liner drills will be installed
at the mine this spring for the purpose
cf running tunnel 900 feet in length
with which TO demonstrate the veins
value and ore body. The claims have
been thoroughly prospected by Mr.. Wise
by shallow shafts on various places and
nowhere has he failed to find gold in
the rock. Numerous assays have been
made, taken from different parts of the
property, which have given returns
from small amounts up to as high as
$1,000 in gold to the ton of rock. Mr.
Wise feels very sanguins that he will
dsyelop paving mine on the property.
