reason of certain difficulties encounter

time, just how long cannot be definite
ly stated.
The recent phenomenal discoveries
ofslliceous ore, which have extended
the area Of its occurrence one hundred
square miles, is arrousing an interest
among men OF every vocation that has
no precedent in Black Hills gold mining.
Location certificates are coming into
the register ofdeeds Office at the rate
of twenty day, and Mr.. Mattson. the
recorder. informs the Review that
women as well as men are out over the
hills in large numbers locating claims

THE OLD CHARLIE.
Operations are being continued at the
Old Charlie mine, with encouraging re-
suits. The work Of sinking is still in
progress in the main shaft which has
now reached depth Of about lS0 feet,
which will be increased to 800, or if nee
essary to the more satisfactory develop
ment of the ore body, 400 feet, night
and day force being now employed,
which will be continued indefinitely.
The new Sutherland mill, which was
brought out from New York for expert
mental operation upon the ores Of this
mine, while it has proved to be success
ful in the main, is found TO be suseept-
ibie Of certain minor improvements,
which, in due time, will be made, when
the same will be placed in operation.
In the mean time the stamp mill owned
by the company will be utilized, five
stamps of which will be kept ia opera
tion during the day time for the re
duction of the ores extracted in sinking
the shaft to greater depth. There is
strong probability Of union Of the side
veins on this claim with tie main vein
at greater depth, which will largely in
crease the magnitude Of the ore body,
in which very probable event, new
reduction plant of large capacity will be
placed upon the mine, the mine itself
being an unfailing source Of water
supply which is conceded to be sufficient
to meet all requirements.
THE CROWN NINE.
The work of taking down the machin.
cry Of the old Grand Junction mill pre-
paratory to its removal TO the Crown
mine, situated about two miles up
Spring creek from the Grand Junction,
is being vigorously prosecuted, force
of thirteen men being engaged in taking
down the machinery and in completing
the road over which it is TO be trans
ported. The road is almost completed,
and as soon as the grading Of the mill
site on the mine has been finished, the
mill will be erected. The mine is said
20 be very promising free milling
pr rnposition of the low grade order, but
with the splendid facilities at hand can
be made to pay handsome margin Of
profit. The plant will be run by water
power, the water being carried to the
mill by means of fume from Spring
creek, mile and quarter distant. The
cost of mining and milling the ore, with
the facilities at hand, will, it is said, not
exceed fifty cents per ton. The ore car
ries from 81 to 81 per ton, and the
quantity is said to be comparatively
inexhaustible. The enterprise promises
to be an important one, the success Of
which, now conceded means much ben
eft TO this city and to the Black Hills
at large. A. D. Steward. Of Deadwood,
has charge Of the management Of the
preliminary work, and is pushing it to
completion with all possible dispatch.
GOLD HILL GROUP.
The following careful and conservative
description Of the above group of gold
claims, as reported by correspondent
of the b. II. Mining Review, after
most thorough and painstaking exsmin.
alton of the property, appeared in late
issue of that paper:
The Gold Hill group of mines, con
sis,ing Of 81 quartz claims and 90. acres
of placer ground, or 24S acres in all,
situate nine miles northwest of Custer
City, is probably among the most prom
inent gold properties in Custer county.
The group is now under bond TO A. -.
Stewart and associates and no pains or
money will be withheld in bringing this
property to the front. That its posi-
bilities merit great confidence can be
Judged by the opinions expressed by
practical mining engineers who have
several times visited and carefully in
yestigated the ground. One Of them
Saws there is q network OF auriferous
Quartz veins. On some of the claims
are already discovered and opened, one,
others two, others three or more veins
are in sight, and so far as developed
nearly all are vertical. The micaceous
slate represents a value OF 4.79 per ton
of ore, while the refractory ore goes
1898. Ninety per cent of the 81 70 ore
can be recovered, or a net of $4.3l, but
of the refractory ore only So per cent
and of the 80 90 ore $844 net. The
operation reqnired TO obtain the metal
god is, that all Of the aurferous states
should be carefully assorted and treated
separately by the stamp mill process;
the refractory TO he treated by q seper-
ate stamp mill, the free gold collected
on amalgamated copper plates, the re.
mainder T. concentrated and pre-
pared fo' smelting, chlorination
or the q 's.
