MINING IN THE BLACK HILLS
General Situation Animated with Big E1-

SENSATIONAL STRIKE NEAR CUSTER
Prospecting Accelerated by Find
Horseshoe Company to Install
Large Cyanide Plant and
work Begins I'm Red Top.

DEADWOOD, S. d., May 11.-(Special)-
The Horseshoe company at Puma, which
has been making arrangements to put in a
1,000-ton cyanide plant at that camp, has
changed its plans, and the plant which
1t proposes to erect this spring will have
a daily capacity Of 1900 tons. which in
conjunction with the 1O0-ton plant now
being operated will give the company a
treatment plant Of 1900 tons.
The company will put in a 360-stamp
mill. which will have a crushing capacity
Of something like 1900 tons daily, which
will be sufficient to keep a cyanide plant
Of 1900 tons supplied with pulverized ma
tarial on which to work. The plans for
the new mill are about ready and the
management expect to break ground for
IL within the next two weeks.
The company has been induced to change
its plant from a dry crushing to the wet
crushing process from the fact that 50
much of its ores is of a finty nature and
do not work well with rolls, but are more
easily crushed by stamps.
Last Tuesday this plant had a partial
cleanup from a run on 1000 tons of ore,
and on that day deposited with the United
States assay office in this city a brick weigh
ing 522.S7 ounces. worth, to be exact. So
1880. which would give the ore a value
VI HbLltluluR over 30 per ION, Out as lDt
nlant was not thoroughly cleaned up, it IS
estimated that at least 5000 in gold values
were left in the solution and in the zinc
shayings, which would considerably raise the
ore values.
The company owns a large acreage OF
mining land in the Bald Mountain and
Ruby Basin districts. and for years has
been treating the ores from it by the
chlorination process.
Wasp Makes Good Showing.
Wash 2 sent down its regular brick
from Yellow creek on Tuesday. The brick
contained 500 ounces, but as the bullion
from the Wasp contains a good deal of sill
yer its value was but a little over $4,000.
This was the regular semi-monthly clean
uD of the mines cyanide plant, and they
come as regular as the hours, so no par
ticular attention are paid to them.
The mill of the Imperial Mining COM
pany in this city is at present running on
ore from the company's Blacktail mines,
treating but about sixty tons a day, but
this amount will be increased as soon as
the roads are in condition to haul ore. The
plant, a wet crushing cyanide is one Of
this latest that has been built in the Black
Hills and will make. its first cleanup next
week, and as 1t has been running on some
very rich ore, 1t is expected to be a good
one.
The Dakota Mining and Milling com
pany's cyanide plant, and that of the Col
den Reward are running every day, treat
ing about 300 tons Of ore, while the Ros-
sitter cyanide plant. the first one estab-
lished in the Black Hills is pounding away
on ore from Nevada gulch, treating seventy
FIVE tons daily, making four syanide plants,
besides the big Golden Reward smelter, in
operation in the First ward of the city
daily.
New Engine for Minerva.
The 125-horse power engine for the
Minerva mill in Blacktail gulch was un-
loaded Friday and hauled to the mill and
placed in position. The mill, one Of forty
stamps, has been rebuilt from top to bot
tom and will be ready to start on ore from
the mine IN a few days. The Minerva ore
body is a free-milling proposition and has
always paid big to treat. There is an i'm
mense amount Of it and 1t is very easily
mined.
GALENA, S. D., May 11.-(Special)-The
Monarch mine continues to ship rich ore
to the smelter in Deadwood, the last ship
ment, so it is said, going something bet
ter than 1000 to the ton. There is a large
ore body exposed in the workings of the

The old Richmond, the mine which in
the early days of the camp produced so
much rich silver ore, is said to be bonded
to Omaha parties, who will soon put a large
force of men at work on 1t. 1t is now be-
ing worked BY Bart Harris and associates,
who have recently taken out large quanti-
, ties of good shipping Gre.
The drift on the Glover Leaf which was
, started from the bottom of the deep shaft
is now in something like 200 feet and will
z not have to go much further before it con-
meets with the ledge toward which It is
r being driven. 1t was recently purchased
/, by the company which is now working 1T
/, a close corporation-and since its purchase
Z has not only paid for itself, but has paid
q for some very extensive development WORK
and additions to the mill which is on il.
