About Custer.
Custer, S. D., May 29.-The skill, rare judg-
ment and good luck that have attended Otto
P. TIL Grant, in his mining operations seem
to have followed him into the southern Black
Hills and bid fair to put the holdings of the
Grant, Gold Mining company into the list
Of dividend payers sooner than was thought
possible. vein of free gold ore is exposed
on the old st. Elmo ground belonging to the
Grautz company that at q depth of twenty
two feet is five feet wide and gives S52 ton.
1t is a true assure and is increasing III width
as 1t goes down. A new double compartment
shaft is being put down with two shifts, and
hosting plant capable of going down 1000
feet is to be installed. A level will be eStab
hshed at 300 feet, and the ore fully explored.
There is a comparatively new en-stamp mill
on the ground. The stamps weigh 800 pounds
each, and have ninety drops per minute This
will be put in comnmiSsion soon as the
proposed cyanide annex is completed. Lum-
Der and mining timbers are being delivered
on the ground. and a clearinghouse ore
houses, blacksmith shop and other necessary
improvements are being built.
The company has recently purchased an ad-
6itional $50 acres seven miles northwest Of
Custer, on which a rich assure vein of gold
bearing has lately been opened. Eighteen
samples gave returns of S65 per ton. Miners
are now extracting ore for an initial ship
ment of 100 tons to Denver, The lower grade
ore will be left to be treated by another mill
to be erected.
The Penobscot Mining company has struck
new body of ore near Garden City. 1t runs
as high $35 to the ton, with general aver

@. P. Ankeny, NJ. H. Lyon and Others who
have the bond on the Kicking Horse group of
claims, on the Blacktail gulch divide, have
unwatered the mine and an examination is
now in progress in the lower workings. The
Kicking Horse is one Of the best developed
mining properties in that section, and has
several large bodies of low grade cyaniding
ore opened sufficiently for production.
The Rossiter cyanide plant in Deadwood
Is showing excellent results on ore from the

1t is treating fifty tons a day. The plant is
under lease to John Lundberg and J. v. N.
Dorr, the latter being in charge of the mill
while Mr.. Lundberg conducts the work at the
mines.
Two important free gold strikes have been
made near keystone. One was on a fraction
owned by E. II. Flynn, the side of Mount
Aetna, and only about 300 feet from the Holy
Terror. The ledge is revealed by a shallow
trench, and nothing can be determined to
its extent, but it shows free gold and pans
nicely. 1t is on ravine famous in the early
days for rich placer. 1t is only twenty rods
long and 1t produced $4,000 in dust. Upham
Hayward, owners of adjoining claims, have
set a force at development work, as the ledge
on Mr.. Flynn's fraction bears directly across
their group. W. E. Gerard made the other
