DEADwooD. s. D., Oct. 26.-tspecial)-
Il is probable that there is not at the pres
ent time a piece Of development work in
progress in the ~sllicious ore belt. OF the
Hills fraught with greater Importance than
that on the property Of the Cleopatra Gold
Mining company. For four years past this
company has gone on quietly with the work
OF opening up its holdings on Squaw Creek,
midway between Carbonate and Ragged
Top, and has expended a large amount Of
money. The development Of the upper ore
bearing contact alone amounts to over 1000
feet Of tunnels, opening no less than four
teen well-johned v~erticals OF ore. From
six Of these v~erticals ore has been milled
in the c~ompany's cyanide plant on the
ground. This was one OF the first cyanide
plants erected in the Hills, and, II the
little plant at Spearhsh be excepted, the
nrst to successfully treat the low grade
s%llcious ores with coarse, dry crushing,
BOW so successfully conducted by the Wasp
and spearhsh companies. At the time the
Cleopatra company took possession Of its
FIRST purchase on squaw Creek. there was
RAebNAtoAAs 80 SAh IL NAUN eNAAN
and many mining men OF the country hest
tated to predict that the profitable ~silicious
district would be. found to extend so far
north and west, but time and work have
fully justified the faith Of the Cleopatra
management, until at the present time
this property is no longer on the outskirts
of the well known siliclous belt. The COM
pany has gradually increased Its holdings
from time to time, until now it controls
o large block OF ground. The most i'm
portant work under way at the present
time is the completion of the company's
main shaft to the Quartzite, for the pur-
pose OF exploring that contact. The col
lar Of the shaft is about forty feet above
the level OF the creek, and the shaft has
a present depth OF about 230 feet. OF this
distance about eighty feet has been through
. q hard porphyry and the remainder through
shale. Seams, vertical. or nearly so, have
been encountered in the shaft from time
TO time, and these have invariably pros
pected more or less.
Now in Red Sandstone.
The present bottom Of the shaft lie in a
red sandstone, which is the formation i'm
mediately everything the quartzlte. 1t may
be assumed that drifting on the quartzite
will very soon be commenced. The loca7
zion Of the shaft is near the line Of some
Of the vertioals disclosed on the upper
level Of the mine, and In a basin between
Immense dykes of porphyry on the east and
west. Naturally, property owners on all
sides are watching this development with
interest, and the conditions are such as to
make 1t seem probable that the very best
place has been chosen for determining the
fact of the existence OF the quartzite ores
for a large district. Every indication is
extremely favorable for the development
OF a great mine on the company's ground,
and, in addition to this, a great increase in
the value Of all surrounding property. Syl-
vAnite ore was first Identified on the prop
erty adjoining the Cleopatra, the Iron
sides, owned by the Colorado and Dead
wood Mining company, and there is good
reason to believe that such ore will be
found here in Quantity.
Immediately adjoining. the Cleopatra on
the east [. the old Pocahontas, in which a
small vertical was discovered years age
yielding very rich ore. Nearby is the Iron
Hill. which has yielded 1878. 900, the Sea-
bury-Calklns, which has also turned out
rich ore, and the Spanish R. When it is
considered that the output of these mines
has been obtained from the upper con
facts. end their developments have never
reached the quantities., the formation or
which every experienced miner OF the
northern Hills believes the best and largest
bodies Of silicious ores lie, the vast i'm.
portance to the district and to the Hills
OF this quartzite development on the Cleo
patra may be in a measure appreciated.
Prospects Are Good.
The Golden Treasure is the name OF q
new mining company, composed of Edger,
ton, o., people, which has been organized
for the purpose of working a group o.
claims In the Bald Mountain district. Tn,
company's holdings are in a good location
In a district from which much good or,

took possession of the ground two
weeks ago. began operations by follow,

shaft. which Is being sunk. is down abou
twenty-seven feet on the vein, and at tina
depth Il has widened out so that IL NIL

growing stronger. The ore which is car
ried by the vertical is phonilitic. and from
assays recently made will go from $40 1
t43 a ton gold. The company has bee

and will ship 1t to one of the Deadwoo,
plants for treatment.
The Rossiter cyanide plant, which ha
been running for the past fifteen days o.
ore from the Rattlesnake mine in the Bar
Butte district and on ore from the Bux

in the Hills and was recently leased b
