The Globe Mining Company has or
,orod a new hoist, pump, air compress
az and drills, and is preparing to
ink to a depth of 1000 feet on it's
.ronerty a short distance west of Lead.

a. vast amount Of mineral land in the
Hills, the acreage running up into the
+housands. Heretofore the work has
heon confined to tunnels and c~rosscuts
tcwards the top Of the hill, where low
Grade. free-milling rock has been dis
royered.
The Grantz Gold Mining company is
An,shing it's new assay Office. at the
Roosevelt group Of claims, recently
purchased, and Jesse Simmons Of
neadwood, a graduate of the South
dakota School of mines, has been en-
eageG as assayer. The Office is a COM
modious frame structure, two stories
figh. and will contain a complete la
boratory, as well as a company office
and sleeping apartments for it's Off
cers The shaft of the Roosevelt
group is seventy-ive feet deep. After
an additional depth of twenty-five or
thirty feet has been gained, a cross-cut
will be driven to the ledge, to prove
the ore body. If it is found as strong
and rich as it is at the outcrop, a steam
hosting plant will be installed. The
shaft the company is sinking on the
did St. Elmo group is 113 feet deep. and
a station is being cut.
Another discovery has been made
On the ground Of the Columbia Mining
company, near Rockford, the second
within ten days. The second discov-
ery is about a mile from where the
rich strike was made the fore part of
the week, and, while the ore is not SO
rich as that first discovered, it appears
to be in larger body and to carry uni
form free-milling values. 1t was made
in a tunnel that has been under way
for several months, and is evidently
the vein from which ore was mined
twenty-five years ago, to supply the
old Charter Oak mill, the first quartz
mill to be erected in that part of the
Black Hills.
Shaft-sinking has been commenced
on the ground Of the Deer Lick Gold
Mining company, six miles north Of
Spear1sh, along Iron creek, west Of
Spearfish canyon. The company has
done several thousand dollars worth
Of work on the property, all Of it in
tunnels and c%rOss-cuts from tunnels,
with the result that much ore of good
grade and adaptable to cyanide has
been revealed. The new shaft has
been started on a vertical of rich ore,
that is found coming up through the
formation. The property has been ex-
amined by competent mining men, and
has been praised by oil of them. Ev-
erything is highly m~ineralized in the
immediate vicinity, and the Quartzite,
where exposed on the surface, assays
better than 81 per ton on an average.
There is believed to be sufficient ore
IN sight to justify the erection of a
plant for its treatment, and the COM
pany hopes to be able to build early in
the spring.
Alarge body of $12 ore has been dis
covered on property belonging to Hen

schneider, adjoining the ground of
tne Deer Lick company on Iron creek.
MI. Schneider ~ the original owner
Of the tract, comprising ten full claims

terests with him two years ago.
