shaft has been Bunk 70 a depth Of fifty feet
on the same vein. and samples taken ct
different depths. the average assay return
OF which is 21O.50. A contract has been let
70 sink these shafts to a greater depth and
crosscuts made TO ascertain the width OF
the vein. which on the surface is a large
one. The Provo is another group belong
ing to the company embracing about 100
acres Of mineral ground. This ground has
not received very much development. the
most extensive being a shaft which has
been sunk on the vein for a depth OF
twenty-five feet. Good assays have. how
ever, been received from the ore tested
taken from the shaft, so a contract has been
awarded to sink # fifty feet deeper and
Their TO crosscut the ledge. The London
group. situated about three miles west from
Custer City. is perhaps the most valuable
group owned by the company. and en-
braces an area Of 300 acres. a large part
OF which lie choice mineral ground. AS a
free milling proposition the London is
probably as rich as any group Of mines In
the southern Hills. The London has re-
cetved a great deal Of systematic develop
ment and is in good shape to receive a
treatment plant. and It is the intention Of
the company TO erect upon Il a ten-ton
stamp mill this spring and later on to add
either a chlorination plant or a cyanide
annex. Work on these improvements will
be started by the company just as soon as
the weather conditions will permit.

SHERIDAN. S. D.. Feb. s.-tspecial)-
This camp and the copper camp at sher-
idan hare been connected by telephone, so
both places are in communication with all
the principal towns Of the Hills. Sheridan
Is getting to be one Of the ~liveliest camps
In the Black Hills. the Maloney Blue Lead
and the Dakota Calumet company employ
ing a large number Of men in their opera
tions. Last month, besides the other work
accomplished. the miners on the Blue Lead
drove 1856 feet Of tunneling, and for part
Of the way through the hardest kind Of ma
terisl, IL taking three shifts to put in one
round Of holes. The southeast drift from
the main tunnel, which is being run toward
the ore deposits exposed on the surface OF
the ground 500 feet above, is rapidly ap-
preaching a point which will be directly
underneath them. and the material now
coming into the working is mixed with a
good grade Of copper ore. 1t is expected
that the ledge will be reached in about
three weeks at the present rate Of progress.
The company is putting in 600 feet Of air
piping and making other arrangements to
run power drills in the workings. the face
OF sorle Of which is at least 1000 feet from
the portal Of the main working tunnel.
The Mount Aetna Mining company has
the three-compartment shaft which Il is
sinking on the Lucky Boy down to the iSO-
foot level. From this level a drift will be
run to intersect the ore body exposed In
the tunnel 100 feet nearer the surface.
This ore body, a vertical. where it has
been opened up in the tunnel is very rich,
and some think thR' it will rival the Holy
Terror. which mine it is near, In the same
district. Hosting, so far, has been done
with a steel bucket, but cars and cages
have been ordered, and as soon as they
arrive they viii be installed in the shaft.
After a station has been cut on the 100
foot level and a drift started sinking will
be resumed in the main shaft and con-
tinued to a depth OF 500 feet.
