MINING IN THE SOUTHERN HILLS

MINING IN THE SOUTHERN HILLS
General Renewed Activity and Rich
Strike at the Mariposa.
lockwood, July go. Considerable
activity is prevalent down in the
vicinity of Hill City and feeling
of confidence in the: future Of that
locality prevails among the resi-
dents, says the Pioneer-Times.
The Golden Metal mine three
miles east of that city is making
preparations to resume work ON a
large scale. The company recently
took over the Hill City Electric Pow
err and Mining Company, and in a
short time will commence the con-
struction of an electric power plant,
which will cost in the neighbor-
hood OF $4,000. The company APP
propriated water rights and has ev-
cry detail for the project well in
hand. The site of the power plant
will be near the old J. r. mills, four
miles below Hill City. The company
onws 800 acres of mining lands, in
Guiding the Old Summit mine, which
in the past has been very promi-
nently identified as a producer OF
gold ore. On this property is a
twenty-stamp mill from which sew
eral thousand dollars worth of gold
has been cleaned off the plates. The
mill will be overhauled and Home
stake models Of machinery will re-
place that now occupying the build
ing, and the opinion prevails that
In the near future a large force Of
men will be engaged on the proper
ty, mining and milling ore. The
company's power plant will have a
capacity Of 200 horse power, and it
is estimated that the ores with the
equipment being planned. can be
milled for $1.20 per ton. An enor-
nous body Of ore is opened that
runs $3.50 per ton, intersected
with pockets and streaks that yields
$40 and better which will give up
an average, by mixing, that will
prove profitable mining.
Reports come from Mystic that
the iMariposa Mining company have
at last struck the rich vertical they
have been tunneling into the hill
side for and there is great rejoic-
ing in that vicinity. The tunnel
which encounters the rich vein Is
in a little over LOO feet and taps
the vein at a depth of 500 feet.
This vein was opened on the sur
face about three years ago, at which
an air compressor and power drills
We're installed and a tunnel started
in its direction from the level Of
Slate creek. Large bodies of aver
age grade ore are opened up in va
rious places about the property and
the Mariposa gives promise Of becom-
ing one of the leading producers of
the Hills.
The Golden Slipper has opened a
new gold bearing vein of ore, with
in close proximity and running par
allel with the old vein which has
yielded literally and faithfully for
the Black Hills. The vein matter
of the new encounter runs about
$50 per ton, and the resumption OF
active mining operations are prom
ised in the near future. The old
vein gives up ore that runs into the
hundreds, and it is expected that
developments will find the ore OF
the late encounter increasing con.
siderable from what it is at present.
Klein & Burton, whose property
is situate near the Golden Slipper
are engaged in driving tunnel on
the property which is now 300 feet
and it is expected that they will en-.
counter the vein matter within
thirty feet more.
John Truax is putting in steam
hoisting equipment on the Evin-
vale mine four miles east of Hill
City, with the intention of sinking
the shaft to depth of 200 feet. HI
has a most fattering wolfram
prospect, which Pittsburg capitalist.
are negotiating to take over.

men are now at WORK. The tin mil
has been overhauled and ney
stamps and machinery put in.
