South Dakota Mining Company.


The Financial and Mining Journal OF
Aug % contains the following rospectns
ofthe organization and operation of the
South Dakota Mining Company;
The South Dakota Mining Company
This is the name of a comparatively new
mining venture that promises to be-
come public favorite. 1t was organiz-
and incorporated in March, 1890 with
a capital stock Of $1,000, ,000--or 200,000
shares each Of the par value of $25 with
its business Office at 535 Pearl street In
New York. The location of the proper
ty is at or near Moss City, South Da-
kota, and nearly 100000 have been ex-
pended, as we are assured in develop
ments and plant embracing a ten
stamp mill. The property, also is a
very large one embracing as it does 2l6
lode claims with 5000 acres Of placer
ground. Besides the ten stamp mill
used there is another one of twenty
stamps employed in developing the
property, besides other machinery and
appliances which are under construction
that viii cost fully 100000. The proper
" is understood now TO be in the hands
Of a company with ample means for it's
exploration and exploitation in the
most thoroughly systematic and ener-
getic manner, both with respect to its
placers and quartz veins, the quality of
which may be judged from the extracts
that follow from the report of the
anentei Riotte, as late as June Goth,
1890.
1--WE received of you three sacks Of
ore for free mill test. We crushed,
sampled and assayed the same. and it
contains as per assay No. 95l2; Gold,
S3l per ION silver trace.
I'VE put the ore the through No, 4
slot screen, wet by bathing, and caught
the free gold on an electro plated silver
plate. The yield was 10. 8 grain fine
gold, valued mt SO S525.
This is equal to yield of 1924 per
ton of2,0O0 pounds. The tailings from
the stamps were caught, sampled and
assayed, and proved to contain as per
assay No. 95l3: Gold, 5000 per ton !;
silver, trace. ~,
we passed these oyer Golden Gate
concentration and saved rs pounds, or
81 per cent, or at the rate of io2 pounds
per ton. These were dried, sampled
and assayed and found TO contain as per
assay No. 95l4: Gold. $70.1S per ton Of
concentrates silver. l.S OF. per ton of
concentrates.
"The tailings from Vanner were
caught campbell and assayed, and prov
ed still to contain. as per assay No. 95l5
Gold, $l4.47 per ton silver, trace.
The ore will Weld almost all its gold
if pulverized fine and dry. The gold
left in the tailings is contained as fine
free gold enclosed in particles Of brown
hematite, the product Of the decomposi
ton of iron pyrites.
Roasting and chiorination will also
extract the gold, but at higher cost.
Very respectfully,
Z. n. RIoTTE, Manager.
The Deadwood Pioneer Of Tuesday,
the 2Sth, comments on the above as fol-
lows:
WHERE is IT, AND WHAT NINE Is 1T?
The following brilliant prospectus in
the Financial and Mining Journal, Of
August 23d. Diligent inquiry here has
failed to elicit any information. Ac-
companying the article are elaborate
cuts of mills, tramways, etc, but the
scenery indicates that they are located
out on the prairie.
For the benefit of the mining editor OF
the Pioneer we suggest that he prosecute
his inquiries outside of Dcadwood Gulch
If he will take the train for Custer
some afternoon, we will, after his ar
rival, and before the next train departs
for Deadwood. drive him to spot just
about four miles west of Custer where
the mining company in question has
spent thousands of dollars in develop.
ing mines, building and operating mills,
etc. The improvements referred to so
doubtfully by the Pioneer are all there,
and in addition he will find large
force Of men erecting new buildings, re-
pairing old machinery, and putting in
new. AS regards the work done by the
company in the past, the ore taken
out and the results Of assays made, Robert
B. Moss, mining engineer of Four
Mile has in his possesson papers that
are ample proof of the correctness OF
every statement made in the article in
the Journal. Come down and see us
gentlemen of the Pioneer, allow us to
show you around and then admit that
your conclusions were too hastily ar.
rived at.
