RICH ORE WORKED.
A Process That Promises to Be OF
Vast Importance to the Miners

A Process That Promises to Be of
Vast Importance to the Miners.
Special to the Globe.
DEADwooD, S. D., June 13.-Some
things have taken place in the past few
weeks which are likely to be of vast inn
portance to the mining interests of the
Black Hills. The Chlorination plant of
Garden City has been completed. Sew
eral tons of ore have been run through.
and it has been demonstrated that the
process will work the ores of that vicin-
ity successfully. The first run saved 95
per cent of the ore, and subsequent
runs show conclusively that the ore can
be worked by the chlorination process
with saving of s. per cent on an aver
age. The cost of working is, estimated
on the basis of the runs that have been
made, to be less than So per ton. The
company is now advertising for ore to
be worked in its plant, and it agrees to
work the ore for $13 per ton and save
IS per cent. This is much cheaper all
around than shipping it to Omaha, and
be shipped hereafter to Omaha from
that vicinity. The plant is small, only
ten tons per day, but the company in
tends making some changes which will
increase it's capacity materially. At
present the ore is pulveriZed by means
of stamps, and has, of course, to be run
through wet and afterwards dried. A
Gates crusher has been purchased and
will be put in the plant, thereby in
creasing it's capacity to twenty tons per
day and reducing the cost Of working.
A great deal of credit is due the gen
tIemen who have control of the enter
prise and who have operated it. They
are men of limited means, but they
have staked their all on their faith in
it's success, and we are glad they have
not been disappointed. Among the
number who deserve especial mentiOnis
j. q. Keith, of the Keystone hotel. He
was one of the prime movers and chief
stockholders in the enterprise. The
credit of applying the process to the
ores Of that vicinity is due to W. B. Nc
PhersOn, who is now superintendent
and general manager of the plant. The
experiments made and the results OBJ
tained will certainly lead to further de-
veIopments in the treatment of the re-
factory ores of the Black Hills.
A number of persons largely interested
in mining property here have been in
Denver during the past week watching
the results of the treatment of Portland
ore by the NewberryV Vautin process.
That process purports to save 80 per
cent of the gold and treat the ores at
cost of not to exceed $40 per ton.
Nothing definite has been heard yet
from the gentlemen as to the results,
but information is expected daily. If
the process works successfully it will
create bigger boom in this country
than we have yet witnessed.
Other mining properties are looking
up. The Uncle Sam has made two sue
cessive clean-ups of over $1,000 each,
the result of about fourteen days each,
and less than thirty stamps. There is
talk that the company will soon begin
to operate their. entire sixty stamps.
Iron Hill is again IN demand and has
been changing hands rapidly during
the past two weeks. The furry is due
to the fact that the company expects to
start up the smelter for shOlt run and
to reported rich strike which, how
ever, is not generally credited. Other
carbonate stocks have shared in the
boom and are consequently more valu-
able.
