Deadwood, S. D., April 2.--The cyanide
plant Of the Imperial Mining company has
completed it's first years work. After
solving more problems in mechanics and
metallurgy than confront most cyanide
plants of the Hills, it has been adjusted to
satisfactory and profitable basis OF op-
GRAFTON. - ---- -s--- s..-,.t
The mill is Of a type new to the South
Dakota mineral field. It is built on a
level, instead of being terraced on hill
side, and mechanical appliances are used
for the conveyance of ore from one depart
ment to the-other, it having been held by
it's originators that this plan possessed ad-
vantages over the plan Of handling the ore
by gravitation. The designers OF the
plant were not familiar with the degree of
hardness in Black Hills ores, and conse-
quently the capacity of the plant was
found by actual test not to be as great as
intended, the rolls being unable to reduce
the rock to a fine mesh as rapidly as they
had been scheduled to do.
It is supplied at present with better
grade of ore than it received the first few
months, and material improvements hav-
ing been made, it is able to handle its ore
with greater dispatch.
The plant has received much custom ore
for treatment during the year, and has
returned the owners of the ore liberal
profit. At present it is running exclu-
sively on ore from the Imperial mines,
treating a little less than 100 tons a day.
Attorney William L. Mclaughlin has
been elected general manager Of the
Horseshoe Mining company. succeeding
Charles Allis, president of the company.
He has also been elected a member of the
board Of directors and secretary of the
company, his election taking place at a
meeting Of directors in Milwaukee. Mr..
Mclaughlin has returned to Deadwood
fully authorized to take charge of the
company's affairs and operations. Min
| ing will be resumed at once and the ore
shipped.
| The promotion stock of the company,
about 100000 shares, has been placed In
trust in Milwaukee, and the 5000, 600
shares that have been issued from the
treasury, with any stock that may here
after be issued, have been preferred to
the amount Of 1 per cent a year.
At the meeting Of stockholders, at Beu-
lah, Wyo., April /, the shareholders will
vote on the proposition to issue $4,000
in per cent bonds, to provide money for
completing the improvements now under
way. f.. -.
The Lucille mine is to be started April
and the ore will be sent to smelters al
Omaha and Denver.
