Mining Items.

we are INFORMED tnat development on
a grand scale will soon be commenced
on the Mayfiower mine about eight
miles west Of town:
1T is estimated that the cleanup at
Klondike this year will be from fifteen
to twenty million dollars. The ttlin
district alone will cleanup about two
millions.
Frank Hebert was Ia from Sunday
gulch the latter part OF last week. In
conversation with a CHRONICLE reporter
he stated that his fve-stamp mill was
nearly ready to begin crushing ore from
his mine on Sunday gulch. The proper
ty is situated about ten miles north Of
Custer, and two miles east Of Oreyills in
Pennington county.
From Keystone comes the report that
the cyanide experimenting being done
by the Holy Terror Mining company
under the personal supervision of James
Baldwin, the company's metallurgist, is
proving this process a very satisfactory
way Of treating the concentrates of the
mills. This means great deal to this
section fthe Hills, as there is SO much
low grade ore.
MONARCH MINING CO.
Articles OF incorporation have been
filed with the secretary of state at Pierre
for the Monarch Mining company at
Custer City, with a capital Of 100000.
Incorporators, Milton A. Synder, Freder-
ick C. Graydon and Arthur w. Under
wood.
The property of the above company is
situate about two and half miles west
Of Custer, and consists of three mica
claims, known as the Monarch group,
and owned by Mr.. II. ]. Orr, but under
bond to Mr.. F. G. N. Graydon, of Val.
praise, Indiana. An open cut has been
run into the mountain along the vein
for distance Of 200 feet. The vein is
about four feet wide. and the mica be-
comes firmer and improves in quality
and size as depth is attained. Mr..
Graydon has force of twelve men, and
two steam drills employed in exploring
the property and taking out mica for
shipment. The company expects to
soon have the property in such shape as
to be able to ship a car or more mica a
week. Mr.. Graydon states also that the
company will buy all the mica that may
be offered for sale.
NOT ELECTRO CYANIDE.
III. d. Dibble, Of Mystic, in a recent
interview with reporter for the Pio-
neer-Times, stated that the new reduc-
ton plant recently erected at Mystic by
f. II. Long and associates and generally
spoken of as an electro cyanide plant, is
not an ctro.cyanide plant by any
means. 1t is. he says, an electro chlor-
inc plant, and the process is not new
invention, it having been used in Eng
land more than fifteen years ago. The
patent is on the apparatus employed a
the Mystic plant. Leaving out des
cription of the crushing machinery, Mr.
Dibble says the system is as follows:
There are three tanks of iron connect.
ed by pipes, for drawing from one &c
the other. The top tank is the mixer
the middle tank the converter, and the
last tank the filter. The fine ore Il
admitted to the top of the mixing tani
with salt, caustic lime and water, ant
is thoroughly mixed. Then it passes te
the next or middle tank, and is here
acted upon by electricity, liberating thu
nascent chlorine, which dissolyes thu
gold in the ore. The gold assumes th'
form of chloride, which Is broken ~
and the valne deposited by the electric
current. Gold and silver are deposited
on an amalgamating copper plate or IL
bath of metallic mercury. The filter
or lower tank is used to Separate and
return the spent solution, to be uset
oyer again, thereby saving the sli2h
values that might remain.
