Mining Items.

It's own. -Four men are employed sink
ing.
A. M. Fearing. engineer at the Spo-
kene mine, was in town Thursday. In
conversation with CHRONICLE reporter
he stated that the mill is about COM
pleted, and would in all probability be
started up next Monday for continuous
operation. About 700 tons OF ore are
on the dump ready for the mill. For
the present work in the mine will be
prosecuted on the 100 foot level.
We understand that a deal was con-
summated this week by which James
and Thomas Cotton of Lead will become
half owners in the new gold find re-
Gently made by j. q. Carr and sons near
Four Mile. BY agreement the Lead
parties are to sink a 100 foot shaft on
the property for half interest in three
claims. The strike was made some
weeks ago, and was reported at that
time to run 500 In gold to the ton Of
ore.
Charles Harbach on Thursday ship
ped car load of rough or block mica to
Chicago from the Florence mica mine
situated two miles east of town, owned
and operated by the Chicago Mica Com.
pany of which Mr.. Harbach is superin-
tendent. This is the first car load of
block mica ever shipped from the Black
Hills. The mica is said to be improv-
ing in quality and quantity as depth.is
attained. Six men are employed in
mining the product.
In our issue of last week we stated
that the Chilcoot group of mines, eight
miles east OF Custer was bonded to the
Big Hit Mining Company of Keystone.
In this we were mistaken, as we have
since learned that the property was this
week bonded to John Barth and John
Mates of Milwaukee, for considera-
ton Of $4,000. The bond is to run
twenty months. The owners are to re-
ceiye royalty from all ore reduced at a
profit during the running of the bond
Work is to be commenced at once.
NEW YORK MICA MINE.
The New York Mica mine, owned by
the company Of that name, and situate
about five miles west of this place, is un-
questionably ono Of the bnst rnica prop.
critics in the United States, and capable
of producing vast quantities of mica
suitable for electrical and other uses re.
quiring firmness with fexibility. This
mine has been extensively developed,
and is in good shape for economical and
systematic working, many large books
or blocks of mica can be seen all
through the open cuts, and in the shafts
and drifts, and it is safe to say that a
thousand dollars worth of mica a day
can be mined out of the 60 foot drift
alone.
Mr.. Charles A. Dow, of Sioux City,
one of the principal owners of the mine,
is now here for the purpose, as we are
informed, Of mining and shipping the
products of the mine to Chicago and
other markets where mica of the size
and quality found in the mine is in de-
mand. This is one Of the best mica
locations in the Black Hills, the ground
Is patented, and we hope very soon to
note large and continuous shipments of
mica from this property.
NEW PROCESS.
This is a description of a new pro
cess being tried in the Black Hills
The ore is pulverized to eighty or more
mesh fneness to insure a complete
lebrtaion of all the gold values, whether
they exist in the quartz or iron. The
ore is then run on grayimetric table
of special design and construction
whereby large percentage ofthe extra
neous and valueless material is removed
and the ore is reduced fifty or more
per cent. If pyritic iron exists the
ore is transferred to an automechanical
roasting machine where certain. per-
centage of the volatile matters are re-
moyed and the ore is thereby made
susceptible to magnetic influence. The
iron is then removed by powerful mag
nets. The concentrated and reduced
product carrying the values. is passed to
the chemical treating tank where the
solution is started and run for thirty
minutes. The ore Is then sampled, and
and if any values remain in it treatment
is continued thirty minutes longer.
The solution is then drawn of, the
values recovered and Immediately run
into bullion, and the tailings are wash.
ed and sent to the dump.-Pioneer.

AN ANCIENT CASE.
In recent decision, Commissioner
Hermann, of the United States Land
Office at Washington, ruled that a pat :
en-. filed ON mineral land must be carried
through without. delay. The. person
who makes the application on mineral
land must proceed with his case or he
loses all of ..is rights after reasonable Q
time has elapsed. The custom has been
to apply for patent on lands, and then,
ina great many cases, the person apply
ing has allowed the matter to rest for
years. The commissioner bases his ru'.
ing on section 1924 of the Revised Stat.
utes. The decision was given in the
hearing of case where man had ap-
piled for patent twenty-five years ago
