The diamond drill. (Crystal Falls, Iron County, Mich.) 1887-1996, 1890-09-20


There yet remains strip Of sur
face half the length of the pit and
perhaps four or five feet deep TO
be removed. This ground is
very hard. requiring powder in
removing it; but Ehe work once
done there will ~ aim immense
body of ore N nd dfred, which
can be easily and cheaply mined.
In No. shaft at a depth of 100
feet a cross-cut has been com
menced-in north eight feet,
south seven feet and will be con-
tinued the width of the vein. In
this shaft is shown q body of
manganese ore-about thirty per
cent. manganese and q like per
centage of metallic iron. The
manganese has always been a
telling feature Of the ore in an
adjoining property, but never
going over four or five per cent.
AS the newly discovered body
OF ore in No. / is penetrated
il gives q marked increase in the
percentage of manganese. Should
the depth prove to hold any
great quantity of that character
of ore it will lift the Manganate
far above any of the range mines
in value. So soon as the cross
cut is finished the shaft will be
lowered seventy-five feet for a
second level. Some hosting is
going on from No. 2 shaft. The
mine is fixing for a huge output
next year.
Edwin Ball this week resigned
the SUPPLEMENTARY Of the Mans
field mine, and will return to
Florence next week His work
at the mine will be carried on by
John Erickson and Capt Louis
Ashleman.
