The diamond drill. (Crystal Falls, Iron County, Mich.) 1887-1996, 1890-08-02


lied the Sheridan Mining Co.
Up to the formation of the corpo-
rate company the work had not
been carried on Systematically,
being confined to exploratory
work and open pit mining. Dur
ing the season of1Ss9, there were
/, 102 tons of ore shipped. Al
though a company had been
formed early in the winter OF 10
go, the management remained
the same, and the work of open
mining was continued until the
past spring, when the incorpo-
rators obtained the opinion of
Captain Christopher and by his
advice commenced sinking a
working shaft. After the shaft
had been carried down TO "A depth
of 105 feet a change was made in
the management, Capt. Gulgren
superceding Mr.. Sheridan. The
new captain Immediately com
menced a drift to the northward
to form the first level. This drift
was run about forty feet before
the body of ore was encountered,
and then continued across the
formation and at the present
writing is twenty feet in good
clean ore. Capt Gulgren in
speaking of the mine expresses
himself as we'll satisfied at the
outlook, and says that he has no
doubt that it will prove one of
the best mines in the district.
Owing TO the fact that SO much
preparatory work had to be done
this summer, the shipments will
not be great, but with such an
experienced miner as Capt. Gull
gren at the helm the mine will be
put in such shape the coming
winter that it will be "a big pro
Queer next year.
The probable output of theMas-
todon mine this year will be be-
tween 20, 600 and 80. 600 tons, no
ticeable gain over that of 1889.
At present mining is only being
done i'm the 800 and 350-foot lev
els. where an abundance of ore is
in sight. In about two months
work will be resumed in the open
pit; there is now a depth of $50
feet, which will be increased TO
an even depth with the bottom
workings of the mine-350 feet.
During the sinking, which is for
the purpose of cleaning up that
part of the mine, several pillars
will be removed, the whole add
ing a second working place to the
property. Some new uestle
building is going on.
The Atlas, Capt. G. t. Roberts
promising exploration. on the
southwest quarter of the south
east quarter Of section twelve,
1888, has a depth of main shaft
of one hundred feet and has
turned out some very promising
indications. The shaft will be
continued to $50 feet. but it is ex-
pected that the ore will be cut in
place before that depth is
reached, the indications for such
are the best.
The stock-p pile at the Dunn
mine has disappeared and the
dock cleaned up. A new skip
road and pocket is being built
and other preparations made to
get the ore out of the mine more
rapidly than heretofore. A great.
er part of the new machinery is
i'm place and will soon be in use.
1t is ponderous plant, built ex'
pressly for the great work ex-
pected of it.
The G.. q NV. is putting q
spur track TO the Alpha mine and
as the property is but eighty
rods, or such matter, from the
Mastodon track. the communica
ton will soon be made. The new
shaft at the east OF the property
showed the vein TO be much
stronger than in the old open pit
work.
