HOPPER REPORTS ON
I ''VANADIUMS MINE.

per OF tne michigan Cohege OF mines
discounts the theory that rich vanadi-
um beds are in Aryon township, Bara-
ga county. II was reported several
months ago that such beds were there.
When the story was first announced
State Geolopist Allen was very skeptic-
al. As a result. he sent Prof. Hopper
to investigate the mines. To fully In
form possible investors. Mr.. Allen gave
out Prof. Hopper's report this week.
After describing the location and
work already done, Prof. Hopper says:
Upon examination the specimens
taken from one wall of the shaft ap-
pear to be q green schist. The speci-
mems from the other wall appear to be
medium grained gray colored aplite
or granite. The specimens taken from
the middle of the supposed vein. are
green schist similar to the one wall
rock. Several specimens Of . lighter
colored aplite. or granite, and coars-
er pegmatite were found on the sur
face few feet from the shaft.
''The several specimens taken from
the dump show principally quartz, ga
lena, and very little pyrite and chal-
copyrite. One specimen shows the
green schist cut by the aplitic rock in
contact with mass Of vein quartz car
rying galena and calcite. A second
specimen shows = mass Of vein quartz
m inch and . quarter in width with
sehist on one side and aplite on the 9TH
er side. A third specimen shows wall
Of green schist and . mass Of vein
quartz about three inches wide carry
ing considerable galena. Another large
specimen appears to be breccis COM
posed Of green schist, vein quartz, cal-
cite, probably dolomite, and perhaps
ciderite. The rock il stained in places
with iron oxides.
From the specimens examined the
local geological history is believed to
be a. follows:
Green schist intruded by granite
and dikes Of aplite. Fracturing and
brecciation. Filling Of the fractures
and breccias with carbonates and
quartz carrying galena and small
amounts Of pyrite and chalcopyrite.
The veins are from one to three or
four inches in width. Replacement Of
the dikes and breccias has also taken
place.
THE prospect pit on the south hill,
or the so-called Mohatin Hills mine,
was also examined. The geological
conditions appeared to be practically
the same as at the Bug Hole mine.
mo evidence Of the presence Of the
reported minerals endlichits or carno-
tite can be found in the specimens ex-
aminod. There are numerous red and
brownish-yellow spots which appear to
be iron oxide.
''Ths mining property. consisting Of
the s. w. quarter of Section 36, Town
ship 50, Range 30. 160 acres, ID owned
by John Thompson Of Chicago. Mr..
Thompson acquired the property some
thirty years ago from . homestsader,
who. at the time he rslinquished own
ership, told Mr.. Thompson that the
property was valuable ~ mineral land.
Numerous people including several 'ex-
perts' hsve examined the property at
various times during the last ten years.
The land has always been considered
iron bearing.
During the summer Of 1914 par
ty In Chicago secured an option on the
property but allowed the option to ex-
pire. Late in the summer George
McGhee, while examining samples in
Chicago discovered vanadium and
uranium minerals in the specimens. Mr..
McGhee later visited the property and
wrote the report which was published
insthe Mining and Engineering World.

Comments on Mr.. George w. Nc
Ghee's article on the svanadium Dis
covery in Baraga County. Michigan
''The mining property Is not seven
miles north Of Shanes but about nine
miles east and south Of Skanee. The
'prospscts are not located on John Nc
Combs farm but about three miles
southeast Of Mr.. McComb's property.
''Mr. McGhee states that the crop
pings on these hills are very extensive
and show the mineral Qead vanadate)
