The mining reporter of The
DIAMOND DRILL visited the
Mansfield mine early this week,
and, thanks TO the affable and
accommodating local officers, is
able to give a pretty clear under
standing Of what is being done
at the splendid property. All
active mining work is being con
fined TO the third and fourth lev
els at present, though the second
IS by no means out Of date. On
this level the length of the vein
has been shown $50 feet and has
not given out. OF this distance.
o32 feet is TO the south, the vein
having an average width Of thir-
" feet and the ore holds up to
the standard Of excellency char
acterjstic of the mines product.
The s6uth end of the property
will be taken in hand as soon as
arrangements can be made, and
extensive exploratory measures
adopted, which is sure TO result
in the sinking of a shaft at that
part of the mine. 1t has been
shown beyond a doubt that the
vein does not cross the river al
that point, but continues 10 the
end of the Mansfeld's leased
ground and will be found on the
forty adjoining. under option TO
Messrs. Smith 81 Ray, of Mil
waukee. The daily output OF
the third level is about $50 tons,
while 100 tons are daily removed
TO surface from the fourth le vel.
Mining in the fourth is fully es.
tablished and is going along in
q manner most satisfactory to
the management. The openings
now measure ninety feet TO the
north of the shaft and one hun
dred feet TO the south. both be
ing the width of the vein. TAX.
en- as q whole the mine is in the
best possible shape for the time
OF the year and has ore i'm sight
estimated at 100000 tons. The
shipment per day is about 25O
tons TO the Illinois Steel Com
pany's Union Works, at Chicago.
The contract with this concern
will end with the present month
or thereabouts, and no more ore
is likely to be sold for a time; but
as soon as the existing contract
expires stocking will be inaugur-
ated and goodly block of ore
piled up to commence the '9s
shipments with. Not long ago,
Supt. Calhoun discovered ore OF
a very high quality in the bed OF
the Michigamme river, a short
distance above the mine, and now
preparations for learning all
about ii are in progress. "A
shaft 1x5 feet inside is going
down at a point near where a di
amond drill hole was put down
last summer, about 400 feet north
of No. 4 shaft. The new shaft
will go down 80 feet and a cross
cut carried east under the river,
which will undoubtedly show the
value of the outcropping. Should
IL prove of worth, the shaft viii
