The M3ehigan mine in Ontonagon county broke
Its best previous record BY turning out 1877
tons OF mineral last month. Including the heavy
eopper.that is. the mass and barrel work-the
production was secured from the treatment
Of slightly less than 500 tons Of rock daily.
While the Michigan cannot increase its pro-
Its rock at the Mass Consolidated company's
mill, 1t will soon be able to enlarge its rock
shipments as arrangements have been made for
the use Of two heads in the Atlantic mill The
Michisan's lease of the head it is now using
at the Mass mill expires shortly, but, as the
Atlantic is not producing at present, It leased
two Of Its stamps to the Michigan. AS soon
as the rock shipments are transferred to the
Atlantic plant an increase Of more than 100
tons day in the rock output will be possible.
Additional machinery is being taken to the
scene Of the Keweenaw Copper company's actiy-
tiles in KeweenaW county. boiler plant
hoisting engine and twelve-drill air compressor
are being installed at the Medora shaft The
company is continuing Its diamond drill ex-
ploratory work. s'. zs 4.-l1- 3,
At the Erie Ontario. Development company's
property, few miles south Of the Champion
mine, some favorable copper ground has been
encountered in drift which is being driven
northward on the lode at the 150-foot level OF
the shaft. While the lode does not contain the
metal In commercial quantities at that point
the outlook is considered very favorable by
the management, 1t is far better than any
thing encountered for some time. Drifting is
also under way on the lode to the southward
At both points the rock Is softer and Of 4
more healthy character than penetrated in the
openings nearer surface.
Sinking in No. 1 shaft Of the Centennial mine
has been resumed The Centennial engineering
staff has recently completed a survey Of the
entire mine and the figures show over ], 900 600
tons Of lode rock blocked out in the property.
