An iron mine owned by Dofasco. Operated from 1967 until 1990; it had a 1.1 million tons/year capacity.

An Archaen Algoma Fe type deposit that consisted of banded iron formation (BIF).
The Sherman Mine was owned and operated by Dofassco/Cliffs of Canada from 1968-1990.
The deposits are within the bands of Keewatin iron formation thought to be within the archean "Abitibi Greenstone Belt" with an approximate age of 2.2 billion years.The iron formations are a total of 76 meters wide and 600 meters strike length. The bands are composed of well banded light to dark grey magnetite and dark green meta-chert with local red jaspillitic bands. The pyritic nodules were noted in graphite beds associated with the iron formation.
The mine name was derived from a well known pioneer of the Canadian steel industry Frank Albert Sherman(1887-1967)
