Dominion mine, Madoc, Huntingdon Township, Hastings Co., Ontario, Canada

Ref: GSC Paper 69-50, Ann P. Sabina (1970), Pg. 132.

In trap rock, slate and altered crystalline limestone.

"Magnetite occurs as bands, as disseminated grains and as veinlets in the rock. Epidote is common as granular streaks associated with calcite and pyrite. Hematite and martite have formed from the magnetite and occur sparingly. Smaltite has been reported to occur in magnetite and erythrite as a coating on the magnetite.

The deposit was worked for iron many years ago from an open-cut measuring 125 feet by 18 feet. The opening was made into the side of a wooded ridge."
