Dec 07, 2005 (A Wilson) - The Johnson Iron Range is one of the 32 separate iron ranges that form the Michipicoten Iron Formation. The Johnson is the eastern extension of the Eleanor Iron Range and describes that section of the iron formation that lies between the Wallbank Lake Fault to the west and the western branch of the Mildred Lake Fault to the east.

Dec 07, 2005 (A Wilson) - The iron formation faces north and dips vertically to steeply south. It separates intermediate to felsic metavolcanic rocks at the top of cycle one from intermediate to mafic metavolcanic rocks of cycle two. Brecciation of the unit suggests that shearing or faulting has occurred parallel to the bedding. The iron formation is believed to consist of a lens of about 65 feet of siderite on the south side, succeeded by a 65 foot wide zone of banded silica on the north side.
