Province: Superior
Geological Age: Early Precambrian
Sep 30, 2014 (Therese Pettigrew) - The banded quartz-magnetite iron formation of the Algoma type, oxide facies, is located within the north part of a band of metasediments some 12 miles wide. About 2 miles north of the iron formation, the metasediments are cut off by a large granitic intrusion. The metasediments consist for the most part of biotite schists and gneisses. All the rock types are Early Precambrian in age and are located within the Superior structural province. The iron formation strikes E-W for about 4.5 miles bu the main zone is 2400 ft long and located in the eastern part of the iron formation. IN the main zone, the iron formation consists of lenses 60-120 ft in width of massive to coarse-grained magnetite grading 31 to 33% Fe. The main zone strikes N75°E. The overburden on the property is extensive with no outcrop exposure.
