Dec 07, 2005 (A Wilson) - The South Evans Creek iron range extends from the axial planar fault along Evans Creek. this fault separates the South Evans Creek iron range from the north end of the Godon Lake Iron Range. The iron range is continuous from Evans Creek to just beyond the east boundary of Leclaire Twp. It is separated from the North Evans Creek iron range by a strike slip fault along Evans Creek. A short segment of this iron formation in the vicinity of Pashoskoota Lake has been termed the Finger Lake Iron Range. Unlike the North Evans Creek iron range, this iron range is considered to be a Michipicoten-type iron formation.

Dec 07, 2005 (A Wilson) - The iron formation is commonly brecciated and in outcrop consists of iron stained laminated chert. Collins et al. reported an irregular band of pyritic material on the east side of the range which is locally associated with siderite and granular silica. On the north side, the iron formation is in contact with schistose to massive intermediate to mafic metavolcanic rocks. Ont he south side, the iron formation is in contact with intermediate to felsic tuffs, sericite schists, feldspar crystal tuffs and breccia.
