Jabez Williams staked claims over the iron deposits of Lake St. Joseph in the early 1900s. Consolidated Mining Company of Canada Ltd. completed beneficiation studies in July 1932; they concluded that gravity separation would be preferable to flotation. Lake St. Joseph Iron Ltd. drilled the iron deposits from 1957 to 1959 and contracted Laurier Juteau to compile reserve estimates in 1960/61. Hanna Mining and later Algoma Steel Corp Ltd. conducted property appraisals from 1961 until 1976; they concluded that the property be rejected 'because of complicated metallurgy'.

Aug 27, 2007 (Mark Puumala) - The banded iron formation of Western Lake St. Joseph is hosted within metasedimentary rocks of the Eagle Island Assemblage. Shlanka (1968) indicates that this iron formation extends for an east-west strike length of approximately 10.5 km, and that it attains widths of up to 152 m. The iron formation is described by Clifford (1969) as consisting of alternating laminae of magnetite-rich and quartz-rich material. The iron formation is also reported to contain lesser amounts of biotite, chlorite, epidote, hematite and carbonate. At the far western end of the iron formation, where the metamorphic grade is highest, amphibole and garnet have also been noted. Clifford (1969) indicates that the iron formation has been intensely folded, with one major synclinal structure having been identified. The closure of the main syncline is located along the eastern shore of Eagle Island (see ODM Map 2159), with the northern and southern limbs of the structure forming the northern and southern shorelines of the island (i.e., the axial plane generally strikes east-west). The two limbs of this structure have been mapped to the west across Fish Island, Wolf Island and Island 184.
