Point Location Description: open pit
Location Method: Data Compilation
Access Description: The site is accessible, by prior arrangement with Algoma Steel Corp., via the G. W. Macleod mine access road from the town of Wawa. The open pit is located approximately 3.5 km NE of the former government dock on Wawa Lake.

Jan 08, 2016 (A Wilson) - The Helen Iron Range marks the upper sequence or capping of the second cycle of volcanism in the Michipicoten Greenstone belt. It represents the chemical and clastic sedimentation separating the volcanic cycles. This iron formation forms a distinctive marker horizon throughout the greenstone belt and has been extensively thickened because of drag folding associated with the Talbot Lake Fault. The East ore body is separated from the West ore body by a diabase dike.

Jan 08, 2016 (A Wilson) - The carbonate (siderite) phase lies at the base of the Michipicoten iron range and is dominated by siderite. The carbonate unit lies in sharp contact with the underlying felsic fragmental rocks. At the Helen Iron Range, a chert horizon lies between the siderite and the footwall volcanic rocks which varies from 1 - 10 m in width. The carbonate facies also hosts an internal coarse-grained structureless chert unit which ranges from 0 - 20 m in width this zone is also known as the 'D' Zone. The stratigraphic section is monoclinal, faces north and dips approximately 80 degrees to the south. The section is overturned and the mining hangingwall is the stratigraphic footwall.

Jan 08, 2016 (A Wilson) - The average compositiion of the east ore body was approximately: 33.73% Fe, 10.4% Si and 2.03% S. The iron is lower and the silica higher on the average than in the West ore body. The siderite is dense and massive.
