Deposit type

  • Banded iron formation


The Rainy Lake property is located on the extreme western margin of the Labrador Trough adjacent to Archean basement gneisses. The Labrador Trough is a sequence of Proterozoic sedimentary rocks, which includes the Sokoman Formation within the Knob Lake Group. The Sokoman Formation is an iron formation consisting of a continuous stratigraphic unit that thickens and thins throughout the Labrador Trough.

The thickness of the Sokoman Formation varies between 120 and 240 meters and is a typical Lake Superior type iron-formation (taconite) consisting of banded sedimentary rock composed principally of layers of iron oxide, magnetite and hematite. Iron-rich bands are intercalated with cherty bands composed of variable amounts of silicate, carbonate, sulphide, ferruginous slaty iron formation, and carbonaceous shale. The Sokoman Formation is subdivided into eight stratigraphic subunits: Lean Chert ("LC"), Jasper Upper Iron Formation ("JUIF"), Green Chert ("GC"), Upper Red Chert ("URC"), Pink Grey Chert ("PGC"), Lower Red Chert ("LRC"), Lower Red Green Cherty ("LRGC"), and Lower Iron Formation ("LIF").

On the Rainy Lake property the Sokoman Formation is thickened by shallow east dipping northwestsoutheast thrust faults and is gently folded resulting in unusual thickness of iron mineralization reaching 400 meters locally. The area investigated by drilling was named the Full Moon iron deposit.
