Geological ages: Neoproterozoic (host rocks)
Tectonic setting: continental margin
Host rocks: (1) sedimentary; mudstone-sandstone-conglomerate (banded hematitic and jasper iron formation)
Individual lithologies:chert-hematite (banded)

Qualified comments: (Applies to: location ) Exposed over a huge area in the Keele watershed, and may extend into Northwest territories.

(Applies to: reserve/resource descriptions) Historical mineable reserves are over 3 billion metric tons grading 43.8% Fe, 26.6% SiO2 and 0.34% P. Geological mapping suggests that the deposit is much larger, with a regional reserve estimated to exceed 18.6 billion metric tonnes.
