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. |
