The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration. Iron formation is believed to be of sedimentary origin. In Ontario three epochs of deposition are known: 1. (a) Keewatin-Grenville, as in the Michipicoten and.
