Deposit type

• Banded iron formation

Summary:

The Property is located in the western margin of the Labrador Trough that extends for more than 1,000 km, from Ungava Bay to Lake Pletipi in Québec. The belt is about 100 km wide in its central part and narrows considerably to the north and south. The Grenville Front crosses the southern part of the Trough. The rocks in the Trough are subdivided into an upper volcanicdominated suite (Doublet Group) and a lower sedimentary sequence (Knob Lake Group) that
includes the Sokoman Formation hosting the iron formations found in the region.

The Sokoman formation is essentially un-deformed, strikes northwest and has a shallow dip to the northeast. The iron formation at KéMag has been explored by diamond drilling over a strike length of 9.5 km and it extends beyond the northwest and southeast Property boundaries.

The KéMag Deposit consists of magnetite Banded Iron Formation (“BIF”) of the Lake Superior
type. BIFs are sedimentary rocks composed of alternating mm- to cm-scale beds of quartz
(chert or jasper) and iron oxides (predominantly magnetite and hematite). Variable amounts of
gangue minerals, mostly silicates and carbonates, are present. BIFs have greater than 15% iron
content and have been the principal sources of iron throughout the world and host many gold
deposits (Gross, 1996).

The taconite at the KéMag Deposit consists mostly of alternating small-scale (mm to cm) bedsof recrystallized chert or jasper and massive or disseminated magnetite. Magnetite is the predominant iron oxide mineral, while hematite and martite occur in subordinate amounts. Gangue minerals are represented by iron silicates (minnesotaite and stilpnomelane), iron carbonate (siderite) and manganese carbonates (rhodochrosite and kutnahorite).
