Meråker Geology and Mineralization

The Meråker property is aligned in such a way as to cover two separate mineralized trends: one within the Kjølhaug Group and a second within the Fondsjø Group. As such, the majority of property is underlain by the two groups, along with the intervening Sulåmo Group.

The overall dip of stratigraphy is towards the west-northwest; thus the eastern and southern portions of the property are structurally lowest, and are underlain by sandstone, slate, conglomerate and greywacke of the Kjølhaug Group. Sedimentary layering is visible and generally banded on a cm to dm scale, with alternating greywacke and schist bands common throughout the area. Carbonate cement is present but rare in the greywacke units. Extensive gabbro sills are also present, generally with a strike parallel to host stratigraphy. The contact of this unit with the structurally overlying Sulåmo Group is interpreted to be tectonic. The Gilså, Lillefjell, and Anna-Ebba-Duddu showings are located within this horizon, at roughly the same stratigraphic level ~ 1 km east of the contact with the overlying Sulåmo Group.

The southwestern and central parts of the property are underlain by the Sulåmo Group, dominated by slate, sandstone, mica schist and conglomerate with minor basalt. Recorded mineralization is much sparser within this group, with only a handful of historical showings. The only significant results from modern sampling within this group are from showings in a basaltic horizon near the contact with the Kjølhaug Group. This horizon has been termed the Turifoss Greenstone by previous workers, and can be traced for 20 km of strike length (8 km of which lie within the property) with a thickness of ~1 km. It is this unit which is in tectonic contact with the Kjølhaug Group. The western edge of the Sulåmo Group is defined by a 10 m thick conglomerate unit, interpreted be a basal conglomerate and taken as evidence for the overturned nature of the stratigraphy in the area.

The northwestern portion of the property is underlain by the Fondsjø Group, composed of basalt, co-magmatic dykes and gabbro (simply termed “greenstone” in much of the historic mapping) intruded by tonalitic rocks. Structurally overlying this sequence is a series of felsic volcanic rocks, which are in turn overlain by tuffaceous sediments with interlayered pillow basalt and felsic pyroclastic rocks. A string of historic showings is present at the same stratigraphic level as the felsic volcanic rocks, with the most significant being Mannfjell and Fonnfjell.
