The CLC Iron Deposit is located in Labrador, Canada, 55 kilometres southeast of Schefferville, Quebec and 200 kilometres north of Labrador City. The Deposit is hosted within the 6 square-kilometre CLC Property (100% owned by Anteros Metals Inc) in rocks of the iron-rich Sokomon Formation, approximately 3 kilometres along strike from the Labrador Iron Mines Sawyer Lake Iron Deposit.
The Labrador Trough is a Proterozoic orogenic iron belt that extends from the eastern margin of Ungava Bay southwards to Labrador City and has been mined for iron ore since 1954. The principal iron formation unit of the area, responsible for world-class iron-ore deposits, is the sedimentary subaqueous Sokoman Formation of the Knob Lake Group, a 30 to 350 metre continuous stratigraphic unit along the length of the Labrador Trough. Deposition of the Sokoman Formation resulted from oxidation of upwelling waters rich in reduced iron in conjunction with continual transport of the iron towards a shallow-water, oxidizing environment of the sedimentary platform.
The Sokoman Formations and the Wishart Formation (stratigraphically below the Sokoman) are intruded by a number of gabbro sills and dikes, which may be related to Nimish volcanism.
The Sokomon Formation is tightly-folded in broad anticlines and synclines of the Petitsikapau Lake Synclinorium in the area of the CLC Property. Fold hinges may have resulted in thickening of iron-rich horizons of the Sokomon Formation such that the width of the iron-bearing horizon on the Property is over 150 metres in true thickness.
The CLC Deposit is located along strike from the Sawyer Lake deposit in the same package of rocks. Recent exploration and drilling by Mamba Minerals Ltd focused on drill targets identified by magnetic and ground gravity surveys, the largest of which underlies the CLC Deposit. In total, altered and enriched iron formations were encountered in Mamba Minerals drillholes along a total strike length of more than four kilometres. The altered iron formation has a true width in excess of 150 metres, with grades of 52% Fe over 101 metres in DDH MM-13-05 and a number of high-grade intervals of greater than 60% Fe.
