Rare Earth Element, Niobium, Tantalum

Property description

The Arques property is composed of one block totaling 136 claims covering an area of 61.49 km2 and a distance of some 18 kilometres in a SW-NE direction. It is contiguous to the Lemare property on its southeast border. The property is traversed in a NE direction by a Hydro-Québec power line and a permanent gravel road that heads north to the Eastmain River and beyond to the La Grande River area. Secondary roads branching off from these also provide access to the property.

The Arques project offers strong lithium potential in a well-established area. The lithium pegmatites tend to occur in swarms in the volcano-sedimentary units. The Arques property covers a large part of the regional volcano-sedimentary unit, a favourable unit that hosts Nemaska Lithium's Wabouchi deposit and the Lemarre showing.

Located in the northeastern part of the Superior geological province, and more specifically in the northeastern part of the Lac des Montagnes Formation, the Lac des Montagnes volcano-sedimentary belt is a sequence of aluminous metasediments and amphibolites containing basalts and ultramafic sills.

These rocks are highly sheared and cut by 20% late granitoids (leucogranite and biotite pegmatite).



The Lac des Montagnes volcano-sedimentary formation is running just within the South East limit of the Arques Property. The primary observed geology is mainly composed of orthogneisses formed of metamorphosed felsic intrusives.



The Arques Alkaline Complex shows similar characteristics of other deposits which are known for Rare Earth Elements (REE), Niobium (Nb) and Tantalum (Ta) mineralization.
