SnapshotThe Rose Lithium-Tantalum Project is one of the highest purity hard rock spodumene deposits with low iron and mica content.

The project is expected to produce technical and chemical grade spodumene concentrates, as well as a tantalite concentrate.

On August 11, 2022, an engineering study for a chemical plant to produce high quality lithium hydroxide monohydrate was completed by Metso Outotec and WSP in Canada. Critical Elements Lithium Corp. is not in a position to confirm whether the hydroxide chemical plant will ever be implemented or if it will form part of the Rose project.

In February 2025, the first environmental authorization required for the construction and implementation of the Rose project was received. Corporation expects to be in a position to commence the activities subject to this authorization once all the conditions mentioned in the Federal and Provincial Project approvals have been met, the required Project financing has been obtained and FID is made.

Deposit type

  • Pegmatite

Summary:

The Rose property is located in the southern portion of the Middle and Lower Eastmain Greenstone Belt.

The Middle and Lower Eastmain Greenstone Belt (MLEGB) contains more than one hundred mineral showings exhibiting a variety of ages, host rocks, styles (disseminated sulphides, massive sulphides, veins and dykes) and metal suites. The mineral occurrences of the MLEGB have been divided into six (6) types according to Moukhsil et al. (2007):
1) Sulphide facies iron formation.
2) Volcanogenic mineralization.
3) Magma-related mineralization.
4) Orogenic mineralization.
5) Gold-bearing mineralization associated with oxide- or silicate-facies iron formations.
6) Pegmatite-related mineralization.

Types 1 to 3 are associated with an episode of volcanic arc construction (volcanic cycles 1 to 4). Types 4 and 5 are contemporaneous with major deformation events (D1 and D2), whereas Type 6 is associated with post-tectonic intrusions.

Based solely on its geological environment, the Rose property has potential for a number of deposit types. However, based on the known discoveries, only the type recognized in Type 6 (Rare-Element LCT-type Pegmatite) will be discussed herein.

Gabbros, pyroxenites and diorites cut across the property geology. The Pivert-Rose property also hosts pegmatites, occurring as irregular but generally continuous lenses within the biotite schists.

Other rock types, including gneiss, dacite, quartzite and conglomerate, have also been reported. Lithologies are generally well foliated with a SE orientation, except for the more massive and unfoliated granites and pegmatites.

Mineralization recognized to date on the Rose property includes rare-element LCT-type pegmatites (Block A) and molybdenum occurrences (Block A). An iron occurrence (Block B) is also mentioned in the government database.
