Steadright Critical Minerals Inc. to Acquire up to 75% Interest in the Péribonka Ree-Niobium Carbonatite Project, Saguenay-Lac-St-Jean Region, Québec

(TheNewswire)

Muskoka, Ontario – TheNewswire - September 11 th , 2026 - Steadright Critical Minerals Inc. (CSE: SCM ) (“Steadright” or “SCM”) is pleased to announce that it has entered into a definitive Option Agreement to acquire up to a 75% interest in the Péribonka Rare Earth Element (REE) and Niobium Carbonatite Project , located in the Saguenay–Lac‑Saint‑Jean Region of Québec, Canada.

The Property represents a low‑cost exploration opportunity for critical minerals, strategically positioned within a proven alkaline intrusive district that hosts Canada’s only producing niobium mine.

Péribonka REE–Niobium Carbonatite Project Overview

The Péribonka Project covers a distinct ovoid magnetic anomaly interpreted to represent a carbonatite or alkaline intrusive body comparable to nearby niobium‑ and tantalum‑bearing systems associated with the Saguenay Graben.

Key Geological Features

Characteristic ovoid magnetic anomaly with deep roots and a surrounding magnetic negative ring.

Covered by thin alluvial sand deposits , with bedrock estimated at 30–60 metres depth

Anomalous trace Rare Earth Element values at surface in historical government datasets (GM40582).

100% ownership of 37 contiguous claims , with expansion potential.

Road‑accessible , no helicopter support required.

Located a few kilometres north of St‑Ludger‑de‑Milot , with nearby powerlines, roads, and port access.

Regional Context: Saguenay Graben Alkaline Intrusions

The Property lies within a major structural corridor hosting multiple alkaline and carbonatite intrusions, including:

Niobec Mine (St‑Honoré) — operating since 1976, the only niobium mine outside Brazil.

Crevier Nb‑Ta nepheline syenite dyke , extending over 3 km (SGS Technical Report, 2010).

Shipshaw and Falardeau carbonatites , discovered between 2010–2013.

The Péribonka anomaly exhibits similar geophysical characteristics to these known intrusions and remains completely untested by drilling due to overlying sand and gravel.
