KEY ASSETS AND STRATEGY The merged Company’s flagship asset is the 100%-owned Ashram Rare Earths & Fluorspar Project (“Ashram Project”), which represents the largest undeveloped monazite-mineralised carbonatite-hosted Rare Earth Elements deposits in North America. In addition, the Company also holds the Eldor Niobium Project and the Northern Lights Lithium Project, both also located in Québec (see Figure 1 below). The Ashram Project is a Tier-1 REE deposit with high-value by-product potential (Fluorspar) and represents one of the most advanced rare earth development projects in North America. With over A$50 million invested historically in exploration, drilling, resource definition and development studies, Ashram represents a cornerstone asset in Canada’s critical minerals push. Figure 1: Ashram REE & Fluorspar Project Location and location of Northern Lights Project. The Ashram Project contains a Mineral Resource Estimate (“MRE”) as at 4 April 2024: o Indicated: 73.2Mt @ 1.89% Total Rare Earth Oxide (TREO) & 6.6% Fluorspar (CaF₂) o Inferred: 131.1Mt @ 1.91% TREO & 4.0% CaF₂ A cut-off of C$287/tonne is considered as the base case for the MRE and is guided by reasonable prospects of eventual economic extraction over a reasonable timeframe. The cut-off grade considers a CAD:USD exchange rate of 1.30. Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. The MRE was reported in Mont Royal’s replacement prospectus dated 30 September 2025 (“Replacement Prospectus”). The Company confirms that it is not aware of any new information or data that materially affects the MRE and that all material assumptions and technical parameters underpinning the MRE continue to apply and have not materially changed. The Ashram deposit has a high distribution of Neodymium and Praseodymium (NdPr)/TREO of ~21.1% (Indicated) and 21.4% (Inferred) – key rare earth elements that are essential for permanent magnet 3441-8565-6896v25 ASX: MRZ production. The project has excellent mineralogy, with simple flotation producing a +35% TREO concentrate with 65% recovery. Hydrometallurgical recoveries of 95% have been achieved for light rare earth elements (“LREEs”) and 82% for heavy rare earth elements (“HREEs”), delivering a clean, marketable mixed rare earth carbonate (“MREC”). Mont Royal is advancing a staged, lower-risk development plan for the Ashram Project: 1. Stage 1: Focus on mining, beneficiation and production of a high-grade flotation concentrate. 2. Stage 2+: Potential downstream development in hydrometallurgy, oxide separation and collaboration with industry partners to produce separated oxides, metals and magnets. An updated Preliminary Economic Assessment (“PEA”) is underway to guide development, support government funding applications, and advance strategic partnerships and offtake discussions. The Ashram Project also offers valuable by-product potential via a potential by-product fluorspar stream (metallurgical and acid grade) to supply North American markets. Fluorspar is a highly strategic mineral used in the production of steel, enriched uranium, aluminium and petroleum-based fuels. CAPITAL RAISING & TSX-V LISTING Mont Royal lodged a replacement Prospectus with ASIC on 30 September 2025 with respect to an offer to raise A$8 million and up to A$10 million (before costs) by the issue of between 40.0 million and no more than 50.0 million new fully paid ordinary shares on a post-consolidation basis at an issue price of A$0.20 per share.
