High-Grade Fluorspar Identified at the Ashram Project's Mallard Prospect

About this update from Mont Royal Resources Ltd.

Significant grades of contained fluorspar of up to 39.8% CaF2 within the previous niobium drill holes at Mallard Prospect Montreal, Quebec--(Newsfile Corp. - May 26, 2026) - Mont Royal Resources Ltd (ASX: MRZ) (TSXV: MRZL) ("Mont Royal" or "the Company") is pleased to provide an update on the significant fluorspar (CaF2) potential contained within previous drilling results at the Mallard Prospect, located approximately 1.4km south-east of the Ashram Deposit within the Eldor Carbonatite Complex in Québec, Canada.

"This separate mineralised system, with contained CaF2 grades of up to 39.8%, is located less than 2km south-east of the Ashram Deposit. Importantly, previous drilling campaigns at Mallard primarily targeted niobium, highlighting the significant potential for future fluorspar upside through targeted drilling. "With fluorspar rapidly emerging as a strategically important critical mineral and market dynamics continuing to tighten, we believe that Ashram and the broader Eldor Property are increasingly well positioned with the Flux Zone presenting additional fluorspar mineralisation upside and an opportunity for potential future co-development in proximity to the Ashram Deposit." Previously Completed DrillingThe fluorspar (i.e. fluorite) mineralized zone at Mallard, now referred to as the "Flux" Fluorite Zone, was discovered in previous drilling (2008) and is located approximately 1.4 km to the south-east of the Ashram Deposit (Figures 1 - 3; see 2018 NI 43-101 Technical Report). Although not specifically targeted by historical drilling which focused on niobium potential, the zone was expanded along strike during 2010 and 2024. The zone, as interpreted to date, has approximate dimensions of >80m along strik...
