Announcement PDF Level 8, 2 Bligh Street Sydney NSW 2000 Mont Royal Resources Ltd ACN: 625 237 658 E: info@montroyalres.com www.montroyalres.com ASX ANNOUNCEMENT 5th May 2026 Ashram Project Fluorspar Development Update Significant tenor of contained Fluorspar within the anticipated open pit underpins ongoing Fluorspar metallurgical test work program at Ashram MONTRÉAL,Quebec– May 5th ,2026 – MontRoyal ResourcesLtd (ASX:MRZ, TSXV: MRZL) (“Mont Royal” or “the Company”) is pleased to provide an update on the significant fluorspar potential contained within the principal area of the MRE targeted for the impending PEA for its Ashram Rare Earth and Fluorspar Project in Quebec, Canada. The Company sees a significant opportunity for fluorspar as a byproduct through continued development of the Ashram Deposit. HIGHLIGHTS • Globally significant Fluorspar endowment within the current Mineral Resource Estimate1 . • One of the largest known reported resources on the ASX & TSX.V with 73.2 Mt contained CaF2 at 6.6% in Indicated Mineral Resources, and an additional 131.1 Mt CaF2 at 4.0% of Inferred Mineral Resources. • Historical metallurgical test work (Hazen, 2020) delivered a 98% CaF2 (acid-spar) concentrate. • Fluorspar recently named as a critical mineral in Canada, the United-States, and Europe. • Near-term focus on additional fluorspar test work to support the addition of a fluorspar circuit in the upcoming Pre-Feasibility Study. • Rapidly evolving market dynamics for fluorspar, with China shifting to being a net importer of the critical mineral, driven by surging industrial and downstream demand. 2 Mont Royal’s Managing Director, Nicholas Holthouse, said: “Metallurgical test work completed in 2020 has already demonstrated the potential for the contained fluorspar from the Ashram Deposit to be successfully upgraded to a saleable fluorspar concentrate product. “With 73.2 Mt contained CaF2 at 6.6% in the Indicated category of the MRE, and additional potential from 131.1 Mt at 4.0% CaF2 in the Inferred category at Ashram, along with reliable grade consistency within the resource domains we see a compelling opportunity to develop a valuable secondary revenue stream for the Project, alongside and complimenting rare earth production. “In recent months, capital markets have woken-up to fluorspar, with market dynamics strengthening considerably, supported by its growing importance across high- technology, medical, and industrial applications. The Ashram Project has the potential to become a major fluorspar supplier to North America and European industries, with Quebec’s aluminium industries alone consuming around 150-200kt of CaF2 per annum. “Despite being the world's largest producer, China has recently become a net importer of fluorspar, particularly for high-purity HF acid used in semiconductors. Thishas created a structural squeeze on ex-China inventories, which bodes well for future fluorite prices and for ex-China developers like Mont Royal.” Figure 1 Previously produced 98% Fluorspar concentrate from Ashram Deposit. 3 Historical Fluorspar Grades and Mineral Resource Estimates The Ashram Project hosts a consolidated NI 43-101 Mineral Resource Estimate1 (MRE) of: • 73.2Mt @ 1.89% Total Rare Earth Oxide (TREO)2 and 6.6% Fluorspar (CaF₂)3 Indicated, and • 131.1Mt @ 1.91% TREO & 4.0% CaF₂ Inferred.

Mineral resources are not mineral reserves as they do not have demonstrated economic viability. 2 TREO = sum of all lanthanide oxides + yttrium oxide 3CaF2 calculated from fluorine assay using factor of 2.055 (F to CaF2). Assumes all fluorine is contained within the mineral fluorite. Previously completed test work In 2020, Commerce Resources focused on upgrading the Ashram Deposit’s fluorspar component to acid-spar grade (refer to the announcement dated February 28, 2020 – Commerce Resources Corp. (TSX-V: CCE, FSE: D7H)). 4 The test work, which was carried out by Hazen Research, CO, USA, resulted in the successful upgrade of the fluorspar content of the Ashram Deposit to a purity of 97.8% CaF₂, which exceeds the 97% base criteria that is typical of acid-spar grade. This high-grade test result demonstrated the applicability of standard physical separation techniques to upgrade the Ashram Deposit’s fluorspar component from a head grade of ~7.5% CaF₂ to grades exceeding 97% CaF₂, which would be required to achieve an acid-spar grade product. The processing approach utilizes a relatively coarse grind followed by a fluorspar pre- float as an initial upgrade step to isolate a sizeable portion of the fluorspar prior to material enteringthe primaryrare earth element (“REE”)recoveryflowsheet.Thefluorspar flotation concentrate was then processed by magnetic separation, resulting in the desiredCaF₂grade,whilethereject fractionsaresentback to the primaryflowsheetcircuit where the REE component is then recovered along with the bulk of the REEs.

Fluorspar Markets and Pricing Fluorspar prices remain robust moving into 2026, supported by strong end-market demand from the chemical, metallurgical and energy-transition sectors, together with tightening global supply. Fluorspar pricing is considered on a Cost, Insurance and Freight (CIF) basis into Atlantic Basin consuming markets, consistent with delivery into Eastern North America and Western Europe, which are relevant to Québec-based export routes via Sept-Îles and the Port of Saguenay. Current benchmark fluorspar pricing remains typically in the range of US$500 to US$650 per tonne, dependent on product grade, specification, delivery point and contract terms. 6 This pricing reflects prevailing bulk shipping rates, marine insurance and port handling costs associated with trans-Atlantic and coastal North American freight. Acid-spar fluorspar (>97% CaF₂), which accounts for approximately two-thirds of global fluorspar consumption, is the highest-value product category. CIF pricing is currently reported in the range of US$540 to US$680 per tonne, reflecting the ongoing sustained demand for hydrofluoric acid (HF) and downstream fluorochemicals used in pharmaceuticals, aluminum production, semi-conductors and lithium-ion battery materials. Acid-spar is a consumable and non-recyclable raw material, requiring continuous primary mine supply to satisfy global demand growth. Met-spar fluorspar (>60% CaF₂) accounts for roughly one-third of global fluorspar demandand ismainlyusedasa fluxin steelmakingandcementproduction.Currentmet- spar prices are typically US$420–US$520 per tonne, supported by steel and aluminium output and limited substitution in metallurgical and cement applications. Quebec’s aluminium industry alone consumes about 150–200 kt of CaF2 equivalent each year. Japan is also a major consumer, importing about 450–500 kt of CaF2 per year. Demand is driven by end uses such as semiconductors, batteries, refrigerants, fluoropolymers, and other advanced materials. China was historically the dominant fluorspar exporter but has recently shifted to being a net importer, driven by domestic mine closures, tighter environmental regulation, and risingdownstreamdemand.Thischangehastightenedglobal supply–demandbalances and supported prices, increasing consumer interest in securing long-term supply from geopolitically stable Atlantic Basin jurisdictions, including Canada.
