Updated Preliminary Economic Analysis Confirms
Ashram as a Major Long-Life North American Rare
Earths Development Project
ROBUST UPDATED PEA HIGHLIGHTS ASHRAM’S POTENTIAL TO BECOME A
STRATEGICALLY IMPORTANT LONG-TERM SUPPLIER OF RARE EARTHS INTO
WESTERN CRITICAL MINERALS SUPPLY CHAINS
Cautionary Statement
The Preliminary Economic Assessment (PEA) is a preliminary technical and economic study of the potential
viability of the Ashram Rare Earths & Fluorspar Project. It is based on low-level technical and economic
assessments that are not sufficient to support the estimation of Ore Reserves or to provide assurance of an
economic development case at this stage, or to provide certainty that the conclusions of the PEA will be
realised. Further exploration, technical, and economic studies are required before the Company will be in a
position to estimate any Ore Reserves or to provide assurance of an economic development case. The PEA
has been completed to a level of accuracy of ± 50%.
Forward-Looking Statements
The PEA is based on the material assumptions outlined in this announcement. These include assumptions
about the availability of funding. While Mont Royal considers all of the material assumptions to be based on
reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes
indicated by the PEA will be achieved.
To achieve the range of outcomes indicated in the PEA, funding in the order of CAD$1.23 billion (initial
capital, excluding access road, including 30% contingency) will likely be required. Investors should note that
there is no certainty that Mont Royal will be able to raise that amount of funding when needed. It is also
possible that such funding may only be available on terms that may be dilutive to or otherwise affect the
value of Mont Royal's existing shares. It is also possible that Mont Royal could pursue other value realisation
strategies such as a sale, partial sale, or joint venture of the Project. If it does, this could materially reduce
Mont Royal's proportionate ownership of the Project.
There is a low level of geological confidence associated with Inferred Mineral Resources and there is no
certainty that further exploration work will result in the determination of Indicated Mineral Resources or that
the production target itself will be realised. Given the uncertainties involved, investors should not make any
investment decisions based solely on the results of the PEA.
Of the approximately 53 Mt of mill feed underpinning the 30-year production target, approximately 93% is
sourced from Indicated Mineral Resources and approximately 7% is sourced from Inferred Mineral Resources.
There is a low level of geological confidence associated with Inferred Mineral Resources and there is no
certainty that further exploration work will result in the determination of Indicated Mineral Resources or that
the production target itself will be realised.
The Inferred Mineral Resources do not feature as a significant proportion early in the mine plan. The mine
plan is sequenced such that Indicated Mineral Resources predominate in the early years of production, with
Inferred Mineral Resources weighted towards the later stages of the mine life. The Company is satisfied that
the respective proportions of Inferred Mineral Resources are not the determining factors in project viability.

Mont Royal’s Managing Director, Mr. Nicholas Holthouse, said:
“The updated PEA marks a major step forward for the Ashram Project, confirming a large-scale, long-
life development with strong underlying economics and a clear pathway to advancement. The study has
highlighted Ashram’s combination of scale, favourable mineralogy and competitive cost profile,
supporting its potential to become a meaningful long-term supplier of rare earth products into Western
supply chains. Importantly, we see further upside beyond the base case, including opportunities in
fluorspar, resource expansion and downstream partnerships and collaboration.
This is a project that can have a meaningful and long-lived impact on the development of rare earth
industries and technologies within Quebec, Canada, North America and Europe.
Our focus now is continuing to work with First Nations and Government agencies on developing
infrastructures strategies and on progressing the project into pre-feasibility, advancing permitting and
continuing engagement with strategic and offtake partners.”

PRELIMINARY ECONOMIC ASSESSMENT OVERVIEW
Mont Royal Resources Limited (ASX: MRZ,TSXV: MRZL) (“Mont Royal” or the “Company”) is pleased
to present an updated Preliminary Economic Assessment (“PEA”) for its 100%-owned Ashram Rare
Earths and Fluorspar Project located in Nunavik, Québec, Canada.
The PEA was completed by Altris Engineering (“Altris”) in accordance with National Instrument 43-
101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) in collaboration with the following
specialist firms:
• Altris Engineering
• BBA Inc. (BBA)
• PLR Resources Inc. (PLR)
• DRA Americas Inc. (DRA)
• L3 Process Development (L3)
• ASDR Canada Inc.
• TALA Geotec
• Norda Stelo Inc.
The updated study incorporates significant optimisation work completed since prior economic
studies, including:
• revised mining and processing assumptions;
• optimisation of transportation and logistics pathways;
• incorporation of a proposed hydrometallurgical processing facility in Saguenay, Québec;
• updated infrastructure assumptions; and
• revised engineering and metallurgical inputs.
The PEA highlights the potential for Ashram to become a major long-term supplier of rare earth
products into Western and allied critical mineral supply chains.
Ashram is one of the largest monazite-hosted rare earth deposits in North America and contains a
favourable distribution of magnet rare earth elements, including neodymium and praseodymium
(“NdPr”), which are critical components used in EVs, permanent magnets, wind turbines, robotics,
semi-conductors, aerospace technologies and defence applications.

PROJECT OVERVIEW AND HISTORY
The Ashram Project is located on Mont Royal Resources’ 100%-owned Eldor Property in Nunavik,
northern Québec, approximately 130km south of Kuujjuaq, and covers 11,475ha across 244
contiguous Exclusive Exploration Rights (EERs) as shown in Figure 1.
Figure 1: Ashram REE and Fluorspar Project location
6
The Project hosts the Eldor Carbonatite Complex, including the Ashram Rare Earth and Fluorspar
Deposit, with additional potential for niobium, tantalum and phosphate mineralisation.
Following the merger between Commerce Resources and Mont Royal Resources in October 2025,
the combined group consolidated ownership and strategic direction for the Project.
Commerce Resources Corporation holds a 100% interest in all EERs, which are in good standing
until May 2027. Importantly, the Ashram Deposit is not subject to the limited third-party royalties
applicable to a small number of original claims. The Property is fully permitted for exploration, with
no known material environmental, legal or access constraints.
The Project is accessible via Kuujjuaq, which serves as the primary logistics hub with regular air
services from Montréal and seasonal marine supply access. A permanent on-site exploration
facility, Camp Valcourt, supports year-round operations and accommodates up to 35 personnel.
The Project benefits from several strategic infrastructure advantages, including:
• access to established logistics corridors;
• proximity to potential port infrastructure;
• access to low-cost renewable hydroelectric power in Québec (Saguenay site);
• a supportive mining jurisdiction; and
• access to established industrial infrastructure in Saguenay.
Since acquiring the Property in 2007, Commerce has completed extensive drilling, geophysical
surveys, trenching and surface exploration programs.
The Ashram REE Deposit was discovered in 2009, with subsequent drilling confirming a large-scale,
continuous mineralised system extending from surface to depth.
This work supported the establishment of NI 43-101 compliant Mineral Resource Estimates, which
have since positioned Ashram as one of the largest undeveloped rare earth deposits in North
America.
GEOLOGICAL SETTING
Ashram is hosted within the Eldor Carbonatite Complex, a large intrusive carbonatite system
located within the Paleoproterozoic New Québec Orogen.
Rare earth mineralisation is dominated by monazite, with subordinate bastnäsite, parisite and
xenotime. The relatively simple and commercially favourable mineral assemblage is considered
advantageous for metallurgical recovery and downstream processing.
The deposit includes several mineralised zones, including:
• A-Zone;
• B-Zone;
• Breccia Zone; and
• BD-Zone.
These zones vary in texture and grade, with the A‑Zone hosting the highest and most continuous
REE grades. Niobium and tantalum mineralisation occurs elsewhere in the complex, mainly hosted
in pyrochlore‑group minerals within carbonatite and phoscorite units.
7
The relatively simple mineral assemblage is considered commercially favourable and comparable
to other major carbonatite-hosted REE systems globally, including Mountain Pass (USA), Niobec
(Québec) and Palabora (South Africa).
MINERAL RESOURCE ESTIMATE
The updated PEA uses the updated JORC MRE for the Ashram Deposit released on October 1,
2025 (Table 3). The Ashram MRE integrates drilling data collected between 2008 and 2022 and
was completed using industry‑standard geological modelling and geostatistical methods.
A total database of 213 drill holes, six surface channels, and nearly 33,000 samples underpin the
estimate, with mineralisation defined within three REE‑bearing domains (A‑Zone, B‑Zone, and
Breccia Classic). The drill hole collars are shown below in Figure 2.
Figure 2: Carbonatite Complex Geology of the Ashram Project.
8
Ordinary kriging was applied within a detailed 3D block model constrained by a conceptual
open‑pit shell developed to demonstrate reasonable prospects for eventual economic extraction.
The estimate is classified in accordance with CIM standards, defining Indicated and Inferred
Resources based on drill spacing, geological confidence, and grade continuity; no Measured
Resources are defined at this stage. The confidence categories assigned under the CIM Definition
Standards were reconciled to the confidence categories under the JORC Code, as disclosed in the
Company’s Prospectus released to ASX on 1 October 2025.
Interpreted zones are shown below in the cross-section in Figure 3 with Figure 4 showing the block
model coloured by resource classification within the resource shell.

considered in the MRE.

Figure 4: Cross-section showing Indicated and Inferred classifications within the block model.
Figure 5: Cross-section showing the TREO % distribution.
Using a base case, net metal return (NMR) cut‑off of CAD$287/t, the MRE defines 73.2 Mt of
Indicated Resources grading 1.89% Total Rare Earth Oxides (TREO) and 131.1 Mt of Inferred
Resources grading 1.91% TREO. The resource exhibits a favourable rare‑earth distribution, with
NdPr accounting for approximately 21% of TREO and meaningful contributions from the critical
heavy rare earths Tb and Dy with Figure 5 showing TREO distribution.
Mineralisation remains open laterally and at depth, and the estimated pit shell outlines a large,
continuous deposit with a conceptual strip ratio across the entire MRE of approximately 2.7:1.

The MRE confirms Ashram as a large, well-defined rare earth deposit with strong grade continuity
and favourable metallurgical characteristics. The BD-Zone, also an REE-bearing unit, was excluded
from the estimate pending further metallurgical evaluation and therefore represents additional
resource upside.
Overall, the MRE provides a solid basis for advanced technical studies and future resource
definition through continued drilling.
11
DEVELOPMENT PATHWAY
The updated PEA contemplates a mine and concentrator operation located at Ashram, with
production of an intermediate mixed rare earth concentrate (“MREC”) product for downstream
processing.
The Project development strategy incorporates:
• on-site concentration;
• multi-modal logistics transportation;
• hydrometallurgical processing in Saguenay;
• production of saleable mixed rare earth products; and
• future optionality for additional downstream processing initiatives.
The Company believes this approach:
• materially improves execution certainty;
• reduces development complexity;
• enhances scalability;
• supports financing pathways; and
• aligns with broader Québecois and Canadian critical minerals strategies.
MINING
The Ashram Project mine design and mine plan are based on a conventional open-pit, truck-and-
shovel operation using drill-and-blast mining on 10m benches, operated by an owner fleet on a
continuous 7-day, 12-hour shift basis.
While the Mineral Resource supports a theoretical 169-year mine life at 4,900tpd, a 30-year life-of-
mine (LOM) was adopted for the PEA as it captures most of the Project’s value. Based on technical
and economic parameters and metal selling prices, the Net Metal Return (NMR) cut-off for the
Project was calculated at CAD$88/t.
A trade-off study assessing the impact of higher cut-off values on Project economics and
concentrator feed quality resulted in the selection of an elevated cut-off strategy being adopted
and an NMR cut-off of CAD$217/t was ultimately selected for the PEA.
The resulting open pit design for the 30-year mine life includes 53 Mt of mill feed at a strip ratio of
0.4:1. Access to mineralisation beneath the shallow centre pond will require the construction of
dewatering dykes and controlled pond dewatering. Mine design, scheduling and cost estimation
were completed using MinePlan 3D software, supported by geological, topographical and material
property data.
Of the approximately 53 Mt of mill feed underpinning the 30-year production target, approximately
93% is sourced from Indicated Mineral Resources and approximately 7% is sourced from Inferred
Mineral Resources. There is a low level of geological confidence associated with Inferred Mineral
Resources and there is no certainty that further exploration work will result in the determination of
Indicated Mineral Resources or that the production target itself will be realised.
The mine plan has been sequenced such that Indicated Mineral Resources predominate in the early
years of production, with Inferred Mineral Resources weighted towards the later stages of the mine
life. The Company is satisfied that the respective proportions of Inferred Mineral Resources are not
12
the determining factors in project viability and that Inferred Mineral Resources do not feature as a
significant proportion early in the mine plan.
A phased mining approach was developed to prioritise higher-value material and manage
technical risk, commencing with a starter pit that can be mined prior to the full dewatering of the
centre pond from Year 2 to Year 3, followed by two deeper mining phases to a final pit depth of
approximately 240m.
The mine plan targets steady-state production of 1.8Mtpa following a staged ramp-up, with
average total material movement of 2.5Mtpa over the LOM. Waste rock, low-grade material and
topsoil will be strategically stockpiled, with waste rock largely utilised for tailings dyke construction.
Mining fleet requirements and workforce estimates underpin the mining cost model used in the
PEA financial analysis.

METALLURGY AND PROCESSING
Minerals Processing Testing and Results
Several mineral processing test work programs have been completed for the Ashram Project to
develop a beneficiation flowsheet capable of producing a rare earth mineral concentrate suitable
for cost-effective hydrometallurgical processing.
The objectives of the various test work programs differed, with some focused on producing a high-
grade mineral concentrate, while others investigated generating a lower-grade concentrate to
maximise REE recovery and produce a fluorspar by-product.
The current beneficiation flowsheet strategy for REE processing is focused on producing a high-
grade mineral concentrate to reduce the complexity and cost of downstream hydrometallurgical
processing. This flowsheet does not consider fluorspar by-products.
Historical metallurgical test work campaigns were undertaken at UVR-FIA GmbH in Germany,
Université Laval in Québec City, Canmet MINING in Ottawa, and Hazen Research Inc. in Colorado,
USA. SGS Canada was subsequently engaged to investigate alternative flowsheets based on the
historical work and the current project objectives.
SGS completed several test programs, including sample preparation, mineral characterisation,
comminution testing, batch and locked-cycle flotation testing, and solid-liquid separation testing.
The SGS work programs formed the basis for the process design criteria and support the
production of high-grade rare earth mineral concentrates.
Hydrometallurgical Testing and Results
Extensive bench-scale and scoping metallurgical test work has been completed to evaluate
hydrometallurgical recovery pathways for the Ashram flotation concentrate and support flowsheet
selection for the PEA.
Early development work by Hazen (Gagnon et al., 2012) successfully demonstrated the production
of commercial-grade mixed rare earth carbonate via a multi-step process incorporating pre-
leaching, magnetic separation, sulphuric acid bake and water leach, selective thorium removal via
solvent extraction, rare earth extraction and purification, oxalate precipitation, and metathesis to
carbonate. High recoveries were achieved across most rare earth elements.
The flowsheet was subsequently simplified, optimised and validated through test work undertaken
by L3 Process Development. Key processing steps were refined and de-risked, demonstrating
effective gangue removal during pre-leach, strong and acid-efficient acid bake performance, and
high water-leach recoveries. Thorium was completely and selectively extracted and recovered
using Cyanex 923 without significant REE losses.
Additional scoping studies assessed alternative processing concepts, including high-activity direct
hydrochloric acid leaching of flotation concentrates.
While it was successful on earlier flotation concentrates, this approach proved sub-optimal on
concentrates generated under the latest flotation flowsheet conditions, reflecting changes in
concentrate grade, mineralogy and impurity levels.
The cumulative test work confirms the technical robustness of the selected recovery flowsheet and
highlights clear optimisation opportunities to be advanced during the Pre-Feasibility Study.

On-site Mineral Processing Facility
The Ashram Rare Earth Element Mineral Processing Facility (“MPF” or “concentrator”) will be
located immediately north of the open pit mine. The concentrator will comprise crushing, grinding,
flotation and dewatering circuits.
The facility is designed to process nominal throughput of 4,900 dry tonnes per day (tpd) of run-of-
mine (ROM) mineralised material at an average feed grade of 1.88% rare earth oxide (“REO”),
producing approximately 190tpd of concentrate grading around 30% REO, varying between 28%
and 34% depending on feed grade.

The concentrator is designed to achieve an average REO recovery of 63% based on flotation test
work, although recovery is expected to vary according to feed composition. Filtered concentrate
will be loaded into 20-foot containers and transported south to the hydrometallurgical processing
facility at Saguenay. Concentrator tailings, referred to as processed carbonatite, will be thickened
and pumped to the processed carbonatite storage facility.
Figure 10 above shows concentrator tonnes and grades recovered onsite for shipment to
Saguenay by years.
Hydrometallurgical Processing Facility
The hydrometallurgical processing facility, to be located in Saguenay, will upgrade flotation
concentrate into a Mixed Rare Earth Carbonate (MREC) product using a proven process route
incorporating acid bake, water leach, solvent extraction, oxalate precipitation and metathesis.
The hydromet plant is designed to process approximately 69,500tpa of flotation concentrate and
produce approximately 33,800tpa of MREC, while ensuring effective removal and management of
thorium and other impurities.
Process design is based on preliminary heat and material balance modelling and metallurgical test
work, with individual circuit recoveries resulting in overall rare earth recoveries typically ranging
from approximately 72% to more than 90%, depending on the element.
Comprehensive effluent treatment, scrubbing and reagent management systems have been
incorporated to meet environmental and safety requirements.
Together, the concentrator and hydromet facilities form a technically robust recovery flowsheet that
supports the Project’s production targets and provides a clear pathway from mine feed to a
marketable rare earth product at the PEA level.

INFRASTRUCTURE
The Ashram Project infrastructure strategy is underpinned by a comprehensive transport and
logistics framework designed to support a remote mining operation with limited existing
infrastructure and services in the surrounding region.
A 2025 transport route trade-off study identified a southern logistics corridor as the preferred
development pathway. Under this scenario, concentrate would be transported via a 320km road
link from Ashram to Schefferville, where it would connect to existing rail infrastructure for shipment
to Sept-Îles. From there, containerised concentrate would be transported approximately 570km
either by road or marine transport along the St. Lawrence River to Saguenay.
This intermodal logistics solution is designed to provide reliable, year-round transport while
avoiding reliance on the previously considered northern shipping route, which would have
required construction of new port infrastructure.
Transport logistics consider the naturally present thorium radionuclide content, which becomes
concentrated during mineral processing on site at Ashram. The beneficiate concentrate will leave
the Ashram mine-concentrator site as a class 7 material. During hydrometallurgical processing,
thorium is expected to be concentrated into a separate, stable product (approximate 35% thorium
oxide), while the final MREC product will contain very low thorium levels and is not expected to
trigger radioactive transport regulations. The stable thorium-rich material will be transported
separately to any other product or waste stream for disposal in Saskatoon in a third party approved
and permitted radionuclide storage facility.
Supporting mine site infrastructure includes internal access roads, an aerodrome, diesel-based
power generation, telecommunications systems, fuel storage, explosives facilities, and
administrative and accommodation buildings for a workforce of up to 200 personnel.
Mont Royal is currently exploring options to share the infrastructure development with other local
mining projects, government agencies, and First Nations.
At the downstream Saguenay site, additional non-process infrastructure will sup
