71.8 g/t Au over 31.95 m and 76.6 g/t Au over 16.00 m at Iceberg 51.3 g/t Au over 3.40 m and 11.8 g/t Au over 9.95 m at Keats

New Found Gold Corp. (TSXV: NFG) (NYSE American: NFGC) (‘New Found Gold’ or the ‘Company’) is pleased to announce the final results of the Company’s 2025 grade control drill program on its 100%-owned Queensway Gold Project (‘Queensway’ or the ‘Project’) in Newfoundland and Labrador, Canada, including results from the Keats zone (‘Keats’) and Iceberg zone (‘Iceberg’) excavations in the AFZ Core (‘AFZC’), completed as part of the Company’s 2025 drill program.

Iceberg excavation highlights include:

 

Keats excavation highlights include:

 

Melissa Render, President of New Found Gold stated: ‘These final results from our highly successful 2025 grade control drill program at the Keats and Iceberg excavations continue to deliver consistently high gold grades over broad widths, returning some of the best intercepts we have drilled to date at Queensway. We continue to systematically de-risk Queensway, as demonstrated by the continuity of high-grade gold mineralization in these at-surface zones targeted for early open pit mining in our 2025 PEA Phase 1 mine plan.’

Work Summary

The results presented in this release include the final 907 m of drilling in 32 diamond drill holes (‘DDH‘) from the Keats excavation (‘KEGCDP‘) and the entirety of the 2,390 m of drilling in 40 DDH from the Iceberg excavation (‘IEGCDP‘) 2025 grade control drill program (Figures 1 to 4). The KEGCDP and IEGCDP were designed to improve confidence in the distribution of high-grade, near- to at-surface gold mineralization and support mine planning as outlined in the 2025 Preliminary Economic Assessment (‘PEA‘) Phase 1 open pits (see the New Found Gold press release dated July 21 2025). Drill highlights, along with detailed results for these 72 DDH, are provided in Tables 1 to 3 below.

The full KEGCDP comprises 2,773 m in 84 DDH; for the previously reported KEGCDP results see the New Found Gold press releases dated December 1, 2025 and February 2, 2026 and highlights below. The full IEGCDP comprises 2,390 m of drilling in 40 DDH and all results are reported in this press release.

The KEGCDP tested a volume that is approximately 65 m long by 30 m deep by 40 m wide and the IEGCDP a volume that is approximately 60 m long by 35 m deep by 40 m wide with a drill spacing of 5 m by 5 m and includes the near- to at-surface high-grade portions of Keats and Iceberg that were exposed as part of the Company’s excavation programs (see the New Found Gold press releases dated September 23, 2024, December 2, 2024, September 25, 2025, December 1, 2025 and February 2, 2026).

Results released to date correlate well with the initial mineral resource estimate (‘MRE‘) block model and indicate strong continuity of -high grade mineralized shoots at both Keats and Iceberg, providing improved definition of their geometry, with most intervals occurring at or within a few meters of surface. The detailed geostatistical data from this phase of work will further validate the resource models, specifically by increasing confidence in grade-capping and influence-limiting parameters applied to high-grade intersections in advance of a MRE update and subsequent mine planning.

The Keats and Iceberg zones are hosted within the Keats-Baseline Fault Zone (‘KBFZ‘), a high-grade gold-bearing structure that has been defined over a current strike length of 1.9 kilometres (‘km‘). This corridor consists of a broad mineralized fault zone with limited deep drill testing to date. Drilling completed in 2024 confirms that the system extends to vertical depths of up to 1.1 km (see the New Found Gold press releases dated July 11, 2024, October 31, 2024, and April 29, 2025).

Looking Ahead

The 2025 Queensway drill program included 74,377 m of drilling in 614 DDH, with approximately 75% of the drilling focused on the AFZC to support advancement of the Phase 1 mine plan as outlined in the PEA and 25% focused on exploration targets such as the Dropkick zone (‘Dropkick‘). To date, approximately 45% of the results from 2025 drilling remain outstanding, in addition to channel sampling results from the Lotto excavation. These results will be reported once available.

The 2026 Queensway drill program is underway, with four drill rigs currently active (see the New Found Gold press release dated January 21, 2026). Initial 2026 infill drilling is planned to first target PEA Phase 2 open pit resource conversion, transitioning later in the year to PEA Phase 3 underground resource conversion.

The Company plans to expand its grade control drilling beginning in Q2/26. The next phase of work will leverage results from the 2025 program to optimize drill hole spacing and program scope. This will include completing grade-control drilling at the Iceberg excavation, commencing grade-control drilling at the Lotto excavation and potentially expanding the grade-control drilling at the Keats and Iceberg excavations. The objective of this work is to improve confidence in the distribution of gold mineralization and support mine planning as outlined for the PEA Phase 1 open pits.

Exploration drilling will focus on AFZC resource expansion including an initial grid-based program targeting the prospective corridor adjacent to the AFZ at Bullseye, continued step-outs at Dropkick, located 11 km north of the AFZC, and targeted segments of the AFZ at AFZ Peripheral. A regional drilling program testing advanced targets at Queensway South is in the planning phase and expected to commence in H2/26.

The Company plans to file an updated Technical Report for Queensway, which will include an updated mineral resource estimate, in Q3/26

Note that the host structures are interpreted to be moderately to steeply dipping. Infill veining in secondary structures with multiple orientations crosscutting the primary host structures are commonly observed in drill core which could result in additional uncertainty in true width. Composite intervals reported carry a minimum weighted average of 1 g/t Au diluted over a minimum core length of 2 m with a maximum of 4 m consecutive dilution when above 200 m vertical depth and 2 m consecutive dilution when below 200 m vertical depth. Included high-grade intercepts are reported as any consecutive interval with grades greater than 10 g/t Au. Grades have not been capped in the averaging and intervals are reported as drill thickness. Details of all drill holes reported in this press release are included in Table 2 and Table 3 below.

Sampling, Sub-sampling, and Laboratory

All drilling recovers HQ core. For deep holes, the core size may be reduced to NQ at depth. The drill core is split in half using a diamond saw or a hydraulic splitter for rare intersections with incompetent core.

A geologist examines the drill core and marks out the intervals to be sampled and the cutting line. Sample lengths are mostly 1.0 meter and adjusted to respect lithological and/or mineralogical contacts and isolate narrow (<1.0m) veins or other structures that may yield higher grades.

Technicians saw the core along the defined cutting line. One half of the core is kept as a witness sample and the other half is submitted for analysis. Individual sample bags are sealed and placed into totes, which are then sealed and marked with the contents.

New Found Gold has submitted samples for gold determination by PhotonAssay to ALS Canada Ltd. (‘ALS‘) since February 2024. ALS operates under a commercial contract with New Found Gold.

Drill core samples are shipped to ALS for sample preparation in Thunder Bay, Ontario. ALS does not currently have accreditation for the PhotonAssay method at their Thunder Bay, ON laboratory. They do however have ISO/IEC 17025 (2017) accreditation for gamma ray analysis of samples for gold at their Australian labs with this method, including the Canning Vale lab in Perth, WA.

Samples submitted to ALS beginning in February 2024 received gold analysis by photon assay whereby the entire sample is crushed to approximately 70% passing 2 mm mesh. The sample is then riffle split and transferred into jars. For ‘routine’ samples that do not have VG identified and are not within a mineralized zone, one (300-500g) jar is analyzed by photon assay. If the jar assays greater than 0.8 g/t, the remaining crushed material is weighed into multiple jars and submitted for photon assay.

For samples that have VG identified, the entire crushed sample is riffle split and weighed into multiple jars that are submitted for photon assay. The assays from all jars are combined on a weight-averaged basis.

Select samples prepared at ALS are also analyzed for a multi-element ICP package (ALS method code ME-ICP61) at ALS Vancouver.

Drill program design, Quality Assurance/Quality Control, and interpretation of results are performed by qualified persons employing a rigorous Quality Assurance/Quality Control program consistent with industry best practices. Standards and blanks account for a minimum of 10% of the samples in addition to the laboratory’s internal quality assurance programs.

Quality Control data are evaluated on receipt from the laboratories for failures. Appropriate action is taken if assay results for standards and blanks fall outside allowed tolerances. All results stated have passed New Found Gold’s quality control protocols.

New Found Gold’s quality control program also includes submission of the second half of the core for approximately 2% of the drilled intervals. In addition, approximately 1% of sample pulps for mineralized samples are submitted for re-analysis to a second ISO-accredited laboratory for check assays.

The Company does not recognize any factors of drilling, sampling, or recovery that could materially affect the accuracy or reliability of the assay data disclosed.

The assay data disclosed in this press release have been verified by the Company’s Qualified Person against the original assay certificates.

All amounts in Canadian dollars unless stated otherwise.

Vancouver, British Columbia–(Newsfile Corp. – March 2, 2026) – Allied Critical Metals Inc. (CSE: ACM,OTC:ACMIF) (OTCQB: ACMIF) (FSE: 0VJ0) (‘Allied‘ or the ‘Company‘) is pleased to announce the results of its initial Preliminary Economic Assessment (‘PEA‘) for its 100%-owned Borralha Tungsten Project (‘Borralha‘ or the ‘Project‘) in northern Portugal.

‘The completion of the PEA marks another important milestone for the Company. In addition to the significant tailwinds provided by the significant increase in the price of tungsten, which has surged to more than USD $1,900/mtu [Source: Fastmarkets], we are very pleased to see have been able to receive support from idD Portugal Defence, the Portuguese public entity overseeing the nation’s Defence Industry, which has endorsed the Borralha Project as a strategic initiative of national importance. We have also received a favourable Environmental Impact Declaration, subject to standard regulatory conditions (Declaração de Impacte Ambiental Favorável Condicionada – ‘DIA’) from the Portuguese Environment Agency (Agência Portuguesa do Ambiente, I.P. – APA),’ commented Roy Bonnell, CEO and Director of Allied. ‘We could not be more pleased with the considerable advancement of the Borralha Project and look forward to continuing to more progress at the Borralha Project and the Vila Verde Project, which are both strategic critical mineral tungsten assets well positioned within the EU.’

The PEA outlines a technically robust and capital-efficient underground tungsten development project within the European Union, delivering strong economics across a range of pricing assumptions. Importantly, the study reflects only the Santa Helena Breccia deposit and an initial 11-year mine plan. The Company is committed to long term expansion of the current resource estimate and as such has recently commenced a fully funded 20,000-metre drill program designed to expand the current resource and enhance long-term project scale.

• Potential extension of mine life beyond 11 years

• Evaluation of throughput optimization and scale growth

The Company views this initial PEA as a foundational step in what is expected to be a multi-stage growth strategy at the Borralha Project.

Roy Bonnell, CEO & Director commented, ‘This initial PEA confirms the Borralha Project as a high-return, capital-efficient tungsten development project in a Tier-1 European jurisdiction. At USD $1,000 per mtu (significantly below current reported market pricing) the Borralha Project generates a 48.8% after-tax IRR with modest initial capital of approximately USD $91 million.

Importantly, this PEA reflects only the Santa Helena Breccia and an initial 11-year mine plan. With future exploration work and the 20,000 meters of drilling currently underway, we are focused on expanding resources, extending mine life and enhancing overall project scale. We believe we are at the beginning of unlocking the Borralha Project’s full potential.

Combined with a favourable Environmental Impact Declaration, we believe that this PEA opens the door to project level financing for both our industrial scale plant and our pilot plant at the Vila Verde Project.’

Introduction

This initial PEA contemplates development of an underground mining operation at the Santa Helena Breccia deposit within Borralha with a nominal processing capacity of 1.4 million tonnes per annum, utilizing conventional crushing, grinding and gravity concentration to produce a saleable Wolframite concentrate grading approximately 65% WO₃.

The Borralha Project has received a favourable Environmental Impact Declaration (‘DIA’), materially advancing permitting and reducing development risk relative to many global tungsten projects.

Economic Summary

This initial PEA was developed using three pricing frameworks: (i) Low/Base Case: Argus long-term forecast (variable annually) averaging approx. USD $704 per mtu WO₃; (ii) USD $1,000 per mtu WO₃; and (iii) USD $1,500 per mtu WO₃.

Mine design and cut-off grade selection were developed using a conservative price assumption of USD $659 per mtu WO₃.

1. Project Overview

The Borralha Tungsten Project is located in the parish of Salto, municipality of Montalegre, district of Vila Real, Portugal. The project comprises a continuous exploitation concession area of approximately 382.48 hectares (3.82 km²).

This initial PEA has been prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (‘NI 43-101‘) and is based on the updated Mineral Resource Estimate for the Santa Helena Breccia, effective December 30, 2025. See Company’s current technical report on Borralha (the ‘Technical Report‘) entitled ‘Technical Report on the Borralha Property, Parish of Salto, District of Vila Real, Portugal’, dated effective December 30, 2025, which is published on the Company’s website at www.alliedcritical.com and under its profile on SEDAR+ at www.sedarplus.ca.

Borralha represents one of the largest undeveloped tungsten resources within the European Union and benefits from gravity-dominant processing, reducing metallurgical risk relative to flotation-dependent systems. The project aligns with European critical raw material supply objectives.

2. Mineral Resource Estimate

This initial PEA is based on the updated Mineral Resource Estimate (‘MRE‘ or ‘2025 MRE‘) for the Santa Helena Breccia, which were presented in accordance with NI 43-101 in the Company’s current Technical Report.

Mineral Resources are reported in situ and undiluted and do not incorporate modifying factors such as mining dilution, mining recovery, metallurgical recovery, capital costs, operating costs, or economic analysis. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

MRE Cut-off Grade: 0.09% WO₃

The cut-off grade was selected based on reasonable prospects for eventual economic extraction under conceptual underground mining and gravity-dominant processing assumptions, including a very conservative tungsten price of USD$ 550/mtu WO₃ and assumed recovery of approximately 80% (for MRE cut-off determination only). The 2025 MRE reflects a material increase in tonnage and geological confidence relative to the previous mineral resource estimate published in March 2024.

Under the 2025 MRE, the Santa Helena Breccia has been tested by 41 drill holes and surface trenching over approximately 400 meters of strike length and to depths exceeding 350 meters below surface. Mineralization remains open along strike and at depth.

Table 2 — 2025 MRE for Borralha (see also Technical Report for further details)

 

3. Mining Method and Production Plan

3.1 Selected Mining Method

The planned mining method for the Santa Helena Breccia involves using mostly long-hole open stoping with cemented paste backfill. This method was selected based on: (i) steeply dipping geometry of the breccia-hosted mineralization; (ii) demonstrated geological continuity; (iii) favorable rock mass conditions; (iv) productivity and operating cost advantages; and (v) reduced surface footprint.

Drift-and-fill mining is incorporated locally in narrower high-grade zones to enhance resource recovery. Open-pit mining and alternative underground methods were evaluated during the conceptual study stage and were not selected due to environmental constraints, scale suitability, and relative operating efficiency.

3.2 Mine Production Schedule

Key operating parameters:

• Nominal processing rate: 1.4 million tonnes per annum
• Estimated mine life: approximately 11 years
• Total life-of-mine processed tonnes: approximately 13.4 million tonnes
• Average life-of-mine mill feed grade: approximately 0.20% WO₃

The production schedule supports consistent mill feed and stable concentrate production throughout the mine life.

Table 3 — LoM Totals and Averages

 

Table 4 — Life-of-Mine Schedule Summary

 

3.3 Dilution and Recovery Assumptions

The mine plan incorporates Measured, Indicated, and Inferred Mineral Resources within a stope optimization framework consistent with long-hole open stoping methods.

Applied modifying factors include:

• Mining dilution: approximately 8% (average between primary and secondary stopes)
• Mining recovery: approximately 89%
  • ~90% for primary stopes
  • ~88% for secondary stopes
• Drift-and-fill: approximately 7.5% dilution and 95% recovery

After application of these factors, the projected average life-of-mine mill feed grade is approximately 0.20% WO₃.

The PEA includes Inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied that would enable them to be categorized as Mineral Reserves. There is no certainty that the results of the PEA will be realized.

Inferred material represents less than approximately 40% of the life-of-mine stope inventory on a volumetric basis and is predominantly located along the margins and outer extents of the deposit.

4. Metallurgy and Processing

4.1 Metallurgical Test Work

Metallurgical test work completed to date indicates that Santa Helena Breccia mineralization is amenable to gravity-dominant processing.

The initial metallurgical program (2023–2024) evaluated crushing, grinding, sulfide flotation, gravimetric concentration, and magnetic separation. Subsequent optimization reduced reliance on flotation by incorporating dense media separation (‘DMS‘) pre-concentration and enhanced gravity recovery.

4.2 Process Flow Sheet

The proposed process plant includes:

• Three-stage crushing to approximately 6 mm
• DMS pre-concentration on the 6–2 mm fraction (rejecting approximately 40% of mass)
• Grinding of DMS product and -2 mm fraction to 1 mm
• Gravimetric concentration using spirals and shaking tables
• Magnetic and electrostatic separation for final concentrate upgrading
• Flotation circuit for copper and tin recovery
• Filtered tailings with dewatering and partial paste backfill return underground

4.3 Recovery and Concentrate Grades

Preliminary metallurgical recovery estimates:

• Tungsten: 75%
• Copper: ~60%
• Tin: 30%

Expected concentrate specifications:

• Tungsten concentrate: ~65% WO₃
• Copper concentrate: ~21% Cu
• Tin concentrate: ~50% Sn

Silver credits may partially report to the copper concentrate, subject to further test work confirmation.

5. Infrastructure and Site Requirements

The Borralha Project benefits from:

• Regional road access
• Grid power availability
• Underground mining configuration minimizing surface disturbance
• Filtered dry-stack tailings concept
• Closed-loop water management system

6. Environmental and Permitting

In January 2026, the Portuguese Environment Agency issued a Favourable Environmental Impact Declaration (‘DIA‘) for the Borralha Project, subject to standard regulatory conditions.

This milestone confirms environmental acceptability of the proposed development and enables progression to the RECAPE stage and subsequent construction permitting.

The Borralha Project aligns with European Union critical raw material strategy and contributes to regional economic development objectives.

7. Economic Framework

7.1 Pricing Framework

The life-of-mine design, cut-off grade selection and production schedule were developed using a conservative tungsten price assumption of USD $659 per metric tonne unit (‘mtu‘) WO₃, consistent with the Argus long-term base case forecast. The Base Case economic model applies the Argus high-case long-term forecast on a year-by-year basis, ranging from approximately USD $763 per mtu in 2028 and gradually declining toward approximately USD $677 per mtu by 2040, for an average price of approximately USD $704 per mtu. [Source: Argus Media Group.]

This approach maintains a conservative technical design basis while allowing the economic analysis to reflect updated long-term market expectations without re-optimizing mine geometry.

Flat price sensitivity scenarios at USD $1,000/mtu and USD $1,500/mtu WO₃ are presented for comparative purposes.

7.2 Operating Cost Summary

The Borralha Project is based on conventional underground mining and gravity-dominant processing, resulting in a competitive cost structure.

Life-of-mine average operating costs⁷ are estimated at:

• US$49 per tonne processed
• Equivalent to approximately USD $245 per mtu WO₃ produced (based on a 0.20% average mill feed grade and 75% metallurgical recovery)

Operating cost components include:

• Underground mining
• Processing and plant operations
• General and administrative costs
• Site services and infrastructure support

The cost structure incorporates modifying factors of approximately 8% mining dilution, 89% mining recovery, and 75% metallurgical recovery.

7.3 All-In Sustaining Cost (AISC)

The Project’s estimated all-in sustaining cost⁸, inclusive of sustaining capital and site-level costs, is approximately: USD $303 per mtu WO₃.

This positions the Borralha Project competitively within the global tungsten cost curve.

7.4 Capital Costs

The PEA estimates capital costs⁹ as follows:

• Initial capital cost: approximately USD $91 million (CAD $124.3 million)
• Sustaining capital: approximately USD $87 million (CAD $118.8 million)
• Total life-of-mine capital: approximately USD $178 million (CAD $243.1 million)

Capital estimates are preliminary in nature and carry an accuracy range of ±35%, consistent with PEA-level studies.

7.5 Economic Metrics (After-Tax)

1. NPV is a Non-GAAP measure; see notes below for additional information regarding NPV.
2. IRR is a Non-GAAP measure; see notes below for additional information regarding IRR.
3. Payback is a Non-GAAP measure. see notes below for additional information regarding payback.
4. Canadian dollar (CAD) equivalents calculated used a foreign exchange rate of CAD $1.3658/USD.

Mine design and cut-off grade selection were developed using a conservative USD $659/mtu WO₃ assumption. Recent reported tungsten market prices have reached approximately USD $1,998/mtu [Source: Fastmarkets; February 27, 2026], demonstrating meaningful leverage to current market conditions.

7.6 Sensitivity Analysis

Sensitivity analysis demonstrates that Project economics are most sensitive to: (i) tungsten price; (ii) capital costs; (iii) operating costs; and (iv) metallurgical recovery.

The Project retains positive economics across a range of tungsten price assumptions. At the Base Case price assumption, the Project generates robust operating margins, with significant leverage to higher tungsten price scenarios.

The Project demonstrates strong leverage to tungsten price. The following sensitivity analysis illustrates the post-tax IRR and NPV (8%) across a flat tungsten price range of USD $500 to USD $1,700 per mtu WO₃.

8. Growth and Expansion Opportunities

Mineralization at the Santa Helena Breccia remains open along strike and at depth, providing potential for future Mineral Resource expansion through additional drilling. The current underground mine design is based on the defined Mineral Resource; however, further infill and step-out drilling may support resource conversion and potential extension of mine life. The process plant has been designed at a nominal throughput of 1.4 Mtpa. Subject to further engineering studies and market conditions, the plant layout may allow for future throughput expansion. Selective mining and continued geological refinement may enhance grade control and support optimization of the life-of-mine grade profile.

9. Strategic Positioning

The Borralha Project represents one of the largest undeveloped tungsten resources within the European Union and is positioned to contribute to European supply chain security for this designated critical raw material. The combination of underground mining, gravity-dominant processing and significant permitting advancement materially reduces technical and development risk relative to many global tungsten development projects.

The favourable Environmental Impact Declaration (DIA) provides regulatory clarity and supports advancement toward the next stage of engineering and feasibility.

10. Project Risks and Uncertainties

This initial PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied that would enable them to be categorized as Mineral Reserves. There is no certainty that the results of the PEA will be realized.

Key risks and uncertainties include:

• Inclusion of Inferred Mineral Resources within the mine plan
• Variability in tungsten price and foreign exchange rates
• Capital cost escalation and schedule risk
• Metallurgical recovery variability
• Underground geotechnical and hydrogeological conditions
• Regulatory and permitting timelines
• Availability of equipment and human resources

11. Recommended Work Program

The Company intends to advance Borralha toward the next stage of engineering through:

• Infill drilling to upgrade Inferred Mineral Resources to higher confidence categories
• Step-out drilling to expand Mineral Resources and potentially extend mine life.
• Additional metallurgical optimization and variability testing
• Detailed geotechnical and hydrogeological investigations
• Engineering advancement toward a Pre-Feasibility Study
• Ongoing permitting and RECAPE progression

These activities are intended to further de-risk the Borralha Project and support advancement toward a Feasibility Study.

12. Quality Control

The Company has implemented a comprehensive and well-documented quality assurance and quality control (‘QA/QC‘) program consistent with industry best practices. Drill core and reverse circulation samples were prepared at ISO-accredited ALS Global facilities in Seville, Spain, and analyzed at ALS Global’s certified laboratory in Loughrea, Ireland, using XRF methods for tungsten (W-XRF05 and W-XRF10), with routine internal laboratory QA/QC procedures including pulp duplicates. The Company inserted certified reference materials (‘CRMs‘), blank samples, and field duplicates into the sample stream at regular intervals, including one CRM every 20 routine samples and two blanks per analytical batch.

Five independent CRMs covering multiple grade ranges were used. Samples exceeding ±3 standard deviations from expected CRM values, or blanks exceeding three times detection limits, triggered re-assay of the affected batch. Reverse circulation samples were weighed to monitor recovery and reject materials were securely stored. Independent verification sampling by a Qualified Person confirmed the reliability of the analytical database. The Qualified Persons are satisfied that the QA/QC procedures and resulting analytical data are appropriate for use in the Mineral Resource Estimate and the PEA.

Radisson Mining Resources Inc. (TSXV: RDS,OTC:RMRDF) (OTCQB: RMRDF) (‘Radisson’ or the ‘Company’) is pleased to report an updated Mineral Resource Estimate (‘MRE’) at its 100%-owned O’Brien Gold Project (‘O’Brien’ or the ‘Project’) located in the Abitibi region of Québec. The Company is currently undertaking a fully-funded 140,000-metre step-out drill program at the Project with the objective of determining the scope of mineralization to a depth of 2 kilometres. This program commenced in 2025 and is expected to continue through the first half of 2027. Today’s updated MRE is an interim report that demonstrates the impact of recent drilling successes completed as of December 31, 2025. Highlights include:

• 82% increase in Inferred Mineral Resources from step-out drilling intersecting new mineralization, with 1.69 million ounces (‘Moz’) in 10.37 million tonnes (‘Mt’) at 5.08 grams per tonne (‘g/t’) gold (‘Au’);

• 8% increase in Indicated Mineral Resources with 0.63 Moz in 3.49 Mt at 5.59 g/t Au;

• Estimated using US$2,500/oz Au and 2.2 g/t Au cut-off, with a refined geological model and capping strategy, establishing the go-forward basis for future, modern mine development.

Matt Manson, President and CEO: ‘Today we report the first of several planned, step-by-step updates to the MRE at the O’Brien Gold Project, quantifying the impact of our recent drilling success and establishing a clear foundation for future, modern mine development. With just 25% of our 140,000 metre step-out drill program completed, the new vein mineralization delineated beneath the historic mine workings and the previous mineral resource volume (Radisson news release dated February 12, 2026) has resulted in an 82% increase in the quantity of Inferred Mineral Resources, now 1.69 Moz (10.37 Mt at 5.08 g/t Au). At the same time, we have refined the estimate of Indicated Mineral Resources, incorporating more tonnes at a lower average grade for an 8% increase in contained ounces, now 0.63 Moz (3.49 Mt at 5.59 g/t Au). Our estimates utilize a 2.2 g/t Au cut-off at a reasonable gold price assumption of US$2,500/oz.’

‘The former O’Brien Mine was known for high-grade ore-shoots mined in small volumes. Mining ended in 1957 with the gold price at US$35/oz. Significant volumes of mineralized vein material, below what we believe to have been a 7 g/t to 8 g/t Au cut-off, were left untouched. Now, we are presenting the Project as it should be viewed for future development: not as a bespoke deposit of extreme grade and limited scale, but as an extensive Abitibi vein deposit with a substantial inventory of mineralized material amenable to modern mechanized mining at higher throughput.’

‘Our step-out drill campaign at O’Brien is ongoing with up to eight rigs. We expect to complete 72,500 metres in 2026 and 32,500 metres in the first half of 2027. This is in addition to the meterage supporting today’s updated MRE. The vein mineralization system we have been intersecting is open at depth. In fact, since our step-out drilling began in the fall of 2024, we have been seeing an impressive 84% success rate in intercepting classic O’Brien quartz-sulphide-gold veins with grades and thicknesses consistent with today’s updated MRE. Looking to a 2-kilometre exploration floor, we believe an appropriate Exploration Target at O’Brien is another 5 Mt to 10 Mt at grades of between 4.0 g/t and 6.0 g/t Au containing 0.6 Moz to 2.0 Moz. We expect to complete further step-by-step updates to the MRE as our drilling progresses.’

Cautionary statement: Readers are cautioned Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing, or other relevant issues including risks set forth in Radisson’s filings made with Canadian securities regulatory authorities. The potential quantity and grade of an Exploration Target is conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

Mineral Resource Estimate (effective January 31, 2026)

The MRE is based on 428,440 metres of drilling completed to the end of December 31, 2025, and has been authored by SLR Consulting (Canada) Ltd. (‘SLR‘). The estimate utilizes a 2.2 g/t Au cut-off at US$2,500/oz and makes certain assumptions on mining and processing costs, currency exchange rate, and metallurgical recovery (Table 1 and Figure 1). A wireframe vein model prepared by Radisson and reviewed by SLR constrains the estimate and applies a minimum width of 1.2 metres. Individual assays are capped at 60 g/t Au prior to compositing to full width of the veins, and the block model utilizes 5 by 2 by 5 metre blocks consistent with recent mine design studies.

Table 1: Mineral Resource Estimate, Effective January 31, 2026

 

An MRE for the Project was previously published in March 2023 (Radisson news release dated March 2, 2023) based on 325,509 metres of drilling completed to the end of 2022. Indicated Mineral Resources (effective March 2, 2023) were estimated at 0.50 Moz (1.52 Mt at 10.26 g/t Au) with additional Inferred Mineral Resources of 0.45 Moz (1.60 Mt at 8.66 g/t Au). The 2023 study applied a 4.5 g/t Au cut-off at US$1,600/oz Au.

In July 2025, Radisson published a Preliminary Economic Assessment (‘PEA‘) for the Project that utilized the 2023 estimate re-blocked by SLR in the Z-direction from 10 metres to 5 metres to allow for more flexible underground mine design. A cut-off of 2.2 g/t Au at US$2,000/oz Au and an updated set of economic criteria were applied in the re-blocking exercise consistent with the parameters used for the optimization of the PEA’s underground mine schedule. No other changes were made. Indicated Mineral Resources (effective May 6, 2025) were estimated at 0.58 Moz (2.20 Mt at 8.22 g/t Au) with additional Inferred Mineral Resources of 0.93 Moz (6.67 Mt at 4.35 g/t Au).

The updated MRE released today benefits from 66,387 metres of additional drilling in 122 drill holes conducted between 2023 and 2025, which is the most significant factor in the increase of Inferred Mineral Resources (Figure 2). Radisson has also validated an additional 36,544 meters of historic drilling. The updated MRE utilizes similar estimation parameters to previously, but a more restrictive approach to capping. In the March 2023 estimate, and as incorporated in the re-blocked May 2025

estimate, capping at 40 g/t Au was applied to the full-length composites. In the updated MRE, capping has been applied at 60 g/t Au to the underlying assays prior to compositing. This has the effect of reducing the average grade by approximately 12%, and in the opinion of Radisson and SLR is an appropriate approach to a narrow high-grade vein deposit such as O’Brien.

Compared to previous estimates, the aggregate impact on the Indicated Mineral Resources of the new drilling, the 2.2 g/t Au cut-off, and the updated capping strategy has been to add more tonnes at a lower average grade for an overall increase in contained ounces. The aggregate impact of these three factors on the Inferred Mineral Resources has been the addition of more tonnes at a higher average grade for an overall increase in contained ounces. Indicated Mineral Resources have increased by 8% to 0.63 Moz, based on an increase in tonnes of 58% to 3.49 Mt and a decrease in grade of 32% to 5.59 g/t Au. Inferred Mineral Resources have increased by 82% to 1.69 Moz, based on an increase in tonnage of 55% to 10.37 Mt and an increase in grade of 17% to 5.08 g/t Au.

O’Brien’s system of Quartz-Sulphide-Gold vein mineralization remains open to depth across a broad front beneath the historic mine workings and the updated MRE. The potential continuation of this mineralization to a 2 kilometres depth defines an Exploration Target of an additional 5 Mt to 10 Mt at grades of between 4.0 g/t and 6.0 g/t Au containing 0.6 Moz to 2.0 Moz. The potential quantity and grade of an Exploration Target is conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

A New Vision for the O’Brien Gold Project

The historic O’Brien mine produced over half a million ounces of gold at an average grade exceeding 15 g/t Au. It is clear that the former mine was ‘high-graded’, with manual mining methods applied to the highest-grade veins and ore shoots at an estimated cut-off grade of 7 g/t to 8 g/t Au. Parallel but lower-grade mineralized zones, which would be well above an economic cut-off grade today, were left unmined.

The updated MRE does not incorporate any mineral resources potentially remaining in the former mine. However, in applying the lower grade cut-off of 2.2 g/t Au based on a gold-price estimate of US$2,500, the new estimate captures the overall volume attributes of the O’Brien mineralizing system, with more tonnes and more ounces at a lower average grade. This has the benefit of improving the continuity of mineralization for future mine planning, with larger stopes and more development headings supporting a higher potential mining rate. The Project has existing mining infrastructure to support such a vision, such as a shaft in the former mine extending to a 1,000 metres depth and multiple mills in the region with significant future capacity.

Table 2 illustrates sensitivities on Indicated and Inferred Mineral Resources and the MRE block model based on cut-off grade. These are:

• a) 8.0 g/t Au (US$700/oz) representing the former mine,

• b) 4.5 g/t Au (US$1,250/oz) representing the MRE effective March 2, 2023,

• c) 2.2 g/t Au (US$2,500/oz) representing the updated MRE, and

• d) 1.5 g/t Au (US$3,800/oz) representing the recent long-term consensus price of gold.

The comparison clearly indicates the relationship between volume and grade based on cut-off, the directionality of steeply-plunging grade shoots at O’Brien, and the increased continuity of mineralization achieved at progressively lower cut-offs.

Gold Mineralization at O’Brien and Step-Out Drill Program

Gold mineralization at O’Brien occurs within quartz-sulphide veins developed primarily within the interlayered mafic volcanic rocks, conglomerates, and porphyritic andesitic sills of the Piché Group occurring in contact with the regionally significant Larder Lake-Cadillac Break (‘LLCB’). Individual veins are generally narrow, ranging from several centimetres up to several metres in thickness, and are associated with mineralized alteration envelopes of up to several metres in thickness. Multiple veins occur sub-parallel to each other, as well as sub-parallel to the Piché lithologies and the LLCB. As mapped at the historic O’Brien mine, and now replicated in the modern drilling, individual veins have well-established lateral continuity, with steeply plunging grade shoots developed over significant lengths.

Since the end of 2024, Radisson has been pursuing a program of broad step-out drilling at O’Brien with the objective of determining the overall scope of mineralization at the Project to a depth of 2 kilometres (Figure 1). The priority is the quantity and distribution of mineral resources with step-outs rather than in-filling to upgrade the classification of the existing mineral resources.

This drilling is accomplished with pilot holes followed by wedges and directional drilling to maximize drill efficiency. In October 2025, Radisson announced the expansion of the program to 140,000 metres employing an eventual eight drill rigs (see Radisson news release dated October 16, 2025). An initial 35,000 metres of the program were completed in 2025, with 72,500 metres budgeted for 2026, and a further 32,500 metres scheduled for the first half of 2027.
