Vancouver, British Columbia--(Newsfile Corp. - September 23, 2025) - Allied Critical Metals Inc. (CSE: ACM,OTC:ACMIF) (OTCQB: ACMIF) (FSE: 0VJ0) ("Allied" or the "Company"), which is focused on its 100% owned past producing Borralha and Vila Verde tungsten projects in northern Portugal, is pleased to announce highlights from its 2023 & 2024 drill program on its 100% owned Borralha Tungsten Project. Although the drill results were included in its current technical report on the Borralha Tungsten Project (the "Borralha Technical Report"), the individual drill results were never individually showcased. The Borralha Technical Report is entitled, "Technical Report on the Borralha Property, Parish of Salto, District of Vila Real, Portugal', dated effective July 31, 2024" which is available under the Company's profile on SEDAR+ at www.sedarplus.ca.

During Allied's 2023-2024 Borralha drill program, more than 3,685 meters were drilled in 16 drill holes in the Santa Helena Breccia, as described in the Borralha Technical Report, which includes the following notable intercept highlights in the table below.

Table 1: Highlights of Intercepts from 2023-24 Borralha Drill Program

*Reported intervals are downhole lengths. Estimated true widths were calculated from hole orientation and the interpreted geometry of the mineralized corridors. Estimates may vary locally where geometry changes. Where intervals fall outside the resource block-model domains, the true width is not known and only the downhole length is reported.

Table 2: Drill Hole Collar Locations

The Company has continued its exploration of the Santa Helena Breccia with its 2025 drill program which is also focused on the Santa Helena Breccia (SHB) of Borralha.

"The company invested approximately $4.1 million in 2023 & 2024 on exploration to further give confidence to investors prior to its public listing," Roy Bonnell, CEO & Director, Allied Critical Metals, stated. "We are now working to provide an updated version of the Mineral Resource Report for Borralha in Q4 2025, which is expected to include more than approximately 5,700 metres of drill results from this year's program."

Allied's flagship Borralha Tungsten Project, strategically located in northern Portugal, represents one of the most significant undeveloped tungsten deposits in the western world having a potential near-term source of supply outside of the domain of China and Russia. With the NI 43-101 mineral resource estimate of 4.98 Mt @ 0.22% WO₃ (Indicated) and 7.01 Mt @ 0.20% WO₃ (Inferred) previously reported in the Borralha Technical Report, Borralha has the potential to provide a stable and scalable source of tungsten concentrate to Western markets. On September 4, 2025, Allied announced a drill intercept of 12.0 metres @ 4.27% WO₃ including 6.0 metres @ 8.39% WO₃ from 252.00 metres downhole, confirming one of the highest-grade tungsten intercepts reported in Western exploration, especially for high quality wolframite tungsten mineralization.

Technical Information and Quality Assurance/Quality Control (QA/QC)

During the 2023-24 drilling campaign three PQ-size diamond drill holes and thirteen reverse circulation boreholes, totalling 3,685.40 metres of drilling, were completed to their proposed lengths. Minerália was contracted to supervise and manage the drilling program that included three PQ-size diamond drill holes, namely Bo_Met_01, _02 and _ 02a, totalling 490.4 metres of drilling and thirteen reverse circulation drill holes, namely Bo_RC_01 to _13 that totalled 3,195.0 metres of drilling. Diamond drill hole Bo_Met_02 intersected old underground workings and was abandoned and re-drilled nearby as Bo_Met_02a. As of the effective date of this report, the Company has drill tested the SHB with 5,602.95 metres of drilling, infilling historical drill holes and extending exploration towards the southern part of the SHB.

The cores from the two diamond holes, Bo_Met_01 and _ 02a were halved length wise after logging and one-half of the cores were shipped to Wardell Armstrong International Ltd. with offices in Truro, London for metallurgical test work. The other half of drill core was sampled and shipped to the ALS preparatory laboratories in Seville, Spain and later to the ALS certified assay laboratories in Dublin Road, Loughrea, Co., Ireland for multi-element ICP analyses. The later 1-metre reverse circulation drill cuttings were composited into 2-metre samples and direct shipped to the ALS preparatory laboratories in Seville, Spain and later to the ALS certified assay laboratories in Dublin Road, Loughrea, Co., Ireland.

The analytical samples were collected directly from the rig splitter according to a sampling list that documented the metres and sampling sequence for each drill hole. This list also identified which sample should be collected in duplicate as well as which certified reference material ('CRM') were to be placed in the numerical sequence. The CRMs were randomly inserted at every 20 samples (5%), and duplicate samples were collected every 20 samples (5%). Thus, there's an alternating CRM and Duplicate every 10th sample.

The analytical and reject samples are then transported in boxes from the drilling site to the core shed by a designated employee. The analytical samples were stored on labelled palettes for later direct shipping to the ALS preparation laboratories in Seville, Spain. Later, the pulp and reject samples were securely stored in the logging room on the property.

RC samples were prepared by ALS preparation laboratory in Seville, Spain, crushing the sample with up to 70% of the material passing a 2 mm screen, and then each sample was split to 250 g and pulverized with hardened steel to 85% passing a 75 μm screen. Each resultant sub-sample was then direct shipped to their certified assay laboratory Dublin Road, Loughrea, Co., Ireland.

The samples are analyzed by the ME-MS81 ALS method that applies a lithium borate fusion to the sample and the result of this fusion is measured by applying an ICP-MS. It is also applied to the ALS ME-4ACD81 procedure which reports base metals by a 4-acid digestion and later analyzed by an ICP-MS procedure. Any over-limit tungsten values were re-analysed at the same laboratory by a W-XRF15b procedure that uses a lithium borate fusion with an XRF analysis. The analytical results were then securely emailed to the company.

To the best of the Company's knowledge, no drilling, sampling, recovery, or other factors have been identified that would materially affect the accuracy or reliability of the data referenced herein. As indicated further above, these drilling results and related procedures and technical information were also detailed by an independent qualified person in the Borralha Technical Report which is available under the Company's profile on SEDAR+ at www.sedarplus.ca.

Understanding Tungsten

To understand tungsten, it is critical to understand the difference between wolframite tungsten mineralization and scheelite tungsten mineralization. Scheelite often reports higher grades (0.3%-1.0% WO₃) but is more costly and complex to process, requiring flotation methods with higher capital and operating expenditures and lower recoveries.ⁱ In contrast, wolframite, which is the focus of Allied, can be processed more efficiently using gravity and magnetic separation, resulting in lower costs and higher recoveries, making lower grades (~0.15%-0.25% WO₃) economically viable in wolframite deposits. For example, a wolframite deposit with 0.4% WO₃ over 3 metres can be more profitable than a scheelite deposit with 0.7% WO₃ over the same interval due to lower processing costs and higher recovery rates.ⁱⁱ

In Western exploration drilling, tungsten grades typically range from 0.3% to 1.0% WO₃.ⁱⁱⁱ The cut-off grade for economic viability is generally around 0.1% WO₃, with highly efficient operations able to mine at grades as low as 0.08% WO₃. Skarn deposits, a common deposit type, typically range from 0.34% to 1.4% WO₃, with intercepts of 0.4% WO₃ over 1-5 metres considered very good and 0.7% WO₃ over 1-3 metres considered very high-grade.^iv Intercept lengths can range from 0.6 metres to over 100 metres, with longer intercepts at strong grades generally preferred for economic mining. A result like 0.5% WO₃ over 3 metres is generally considered strong within Western tungsten exploration benchmarks, especially for wolframite tungsten mineralization.^v

It is also important to recognize that China, Russia, and North Korea control approximately 87% of the world's tungsten supply, using cheap labor and minimal environmental standards in authoritarian regimes. ^vi As a result, production costs and grades in these countries are not comparable to Western projects, which operate under higher labor, ESG, and energy cost structures. Evaluating projects outside these regions provides a realistic benchmark for what grades and intercepts are economically viable while supporting secure, NATO-aligned supply chains.

For Allied, this context is significant. Wolframite tungsten grades, ranging from 0.2% to 1.0% WO₃ are strong global wolframite benchmark values. The Company's focus on wolframite ensures lower processing costs and higher recoveries, supporting project economics even at lower grades. Allied's operations in secure jurisdictions align with Western critical mineral needs, avoiding geopolitical risks associated with China and Russia while positioning the Company to benefit from growing tungsten demand across defense, aerospace, and electrification sectors. Allied's strong grades, low-cost processing advantages, and secure location position it as a strategic and responsible tungsten exploration company, well placed to support robust project economics in a rising-demand market. ^vii

    New northern deep lode opens a new northern vector for resource growth.

Allied Critical Metals Inc. (CSE: ACM,OTC:ACMIF) (OTCQB: ACMIF) (FSE: 0VJ0) ("Allied" or the "Company"), which is focused on its 100% owned past producing Borralha and Vila Verde tungsten projects in northern Portugal, is pleased to announce additional significant assay results from its ongoing 4,200 metres reverse circulation (RC) drilling campaign at its Borralha Tungsten Project. The latest results from drill holes Bo_RC_1525, Bo_RC_1725, and Bo_RC_2225 extend mineralization both west and north of the previously announced Bo_RC_1425 high-grade intercept, reinforcing that the Santa Helena Breccia within the Borralha Project is emerging as a larger and higher-grade orebody than previously modeled. The Company will commence an additional fully funded 1,528 metre drilling in the fourth quarter of 2025 to build off the drilling success in July.

The results are especially timely as tungsten price has now reached a new high of U.S.$550/MTU, which is an increase of more than 40% over the past four months as demand for the critical mineral increases in the face of further supply chain restrictions from non-Western countries [Source: FastMarkets].

Roy Bonnell, CEO & Director of Allied, commented: "These thick, continuous intervals in the central-south and the new northern deep lode materially expand the working envelope at the Santa Helena Breccia in Borralha. Together with the previously reported ultra-high-grade intercept in Bo_RC_14/25, we see clear evidence of a system that is both bigger and better than we initially assumed. This is exactly the kind of data we want feeding into the upcoming Mineral Resource Estimate (MRE) and Preliminary Economic Assessment (PEA). Moreover, the results demonstrate the potential of Borralha as a key strategic, safe, and secure source of tungsten for Portugal, the EU and NATO."

João Barros, President & COO of Allied, stated: "Tungsten is recognized by the European Union as both a critical and strategic raw material under the CRMA. With Europe producing less than 3% of its annual needs and facing increasing Chinese export restrictions, the Borralha Project represents a vital opportunity to strengthen secure, Western-aligned supply chains. Our work directly supports the EU target of sourcing at least 10% of its critical raw materials domestically by 2030, while reinforcing Portugal's role as a key contributor to Europe's strategic independence. "

General (Ret.) James A. "Spider" Marks, Director of the Company's U.S. subsidiary, stated: "Expanding the mineral resource at the Borralha Project is an essential next step in path to fulfilling the immense need in Portugal, the EU, NATO and the United States for tungsten powders, concentrates and other byproducts. The U.S. and NATO defense military complexes are dependent on tungsten. Without domestic supply of tungsten, the Borralha Project becomes a very important piece to the critical mineral supply chains for the United States and NATO."

These latest drilling results are highly significant because they combine both scale and grade. The long intercepts at 0.21-0.33% WO₃ in Bo_RC_17/25 are particularly meaningful in wolframite systems. In addition, the drilling program is clearly growing the footprint of the Breccia complex. The Bo_RC_22/25 delineates a northern deep lode, while Bo_RC_15/25 ties the west-deep high-grade corridor back to the main body-both lines of evidence supporting a larger Santa Helena Breccia, the principal mineralized body at Borralha Project.

Geologic Interpretation

The geologic interpretation indicates that the Santa Helena Breccia is expanding: the combination of broad medium-grade intervals and discrete high-grade intercepts points to a larger, better-connected breccia body than previously modeled. Priority vectors for follow-up include the west-dip high-grade trend (Bo_RC_14/25 and Bo_RC_15/25) and the northern wider deep lode (Bo_RC_22/25), which will guide near-term drilling and feed the Q4 2025 MRE and subsequent PEA workstreams.

Next steps

Ongoing drilling continues to target west-deep and northern extensions while tightening spacing across the MRE backbone. Additional assays from completed holes will be released as received and validated. The program remains aligned with the timeline toward an updated MRE (Q4 2025) and PEA thereafter.

Technical Information and Quality Assurance/Quality Control (QA/QC)

Drilling was completed using reverse-circulation (RC). All sample bags were pre-labelled with a unique internal sequence number used consistently for the assay sample and corresponding reject. Sampling was conducted on 2.0 m intervals for analytics. For each 2.0 m interval, two 1.0 m reject samples were also collected as representative splits. Splitting was performed at the rig via a rotary splitter integral to the RC cyclone.

Sampling followed pre-prepared sample lists that recorded downhole metreage, sequence, and the placement of Certified Reference Materials (CRMs) and field duplicates. CRMs were inserted at a rate of 1 in 20 samples (5%) and field duplicates at 1 in 20 samples (5%), arranged so that every 10th sample alternated between a CRM and a duplicate.

Analytical and reject samples were boxed at the drill site and transported by company personnel to the project core/logging facility. Analytical samples were stored on labelled pallets pending direct shipment to ALS's preparation laboratory in Seville, Spain. Pulps and rejects were subsequently stored securely in the project logging room.

At ALS Seville, samples were crushed to 70% passing 2 mm, riffle-split to ~250 g, and pulverized using hardened steel to 85% passing 75 μm. Pulps were shipped to ALS Loughrea (Ireland) for analysis. The primary analytical method was ME-MS81 (lithium borate fusion with ICP-MS finish). Base metals were also reported using ME-4ACD81 (four-acid digestion with ICP-MS finish). Over-limit tungsten results were re-assayed using W-XRF15b (lithium borate fusion with XRF). Analytical results were delivered directly by ALS to the Company via secure electronic transfer.

To the best of the Company's knowledge, no drilling, sampling, recovery, or other factors have been identified that would materially affect the accuracy or reliability of the data referenced herein.

Where reported, metal factor (m·%WO₃) is the product of interval length and grade and is provided as supplemental context only. Primary disclosure remains the reported grade and interval length (and true width where known).

Allied Critical Metals Inc. (CSE: ACM,OTC:ACMIF) (OTCQB: ACMIF) (FSE: 0VJ0) ("Allied" or the "Company"), which is focused on its 100% owned past producing Borralha and Vila Verde tungsten projects in northern Portugal, is pleased to announce its upcoming fall 2025 marketing and investor engagement schedule, which includes international conferences and on-site investor tours of Borralha and Vila Verde, its two high grade tungsten projects located in northern Portugal.

General (Ret.) James A. "Spider" Marks, director of the Company's U.S. subsidiary stated, "I am eager to see Allied continue to raise its profile and connect with its new and existing investors to help expedite Allied's business plan while securing a stable safe supply chain of tungsten for western countries. This is especially critical during this time of ever-increasing threats showcased in China's recent military parade and meeting of the leaders of China, Russia and North Korea. Now more than ever, western nations need to work together to secure stable supply chains of critical minerals such as tungsten."

Highlights:

• Drill hole Bo_RC_14/25 intersects 12.0 metres @ 4.27% WO₃ including 6.0 metres @ 8.39% WO₃ from 252.00 metres downhole, confirming one of the highest-grade tungsten intercepts reported in Western exploration, especially for high quality wolframite tungsten mineralization. This validates early visual observations and supports the presence of a controlled high-grade breccia corridor.

• Over 2,500 metres of drilling completed across nine holes, with multiple intercepts of visible wolframite and chalcopyrite. The remaining 1,600 metres of the 4,200 metre campaign now underway with a further fully funded 1,528 metres now also planned with two rigs active on site.

• Tungsten price reaches high of $545 USD/MTU, up approximately 40% in last 4 months as demand for the critical mineral increases with further supply chain restrictions from non-Western countries.

Allied Critical Metals Inc. (CSE: ACM,OTC:ACMIF) (OTCQB: ACMIF) (FSE: 0VJ0) ("Allied" or the "Company"), which is focused on its 100% owned past producing Borralha and Vila Verde tungsten projects in northern Portugal, is pleased to announce an update on its ongoing 4,200-metre Reverse Circulation (RC) drill program at the Borralha Tungsten Project. The initial phase of the campaign was launched in early June 2025 and continues to deliver strong technical progress, supporting: (i) an updated Mineral Resource Estimate (MRE), anticipated in Q4 2025; (ii) advanced metallurgical testing; and (iii) the Company's Preliminary Economic Assessment (PEA) for a large scale processing facility located at Borralha, targeted for completion later this year. A further fully funded 1,528 metre drilling is now also planned for the fourth quarter of 2025 to build off of the successes in July.

High-grade results from drill hole Bo_RC_14/25 marks a breakthrough for the Borralha Project, with further drilling and a Preliminary Economic Assessment already underway. The results are particularly timely as tungsten price has reached a new high of $545 USD/MTU, which is an increase of approximately 40% over the past four months as demand for the critical mineral increases in the face of further supply chain restrictions from non-Western countries [Source: FastMarkets].

Roy Bonnell, CEO & Director of Allied, commented, "These initial assay results are a major step forward for the Borralha Project and a clear validation of our geological model. The exceptional tungsten grades intersected in Bo_RC_14/25 place Borralha among the most exciting undeveloped critical mineral assets in Europe. As we advance toward the Mineral Resource update and Preliminary Economic Assessment, these results strengthen our confidence in Borralha's potential to become a cornerstone of Western countries' strategic raw material supply."

As of July 30, 2025, Allied had completed approximately 2,500 metres of drilling across nine drill holes. Drilling operations were temporarily paused during August in compliance with seasonal fire safety restrictions and successfully resumed on September 1, 2025. The program continues to advance towards its objectives, with a clear focus on three key technical priorities:

• Expanding and upgrading the existing tungsten resource in accordance with National Instrument 43-101-Standards of Disclosure for Mineral Projects ("NI 43-101"), with emphasis on increasing tonnage and converting Inferred Resources to Indicated Resources classification; and

• Collecting representative material for metallurgical testing, to validate marketable concentrate grades at 65% WO₃.

Overview of Drilling to Date:

• Drill hole Bo_RC_14/25 confirmed the presence of high-grade tungsten mineralization, with visual observations of massive wolframite supporting the interpretation of a potentially enriched corridor within the breccia-hosted system.

• Drill hole Bo_RC_15/25 aimed to access the west deep step-out potential at the south area of the breccia. Visual inspection confirmed the presence of breccia together with evidence of wolframite. Assays of this drill hole are ongoing.

• Drill holes Bo_RC_16/25 and Bo_RC_17/25 are infill drillholes to increase the Resource resolution and knowledge of the interchange between the large bulkable medium grade central backbone of the south area of the breccia, into the medium size high-grade corridors deeper to west. As expected, breccia with visible mineralization was visible, and the pending assays results will provide proper interpretation.

• Drill holes Bo_RC_18/25 , Bo_RC_19/25 and Bo_RC_26/25 are infill drillholes at the central and lower grade area of the Breccia. Here the goal was to improve the Resource model resolution and grade at this section. Some visible mineralization was identified, but the pending assays are necessary to confirm the potential upgrade.

• Drill holes Bo_RC_21/25 and Bo_RC_22/25 are drillholes meant to step-out the previous discovery of a potential new high-grade large corridor at the Bo_RC_11/24 drill hole that has no resources due to lack of composites pairs. Both drillholes encountered continuous breccia and multiple zones with visible sulphides and polymetallic indicators, including wolframite and chalcopyrite, reinforcing the continuity and depth of the mineralized system. Pending assays will confirm if a new economical vector for considerable Resource expansion is present at the north deep area of the breccia.

All samples from the nine completed drill holes have been dispatched to ALS Laboratories in Seville for geochemical analysis, with initial assay results now beginning to return. The first results received from hole Bo_RC_14/25 confirm the presence of tungsten mineralization, consistent with earlier visual observations. Additional assay results from the remaining holes are expected over the coming weeks.

Building on Visual Confidence with Excellent Drill Results

The early stages of the 2025 RC drill campaign at Borralha Project were marked by highly encouraging visual intercepts across several holes. With the arrival of the first assays, that confidence has now been materially validated. Initial data confirms not only the continuity of breccia-hosted mineralization but also suggests that the Borralha Project hosts very high-grade tungsten intercepts as described below.

The results from the Bo_RC_14/25 drill hole represents a major technical milestone for Allied. The grade and length of the intercept reinforce the Company's position that the Borralha Project is one of Europe's most strategically important undeveloped tungsten assets. These assays will feed directly into the upcoming Mineral Resource Estimate (MRE) and Pre-Economic Assessment (PEA), both of which are expected to underpin Allied's near-term development plans.

Assay Highlights from Bo_RC_14/25 include, from 252.00m downhole:

• 12.0 m @ 4.27% WO₃*, including

• 6.0 m @ 8.39% WO₃*

*WO₃ Tungsten trioxide % converted from W ppm multiplied by 1.2611 stoichiometric factor. W ppm results are from ALS Laboratories analytical method ME-MS81. For the ME-MS81 above detection limit of >10,000 ppm assays, ME-XRF15c is used.

A geological cross section for hole Bo_RC_14/25 is presented below, illustrating the location of the high-grade intercept within the broader breccia-hosted mineralized zone. The section highlights the continuity of the tungsten-bearing structures, the correlation with visual observations, and the potential for further extensions at depth and along strike.

Technical Information and Quality Control / Quality Assurance

Drillholes were all conducted with RC diamond bit drilling. All sample bags were pre-marked prior to drilling. They were each identified with an internal sequence number used as a sample identifier, both the sample for analysis and its reject samples. Each analytical sample bag is filled with a portion of 2 m length of drilled rock and each reject sample bag will take another representative portion of 1 m length of drilled rock. Thus, each two reject samples will be the equivalent to one assay sample. The splitting is done as part of the drilling process using a rotary splitter.

The analytical samples were collected directly from the rig splitter according to a sampling list that documented the metres and sampling sequence for each drill hole. This list also identified which sample should be collected in duplicate as well as which certified reference material ('CRM') were to be placed in the numerical sequence. The CRMs were randomly inserted at every 20 samples (5%), and duplicate samples were collected every 20 samples (5%). Thus, there's an alternating CRM and Duplicate every 10th sample.

The analytical and reject samples are then transported in boxes from the drilling site to the core shed by a designated employee. The analytical samples were stored on labelled palettes for later direct shipping to the ALS preparation laboratories in Seville, Spain. Later, the pulp and reject samples were securely stored in the logging room on the property.

To the best of the Company's knowledge, no drilling, sampling, recovery, or other factors exist that would materially compromise the accuracy or reliability of the referenced data

RC samples were prepared by ALS preparation laboratory in Seville, Spain, crushing the sample with up to 70% of the material passing a 2 mm screen, and then each sample was split to 250 g and pulverized with hardened steel to 85% passing a 75 μm screen. Each resultant sub-sample was then direct shipped to their certified assay laboratory Dublin Road, Loughrea, Co., Ireland.

The samples are analyzed by the ME-MS81 ALS method that applies a lithium borate fusion to the sample and the result of this fusion is measured by applying an ICP-MS. It is also applied to the ALS ME-4ACD81 procedure which reports base metals by a 4-acid digestion and later analyzed by an ICP-MS procedure. Any over-limit tungsten values were re-analysed at the same laboratory by a W-XRF15b procedure that uses a lithium borate fusion with an XRF analysis. The analytical results were then securely emailed to the Company.

Project Momentum and Strategic Positioning

The drill program is a cornerstone of Allied's strategy to position Borralha as Europe's leading high-grade tungsten development, combining grade, scale, and near-term production potential in a secure EU jurisdiction. With tungsten designated as a Critical and Strategic Raw Material by both the European Union and the United States, Borralha directly addresses Western supply vulnerabilities at a time of rising global demand and constrained Chinese exports. As one of the only advanced-stage tungsten assets in Western Europe, Borralha is uniquely placed to support defense readiness, AI, EVs, and the EU's Critical Raw Materials Act objectives for domestic sourcing.

This campaign also supports Allied's permitting and development milestones, including the submission of additional technical information in response to follow-up questions from the Environmental Impact Assessment (EIA) evaluation committee–a standard step in the review process. The Company expects to deliver its formal response by third quarter of 2025, with a final decision anticipated in fourth quarter of 2025 or early first quarter of 2026.

Next Steps

Allied is now preparing to complete the final 1,600 metres of drilling to reach the planned total of 4,200 metres for the current Phase 1 campaign. The remaining holes, including Bo_RC_20/25, Bo_RC_23/25, and Bo_RC_24/25 and Bo_RC_25/25, have been selected based on strong visual intercepts, structural continuity, and geological insights from previously completed drilling. Minor adjustments to the drill plan are being implemented to maximize coverage of key mineralized corridors while maintaining program efficiency. In addition, a further 1,528 metres drilling is now also planned for the fourth quarter of 2025 to build off of the successes in July.

Following a scheduled pause in August due to the regional fire season, drilling resumed on September 1 with two rigs operating simultaneously. The campaign has quickly regained momentum and remains on track to complete the targeted meterage within the planned timeframe. Field operations continue to run efficiently, positioning Allied to generate the technical data required for the upcoming Mineral Resource Estimate (MRE) update and Preliminary Economic Assessment (PEA).

About Tungsten

It is critical to understand the difference between wolframite mineralization of tungsten and scheelite mineralization of tungsten. Scheelite often reports higher grades (0.3%-1.0% WO₃) but is more costly and complex to process, requiring flotation methods with higher capital and operating expenditures and lower recoveries.ⁱ In contrast, wolframite, which is the focus of Allied Critical Metals can be processed more efficiently using gravity and magnetic separation, resulting in lower costs and higher recoveries, making lower grades (~0.15%-0.25% WO₃) economically viable in wolframite deposits.ⁱⁱ For example, a wolframite deposit with 0.4% WO₃ over 3 metres can be more profitable than a scheelite deposit with 0.7% WO₃ over the same interval due to lower processing costs and higher recovery rates.ⁱⁱⁱ

In Western exploration drilling, scheelite tungsten grades typically range from 0.3% to 1.0% WO₃.^iv The cut-off grade for economic viability is generally around 0.1% WO₃, with highly efficient operations able to mine at grades as low as 0.08% WO₃.^v Skarn deposits, a common deposit type, typically range from 0.34% to 1.4% WO₃, with intercepts of 0.4% WO₃ over 1-5 metres considered very good and 0.7% WO₃ over 1-3 metres considered very high-grade.^vi Intercept lengths can range from 0.6 metres to over 100 metres, with longer intercepts at strong grades generally preferred for economic mining. For example, two leading western tungsten mines demonstrate the standards for scheelite with results like 9.5 m @ 0.76% WO₃ and 14.1 m @ 0.58% WO₃^vii at the Sangdong Mine* in South Korea and 18 m @ 1.00% WO₃ reported at the Mt. Carbine Tungsten Project* in Australia.^viii

In contrast, the Panasqueira Mine* in Portugal typically reports 1-5 m @ 0.25-0.5% WO₃ as a wolframite deposit^ix A result like 0.5% WO₃ over 3 metres is considered typical and strong within Western tungsten exploration standards, especially for wolframite tungsten mineralization.^x

To understand tungsten, it is also important to recognize that China, Russia, and North Korea control approximately 87% of the world's tungsten supply, using cheap labour and minimal environmental standards in authoritarian regimes.^xi As a result, production costs and grades in these countries are not comparable to Western projects, which operate under higher labour, ESG, and energy cost structures.^xii Evaluating projects outside these regions provides a realistic benchmark for what grades and intercepts are economically viable while supporting secure, NATO-aligned supply chains.^xiii

For Allied, this context is significant, as the Company's grades, ranging from 0.2% to 1.0% WO₃, are considerable against global wolframite benchmarks, with intercepts that meet or exceed typical Western results.^xiv The Company's focus on wolframite will correspond to lower processing costs and higher recoveries, supporting project economics even at lower grades.^xv Allied's operations in secure jurisdictions align with Western critical mineral needs, avoiding geopolitical risks associated with China and Russia while positioning the Company to benefit from growing tungsten demand across defense, aerospace, and electrification sectors.^xvi Allied's strong grades, low-cost processing advantages, and secure location position it as a strategic and responsible tungsten exploration company, well placed to support robust project economics in a rising-demand market.^xvii
