Allied Critical Metals Expands High Grade Footprint at Borralha Tungsten Project
Allied Critical Metals Expands High Grade
Footprint at Borralha Tungsten Project
New Step-Out and Infill Results Build Confidence in Resource
Growth and Model Robustness
Vancouver, British Columbia--(Newsfile Corp. - September 29, 2025) - Allied Critical Metals Inc. (CSE:
ACM) (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 report
assay results from two additional Reverse Circulation (RC) drill holes - Bo_RC_21 and Bo_RC_26 -
from its ongoing 5,000-metre campaign at the 100%-owned
Borralha Tungsten Project
in northern
Portugal.
These latest results continue to demonstrate the scale and continuity of mineralization at the Santa
Helena Breccia (SHB), with intercepts that support both lateral expansion and model refinement.
Highlights:
Bo_RC_21:
This drill hole is a west step-out at the North edge of the St. Helena Breccia that confirms
continuity of the recently discovered north-dipping lode outside the current MRE envelope, upgrading this
area to a large coherent mineralized "in section" corridor with more than 100 m width.

Drill Program Progress
To date,
3,721 metres
of RC drilling have been completed out of the planned 5,728 metres, with multiple
assay results already confirming thick mineralized zones and consistent grade distribution. The current
campaign is designed to support:
The expansion of the Mineral Resource Estimate (MRE), expected in
Q4 2025.
The development of a robust
Preliminary Economic Assessment (PEA).
The delineation of potential higher-grade corridors for future mine planning.
Roy Bonnell, CEO and Director of ACM, commented:
"With each new intercept, we are seeing our
understanding of Borralha evolve and strengthen. Bo_RC_21 confirms mineralization well beyond the
current model, while Bo_RC_26 tightens the block model in a key zone. Together, these results support
both immediate growth and long-term confidence in Borralha's development potential."

Notes:
[1] 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, true
widths are not estimated and only downhole lengths are reported. [2] True widths are unknown, to be defined after further MRE update.

Strategic Context
These results follow recently reported ultra-high-grade and extensive tungsten intercepts, including
12.0
m @ 4.27% WO
(Bo_RC_14/25), and
100.0 m @ 0.21% WO
(Bo_RC_17/25), confirming a
significant system within the Santa Helena Breccia. Allied is working systematically to define both bulk-
mineable zones and higher-grade corridors that can support future underground or hybrid extraction
scenarios.
Next Steps
Drilling is ongoing, with further results expected in the coming weeks. Step-out holes are targeting both
western and northern extensions of SHB, while infill drilling is refining the core resource model. Results
will continue to inform the MRE and subsequent economic studies.
In light of the recent new discovery of the very high grade corridor at the west dip of the central area of
the Breccia, the Company has adapted the current campaign towards confirming, and potentially
expanding upon the recent very high grade intercepts.
Sampling, QA/QC and Analytical Notes
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.
Primary disclosure remains the reported grade and interval length (and true width where known).
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.

About the Borralha Tungsten Project
Allied's Borralha Tungsten Project is one of the largest and most historically significant past-producing
tungsten operations in Western Europe. Located in northern Portugal, Borralha was once the second-
largest tungsten mine in the country and supplied strategic materials to European and Allied industries
during the 20th century, including both World Wars and the Cold War period.
Today, the project is undergoing a modern revitalization based on a combination of scale, grade,
metallurgy, and jurisdictional strength. Mineralization is dominated by coarse-grained wolframite, which
is highly desirable in global markets due to its favorable processing characteristics and higher
recoveries compared to scheelite-bearing deposits.
Borralha benefits from existing infrastructure, shallow mineralization, and a simple processing route,
making it one of the most advanced tungsten development projects in the European Union. These
attributes are particularly important in the context of the EU Critical Raw Materials Act (2024/1252) and
NATO strategic autonomy initiatives, both of which explicitly identify tungsten as a defense-critical raw
material subject to severe supply risk.
With the EU currently dependent on over 80% of its tungsten imports from China, Borralha represents a
rare and strategic opportunity to develop a secure, domestic, and NATO-aligned supply source. As
Allied continues to advance drilling, resource expansion, and economic studies, Borralha is poised to
play a central role in reshaping Europe's tungsten landscape-supporting both decarbonization
technologies and defense-industrial resilience.
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 but is typically
more costly and complex to process, requiring flotation methods with higher capital and operating
expenditures and lower recoveries.
i
In contrast, wolframite can be processed more efficiently using
gravity and magnetic separation, resulting in lower costs and higher recoveries, making lower grades
economically viable in wolframite deposits. For example, a lower grade wolframite deposit can be more
attractive than a slightly higher grade scheelite deposit.
ii
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.
iii
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. 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 wolframite tungsten mineralization and secure location position it as a strategic and
responsible tungsten exploration company, well placed to take advantage of a rising-demand market.
