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.
Vancouver, British Columbia--(Newsfile Corp. - September 4, 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 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% WO
.
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.

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).
New Advisory Role; Other Corporate
The Company is announcing that Colin Padget has resigned his position as director effective
September 1, 2025, but is being retained as an advisor to the Company going forward. The Company
wishes to thank Colin for his contributions and looks forward to his continued involvement as an advisor
to the Company.
In addition, the Company prematurely announced the grant of stock options (Options) and restricted
share units (RSUs) in its news release dated September 2, 2025. In light of the drill results in this press
release, the Company is postponing the grant to a future date.

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% WO
) 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% WO
) economically viable in wolframite deposits.
ii
For example, a
wolframite deposit with 0.4% WO
over 3 metres can be more profitable than a scheelite deposit with
0.7% WO
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% WO
.
iv
The
cut-off grade for economic viability is generally around 0.1% WO
, with highly efficient operations able to
mine at grades as low as 0.08% WO
.
v
Skarn deposits, a common deposit type, typically range from
0.34% to 1.4% WO
, with intercepts of 0.4% WO
over 1-5 metres considered very good and 0.7% WO
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% WO
and 14.1 m @ 0.58% WO
vii
at the Sangdong Mine* in South Korea and 18 m @ 1.00%
WO
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% WO
as a wolframite
deposit
ix
A result like 0.5% WO
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% WO
, 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.
