Alien Metals Limited (AIM: UFO), a minerals exploration and development company, is pleased to provide an update on its Pilbara iron ore portfolio following the completion of an independent technical review by ERM Australia Consultants Pty Ltd (“ERM”).
The ERM review comprised a high-level prospectivity and exploration targeting assessment and did not include the preparation or estimation of Mineral Resources or Ore Reserves. The review assessed prospectivity and prioritised next-stage work programs across the Company’s Pilbara iron projects, including the West Pilbara Vivash Gorge and Brockman projects, and the East Pilbara Hancock Project area.
Highlights
· Independent review completed: ERM has completed a prospectivity assessment of Alien’s Pilbara iron ore portfolio and recommended a prioritised and staged approach to follow-up work.
· Assessment confirms significant potential for Brockman Iron Formation mineralisation potential across the Vivash and Brockman Projects.
· Vivash and Brockman Projects remain underexplored and drill untested, presenting exploration potential.
· Vivash tenure directly adjoins Fortescue Metals Group Ltd’s Vivash Southwest Mineral Project which has a JORC Mineral Resource of 28Mt @ 58.8% Fe.
· Brockman Project is located adjacent to BHP Deposit 20 and along strike to the FMG Farquhar East and API JV[1] Paracelsus deposits, highlighting a favourable geological setting

Independent Review Highlights Geological Prospectivity
Alien is pleased to announce that an independent expert re-evaluation by ERM has reinforced the strong iron ore credentials of its West Pilbara portfolio.
The review confirms that the Company’s projects are strategically positioned within proven, iron-rich stratigraphy of the Hamersley Basin, with geological characteristics consistent with economic mineralisation hosted in the Brockman Iron Formation.
The assessment identified untested strike positions considered prospective for further exploration activities across multiple tenements.
Vivash Project (E47/3071) – Strategic Neighbour to Established Resource
The Vivash Project remains highly prospective for:
· Bedded Iron Deposit (BID) mineralisation within the Brockman Iron Formation (primary target).
· Secondary potential within the Marra Mamba Iron Formation.
· Untested exploration potential for Channel Iron Deposit (CID) and Detrital Iron Deposit (DID) mineralisation.
The strategic significance of Vivash is underscored by its proximity to FMG’s Vivash Southwest Mineral Resource:
· 28Mt @ 58.8% Fe
· 6.02% SiO₂ | 2.80% Al₂O₃ | 0.135% P | 6.6% LOI
The geological continuity materially strengthens the exploration thesis and reinforces the potential for extensions of iron mineralisation onto Alien’s ground.

Brockman Project (E47/3953) – Adjacent to BHP Deposit 20
The Brockman Project is considered prospective for:
· Detrital hosted iron mineralisation
· Potential mineralisation within the Dales Gorge Member of the Brockman Iron Formation, identified immediately south at BHP Deposit 20.
· CID mineralisation within southwest valley systems.
The proximity along strike to the FMG Farquhar East and APIJV Paracelsus iron ore deposits provides strong regional geological validation and enhances the discovery potential across the tenure.

Hancock Project – Strike Lengths Untested
Residual iron mineralisation potential remains within the Weeli Wolli and Boolgeeda Iron Formations, with significant strike lengths yet to be systematically explored.
These formations represent additional upside the previously reported Hancock Project Mineral Resources over the Ridge C, Ridge E and Sirius deposits.
Forward Work Program – Field Activation in Q2
Alien will mobilise in Q2 2026 with a targeted, iron-focused field program designed to unlock this potential.
Planned activities include:
· Helicopter-supported geological reconnaissance across Vivash and Brockman, targeting outcropping Brockman Iron Formation to identify surface enrichment.
· Assessment of CID potential across northeastern tenement areas.
· Field delineation of unexplored Weeli Wolli Formation iron ridges at Hancock.
· Geological cross-sectional review of Hancock Ridge E & C and Sirius-grade resource models to determine whether there is potential for extensions or reinterpretation within and adjacent to the historical Mineral Resource extents.
Positioned for Discovery and Value Creation
The ERM review supports continued exploration of Alien’s West Pilbara iron ore portfolio sits within a proven iron province, adjacent to major operators, and hosts multiple mineralisation styles across largely underexplored ground.
With field programs commencing in Q2 2026, the Company is advancing a clear pathway to unlock exploration value and position the portfolio for potential resource growth.
