Western Australian Titanium Project Confirmed As World's Largest

Upgraded 8.2Bt Mineral Resource includes first Measured Resource and almost 4Bt in higher-confidence categories

Highlights

• World's largest publicly reported titanium resource: 8.16Bt at 4.3% TiO₂ for 349Mt of contained TiO₂ across the Thomas and Cosgrove deposits.
• First Measured Resource: 374Mt at 5.8% TiO₂ for 21.6Mt of contained TiO₂.
• Almost half the global resource is now higher confidence: Measured and Indicated Resources total 3.96Bt, or approximately 49% of the MRE.
• Near-surface development opportunity: the weathered zone contains 4.39Bt at 4.4% TiO₂. The material occurs from surface, with minimal overburden and no interburden, and will be a focus of future mine planning.
• High-grade zones: continuous zones averaging more than 6% TiO₂ extend over 5km of strike and up to 1.25km width at Thomas, and over 4km of strike at Cosgrove.
• Empire's ASX dual listing remains on track for H2 CY2026, with Canaccord Genuity (Australia) acting as lead adviser.

AIM-listed Empire Metals Limited (AIM: EEE; OTCQX: EPMLF) (Empire or the Company), which is progressing towards an ASX dual listing in H2 CY2026, has confirmed its Pitfield Project in Western Australia as the world's largest publicly reported titanium resource following a major upgrade to its JORC 2012 Mineral Resource Estimate.

The global Mineral Resource now stands at 8.16 billion tonnes at 4.3% TiO₂, containing 349 million tonnes of TiO₂. The upgrade includes Pitfield's first Measured Resource and lifts Measured and Indicated Resources to almost four billion tonnes, providing a stronger platform for mine planning and economic studies.

The MRE covers the Thomas and Cosgrove deposits and is reported on a 100% project basis. Empire holds a 70% interest in Pitfield and is manager and sole operator of the project joint venture.

Titanium is included on Australia's Critical Minerals List and is used across paints, advanced manufacturing, aerospace, defence and medical applications. Pitfield's scale, Western Australian location and demonstrated processing pathway position it as a potentially important new source of titanium products.

Commenting on the MRE upgrade, Empire Managing Director Shaun Bunn said:

"Western Australia now hosts the world's largest publicly reported titanium resource. This upgrade moves Pitfield beyond an exploration story, with our first Measured Resource providing the confidence needed to advance mine planning, processing and economic studies.

"The scale is clearly important, but the quality of the upgrade is equally significant. Almost four billion tonnes is now in the Measured and Indicated categories, while the high-grade weathered material begins at surface and remains central to the way we are approaching development.

"We have also demonstrated a processing route capable of producing high-purity titanium dioxide. Our work now turns to converting more of the resource to Measured, refining the flowsheet and completing the technical and economic studies needed to define a commercially robust development pathway. With our planned ASX dual listing also progressing, we believe this is an important time for Empire as we advance a globally significant titanium resource in Western Australia."

What the upgrade means for Pitfield

The upgraded MRE materially increases confidence in the scale and continuity of the titanium mineralisation at Pitfield. The first Measured Resource has been defined within the high-grade Thomas deposit, while a further 3.6Bt is classified as Indicated across Thomas and Cosgrove. This provides a substantially larger higher-confidence resource base from which Empire can undertake mine planning and economic studies.

The resource comprises near-surface weathered material as well as underlying fresh mineralisation. Within the weathered zone, the host rocks have been altered to soft, friable material containing naturally formed anatase and rutile. This zone extends from surface to an average depth of approximately 30m to 50m and has minimal overburden and no interburden.

High-grade zones averaging more than 6% TiO₂ extend over 5km of strike and up to 1.25km width at Thomas, and over 4km of strike at Cosgrove. These zones will help Empire assess the location and sequencing of potential early mining areas as project studies progress.

Empire has also demonstrated an integrated flowsheet based on conventional processing steps capable of producing high-purity, more than 99% TiO₂ targeting pigment and titanium sponge feedstocks.

Why titanium matters

Titanium is included on Australia's Critical Minerals List. Titanium dioxide is widely used in pigments, plastics, coatings and paper works while titanium metal is valued for its strength, low weight and resistance to corrosion across aerospace, defence, medical and advanced manufacturing applications. Pitfield's scale, location and demonstrated processing pathway give it the potential to become a significant new source of titanium products from Western Australia.

Pitfield is located near Three Springs in Western Australia's Mid-West, with access to established road, rail, power and port infrastructure.

Next steps

Empire is reviewing the updated resource model to design the next phase of drilling at Thomas and Cosgrove. The program will focus on converting additional Indicated Resources to Measured and generating the information required for mine planning and economic assessment.

Work will also include bulk sampling, further flowsheet optimisation and ongoing product development. The Company is targeting a further MRE upgrade in mid-2027 as it progresses the studies required to support a future Ore Reserve assessment.
