MRE Upgrade Confirms Pitfield Project as the World's Largest Titanium Resource

LONDON, UK / ACCESS Newswire / August 19, 2026 / Empire Metals Limited, the AIM-quoted and OTCQX-traded exploration and development company, is pleased to report an upgraded Mineral Resource Estimate ('MRE') at its Pitfield Project in Western Australia ('Pitfield' or the 'Project'), confirming the Project as the world's largest titanium resource. The MRE is reported in accordance with the Joint Ore Reserves Committee ('JORC') 2012 Code (The Australasian Code for Reporting of Exploration Results, Mineral Resources, and Ore Reserves) and includes Measured, Indicated and Inferred categories.

Highlights

• World's largest titanium resource1: upgraded MRE of 8.16 billion tonnes at 4.3% TiO2 for 349 million tonnes of contained TiO2, across the Thomas and Cosgrove deposits

• Including Resource Classifications:

  • Measured: 374 million tonnes at 5.8% TiO2 for 21.6 million tonnes of contained TiO2

  • Indicated: 3.65 billion tonnes at 4.3% TiO2 for 154.7 million tonnes of contained TiO2

  • Inferred: 4.2 billion tonnes at 4.1% TiO2 for 173 million tonnes of contained TiO2

• First Measured Resource declared at Pitfield, defines high-grade material coupled with Indicated Resources, strengthens confidence to progress mine planning and economic studies

• Near-surface, in-situ weathered zone of 4.39 billion tonnes at 4.4% TiO2 for 194.5 million tonnes of contained TiO2: comprising soft, friable material from surface containing naturally formed anatase and rutile, with minimal overburden and no inter-burden, supporting simple, efficient mining methods

• High-grade TiO2 cores define early mining targets with continuous zones averaging above 6% TiO2 over a 5km strike length and up to 1.25km width at Thomas, and over a 4.0km strike length at Cosgrove

• Flowsheet based on conventional processing steps with direct access to global markets: integrated flowsheet demonstrated to produce high-purity (99%+) TiO2 targeting pigment and titanium sponge feedstocks (announced 11 June 2026), with established rail links to deep-water ports serving Asia, the USA, Europe and Saudi Arabia

Shaun Bunn, Managing Director, said: "This upgraded MRE is a landmark moment for Empire Metals and confirms Pitfield as the world's largest titanium resource. To have defined 8.16 billion tonnes at 4.3% TiO2, containing 349 million tonnes of TiO2, underlines the sheer scale of this discovery.

"The scale is only part of the story. The declaration of our first Measured Resource of 374 million tonnes at 5.8% TiO2 containing 21.6 million TiO2, together with a substantial Indicated component, provides the platform for mine planning and the economic studies that will underpin Pitfield's development. This milestone comes just weeks after we demonstrated an integrated flowsheet based on conventional processing steps, producing TiO2 at better than 99% purity, targeting both pigment and titanium metal feedstocks. The high-grade weathered zone sits at surface and lends itself to simple, efficient mining methods. We now have both halves of the equation: a titanium resource of exceptional scale, and an integrated processing route designed to produce high-value products.

"Pitfield has the hallmarks of a tier-one titanium project: scale, grade, simple mining methods, processing route based on conventional processing steps and direct access to global markets, in a strategically important mining friendly jurisdiction."
