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."

Why does Empire Metals describe Pitfield as the world's largest titanium resource?

Empire Metals describes Pitfield as the world's largest titanium resource based on contained TiO2 in its 8.16 billion tonne MRE. According to Empire Metals, this claim uses US Geological Survey titanium resource data and comparisons with publicly reported JORC or equivalent titanium Mineral Resource Estimates.

What is significant about the near-surface weathered zone at Pitfield for Empire Metals shareholders?

The Pitfield weathered zone is reported as 4.39 billion tonnes at 4.4% TiO2, starting at surface. According to Empire Metals, this soft, friable material has minimal overburden and no inter-burden, which supports simple and potentially efficient mining methods for future project development.

What TiO2 product quality has Empire Metals achieved from Pitfield processing test work?

Empire Metals has demonstrated an integrated flowsheet producing TiO2 at better than 99% purity from Pitfield mineralisation. According to Empire Metals, this conventional processing route targets high-purity pigment feedstock and titanium metal sponge feedstock, with access to rail and deep-water ports for global markets.

How does the new Pitfield MRE support future mine planning for Empire Metals (EPMLF)?

The new MRE, including a first Measured Resource and substantial Indicated tonnage, provides a platform for mine planning and economic studies. According to Empire Metals, defined high-grade zones and a large near-surface resource help outline early mining targets and potential development options.

Where are the highest-grade titanium zones located within Empire Metals' Pitfield resource?

High-grade TiO2 cores occur at the Thomas and Cosgrove deposits within Pitfield. According to Empire Metals, continuous zones average above 6% TiO2 over about 5km strike and up to 1.25km width at Thomas, and over roughly 4km strike at Cosgrove.
