("Empire" or "the Company")

Inclusion in FTSE AIM 100 Index

Empire Metals Limited (LON:EEE), the AIM-quoted and OTCQX-traded resource exploration and development company, is pleased to announce that the Company has become a constituent of the FTSE AIM 100 Index.

This outcome follows FTSE Russell's quarterly review of the FTSE AIM UK 50, FTSE AIM 100 and FTSE AIM All-Share Indices. Changes were applied after the close of business on 22 September 2025.

Commenting on the announcement, Shaun Bunn, Managing Director, said:

"We are delighted to announce Empire Metals' inclusion in the FTSE AIM 100 index; a solid milestone that reflects the momentum we have built with the Company over recent years. Since uncovering the giant, high-grade titanium anomaly at Pitfield in 2022, we set an ambitious development timeline and have subsequently demonstrated that we have a project of unprecedented scale and purity, with the potential for a truly multi-generational mine life.

"This achievement is only possible thanks to the hard work and expertise of our team and the backing of our shareholders. Together, we're positioning Pitfield to become a transformational, world-class titanium asset and unlocking its full potential through commercialisation."

About Empire Metals Limited

Empire Metals is an AIM-listed and OTCQX-traded exploration and resource development company (LON: EEE, OTCQX: EPMLF) with a primary focus on developing Pitfield, an emerging giant titanium project in Western Australia.

The high-grade titanium discovery at Pitfield is of unprecedented scale, with airborne surveys identifying a massive, coincident gravity and magnetics anomaly extending over 40km by 8km by 5km deep. Drill results have indicated excellent continuity in grades and consistency of the in-situ mineralised beds and confirm that the sandstone beds hold the higher-grade titanium dioxide (TiO₂) values within the interbedded succession of sandstones, siltstones and conglomerates. The Company is focused on two key prospects (Cosgrove and Thomas), which have been identified as having thick, high-grade, near-surface, in-situ bedded TiO₂ mineralisation, each being over 7km in strike length.

An Exploration Target* for Pitfield was declared in 2024, covering the Thomas and Cosgrove mineral prospects, and was estimated to contain between 26.4 to 32.2 billion tonnes with a grade range of 4.5 to 5.5% TiO2. Included within the total Exploration Target* is a subset that covers the in-situ weathered sandstone zone, which extends from surface to an average vertical depth of 30m to 40m and is estimated to contain between 4.0 to 4.9 billion tonnes with a grade range of 4.8 to 5.9% TiO2.

The Exploration Target* covers an area less than 20% of the overall mineral system at Pitfield which demonstrates the potential for significant further upside.

Empire is now accelerating the economic development of Pitfield, with a vision to produce a high-value titanium metal or pigment quality product at Pitfield, to realise the full value potential of this exceptional deposit.

The Company also has two further exploration projects in Australia; the Eclipse Project and the Walton Project in Western Australia, in addition to three precious metals projects located in a historically high-grade gold producing region of Austria.

\* The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. See RNS dated 12 June 2024 for full details.
