Completion of MRE Drilling Campaign

Empire Metals Limited, the AIM-quoted and OTCQB-traded exploration and development company, is pleased to announce the successful completion of its largest drilling campaign to date at the Pitfield Project in Western Australia ('Pitfield' or the 'Project'). This programme focussed on high-grade titanium mineralisation within the in-situ weathered cap at the Thomas Prospect and is designed to underpin the Company's maiden JORC compliant Mineral Resource Estimate ('MRE').

Highlights

• 180 drill holes completed at the Thomas prospect, comprising:

o 140 Air Core ('AC') drill holes for a total of 6,360 metres;

o 40 Reverse Circulation ('RC') drill holes for a total of 3,776 metres;

o Total metres drilled: 10,136

• Drilling was conducted on a systematic 400m by 200m grid covering over 1,352 hectares and was designed to support the initial MRE as well as providing key data for economic evaluation studies.
• The Thomas Prospect was selected as the basis for the maiden MRE due to the extensive, thick and high-grade titanium mineralisation hosted within the broad, in-situ weathered zone.
• This campaign marks a major milestone in the development of Pitfield, laying the foundation for a globally significant MRE and enabling the identification of near-surface, high grade zones to support the development of mine planning and ore scheduling as part of upcoming economic evaluation studies.

Shaun Bunn, Managing Director, said: "We are very pleased to have completed this important drilling campaign on time, on budget and without safety incident. With drilling now complete, our focus turns to resource modelling and progressing Pitfield towards its maiden Mineral Resource Estimate, which is a key milestone as we look to bring this globally significant titanium project to commercialisation, maintaining the ambitious development schedule we have delivered over the past two years."

MRE Drilling Programme

With the completion of the current drill campaign, the largest undertaken by the Company to date, total drilling at Pitfield has now surpassed 32,000m across 382 holes, providing a robust foundation for geological modelling, resource definition (refer Figure 1) and initial economic evaluation work.

Since commencing the maiden drilling campaign at Pitfield on 27 March 2023 Empire has completed 382 drill holes for a total 32,265 metres comprising:

• 17 Diamond drill holes for 2,704 m
• 140 RC drill holes for 18,764 m
• 225 AC drill holes for 10,797 m.

May-June 2025 Campaign

The location and spacing of the current RC and AC drillholes were designed, with the input of mineral resource consultants Snowden-Optiro, to provide the necessary drill assay data density to allow the preparation of an MRE at the Thomas Prospect.

The completed drill campaign consisted of 140 AC drillholes, on a 400 x 200m drillhole-spaced grid with an average forecast depth of 45.4m, for a total of 6,360 metres, and 40 RC drillholes within the AC drilling grid, to an average depth of 94.4m, for a total of 3,776 metres. The overall drillhole grid extends 5.2km by 2.6km and totals an area of 1,352 hectares (refer Figure 2).

During the campaign all drill holes were subsampled on a 2m interval, resulting in over 5,000 drill samples being collected, logged by our on-site team of geologists and then prepared for shipment to Intertek's Perth based analytical laboratory. As of the end of June all drill hole and QA/QC samples have been delivered to Intertek for geochemical analysis and assaying.
