Empire Metals Limited Announces Drilling Outlines Large, High-Grade Zone

Major Drilling Campaign Outlines Large, High-Grade Zone

LONDON, UNITED KINGDOM / ACCESS Newswire / August 18, 2025 / Empire Metals Limited,theAIM-quoted and OTCQB-tradedexploration and development company,is pleased to report outstanding assay results from its latest drilling campaign at the Pitfield Project in Western Australia ('Pitfield' or the 'Project'). This programme, focused on the in-situ weathered cap at the Thomas Prospect, has delivered some of the highest titanium dioxide ('TiO₂') grades recorded to date and will underpin the Company's maiden JORC-compliant Mineral Resource Estimate ('MRE').

Highlights

• Selected exceptional intercepts (>6% TiO₂), include:

• Large, high-grade central core identified averaging circa 6% TiO₂ across a continuous 3.6km strike length.

• Nearly two thirds of all drillholes averaged > 4% TiO₂, with over 90% exceeding a 2% cut-off.

Shaun Bunn, Managing Director, said:"These results confirm the exceptional scale and grade of titanium mineralisation at Thomas. The continuity of high-grade mineralisation near surface is particularly exciting for future mine development. With assays received ahead of schedule, we can now accelerate resource modelling and move rapidly towards announcing our maiden MRE."

MRE Drilling Programme - Key Results

Since commencing the maiden drilling campaign at Pitfield on 27 March 2023 Empire has completed 382 drill holes for a total 32,265 metres (refer Figure 1) comprising:

• 17 Diamond drill holes for 2,704 m

• 140 Reverse Circulation (RC) drill holes for 18,764 m

• 225 Air Core (AC) drill holes for 10,797 m.

The latest May-June campaign comprised:

• 140 AC drillholes (6,360m) on a 400 x 200m grid, average depth 45.4m

• 40 RC drillholes (3,776m) within the AC grid, average depth 94.4m

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. The analytical assay results have now been received, showing continuous TiO₂-rich mineralisation across the overall drillhole grid, which extends 5.2km by 2.6km and totals an area of 1,352 hectares (refer Figure 2).

The drilling has confirmed the presence of a large, high-grade central core at the Thomas prospect, this target being selected as the basis for the maiden MRE due to the extensive, thick and high-grade titanium mineralisation known to be hosted within the broad, in-situ weathered zone. Whilst over 90% of all drillhole sample assays show mineralisation well above a 2% TiO₂ cut-off grade this central high-grade core, extends over 3.6km north-south, averages around 6% TiO₂ (refer Table 1).

Significant analytical assay results for each drillhole above 6% TiO₂ are reported in Table 2 further below.

Strategic Significance

The May-June campaign marked 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.

The Pitfield Titanium Project

Located within the Mid-West region of Western Australia, near the northern wheatbelt town of Three Springs, the Pitfield titanium project lies 313km north of Perth and 156km southeast of Geraldton, the Mid West region's capital and major port. Western Australia is a Tier 1 mining jurisdiction, with mining-friendly policies, stable government, transparency, and advanced technology expertise. Pitfield has existing connections to port (both road & rail), HV power substations, and is nearby to natural gas pipelines as well as a green energy hydrogen fuel hub, which is under planning and development (refer Figure 3).

About Empire Metals Limited

Empire Metals is an AIM-listed and OTCQB-traded exploration and resource development company (LON: EEE) 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 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, 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 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.
