Highlights

  • Drilling at the Thomas Prospect delivered multiple high-grade titanium intercepts, including 98m at 7.05% TiO₂.

  • A continuous high-grade central core averaging around 6% TiO₂ was identified across a 3.6km strike length.

  • Over 90% of all drillholes exceeded the 2% TiO₂ cut-off grade, with nearly two thirds averaging above 4% TiO₂.

Empire Metals Limited (AIM:EEE; OTCQB:EEEEF), an exploration and development company, announced assay results from its latest drilling programme at the Pitfield Project in Western Australia. The programme focused on the in-situ weathered cap at the Thomas Prospect and delivered some of the highest titanium dioxide (TiO₂) grades reported at the site, supporting the Company’s plans for its maiden JORC-compliant Mineral Resource Estimate (MRE).

Drilling Results

The latest assays confirmed continuous TiO₂-rich mineralisation across a grid covering 5.2km by 2.6km, totalling 1,352 hectares. Exceptional intercepts above 6% TiO₂ included 44m at 7.87% from surface (AC25TOM159), 50m at 7.84% from 4m (AC25TOM130), and 98m at 7.05% from 2m (RC25TOM062 and RC25TOM068). Nearly two-thirds of drillholes averaged more than 4% TiO₂, while over 90% exceeded the 2% TiO₂ cut-off grade.

The drilling programme confirmed the presence of a large, high-grade central core averaging approximately 6% TiO₂ along a 3.6km strike length. This area has been prioritised for the maiden MRE due to the thickness and grade of titanium mineralisation in the weathered zone.

Drilling Campaign

Since the maiden drilling campaign began in March 2023, Empire Metals has completed 382 drillholes for a total of 32,265 metres, comprising 17 diamond drillholes (2,704m), 140 reverse circulation (RC) holes (18,764m), and 225 air core (AC) holes (10,797m).

The May–June 2025 programme included 140 AC drillholes totalling 6,360m and 40 RC drillholes totalling 3,776m. Drillholes were completed on a 400 x 200m grid, with average depths of 45.4m for AC and 94.4m for RC holes. All drillholes were subsampled at 2m intervals, generating more than 5,000 samples, which were processed at Intertek’s Perth laboratory.

Strategic Progress

The results confirm Pitfield’s potential to host significant titanium mineralisation. The May–June campaign was a key milestone in advancing the project, providing data that will form the basis of the maiden MRE. The identification of near-surface high-grade zones is expected to support future mine planning and ore scheduling as part of upcoming economic assessments.

Empire Metals continues to prioritise the Thomas Prospect as the foundation for its resource estimate, while advancing exploration across the wider Pitfield project area. The high recovery rates across drillholes strengthen the case for Pitfield as a globally significant titanium project.

Project Overview

Pitfield is located in the Mid-West region of Western Australia, approximately 313km north of Perth and 156km southeast of Geraldton. The project benefits from proximity to existing infrastructure, including port facilities, road and rail links, high-voltage substations, and gas pipelines. The site is also near a planned green energy hydrogen hub, further enhancing its strategic position.
