High-Tech Metals Ltd has identified four priority gold target areas (T1 to T4) at the Mt Eureka South Prospect following an integrated interpretation of gradient array induced polarisation, airborne magnetic, and surface geochemical data.

The interpretation, completed with assistance from Resource Potentials, outlines two principal geophysical trend sets across the survey area within Western Australia's Northern Goldfields. The primary feature is a north-south trending resistivity corridor parallel to the regional Hootanui structural and stratigraphic grain, representing an interpreted bedding-related chert unit or weathered banded iron formation horizon. A secondary set of east-west to northeast-southwest oriented chargeability and resistivity anomalies intersects this main corridor, defining prospective structural breaks.

Target T1 lies near the southern commencement of an interpreted structural splay and is characterised by strong resistivity and chargeability anomalies coincident with gold and arsenic surface anomalism. Targets T2 and T3 occur along the main north-south structural corridor, showing distinct resistivity anomalies and broad chargeability responses paired with surface gold and arsenic anomalism. Target T4 is defined by a linear set of chargeability and resistivity anomalies associated with a surface arsenic anomaly. Arsenic serves as a key pathfinder element for hydrothermal and orogenic gold systems in the area, providing a broader geochemical footprint alongside gold.

High-Tech holds a 75% interest in the Mt Eureka Gold Project following the completion of expenditure and reporting requirements under an earn-in agreement with Cullen Resources Ltd. The Mt Eureka Joint Venture and the 100%-owned Mt Fisher Project collectively host a JORC 2012 Mineral Resource Estimate of 3.52 million tonnes at 1.65 grams per tonne gold for 187,000 ounces.

“The identification of four priority target areas, supported by combinations of IP responses, magnetic structure and existing gold and arsenic anomalism, provides a strong basis for the next stage of exploration.”

To advance the prospect, High-Tech Metals will conduct a systematic review of historical drilling across targets T1 to T4 to establish which anomalies remain untested and warrant follow-up reverse circulation drilling. The company also staked one new mineral tenement near the Mt Eureka project in August 2026.
