URU Metals Limited commenced line preparation activities on 2 March along the survey lines required for the planned ground-based geophysical programme at the Zeb Nickel Project. The line preparation is necessary to provide safe and continuous access for survey crews and equipment, and to ensure accurate data acquisition along the planned gravity and frequency-domain electromagnetic profiles. The line preparation marks the start of the next phase of exploration, aimed at enhancing the resolution and refining the interpretation of the previously completed airborne geophysical surveys.
The ground-based geophysical survey will be conducted over two priority survey areas and will include high-resolution gravity surveys and frequency-domain electromagnetic surveys. These surveys are being undertaken to improve the resolution and accuracy of the airborne EM, magnetic, and gravity datasets previously completed across the Project.

Line preparations along the survey lines commenced in the first survey area on 2 March. While the airborne surveys successfully identified several coincident gravity-magnetic-electromagnetic anomalies and confirmed the presence of a magmatic conduit system, ground-based geophysics provides higher spatial resolution compared to airborne surveys, improved anomaly definition and depth constraints, enhanced discrimination between lithological contrasts and sulphide conductors, and greater confidence in prioritising drill targets. In particular, the frequency-domain electromagnetic survey is designed to better delineate conductive bodies that may represent semi-massive to massive nickel sulphide mineralisation associated with the interpreted magmatic conduit system.
The higher-resolution gravity data will further assist in mapping dense ultramafic bodies and identifying potential sulphide accumulations within structural trap-sites. Together, these surveys are expected to significantly refine drill targeting and reduce exploration risk ahead of the next drilling phase.
