Commencement of Ground-Based Geophysical Programme

VANCOUVER, BC / ACCESS Newswire / March 4, 2026 / Zeb Nickel Corp. (TSXV:ZBNI,OTC:ZBNIF)(OTCQB:ZBNIF) ("Zeb" or the "Company") is pleased to announce that line preparation activities commenced on 2 March along the survey lines required for the planned ground-based geophysical programme at the Zeb Nickel Project.

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.

Ground-Based Geophysical Programme

The ground-based geophysical survey will be conducted over two priority survey areas (as outlined in the map below) and will include:

• High-resolution gravity surveys

• Frequency-domain electromagnetic (FDEM) 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.

Purpose and Benefits

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

• 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.

John Zorbas, Director, commented:

"The commencement of ground-based geophysics represents an important technical step forward for the Zeb Nickel Project. While the airborne programme successfully identified several compelling targets, the higher-resolution ground surveys will allow us to sharpen our focus on the most prospective semi-massive nickel sulphide targets. This work is designed to maximise the effectiveness of our upcoming drilling campaign."
