3 March 2026 - Zeus Resources Limited (“Zeus” or the “Company”) is pleased to announce high- grade antimony (Sb) assay results from the first stage trenching at the Casablanca Antimony Project (“CAP”) in central Morocco.

Following the visual mineralisation reported on 2 February 2026 (“Visible Antimony Oxide Mineralisation Observed in Trench 1 at Casablanca Project”), initial laboratory assays from Trench 1 (T1) and Trench 1A (T1A) have confirmed a robust, high-grade quartz–stibnite system. These results delineate a significant structural corridor along the Smaala–Oulmès Fault Zone, which is the primary control on mineralisation across the 78.6 km2 project area.

Trench T1A was designed as a step-out to test the strike continuity and lateral extent of quartz-hosted antimony mineralisation identified at T1 within a defined mineralised corridor. As part of a systematic trenching programme, Zeus intends to complete up to nine trenches across the CAP licences (Figure 1), with Trenches T2– T8 currently awaiting approval. Trenches T1 and T1A, located approximately 185 metres apart along strike, have returned initial assay results confirming surface continuity of antimony mineralisation, supporting the potential scale of the system and providing a strong foundation for ongoing step-out trenching and targeted drill planning.

Trench Results – T1–T1A Structural Corridor

Trenching at T1 has successfully exposed a sub-vertical quartz–stibnite vein system hosted within folded sandstones and shales. Continuous 1-meter channel sampling returned high-grade results that correlate precisely with the high -chargeability anomalies (10 to 18 mV/V) modelled at depth.

Continuous 1-metre channel sampling at T1 (Figure 2) returned 2 metres averaging 22.69% Sb, with a peak assay of 37.14% Sb. The higher-grade interval is associated with increased quartz veining and visible sulphide (stibnite) mineralisation in the exposed vein system.

24.39% Sb).

Trench 1A (T1A) was positioned 185 m along strike to the northwest to evaluate the lateral persistence of the corridor. Assays confirm the system remains open, returning 3m @ 4.04% Sb (including T1A-01 to T1A-04). Mineralisation in T1A is predominantly oxidised (stibiconite and valentinite), representing the weathered surface expression of the primary stibnite vein system.

Grab samples (T1-06, 07, 08, 11 and 12) from exposed quartz–stibnite veins returned elevated antimony grades, consistent with mineralisation observed in channel samples. Although grab samples are selective and not representative of the average grade, they provide qualitative support for the presence of high-grade mineralisation within the system.

Together, the results confirm the persistence of quartz veining and antimony mineralisation along strike within the same mineralised corridor.

Integrated Geophysics and Predictive Model

The high-grade intercepts in T1 align with the chargeability and resistivity anomalies outlined in the Company’s 9 September 2025 announcement. The geophysical models indicate these targets increase in strength with depth beyond the 200 m imaging limit, suggesting substantial potential for mineralised bodies at depth. The discovery of 37.14% Sb exactly above a major Induced Polarisation (IP) anomaly materially lowers exploration risk for the remainder of the 4 km strike length.

Zeus Executive Director, Hugh Pilgrim, commented:

“Initial trenching and laboratory results at Casablanca are highly encouraging, confirming exceptional near-surface antimony grades and strong along-strike continuity within a robust quartz–stibnite system. The identification of a high- grade core exceeding 22% Sb validates the Company’s targeting approach and demonstrates clear potential for scale. With the Smaala–Oulmès Fault Zone now recognised as a high-grade mineralised corridor, the Company is rapidly advancing exploration to test the remaining 3.8 kilometres of strike.”

Follow-up Work

With Forestry Department approvals now in place for the broader footprint, Zeus has commenced mobilisation for the remaining seven trenches (T2–T8). These trenches are designed to test strike extensions and parallel vein systems identified during mapping and geophysics. Results from this program will form the basis for a maiden drilling campaign targeted for Q2 2026.

Zeus  will  continue  to  update  shareholders  as  trenching  progresses  across remaining trenches (T2, T3, T4, T5, T6, T7 and T8) (refer to coordinate table below).

About Casablanca Antimony Project

The Casablanca Antimony Project is a high-grade mineral exploration project located in central Morocco and comprises six granted exploration licences targeting antimony mineralisation.

During site due diligence, twenty (20) rock-chip samples collected from stibnite- bearing quartz veins across the southern licence area returned high-grade antimony results ranging from 7.8% to 46.52% Sb, confirming the presence of significant surface mineralisation. 1

Subsequent trenching has now further validated this mineralised system. Continuous channel sampling at Trench T1 returned 2 metres averaging 22.69% Sb, with a peak assay of 37.14% Sb, while step-out trench

T1A, located approximately 185 metres along strike, returned 3 metres averaging 4.04% Sb. These results confirm the strike continuity of quartz-hosted antimony mineralisation within the defined corridor.

1 ASX release 9 April 2025 – Zeus Strike Exceptional High Grade Antimony of 46% & 40% Sb

Antimony is classified as a critical mineral by major economies including US, EU, Japan and Australia, due to its vital role in flame retardants, lead-acid batteries, and semiconductors - essential to the defence, energy storage, and electronics sectors. With supply constrained and dominated by a small number of producers, antimony is increasingly viewed as a strategic material. Zeus provides investors with direct exposure to this essential and supply-constrained market.
