Zeus Resources Confirms High-Grade Antimony Discovery at Casablanca Project with Outstanding 22.69% Sb Results
Zeus Resources Limited (ASX:ZEU) has delivered exceptional antimony assay results from its maiden trenching programme at the Casablanca Antimony Project in Morocco, confirming both high-grade mineralisation and significant strike continuity across a robust structural corridor. This Zeus Resources Ltd high-grade antimony discovery represents a significant milestone for the company and positions it as a key player in the critical minerals sector.
The standout results from Trench 1 (T1) include a 2-metre intercept averaging 22.69% antimony (Sb), with a peak assay reaching 37.14% Sb from massive stibnite mineralisation. Furthermore, strike continuity has been confirmed 185 metres away in step-out Trench 1A, which returned 3 metres averaging 4.04% Sb, demonstrating the scale potential of this emerging antimony system.

Exceptional Grade Validation Across Strike Length
The initial trenching programme has successfully exposed a sub-vertical quartz-stibnite vein system within the Smaala-Oulmès structural corridor. Continuous 1-metre channel sampling at T1 returned the exceptional 2m @ 22.69% Sb interval, with mineralisation precisely correlating to the high-chargeability anomalies (10 to 18 mV/V) previously modelled at depth.
| Trench | Interval | Average Grade | Peak Grade | Distance from T1 |
|---|---|---|---|---|
| T1 | 2m | 22.69% Sb | 37.14% Sb | – |
| T1A | 3m | 4.04% Sb | 5.91% Sb | 185m along strike |
The T1A step-out trench, positioned 185 metres northwest along strike, confirms the lateral persistence of the mineralised corridor. According to the company announcement, assays from T1A show the system remains open, with mineralisation predominantly appearing as oxidised antimony minerals (stibiconite and valentinite) representing the weathered surface expression of the primary stibnite system below.
Key highlights from the channel sampling include:
- T1-10: 37.14% Sb (peak assay from massive stibnite)
- T1-09: 27.41% Sb (channel sample)
- T1-08: 21.37% Sb (grab sample from exposed quartz-stibnite veins)
- T1A-02: 5.91% Sb (channel sample from oxidised zone)
Geophysical Model Validation Reduces Exploration Risk
The discovery of 37.14% Sb directly above a major Induced Polarisation (IP) anomaly represents a significant validation of Zeus's geophysical targeting approach. The high-grade intercepts in T1 align precisely with the chargeability and resistivity anomalies identified in the company's August 2025 survey.
According to the company, geophysical models indicate these targets increase in strength with depth beyond the 200-metre imaging limit, suggesting substantial potential for mineralised bodies at depth. Consequently, this correlation materially reduces exploration risk for the remainder of the 4-kilometre strike length that remains to be tested.
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. – Hugh Pilgrim, Executive Director
Understanding Antimony: A Critical Mineral Opportunity
What is Antimony?
Antimony is a metalloid element primarily used in flame retardants, lead-acid batteries, and semiconductor applications. The element is classified as a critical mineral by major economies including the US, EU, Japan, and Australia due to its essential role in defence, energy storage, and electronics sectors.
Why It Matters for Investors
The global antimony market is highly concentrated, with supply dominated by a small number of producers, making it increasingly viewed as a strategic material. Current market dynamics show constrained supply against growing demand from emerging technologies, creating significant opportunities for new discoveries like Casablanca.
Zeus's antimony project provides investors with direct exposure to this supply-constrained critical mineral at a time when global supply security is becoming increasingly important to major economies. This Zeus Resources Ltd high-grade antimony discovery comes at an opportune moment in the market cycle.
Key Applications Include:
- Flame Retardants: Essential component in fire safety materials
- Lead-Acid Batteries: Critical hardening agent improving battery performance
- Semiconductors: Growing demand from electronics and renewable energy sectors
- Defence Applications: Strategic material for military and aerospace industries
Accelerated Exploration Programme Ahead
With Forestry Department approvals now secured for the broader project footprint, Zeus has commenced mobilisation for the remaining seven trenches (T2-T8). These trenches are strategically designed to test strike extensions and parallel vein systems identified during geological mapping and geophysical surveys.
Upcoming Exploration Timeline:
- Immediate: Trenches T2-T8 across the 4km mineralised corridor
- Q2 2026: Maiden drilling campaign based on trenching results
- Ongoing: Systematic testing of geophysical targets along strike
The trenching programme will span 144 metres total length across eight trenches, each designed to intersect the structural corridor at perpendicular angles to ensure true width measurements. In addition, results from this expanded programme will form the foundation for Zeus's maiden drilling campaign targeted for Q2 2026.
| Trench | Strike | Length (m) | Width (m) | Depth (m) | Status |
|---|---|---|---|---|---|
| T1 | N135 | 24 | 1 | 2.5 | Completed |
| T1A | N135 | 15 | 1 | 1.5 | Completed |
| T2-T8 | N135 | 15 each | 1 | 2.0 | Planned |
| Total | – | 144 | – | – | – |

Casablanca Project Technical Summary
The Casablanca Antimony Project comprises six granted Exploration Research Licences covering 78.6 square kilometres in central Morocco. The project is strategically located within the Smaala-Oulmès Fault Zone, which serves as the primary structural control on mineralisation across the project area.
Project Characteristics:
- Location: Central Morocco, established mining jurisdiction
- Tenure: Six granted exploration licences in good standing
- Strike Length: 4 kilometres of identified mineralised corridor
- Mineralisation Style: Sub-vertical quartz-stibnite veins in folded sediments
- Target Depth: Geophysical anomalies extend beyond 200 metres depth
The mineralisation is hosted within folded sandstones and shales, with antimony occurring as semi-massive stibnite (Sb₂S₃) and secondary oxides widely distributed throughout a dilational jog developed in the regional fault system. However, this Zeus Resources Ltd high-grade antimony discovery extends beyond typical expectations for the geological setting.
