Zeus Resources Set to Advance High-Grade Antimony Discovery with Strategic Trenching Program
Zeus Resources Limited (ASX: ZEU) is preparing to advance its 100%-owned Casablanca Antimony Project in central Morocco with an imminent Zeus Resources trenching program that could define the scale of one of the few high-grade antimony exploration projects globally. With final forestry approval pending, the company expects to commence 8 trenches totalling 120 metres in November 2025, targeting surface expressions of high-priority chargeability anomalies identified through recent geophysical surveys.
Furthermore, the Zeus Resources trenching program represents a critical milestone following Zeus's successful August 2025 induced polarisation (IP) survey, which identified multiple chargeability anomalies coincident with mapped Quartz-Stibnite Veins along the strategically important Smaala-Oulmès Fault Zone. With first assay results anticipated before year-end and a maiden drilling campaign planned for Q1 2026, Zeus is positioning itself to capitalise on the supply-constrained antimony market.
Eight Strategic Trenches Target High-Priority Anomalies
Zeus has designed a comprehensive Zeus Resources trenching program targeting the most promising geophysical anomalies across its southern licence block. The program consists of eight trenches, each 15 metres long, 1 metre wide, and 2 metres deep, strategically positioned perpendicular to principal structural trends.
| Trench No. | West Coordinate | North Coordinate | Strike | Length (m) | Width (m) | Depth (m) |
|---|---|---|---|---|---|---|
| TR-1 | 6.465143 | 33.050726 | N135 | 15 | 1 | 2 |
| TR-2 | 6.462877 | 33.052882 | N135 | 15 | 1 | 2 |
| TR-3 | 6.459179 | 33.056421 | N135 | 15 | 1 | 2 |
| TR-4 | 6.445331 | 33.071966 | N135 | 15 | 1 | 2 |
| TR-5 | 6.441680 | 33.075149 | N135 | 15 | 1 | 2 |
| TR-6 | 6.437509 | 33.072730 | N135 | 15 | 1 | 2 |
| TR-7 | 6.431330 | 33.082992 | N135 | 15 | 1 | 2 |
| TR-8 | 6.428053 | 33.082479 | N135 | 15 | 1 | 2 |
| Total | 120 |
Each trench will expose fresh bedrock across mineralised zones, enabling detailed geological mapping and structural measurements. In addition, continuous channel samples will be collected along the full length of each trench and analysed at AfriLab, an ALS-accredited laboratory in Morocco, using four-acid digestion and ICP-OES analysis.
Director Hugh Pilgrim commented: "Securing the final forestry approval will allow Zeus to immediately commence trenching — a pivotal step toward our maiden drill campaign. The trenching results will directly inform our drill planning and further validate the scale of this high-grade antimony system."
Understanding Induced Polarisation: The Technology Behind the Discovery
Induced Polarisation (IP) is a geophysical technique that measures the electrical chargeability of subsurface materials, making it particularly effective for detecting sulphide minerals like stibnite (antimony sulphide). When an electrical current is applied to the ground and then switched off, certain minerals retain an electrical charge longer than others, creating a "polarisation" effect.
Why IP Matters to Investors:
- Direct Detection: IP surveys can directly identify sulphide mineralisation beneath the surface
- Cost-Effective: Significantly cheaper than drilling while providing detailed subsurface information
- Target Definition: Enables precise targeting for expensive drilling programs
- Risk Reduction: Reduces exploration risk by identifying the most prospective areas before committing to drilling
Zeus's August 2025 IP survey identified multiple chargeability anomalies that correlate with known Quartz-Stibnite veins, providing high-confidence targets for the upcoming Zeus Resources trenching program. This technical validation significantly reduces project risk and increases the probability of success for future drilling.
Fast-Track Timeline Leads to Q1 2026 Drilling Campaign
Zeus has established an aggressive timeline designed to maintain exploration momentum and capitalise on market opportunities. However, the systematic approach ensures all necessary validation steps are completed before advancing to the drilling phase.
Immediate Milestones:
- November 2025: Trenching program commences (pending final forestry approval)
- 10-15 days: Expected duration for trenching completion
- December 2025: First assay results from trenching program
- Q1 2026: Maiden drilling campaign targeting refined drill targets
Program Objectives:
- Provide geological and structural controls at geophysical anomalies
- Establish grade continuity at surface across mineralised corridors
- Refine geometry of the Quartz-Stibnite veining system
- Define precise drilling targets for the maiden drill campaign
Consequently, the rapid progression from trenching to drilling reflects Zeus's confidence in the geological model and demonstrates management's commitment to advancing the project expeditiously while antimony prices remain elevated.
Investment Thesis: Exposure to Critical Mineral Supply Crisis
Zeus Resources offers investors direct exposure to antimony, a critical mineral classified as strategic by major economies including the US, EU, Japan, and Australia. The investment case is underpinned by several compelling factors.
Supply Constraint Fundamentals:
- Antimony supply dominated by small number of producers
- Essential for defence, energy storage, and electronics sectors
- Critical applications include flame retardants, lead-acid batteries, and semiconductors
- Increasing strategic importance driving government stockpiling initiatives
What Makes Zeus Resources Unique in the Antimony Space?
Project Advantages:
- High-grade mineralisation: Previous rock chip samples returned 7.8% to 46.52% antimony
