Casablanca Project Yields Multiple High-Priority Antimony Anomalies Beyond 200m Depth

Geophysical Survey Validates Exploration Model

Zeus Resources Limited (ASX – ZEU) has announced compelling results from a recent ground geophysical survey at its Casablanca Antimony Project in central Morocco. The survey, which employed dipole–dipole resistivity and induced polarisation (IP) techniques, successfully delineated multiple chargeability anomalies that align closely with previously mapped quartz-stibnite veins. These findings provide a robust geophysical signature that materially lowers exploration risk and confirms the presence of mineralised structures controlled by the Smaala–Oulmès Fault Zone.

Depth Potential and Structural Insights

One of the most significant outcomes is the observation that chargeability anomalies not only exist near surface but also intensify with depth, often extending beyond the survey’s reliable imaging limit of approximately 200 to 230 meters. This depth continuity suggests a substantial mineralising system with promising potential for significant antimony deposits at depth. The geophysical data also highlight structural corridors trending northeast-southwest, reinforcing the interpretation of mineralisation controlled by fault-related quartz-stibnite veins.

Correlation with High-Grade Surface Sampling

The geophysical anomalies correspond with high-grade surface rock-chip samples collected across the southern license area, where assays have returned antimony grades exceeding 10%, with some samples reaching as high as 46.52% Sb. This strong correlation between geophysical targets and surface geochemistry enhances confidence in the exploration model and supports the prioritisation of targets for follow-up work.

Next Steps – Trenching and Drilling

Building on these encouraging results, Zeus Resources plans to commence a trenching program shortly. This will provide direct geological control and fresh subsurface samples to better understand the structural orientation and mineralisation style. Following trenching, a drilling campaign is planned to test the most compelling anomalies at depth. The drilling strategy will focus on inclined holes to intersect the sub-vertical mineralised veins and vertical holes to target well-rooted chargeable bodies, aiming to delineate the extent and grade of the antimony mineralisation.

Strategic Importance of Antimony and Moroccan Mining Context

Antimony is recognised globally as a critical mineral essential for flame retardants, lead-acid batteries, and semiconductors, with supply chains currently constrained by geopolitical risks. Morocco’s stable and mining-friendly environment, combined with its geological potential, positions the Casablanca Project as a strategically significant asset. Zeus Resources’ systematic and disciplined approach to advancing this project aligns well with the growing demand for secure critical mineral supplies.
