Casablanca Project’s Geophysics Reveal Multiple Drill-Ready Antimony Anomalies

Exploration Advances at Casablanca

Zeus Resources Limited (ASX, ZEU) has announced an important update to its exploration efforts at the Casablanca Antimony Project in central Morocco. The company has amended its JORC Table 1 to reflect new data from a recently completed ground geophysical survey, which has highlighted multiple high-priority targets for antimony mineralisation.

The survey employed dipole–dipole resistivity and induced polarisation (IP) techniques across 25 profiles, covering approximately 16 kilometres of key structural trends. These geophysical methods have successfully delineated chargeability anomalies that coincide with mapped quartz-stibnite veins, a classic signature of antimony mineralisation. Notably, these anomalies often intensify with depth and extend beyond the survey’s reliable imaging limit of around 200 metres, suggesting a robust and potentially deep mineralising system.

Structural Controls and Geological Context

The mineralisation is structurally controlled by the Smaala–Oulmès Fault Zone, a regional NNE-striking fault system that hosts dilational jogs favourable for stibnite (antimony sulphide) deposition. The geophysical data reveal resistant corridors interpreted as quartz veins filled with stibnite, which have been confirmed by high-grade surface rock chip samples returning antimony grades exceeding 10% Sb, with some samples reaching up to 46.5% Sb.

This integration of geophysical and geochemical data significantly lowers exploration risk and strengthens the case for advancing the project. The company’s approach to exploration is methodical, with trenching planned to test surface expressions of the anomalies. These trenches will provide critical geological and structural information, as well as fresh samples to refine targeting for the upcoming drilling campaign.

Strategic Importance and Regional Advantages

Antimony is classified as a critical mineral by major economies due to its essential role in flame retardants, batteries, and semiconductors, combined with supply chain vulnerabilities. Zeus’s Casablanca Project benefits from Morocco’s stable and mining-friendly regulatory environment, modern mining code, and strategic location, which collectively enhance the project’s attractiveness to investors and stakeholders.

The company’s management team brings extensive expertise in mineral exploration and is focused on efficiently scaling operations to maximise shareholder value as the project advances. The forthcoming trenching and drilling programs will be pivotal in confirming the size and grade continuity of the mineralised zones, potentially positioning Casablanca as a significant new source of antimony.

Looking Ahead

With trenching set to commence shortly and drilling planned to follow, Zeus Resources is poised to systematically test and expand its understanding of the mineralisation at Casablanca. The results of these programs will be closely watched by the market, given the strategic importance of antimony and the promising early-stage data.
