Highlights

Zeus Resources has identified an interpreted bedrock conductor at its Diaguili copper-gold project in Mauritania.
The conductor was identified through reprocessing of historical airborne electromagnetic information.
The feature has not been drill tested, and its origin has not been established.
A proposed diamond drilling programme remains dependent on access, approvals and mobilisation.

Zeus Resources Limited (ASX:ZEU) pursues mineral exploration, including copper and gold targets in Mauritania. Its Diaguili project has become the focus of renewed technical work after the reprocessing of historical airborne Geophysical surveys identified an interpreted bedrock conductor. The company intends to test whether that feature has any relationship to known surface and near-surface mineralisation. At present, it is a geophysical target, not a confirmed copper or gold discovery at depth.

How the Conductor Was Identified

The company commissioned reprocessing and three-dimensional modelling of historical airborne electromagnetic data, alongside magnetic interpretation. That work identified a discrete conductive body offset from areas where earlier exploration had reported copper-gold mineralisation. Conductivity can arise from sulphide minerals but also from graphite, saline groundwater and other geological materials. Zeus Resources (ASX:ZEU) therefore cannot infer a copper deposit from the anomaly alone. The value of the model is that it identifies a physical target for a drill hole to intersect and investigate. A well-positioned hole could clarify the source of the response, the host rocks and any relationship to previously sampled mineralisation. A negative intersection would also provide useful information for revising the geological interpretation.

Historic Copper-Gold Work Requires Qualification

Previous explorers reported copper-bearing intervals at Diaguili, giving the company a reason to investigate the broader geological setting. However, the historical programme was conducted under earlier reporting practices, and those results have not all been validated to current JORC standards. Zeus Resources (ASX:ZEU) needs modern quality-control work before relying on those figures in a current mineral resource assessment. Past intersections also do not prove that the interpreted conductor contains the same mineralisation or that there is continuous copper between the two locations. Structural displacement, differing host rocks and the geometry of mineralised zones could explain why targets are separated. This makes careful drill Placement and geological logging important for the first modern tests.

Mauritanian Exploration and Funding Considerations

Diaguili lies in southern Mauritania, and Zeus is pursuing a staged interest in the project through an agreement with the relevant permit holder. Such structures allow exploration exposure to develop in stages, but the milestones and conditions of ownership must be satisfied separately from geological progress. Zeus Resources (ASX:ZEU) must also manage field mobilisation, community engagement and regulatory arrangements in a Jurisdiction outside its home market. Exploration plans are not the same as drilling completed. A contractor must be available, access secured and operational approvals obtained. Further spending may be needed after any first holes, especially if they identify a larger geological system requiring systematic follow-up. No mine development or production outcome can currently be inferred.

The Next Technical Decision

The proposed programme involves maiden diamond drilling at the geophysical target and evaluation of extensions to historically reported mineralisation. Diamond core can allow detailed structural mapping and sampling across the conductor, helping separate sulphide-bearing rock from non-mineral conductive material. Zeus Resources (ASX:ZEU) has identified the December 2026 quarter as its intended drilling window, subject to the necessary arrangements. The next milestone is drilling and laboratory assays. Any future resource estimate would require sufficient drilling density and independently supported interpretation. Until then, the target remains speculative in the technical sense: its dimensions and composition have not been demonstrated underground.

Key Insights

Zeus Resources (ASX:ZEU) has refined its Diaguili exploration programme around an untested geophysical conductor. The feature may help direct drilling, but historic copper indications and conductivity do not establish a mineral deposit. Access, approvals, drilling and assays are the immediate tests.
