Australian explorer Zeus Resources has identified a new drilling target at its Diaguili copper-gold project in southern Mauritania's Guidimakha region and plans to test it in the final quarter of 2026.
In an announcement dated October 12, Zeus said reprocessing a 2008 airborne electromagnetic survey and building a three-dimensional model had outlined a conductive rock zone about 1.7 kilometres long and up to 500 metres wide. The model places it roughly 150 to 170 metres below the surface, east of most historical drill sites.
The company said earlier drilling had not reached the target. Of 48 historical holes with recorded depths, 43 did not reach 100 metres vertically. Its planned first diamond-drilling programme will test the conductor and deeper extensions of known mineralisation, subject to drilling-contractor availability and site access.
The work replaces a preliminary interpretation presented in July, which placed the conductor beneath the area previously drilled. The new model locates it in an adjacent area, following analysis by Perth-based Southern Geoscience Consultants.
The project is held under exploration permit 2475B2 through Sab Metals Mauritania, in which Zeus is acquiring a staged interest under an agreement announced on July 23. The latest development is the selection of a geological test target, not a mineral-reserve estimate. Drilling will establish the nature of the conductive rocks and their possible connection to copper and gold.
