Zeus Resources (ASX:ZEU) has confirmed visible copper mineralisation at surface across its Diaguili Copper‑Gold Project in southern Mauritania following a due diligence site visit.
A Zeus director and technical personnel observed malachite and chrysocolla outcropping on both hills along the historically reported 1km mineralised trend at Diaguili. The trend covers exploration permit 2475B2 in the Guidimaka region.
The outcrop sits directly above historical drilling that returned 22.25m @ 2.1% copper (Cu) from 48m, 35m @ 1.44% Cu from 1m, 33m @ 1.43% Cu from surface, and 12.7m @ 2.94% Cu from 60m. The drilling was shallow, with mineralisation remaining open at depth and along strike.
Zeus collected four rock chip samples across approximately 1.07km of the permit, with copper oxide mineralisation observed. Assays are pending.
The site visit formed part of technical due diligence under Zeus’ definitive share sale agreement to acquire up to 100% of Sab Metals Mauritania, the permit holder. The company announced the acquisition on 23 July 2026.
The project lies within the Mauritanides orogenic belt, which hosts First Quantum Minerals’ (TSX:FM) operating Guelb Moghrein copper‑gold mine. Diaguili is approximately 36km from Selibaby and 7km from Diaguili village.
Zeus located the majority of historical drill collars at or close to its recorded coordinates, including those marked F19 and F23, with concrete collar monuments still visible.
The company says copper oxides occur on fracture surfaces and shear‑controlled ledges in altered chlorite schist, brecciated jaspilite, and serpentinite. Both hills have silicified cores, with widespread magnetite and tremolite‑actinolite veinlets similar to those described at Guelb Moghrein.
Surface features including silicification and the copper‑gold association are consistent with an iron oxide copper‑gold origin, though the deposit model remains unconfirmed pending further work.
The historical exploration results were previously reported by Gryphon Minerals on 12 December 2014 but have not been reported under JORC Code 2012 standards or independently verified by Zeus.
Zeus Resources is an Australian explorer advancing a portfolio of antimony, uranium, copper, lithium, and rare earths projects, including the Casablanca Project in Morocco and the Kalabity Project in South Australia.
