The Tata Project covers 138.6 km2, comprising nine licence blocks, with access via asphalt roads and a network of smaller tracks. The Company holds a 100 % interest in the Project, located in the western Anti-Atlas Mountains, a region considered highly prospective for sedimentary-hosted copper mineralisation.

The Tata Project occurs approximately 165 km southeast of the port city of Agadir and 50 km southeast of the Tizert copper-silver project (estimated resources of 57 Mt grading 1.03 % Cu and 23 g/t Ag), currently under development by Managem Group. 

The Project lies 30 km south of the Company’s Azrar copper-silver project.

Late Ediacaran to early Cambrian-aged Adoudounian sediments occur within the Project along the margins of the Paleoproterozoic Tagragra de Tata Inlier. These sedimentary units are known to host copper mineralisation within the Anti-Atlas and represent the primary copper target on the Project.

The Company acquired line data, in 2024, covering over 250 km2 from historical airborne geophysical surveys flown over the Tata and 

 from the Ministry of Energy, Transition and Sustainable Development in Rabat, Morocco. The surveys were flown in 1998-1999 by Geoterrex Dighem Pty., collecting magnetometry, gamma-spectrometry, and multi-frequency electromagnetic data. This data has been reprocessed and reinterpreted as part of an ongoing target generation exercise over the projects.

 – Four priority targets covering a cumulative 14.3 km strike length. Copper mineralisation extended within two mineralised stratigraphic horizons and is visible on the surface. 

32 km of combined prospective strike length has been identified to date. 13 km combined strike length of target horizons remains untested. 

Mineralised apparent thicknesses of up to 8.5 m within the basal Adoudou Formation returned: Up to 1.50 % Cu, 0.97 Cu %, and 0.32 % Cu from an 8 m thick carbonate sequence. Up to 1.02 % Cu, 0.51 % Cu, and 0.48 % Cu from an 8.5 m thick carbonate sequence.

Primarily targeting Copper – Silver, in addition to Au, Sn, Zn & Pb

Projects are located mainly in the Anti-Atlas Mountains, as well as the High Atlas and Central Morocco.

The Anti-Atlas is highly prospective for sedimentary-hosted copper.

: up to 7.02 % Cu from sediments, over 32 km of mineralised strike

: up to 4.43 % Cu from quartz-carbonate vein swarm

: initial assay grades up to 3.41 % Cu and 56 g/t Ag in breccia and 1 % Cu and 16 g/t Ag from ferruginous stratiform sample. 0.82 g/t Au and 0.63 % Cu over 9.0 m from surface chip channel targeting northerly strike quartz veins

: up to 170 g/t Ag and 22.2 % Pb from quartz veins and fault beccias

A "new" copper - silver - gold and poly-metallic frontier.

at the Tata Project will include further geological mapping to explore the copper potential in the untested areas of the sedimentary package, supported by detailed mapping and channel samples at selected locations perpendicular to the bedding/stratigraphy. Ground-based geophysical surveys will aid in drill hole planning based on the surface mapping and sampling outcomes and will be supported by the airborne geophysical data re-interpretation.
