Castle Minerals’ Mineralis Gold Project comprises a large-scale, highly prospective land package of seven exploration permits (one granted and six under application) covering approximately 1,842km² along the Côte d’Ivoire–Ghana border. Castle has a right to earn up to a 90% interest in each permit.

The tenure is strategically positioned within prolific Birimian greenstone belts that host numerous multi-million-ounce gold deposits and producing mines across West Africa. The southern permit lies along the extension of the Bibiani–Chirano belt, approximately 50km southwest of the Chirano Gold Mine in Ghana and within a similar geological setting to Turaco Gold’s Afema Project. The northern permit group is located approximately 25km south of Endeavour Mining’s 4.5Moz Tanda-Iguela (Assafou) discovery and hosts numerous mapped gold occurrences that remain largely underexplored.

Castle is advancing systematic exploration programs across the portfolio focused on rapidly defining drill-ready targets. Work underway includes regional soil geochemistry, structural interpretation and aeromagnetic analysis targeting prospective Birimian structures and mineralised corridors.

At the granted Ebony Permit (PR0965), Castle commenced a 981-sample regional soil geochemistry program covering two prospective Birimian zones using 800m x 100m sampling grids. The program is designed to establish a robust geochemical baseline and refine anomalies for follow-up infill sampling, trenching and first-pass drilling.

Castle continues to progress permitting and tenure consolidation activities across the broader project portfolio, with additional permit approvals anticipated. The Company’s immediate focus is on accelerating exploration and advancing high-priority targets toward initial drilling programs.
