- Systematic soil geochemistry and aeromagnetic surveys progressing in Côte d’Ivoire
- Steve Zaninovich appointed full-time Managing Director to drive dual-region growth
- Cash position stands at A$2.25 million with A$346,000 exploration spend in Q1 2026
- Polelle and Wanganui projects fully retained for accelerated exploration
Dominant Landholding Established in Murchison Gold District
Castle Minerals Limited (ASX:CDT) has significantly expanded its Western Australian presence by acquiring 100% of Meekasan Pty Ltd, adding 68 km² of contiguous greenstone tenure to its existing Polelle and Wanganui projects. This acquisition brings Castle’s total landholding in the prolific Meekatharra gold district to approximately 184 km², positioning it as a dominant junior explorer in a proven gold corridor.
The Meekasan ground lies immediately adjacent to Westgold Resources’ Paddy's Flat operation, which boasts historic production exceeding 1.5 million ounces, and near Great Boulder Resources’ Side Well and Mulga Bill deposits. The tenure covers over 30 km of prospective greenstone strike with only shallow, wide-spaced historical drilling, underscoring substantial exploration upside.
Castle plans to undertake a comprehensive soil geochemistry program across the Meeka South Gold Project to define mineralisation signatures, complemented by field verification of magnetic targets and follow-up air core or RC drilling. The strategic acquisition and exploration plan reflect the company’s ambition to unlock value in a region benefiting from strong infrastructure and a robust gold price environment. This follows the earlier announcement of the acquisition and leadership changes that aimed to accelerate growth Castle Minerals Secures 184km² in WA Gold District with Strategic Meekasan Buy.
Advancing Côte d’Ivoire Exploration Toward Drill-Ready Targets
In West Africa, Castle’s exploration efforts continue across a substantial ~1,842 km² land package straddling the Côte d’Ivoire–Ghana border, acquired via Mineralis Ltd with rights to earn up to 90% interest. The granted Ebony permit (343.1 km²) is the focus of an ongoing regional soil sampling campaign designed to establish a geochemical baseline. The program covers 981 samples on 800m by 100m grids targeting two prospective Birimian greenstone zones, with results expected to refine anomalies and guide infill sampling, trenching, and initial drilling.
Permitting progress remains steady, with community agreements near ratification to enable resumption of ground access. The company anticipates approvals for two additional permits early next quarter, including southern licences along the Bibiani–Chirano belt, a region known for hosting multi-million ounce gold mines. The northern permit cluster lies about 25 km south of Endeavour Mining’s Tanda-Iguela discovery, an area with known gold occurrences but limited systematic exploration.
Castle is integrating soil geochemistry, structural interpretation, and aeromagnetic data to prioritise high-impact, drill-ready targets across its West African portfolio, reflecting a methodical approach to exploration in a region with significant gold endowment.
Leadership Reshuffle to Drive Dual-Region Strategy
Castle Minerals has realigned its leadership structure to sharpen operational focus and governance as it advances exploration in both Western Australia and West Africa. Steve Zaninovich, previously Non-Executive Chairman, was appointed full-time Managing Director effective 1 March 2026. Zaninovich brings over three decades of resource sector experience, including extensive West African gold exploration, project development, and M&A expertise. His appointment aims to accelerate execution of Castle’s dual-platform discovery strategy.
Andrew Grove transitioned to Non-Executive Chairman, providing governance oversight backed by over 30 years of mining experience across West Africa and Australia. Mohamed Niaré stepped down from the board to become In-Country Project and Business Development Manager for Côte d’Ivoire, ensuring dedicated on-ground leadership and stakeholder engagement. This operational realignment signals Castle’s commitment to advancing its West African portfolio with enhanced local expertise and strategic oversight.
Financial Position and Exploration Outlook
Castle ended the March quarter with A$2.25 million in cash and incurred A$346,000 in exploration expenditure. No mining production occurred during the period. The company retains 100% ownership of its Polelle and Wanganui projects after allowing a Great Boulder Resources option to lapse, positioning it to accelerate exploration in these promising Western Australian assets.
Meanwhile, in Ghana, Castle continues to assess assay results from auger drilling at Kandia and Bulenga, with full analysis expected next quarter to inform potential drilling campaigns. The Kambale Graphite Project remains inactive as Castle explores monetisation options.
Castle’s strategic land acquisitions, systematic exploration programs, and leadership enhancements collectively aim to position the company for value creation amid a favourable gold price environment. However, exploration results remain preliminary, and permitting timelines in Côte d’Ivoire retain some uncertainty, factors that will influence the pace of progress in coming quarters.
Bottom Line?
Castle Minerals is strategically positioned with a dominant WA landholding and advancing West African targets, but exploration remains early stage with a limited cash runway.
Questions in the middle?
- How will assay results from Côte d’Ivoire’s soil sampling influence near-term drilling plans?
- What exploration milestones will Castle prioritize to unlock value across its expanded Murchison footprint?
- Can the leadership realignment accelerate permitting and operational execution in West Africa?
