KASIYA MINERAL RESOURCE ESTIMATE SIGNIFICANTLY UPGRADED AHEAD OF ANNOUNCEMENT OF DEFINITIVE FEASIBITY STUDY RESULTS

Sovereign Metals has announced an updated Mineral Resource Estimate (MRE) for its flagship Kasiya-Rutile Graphite Project in Lilongwe.

MD and CEO for Sovereign Metals Frank Eagar explains that the updated MRE will serve as the resource base for the Kasiya Definitive Feasibility Study (DFS) mine schedule, replacing the previous April 2023 MRE.

Combined Measured and Indicated rutile Resources have grown 38% to 1,652Mt, now representing 77% of the total Resource base. This material improvement in Resource confidence reflects the extensive infill drilling programs completed and provides a robust foundation for the forthcoming DFS. Importantly, Kasiya has achieved a Measured Resource for the first time, which represents at least the first six years of planned operations.

Eagar comments: “This updated MRE is a significant milestone for Sovereign as we advance Kasiya through the Definitive Feasibility Study. The 32% increase in Measured and Indicated contained rutile, together with our first-ever Measured Resource, reflects both the quality of our geological dataset and the exceptional nature of this deposit. The rigour of the updated resource estimation gives our strategic and commercial partners and us high confidence in the resource base underpinning our potential mine schedule. Kasiya remains unmatched globally as a source of natural rutile, and this MRE update reinforces its potential as a long-life, low-cost supplier to critical global supply chains.”

The updated MRE provides the resource foundation for the upcoming DFS mine schedule and mine optimisation study. The step-up in Measured and Indicated resource confidence is a critical input for the DFS, enabling the Company to present a resource base with the classification level required for bankable project financing and offtake discussions.

Sovereign’s DFS is progressing across all workstreams including mining, processing, infrastructure, environmental and social studies, and commercial arrangements.

MRE EMPHASISES SOVEREIGN’S STRATEGIC SIGNIFICANCE FOR GLOBAL SUPPLY CHAINS

Kasiya is a uniquely diversified source of critical minerals essential to defence, industrial and energy security. The updated MRE demonstrates Kasiya's potential to supply titanium-bearing rutile and graphite for several decades and its position as the world's single most strategically important source of rutile.

Natural rutile is a critical mineral essential to titanium metal production for aerospace, defence and medical applications. According to leading titanium consultants TZ Minerals International Pty Ltd (TZMI), demand for rutile from the titanium metals industry is forecast to grow 3% annually, while global supply is expected to decline by 7% per year over the next decade. The market faces a widening structural deficit

Natural rutile commands a significant premium over alternative titanium feedstocks due to its superior grade (95%+ TiO?), lower processing costs, and smaller environmental footprint. With no meaningful domestic production in key consuming nations, Kasiya’s scale and quality position it as the single most strategically important source of natural rutile outside of current producing regions.

With the updated MRE, Kasiya is positioned to address this critical supply gap at a time when new sources of natural rutile are urgently needed.

The graphite resource further enhances Kasiya's strategic value with a second critical mineral. With graphite demand forecast to grow 9% annually across battery and industrial applications (Benchmark Mineral Intelligence), the Project's 20.0Mt contained graphite provides significant exposure to a valuable by-product.

The establishment of a stable and self-sustaining ecosystem, but not necessarily the one that existed before mining began. In many cases, complete restoration may be impossible, but successful remediation, reclamation, and rehabilitation can result in the timely establishment of a functional ecosystem.



The cleanup of the contaminated area to safe levels by removing or isolating contaminants. At mine sites, remediation often consists of isolating contaminated material in pre-existing tailings storage facilities, capping tailings and waste rock stockpiles with clean topsoil, and collecting and treating any contaminated mine water if necessary.
