Sovereign Metals' Kasiya Project Uncovers Heavy Rare Earths, Signs Strategic Offtake MOU

Sovereign Metals’ interim results: Kasiya adds heavy rare earths and lands a graphite offtake path

Sovereign Metals has filed its half-year report to 31 December 2025, and there’s plenty for investors to unpack. The company is pushing its Kasiya rutile-graphite project in Malawi through a Definitive Feasibility Study (DFS) while adding a potentially valuable third by-product in heavy rare earths. A non-binding offtake MOU with Traxys for graphite also sharpens the commercial picture.

All figures below are as disclosed in the RNS and denominated in Australian dollars unless stated otherwise.

Heavy rare earths from tailings: why Dy, Tb and Y are a big deal

Post period, Sovereign recovered monazite concentrate from Kasiya’s rutile tailings stream. Early analysis indicates “exceptionally elevated” levels of dysprosium and terbium (often referenced together as DyTb), plus yttrium – all critical heavy rare earths used in high-temperature permanent magnets and advanced defence and aerospace applications.

Here’s the punchline: it’s a by-product from material already being processed for rutile, so management sees the potential for a third revenue stream at near-zero incremental cost. The company notes basic monazite concentrate is currently selling for over US$8,500/t delivered to China. With China tightening export licensing on these heavy rare earths, western-aligned supply from Malawi is strategically attractive.

What to watch next: detailed mineralogical characterisation, recoveries through the proposed flowsheet, and the potential scale and economics of rare earth production are all flagged for upcoming updates. Until those numbers land, treat the opportunity as promising but unquantified.

Traxys MOU: a sales pathway for Kasiya’s graphite

Also after the period, Sovereign signed a non-binding memorandum of understanding with Traxys North America to market graphite from Kasiya. Traxys is one of only three trading houses appointed to procure critical minerals for the US Government’s US$12 billion Project Vault stockpiling initiative. That’s useful validation and potentially a route into US supply chains.

• Stage 1 target: 40,000 tonnes per annum of graphite concentrate (Years 1-5)
• Thereafter: up to 80,000 tonnes per annum
• Initial focus: high-value flake graphite for the refractory market, with potential to include flake graphite for battery anodes

It’s non-binding, so it’s not bankable yet, but it signals market appetite and provides a framework to progress into formal offtake agreements during or after the DFS.

DFS progress: geotech ticked off, mining fleet defined, rehab results encouraging

Sovereign reports several key DFS components are now complete:

• Geotechnical work across mining areas, tailings and raw water dam – over 400 tests – showed favourable and consistent subsurface conditions.
• Mining fleet selection finalised for large-scale dry mining. Kasiya requires no drilling, blasting, crushing or milling – an important lever for capital and operating cost discipline.
• Land rehabilitation trials from the pilot phase achieved a 5x crop yield improvement over traditional farming in year one, supporting the project’s social licence and progressive rehab strategy.

The company is integrating the International Finance Corporation’s (IFC) Performance Standards into the DFS and Environmental and Social Impact Assessment. The IFC has also secured rights to participate in financing – a strong signal for project bankability when the time comes, subject to Rio Tinto’s existing rights under the Investment Agreement.

Financial snapshot: lower loss, strong cash, but ongoing spend

The half-year loss narrowed to $8,986,797 (2024: $19,546,116). That improvement was helped by a non-cash share-based payment benefit of $7,750,775 after the company determined certain performance rights would lapse unvested. Underlying spend remains focused on the DFS, with exploration and evaluation expenses of $16,098,372.

Key figures (half-year to 31 Dec 2025)	$
Loss after tax	8,986,797
Exploration & evaluation expense	16,098,372
Business development	815,461
Interest income	902,176
Operating cash outflow	20,411,933
Cash and cash equivalents (31 Dec)	33,937,352
Net assets (31 Dec)	38,704,181
Debt	Nil

Cash fell from $54,538,435 to $33,937,352 as the DFS advanced. Operating cash outflow was $20,411,933 across six months. At that burn rate, the cash runway is adequate for the near term, but investors should expect the company to stay focused on financing options as it moves from DFS into project funding. The auditor’s independent review found nothing to suggest the report does not give a true and fair view (note: a review is not an audit opinion).

Resource and reserve: Kasiya remains Tier 1 in scale

Kasiya is described as the world’s largest natural rutile deposit and the second-largest flake graphite deposit. The Optimised Pre-Feasibility Study completed last year reaffirmed the potential to be a large, low-cost producer; the DFS is due in the coming months.

Ore Reserve (Probable)	Tonnes (Mt)	Rutile grade (%)	Contained rutile (Mt)	Graphite grade (TGC %)	Contained graphite (Mt)
Total Probable	538	1.03	5.5	1.66	8.9

Mineral Resource (Indicated + Inferred)	Resource (Mt)	Rutile grade (%)	Contained rutile (Mt)	Graphite grade (TGC %)	Contained graphite (Mt)
Total	1,809	1.0	17.9	1.4	24.4

Scale matters for offtakers, financiers and strategic partners. Add in the by-product monazite and the project now spans three critical mineral streams – rutile (titanium), graphite, and heavy rare earths – from a single operation.

Strategic context: growing geopolitical relevance

During the period, a US State Department delegation visited Sovereign’s facilities in Malawi. In January 2026, China tightened export licensing on heavy rare earths such as dysprosium, terbium and yttrium. Against that backdrop, Kasiya’s potential to supply rutile, graphite and monazite to western-aligned markets becomes more compelling. The Traxys MOU under the umbrella of Project Vault underlines this trend.

The good, the bad, and my take

• Positives: tangible DFS progress; IFC collaboration and potential financing involvement; Traxys MOU opening a commercial route for graphite; rare earth by-product discovery with attractive pricing signals; no debt and a solid cash balance to complete the DFS.
• Watch-outs: continued cash burn as DFS and project preparation continue; the offtake with Traxys is non-binding; rare earths upside is not yet quantified; net assets declined as cash was deployed.

Overall, this reads as a strategically stronger story than six months ago. If the DFS lands on time with robust economics, and the company converts MOU-level interest into binding offtakes and a financing plan with IFC and others, Kasiya could be well placed for the next step. The market will want to see concrete recovery data and scale for monazite, plus clarity on the graphite product mix between refractory and batteries.

What to watch next from Sovereign Metals

• Definitive Feasibility Study completion in the coming months, including integration of IFC Performance Standards.
• Updated Mineral Resource Estimate for Kasiya.
• Further offtaker updates for rutile and graphite, particularly US and allied-nation counterparties.
• Monazite characterisation, recovery rates and potential annual tonnage – the key to sizing the rare earths by-product stream.
• ESIA progress and infrastructure/logistics planning.

In short: more building blocks are dropping into place. Execution through DFS, binding sales, and project financing now take centre stage.
