March 2025 Quarterly Report

Sovereign Metals Limited (ASX:SVM, AIM:SVML, OTCQX:SVMLF) (Sovereign or the Company) is pleased to provide its quarterly report for the period ended 31 March 2025.

HIGHLIGHTS DURING AND SUBSEQUENT TO THE QUARTER

Optimised PFS Results Reaffirm Kasiya's Globally Strategic Significance

• In January 2025, the Optimised Prefeasibility Study (OPFS) was completed with oversight from the Sovereign-Rio Tinto Technical Committee. Results of the OPFS reaffirmed Kasiya's potential to become one of the largest and lowest-cost producer of natural rutile and natural flake graphite while generating exceptional economics
• Various optimisations have led to superior project delivery, operational flexibility, environmental and social outcomes compared to the 2023 Prefeasibility Study (PFS)

Successful Rehabilitation of Kasiya Test Pit

• During the quarter, rehabilitation of the land at the test pit site mined during the Pilot Mining and Land Rehabilitation (Pilot Phase) substantially progressed. Site backfill completed and soil remediation work concluded in December 2024, with landowners accessing the site through to January 2025 to plant and cultivate crops without missing a planting season

Kasiya Graphite Suitable for >94% of End-Use Markets

• Test work completed during the quarter has demonstrated that Kasiya graphite is suitable for use in the three key segments that account for over 94% of the ~1.6Mtpa global demand for natural flake graphite-battery anodes, refractories and expanded/expandables
• Sovereign intends to produce a 96% graphite concentrate at an incremental cost of US$241/t (FOB)

DFS Geotechnical Programs in Progress

• Subsequent to the quarter, the Company announced that extensive geotechnical investigations are underway at key project infrastructure locations across Sovereign's Kasiya Project. Results will support layout and engineering design for the Kasiya Definitive Feasibility Study (DFS)which is due Q4 2025

Next Steps

• Over the course of the quarter ending June 2025, Sovereign will continue to advance the DFS, publish an upgrade to the Mineral Resource Estimate (MRE), continue with further graphite testwork and graphite offtake discussions, and further its community and social development programs in Malawi.

During the quarter, the Company announced the results of an OPFS for its Kasiya Rutile-Graphite Project (Kasiya or the Project) which was undertaken following a strategic investment by Rio Tinto Mining and Exploration Limited (Rio Tinto) in 2023. Under the Investment Agreement, a joint Technical Committee was established to oversee the development of Kasiya. The OPFS was conducted with oversight from the Sovereign-Rio Tinto Technical Committee.

The OPFS proposes a large-scale, long-life operation to deliver substantial volumes of natural rutile and graphite while generating significant returns. Table 1 below summarises the key findings from the OPFS and includes a comparison to the PFS results released 16 months ago, in September 2023.

It is important to note that the results for the 2023 PFS in Table 1 have not been updated or adjusted for inflation since their release.

TABLE 1: KEY OPFS METRICS

*Annual average graphite produced includes 292kt of graphite processed and sold in two years post cessation of active ore mining. Average graphite produced during the 25-year initial mine life only is 240ktpa; total revenue during the same period is US$15,990 million. All rutile is produced and sold during the 25-year initial mine life. Note: All cashflows and costs are presented in US$ real January 2025 terms unless otherwise stated. Operating costs exclude mineral royalties and community development support costs.

Summary of Optimisations

The OPFS optimises seven key areas compared to the 2023 PFS, as summarised below.

Mining Method

The PFS proposed a 25-year initial LOM based on a hydraulic mining process where slurry material would be screened and pumped overland to the processing plants.

Operating Model

The 2023 PFS envisaged mining would take place on a contractor basis.

During the OPFS, Sovereign undertook a trade-off analysis between the following operating options:

• Fully owner-operated mine with draglines and trucks purchased by the owner
• Owner-operated mine with draglines and trucks leased by the owner
• Mining contractor operation using excavators and trucks

Plant Configuration

Plant Location

Tailings Management

Water Management

The PFS proposed that the primary water supply for the Kasiya mining complex would be created by building a water storage dam and collecting run-off water from the greater catchment area. Following the introduction of dry mining and mud farming, the size of the water storage dam proposed in the PFS has been significantly reduced, with less process water required and more process water recovered.

The OPFS mining trials and material deposition tests indicated a water demand of 10.2 Mm³ per annum, almost a 40% decrease in water requirement from the PFS (16.7 Mm³). The effect on the water storage dam wall could be a reduction in volume from 0.79 Mm³ to 0.57 Mm³ and a reduction in dam wall height from 20 metres to 17 metres.

Power

The 2023 PFS envisaged a hybrid hydro-generated grid power plus solar power system solution.

Successful Rehabilitation of Kasiya Test Pit

In March 2025, the Company announced that the rehabilitation of the land at the test pit mined during the Pilot Phase has been substantially progressed. Soils remediation work was concluded in December 2024 with landowners accessing the site between December 2024 and January 2025 to plant and cultivate crops without missing a planting season.

All soil remediation works as well as planting was done by hand with the use of a grader and tractor to prepare the soils. Sovereign employed the local landowners to work with us in both the soil remediation and planting work, so they were able to directly experience and learn about our rehabilitation work on their land.

Sovereign is working closely with the landowners to ensure that the crops provide a good yield in 2025, while simultaneously testing a variety of rehabilitation crops. This includes the intercropping of giant bamboo with maize, which will be retained by the landowners.

Sovereign is committed to ensuring that all mined-out land is appropriately rehabilitated to support sustainable farming practices after closure. The soil remediation methods aim to revitalise the soils within a two-to-three-year timeframe and to ensure that soils can be sustainably farmed in the long term. The remediation of soil to a depth of 1 metre from surface, will ensure the land can support small-scale or full-commercial farming operations.

Kasiya Graphite Suitable for >94% of End-Use Markets

In February 2025, the Company announced that downstream testwork completed on graphite from Kasiya confirmed that Kasiya's graphite has the key characteristics required for use in refractory applications.

Graphite's key properties for use in refractory applications are its resistance to oxidation, chemical inertness and good thermal conductivity.

Graphite products for refractory applications typically require larger flake sizes than the smaller graphite flake products used to produce battery anode materials. Larger flake size graphite products tend to attract significantly higher prices than smaller flake products.

During the same month, Sovereign announced that further testwork confirmed that Kasiya graphite has the key characteristics required for use in expandable (fire retardant) and expanded (gaskets, seal, and brake lining) applications.

Sovereign had previously announced in 2024 that Kasiya graphite had produced outstanding battery anode material. Together with the refractories and expanded/expandables market, Kasiya's graphite is suitable for over 94% of end-use markets.

In Q4 2024, Syrah Resources Limited (the world's largest, publicly listed natural graphite producer outside of China) reported a price for smaller flake graphite concentrate to be used for battery anode production of US$564 per tonne (CIF) based on third-party sales. In December 2024, large flake graphite used in the refractory sector achieved prices of up to US$1,193/t (based on data from Benchmark Mineral Intelligence).

The incremental cost of producing a tonne of graphite from Kasiya under Sovereign's recently announced Optimised Prefeasibility Study is US$241/t (see announcement "Kasiya - Optimised PFS Results" dated 22 January 2025) making Kasiya the only advanced graphite project capable of competing with current Chinese graphite production costs.

DFS Geotechnical Programs in Progress

In April 2025 and subsequent to the quarter, the Company announced that several geotechnical drilling programs are underway at Kasiya as part of the DFS. The results of the programs will be used to support the infrastructure layout and engineering design.

Selected locations are based on the findings of the OPFS announced in January 2025. The OPFS proposes a large-scale, long-life operation to deliver substantial volumes of natural rutile and graphite while generating significant returns. The Project layout was determined by evaluating technical, environmental and social factors.

Infrastructure covered by the geotechnical programs includes the processing plant areas, the tailings storage facility (TSF) area, the raw water storage dam, the Kasiya substation, and other mining infrastructure. Various geotechnical and geophysics methods are being used across the project site area.

Placement and Corporate Update

In March 2025, Sovereign completed a placement of 47,058,824 new fully paid ordinary shares at an issue price of A$0.85 to raise gross proceeds of A$40 million (Placement). Following the Placement, Sovereign has over A$65 million in cash and no debt.

To date, Rio Tinto has invested A$60 million into Sovereign to fund completion of the DFS. The DFS is expected to be completed in Q4 2025, thereby providing Rio Tinto with up to 180 days to exercise its option to become operator of the Kasiya Project. Rio Tinto did not participate in the Placement as they believe the Company has sufficient funds to complete the Kasiya DFS.

Accordingly, Rio Tinto's shareholding in Sovereign remains at approximately 119.4 million shares. Due to the issuance of new shares under the Placement, Rio Tinto's relative shareholding has decreased from 19.9% to 18.5% (refer to change in substantial holding notice dated 4 April 2025).

Rio Tinto, via the joint Sovereign-Rio Tinto Technical Committee, continues to be supportive of the Project and, as a strategic investor, continues to play an integral part in the Kasiya DFS process, including site visits, project environmental and social workstreams, with their subject matter experts involved in numerous aspects of the Project.

As discussed above, the Kasiya DFS remains on track for completion in Q4 2025. Upon announcement of the DFS results and under the July 2023 Investment Agreement, Rio Tinto will have up to 180 days to exercise its option to become the operator of the Kasiya Project and be granted exclusive marketing rights for 40% of Kasiya's annual production.

Next Steps

The Company plans to update the market on the following progress in the coming months:

• Rehabilitation component of the Pilot Phase
• MRE upgrade following 2024 infill drilling program
• Further graphite test work results as the Company continues to advance the qualification of its graphite product for the lithium-ion battery and traditional graphite sectors
• Progress in discussions with future potential end-users of rutile and graphite
• Updates on community and social development programs
• Progress of the DFS, which is targeted for completion by Q4, 2025
