KASIYA DEFINITIVE FEASIBILITY STUDY RESULTS

During the quarter, the Company announced the results of the Definitive Feasibility Study (DFS or the Study) for Kasiya. The DFS built on the outcomes of the Optimised Pre-feasibility Study announced in January 2025 and on empirical data from the Pilot Mining and Rehabilitation Program (Pilot Mining) completed in 2024. The DFS was undertaken in accordance with a scope of work approved by, and with technical input and oversight from, the Sovereign-Rio Tinto Technical Committee and, where applicable, conforms to the World Bank Group’s International Finance Corporation (IFC) Performance Standards to enhance bankability of the Project.

Following input from world-class consultancies, Sovereign’s highly experienced owners’ team, and subject matter experts from Rio Tinto, the DFS has reconfirmed that Kasiya will be a leading future supplier to two distinct strategic critical minerals supply chains and outside of Chinese control – natural rutile for the titanium industry and natural flake graphite.

Outstanding Financial Returns

The key financial metrics from the DFS (steady state, all on a 100% project basis) are set out below:

TABLE 1: Key DFS Metrics (Steady State)

Note: Steady State is defined as years of operation during which total run-of-mine is at full capacity of 24 Mtpa (i.e., years 5 to 23). All results are presented on a 100% project basis.

Summary of Key DFS Workstreams

Dry Mining Method Confirmed

Using real-world data collected from the Pilot Mining, the DFS confirms a dry mechanical mining method using draglines and 100t rigid dump trucks. The soft, free-dig saprolite orebody requires no drilling, blasting, crushing or milling. A two-bench approach (5m top cut, up to 15m bottom cut) keeps the draglines above the water table, eliminating the need for production equipment below groundwater level. This represents a significant de-risking step from the hydro-mining method originally considered in the original Pre-feasibility Study.

No Conventional Tailings Storage Facility

A major advancement in the DFS is the elimination of the conventional Tailings Storage Facility, leading to a significant reduction in the mining footprint and providing a flexible, lower-risk tailings management solution. All tailings will be stored via hydraulic co-disposal backfilling of mined-out pits, designed in compliance with the Global Industry Standard on Tailings Management. The 50:50 fines-to-sand backfill ratio closely matches the existing soil profile, supporting progressive rehabilitation.

Hydropower-Sourced Grid Electricity

The DFS is based on connection to Malawi’s national hydropower grid via a 132kV overhead line to the Nkhoma substation. Electricity Supply Corporation of Malawi Limited has confirmed significant grid expansion is underway, including a 400kV Mozambique interconnector and the 375MW IFC/World Bank-funded Mpatamanga hydropower station. Grid connection delivers substantially lower power costs and a favourable emissions profile.

Dual Plant Configuration and Processing Flowsheet

The DFS confirms a staged development with two 12Mtpa processing plants – South Plant from Year 1 and North Plant from Year 5 – positioned at the respective resource centres of gravity to minimise haulage distances and costs. The Wet Concentration Plant employs a low-energy gravity separation process to produce a Heavy Mineral Concentrate, which is then fed to the Mineral Separation Plant for electrostatic and magnetic separation to yield premium-quality rutile (+95% TiO₂). Graphite-rich concentrate recovered from the spirals is processed in a dedicated flotation plant, producing a high-purity, high-crystallinity, coarse-flake graphite product.

Logistics and Export Infrastructure

Kasiya’s products will be railed directly from a purpose-built dry port at the mine site eastward along the Nacala Logistics Corridor to the container terminal at the Port of Nacala on the Indian Ocean. The existing heavy-haul rail line and deep-water port provide a proven, operational export route – a significant infrastructure advantage over comparable undeveloped projects. Product transport cost is estimated at US$117/t product (FOB Nacala).

IFC Performance Standards Integrated into Design

The DFS has been prepared in alignment with IFC Performance Standards, with a comprehensive Environmental and Social Impact Assessment nearing completion and the full suite of environmental and social specialist studies completed. Sovereign’s established on-the-ground social team of 22 core staff and 90-member Community Liaison Team represent a level of social preparedness rarely achieved at DFS stage.

Heavy rare earth potential was not included in the DFS – evaluation of a monazite by-product from the rutile tailings stream continued during the quarter (see below).

SOVEREIGN TO ADVANCE KASIYA WITH US-FOCUSED CRITICAL MINERALS STRATEGY

With full responsibility for commercial, offtake and financing workstreams now with Sovereign, the Company is prioritising a US-focused critical minerals strategy. Kasiya is well placed to supply natural rutile and natural graphite to supply chains serving the US and allied economies, addressing acute gaps in secure, non-Chinese sources of critical minerals feedstock, alongside the potential heavy rare earth by-product opportunity.

Sovereign intends to progress existing rutile and graphite offtake arrangements, including those with Mitsui & Co., Ltd and Traxys North America LLC, from non-binding arrangements toward binding agreements, subject to negotiation. The Company will deepen engagement with the US Government, major US companies, industry stakeholders and development-finance institutions, and intends to pursue partnerships and financing arrangements with institutions across the US-allied economies, consistent with Kasiya’s role in securing critical minerals supply. The Company’s Collaboration Agreement with the IFC remains central to the Project’s financing strategy.

MONAZITE CONTAINING CRITICAL HEAVY RARE EARTHS CONFIRMED ACROSS MULTIPLE PITS

In May 2026, the Company announced significant heavy rare earth metallurgical testwork results at Kasiya. The testwork was conducted on monazite concentrates recovered from four pits in the Project’s DFS mine plan – Babbler, Kingfisher, Sparrow and Mousebird – including pits scheduled for Year 1 production.

The results confirm that the heavy rare earth content of Dysprosium (Dy), Terbium (Tb) and Yttrium (Y) first reported in January 2026 is present in pits scheduled for the early years of production at Kasiya, with average Total Rare Earth Oxide (TREO) basket ratios approximately 7x higher than the world’s five largest rare earth producers. Heavy rare earth content is highest in the near-surface (0-6m), which returns DyTb and Y ratios within the TREO basket materially above those of the deeper horizon.

TABLE 2: Summary Results (% of TREO basket)

Note: Kasiya Four-pit Average calculated as average of per-pit TREO basket ratios. See ASX Announcement dated 27 May 2026 “MONAZITE CONTAINING CRITICAL HEAVY RARE EARTHS CONFIRMED ACROSS MULTIPLE PITS AT KASIYA” – Appendix 1 and 2 for source details

Strategic Importance of Dysprosium-Terbium and Yttrium

Dy and Tb are heavy magnet rare earths essential for high-temperature permanent magnets used in advanced defence systems, precision weapons, aerospace applications and next-generation electric drivetrains. Y is a high-impact rare earth element critical for aerospace thermal barrier coatings, radar and laser systems, high-performance alloys and semiconductor manufacturing.

On 24 February 2026, the U.S. Assistant Secretary of War for Industrial Base Policy, Michael P. Cadenazzi Jr., testified before the Senate Armed Services Committee that on heavy rare earths China controls 95% of global output, with the U.S. importing almost 100% of what it uses – 90% of that from China – describing the situation as “a clear and present danger to our national security”. China’s April 2025 export controls on Dy, Tb and Y created immediate supply tightness for Western manufacturers, and on 6 January 2026 China announced strengthened export controls on dual-use items to Japan. The U.S. is 100% reliant on imports for its Y requirements, and MP Materials Corp., America’s only fully integrated rare earth producer, reports no measurable Dy, Tb or Y.

Western Supply-Chain Strategy: Market Context

The strategic value of non-Chinese heavy rare earth supply has been crystallised by recent corporate activity. On 20 April 2026, Nasdaq-listed USA Rare Earth, Inc. announced a definitive agreement to acquire Brazil’s Serra Verde Group for approximately US$2.8 billion, underpinned by a 15-year 100% U.S. Government-backed offtake agreement with contractual price floors of US$110/kg for both Neodymium and Praseodymium, US$575/kg for Dysprosium and US$2,050/kg for Terbium. On 20 January 2026, U.S. uranium and rare earth producer Energy Fuels Inc. announced a US$299 million acquisition of ASX-listed Australian Strategic Materials Limited.

These transactions crystallise the value that Western governments and capital markets now ascribe to scaled, non-Chinese rare earth supply. Kasiya’s monazite concentrate contains all four magnetic rare earth elements – plus Y – at TREO basket ratios consistent with or exceeding benchmark operations, potentially recovered as a by-product of a project that is already at DFS stage with a US$2.2 billion pre-tax NPV₈.

By-Product Economics: Near-Zero Incremental Cost

The monazite concentrates are recovered from the non-conductor tailings stream of the processing flowsheet specified in the Kasiya DFS – material that would otherwise report to tailings. Recovery as a by-product of the DFS-specified flowsheet could potentially mean no additional mining, no new primary processing circuits, no parallel rare-earth processing plant of the kind required by primary rare earth producers, and no additional reagents. In aggregate, monazite concentrate recovery is potentially achievable at near-zero incremental cost relative to the DFS base case. Further work is required to assess the capital and operating cost implications of any downstream product separation or refining, and to characterise the mineralogy, deportment, liberation and radioactive element (uranium and thorium) handling requirements of the Kasiya monazite.

Independent Price Forecast

Project Blue Group Limited (Project Blue), a specialist in critical minerals market intelligence, prepared an independent price forecast for a monazite mineral concentrate containing 60% TREO with a distribution in line with that observed in Sovereign’s testwork to date. Project Blue’s 2026 base-case forecast is US$16,000/t (high case US$19,000/t), against the April 2026 Shanghai Metals Market benchmark monazite concentrate (54-55% TREO grade) price of approximately US$6,142/t. Project Blue notes that prices for key rare earth products are commanding a premium in ex-China markets, reflecting the limited pool of non-Chinese suppliers and the ongoing decoupling of Western and Chinese rare earth supply chains.

Sovereign has not entered into any offtake or sales agreement for monazite concentrate. Realised prices will depend on commercial negotiation, market conditions at the time of sale, the actual specifications of any concentrate produced and the terms of any offtake agreement.

SUCCESSFUL REHABILITATION TRIALS AND COMMUNITY PARTNERSHIPS

In April 2026, the Company announced that its second year of rehabilitation trials, as part of the Pilot Mining at Kasiya, was nearing completion for the upcoming harvest season in Malawi. The rehabilitation trials provide practical, multi-year evidence demonstrating Sovereign’s alignment with international rehabilitation, environmental, and community good-practice standards. Empirical data from the trials were used to prepare the Mine Closure and Mine Rehabilitation Plans, which are now integrated into the mining, backfilling and post-mining closure planning – critical components for project bankability and alignment with the standards required by development finance institutions.

The second year of trials builds on the success of the first year, which delivered maize yields of 5.2 tonnes per hectare versus the regional average of 1 tonne per hectare – a fivefold increase that confirmed post-mining land can achieve superior agricultural productivity compared to pre-mining land. Second-year crop yields are expected to reach the first-year benchmark when harvested in mid-2026. The second year expanded the rehabilitation approach into a diversified multi-cropping system, combining maize with Giant Bamboo, winter beans, grass fodder and groundnuts, providing participating communities with a wider range of food, cash and fodder crops.

After two years of close collaboration, the 28 local farmers involved in the trials formally requested that Sovereign remain at the trial site and support them in establishing a farming co-operative. This represents a strong community endorsement of the program’s value and is a central pillar of Kasiya’s post-closure social transition strategy, demonstrating that the Project can deliver lasting economic benefits to local communities well beyond the mine life. The outcomes directly complement the collaboration with the IFC, which is supporting integration of IFC Performance Standards into the Project’s Environmental and Social Impact Assessment, and strengthening Kasiya’s pathway to bankable development and international project financing.

KASIYA DEFINITIVE FEASIBILITY STUDY RESULTS

During the quarter, the Company announced the results of the Definitive Feasibility Study (DFS or the Study) for Kasiya. The DFS built on the outcomes of the Optimised Pre-feasibility Study announced in January 2025 and on empirical data from the Pilot Mining and Rehabilitation Program (Pilot Mining) completed in 2024. The DFS was undertaken in accordance with a scope of work approved by, and with technical input and oversight from, the Sovereign-Rio Tinto Technical Committee and, where applicable, conforms to the World Bank Group’s International Finance Corporation (IFC) Performance Standards to enhance bankability of the Project.

Note: Steady State is defined as years of operation during which total run-of-mine is at full capacity of 24 Mtpa (i.e., years 5 to 23). All results are presented on a 100% project basis.

Summary of Key DFS Workstreams

Dry Mining Method Confirmed

Using real-world data collected from the Pilot Mining, the DFS confirms a dry mechanical mining method using draglines and 100t rigid dump trucks. The soft, free-dig saprolite orebody requires no drilling, blasting, crushing or milling. A two-bench approach (5m top cut, up to 15m bottom cut) keeps the draglines above the water table, eliminating the need for production equipment below groundwater level. This represents a significant de-risking step from the hydro-mining method originally considered in the original Pre-feasibility Study.

The DFS has been prepared in alignment with IFC Performance Standards, with a comprehensive Environmental and Social Impact Assessment nearing completion and the full suite of environmental and social specialist studies completed. Sovereign’s established on-the-ground social team of 22 core staff and 90-member Community Liaison Team represent a level of social preparedness rarely achieved at DFS stage.

Heavy rare earth potential was not included in the DFS – evaluation of a monazite by-product from the rutile tailings stream continued during the quarter (see below).

SOVEREIGN TO ADVANCE KASIYA WITH US-FOCUSED CRITICAL MINERALS STRATEGY

With full responsibility for commercial, offtake and financing workstreams now with Sovereign, the Company is prioritising a US-focused critical minerals strategy. Kasiya is well placed to supply natural rutile and natural graphite to supply chains serving the US and allied economies, addressing acute gaps in secure, non-Chinese sources of critical minerals feedstock, alongside the potential heavy rare earth by-product opportunity.

The Company will deepen engagement with the US Government, major US companies, industry stakeholders and development-finance institutions, and intends to pursue partnerships and financing arrangements with institutions across the US-allied economies, consistent with Kasiya’s role in securing critical minerals supply. The Company’s Collaboration Agreement with the IFC remains central to the Project’s financing strategy.

MONAZITE CONTAINING CRITICAL HEAVY RARE EARTHS CONFIRMED ACROSS MULTIPLE PITS

In May 2026, the Company announced significant heavy rare earth metallurgical testwork results at Kasiya. The testwork was conducted on monazite concentrates recovered from four pits in the Project’s DFS mine plan – Babbler, Kingfisher, Sparrow and Mousebird – including pits scheduled for Year 1 production.

The results confirm that the heavy rare earth content of Dysprosium (Dy), Terbium (Tb) and Yttrium (Y) first reported in January 2026 is present in pits scheduled for the early years of production at Kasiya, with average Total Rare Earth Oxide (TREO) basket ratios approximately 7x higher than the world’s five largest rare earth producers. Heavy rare earth content is highest in the near-surface (0-6m), which returns DyTb and Y ratios within the TREO basket materially above those of the deeper horizon.

China’s April 2025 export controls on Dy, Tb and Y created immediate supply tightness for Western manufacturers, and on 6 January 2026 China announced strengthened export controls on dual-use items to Japan. The U.S. is 100% reliant on imports for its Y requirements, and MP Materials Corp., America’s only fully integrated rare earth producer, reports no measurable Dy, Tb or Y.

Western Supply-Chain Strategy: Market Context

The strategic value of non-Chinese heavy rare earth supply has been crystallised by recent corporate activity. On 20 April 2026, Nasdaq-listed USA Rare Earth, Inc. announced a definitive agreement to acquire Brazil’s Serra Verde Group for approximately US$2.8 billion, underpinned by a 15-year 100% U.S. Government-backed offtake agreement with contractual price floors of US$110/kg for both Neodymium and Praseodymium, US$575/kg for Dysprosium and US$2,050/kg for Terbium. On 20 January 2026, U.S. uranium and rare earth producer Energy Fuels Inc. announced a US$299 million acquisition of ASX-listed Australian Strategic Materials Limited.

These transactions crystallise the value that Western governments and capital markets now ascribe to scaled, non-Chinese rare earth supply. Kasiya’s monazite concentrate contains all four magnetic rare earth elements – plus Y – at TREO basket ratios consistent with or exceeding benchmark operations, potentially recovered as a by-product of a project that is already at DFS stage with a US$2.2 billion pre-tax NPV₈.

By-Product Economics: Near-Zero Incremental Cost

The monazite concentrates are recovered from the non-conductor tailings stream of the processing flowsheet specified in the Kasiya DFS – material that would otherwise report to tailings. Recovery as a by-product of the DFS-specified flowsheet could potentially mean no additional mining, no new primary processing circuits, no parallel rare-earth processing plant of the kind required by primary rare earth producers, and no additional reagents. In aggregate, monazite concentrate recovery is potentially achievable at near-zero incremental cost relative to the DFS base case. Further work is required to assess the capital and operating cost implications of any downstream product separation or refining, and to characterise the mineralogy, deportment, liberation and radioactive element (uranium and thorium) handling requirements of the Kasiya monazite.

Independent Price Forecast

Project Blue Group Limited (Project Blue), a specialist in critical minerals market intelligence, prepared an independent price forecast for a monazite mineral concentrate containing 60% TREO with a distribution in line with that observed in Sovereign’s testwork to date. Project Blue’s 2026 base-case forecast is US$16,000/t (high case US$19,000/t), against the April 2026 Shanghai Metals Market benchmark monazite concentrate (54-55% TREO grade) price of approximately US$6,142/t. Project Blue notes that prices for key rare earth products are commanding a premium in ex-China markets, reflecting the limited pool of non-Chinese suppliers and the ongoing decoupling of Western and Chinese rare earth supply chains.

Sovereign has not entered into any offtake or sales agreement for monazite concentrate. Realised prices will depend on commercial negotiation, market conditions at the time of sale, the actual specifications of any concentrate produced and the terms of any offtake agreement.

SUCCESSFUL REHABILITATION TRIALS AND COMMUNITY PARTNERSHIPS

In April 2026, the Company announced that its second year of rehabilitation trials, as part of the Pilot Mining at Kasiya, was nearing completion for the upcoming harvest season in Malawi. The rehabilitation trials provide practical, multi-year evidence demonstrating Sovereign’s alignment with international rehabilitation, environmental, and community good-practice standards. Empirical data from the trials were used to prepare the Mine Closure and Mine Rehabilitation Plans, which are now integrated into the mining, backfilling and post-mining closure planning – critical components for project bankability and alignment with the standards required by development finance institutions.

The second year of trials builds on the success of the first year, which delivered maize yields of 5.2 tonnes per hectare versus the regional average of 1 tonne per hectare – a fivefold increase that confirmed post-mining land can achieve superior agricultural productivity compared to pre-mining land. Second-year crop yields are expected to reach the first-year benchmark when harvested in mid-2026. The second year expanded the rehabilitation approach into a diversified multi-cropping system, combining maize with Giant Bamboo, winter beans, grass fodder and groundnuts, providing participating communities with a wider range of food, cash and fodder crops.

After two years of close collaboration, the 28 local farmers involved in the trials formally requested that Sovereign remain at the trial site and support them in establishing a farming co-operative. This represents a strong community endorsement of the program’s value and is a central pillar of Kasiya’s post-closure social transition strategy, demonstrating that the Project can deliver lasting economic benefits to local communities well beyond the mine life. The outcomes directly complement the collaboration with the IFC, which is supporting integration of IFC Performance Standards into the Project’s Environmental and Social Impact Assessment, and strengthening Kasiya’s pathway to bankable development and international project financing.
