Managing Director Frank Eagar commented: "Advancing to a Pilot Phase is an important milestone for Kasiya. This covers the full spectrum of engineering and design, logistics, materials handling, water and environmental approvals, stakeholder engagement, livelihood restoration, tailings management and land rehabilitation. The successful permitting is a testament to the strong owner's team we have assembled. We are progressing Kasiya into a totally new phase of development. The scale and results from this phase will significantly enhance our knowledge base from the previous laboratory-based studies. I want to thank the Malawi Government for an efficient approvals process, demonstrating just how important Kasiya is to all stakeholders."

Classification 2.2: This announcement includes Inside Information

Sovereign Metals Limited (ASX:SVM; AIM:SVML) (the Company or Sovereign) is pleased to announce that the Company has initiated a Pilot Mining and Land Rehabilitation Program at its Kasiya Rutile-Graphite Project (Kasiya or Project) in Malawi.

The results will allow Sovereign to determine optimal excavation, backfill and land rehabilitation approaches. The Pilot Phase will be a demonstration to local communities of the successful rehabilitation of land for agricultural use post-mining. Results will also provide critical information for the upcoming Definitive Feasibility Study (DFS) and once commenced, it will shorten the time to its completion.

The objectives of the Pilot Phase include:

· Optimisation of mining methods by construction of a pilot-scale open pit close to the maximum depth of the current reserves at 20m;

· Scale-up of existing in-country processing capability by installation of commercial scale spirals to produce additional bulk samples for graphite product qualification;

· Optimising the tailings management and storage designs; and

· Optimising land rehabilitation, soil restoration and selection of revegetation species.

The commencement of the Pilot Phase follows the receipt within three months of all relevant approvals and permissions from the Malawi Environment Protection Authority (MEPA), National Water Resources Authority (NWRA), the Ministry of Mines, and the local community.

The Pilot Phase will be undertaken on a 9.9-hectare site and will include the following activities:

1. Test Pit: A test pit of 120m by 110m will be excavated to a depth of 20m, allowing optimisation of hydraulic and dry mining excavation methods.

2. Stockpiles: The excavated material will be temporarily stored in 4 stockpiles, namely all dry mining material, wet slimes (in a pond) and two sizes of sand fractions from the hydraulic mining.

3. Backfilling and Grading: The material will be placed back into the pit, and all areas will be graded.

4. Rehabilitation Demonstration: Sovereign will construct eight small rehabilitation demonstration pits covering a combined area of 100m by 130m. These will be used for water storage, excavated material storage, and demonstration of multiple rehabilitation approaches.

5. Temporary Laydown Areas: Four areas will be used as temporary laydown areas, offices, and associated infrastructure.

6. Communication: The Pilot Phase will be an educational opportunity for Project stakeholders. Sovereign will undertake a series of stakeholder visits and consultations for this purpose.

Kasiya is the world's largest natural rutile deposit and the second-largest flake graphite deposit. Sovereign aims to develop a low-CO2 and sustainable operation to supply highly sought-after natural rutile and graphite to global markets.

Results of the PFS, released in late 2023, demonstrated Kasiya's potential to become the world's largest rutile producer at 222kt per annum and one of the world's largest natural graphite producers (ex-China) at 244kt per annum.

The PFS delivered compelling economics with a post-tax NPV8 of US$1.6 Billion and a post-tax IRR of 28%. This long-life, multi-generational operation generates over US$16 Billion of revenue based on an initial 25-year life-of-mine and delivers an average annual EBITDA of US$415 Million per annum.

Pilot Phase Program Design

Activities have been designed to establish a 9.9-hectare site over the current Ore Reserve defined in the Kasiya PFS, covering a mineralised zone with soil conditions deemed representative of the overall Mineral Resource Estimate (MRE). Over approximately three months, Sovereign will excavate several test pits and collect geological and geotechnical samples. The main pit will be backfilled with dry material, while material from hydraulic mining will be used to fill the remaining pits as part of the rehabilitation phase.

Land rehabilitation will form an integral component of the DFS. Sovereign's objective is to restore land after mining to conditions that achieve the same or better agricultural yields than existing land uses and crop yields. For this reason, the Company will undertake field-based demonstrations of rehabilitation showcasing drying times, soil recoveries, soil nutrients, growth variants, and including different soil inputs and revegetation methods.

Site Construction

Prior to the establishment of site infrastructure, eight boreholes have been permitted and drilled using a locally appointed drilling contractor. These boreholes will supply water to the site, which will be stored in a temporary water storage pond.

A perimeter fence will be erected around the site to maintain the necessary health and safety standards. Existing roads will be used for access to the site and, if required, improved through grading.

Temporary buildings such as offices and stores will be brought to the site on flatbed lorries and erected. To support pilot mining, two 1MW mobile diesel-powered electricity generators will be installed to provide the electricity required for high-pressure water monitors.

Pilot Mining

The main pit will be excavated using conventional load and haul to 20m depth to develop a sump to test hydraulic mining to the full depth of the current Ore Reserves. The excavated material will be temporarily stored in stockpiles.

On-Site Processing Facility

Material mined from the test pit will be processed on-site and at the Company's laboratory facility in Lilongwe. As previously announced (Please refer to announcement dated 1 May 2024 entitled "Sovereign to Increase Bulk Sample Preparation Capacity"), as part of the Pilot Phase, a commercial-scale spiral plant will be installed at site in Malawi.

Rutile and graphite concentrate samples generated from the Pilot Phase will be shared with potential off-takers and end-users, and used for further testwork as part of the Company's graphite commercialisation strategy.

Rehabilitation Phase

This phase will consist of establishing a strong soils baseline, backfilling of the test pit with different soil compositions, rehabilitation tests, revegetation with plants, and the improvement of soil conditions post-mining.

Regular monitoring and evaluation of the rehabilitation activities will be undertaken to assess the progress of vegetation growth and soil stabilisation. Following the conclusion of the rehabilitation, the proposed project site will be returned to farmland.

Permitting

Permissions for the Pilot Phase were received following the successful submission of an Environmental and Social Management Plan to MEPA. Sovereign is committed to the responsible development of Kasiya. The Pilot Phase will be undertaken in accordance with Malawian Law and IFC Performance Standards, which will include protecting local communities and the natural environment.
