Harena Resources plc Reports Pre-Feasibility Study Work Is Progressing At Accelerating At Accelerating At Accelerating At Acceleration on Its 75% Owned Ampasindava Rare Earths Project in Madagascar Harena Resources Plc reported that Pre-Feasibility study work is progressing at pace on its 75% owned Ampaindava Rare Earths Project in Madagascar. Initial work on the mining plan is well advanced and will underpin subsequent cost and logistics modelling ahead of the next phase of project development. The urgency of this work is reinforced by escalating geopolitical tensions and export controls around critical rare earth elements ("REEs"). This has sharpened international focus on securing independent supply specifically of strategically important critical magnet metals Neodymium (Nd), Praseodymium (Pr), Dysprosium (Dy) and Terbium (Tb). This study work is the critical path item towards achieving the Company's goal of developing an environmentally responsible, and geopolitically neutral supply of magnet metals to feed the global defence, energy, and technology sectors and forms the foundation for progressing a full Mining Licence application under the 2023 Madagascar Mining Code - a key milestone toward near-term development. Highlights: Mining Study underway following integration of extensive historical geological and resource data. Pre-Feasibility Study (PFS) on track for submission to the Mining Cadastre Office ("BCMM") in third quarter 2025. Project Design philosophy completed - focused on near-surface high-grade zones, reagent efficiency, and low-impact processing. Study incorporates all prior Exploration, Metallurgical and Mineral Resource results compiled by SGS Canada, assessed against working plan for open cut, heap leach processing operation. Onsite environmental and social screening work to commence with appointment of a Malagasy consultant. Appointment of the Environmental Project Lead is planned for late May 2025. The Pre-Feasibility study is progressing well and submission is planned for submission to the Mining CadASTre Office (BCMM) during the third quarter 2025 The Project design philosophy is underpinned by the large, shallow and highly accessible rare earth mineral deposit held in the upper regolith layer. The first pillar of design is to mine high grade and high ore thickness areas during the first 10 years of extraction. Initial mining studies indicate the clays can be mined with minimal grade dilution. In addition, the Resource indicates that large areas of higher grade are discretely placed throughout the mining areas. The third pillar of process design is to be achieved through further metallurgical testing at an on-site demonstration plant to be constructed following transition of the mining license. The higher value rare earth minerals will be prioritised in preference to low value products Environmental Approach Madagascar lies within a diverse ecological and environmental setting. The Company has no plans or intention to proceed with a strategy that may compromise the environmental baseline. The current plan is a system of cyclical, zero harm mining and concurrent rehabilitation as commonly undertaken in the mineral sands industry. Clays will be returned to the mining cavity on an ongoing basis and stored top-soil will be replaced facilitating immediate natural rehabilitation or repurpose for agriculture. Leaching with a dedicated and ring-fenced heap leach farm will be conducted with Ammonium Sulphate (fertiliser) lixiviant onto impermeable heap foundations. The Company should not require any strong acids as part of the primary mineral recovery system. Logistics Project logistics on the Madagascar mainland is complex as a result of an underdeveloped road transport system. In order to reduce capital and operating costs and improve efficiency, seaborne and airborne logistics will be prioritised over land-based transport. The plant and equipment to be installed is expected to consist of modular units. It is planned that the majority of the equipment will be transported in standard 20ft or 40ft containers. The island of Nosy B hosts an international airport and is located just 35km from the mine site, by sea. The logistics study is a key element of the project viability with the proximity to the ocean viewed as a significant benefit to the project. Announcement • Apr 16
Harena Resources plc Reports Metallurgical Test Results from Its 75% Owned Ampasindava Rare Earths Project in Madagascar Harena reported metallurgical test results from its 75% owned Ampaindava Rare Earths Project in Madagascar. The work confirms that ionic clay-hosted rare earth elements from Ampaindava - including the strategically critical magnet metals Neodymium (Nd), Praseodymium (Pr), Dysprosium (Dy) and Terbium (Tb) - can be recovered efficiently using low-impact heap leach processes such as salt water or standard ammonium sulphate solutions. This result supports the Company's goal of developing a technically robust, environmentally responsible, and geopolitically independent supply of magnet metals essential to the global defence, energy, and technology sectors. REEs at Ampaindava are readily recoverable through simple ion desorption, with high extraction rates achieved using a ammonium sulphate leach in low-acid conditions. Main extractions were approximately 88% Nd, 73% Dy, 67% Y, 86% La, with low levels of gangue, thorium (Th) and uranium (U) supporting a clean environmental profile. SGS Lakefield testwork using a pH 5 ammonium sulphate solution delivered strong results, including 87% Nd, 88% Pr, 71% Dy, 75% Tb and 63% Y Encouragingly optimal column heap leach test, over 218 hours, demonstrated recoveries of 88% Nd, 86% Pr, 73% Dy, 79% Tb and 67% Y using Ammonium Sulphate at a pH of 4. Low value/high bulk Cerium demonstrated minimal recovery, a significant benefit in production of a high-grade magnet metal concentrates or carbonates. Summary of Key Technical Information Metallurgical test work was carried out on 54 bulk and discrete samples of the regolith clays over several campaigns by the University of Toronto, Outotec and SGS Lakefield. The SGS Lakefield samples were sourced from test pits and were taken between 1m and 10m below surface and weighed between 6kg and 35kg each. Some were used separately and others amalgamated into several representative bulk samples including a Master Clay Composite. The testing culminated in 12 optimum eluant tests and follow on column tests for the use of salt water or ammonium sulphate as primary leaching agent. Announcement • Mar 31
Harena Provides an Update on the Ampasindava Rare Earths Project in North-Eastern Madagascar Harena provided an update on the Ampaindava Rare Earths Project ("Project") in north-eastern Madagascar. Following a detailed review of historic exploration data that formed the basis for the current Mineral Resources Estimate ("MRE") of 698.5 million tonnes measured, indicated and inferred JORC 2012 compliant Resource reported on 1 November 2023 by SGS (and incorporated in the Company's prospectus dated 26 February 2025), the Company has identified significant high-grade rare earth zones. The MRE supports a potential mine-life of over one hundred years. This potential longevity creates flexibility in mine planning and the opportunity to target high grade zones during critical start up years. This forms part of the Company's strategy to enhance near-term project economics and cash flow generation. The Company's technical team has review all available historic exploration data from trenching, sinking vertical pits, and 277 diamond drill holes. This work confirms the potential for early stage high-grade mining operations and mine plan optimisation. Additionally, the advanced level of exploration and feasibility work already completed on the Project, presents further opportunities for to optimise mine planning optimisation across the ionic clay rare earth element ("REE") deposit. Samples were collected from the lowermost interval first to minimise contamination. All of the pits were back-filled as soon as geological observations, density measurements, moisture readings and sampling were completed. The lithology identified within the Ionic Clay regolith zone are an upper zone of pedolith overlying a saprolith hosting saprolite and the transition to saprock. Notable amongst these results are the Max results for the Pedolith of 14,999 ppm TREO and for the Saprolith of 39,098 ppm TREO indicating that the mineralisation is skewed towards the saprolite layer, closer to the underlying volcanic breccia. The very low minimums found in some pits indicates that some were excavated in clays which sit outside the volcanic breccia providing the REE feedstock. This diverse range of minimums and highs is not present in the trenching results. These results, while still to be tested, provide flexibility in mining and targeting higher grade material for the planned initial heap leach production. However, it should be noted that this is too small a dataset on which to make definitive conclusions and warrants further follow up work. Summary of the Trench Sample Results (Gilbertson 2013) Block Model TREO values In developing a 3D Block Model for the Resource, the modeller determined the area of the Resource that hosted grades of between 1,000 ppm TREO and 2,000 ppm TREO. As can be observed in the image below, these extensive areas are contiguous to the east of the resource and whilst a mining reserve has not yet been determined, it is clear that an initial focus on the red areas, if possible, will provide a mining grade higher than the published resource grade.
