Nimy Resources Reports High Gallium Extraction at Mons Block 3

Strong Metallurgical Results Highlight Processing Potential

Nimy Resources (ASX:NIM) has revealed promising metallurgical testwork from its Mons Project in Western Australia, reporting 84% extraction of gallium and between 80% to 95% recovery of rare earth elements (REEs) from its high-grade Block 3 mineralisation. These results provide a solid technical foundation for the company’s proprietary processing flowsheet, which is now central to ongoing optimisation and economic evaluation.

The Block 3 resource is among the highest-grade gallium deposits globally, with a maiden JORC Inferred Resource containing approximately 2,700 tonnes of gallium trioxide and 32,600 tonnes of total rare earth oxides at a 20g/t Ga2O3 cut-off. The metallurgical success supports Nimy’s ambition to supply critical minerals to Western markets amid rising geopolitical supply risks.

Proprietary IP and Collaborative Research Drive Development

Central to Nimy’s progress is a proprietary flowsheet developed specifically for the unique mineralogy of Block 3, representing valuable intellectual property. The company is advancing process optimisation through collaboration with Strategic Metallurgy, Curtin University, and the Mineral Research Institute of Western Australia (MRIWA). This partnership is tackling beneficiation, reagent optimisation, and hydrometallurgical extraction to enhance recoveries and refine the processing route.

Testwork has demonstrated that gallium and REEs can be efficiently recovered from leach solutions into a mixed intermediate product using conventional impurity removal and recovery techniques. Multiple alternative flowsheets are also under evaluation to potentially lower operating costs, improve recoveries, or simplify processing, all feeding into the ongoing Block 3 Scoping Study.

Strategic Importance Amid Global Supply Constraints

Gallium’s critical role in advanced semiconductors, defence technologies, and emerging power electronics has placed it under intense supply pressure, with China controlling up to 98% of global primary production. Recent export bans and licensing regimes have underscored the fragility of Western supply chains. Nimy’s high-grade, non-Chinese gallium resource at Mons offers a strategic alternative as demand accelerates, particularly in GaN power semiconductors forecast to grow nearly 27% annually through 2030.

The company’s resource remains open at depth and along strike, with exploration targets suggesting substantial upside potential. Concurrent soil sampling aims to identify additional high-grade gallium targets, while engagement with potential off-take partners continues to position Nimy within critical mineral supply discussions.

Next Steps in Project Advancement

Nimy plans to continue metallurgical characterisation across the weathering profile and advance beneficiation studies to determine optimal processing methods. The MRIWA-supported project will further refine gallium compound production and flowsheet optimisation. These activities, combined with the scoping study, will clarify the project’s economic viability and development pathways.

With the Mons Project situated in a Tier 1 mining jurisdiction and supported by a substantial tenement package, Nimy is methodically advancing its position in the critical minerals sector. The company’s approach reflects a blend of technical innovation and strategic market awareness, aiming to fill a crucial gap in Western gallium supply.
