Nimy Resources Expands Mons Gallium Resource with US Test Shipment Underway

Significant Gallium Extensions at Mons Block 3

Nimy Resources (ASX:NIM) has revealed a substantial expansion potential at its Mons Gallium Block 3 deposit in Western Australia. A high-resolution magnetic survey indicates the gallium-bearing host unit extends 3.5 kilometres beyond the current 400-metre-wide JORC Inferred Resource corridor, which contains 2,700 tonnes of gallium trioxide at a 20g/t cut-off. The deposit remains open both along strike and at depth, with current estimates only accounting for oxide and transition zones to about 100 metres depth. Exploration targets at Block 3 alone suggest a conceptual total of 26 million tonnes at 100g/t Ga2O3 and 100 million tonnes at 810ppm total rare earth oxides (TREO), although these remain unclassified and require further drilling and evaluation.

This sizeable extension aligns with prior announcements of gallium growth potential, reinforcing the Mons Project's standing as a major critical minerals prospect in Western Australia. The company is actively designing a drill program to test these extensions and deepen the resource base, aiming to convert exploration targets into formal resources. The recent magnetic survey and resource data form the backbone of this expansion strategy, highlighting the district-scale potential of the Mons Belt.

US Shipment Advances Processing and Supply Chain Security

In a strategic move to secure Western supply chains for critical minerals, Nimy has shipped its first high-grade gallium mineralised test material from Western Australia to the United States under a collaboration agreement with US-listed M2i Global. This shipment marks a key milestone in developing processing pathways tailored to US defence and national security needs. The material will undergo metallurgical analysis by academic institutions and defence industry partners to determine optimal refining processes for commercial-grade gallium products.

This collaboration supports the broader Australia-US critical minerals framework established in late 2025 and aligns with Nimy’s participation in the recent Western Australian critical minerals delegation to the US, led by Mines and Petroleum Minister David Michael. Managing Director Luke Hampson led Nimy’s engagement with financiers and potential offtake partners in New York and Washington DC, aiming to strengthen trade ties and secure market access for Mons gallium products. The company’s efforts build on prior shipments and strategic presentations, underscoring its commitment to becoming a reliable supplier in the growing critical minerals sector.

Scoping Study and Metallurgical Test Work Progress

Nimy has commissioned Perth-based Strategic Metallurgy to conduct a scoping study on the Block 3 resource, assessing mining, processing, capital costs, and preliminary economics. Metallurgical test work is underway to develop a pathway for producing high-grade gallium concentrate, with results expected to feed into the study during the June quarter. This work is critical to understanding the viability of commercial extraction and refining, given gallium’s strategic importance in semiconductor and defence industries.

Alongside metallurgical efforts, a ground-based gravity survey is planned over the Masson copper-nickel prospect to refine structural understanding ahead of follow-up drilling. The company is also extending its UltrafineTM surface geochemical sampling across the Mons Project, targeting additional gallium prospects and other critical and base metals. These exploration activities reflect a methodical approach to unlocking the Mons Belt’s multi-commodity potential, which includes copper, nickel, gold, and rare earth elements.

Financial Position and Exploration Expenditure

As at 31 March 2026, Nimy Resources held $5.13 million in cash, providing a solid foundation for ongoing exploration and study work. The company spent $323,000 on exploration and evaluation during the quarter, covering geophysical surveys, contract labour, and technical services. Corporate payments included $256,000 to related parties for director fees and management services, consistent with prior quarters.

This cash position supports the planned drill program design for Block 3 extensions and continued development of US market participation opportunities. While no production or development activities occurred this quarter, the focus remains on advancing the Mons Project through exploration and feasibility assessments.

Regional Exploration and Future Catalysts

Beyond Block 3, regional soil geochemistry sampling has collected over 4,500 samples across multiple structural and historical targets within the Mons Project. Results are pending and expected to be reported in the June quarter, potentially unveiling new targets for gold, critical minerals, and base metals. The company’s exploration pipeline continues to evolve, leveraging its recent discovery of the Masson copper-nickel-cobalt-gold-PGE prospect and fertile komatiite sequences analogous to those in the Kambalda region.

Investors will be watching closely for the upcoming scoping study outcomes, metallurgical test results, and drill program updates, which will provide clearer insights into the economic potential of Mons gallium resources. Nimy’s strategic positioning through US collaboration and government engagement adds a geopolitical dimension to its critical minerals ambitions, situating the company at the intersection of resource development and supply chain security in a competitive global market. This progress builds on the momentum from the company’s recent high-grade gallium test material shipment and the significant gallium extensions identified earlier this year.
