Nimy Resources (ASX:NIM) highly favourable mineralogy assessment paves way for first metallurgical tests

Nimy Resources Limited (ASX:NIM)

Nimy Resources (ASX: NIM) is pleased to announce strong results from an assessment of the mineralogy at its Block 3 gallium discovery in WA.

■ The study undertaken by CSIRO characterised high-grade fresh rock samples from Block 3 Prospect, confirming the presence of gallium mineralisation in a chloritised schist.
■ The results are important because they will play a key role in the first metallurgical tests, which are about to commence at Curtin University (research-related MoU).
■ Curtin University will undertake metallurgical test work covering ore characterisation, gallium recovery analysis, extraction methods, and flowsheet development.
■ Drilling has outlined high-grade gallium over an area measuring 250m by 150m at Block 3. The mineralisation remains open, and the host geology extends for several kilometres.
■ Drilling to commence in early-May at the Block 3 prospect, testing potentially high-grade and near-surface mineralisation along strike.
■ Drilling and metallurgy results will underpin a maiden JORC Resource in 2025.
■ Nimy is actively progressing discussions with strategic partners and end-users to support the ongoing development of the unique Block 3 gallium discovery.

Nimy Technical Director Christian Price said: “The mineralogy studies have returned extremely favourable results which augur well for the first round of metallurgical tests about to start. “Metallurgical tests will play a key role in calculating a maiden JORC 2012-compliant Resource for Block 3. “This work will all be done in parallel with the next round of drilling, which is set to start in early May. “We are pushing hard to expedite progress at Block 3 on several fronts at the same time, enabling us to capitalise on the huge worldwide demand for gallium stemming from China’s recent export controls on critical minerals”

CSIRO Mineral Indicator Studies - IM4NiS – Block 3 Gallium Prospect

CSIRO's preliminary characterisation completed to date on the Block 3 high-grade zone, indicates the gallium mineralisation is hosted within chloritised schists, with total Ga assay concentrations in fresh rock ranging from 100 to 300 ppm. Three samples from between 76-79m in NRRC121 were used for the testwork (refer Figure 1), initial results announced 18th April 2024 (ASX: NIM).

The mineralogy of the schists is relatively simple, comprising talc, chlorite, with minor amounts of quartz and amphibole. Preliminary compositional analyses indicate that chlorite is the primary host for gallium, early estimates suggest gallium within chlorite ranges from 400 to 800 ppm.

Curtin University Agreement – Gallium metallurgical test work and studies

Nimy’s metallurgical test work agreement with Curtin University builds on the gallium-related research memorandum of understanding (MoU) between the pair announced on 18 March 2025.

The program encompasses ore characterisation, preliminary gallium recovery analysis, technical studies on gallium extraction methods, and development of flowsheet options for viable gallium extraction.

The Curtin University agreement is supported by the Resources Technology and Critical Minerals Trailblazer, funded by the Department of Education. Curtin University is partnering with Nimy Resources to manage this initiative through its Industry Exchange program. The Curtin University Western Australian School of Mines will facilitate the test work and studies at its Kalgoorlie Campus.

This agreement confirms Nimy Resources’ commitment to advancing the Block 3 Gallium prospect and unlocking its economic potential through rigorous scientific and technical collaboration.

SRK Consultants’ technical geology specialists have been appointed to oversee the gallium resource definition process, acting as Competent Person to establish a gallium resource at Block 3 compliant with JORC standards.

Next Steps

Further work is underway to characterise the saprolite and saprock domains and the surrounding lithology. The aim is to improve the area's geological knowledge, determine the gallium mineralisation's geological controls, and assess the potential to increase the footprint mineralisation zone at Block 3.

About Nimy Resources

Nimy Resources is a Western Australian exploration company that has prioritised the development of its recently discovered Mons Belt, situated 370km north-east of Perth and 140km north-northwest of Southern Cross a Tier 1 jurisdiction in Western Australia.

The Mons Belt represents a district scale discovery, spanning ~80km x 30km over 17 tenements and covering ~3005km2 north of the Forrestania greenstone belt. The Mons Belt provides a new and exciting frontier in critical metal exploration in Western Australia, the company is currently working with the CSIRO to advance the lithology and mineralisation types within one of Australia's newest greenstone belt discoveries in the Yilgarn Craton, a region with significant untapped potential.

Nimy Resources believes the Mons Belt offers multi commodity potential with the initial discovery of Masson (Cu, Ni, Co, Au & PGE's) in addition to Block 3 east prospect with high-grade gallium (Ga) discovered in the northern tenements.

In addition to these discoveries, the southern tenements have significant fertile komatiite sequences like those found in the Kambalda region of WA.

The Mons Belt is a district scale discovery with a land holding consisting of 17 approved tenements covering an 80km north/south strike of mafic and ultramafic sequences.
