Neometals Ltd (NMT), an Australian company focused on enabling the sustainable production of critical and valuable materials alongside exploration at its Barrambie Gold Project, has announced encouraging exploration results from its 100%-owned Barrambie Gold Project in Western Australia. Recent rock-chip and grab samples from the historic Rinaldi workings have returned high-grade copper assays, indicating significant copper mineralisation in the area. Historical records show that the Rinaldi workings produced approximately 1,407 tonnes of ore at an average grade of 9.8% copper.
Key assay results include samples returning up to 24.4% Cu, alongside notable gold and silver credits, such as 22.5% Cu, 2.10g/t Au, and 51.3g/t Ag in sample 25BRK36. The copper mineralisation is hosted in a laminated quartz vein within the Barrambie Sill, with malachite, azurite, bornite, and chrysocolla observed as stringers and veinlets. These findings underscore the potential for high-grade copper mineralisation within the Barrambie Greenstone Belt.
Neometals is preparing to commence initial RC drilling at Rinaldi, having received the necessary Permit of Work approval. This drilling program aims to test the vicinity of the mapped copper-rich veins previously exploited in historical mining operations. The results from this program will be used to guide subsequent copper exploration strategies across the broader Barrambie Project. Further plans are being refined for follow-up work at priority gold targets including initial drilling programs at Kismet, Woodies and Silver Lining.
Additionally, the Inferred Mineral Resource Estimate and mine plan for the advanced Ironclad deposit are undergoing updates, with reporting anticipated during the March Quarter 2026. Associated geotechnical, metallurgical, hydrological, and environmental studies are also progressing to support the submission of mining approval documents for the development of the Ironclad deposit. Managing Director Chris Reed highlighted the exciting opportunity to investigate the potential for high-grade copper mineralisation at Rinaldi, compared to other copper occurrences within the Barrambie Greenstone Belt.
