Neometals has upgraded the Ironclad gold deposit resource at its Barrambie Project to 15,000 ounces, with a significant portion now classified as Indicated, underpinning plans for near-term development.
- Updated Mineral Resource Estimate totals 15,000 ounces gold
- 86% of ounces classified as higher-confidence Indicated category
- Higher-grade domain contains 12,000 ounces at 2.1g/t gold
- Resource supports upcoming scoping study and mine planning
- Ongoing drilling and approvals progressing for potential open pit mining
Resource Upgrade Signals Progress at Ironclad
Neometals Ltd (ASX:NMT) has announced an updated Mineral Resource Estimate (MRE) for its Ironclad gold deposit, part of the 100% owned Barrambie Gold Project in Western Australia. The revised estimate reports approximately 285,000 tonnes at 1.6 grams per tonne (g/t) gold, equating to 15,000 ounces, marking a 15% increase in total ounces compared to the previous June 2025 estimate.
Crucially, 86% of these ounces are now classified in the Indicated category, reflecting a higher level of confidence in the resource. This upgrade is underpinned by extensive infill drilling completed throughout 2025, combined with historic data, which has refined the geological model and improved the understanding of higher-grade mineralisation zones.
Focus on Higher-Grade Domains
The updated MRE highlights a substantial higher-grade domain within the deposit, estimated at 180,000 tonnes grading 2.1 g/t gold for 12,000 ounces. This zone extends from surface and is structurally controlled within gabbro-hosted shear zones, which are the primary hosts to the mineralisation. The delineation of these higher-grade areas supports Neometals’ strategy to prioritise Ironclad for near-term production.
The resource is reported above a 0.5 g/t cutoff grade within an optimised pit shell based on a gold price of A$6,500 per ounce. The deposit extends approximately 380 metres along strike and plunges northwards to depths of up to 140 metres, making it amenable to open pit mining methods.
Technical and Regulatory Progress
Neometals has submitted a Native Vegetation Clearing Permit application to the Department of Water and Environmental Regulation, a key step towards securing mining approvals. Concurrently, the company has completed flow-sheet design for a second phase of metallurgical test work, with sampling underway to validate processing parameters.
Looking ahead, the updated MRE will form the foundation for a scoping-level study targeted for completion in March 2026. This study will assess the economic viability of mining Ironclad and guide further technical evaluations including geotechnical, hydrological, and metallurgical studies. Additionally, resource extension drilling is planned to test potential down-plunge extensions of mineralisation, while exploration at other prospects within the Barrambie tenure continues.
Strategic Implications for Barrambie
The Barrambie Gold Project, located within the prolific Murchison Gold Belt, has seen limited modern exploration until Neometals’ recent efforts. The updated Ironclad resource represents a significant milestone in advancing the project towards production readiness. With a high proportion of ounces in the Indicated category and well-defined higher-grade zones, Neometals is positioning Ironclad as a cornerstone asset within its portfolio.
While the company also holds the world’s second highest-grade hard-rock titanium deposit at Barrambie, the focus on gold exploration and development is gaining momentum. The updated resource and forthcoming scoping study results will be closely watched by investors and industry observers as indicators of the project’s potential to contribute to Neometals’ growth trajectory.
Bottom Line?
Neometals’ Ironclad resource upgrade sets the stage for a pivotal scoping study and potential mining development.
Questions in the middle?
- How will the upcoming scoping study impact the timeline for Ironclad’s development?
- What are the key risks in converting the Indicated Mineral Resource to Ore Reserves?
- How might metallurgical test results influence processing strategies and costs?
