TG Metals Boosts Indicated Gold Resource by 120% at Van Uden Project
TG Metals Limited has unveiled a major Mineral Resource Estimate upgrade for its Van Uden Gold Project, with Indicated gold ounces surging 120% to 152,600 oz and total pit constrained resources reaching 270,800 oz at 1.06 g/t Au. This marks a significant step in advancing the project towards near-term production.
- Indicated Resource ounces increase by over 120% to 152,600 oz
- Total pit constrained resource stands at 7.9Mt grading 1.06 g/t Au for 270,800 oz
- Recent drilling confirms mineralisation continuity and expands resource footprint
- Laterite material modelled at lower cutoff for potential low-cost heap leach processing
- Resource remains open for further growth along strike and at depth
Major Upgrade in Resource Confidence and Size
TG Metals Limited (ASX:TG6) has substantially increased the Indicated category of its Van Uden Gold Project resource by 120%, lifting it from 68,340 oz to 152,600 oz. The total pit constrained Mineral Resource Estimate (MRE) now stands at 7.9 million tonnes grading 1.06 g/t gold, containing 270,800 oz. This upgrade is underpinned by a recent December 2025 drilling campaign that not only expanded the resource but also improved geological confidence by converting a significant portion of Inferred resources into the Indicated category.
CEO David Selfe highlighted the importance of this milestone, noting that the enhanced Indicated resource provides a much stronger platform for advancing mining studies and assessing near-term production potential. The resource remains open both at depth and along strike, with multiple targets identified for further drilling.
Laterite Mineralisation and Processing Potential
A notable feature of the updated MRE is the separate modelling of the surface Laterite material at a lower cutoff grade of 0.10 g/t Au, reflecting its amenability to low-cost mining and heap leach processing. This contrasts with the 0.30 g/t cutoff applied to Oxide, Transition, and Fresh material types. Metallurgical testwork underway aims to confirm the economic viability of heap leaching for the Laterite zone, which benefits from minimal waste mining and lower operating costs.
The total Laterite resource accounts for over 1 million tonnes at 0.52 g/t Au, containing approximately 17,700 oz of gold, with indications that further laterite mineralisation along strike remains untested. This strategic approach to resource classification and processing could enhance project economics by unlocking value from near-surface material.
Robust Drilling and QAQC Foundations
The resource update incorporates a comprehensive drilling database of 5,148 holes totaling nearly 117,000 metres, including both historical and TG Metals’ recent programs. The December 2025 quarter drilling, conducted with industry-standard RC and diamond rigs, focused on infill and extension drilling to improve resource confidence and continuity.
QAQC protocols appear rigorous, with monthly reports from SGS Kalgoorlie Laboratory confirming excellent assay precision and accuracy. Certified reference materials and duplicate sampling underpin the reliability of the data, supporting the JORC 2012 classification of Indicated and Inferred resources. This solid data foundation is critical as the company moves towards feasibility studies and potential development.
Geological Setting and Resource Modelling
Van Uden sits within the Southern Cross-Forrestania Greenstone Belt, a prolific geological province in Western Australia. The deposit is structurally controlled along the Van Uden Shear Zone, hosting multiple mineralisation styles including primary quartz vein-hosted gold and secondary oxide and laterite mineralisation.
Resource estimation utilized Ordinary Kriging methods with detailed geological wireframing and variography to capture the complex geometry and variable orientation of the lodes. The block model has been validated through multiple statistical and visual checks, confirming the robustness of the resource estimate.
Strategic Location and Next Steps
The Van Uden Project benefits from proximity to existing gold processing plants at Marvel Loch and Edna May, potentially offering processing synergies and infrastructure advantages. TG Metals holds an 80% interest in the project, with the remainder owned by Barto Gold Pty Ltd.
This resource upgrade follows a series of encouraging drilling results earlier this year that confirmed thick, high-grade zones extending beyond previous resource boundaries, reinforcing the project’s growth potential. These developments set the stage for upcoming feasibility work and metallurgical test results that will clarify the economic parameters of the project.
Given the resource remains open and multiple unclassified targets exist, TG Metals is well positioned to continue expanding the Van Uden resource base. The company’s ongoing drilling campaigns and metallurgical programs will be critical to defining a viable mining operation in the near term.
Investors may find it useful to consider this resource upgrade alongside the recent thick, high-grade gold zones uncovered by TG Metals, which underpin the resource growth and improved confidence at Van Uden.
Bottom Line?
TG Metals’ substantial upgrade in Indicated resources at Van Uden sharpens the project’s development prospects, but ongoing metallurgical validation and drilling will be pivotal for translating ounces into production.
Questions in the middle?
- How will ongoing metallurgical testwork on Laterite material impact the project’s processing strategy and economics?
- What are the timelines and capital requirements for advancing Van Uden to feasibility and production?
- To what extent can further drilling convert unclassified and Inferred resources into Indicated, enhancing project confidence?
