Lifting the bar: TG Metals has boosted its gold resource at the Van Uden project in Western Australia.
- Updated pit-constrained MRE stands at 7.9Mt at 1.06g/t Au for 270,800oz
- Indicated ounces have increased more than 120% to 152,600oz after recent drilling
- TG to explore for more growth with unclassified targets open at depth and along strike
Special Report: TG Metals has increased the mineral resource estimate for its Van Uden gold project in WA’s Southern Cross-Forrestania belt, following recent drilling.
The updated pit-constrained resource totals 7.935Mt at 1.06g/t Au for 270,800oz, including 4.557Mt at 1.04g/t Au for 152,600oz in the Indicated category and 3.378Mt at 1.09g/t Au for 118,200oz Inferred.
The update incorporates drilling completed in the December 2025 quarter along with historical data compiled since TG Metals acquired the project in March 2025.
TG Metals (ASX:TG6) said this represents a more than 120% increase in Indicated ounces, rising from 68,340oz to 152,600oz in the April 2026 estimate.
The bump lifts total gold inventory from 227,140oz to 270,800oz.
CEO David Selfe said the recent drilling had grown the resource and improved confidence in the geological model, with gaps along the 2.5km strike now better defined.
“The new MRE is pit constrained and we are confident of delivering additional MRE growth by drilling of numerous already identified targets outside the resource model,” he said.
Resource growth
Van Uden comprises a continuous mineralised zone formed from six historic prospects – Dieman, Heems, Kirk, Piglet, Tasman and Zeeman – along the Van Uden Shear Zone.
The shear zone hosts other nearby deposits, with the current resource covering a 2.5km section of a broader 54km corridor.
The update also separates out the laterite component of the system.
TG Metals applied a lower 0.10g/t Au cut-off for laterite material in a separate pit shell, compared to 0.30g/t Au for the primary resource.
This reflects the near-surface nature of the laterite and potential for lower-cost mining and processing, including heap leaching.
Testwork is underway to assess the suitability of heap leach processing.
The laterite component totals 1.053Mt at 0.52g/t Au for 17,700oz, while oxide, transition and fresh material account for the remainder of the resource, including 85,400oz oxide, 62,400oz transition and 105,300oz fresh.
Areas of unclassified mineralisation outside the current resource represent potential near-term drill targets.
Gold prices have also trended higher through April, providing a supportive backdrop as the company advances the project.
Next steps
Increasing drill density could bring this material into future resource categories, as TG Metals continues to advance the project toward development.
The company is also assessing development pathways, including potential toll treatment of existing stockpiles.
Xenith Consulting completed the resource estimate using ordinary kriging, with classification under the JORC Code.
Indicated material is generally defined by drill spacing of 25m by 25m or better, with wider-spaced areas classified as Inferred.
Van Uden is located west of the Mt Holland lithium mine, south of the Marvel Loch gold plant and southeast of the Edna May gold plant, placing it within an established mining region with access to nearby infrastructure.
The updated resource provides a larger and higher-confidence inventory, while highlighting scope for further growth along strike and at depth.
