Trigg Minerals confirms shallow high-grade antimony at Wild Cattle Creek

• TMG looks to grow Achilles resource with historic samples averaging 4.83% antimony
• Assays were not used in the latest mineral resource update at the project
• Company says samples highlight potential for early, low-cost extraction

Special Report: Trigg Minerals has flagged high-grade antimony assays from samples within an historical underground adit at Wild Cattle Creek deposit in its Achilles project in northern NSW.

Wild Cattle Creek is Australia’s highest grade primary antimony resource at 1.52Mt at 1.97% antimony, comprising 960,000t at 2.02% in the indicated category and 560,000t at 1.88% inferred.

The newly discovered historical sample locations and corresponding antimony grades averaging 4.83% appear to have been accurately plotted on a drive plan and were included in an earlier resource estimate and preliminary feasibility report for Dundee Mines.

However, the assays were not included in the company’s 2024 revised resource estimate, providing additional upside and strong potential for future resource growth.

Notable intersections include: 

• 5.32m at 6.7% Sb;
• 5.42m at 9.6% Sb;
• 3.64m at 7.3% Sb;
• 2m at 12.7% Sb;
• 5m at 3.5% Sb;
• 2m at 9.6% Sb; and
• 2m at 9.4% Sb.

Trigg Minerals (ASX:TMG) says the samples confirm the presence of shallow, high-grade mineralisation within the deposit, suggesting the potential for higher overall grades than those indicated by drilling alone. 

The results also reinforce the deposit’s geological continuity and potential for early-stage extraction.

Early, low-cost extraction potential

Plus, there are more significant intersections in the parallel lode named Roula which were not included in the resource estimate, including 2m at 11.57% Sb and 1.26% tungsten, and 2m at 14.45% Sb and 0.84% W, including 1m at 27.6% Sb

Adit mapping and sampling provide strong evidence for lode repetition along strike and subparallel, complementary lodes, indicating broader structural complexity and exploration upside.

Trigg plans to update the Wild Cattle Creek resource by incorporating unmodelled data to capture additional value from tungsten and gold alongside antimony.

“The high-grade results strongly validate the continuity and tenor of antimony mineralisation at Wild Cattle Creek,” managing director Andre Booyzen said. 

“These outcomes reinforce our confidence that substantial high-grade mineralisation remains accessible at shallow depths, supporting our broader development strategy, and may inform future mine design by highlighting the potential for early, low-cost extraction.”

The company notes that a review of Dundee’s historical adit mapping and channel sampling provides strong evidence for lode repetition along strike and subparallel, complementary lodes, indicating broader structural complexity and exploration upside at the project.
