 High-grade RC assays and visible gold in Menzies DD drilling
Key Points

  • Visible gold intersected in multiple diamond drill holes
  • Drilling aims to support maiden Underground Ore Reserves declaration in late CY25
Full Summary

Brightstar Resources has received results from a ~6,400m reverse circulation (RC) and diamond drilling program targeting infill and extensional resource drilling at the Yunndaga deposit, part of the 0.6Moz @ 1.4g/t Au Menzies Gold Project. Significant RC intercepts include 8m @ 6.67g/t Au from 245m, 4m @ 6.73g/t Au from 46m, and 8m @ 3.11g/t Au from 0m. The drilling also intersected visible gold in multiple diamond drill holes, with assays pending. The program aimed to infill areas within optimised stope shapes and test for down-dip extensions to known mineralisation, in support of an upcoming Mineral Resource Estimate upgrade and declaration of maiden Underground Ore Reserves targeted for late CY25. The results confirm the presence of high-grade, nuggety mineralisation typical of the Menzies deposits, highlighting the potential for a substantial, high-grade underground mining operation at Yunndaga.

Outlook

Brightstar is currently drilling across its portfolio, including underground diamond drilling in Laverton, surface diamond drilling in Menzies, and surface RC drilling in Sandstone. The company is progressing towards a Definitive Feasibility Study on a wider development scenario at its Laverton and Menzies hubs in 1H CY25.
