Brightstar Resources Limited Advances Sandstone Gold Project towards Mid-Tier Production

Strategic Insights

— 1 min read

Brightstar Resources Limited has been expediting exploration and study efforts at its Sandstone Gold Project since acquiring Alto Metals Limited and the Montague East Gold Project in late 2024. The company is advancing a Pre-Feasibility Study (PFS) targeting delivery in 1H CY26, with preliminary assessments suggesting a 2.5-3.5Mtpa processing plant located in Sandstone will likely optimize operational and financial outputs. The project is expected to unlock significant value, with a current Mineral Resource Estimate (MRE) of 33Mt @ 1.5g/t Au for 1.5Moz targeted for an upgrade in 2H CY25.

Key Takeaways:

  • Brightstar Resources Limited has expedited exploration and study efforts at its Sandstone Gold Project since acquiring Alto Metals Limited and the Montague East Gold Project in late 2024.
  • The company is advancing a Pre-Feasibility Study (PFS) targeting delivery in 1H CY26, with preliminary assessments suggesting a 2.5-3.5Mtpa processing plant located in Sandstone will likely optimize operational and financial outputs.
  • The project is expected to upgrade the current Mineral Resource Estimate (MRE) of 33Mt @ 1.5g/t Au for 1.5Moz in 2H CY25, incorporating results from the 2025 drilling program to support the declaration of maiden Ore Reserves in the PFS during CY26.
  • The company aims to achieve first gold production in 2H CY28, aligning with continued planned production growth from Brightstar's Laverton and Menzies hubs to target a Group production profile of +200koz p.a. by 2029.
  • Brightstar's exploration and project development teams have made significant progress on the Sandstone Gold Project since acquisition, completing a +80,000m drilling campaign, and advancing metallurgical and geotechnical assessments to confirm gold recovery rates and open pit stability.
  • The company is aggressively pursuing organic growth through systematic exploration programs in CY25 to unlock Sandstone's full potential.

Statistics:

  • Current Mineral Resource Estimate (MRE): 33Mt @ 1.5g/t Au for 1.5Moz
  • Targeted upgrade of MRE in 2H CY25:

* Incorporating results from the 2025 drilling program

* Supporting declaration of maiden Ore Reserves in the PFS during CY26

  • Planned gold production:

* First gold production in 2H CY28

* Group production profile of +200koz p.a. by 2029

  • Process plant capacity: 2.5-3.5Mtpa
  • Haulage costs for Montague ore: approximately gold equivalent
