Mulwarrie Drilling Yields 13.2m at 8.5g/t Au Outside Current 350koz Resource

Mining By Maxwell Dee 3 min read

Gorilla Gold has reported compelling high-grade drill results at its Mulwarrie Gold Project in Western Australia, setting the stage for an ambitious resource expansion drilling campaign starting November 2025.

  • High-grade drill intercepts outside current 350koz resource
  • Notable results include 13.2m at 8.5g/t and 5.0m at 2.5g/t gold
  • Mineralisation extends over 2.5km strike and 500m depth
  • Resource update expected in Q4 2025
  • New multi-rig drilling program planned to double resource base

Strong Step-Out Drilling Bolsters Mulwarrie Prospects

Gorilla Gold Mines Ltd has announced a fresh tranche of high-grade assay results from its Mulwarrie Gold Project, located in Western Australia's prolific Goldfields region. These latest drill intercepts, notably 13.2 metres grading 8.5 grams per tonne gold and 5.0 metres at 2.5 grams per tonne, lie beyond the boundaries of the company's recently updated Mineral Resource Estimate (MRE) of 350,000 ounces at 3.6 g/t Au.

The results reinforce the project's significant growth potential, with mineralisation now defined along a 2.5-kilometre strike length and to depths of 500 metres. Multiple stacked lodes remain open both along strike and at depth, suggesting substantial upside beyond the current resource footprint.

Strategic Growth Drilling Program on the Horizon

Building on this momentum, Gorilla Gold plans to commence a multi-rig drilling campaign at Mulwarrie in November 2025. The objective is clear, to at least double the existing resource base. This aggressive exploration push aligns with the company's broader strategy to unlock value from its portfolio of brownfields projects in the region.

CEO Charles Hughes highlighted the significance of the new results, noting that they will be incorporated into an updated MRE expected in the fourth quarter of 2025. Meanwhile, Gorilla continues to operate four drill rigs at its nearby Comet Vale Project, targeting a major resource upgrade later this year.

Favourable Geology and Infrastructure Support

The Mulwarrie Project benefits from granted mining leases and proximity to established processing infrastructure, including the Davyhurst Mill just 10 kilometres away. The geological setting features a major north-west trending fault system with gold mineralisation associated with quartz veining and sulphide alteration. Metallurgical testwork has demonstrated excellent gold recoveries of up to 96%, including significant gravity extraction potential.

Historical mining and exploration activities have laid a foundation, but Gorilla Gold’s recent consolidation of tenure and systematic drilling have markedly advanced the project's profile. The company’s approach combines detailed geological logging, rigorous sampling protocols, and modern assay techniques such as photon assay to ensure data quality and reliability.

Looking Ahead, Unlocking Mulwarrie’s Potential

With high-grade mineralisation confirmed over a substantial strike and depth extent, and with multiple lodes open for expansion, Mulwarrie stands as a key growth asset for Gorilla Gold. The upcoming drilling program and resource update will be critical milestones, potentially reshaping the project's scale and economic outlook.

As Gorilla Gold accelerates its exploration efforts across multiple projects, including Comet Vale and Vivien, investors and analysts will be watching closely for how these developments translate into tangible value creation.

Bottom Line?

Mulwarrie’s expanding high-grade footprint signals a pivotal growth phase for Gorilla Gold, with the next resource update poised to reshape market expectations.

Questions in the middle?

  • How will the updated Mineral Resource Estimate impact Gorilla Gold’s valuation?
  • What are the timelines and expected scale for the upcoming multi-rig drilling campaign?
  • Could metallurgical and engineering studies alter project economics or development plans?
