Summary:Star Minerals acquires a 219km² Merredin gold project in WA’s Yilgarn Craton, a low-cost exploration tenement close to the idle Edna May gold processing plant....

Star Minerals (ASX: SMS) has fully secured a large-scale Merredin gold project via granted exploration licence E70/6810 in Western Australia’s Wheatbelt region, expanding the firm’s growing WA gold asset portfolio at minimal upfront capital expenditure. Covering 219 square kilometres of underexplored tenure on the metamorphic margin of the Yilgarn Craton, this new gold acquisition unlocks a major folded magnetic trend stretching 14.5km strike length, interpreted as prospective for shear-hosted gold mineralisation associated with BIF and mafic volcanic units. Situated just 30km from the care-and-maintenance Edna May gold mill, the Merredin gold project enjoys complete road and rail logistics infrastructure, forming a strategic secondary growth asset alongside Star’s producing Tumblegum South gold mine near Meekatharra. Amid sustained high Australian gold prices, the low-cost tenement acquisition delivers clear exploration upside without heavy early-stage financial risk for the emerging gold producer.

Merredin Gold Project & Acquisition Core Specifications

Star Minerals obtained the flagship Merredin tenement through direct tenement pegging and official government grant, with a supplementary northern exploration licence application E70/6831 lodged to expand the project boundary further north. Historical exploration across the area is extremely limited, with thick transported regolith (up to 23m) masking basement lithologies and leaving the district’s gold potential largely untested by modern drill programs.

Geophysical datasets from the Geological Survey of Western Australia confirm the prominent fold closure structure within the tenement boundaries. Intersecting crustal shear zones and granite-greenstone contact boundaries create ideal fluid trapping architecture for hydrothermal gold deposition, matching the metallogenic model that hosts multiple historic gold deposits across the Merredin-Walgoolan district.

Geological Prospectivity of the Merredin Gold Tenement

The core value of Star Minerals’ new Merredin gold project lies in its underexplored favourable structural and lithological combination.

1. BIF & Mafic Host Lithologies: Banded iron formation and altered mafic volcanics are proven high-grade gold hosts across the broader Yilgarn Craton, with scattered historic rock chip samples returning anomalous gold values within the Merredin tenement bounds.

2. Multi-Scale Structural Controls: A major NW-trending crustal shear zone cuts the entire project area, offset by late NE cross faults that create structural traps for gold-bearing hydrothermal fluids along the 14.5km folded magnetic corridor.

3. Thick Regolith Blanket as Exploration Opportunity: Deep transported cover limited early surface sampling by previous explorers, meaning the full extent of subsurface mineralisation remains untapped for systematic RC and aircore drilling.

Nearby regional analogues including Walgoolan and Edna May validate the district’s gold endowment; Edna May previously produced hundreds of thousands of gold ounces from identical shear-controlled greenstone mineralisation, proving the Merredin belt’s capacity for economic gold accumulations.

Strategic Business Value of the Merredin Gold Acquisition

Securing the Merredin gold project aligns perfectly with Star Minerals’ dual corporate strategy: generate near-term cash flow from Tumblegum South’s 45,000oz gold resource, while building a pipeline of low-cost exploration assets to drive long-term resource growthstarminera....The no-premium tenement staking model minimises balance sheet outlay, preserving working capital for field exploration programs scheduled to launch in late 2026. Proximity to the idle Edna May mill delivers massive downstream cost advantages: any future gold resource defined at Merredin can utilise existing crushing, leaching and tailings facilities, eliminating the multi-million-dollar CAPEX required to build standalone processing infrastructure for new discoveries.

For investors, the Merredin acquisition diversifies Star’s gold footprint away from the Meekatharra district, adding exposure to an entirely separate Yilgarn metallogenic sub-belt and reducing geographic concentration risk. As Australian gold output plateaus and new greenfield discoveries become scarce, low-infrastructure-proximate tenements like Merredin represent highly sought-after growth assets for small-cap gold developers.

Conclusion

Star Minerals’ acquisition of the 219km² Merredin gold project marks a transformative expansion of the company’s Western Australian gold portfolio. This low-cost tenement unlocks a vast untested 14.5km magnetic mineralised corridor on the Yilgarn Craton, with immediate access to idle regional processing infrastructure at the Edna May gold plant. Balancing near-term production at Tumblegum South and long-term greenfield exploration upside at Merredin, the acquisition positions Star Minerals to scale its gold resource inventory efficiently amid sustained strong gold pricing. Industry participants will closely track the upcoming geochemical sampling and RC drill programs designed to validate the project’s high untapped gold potential across the Merredin Wheatbelt mineral district.
