Ore Resources has identified a significant 2km gold-in-soils anomaly at its Miriam Project in Western Australia, highlighting multiple high-priority targets ahead of a major drilling campaign.
- Broad 2km +20ppb gold-in-soils anomaly along Miriam Shear Zone
- Seven refined +50ppb gold anomalies identified within the trend
- High-order anomalies align with cross-cutting faults, marking key drill targets
- Phase 4 drilling program underway, targeting 30,000m across Coolgardie projects
- Strong balance sheet with A$10.7 million cash and zero debt supports exploration
Emerging Gold Potential at Miriam
Ore Resources Ltd (ASX – OR3) has announced promising new results from surface geochemical soil sampling at its 100%-owned Miriam Project, part of the Coolgardie Gold Projects portfolio in Western Australia's prolific Goldfields region. The recent sampling has delineated a broad 2-kilometre-long gold-in-soils anomaly exceeding 20 parts per billion (ppb) along the Miriam Shear Zone, a structurally significant corridor known for hosting gold mineralisation.
This anomaly encompasses several prospects including Forrest, Forrest South, Forrest North, and Burbanks Monarch, with seven refined anomalies surpassing 50ppb gold concentration. Notably, some of these high-order anomalies extend up to 850 metres and coincide with cross-cutting faults, which are often critical conduits for gold deposition. These structural intersections have elevated Forrest North and Burbanks Monarch as high-priority drill targets.
Integrated Exploration Approach
The company’s exploration strategy leverages advanced geochemical techniques, including the Ultrafine+™ soil sampling method developed by CSIRO, which analyses ultra-fine clay particles for gold and associated elements. This approach has proven effective in detecting subtle geochemical signatures beneath transported cover, enhancing the reliability of surface sampling in the region.
Complementing soil sampling, Ore Resources has completed close-spaced ground gravity surveys over key prospects including Forrest, Burbanks Monarch, and the emerging Goroke prospect. The integration of geochemical, gravity, and magnetic geophysical data is expected to refine geological models and prioritise targets for upcoming drilling.
Advancing to Drilling and Development
With heritage clearances secured, Ore Resources plans to commence first-pass aircore drilling at priority regional targets from late March 2026. This drilling forms part of an expansive Phase 4 program targeting approximately 30,000 metres of combined reverse circulation, aircore, and diamond drilling across the Coolgardie Gold Projects throughout the year.
Phase 4 drilling has already begun at the Forrest prospect, focusing on oxide and fresh rock extensions with an initial 3,000 to 5,000 metres of reverse circulation drilling. The company’s strong financial position, boasting A$10.7 million in cash and zero debt as of December 2025, underpins its capacity to advance these exploration activities without immediate capital constraints.
Strategic Positioning in the Goldfields
Ore Resources benefits from operating in an infrastructure-rich mining province near Kalgoorlie, with access to skilled labour, established mining services, and transport links to ports. The Miriam Project’s location within the Kangaroo Hills Timber Reserve offers a favourable environment for exploration with conditional access approvals in place.
As the company continues to build on historical data and integrate new geochemical and geophysical insights, the emerging gold trend along the Miriam Shear Zone could represent a significant addition to its portfolio. The identification of multiple high-grade soil anomalies aligned with structural features bodes well for the potential discovery of economic gold mineralisation.
Bottom Line?
Ore Resources’ unfolding exploration story at Miriam sets the stage for a pivotal drilling season that could reshape its growth trajectory.
Questions in the middle?
- Will upcoming aircore drilling confirm the extent and grade of the identified gold anomalies?
- How might the integration of gravity and magnetic data refine targeting and impact drilling success rates?
- What are the potential timelines and capital requirements for advancing discoveries toward resource definition?
