Exploration Risks and Rewards: Can Red Mountain Unlock Oaky Creek’s Potential?

Exploration Expansion at Oaky Creek

Red Mountain Mining Ltd (ASX – RMX) has commenced an expanded auger soil sampling program at its 100%-owned Oaky Creek Antimony-Gold prospect, part of the broader Armidale Antimony-Gold Project in New South Wales. This initiative aims to refine and extend the understanding of a significant orogenic antimony-gold system that stretches approximately 3 kilometres along surface strike.

The program builds on earlier results that revealed exceptionally high-grade samples, including assays of up to 39.3% antimony and 1.09 parts per million gold. These findings suggest the presence of a large-scale mineralised vein system analogous to Larvotto Resources’ Hillgrove deposit, Australia’s largest known antimony-gold resource.

Strategic Significance and Project Context

Oaky Creek sits within a 400 square kilometre landholding that is highly prospective for critical minerals, particularly antimony and gold. The project’s geology, dominated by tightly folded Carboniferous metasediments and structurally controlled quartz-carbonate-stibnite veins, aligns with the characteristics of world-class orogenic mineral systems. Historical workings dating back to the late 19th century underscore the area’s mineral potential, although past mining occurred under vastly different economic conditions with antimony prices dramatically lower than today.

Red Mountain’s current sampling program is designed to cover the full strike extent of known soil anomalies at both Oaky Creek North and South, with results expected by March 2026. The company anticipates that these data will define multiple high-priority drill targets, setting the stage for a drilling campaign in the first half of the year.

Funding and Broader Portfolio

Backing from high net worth and family office investors, some with ties to Larvotto Resources, has secured funding through late 2025, enabling Red Mountain to execute its comprehensive exploration strategy. Beyond Oaky Creek, the company holds additional antimony projects in the United States, including the Utah Antimony Project and the Yellow Pine and Silver Dollar projects in Idaho, positioning it well within the critical minerals supply chain landscape.

With global supply constraints and strategic interest from governments in securing critical metals like antimony, Red Mountain’s exploration activities come at a timely moment. The company’s focus on Tier-1 mining districts and its aggressive exploration approach could see it emerge as a significant player in the antimony-gold sector.

Looking Ahead

As Red Mountain advances its auger sampling and prepares for drilling, the market will be watching closely for assay results and the identification of drill-ready targets. The company’s ability to leverage its strong investor support and expand its project portfolio through potential acquisitions adds further intrigue to its growth prospects.
