Oaky Creek Samples Hit 39.3% Antimony and 1.09g/t Gold in Latest Assays
Red Mountain Mining has reported its highest-ever antimony grades from rock chip samples at the Oaky Creek prospect in NSW, confirming the site’s potential as a major antimony-gold camp. Pending assay results and ongoing exploration could further unlock value in this underexplored region.
- Record rock chip samples up to 39.3% antimony and 1.09g/t gold
- Mineralisation extends over 500m at Oaky Creek South and 700m at Oaky Creek North
- Significant 1.5km antimony soil anomaly indicates further exploration potential
- Pending assay results from recent soil sampling at Oaky Creek South and East Hills
- Plans underway for expanded soil sampling and drill target definition
Record High-Grade Antimony Discovery
Red Mountain Mining Ltd (ASX, RMX) has announced a breakthrough in its exploration efforts at the Oaky Creek prospect, part of its 100%-owned Armidale antimony-gold project in New South Wales. Recent rock chip sampling has yielded antimony grades as high as 39.3%, alongside notable gold values up to 1.09 grams per tonne. These results represent the highest antimony concentrations recorded to date at Oaky Creek, underscoring the prospect’s potential to host a significant orogenic antimony-gold mineral system.
Expanding Mineralised Zones and Soil Anomalies
The mineralisation footprint is becoming increasingly defined, with samples confirming mineralised rock over a strike length of 500 metres at Oaky Creek South and 700 metres at Oaky Creek North. Moreover, a substantial 1.5-kilometre-long antimony soil anomaly at Oaky Creek North suggests that the mineralised system could extend well beyond currently sampled areas. This anomaly, combined with the high-grade rock chip results, positions Oaky Creek as a compelling target for further exploration.
Pending Assays and Next Steps
Red Mountain has recently completed detailed hand auger soil sampling at Oaky Creek South, with results expected imminently. Additionally, initial soil sampling at the East Hills prospect, located in the southern part of the tenement, is pending assay results. These data will be critical in refining exploration targets and guiding subsequent programs. Subject to positive outcomes, the company plans to replicate the hand auger soil and rock chip sampling approach at Oaky Creek North to delineate drill-ready targets.
Strategic Positioning in a Premier Antimony Province
The Armidale project lies within the Southern New England Orogen, a region recognised as Australia’s premier antimony province. The tenement stretches along the Peel Fault, a major structural corridor known for hosting over 400 orogenic gold and base metal occurrences but remains underexplored. Red Mountain’s exploration is tapping into this underexplored potential, with the geology dominated by folded Carboniferous metasediments and ultramafic mélanges, which are conducive to antimony and gold mineralisation.
Broader Exploration and Funding Outlook
Following a recent oversubscribed placement, Red Mountain is well funded to continue aggressive exploration across its Australian and North American critical minerals portfolio. The company is also advancing exploration at other targets within EL9732, including the Horsley Station and Horsley North gold prospects, where land access has been secured. The combination of high-grade surface results and strategic funding places Red Mountain in a strong position to unlock value from its critical minerals assets.
Bottom Line?
With record grades and expanding anomalies, Red Mountain’s Oaky Creek project is poised for a pivotal exploration phase that could reshape its critical minerals outlook.
Questions in the middle?
- Will upcoming soil assay results confirm the extent and continuity of the high-grade antimony mineralisation?
- How soon will Red Mountain initiate drilling to test the depth and volume of the Oaky Creek mineralised system?
- What are the implications of these findings for the regional antimony supply and Red Mountain’s market positioning?
