The company is testing the approximately three km strike extent of conventional antimony soil anomalies at Oaky Creek North and Oaky Creek South.
Previous work on the soil anomalies returned assay results of up to 39.3% antimony and 1.09 parts per million (ppm) gold for Oaky Creek.
The company’s management says there is evidence of a potentially large-scale orogenic antimony-gold vein system, which is analogous to Australia’s largest known antimony deposit at Hillgrove, also in NSW.
Results from analytical studies of the auger sampling are scheduled to be received in March and will help define drill targets ahead of the next drilling phase.
Earlier this year, Red Mountain obtained multiple exceptional high-grade samples with values of over 25% antimony and 0.1 grams per tonne gold from five different areas.
Notably, that program also returned samples from a creek exposure near the historical workings at Oaky Creek North, along with a soil anomaly approximately 500m north-west of the Oaky Creek South workings and a soil anomaly near the southern end of the Oaky Creek North soil anomaly.
Red Mountain has identified Oaky Creek as a priority target, among numerous prospects at the Armidale antimony-gold project.
Along with those plans, further targets under consideration include the Horsley Station and Horsley North gold prospects, in addition to East Hills, where antimony-gold mineralisation has returned highly encouraging initial results.
With a range of critical mineral projects in North America, Red Mountain is gaining international exposure and successfully listed on the U.S. Market (OTCQB) in mid-November, with its shares up 36% on the first day of trading.
The company also attracted funding support from three high-net-worth/family office investors in late 2025 to back its aggressive exploration plans.
RMX has been at 2.6cps today, up +4%.
