Striking Gold: Red Mountain Mining Reports Highest Antimony Grades to Date at NSW Project
Red Mountain Mining (ASX: RMX) has announced exceptional antimony and gold grades from recent exploration at its Armidale project, delivering the most promising results to date with antimony values reaching a remarkable 39.3% in rock chip samples. These findings significantly enhance the project's potential as a major orogenic antimony-gold camp in New South Wales.
Record-Breaking Antimony Results Confirm Major Discovery Potential
Recent rock chip sampling at the Oaky Creek South prospect has yielded the highest antimony grades yet for the Red Mountain Mining Armidale project, with standout results including:
- 39.3% Sb and 0.16g/t Au
- 33.5% Sb and 1.09g/t Au
- 19.4% Sb and 0.52g/t Au
These impressive results were collected during follow-up auger soil sampling at the Oaky Creek South prospect within Red Mountain's 100% owned Armidale antimony-gold project (EL9732) in the Southern New England Orogen of northeast New South Wales.
The findings confirm significant mineralisation across a 500-meter strike extent at Oaky Creek South and a 700-meter strike extent at Oaky Creek North, with additional untested extensions indicated by a ~1.5km long antimony soil anomaly.
"These exceptional grades confirm Oaky Creek's potential to host a major orogenic antimony-gold camp," said Red Mountain Mining. "The latest rock chip sample of 1.09g/t Au is also the first result over 1g/t gold recorded for the prospect."
Strategic Exploration Program Advancing Rapidly
Red Mountain is executing a methodical exploration strategy across its Armidale project:
- Approximately 250 hand auger soil samples were collected at 10m and 20m spacing across Oaky Creek South
- Results from this sampling program are expected before the end of October
- Initial 50m x 100m spaced soil sampling has been completed at the East Hills antimony prospect in the southern portion of EL9732
- Further sampling is planned for the Oaky Creek North soil anomaly to define prospective drill targets
- The company has secured land access to the Horsley Station and Horsley North gold targets for planned soil and rock chip sampling
The company is well-funded to continue aggressive exploration following a recent oversubscribed placement, with analytical results for all ongoing sampling programs expected before the end of October.
Understanding Antimony: A Critical Metal with Growing Importance
Antimony is classified as a critical metal due to its importance in various industrial applications combined with supply constraints. Its primary uses include:
Industrial Applications of Antimony
Antimony serves numerous crucial industrial functions that make it a strategically important element:
-
Fire Retardants: Antimony trioxide is widely used in flame-retardant formulations for fabrics, toys, plastics, and aircraft materials. It functions as a synergist with halogenated compounds to improve fire resistance.
-
Battery Technology: Antimony is used in lead-acid batteries to improve charging characteristics and mechanical strength. It's also being explored for next-generation battery technologies.
-
Semiconductor Manufacturing: High-purity antimony compounds are used in the production of semiconductor materials, particularly for infrared detectors and diodes.
-
Military Applications: Antimony is used in ammunition, infrared detectors, and night-vision devices, which contributes to its classification as a strategic metal.
Geological Context
The Southern New England Orogen is recognised as Australia's premier antimony province. Red Mountain's Armidale project lies approximately 85km west of Australia's largest known antimony deposit, Larvotto's Hillgrove deposit, and extends for 85km along the western side of the Peel Fault.
The geology is dominated by isoclinally folded Carboniferous metasediments of the Tamworth Belt, which is a forearc basinal package related to west-dipping subduction of oceanic crust beneath the Lachlan Orogen.
Project Timeline and Next Steps
Red Mountain has outlined a clear roadmap for advancing the Armidale project:
| Timeline | Activity |
|---|---|
| October 2025 | Receive analytical results from hand auger soil sampling at Oaky Creek South |
| October 2025 | Receive results from initial soil sampling at East Hills antimony prospect |
| Q4 2025 | Undertake similar program of hand auger soil and rock chip sampling at Oaky Creek North |
| Q4 2025 | Soil and rock chip sampling at Horsley Station and Horsley North gold targets |
| Ongoing | Work to secure land access to ground-truth stibnite and jarosite spectral anomalies across EL9732 |
Investment Potential: Positioned for Growth in Critical Metals
Red Mountain Mining presents a compelling investment case based on several key factors:
-
Strategic Asset Portfolio: The company holds a diversified portfolio of critical minerals including antimony, gold, lithium and base metals across Australia, Canada, and the USA.
-
Premier Antimony Location: The Armidale project is located in Australia's recognised premier antimony province along the Peel Fault System, which has world-class mineral potential with over 400 known orogenic gold and base metal occurrences.
-
Exceptional Early Results: The high-grade antimony results (up to 39.3%) are indicative of substantial mineralisation potential.
-
Strong Financial Position: Following a recent oversubscribed placement, the company is well-funded to continue aggressive exploration.
-
Experienced Team: The company has demonstrated geological expertise in identifying and developing critical mineral assets.
Why Investors Should Follow Red Mountain Mining
Red Mountain Mining represents an opportunity to gain exposure to the critical minerals sector through a company with high-grade antimony and gold assets in a premier geological setting. The exceptional grades reported from Oaky Creek, combined with the company's strategic positioning along the highly prospective but underexplored Peel Fault System, create significant potential for value creation.
The company's well-funded position allows for continued aggressive exploration across its portfolio, while the pending assay results expected in October 2025 provide near-term catalysts for potential share price appreciation. With growing global demand for antimony across various industrial applications and limited supply sources, Red Mountain's advancing exploration program at the Red Mountain Mining Armidale project could position it as a significant player in this critical minerals space.
Investors seeking exposure to critical minerals with near-term exploration catalysts should keep a close watch on Red Mountain Mining as it progresses its promising Armidale antimony-gold project.
