Red Mountain Mining Limited has revealed exceptional high-grade antimony results from its Armidale Antimony-Gold Project, with assays reaching up to 28.34% antimony. The encouraging findings support prospects for a large orogenic system, with further gold assay results and exploration work ahead.
Red Mountain Mining Limited announced encouraging results from its Armidale Antimony-Gold project in the Southern New England Orogen of New South Wales. The company’s recent program at the Oaky Creek prospect has returned high-grade antimony values from rock chip samples, including two standout results of 28.34% and 28.33% antimony. These findings, obtained from quartz-stibnite veining, suggest that the historical workings may only represent a fraction of a potentially extensive orogenic antimony system. Additional samples, extending up to 500 meters from former mining areas, have also shown promising grades with ten chips exceeding 2.5% antimony.
The exploration work has been complemented by soil surveys that indicate significant antimony anomalies. Although outcrop exposure is limited in some areas, the spatial correlation between high-grade rock chip samples and elevated soil readings reinforces the potential for a large tonnage deposit. Further plans include shallow costeaning to expose bedrock beneath strong soil anomalies, detailed geological mapping along the costeans, and a systematic soil and rock chip sampling campaign targeting both the East Hills antimony and Horsley Station gold prospects. Gold assay results for the Oaky Creek samples are pending and anticipated in July, and these could provide additional insights given the historical association of high-grade antimony systems with gold mineralisation.
Red Mountain Mining’s work is technically grounded, with assays carried out using sodium peroxide fusion and ICP-MS, ensuring reliable and comparable results across samples. The project lies on historically mineralized terrain along the Peel Fault system, an area known for its world-class mineral potential and significant geological complexity. The firm’s methodical approach, including planned extensive soil sampling grids and costeaning surveys, is designed to refine the drill-testable targets expected to emerge later in 2025.
From a sentiment perspective, investors may view the news as bullish given the exceptionally high antimony grades and the potential for coexisting high-grade gold mineralisation, underscoring the possibility of discovering a major deposit in a proven mining district. On the other hand, there remains a bearish note tied to the early-stage exploration nature of the project—pending gold assay results and inherent exploration risks could temper short-term enthusiasm among caution‐oriented market participants.
