A program of systematic field work has allowed Red Mountain Mining (ASX: RMX) to define five high-priority orogenic antimony targets for drill testing at the Oaky Creek prospect within its Armidale antimony-gold project in New South Wales.
Final assays from 900 auger soil samples at Oaky Creek and Oaky Creek South generated the high-confidence drill targets with values of up to 1.16% antimony and 612 parts per million arsenic.
The new results strengthen and support prior results from a single line of eight auger samples taken over the historical workings during 2025.
These samples returned values of as high as 1.36% antimony and 351ppm arsenic.
Extensional Auger Sampling
On the Oaky Creek South main grid, infill and extensional auger sampling of a previously-reported coherent 30 metre-wide antimony-arsenic auger soil anomaly returned up to 356ppm antimony and 413ppm arsenic.
This anomaly now covers 300m in strike extent and remains open to the northeast.
Multiple arsenic anomalies remain open at the edges of Oaky Creek South between the historical workings and Oaky Creek South main grid.
The company expects further surface sampling to the east and west of the current coverage to define additional antimony anomalies and potential drill targets.
Auger soil results at Oaky Creek North highlighted strong antimony-arsenic anomalies around mapped quartz-carbonate stibnite veins, with best values of up to 3,011ppm antimony and 859ppm arsenic.
Significant Antimony Prospect
Red Mountain believes the soil and rock chip results from Oaky Creek indicate a significant orogenic antimony mineral system with a strike extent of 3 kilometres.
This is analogous to the Hillgrove project situated east of Red Mountain’s tenure and owned by Larvotto Resources (ASX: LRV).
Oaky Creek is the highest-priority prospect within the Armidale project, and one of several known orogenic gold and antimony mineral occurrences within the tenement.
Red Mountain has collected 1,300 samples during the infill auger soil sampling campaign over the past six months to tighten its existing 100m x 50m spaced soil grid and better constrain drill targets.
This detailed systematic work has allowed the company to define the new orogenic antimony target regions at Oaky Creek for drill testing during the next quarter.
