Red Mountain Mining (ASX: RMX) has confirmed the presence of multiple drill-ready antimony targets at the Oaky Creek prospect within its Armidale project in New South Wales, following the second batch of analytical results from an auger soil sampling program.
Newly discovered stibnite vein rock samples collected 600 metres from the Oaky Creek South workings returned grades of up to 28.1% antimony, highlighting the potential for a new extension to the current mineralised system at Oaky Creek.
Conventional and auger soil sampling and rock analytical results of up to 39.3% antimony and 1.09 parts per million gold also indicated the potential of a large-scale orogenic antimony-gold vein system with a strike extent of 3 kilometres at surface.
The company believes this system is analogous to Australia’s largest-known antimony deposit at Hillgrove, situated 100km from the Armidale project and owned by Larvotto Resources (ASX: LRV).
Oaky Creek North Sampling
Soil sampling from the southern end of Oaky Creek North has further supported the north-northwest-trending antimony anomaly, returning values of up to 137ppm antimony and 334ppm arsenic.
The results align with previously-identified conventional soil anomaly and mineralised stibnite-bearing rock sampling, providing further evidence for widespread antimony mineralisation at Oaky Creek.
Results for a further 900 auger soil samples collected during January and February are expected this month.
These will be combined with existing datasets to refine multiple orogenic antimony vein targets ahead of planned drill testing.
Further assays are also pending for the company’s Thompson Falls project in the US following recently announced initial high-grade antimony results.
Premier Antimony Province
Red Mountain’s wholly owned Armidale project covers more than 391 square kilometres of the Southern New England Orogen in northeastern NSW.
The region has been recognised as Australia’s premier antimony province, where the mineralisation occurs in hydrothermal quartz veins, breccias, and stockworks, often with associated gold and/or tungsten mineralisation.
Armidale has an extensive 85km length along the western side of the Peel fault system, which has world-class mineral potential with over 400 known orogenic gold and base metal occurrences along 400km of strike.
The system has been historically underexplored, with less than 200 mostly-shallow drill holes focused on discrete prospects.
Oaky Creek is Red Mountain’s priority focus and is one of several known orogenic gold and antimony mineral occurrences within the tenement.
