Red Mountain Mining Reports High-Grade Antimony-Gold Assays from Rock Chip Sampling at Armidale Prospects

Red Mountain Mining (ASX: RMX) has reported a series of high-grade assays from rock chip samples collected at three prospects within its Armidale antimony-gold project in the Southern New England Orogen region of New South Wales.

The company recorded results of as much as 36.3% antimony and 0.36 grams per tonne gold at Oaky Creek in the northern part of the tenement, where it had previously reported antimony-in-soil assays of up to 333 parts per billion and rock chip values of up to 39.3% antimony and 1.09g/t gold.

Global testing company Intertek analysed samples from Oaky Creek North and Oaky Creek South for gold, antimony, silver, arsenic, and tungsten at its Townsville laboratory.

Multiple Anomalous Returns

20 samples from the East Hills prospect and returned a best result of 9.9% antimony, with a further two samples indicating that antimony mineralisation at East Hills extends well beyond the small historical workings.

A sample of quartz-fuchsite vein material from the Horsley Station historical prospect returned an anomalous gold value of 0.25g/t with evidence of ultramafic lithologies, while a nearby sample of similar material contained anomalous antimony of 0.18%.

Ultramafic lithologies are the preferred host for gold mineralisation along the regional Peel Fault system and the exposure supports Red Mountain’s interpretation that magnetic highs at Horsley Station and Horsley North represent structurally-bound ultramafic bodies.

Red Mountain is planing follow-up work at East Hills following receipt and interpretation of the results of the soil sampling program, and also intends to conduct soil and rock chip sampling at the Horsley Station and Horsley North gold targets, where it has now secured land access.

Orogenic Antimony-Gold Systems

Evidence of antimony and gold mineralisation from multiple prospects across Armidale’s 400 square kilometres of acreage has highlighted the tenement’s strong potential to host multiple orogenic antimony-gold systems within the Peel Fault and its various splays.

The strong spatial correlation between antimony and gold supports Red Mountain’s exploration model for Oaky Creek, which it considers analogous to Australia’s largest antimony deposit at Larvotto Resources’ (ASX: LRV) Hillgrove project.

The Southern New England Orogen is Australia’s premier antimony province, with the mineralisation occurring in hydrothermal quartz veins, breccias and stockworks, often in concert with gold and tungsten.
