The current program was drilled on 100m by 400m-spaced lines, with holes about 25m apart and averaging 40m deep. Results for another 4,500m of drilling, mostly from the northern end of the prospect, are still in the lab and due later this month.
Great Southern says it plans to follow up the current aircore drill program with a targeted reverse-circulation (RC) drilling campaign in early 2026 to chase the higher-grade zones now emerging.
Great Southern Mining managing director Matthew Keane said: “Given the extensive strike length of the Amy Clarke surface gold anomaly and the prospect’s location on known gold bearing structures, Great Southern sees significant gold potential at Amy Clarke.”
Importantly, since the newly discovered shallow gold hits are hosted in semi-fresh rock it gives Great Southern a firsthand look at the host geology and the key structures driving the mineralisation.
The company says the mineralisation appears to sit in several related settings, including quartz veins within shear zones and along the contact line between the volcanic and sedimentary rocks, where old intrusions have reacted with mineral-rich fluids.
In short, the findings point to a classic multi-phase gold system typical of the Duketon Greenstone Belt, where flowing fluids along big shear zones tend to concentrate the gold.
Adding to Amy Clarke’s appeal, the prospect sits just eight kilometres north of Regis Resources’ Garden Well mill and only 3.5 kilometres south of Regis’ Erlistoun open pit - a mine that has already churned out more than 320,000 ounces of gold and is hosted in strikingly similar geology.
Elsewhere, Great Southern is also hard at work on a 7,000m RC drilling blitz at its nearby Golden Boulder prospect.
The historic Golden Boulder ground is littered with more than 50 old workings across 3.7 kilometres of strike and once produced gold at an eye-popping average of 29g/t.
Sitting on the same north–south structure as Regis’ Rosemont, Ben Hur and Baneygo deposits, Golden Boulder is shaping up as a serious follow-up prize.
Although Duketon maybe stealing the headlines right now, Great Southern has also placed a big bet on a copper-gold discovery in Queensland.
Together with its heavyweight partner, South African gold giant Gold Fields, the pair have rolled the dice with a high-impact diamond drilling campaign at Edinburgh Park in Far North Queensland.
The global major is chasing two standout IP targets, dubbed Leichhardt Creek and Mt Dillon, which both show all the hallmarks of large, intrusion-related gold-copper-silver systems.
With shallow gold already lighting up the maps at Amy Clarke, momentum building at Golden Boulder and deep copper-gold targets now on the radar in Queensland, Great Southern Mining has plenty of irons in the fire.
As the next batch of assays come in and the rods keep spinning well into 2026, Great Southern looks set to deliver lots of news flow. With the whiff of a new discovery in the air from both sides of the country, the company looks set write its next big chapter.
