Tali Resources has outlined approximately 9,000m of aircore drilling across the Don Juan-Alakol trend and Central Australian Suture prospects, with drilling scheduled to start in October.
The initiative aims to evaluate seven high-priority targets within the 45km-long Don Juan-Alakol alkaline ultramafic intrusive system, alongside a further five prospects along the Central Australian Suture.

The upcoming drilling programme within the Don Juan–Alakol trend will cover approximately 5,500m and focus on previously untested anomalies.
Identified targets include Don Juan South-East, Don Juan East, Don Juan South, Don Juan West and several locations within Alakol.
These areas were selected based on gravity and magnetic survey data indicating features that may represent multiple intrusive bodies considered prospective for carbonatite-associated mineralisation.
The Don Juan and Alakol prospects are located within an ultramafic intrusive system known to host aillikite, a rock type commonly found near carbonatite deposits.
Previous studies have shown a spatial and temporal link between aillikite lamprophyre and carbonatites, minerals frequently associated with niobium, rare earths, titanium, phosphorus and, potentially, copper mineralisation.
Alongside the Don Juan-Alakol drilling, Tali Resources is planning an additional 3,500m of aircore drilling at five targets on the Central Australian Suture: Caspian North, Caspian North-East, Verde East, Verde West and Hutt West.
Historical exploration in the area, including work by Toro Energy in 2011, involved soil, rock chip and lag sampling over the Don Juan prospect.
Findings highlighted responses for nickel and chromium, as well as pathfinder elements such as copper, arsenic and antimony.
In rock-chip samples, up to 3.2% total rare earth elements were recorded, including neodymium, dysprosium, terbium, praseodymium and yttrium.
These results indicate the potential for higher-grade rare earth mineralisation within the intrusive complex.
Tali Resources managing director Rhys Bradley said: “Our review of the Don Juan-Alakol trend has reinforced the scale and prospectivity of this 45km-long alkaline intrusive system.
“Historical drilling intersected aillikite in seven of eight holes, a rock type commonly found proximal to carbonatites, both globally and within the West Arunta.”
