22 May 2025 | South Perth, WA – Astral Resources (ASX:AAR) has delivered outstanding metallurgical results from its Feysville Gold Project, with gold recoveries of up to 98.1% confirmed from initial testwork at the Kamperman and Rogan Josh deposits. The results support the inclusion of these satellite deposits in the upcoming Mandilla Pre-Feasibility Study (PFS).

Five composite samples from Kamperman and two from Rogan Josh underwent gravity and cyanide leach testing. Three Kamperman samples returned an average recovery of 98.1%, confirming free-milling characteristics. The remaining two, which contained elevated copper, recorded 87.9% but are expected to improve with higher cyanide concentrations in follow-up tests.

Key Results:

  • Kamperman: 3 samples averaged 98.1% recovery; 2 samples averaged 87.9% (high copper impact)

  • Rogan Josh: 2 samples averaged 91.5% recovery at an average head grade of 0.70g/t Au

  • Low reagent consumption and rapid leach kinetics across both deposits

Managing Director Marc Ducler stated:

“These results clearly demonstrate that the simple, low-cost processing route proposed for Mandilla will also suit ore from Kamperman and Rogan Josh. This is a key step toward incorporating Feysville into the broader Mandilla mine plan.”

The combined Feysville resources now total 5Mt @ 1.2g/t Au for 196koz, strengthening Astral’s consolidated Mineral Resource base of 1.76Moz.

Additional assay results from RC and aircore drilling at Feysville are due later this quarter, alongside ongoing in-fill and extensional drilling at the nearby Iris and Hestia deposits.
