Auravelle Metals Limited has completed preliminary metallurgical testwork on the Sheoak prospect within the Nuckulla Hill Gold Project in South Australia, returning an average gold recovery of 90.5% from bulk leach extractable gold bottle roll analyses.

The initial testwork used 22 reverse circulation samples representing transitional and fresh material from central Sheoak. Individual recoveries ranged from 81% to 97%, indicating that the gold mineralisation is non-refractory and well-suited to conventional carbon-in-leach processing methods.

Prior reverse circulation drilling at Sheoak defined a gold trend extending over at least 600 metres, remaining open to the north, south and at depth. The company raised $1.5 million in July 2026 to fund ongoing exploration activities across its tenure.

“The results from this preliminary testwork are very pleasing with excellent recoveries from the samples taken. The initial work gives a positive indication for potential gold recoveries at Sheoak. The non-refractory nature of the gold mineralisation is also highly encouraging and gives the Auravelle team confidence to drill out and expand Sheoak, as well as continue our search for additional such deposits within the Nuckulla Hill project.” — Andrew Muir, Managing Director

Detailed metallurgical work will follow once further infill and extensional drilling delineates the full scale of the mineralised system. Field operations are set to resume shortly, with discovery-focused aircore drill testing of Nuckulla Hill soil and structural targets scheduled to commence in early September 2026.

“We look forward to the next steps in exploring the project, with discovery focussed aircore drilling to commence within coming weeks testing multiple of regional targets and then followed by infill and extensional RC drilling at Sheoak, Sheoak East and Bimba.” — Andrew Muir, Managing Director

Reverse circulation drilling for infill and extension at Sheoak is scheduled to follow in mid-late September 2026.
