AUSTRAL RESOURCES TO UNLOCK ADDITIONAL COPPER VIA HEAP LEACH REMINE USING JEX TECHNOLOGIES

Highlights:

• Identification of a Heap Leach Remine opportunity at Mt Kelly to recover previously unrecovered copper inventory within existing heaps

• Mt Kelly Heap Leach Mineral Resource Estimate (MRE), which identified approximately 45kt of residual copper metal remaining within the Mt Kelly heap leach stockpiles as of October 2024

• Evaluation of patented JEX Hydro-Jex® technology, a proven in-heap leaching system with over 20 years of global operating history

• Technology enables access to internal heap inventory that is not recoverable through conventional surface leaching methods

• Hydro-Jex® has demonstrated material recovery uplift and accelerated leach kinetics across multiple international heap leach operations

• Opportunity to enhance copper recovery without heap remining or restacking, reducing disturbance and capital intensity

• Potential to improve recovery efficiency and extend value from existing heap leach assets at Mt Kelly

Austral Resources Australia Ltd ( ASX:AR1 ) (“ Austral ” or the “ Company ”) is pleased to announce that it has encountered new and unique, Patented Technology to Optimise and Enhance the recovery of copper in its leaching operations in Australia. Austral has studied and documented quantities of otherwise unrecoverable copper per Austral’s ASX announcement dated 28 October 2024 “Mt Kelly Heap Leach Mineral Resource”. The heap leach includes approximately 45kt of residual copper metal remaining within the Mt Kelly heap leach stockpiles (22.6Mt @ 0.20% Cu Inferred Mineral Resource Estimate containing 44.6kt Cu), providing potential for future recovery through heap leach re-mining and JEX Tech Aus Pty Ltd has a potential and uniquely efficient process to complete its recovery.

The World-Class Technology is provided by JEX Tech Aus Pty Ltd which is a subsidiary of an Industry Leading company out of Nevada in the United States of America, JEX Technologies Corporation (“JEX”). The technology is Patented and Trademarked under the name of Hydro-Jex®.

Hydro-Jex® has been employed around the world for over more than 20 years, starting in the United States. It has significantly enhanced the leaching of metals in heaps. Hydro-Jex® has significantly enhanced the leaching of copper and precious metals in heaps at various operations around the world by multiples, compared to conventional extraction methods.

The Hydro-Jex® Technology will permit the Mt Kelly Leaching Operations to access inventory internal to its heaps that otherwise could only be accessed by remining and restacking the material. Hydro-Jex® has been demonstrated to be able to elevate the total recovery of metals in heaps, as it is applied inside the heaps as opposed to only being applied from the surface. This method accesses metal that surface leaching cannot, due to physical changes that occur inside the heaps with the percolation of solutions over time and depth.

Austral is excited to implement this technology, which not only enhances the recovery of metal, but also accelerates it.

This announcement is authorised for market release by Austral’s chairman, David Newling.
