21 May 2025 | West Perth, WA – Rox Resources (ASX:RXL) has achieved a major milestone in its metallurgical test work, confirming gold recoveries of 91.6% to concentrate from samples at its flagship Youanmi Gold Project in WA’s Mid West.

Conducted as part of the Definitive Feasibility Study (DFS), bulk flotation tests also returned concentrate grades of 49.9g/t Au, with up to 62.6% additional gold recoverable from tailings via cyanide leach. Test work using the Albion Process™ is now underway to optimise overall recovery.

Key Results:

  • 91.6% gold and 98.3% sulphur recovery to concentrate

  • Tailings leach recovery: 35.8–62.6%, with low reagent use

  • Albion Process™ to improve recovery from semi-refractory ores

  • Final gold recoveries expected to exceed PFS assumptions

Managing Director Phillip Wilding commented:

“It’s exciting to see recoveries exceeding our Pre-Feasibility Study expectations. The Albion Process could deliver further upside while lowering processing costs, supporting a compelling case for development.”

The metallurgical program, which began in January, will feed directly into Rox’s DFS due in November 2025. The work covers the major ore lithologies that comprise over 95% of the planned plant feed and is key to optimising the process flowsheet.

Additional dewatering, approvals, and resource updates are progressing in parallel as Rox works toward a production decision.
