Patented Proprietary Recovery Process Demonstrated
ACG Metals Limited has announced significant improvements in gold recovery at its Gediktepe Mine in Türkiye, achieving commercial recovery of approximately 85%, up from a previous 75%, through a patented proprietary process. This new approach has also led to a 45% reduction in cyanide consumption and reduced leach cycle times, contributing to lower operating costs and improved margins. The company expects these enhancements to continue through the oxide ore phase and plans to apply the process to sulphide and transitional ore, demonstrating its metallurgical optimization capabilities ahead of its sulphide ramp-up and copper production.

About this update from Acg Metals Limited Class A
1 July 2026 ACG METALS LIMITED ("ACG" or the "Company") Patented Proprietary Recovery Process Demonstrated at Gediktepe ACG is pleased to announce a sustained improvement in gold recovery at the Gediktepe Mine, Türkiye, achieved through introducing a new product to the metallurgical recovery process: A proprietary technical approach developed by the Company, for which patent protection has been secured in Türkiye and is progressing in 35 other countries. Highlights · Commercial gold recovery of c.85%, compared to c.75% previously · Cyanide consumption reduced by c.45% · Reduced leach cycle times · Lower operating costs and improved margins · Demonstrated under commercial operating conditions · Patent approved in Türkiye for the proprietary process, with international applications in progress Work undertaken between April 2025 and June 2026 has delivered sustained and repeatable improvements in heap leach performance under commercial operating conditions. Higher recoveries, lower reagent consumption and faster kinetics are contributing to stronger cash flow and improved operating performance for oxide ore. The patented process reflects a structured optimisation approach developed internally by the Company, with broader applicability. The Company expects these improvements to continue through the remaining oxide phase and intends to apply the approach to sulphide and transitional ore. As the Company advances towards sulphide processing and copper production, these results demonstrate its ability to deliver practical metallurgical optimisation ahead of its sulphide ramp-up. Artem Volynets, Chairman and Chief Executive Officer of ACG, said: "These proprietary improvements in heap leach performance demonstrate the strength of our world-class technical team. As we move into the sulphide ramp-up phase and copper production, disciplined process control and recovery efficiency will be key to delivering performance and optimising cash flow." - ENDS - Inside information The information contained within this announcement is considered by the Company to constitute inside information as stipulated under the Market Abuse Regulation (EU) No.596/2014 (as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018).
