ACG Raises Gold Recovery at Turkey’s Gediktepe Mine to 85% With Patented Heap Leach Process While Cutting Cyanide Use by 45%

ACG has raised gold recovery at Turkey's Gediktepe Mine from 75% to 85% using a patented proprietary heap leach process that also cuts cyanide consumption by 45%, delivering improved margins on oxide ore ahead of the mine's transition to sulphide processing and copper production.

ACG has achieved a sustained improvement in gold recovery at its Gediktepe Mine in Turkey, raising commercial recovery from approximately 75% to 85% through a proprietary technical approach developed internally by the company, for which patent protection has been secured in Turkey and is progressing in 35 other countries.

The improvement, delivered under commercial operating conditions between April 2025 and June 2026, is accompanied by a 45% reduction in cyanide consumption, reduced leach cycle times and lower overall operating costs — a combination that is contributing to stronger cash flow and improved margins on oxide ore processing.

ACG Chairman and CEO Artem Volynets described the results as demonstrating the strength of the company’s 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,” he said.

The company expects the improvements to continue through the remaining oxide phase and intends to apply the patented process approach to sulphide and transitional ore as Gediktepe advances toward copper production. The broader applicability of the proprietary process beyond Gediktepe is also highlighted as a potential asset for the company.
