ACG Metals’ first copper concentrate at Gediktepe: ramp-up notes for mine planners

30 Second Briefing
ACG Metals has produced its first copper concentrate from the Gediktepe mine in Turkey, completing the site’s shift from a single-stream gold-silver-zinc operation towards copper-focused output. The company is targeting 40,000 tonnes of copper per year at steady state and expects to reach full production by the end of 2026, with the ramp-up centred on higher throughput, improved recoveries and consistent concentrate quality. Management links the move to copper to growing demand from AI, electrification and other technology-led applications.
Technical Brief
- First copper concentrate was produced on budget, indicating process plant and commissioning aligned with cost estimates.
- Gediktepe’s processing flowsheet has been reconfigured from a single precious-metal/zinc stream to a copper-focused circuit.
- Ramp-up strategy explicitly targets progressive increases in mill throughput rather than step changes in nameplate capacity.
- Management is prioritising metallurgical recovery improvements, implying ongoing optimisation of grind size, reagent schemes and residence times.
- Consistent concentrate quality is a stated objective, suggesting tighter control of Cu grade, deleterious elements and moisture.
Our Take
Our database shows multiple recent items on ACG Metals’ Gediktepe copper-gold mine, including a July 2026 note on improved gold recovery via proprietary heap leaching, suggesting the company is systematically upgrading both oxide and sulphide value streams at this Turkish asset.
With Coal India preparing a 10% IPO stake sale in Mahanadi Coalfields, and separate coverage of SECL’s new highwall mining machine in India’s coal sector, this article underscores how Turkey-focused ACG Metals is leaning into copper and precious metals while Indian state-linked operators in Odisha and elsewhere remain anchored in coal expansion.
