SSR Mining’s Çöpler mine $1.5B sale: failure, design and risk notes for engineers
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
SSR Mining will sell its 80% stake in Turkey’s Çöpler gold mine and associated eastern Anatolia licences, assets and liabilities to Cengiz Holding for $1.5 billion in cash, sending SSR shares up 15% in New York pre-market trading. Operations at Çöpler have been suspended since a 2024 heap leach failure and landslide that left at least nine miners missing, with an independent review blaming a third-party engineered design flaw. SSR is now concentrating its portfolio in the Americas, including the Cripple Creek & Victor mine, and is reviewing its 20% interest in the Hod Maden project.
Technical Brief
- Independent review attributed the Çöpler heap leach failure to a third‑party engineered design flaw.
- SSR Mining initiated its own subsequent asset review, implying further geotechnical, hydrological and design back‑analysis of the leach system.
- Ongoing suspension of operations effectively acts as a risk control, preventing further loading or solution circulation on the failed heap.
- Any restart under new ownership will require redesign of heap geometry, drainage and stability monitoring to address the identified design flaw.
- Incident adds to a small but critical set of global heap leach failures driving tighter scrutiny of third‑party geotechnical designs and sign‑off processes.
Our Take
Within our 1104 Mining stories, only a small subset combine M&A with tagged Failure/Safety incidents, so SSR Mining’s $1.5B exit from the Çöpler gold mine after a 2024 landslide stands out as a case where a major safety event appears to have directly reshaped portfolio strategy.
SSR Mining’s remaining 20% interest in the Hod Maden development project suggests the company is pivoting away from high-profile operational risk in Turkey towards a lower-capex, minority exposure model while it reassesses risk tolerance after the Çöpler suspension.
The contrast between the nine missing miners at Çöpler and the 200 fatalities at Congo’s Rubaya mine in the same dataset underlines how tailings and slope-failure risk is being scrutinised across very different regulatory environments, which is likely to tighten lender and insurer requirements for gold projects in both Turkey and central Africa.
