    SSR Mining sells Çöpler mine stake: design failure and risk lessons for engineers

    SSR Mining sells Çöpler mine stake: design failure and risk lessons for engineers

    First reported on MINING.com

    30 Second Briefing

    SSR Mining has agreed to sell its 80% stake in the Çöpler gold mine in eastern Anatolia to Cengiz Holding for US$1.5 billion in cash, sending SSR shares up 5.3% in pre-market trading and valuing the company at about US$5 billion. The transaction covers the mine, licences and all associated assets and liabilities, following a 2024 heap leach failure and landslide that left at least nine miners missing and was later linked to a third-party design flaw. SSR has already spent nearly US$150 million on reclamation and remediation, and analysts say the sale removes a major operational and reputational risk overhang.

    Technical Brief

    • Failure mechanism attributed to a third‑party engineered heap leach design flaw, confirmed by independent technical review.
    • SSR Mining has already deployed nearly US$150 million on reclamation and remediation works post‑failure.
    • Independent review findings triggered SSR’s own internal engineering review of Çöpler’s design, operation and risk controls.
    • Ongoing reclamation likely includes regrading, buttressing and drainage reconfiguration to stabilise failed leach slopes.
    • Monitoring going forward will need dense geotechnical instrumentation and real‑time slope/heap surveillance to regain regulatory confidence.
    • For similar heap leach operations, the case reinforces the need for rigorous third‑party design verification and independent geotechnical audits.

    Our Take

    Cengiz Holding’s purchase of SSR Mining’s 80% stake at Çöpler follows its separate deal to acquire First Quantum’s Çayeli copper-zinc mine, signalling a deliberate build-out of a diversified metals portfolio in Türkiye that could give it significant regional leverage in permitting and contractor markets.

    With at least $150 million already spent on reclamation and remediation at Çöpler after the 2024 landslide, the transaction effectively transfers a complex long-tail closure and liability profile to a domestic operator, which our database suggests is relatively uncommon in recent gold-mine divestments tagged under Failure and Safety.

    SSR Mining’s market value of about $5 billion versus the $1.5 billion cash consideration for Çöpler implies a substantial balance-sheet reset, likely freeing capital for lower-risk jurisdictions such as Canada, while Cengiz assumes both the upside and regulatory scrutiny attached to restarting a high-profile Turkish gold asset.

    SKRI ‘phytocapture’ at Raygorodok: dust control performance insights for mine engineers

    China’s Zijin Mining is expanding RG Gold’s Raygorodok operation in Kazakhstan with a $500 million processing plant while deploying SKRI’s ‘phytocapture’ system, planting over 100,000 Scots pines across more than 20 hectares about 1.7 km downwind of the open pit. Supercomputer modelling using regional wind-rose data sets tree species and spacing to form multilayered vegetative barriers, not simple landscaping. SKRI reports particulate-matter reductions above 40%, with the forest belt expected to capture roughly one-third of dust emissions as mining advances towards the barrier.

    Barrick’s Reko Diq copper project delays: capex and schedule lens for mine planners

    Barrick Mining has warned of “significant increases” to the capital budget and schedule for the 50%-owned Reko Diq copper-gold project in Balochistan, where Phase 1 was previously costed at US$5.6–6.0 billion and Phase 2 at US$3.3–3.6 billion, with first production targeted by end-2028. Citing escalating security risks in Pakistan and the wider region, Barrick will slow field development and extend the technical and financing review to mid‑2027, while keeping the project under “active management” with reduced capital spend. The porphyry deposit, holding an estimated 15 million tonnes of copper reserves and modelled for a 37‑year mine life, remains central to Barrick’s Tier 1 copper strategy and its long-term community commitments in Balochistan.

    Orica tech for smaller North American mines: blast design gains for engineers

    Orica is targeting smaller North American mines and quarries with the same digital blasting toolkit used on large sites, including its BlastIQ cloud platform for blast design and performance tracking and on-bench digital loading systems. Area Business Manager Elliott Giles told IM that these operations, aggregated, form a major explosives volume market, and are now adopting electronic detonators and precise blast modelling to cut oversize and improve fragmentation. For geotechs and drill‑and‑blast engineers, the shift means more consistent burden control, tighter vibration management and better data for pit wall stability assessment even on “small” jobs.
