    Codelco’s El Teniente setback: seismic risk and supply impacts for mine planners

    Codelco’s El Teniente setback: seismic risk and supply impacts for mine planners

    First reported on MINING.com

    30 Second Briefing

    Suspended development of the Andes Norte section at Codelco’s El Teniente, triggered by new studies of an “emerging seismic phenomenon” at greater depth, may last up to two years and follows a July 2025 rockburst equivalent to magnitude 4.2 that killed six workers in adjacent Andesita and Teniente 7 panels. El Teniente’s output is already about 27% lower year-on-year and Codelco has conceded its 1.7 Mt/y copper target for 2030 is unattainable, tightening a market where CRU reports one LME participant holding 50–79.99% of live copper warrants. Comex September copper hit an intraday record of $6.7045/lb as Chile posted its weakest Q2 copper production in nearly 20 years, with traders diverting metal into the US ahead of possible tariffs.

    Technical Brief

    • Six-month geotechnical review at Andes Norte identified a new deep-level seismic mechanism unlike historically managed hazards.
    • The July 31, 2025 rockburst in Andesita and Teniente 7, magnitude-4.2 equivalent, triggered criminal, regulatory and technical investigations.
    • Suspension of Andes Norte development for up to two years is explicitly framed as a worker-safety protection measure, not an economic optimisation.
    • The emerging seismic phenomenon is described as depth-related, implying possible transition from structurally controlled to stress-driven failure regimes.
    • Similar deepening projects globally are being cautioned that conventional rockburst controls may be insufficient once operations push into comparable stress domains.

    Our Take

    In our database, Codelco already features heavily in recent copper price coverage, and the El Teniente setback compounds a pattern where Chilean supply issues are repeatedly cited alongside tight LME warrant control and record Comex levels above $6.60/lb.

    The suspension at the Andes Norte section lands just as Codelco is also delaying its Maricunga lithium project to 2034, signalling that Chile’s state miner is simultaneously under strain in both copper and lithium build‑outs rather than being able to lean on battery metals growth.

    With El Teniente output already at a 25‑year low and Codelco publicly shifting to ‘profitability over volume’ in July 2026, high‑cost or geotechnically complex copper expansions in the Andes are likely to face tougher internal hurdle rates, which could open space for lower‑risk producers such as Freeport‑McMoRan and Southern Copper highlighted in other recent copper price pieces.

    Epiroc ET55 drill string: design, wear and energy-transfer notes for mine engineers

    Epiroc has launched the ET55 drill string, replacing the long‑running ST58 system and extending its ET next‑generation family with a fully shoulder‑drive connection from top hammer to bit. The ET55 applies the same design principles as earlier ET systems, using a shoulder drive interface along the entire string to improve energy transfer and reduce thread wear compared with conventional threaded couplings. For mine operators running top‑hammer production drilling, the unified shoulder drive geometry should simplify string configuration and potentially extend service life in abrasive ground.

    Redpath on Africa’s mining future: capability, data and safety notes for engineers

    Redpath Africa Operations Executive Pieter Oosthuysen argues that Africa’s mining growth depends on building local technical capability and systems, not just sinking new shafts into high-grade orebodies. He points to integrating digital mine planning tools with mechanised development fleets and rigorous safety management to lift productivity in deep, labour-intensive operations common across the continent. For geotechnical and mining teams, the message is a shift towards long-term skills development, data-driven decision-making and closer OEM–contractor collaboration on complex underground projects.

    Dyno Nobel autonomous blasthole system: design and safety notes for mine engineers

    Dyno Nobel has prototyped a fully autonomous, end-to-end blasthole inspection and loading system that removes personnel from the drill and blast bench, one of mining’s last highly manual and safety‑critical activities. Developed over five years of intensive R&D and unveiled to investors in New York, the technology autonomously orchestrates hole condition inspection, explosives loading and initiation sequencing. For mine operators, this points to tighter control of powder factors and timing, more consistent bench conditions, and reduced exposure of crews around loaded patterns.
