    Antofagasta’s Arriagada returns as ICMM chair: tailings and ESG priorities for engineers

    Antofagasta’s Arriagada returns as ICMM chair: tailings and ESG priorities for engineers

    First reported on MINING.com

    30 Second Briefing

    Antofagasta CEO Iván Arriagada has been re-appointed chair of the International Council on Mining and Metals (ICMM) for a two-year term, succeeding Newmont chief Tom Palmer, who is retiring as CEO at year-end. Arriagada, who previously chaired ICMM from 2022–2024, helped establish the Global Industry Standard on Tailings Management and backed the Consolidated Mining Standard Initiative (CMSI) on common ESG benchmarks. His return signals continuity in ICMM’s 26-member CEO council as it executes its 2025+ strategy on tailings governance and responsible project development.

    Technical Brief

    • ICMM council structure centres on 26 member-company CEOs, with the chair selected exclusively from this group.
    • Chair tenure is explicitly time-bounded to roughly two years, constraining continuity of leadership cycles.
    • Leadership change is triggered here by Newmont CEO Tom Palmer’s retirement at year-end, not by policy shift.
    • Rohitesh Dhawan, as ICMM CEO, separates executive management from rotating chair oversight, clarifying accountability lines.
    • Public statements link Arriagada’s leadership to “industry performance and sustainability initiatives”, embedding ESG into ICMM’s core mandate.
    • Tailings management and ESG standardisation are framed as multi-year programmes aligned to ICMM’s “2025+ strategy” timeline.
    • For project developers, ICMM’s emphasis on common standards signals tighter convergence of member-company requirements on tailings and ESG reporting.

    Our Take

    With Antofagasta Plc heavily exposed to copper in Latin America, Arriagada’s renewed ICMM chair role comes as our recent coverage shows a wave of new copper project approvals in the region, such as the PSJ Cobre Mendocino project in Argentina, sharpening scrutiny on how ICMM standards are applied on the ground.

    The ICMM’s 26 member companies include major gold and copper producers like Newmont, so Arriagada’s two‑year term will likely influence how sustainability and standard-setting debates play out for assets similar to those in the Rio2–Condestable copper-gold transaction reported this week.

    Congo’s cobalt sector, referenced in our database through quota-related policy pieces, is a likely pressure point for ICMM under Arriagada, as expectations grow for clearer guidance on responsible sourcing of cobalt alongside copper and gold in high‑risk jurisdictions.

    AME call to appeal Gitxaala decision: tenure and permitting risks for miners

    The Association for Mineral Exploration is urging British Columbia Premier David Eby to appeal the Gitxaala Nation v. British Columbia decision, after the province’s Court of Appeal ruled on 5 December that the Declaration on the Rights of Indigenous Peoples Act incorporates UNDRIP and creates legally enforceable obligations. AME argues the ruling creates uncertainty for the province’s automatic online mineral claim system and the Mineral Tenure Act, despite the March 2025 Mineral Claims Consultation Framework (MCCF) changes. The group wants the legislature recalled to make “substantive” amendments to DRIPA and section 8.1 of the Interpretation Act before a 16 February 2026 appeal deadline.

    Korean study on Latin America lithium playbook: project strategy notes for miners

    Korean researchers led by Seungho Lee at Jeonbuk National University map five distinct lithium governance models in Chile, Argentina, Brazil, Bolivia and Mexico, linking them to commodity price cycles, geopolitical competition and the maturity of each country’s lithium industry. Chile’s hybrid regime with strong state oversight contrasts with Argentina and Brazil’s decentralised, market-led systems, Bolivia’s tightly controlled state-led model and Mexico’s largely rhetorical nationalisation stance. The two-stage decision-making framework signals that miners, battery manufacturers and state-backed investors must tailor project, offtake and JV strategies to country-specific political settlements rather than apply a single Latin America playbook.

    Engineers again rank second most trusted in UK: risk and safety mandate for projects

    Engineers have again ranked as the UK’s second most trusted profession in the 2025 Ipsos Veracity Index, with a large majority of respondents saying they believe engineers tell the truth. The result places engineers just behind nurses and ahead of doctors, teachers and scientists in perceived honesty. For infrastructure and construction teams, this public confidence strengthens the mandate for engineers to lead on risk communication, safety decisions and major project trade-offs in areas such as flood defences, transport schemes and energy infrastructure.
