    BHP–Amazon copper emissions pilot: EAC design and pricing notes for mine teams

    BHP–Amazon copper emissions pilot: EAC design and pricing notes for mine teams

    First reported on Australian Mining

    30 Second Briefing

    BHP and Amazon have launched a first-of-its-kind pilot linking copper from BHP’s Escondida mine in Chile to Amazon’s data centre and infrastructure demand via Environmental Attribute Certificates (EACs) tied to specific copper concentrate and cathode production. The trial will track and trade EACs that quantify lower greenhouse gas emissions across defined segments of Escondida’s supply chain, rather than relying solely on mine-level averages. For miners and downstream buyers, this tests a mechanism to monetise low-carbon copper at batch level and could influence contract structures, certification, and reporting requirements.

    Technical Brief

    • Mechanism centres on tradable Environmental Attribute Certificates tied to discrete Escondida concentrate and cathode batches.
    • EACs quantify greenhouse gas performance for defined supply chain segments, not whole-of-mine annual output.
    • Certificates are intended to be separable from physical copper, enabling independent trading and retirement.
    • Data requirements will include batch-level production records, logistics paths and emissions factors for each segment.
    • Verification will likely depend on third-party assurance of emissions calculations and EAC issuance/retirement records.
    • Commercially, EACs create a parallel value stream to LME-grade copper pricing without altering metal specifications.
    • Similar certificate structures could be adapted to other mining commodities where batch traceability is feasible.

    Our Take

    BHP’s work with Amazon on copper emissions at Escondida sits alongside its extended decarbonisation programme with China Baowu Steel, signalling that BHP is now targeting both downstream customers and major steelmakers with quantified low‑carbon offerings rather than just mine‑site efficiency projects.

    With global mined copper output forecast to fall in 2026, according to recent coverage citing Cochilco and the International Copper Study Group, verifiable low‑emission copper and cathodes from Chile could give BHP pricing and offtake leverage in a tightening concentrate and cathode market.

    In our database, BHP features heavily across the 1030 sustainability‑tagged mining pieces, and this copper‑focused pilot complements its battery‑electric haul truck trials in Australia, indicating that emissions data and electrification are being advanced in parallel on both the product and operations sides of its portfolio.

    Gold price slides on strong dollar: planning implications for mine projects

    Gold prices slipped to a one-week low as spot gold fell 0.4% to $4,271.16/oz in New York and December futures eased 0.3% to $4,306 amid a stronger US dollar and expectations of more hawkish US Federal Reserve rate moves. The dollar hit a two-month high and US 10-year Treasury yields hovered near a 20-year peak, sharply raising the opportunity cost of holding non-yielding bullion. Oil gained about 1% on stalled US–Iran talks over the war, while spot silver dropped 1.8% to $63.29/oz, platinum 0.2% to $1,746.44, and palladium rose 0.5% to $1,266.40.

    OceanaGold Waihi expansion: design, throughput and tailings notes for engineers

    OceanaGold is weighing a 50% expansion of its Waihi plant to 1.2 Mt/y after Wharekirauponga drilling returned standout intercepts including 6.3 m at 97.2 g/t Au from 481.5 m in the East Graben vein and 8.5 m at 41.5 g/t from 399 m. The move would enable concurrent feed from Martha Underground and Wharekirauponga post‑2032, building on a 2024 plan outlining 1.6 Moz over 15 years and an initial 4.1 Mt reserve at 9.2 g/t. Underground development is advancing, with the Waihi North decline now 350 m, first vent shaft under construction, staged commissioning of a new water treatment plant, and early works on a new tailings storage facility due in Q4.

    Kinross Gold output cut and higher AISC: operational drivers and FCF lens for mine teams

    Kinross Gold has cut its 2026–27 production outlook by about 8% to 1.84–1.86 million attributable gold-equivalent oz. a year and raised 2024 AISC guidance to $1,850–$1,900/oz after winter storms, copper-rich sulphide ore and poor recoveries at La Coipa in Chile, plus weaker mining rates, grades and recoveries at Round Mountain Phase S in Nevada. The company is stockpiling high-copper material, studying a new flotation circuit for deeper sulphide mineralisation that may overlie a copper porphyry system, and using a smaller shovel at Round Mountain to cut dilution. Despite the operational hit and a Q3 output cut to about 425,000 oz., Kinross has lifted its 2026 shareholder return target to 50% of free cash flow and has already returned about $800 million this year, mainly via $655 million in buybacks.
