    BHP–Amazon low-emissions copper pilot at Escondida: pricing signals for mine planners

    September 23, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    BHP and Amazon have launched an “industry-first” pilot to trade credits linked to lower greenhouse gas emissions from copper concentrate and cathodes produced at Escondida, the world’s largest copper mine in Chile. Escondida already sources 100% of its electricity from renewable power contracts and uses desalinated water for processing, reducing Scope 2 emissions intensity relative to conventional operations. The pilot will test traceable, emissions-differentiated copper units in Amazon’s supply chain, signalling potential future premiums and contract structures for low‑carbon copper in OEM and data centre procurement.

    Technical Brief

    • Contract design must define baselines for “conventional” copper emissions intensity to quantify the lower‑emission delta.
    • Verification will rely on mine‑level energy and water sourcing data, plus third‑party assurance of emissions calculations.

    Our Take

    In our database, BHP’s work with Amazon on lower-emissions copper from Escondida sits alongside its extended decarbonisation programme with China Baowu Steel, signalling that BHP is now trying to embed emissions-linked attributes across both its copper and iron ore customer base rather than treating them as isolated pilots.

    The copper market note in our coverage highlighting the first annual mined copper output decline since 2017 suggests that any verifiable low‑emission copper units from Escondida could command a premium or preferential offtake positioning as OEMs and data-centre operators compete for constrained cathode supply.

    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.
