    US Mint–Colombia gold link: supply-chain and ESG risk notes for project teams

    US Mint–Colombia gold link: supply-chain and ESG risk notes for project teams

    First reported on MINING.com

    30 Second Briefing

    US Mint investor-grade coins have been linked to illegally mined Colombian gold controlled by armed groups and drug cartels, with material allegedly laundered through intermediaries and entering “US gold” supply under a loosely enforced domestic-offset rule unused for more than 20 years. Trade data show about $1.5 billion of Colombia’s $4.1 billion gold exports went to the US in 2024, while a WWF UK report found over 80% of financial institutions risk exposure to illegal gold. The US Treasury, which disputes the findings, has begun reviewing Mint procurement and tightening sourcing standards.

    Technical Brief

    • Federal law requiring “America-mined” gold for US Mint investor coins is being interpreted via an unenforced offset mechanism.
    • Accountability is fragmented: the Mint, primary suppliers and intermediaries each deflect responsibility for origin verification and due diligence.
    • NYT investigators documented laundering chains where Colombian gold controlled by armed groups is mixed and exported with falsified paperwork.
    • Previous enforcement cases involving Peru and Colombia showed illicit gold routinely entering North American refiners after commingling with legitimate doré.
    • Long, multi-step supply chains and repeated melting/refining cycles make physical origin tracing technically difficult once gold is aggregated.
    • For mine operators and refiners, the case underlines the need for auditable chain-of-custody systems and third-party assurance beyond minimal legal definitions.

    Our Take

    The finding that over 80% of financial institutions may be exposed to illegal gold mining dealings suggests that US- and UK-based banks financing gold traders will need much tighter KYC and chain-of-custody checks than those currently highlighted in most of our 461 gold- and rare-earths-tagged pieces.

    The 2024 watchdog report on US gold definition enforcement comes as our database shows only a handful of Mining–Sustainability stories involving rare earths and formal state buyers, signalling that similar scrutiny could extend to strategic minerals procurement beyond gold, particularly from Brazil and Kyrgyzstan.

    Minnova’s C$76M PL gold mine restart: economics and strip risks for engineers

    Minnova plans a C$76.2 million restart of the brownfield PL gold mine near Sherridon, Manitoba, targeting 62,200 oz per year over 10 years from a high‑grade open pit feeding an existing 1,000 t/d plant, which is slated to double to 2,000 t/d in year two. The September resource stands at 3.76 million measured and indicated tonnes at 4.98 g/t Au (601,158 oz) plus 1.67 million inferred tonnes at 3.78 g/t (202,810 oz), with open pits carrying a high 21:1 waste‑to‑ore strip ratio. At US$3,000/oz gold, the PEA projects an after‑tax NPV5 of US$180.6 million, 111% IRR, eight‑month payback and all‑in sustaining costs of US$2,288/oz, but value falls sharply at lower prices, underlining cost and strip sensitivity.

    Caterpillar Resource Industries leadership shift: fleet and autonomy cues for miners

    Caterpillar has confirmed that Denise Johnson, Group President of Resource Industries since 2016 and a key figure in expanding autonomous haulage and large mining truck platforms, will retire on 1 February 2027. Derrick York, currently President of Solar Turbines and a Caterpillar Senior Vice President overseeing industrial gas turbines and compressor sets, will become Group President of Resource Industries on 1 November 2026, with Johnson shifting to an advisory role. The handover timetable gives miners nearly a year of overlap to align major fleet, autonomy and support contracts with the incoming leadership.

    Anglo American copper scarcity and tech tie-ups: key takeaways for mine planners

    Tech companies are in talks to buy equity in Anglo American to secure long-term copper and other data centre metals, as Comex copper trades near $6.52/lb and LME cash copper recently hit a record $14,822/t. Anglo’s planned merger with Teck Resources would create a roughly $90 billion group producing about 1.2 million tonnes of copper per year, controlling around 5% of global supply, but is still awaiting Chinese antitrust clearance tied to concentrate flows to local smelters. Wanblad also warned Anglo may close its Brazilian nickel operations at Codemin and Barro Alto if the EU blocks the $500 million sale to MMG despite proposed long-term European ferronickel supply commitments.
