    Gold, silver, copper price plunge: risk and project signals for mine planners

    Gold, silver, copper price plunge: risk and project signals for mine planners

    First reported on MINING.com

    30 Second Briefing

    Billions were wiped off mining equities as gold, silver and copper all entered technical bear markets, with gold futures dropping $225/oz on Friday to $4,492/oz (down over 20% from the 29 January peak), silver sliding 44% from its high and copper losing nearly $2,800/t from its record. Newmont, Barrick and AngloGold Ashanti are down 26–37% since the Iran war began, while copper-focused majors such as Freeport-McMoRan, Southern Copper and First Quantum have fallen 23–31%, despite growth projects like Freeport’s proposed $7.5 billion El Abra expansion to add 300,000 t/y of copper. Glencore is the notable outlier, off only 4.3% since hostilities started and up 25.6% year-to-date, supported by trading around 4 million boe/d and exposure to surging coal and oil prices.

    Technical Brief

    • Newmont’s New York market cap has fallen from $143 billion in January to $104 billion.
    • Barrick’s valuation is down $27 billion over the same period, now sitting at $62 billion.
    • Anglogold Ashanti, Gold Fields and Kinross now sit at roughly $40b, $35b and $32b market caps respectively.
    • Silver-focused Fresnillo and Pan American Silver have dropped to about $30 billion and under $20 billion valuations.
    • BHP has lost 20% from a record $213 billion valuation, despite reporting record profits and strong Chinese demand.
    • Rio Tinto’s 16.3% share decline to $143 billion comes as it commits $500 million to Resolution’s drilling.
    • Freeport’s market value has retreated from briefly $100 billion in February to $74 billion after heavy trading.
    • Zijin Mining’s US units are down 30.2%, yet it remains the fourth most valuable miner at $123 billion.

    Our Take

    The same set of gold and copper majors hit in this sell-off—Newmont, Barrick, AngloGold Ashanti, Freeport-McMoRan and others—were highlighted in our 26 February producer rankings piece as beneficiaries of a 2025 gold price surge, underscoring how quickly equity valuations are whipsawing around macro and conflict headlines rather than mine-level fundamentals.

    With copper still around $5.3/lb despite a 7.4% weekly decline, large capex items like Freeport’s planned $7.5 billion El Abra expansion and Rio Tinto’s $500 million Resolution drilling campaign remain in a price environment that historically has supported long-life project sanctioning, but boards may now face pressure to re-test downside cases and timing.

    The earlier 4 March coverage of the Iran–US conflict already showed these same diversified houses (BHP, Glencore, Rio Tinto, Vale, Anglo American, Teck) trading more on macro risk than on individual project news, which likely means near-term project pipelines in Australia, Canada and Chile will be managed with tighter capital discipline and higher return thresholds until volatility eases.

    pH7 Technologies’ closed-loop PGM and chalcopyrite leaching: key notes for mine planners

    Canadian processor pH7 Technologies is expanding its Vancouver facility, backed by up to C$4 million from NRC IRAP, to scale its organo-electrochemical platform that recovers platinum, palladium and rhodium from secondary materials without toxic reagents or tailings wastewater. The commercial plant already processes spent catalytic converters, producing 30,000–40,000 oz of platinum-equivalent PGMs per year under a tolling and offtake model involving partners such as Mitsubishi. pH7 is now piloting electrochemically generated oxidants to heap leach chalcopyrite and other sulphide ores without cyanide, targeting on-site mine deployment within 1–2 years across South America, Africa and Australia.

    Dellner Bubenzer mining brakes: integrated drivetrain design notes for engineers

    Dellner Bubenzer is supplying a wide range of industrial brakes and couplings for mining hoists, slewing drives and belt conveyors, developed in long-term collaboration with OEMs. The company focuses on both service and emergency braking solutions tailored to heavy-duty mining duty cycles and harsh environments, addressing controlled hoisting, precise slewing and high-tension conveyor stopping. For engineers, the key point is an integrated approach to drivetrain and braking design, rather than bolt-on safety systems, across multiple critical mining applications.

    SKRI ‘phytocapture’ at Raygorodok: dust control performance insights for mine engineers

    China’s Zijin Mining is expanding RG Gold’s Raygorodok operation in Kazakhstan with a $500 million processing plant while deploying SKRI’s ‘phytocapture’ system, planting over 100,000 Scots pines across more than 20 hectares about 1.7 km downwind of the open pit. Supercomputer modelling using regional wind-rose data sets tree species and spacing to form multilayered vegetative barriers, not simple landscaping. SKRI reports particulate-matter reductions above 40%, with the forest belt expected to capture roughly one-third of dust emissions as mining advances towards the barrier.
