    Top 50 mining companies pass $2tn: valuation drivers and risks for project teams

    First reported on MINING.com

    30 Second Briefing

    Top 50 listed mining companies ended Q4 2025 with a combined market capitalisation of $2.17 trillion, up $892 billion year-on-year, driven by surging gold, silver and copper prices plus a weaker US dollar. BHP, Rio Tinto, Zijin Mining ($124bn), Southern Copper ($119bn) and Newmont now all sit above $100 billion, while Agnico Eagle has doubled to $86.3 billion and is edging towards that tier. Lithium and rare earth valuations remain volatile, with SQM and Albemarle re-entering the Top 50 as MP Materials and Lynas drop out, and the proposed Anglo–Teck combination worth just under $68 billion.

    Technical Brief

    • Market valuation uplift concentrated in H2 2025 after three years of sector-wide stagnation.
    • Near double‑digit US dollar depreciation inflated USD‑translated market caps on non‑US primary exchanges.
    • Fresnillo’s share price increased roughly five‑fold in 2025, securing a mid‑table Top 50 position.
    • Coeur Mining more than tripled in value in 2025 yet still dropped out after Q4 underperformance.
    • MP Materials’ Pentagon supply deal underpinned gains above 200% for the year before exiting the ranking.
    • Lynas Rare Earth doubled in value but also fell out, leaving China Northern Rare Earth as sole rare‑earth representative.
    • Western government funding support for mining, particularly from the US, is now explicitly framed as strategic competition with China.

    Our Take

    The outsized 2025 gains for MP Materials and Lynas Rare Earth line up with our other coverage of China’s rare earth export controls, suggesting investors are now pricing in a structural premium for non‑Chinese rare earth supply chains in the US and Australia.

    Agnico Eagle’s move to an $86.3 billion market cap after doubling in value echoes its strong showing in MINING.COM’s November Global Mining Power Rankings, which signals that both market performance and peer/investor sentiment are converging around large-cap gold as a preferred hedge in the current cycle.

    The surge in copper‑exposed names such as Zijin Mining and Southern Copper, alongside lithium and rare earth specialists, reinforces a pattern in our 2025 critical minerals coverage where assets tied to electrification metals (copper, lithium, rare earths, cobalt) have consistently outperformed bulk commodities like coal and aluminium in valuation rerates.

    Gold price in 2025: key mining and project risk takeaways for engineers

    Gold shattered records in 2025, setting 50 all‑time highs and reaching $4,549.71/oz on Boxing Day, while Basel III reclassified physical bullion as a Tier 1 high-quality liquid asset that US banks can count at 100% of market value. Barrick’s Loulo‑Gounkoto complex in Mali was twice hit by state seizures totalling roughly $245m and 35,000 oz, forcing shutdowns until a $430m settlement in November. Geopolitical tension over reserves intensified as Germany and Italy faced pressure to repatriate a combined 5,800 tonnes held largely in US vaults.

    Metso’s third orders for Almalyk copper smelter: design and ramp-up notes for engineers

    Metso has booked the third tranche of orders for JSC Almalyk Mining and Metallurgical Complex’s copper smelter project in Uzbekistan, following equipment and project services contracts announced on 9 August 2024. The first two tranches, totalling €146 million, were booked in Q4 2024, with the latest booking covering additional core process equipment and associated services for the greenfield smelter complex. The staged order intake signals a multi-phase build-out where process design, commissioning support and long-lead items will be critical for throughput, energy performance and sulphur capture compliance.

    Top stories of 2025 on MINING.COM: critical minerals and gold trends for project teams

    Critical minerals and gold dominated mining in 2025 as China’s export controls on antimony and rare earths triggered smuggling crackdowns, a 7,500-tonne US cobalt tender was cancelled and reissued, and MP Materials halted rare earth exports from Mountain Pass to China. The Trump administration pursued supply-chain security via a proposed critical minerals tariff probe, a US–Ukraine rare earths deal, and a December US–Congo partnership covering cobalt. Record gold prices above $4,500/oz, a Goldman poll pointing to $5,000/oz by end-2026, and De Beers’ first new kimberlite field in 30 years rounded out a volatile year.
