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

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.
