30 Second Briefing
World’s 50 most valuable miners reached a combined market capitalisation of $2.17 trillion at end-July, with entry to the list now requiring $13.56 billion, more than four times the $3.2 billion threshold in 2020. China’s Zijin Mining surged 23.8% to $125 billion on guidance for a 68% jump in first-half net profit and a sixfold increase in lithium output to 43,000 tonnes LCE, while Russia’s Polyus slumped 37.6% after suspending dividends until 2030. Glencore’s adjusted H1 2026 EBITDA rose 86% to $10.1 billion, supported by a 15% copper output increase and volatile oil trading.
Technical Brief
- Market cap spread between individual 2026 highs and lows across the Top 50 reaches $545 billion.
- Zijin’s H1 guidance includes gold output up 15% to just over 1.5 Moz and silver to 7.4 Moz.
- Polyus’ dividend suspension to 2030 follows record earnings and c. $2 billion free cash flow last year.
- Polyus’ share price fell 26% in one session, its second-worst day after 16 September 2008.
- Shandong Gold’s peak‑to‑trough drawdown exceeded 60% before value buyers entered at ~10x earnings.
- Western Mining secured 50th place after a 41.5% monthly gain; record entry threshold nears $14.5 billion.
- South32’s $2 billion‑plus Hermosa zinc‑silver‑manganese project in Arizona targets first production in early 2028.
- Post‑Alcoa sale, Cannington’s silver‑lead‑zinc output will exceed 10% of South32 revenue, leveraged to ~$60/oz silver.
Our Take
Glencore’s 86% jump in first-half adjusted EBITDA and 15% copper output growth, alongside Rio Tinto’s treatment as a diversified ‘metals plus iron ore’ house, echo May coverage that linked record copper prices to AI-driven demand; this combination of earnings leverage and exposure to copper, cobalt and nickel is likely what keeps diversified majors at the top of the ranking despite precious-metal swings.
South32’s decision to sell almost all of its aluminium business to Alcoa while pushing ahead with the $2+ billion Hermosa zinc–silver–manganese project fits a pattern in our Projects-tagged coverage of operators rotating out of mature bauxite/aluminium chains into higher-multiple critical minerals such as manganese and zinc, particularly in US-linked jurisdictions like Arizona.
