30 Second Briefing
Market value of the top 50 mining companies jumped by $357 billion in August, taking the group back above $2.5 trillion as gold hit nearly $4,660/oz and copper briefly topped $14,000/t. Gold, silver and royalty stocks contributed $183 billion of the gain, with Newmont and Agnico Eagle each now above $100 billion and AngloGold Ashanti up 41.6% after a 58% Q2 profit rise and a $2 billion buyback. Copper-focused majors surged as Southern Copper temporarily overtook Rio Tinto, BHP’s copper earnings surpassed iron ore, and twelve copper names added $70 billion, while iron ore-exposed Fortescue and Vale lagged.
Technical Brief
- Gold, silver and royalty counters jointly delivered $183 billion of the August value increase.
- Gold miners alone added $138 billion in market cap, a 31% rise in four weeks.
- AngloGold Ashanti’s 41.6% gain equated to nearly $17 billion after a 58% Q2 profit jump and $2 billion buyback.
- Southern Copper briefly exceeded Rio Tinto with a ~$183 billion valuation at $220.78/share before copper’s late pullback.
- Twelve copper-focused companies together gained $70 billion; Freeport-McMoRan is now 47% higher year‑to‑date.
- BHP’s copper division overtook iron ore as its largest earner in the full-year results it reported mid-month, supporting a 57% rise for 2026.
- Polyus trades at roughly $6,000 per annual ounce versus ~$23,700 at Newmont and ~$30,000 at Agnico Eagle.
- Entry threshold to the top‑50 rose to $15.6 billion, up from $13.6 billion a month earlier, accelerating index turnover.
Our Take
AngloGold Ashanti’s sharp rerating comes on the heels of fresh growth moves such as its August investment in Thesis Gold & Silver, indicating that some of the value uplift is being underpinned by a visible pipeline of exploration and development options rather than price beta alone.
With copper-focused names like Southern Copper, Freeport-McMoRan and Glencore driving a sizeable portion of the $70 billion copper sector gain, the rally reinforces what other 2026 items in our database show: copper remains the dominant decarbonisation metal in investor positioning, outpacing newer battery commodities such as lithium in recent market attention.
