The 10 Most Impressive Mines on Earth
Every mine is a bet that moving rock will pay. These ten made the bet at a scale that bends belief — the deepest workings, the widest pits, the heaviest tonnages, and the boldest engineering ever put underground. Figures are approximate and current as of mid-2026.
| # | Mine | The superlative |
|---|---|---|
| 1 | Bingham Canyon — Utah, USA | Largest man-made excavation on Earth |
| 2 | Mponeng — South Africa | Deepest mine on the planet |
| 3 | Escondida — Chile | World's largest copper producer |
| 4 | Grasberg — Indonesia | Highest-value ore body ever block-caved |
| 5 | Muruntau — Uzbekistan | Largest open-pit gold mine |
| 6 | El Teniente — Chile | Largest underground network anywhere |
| 7 | Carajás — Brazil | Richest iron district on Earth |
| 8 | Kiruna — Sweden | The mine that moved a city |
| 9 | Chuquicamata — Chile | Century-old superpit gone underground |
| 10 | Oyu Tolgoi — Mongolia | Deepest new block cave of the modern era |
The rundown
Bingham Canyon — Utah, USA
Largest man-made excavation on EarthKennecott's copper pit runs roughly 2.5 miles across and about three-quarters of a mile deep — visible from orbit and still producing after more than a century. The 2013 Manefay slide, one of the largest non-volcanic landslides in North American history, happened here and the mine kept going.

Deepest mine on the planetGold workings reach roughly 4 kilometers below surface. Virgin rock runs near 60°C before refrigeration, so the mine circulates thousands of tons of ice slurry daily just to make the heat survivable. The trip from shaft collar to face takes over an hour.

World's largest copper producerThis BHP-operated giant in the Atacama routinely ships a million-plus tonnes of copper a year — more than most countries produce. It runs on desalinated seawater pumped 3,000 meters uphill from the Pacific.

Highest-value ore body ever block-cavedPerched at ~4,000 meters elevation in Papua's peaks, Grasberg converted from a monster open pit into one of the largest underground block-caving complexes ever built — pulling major copper and world-class gold from beneath a mountain.

Largest open-pit gold mineA Soviet-era discovery turned national engine: the pit stretches over 3 kilometers long and produces on the order of 2.5–3 million ounces a year — the top single gold operation on Earth.

Largest underground network anywhereMore than 4,500 kilometers of tunnels honeycomb this Andean copper mine — roughly the driving distance from New York to Los Angeles, all underground, caving continuously for over a century.
WIKI →▶︎ YOUTUBECarajás — Brazil
Richest iron district on EarthVale's Amazonian complex mines ore grading around 66% iron — so clean it needs little processing. The S11D expansion moves ore on a truckless conveyor system, cutting diesel out of the haul entirely.

The mine that moved a cityLKAB's underground iron giant undermined the town above it so thoroughly that Sweden is relocating central Kiruna — buildings, church and all — about 3 kilometers east. The ore body plunges more than 2 km and keeps going.
WIKI →▶︎ YOUTUBEChuquicamata — Chile
Century-old superpit gone undergroundAfter 100+ years and one of the largest open pits ever dug, 'Chuqui' converted to block caving beneath its own pit floor — a multibillion-dollar bet that its second century is underground.
WIKI →▶︎ YOUTUBEOyu Tolgoi — Mongolia
Deepest new block cave of the modern eraIn the Gobi Desert, Rio Tinto is caving the Hugo North deposit more than 1.3 kilometers down — a program so large it is reshaping Mongolia's entire economy around one ore body.
