Quick Fact
The world's single largest gold mine by production is the Grasberg Mine in Papua, Indonesia.
As of 2026, this monster operation has churned out over 50 million ounces of gold. That’s not all—it’s also delivered more than 30 billion pounds of copper since they first struck ore back in the day.
Geographic Context
The Grasberg Mine sits at 4°03′10″S 137°06′57″E in Indonesia’s Sudirman Mountain Range.
This place isn’t just remote—it’s at over 4,270 meters (that’s 14,000 feet for us non-metric folks) up in the mountains. We’re talking extreme engineering here. And get this: it’s smack dab in the Pacific Ring of Fire, which explains why this spot’s packed with so much mineral goodness. Honestly, it’s one of those rare places that’s as important for copper as it is for gold.

Interesting Background
The Grasberg Mine’s discovery in 1988 followed the earlier Ertsberg (Ore Mountain) find from the 1930s.
Talk about a modern-day gold rush. The scale of this deposit didn’t just make headlines—it reshaped the entire mining game. But it’s not all shiny ore. The operation’s environmental impact in that fragile alpine ecosystem has drawn serious scrutiny. According to a National Geographic report from 2021, you can actually see the scars of excavation from space. That’s how massive this thing is.
Practical Information
Access to Grasberg is tightly controlled because it’s a working industrial site in an extremely remote location.
Don’t expect a tourist visit. Special permits? Check. Coordination with Freeport-McMoRan? Absolutely. The high-altitude, rugged terrain doesn’t exactly roll out the welcome mat. For the average gold enthusiast, you’ll have to settle for tracking its production numbers—because those move markets. Right now, the mine’s in the middle of a big shift, moving from open-pit mining to underground block caving to chase deeper ore. The details? Check out the technical reports from Freeport-McMoRan.
