The deepest mine in the world is AngloGold Ashanti's Mponeng gold mine, near Johannesburg in South Africa.

By 2012, the operating depth had already reached 3.9-km below the surface, and later expansions have resulted in digging below the 4-km mark.

The deepest man-made hole in the world is ~12 km called the Kola superdeep borehole in Russia.
