The deepest hole ever drilled into the Earth reached just over 12 kilometres before the rock at the bottom turned so hot and plastic that it flowed back into the shaft, and for two decades of effort the drill had covered about two tenths of one percent of the distance to the centre
The deepest vertical borehole ever drilled reached 12,262 metres into the Kola Peninsula in 1989. Work had begun in 1970. By the time active drilling ended in the early 1990s, the Soviet project had advanced about 0.19 per cent of the distance from Earth’s surface to its centre.

A mine is more than a hole in the rock
INTIMIDANT! The deepest “hole” on Earth that could swallow Everest without leaving a trace.
