Copper mining began at Palabora in 1965, and by 1967 the open-pit mine was fully operational. The hole reached 800 meters down into the Earth before the depletion of resources made it uneconomical to continue mining in the pit. Operations moved underground (below the pit) and mostly out of sight in the early 2000s.

Blasting and grinding equipment are used to accomplish this task. Open pit mining is a technique used to extract copper ore near the earth's surface.
