The impact crater was located near the historic Goldfields mining town of Ora Banda, north-west of Kalgoorlie-Boulder, while drilling for gold.

It is not visible from the surface but electromagnetic surveys, which map the rocks below, suggest the crater has a diameter of around 5 kilometres.

Perth-based geologist and geophysicist, Jayson Meyers, said the asteroid that made the crater would have been at least 100 metres wide.

"Based on its position and levels of erosion and some of the soil that is filling the sides, we estimate it could be around 100 million years old," Dr Meyers told the ABC.
