Platinum
Platinum exists in higher abundances on the Moon and in meteorites. Correspondingly, platinum is found in slightly higher abundances at sites of bolide impact on Earth that are associated with resulting post-impact volcanism, and can be mined economically; the Sudbury Basin is one such example.
Unki mine
The Unki mine is an underground mine located in the center part of Zimbabwe in Gweru, Midlands Province. Unki represents one of the largest platinum reserves in Zimbabwe having estimated reserves of 34 million oz of platinum. The mine produces around 64,000 oz of platinum/year.
