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.
Kroondal mine
The Kroondal mine is a large open pit mine located in the north-western part of South Africa in Rustenburg, North West. Kroondal represents one of the largest platinum reserves in South Africa having estimated reserves of 6.2 million oz of platinum. The mine produces around 217,000 oz of platinum/year.
