Platinum
Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust, with an average abundance of approximately 5 μg/kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for 80% of the world production. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity.
Zimbabwe
The mining sector remains very lucrative, with some of the world's largest platinum reserves being mined by Anglo American plc and Impala Platinum. The Marange diamond fields, discovered in 2006, are considered the biggest diamond find in over a century. They have the potential to improve the fiscal situation of the country considerably, but almost all revenues from the field have disappeared into the pockets of army officers and ZANU-PF politicians.
