    The precious-metal group consists of gold, silver, and the platinum-group elements (PGE). The worlds leading producer of gold is South Africa, followed by the United States and Australia. Most mining of gold is done specifically for that metal rather than for a polymetallic assemblage, and most gold is produced from auriferous quartz veins.

    How to Identify Platinum in Ore Deposits | Sciencing

    The largest platinum deposits reside in Russia, South Africa and Zimbabwe, with smaller deposits in Canada and the United States. In South Africa, where the greatest mine production occurs, the mineral cooperite represents a chief source of platinum. The geological structure for the ore in South Africa is an intrusion called the Bushveld Complex.
