Precious Metal Ores, Gold, Platinum, Silver and Copper

Platinum ores nearly always form in strongly basic rocks that are also commonly rich in iron, chrome and nickel. Many of them form via some process of magmatic segregation from molten rock as it cools in the earth. Unlike gold and silver ores, platinum ores are almost never present in quartz veins.
