There are six Platinum Group Metals that, although rare, are often found together in a mineral deposit. They include platinum, palladium, rhodium, iridium, ruthenium and osmium – each with their own characteristics that make them uniquely suitable for various applications. Approximately 50% of global palladium production comes from platinum mines; however, there are two primary palladium mines: Stillwater and Lac des Iles.
