I think it was California well during the 1800 in goldmines. Maine, New Hampshire, Rhode Island and Vermont could be candidates, but the quantities were very small and no significant mining was done. (Gold, as it turns out, can be found in most all of the fifty stated, but, again, the concentrations are not significant.) The Georgia gold rush in 1829 preceded the California gold rush by almost 20 years.

Facts about platinum?
Platinum is a metallic element with the chemical symbol Pt and an atomic number of 78. Its name is derived from the Spanish term platina del Pinto, which is literally translated into "little silver of the Pinto River." It is a dense, malleable, ductile, precious, gray-white transition metal. Platinum is one of the rarest elements in the Earth's crust and has an average abundance of approximately 0.005 mg/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. Some counterfeiters in the late 1500's made coins in South America from platinum that resembled silver coins (at the time platinum was unknown and not valued) The authorities confiscated the coins, set them on a ship out to sea in the Pacific and scuttled the ship. It sank in an unknown location. Today that trove of platinum would be very valuable.
