Our transcription: Metallic minerals, such as gold, and silver, and copper all form the same way; they're precipitated from very hot water solutions called "hydrothermal" solutions that percolate up through cracks, up through fissures in the Earth, and as they reach cooler regions, they begin to crystallize, and whatever metals and non-metals that are in, dissolved in that hot water, precipitate out. In case of gold, or silver, or copper, it calls for very special waters, and that's why they're all very rare.
