[QUOTE="goldtrapper, post: 487271, member: 13646"] Quote Goldierocks, "Many people assume that gold cannot dissolve in near-surface cold water, Incorrect. In desert areas, the water is often highly saline (e.g. tens of percent dissolved salt - ordinary table salt in composition). Gold dissolves readily in this near the surface, where there is also plenty of atmospheric oxygen. The dissolved gold then moves through the soil in groundwater and weathered rock until it meets up with some carbon or iron, then it dumps out again as metallic gold, sometimes as nuggets (so some gold nuggets actually form in the soil). The original gold may have a lot of contained silver, but the new gold in the soil is almost pure gold." I remember seeing a picture of a nail that was found gold plated in a creek near an old gold field in NZ. [/QUOTE]
