minerals occur at veins and lodes,sedimentary ore deposits,alluvial or placer depositsand by weathering.
You can go placer mining wherever gold is found in placer deposits. For gold, I'd suggest looking in Alaska, or California, or Arizona, though many other states also have gold in at least small amounts if you're willing to put in the effort. Montana is the state if you want to placer mine for sapphire.

Apparently alluvial diamonds migrate into placer deposits, being moved there by natural means, such as flowing water. Other materials are simply ground into tiny bits and ultimately 'placed' into the low spots in the geography. Sand is a descriptor used to name the quality of the tiny stones that make up most of the materials in placer deposits: some metal bits and alluvial diamonds are also found in placer deposits. You can read more about them, below.
