How can gold atoms created during a supernova assemble to form lodes in the earth crust?

When I visualize a supernova, I imagine all created atoms are dispersed pretty much evenly across the blast radius, how come several billion years later, they all are concentrated in specific spots in the earth's crust? (Off course,  this goes for a lot of other elements.)

Gold doesn't naturally form in nuggets, rather, it is carried in other chemical bonds within hot water until the conditions become good enough to precipitate the gold out of solution. To have the hot water, you usually need to be near a volcano. If you look at California and Alaska, they have a massive amount of volcanoes and other magmatic products, and, they also have a lot of gold.
