If gold dissolves in water, how come one can pan for it in streams?

I don't know its solubility, but there is about 55 pounds dissolved in
a cubic mile of seawater. Water is close to a universal solvent :-)

I'm interested in a method of extraction from a cubic mile of seawater
as I have this (or at least the edge of same) just outside my front
door. Any references?
