Micron gold

I know this might have been asked already but i was just wondering if anyone knows any good sites on finding and recovering micron gold from rivers and streams, and if it financialy viable?

that is where the money is.

most people dont find a bunch of nuggets but most do find flour and a few make a good living at it because there is more of the fine stuff out there.

Bump.  I too would like to know the most efficient way to recover micron gold.
