Hi hunting. The latest fines come from someone's high banker leftovers. Just for fun, I washed 2 x 5 lit buckets Got 0.10 gram. In 100/200/300 mesh size. Always bring. Home some buckets and sieve / classify down to same size as sand. Using gold rat 6" at 5' slope and picking up the missed gold. Slow the water down to just flowing. Not to hard.
