Just thought if bedrock do you clean out the crevices manually as a lot of au would be down where the Excav cant dig.

Ag Man said:Where there's no bedrock, gold usually settles only as deep as hard clay. Now, trying get gold out of this top layer of clay is tricky - even getting some of the softer clays to break up can test you.
What are some methods you use for breaking up larger volumes of clay?
A couple of mates & me been thinking of making a trommel.
