I strongly recommend you go there to get the full picture. There's also an excellent list of rivers and creeks etc, but I'm unsure of the legalities of prospecting in them as that's a bit obscure. It says something about Q3, but that doesn't really refer to the list.
I printed the first part of this down to the end of the number 6. It makes for handy reference.
Finally, there's a comprehensive list of MINER'S RIGHT agents, so there's no excuse for not getting one, and
fill in ya friggin holes.
Catch ya around the cracks,,,, er,, I mean traps.
Cheers, Ron.
