Dirk,
All claims are either BLM or Forest service lands unless marked as public or lease, you can check the federal administrator of the claims in the title area in the Online Mining Guide or in the print guide as well. With that said, camping is allowed up to 14 days. this is a federal statute and not a GPAA policy. Many public areas restrict camping and it is advised that you check with the office in charge of the site before making the trip. this information is also listed in the Online Guide and Print guide in the regulations section.
I hope this helps.

Kevin
