I think the're cutting that nugget in parts so as to sell it to "Gold Traders" which I think they take advantage of them.That said the government knows all this it's all they care about is their sum that must be paid for them (the Authorites) to let any prospector work in the area or provide a "License" for your Metal Detector. That scene could not have been happening if they sell it to a collector, but that's another case.
