This has been mentioned once before but it doesn't hurt to visit it again.

The authorities go by actual stakes in the ground and not the description that might be entered in the registry. No question but a review of actual stakes can change the line of division between neighbouring claims. It's not likely to be that big of a deal, normally, but if that mineralization goes from Noronts property continuously over FNC's property it is a big deal. Even 50 meters can be valuable if underlain by rich ore.
