Early on, there was a staking rush in the ROF area.
Over time, several option agreements expired and a couple companies were taken out....like FWR and SPQ.
Although Noront holds bout 85% of the claims, there are some nearby companies that continue to hold their claims, some of which have provable resources.
FNC holds a 50% interest in claims right next to the eagle's nest deposit after optioning off the other 50% to Bold/KWG. PRB also has some high ground with a chrome resource and I believe BMK still has some claims and royalty interests after selling off some to Noront.
