Hello Stratopod,
I only rely on Google Earth in conjunction and overlaid with the MNDM's real-time (updated every few days) unpatented mining claims data base that includes all Ontario mining claims, alienations and dispositions.
I know every claim number and where they are held of KWG, CCC, Debut Diamonds, Cliffs, Noront, Probe, and all other main players and prospectors in the ROF including all jointly held unpatented mining claims and their locations from Aroland, Exton and Nakina all the way up to the ring.
I would be happy to share my information but perhaps the most practical way for all of you to benefit is to request a specfic area map. My work is very acurate and detailed.
