No one minds answering questions about technical details but the tenor of the questions asked was  really dumb, imho. I mean 'why so many companies involved?'

It's exploration and if someone can put people on the ground and stake mining claims then more power to them. Still have to find mineralization of economic value.

In many ways our system works better than most as no one company gets blanket exploration rights to Ontario Crown Land. Anyone can stake unclaimed land, register said claim or claims and if they spend money on exploration/development of the claims keep them current. If no money is spent to keep the claims current then they will eventually revert to the Government and someone else can pick them up.
