"My understanding is that if Teck doesn't want to play by the rules as currently established, Copper Fox have every right to look elsewhere for a major to come in and start a mine...."
The Agreement says that if Teck decides not to exercise the option, they can receive, at their option, a 1% net smelter royalty or $1 M worth of CUU shares.
Or once CUU delivers the "Feasibility Notice" and a copy of the BFS, Teck has 120 days to decide which back-in option to choose. After the 120 days, Teck's back-in option and the first refusal right for the properties would expire. CUU would have 100% of SC and all the adjacent claims and the company would be worth a lot more. CUU can sell its assets to the highest bidder. That would be heaven to CUU shareholders. JMO
