Is this a trick question?

As per CUU website and every NR:

"On receipt of a Positive Bankable Feasibility Study, a defined term in the Option Agreement, Teck has 120 days in which to elect to either: i) exercise one of its earn-back options, or ii) retain a 1% net smelter return royalty, or iii) receive common shares of Copper Fox to a value of $1,000,000."

Can this agreement just be broken? And why would CUU management want to do that? How could that possilby benefit the management/shareholders of CUU?
