"but the project either would need to stack up on the minimum price level"

Seriously? Go read the DFS. Was based on $539/tonne. Floor price of this BOA is $550/tonne. i.e minimum floor is above the feasibility study, i.e proof the project is economically viable.

Payback period from the DFS is 1.8 years. Floor price is in place for 3 years. i.e they have almost twice the time they need to payback any debt at the floor price.

Based on current prices they will be able to pay debt back in essentially a single year.
