It all really depends on how tight his budget is for this project.
This will push back any prospect of commercial operations by 2 years at least - does he have cash to fund it through? What will the delay do to the NPV of the project and will it be able to recover? Is he prepared to take the risk while sinking more capital into it or is he going to cut the losses and stop?
