Thanks for the question. I appreciate the concern.
The best practices are that you need to spend 5% to 10% of your potential cost to have a detailed estimate. That's how big projects get done. If you look at the recipe, what's been done elsewhere and the book that was written on it, you need to invest at least 5% to 8% or 10% of it.
We're not there yet. That's why having the alignment later in the year and detailing the engineering and getting the permits is very sensitive before presenting a budget estimate. Before next year, I won't be in a position to have a budget estimate because sufficient work has not been done.
