I am curious abt this as well. Simple math says the marginal value of adding 100% of the 171Mt of inferred at its respective grade and with the same processing cost and recoveries as in the BFS is $1.48B (undiscounted). This is the most the inferred could be worth and accounts for the mining costs having being already paid in the BFS. Now take $1.48B and subtract incremental capex of increasing capacity, discount the new revenue and cost appropriately and you probably get somewhere in the $300-600M range for the inferred imo. You can probably to a better estimate once the BFS is filed and you can see the mine plan. Curious what others think.
