This FS includes lots of forward thinking Nordmin seems to have brought a whole new approach to this. The section you have highlighted is one example of this. I am encouraged that there are many more such examples. The section walterc posted yesterday is another. They can adjust what areas they mine based on market prices. They can adjust the Nb/Sc ratio if desired. Both main and vent shaft will be the same diameter and each can be used for the same functions. Suppose you want to sink the main shaft deeper (because maybe you discovered high grade ore deeper.) You have $400 million worth of processing facilities and staff to operate it. You do not want to shut all that down while sinking the shaft deeper. No problemo: use the vent shaft as your production shaft. And then in the "thinking outside the box category" we have electric trucks. This mine will have huge ventilation fans. They will be driven by electric motors that might well be over 1000 hp. The main reason for needing a LOT of ventilation is a fleet of underground diesel powered trucks. Nordmin suggests that technology might advance to the point that electric trucks are feasible. The need for ventilation and the electricity used by these fans will go way down. This all strikes me as very competent and practical design engineering. Nordmin has designed a mine that will give Niocorp lots of flexibility and allow them to adjust to changing markets and technology advancements.
