I like your analogy to fishing. I fly fish barbless now after many years of filling the freezer...:)
Economical is the key term here IMHO.
We must keep in mind that some of these major Chrome suppliers are from S. Africa and I have read that some are down 4 miles. They are so close to hell that they require Air Conditioning in order to work. The problem is that the Hydro is intermittent.
The ROF is predominantly open pit and of course Thunder Bay has all the hydro that will be required as has been mentioned before.
Open pit, Hydro, excellent work force. Some of the best in the world. The quality of the deposits is next to perfection with great numbers. More than 100 mil???
This makes the ROF much more economical even when you toss in a road.
