It is true that it did not cost them a lot to be able to explore and find good spots with high alumina %.
We must also remember that when they expanded their claims by about 10 times, that whole expansion cost them only... 60 THOUSAND dollars ! THAT's what I call not expensive. They have been doing work on these new claims, and the results will be in the BFS. The Saint-Apollinaire ones are especially interesting if they prove to be exploitable.
I really like those % numbers in the thirties in NS. :-)))
