And just how is he going to get 100 million kilos

That's just one of the many technichal difficulties with this scheme. I think I have the answer, though.

You could put a refractory dam around the hole where you want to dump the iron. Inside this dam, pile up a small mountain of powdered aluminum/ferric oxide mixture. Add one strip of magnesium ribbon to ignite, and voila! A thermite reaction yeilds a swimming pool full of molten iron toot sweet, baby.

I wouldn't stand too close, though.
