......."IOC has stated that it is looking at expansion plans moving from 18mtpa current capacity (sales in 2012 at 14.1 according to Rio Tinto figures) and planned expansions are to 22 then 26 mtpa.".......
 

FWIW, The Labrador Iron Ore Income Corp stated in Q4 2012 that the Concentrate Expansion Project Phase 1 was turned over to operations in August, 2012 - so IOC nameplate now should be at 22 mtpa.

Like all other new start-ups we can expect some growing pains I suppose - it will likely take awhile to integrate the expanded capacity and boost production.
