They are planning to do a IPO of their Casa de Piedra mine, which is one of their crow jewels as the quality and reserves of the iron mine are impecable. It putting a value on their mining operation just as they did last year with the sale of 40% of another of their mines. They are also contemplating the IPO for their logistics division but due to market conditions I don't think it will happen in 2010 (for that division). As for their Casa de Piedra it will unlock lots of value for the company and shareholders. I found the following article where the CEO talks about the potential IPO of Casa de Piedra.
