RE:Hi cost Zn producer ?There are no other pure Zn producers of this caliber (top 10 in the World).
Larger zinc producers (example Teck) have lower costs as they are managed better and have world class deposits (Red Dog). Largest Zn mines in the World are open pit operations, they have much lower costs and more flexibility to ramp up production when the Zn price goes up.
If Zn price goes up by another 10c/lb, TV will make good money. If the Zn goes above $1.5/lb and stays there for a longer period of time, they will make a lot of money.
