Ann: COMMENCEMENT OF OPERATIONS AT THE CENTURY ZINC MINE, page-12

They're looking at somewhere around 150kt Zinc for the next 12 months during the ramp up from what I gathered from the Presentation
At $1.25/lb and $0.45/lb cost
I would say they could pull between $200-$300m profit before tax in the next 12 months

I don't hold yet, I think I will soon however.
Only thing that irks me is the ~20% dilution in unlisted securities
MC is more like $720m

Lots of potential here. Will be a real earner if it all comes together
