Re the $1B figure - Possible its there, and possible its more if vanadium is also recoverable from the tailings, but of course only 40% is ours. A bit more detail wouldn't go amiss.
But from the detail so far, they've told us (from BMR estimates) that:
1. there's around 6.4m tonnes of tailings at surface.
2. two of the piles (about half of the tailings, or 3.2M tonnes) contain 272k tonnes of lead, and 163k tonnes of zinc
3. tests have shown recovery rates possible at varying levels for the different metals and tailings piles.
Using these amounts and possible recovery rates given leaves:
1. 221k tonnes of lead, at todays prices about �400M in value
2. 99k tonnes of zinc, at todays prices about �250M in value.
So I make it as about �650M in possible revenue (not profit) sitting there, not taking into account the remaining 3M tonnes of tailings or vanadium.
What we don't know is what profit we could make per tonne after the cost of processing the tailings, and over what time scale. And of course we don't know if what we produce will need further refinement that either adds extra cost or reduced earnings per tonne.
But whatever it ends up being, some large numbers do not look impossible on this project.
