How to read the table
Every figure is copied from the company's own release, in its currency and on its basis. The line under each figure gives that basis, for example post-tax or pre-tax NPV and the discount rate.
"Not disclosed" means the release doesn't state the figure. Where a release states a figure in a way that contradicts itself, or labels it in a way we can't interpret, we leave the figure out and list only what we could confirm.
"Inferred share" is the share of the production target or mining schedule that comes from Inferred Mineral Resources, as the company reports it.
Each row links to the company's own copy of the release. Read the release before relying on any figure.
