Mineral resources and ore reserves explained

A resource update describes an estimate, its confidence and its assumptions. Read the classification and supporting detail before comparing the headline tonnes or contained metal with an earlier estimate.

  • Check the confidence category. Inferred, Indicated and Measured describe increasing geological confidence. Keep the categories separate when comparing estimates; a larger total can contain a different mix of confidence levels.
  • Distinguish a resource from a reserve. An ore reserve is the economically mineable part of a Measured or Indicated resource after relevant mining, processing, economic and other factors have been considered. A resource does not automatically become a reserve.
  • Compare the same basis. Check the reporting date, ownership share, grade and cut-off assumptions, and whether resources include reserves. A change in the reporting basis can affect a comparison even without a new discovery.
