While this is an Australian standard it (and near equivilants) are the standards used on the largest mineral exchanges on the globe ( TSX et al )
The above 21 million tonne figure for Boliva is a best guess resource guesstimate and not an actual Proven Reserve estimate backed by sampling + geophysical survey + drilling + staged Technical Reports.
For that matter Iran here is asserting that they have an actual reserve backed by drill data and tech reports which leaves the question of:
