This publication provides an overview of aspects of the uranium production cycle including evaluating the global uranium supply/demand situation. It presents insights on techniques for analysis of undiscovered resources for mineral commodities, which has formed part of a robust statistical procedure in the last 20 years, but has never been systematically applied to uranium. For this publication, experts have carried out case studies on speculative or undiscovered uranium resource potential, systematically applying spatial assessment techniques often with non-spatial quantitative techniques. This publication is the result of the work contributed by those experts over the period 2014–2016 and provides the tools for Member States to investigate and evaluate undiscovered uranium resources and deposits.
