Uranium Identified Resources (in situ)

Uranium 2020: Resources, Production and Demand Table 1.2b. Identified resources (in situ)** (as of 1 January 2019, tonnes U, rounded to nearest 100 tonnes) * Secretariat estimate. (a) Not reported in 2019 responses, data from previous Red Book. (b) Assessment partially made within the last five years. (c) Assessment not made within the last five years. (d) Recoverable resources were adjusted by the Secretariat to estimate in situ resources using recovery factors provided by countries or estimated by the Secretariat according to the expected production method (Appendix 3). (e) Cost data not provided, therefore resources are reported in the <USD 260/kgU category. (f) Recovery factor change from previous report. (g) Totals related to cost ranges <USD 40/kgU and <USD 80/kgU should be regarded with some caution since certain countries do not report low-cost resource estimates, mainly for reasons of confidentiality, whereas other countries that have never, or not recently hosted uranium mining, may be underestimating mining costs.
