Uranium Identified Resources

Uranium 2020: Resources, Production and Demand Table 1.2a. Identified resources (recoverable)(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) In situ resources were adjusted by the Secretariat to estimate recoverable resources using recovery  factors provided  by  countries or  estimated  by  the  Secretariat. (e) Cost data not provided, therefore  resources are  reported  in the <USD 260/kgU category. (f) Updated to report recoverable resources.(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 confidentiality concerns, whereas othercountries that have never, or not recently hosted uranium mining, may be underestimating mining costs.

铀资源2020：资源、产量与需求表1.2a. 已识别资源（可回收资源）（截至2019年1月1日，以吨铀计，四舍五入至最接近的100吨）。* 秘书处估计。（a）2019年未报告的数据，来源于前版《红皮书》。（b）过去五年内部分完成评估。（c）过去五年内未完成评估。（d）现场资源已由秘书处根据各国提供的或秘书处估算的回收系数进行调整，以估算可回收资源。（e）未提供成本数据，因此资源报告在“<USD 260/kgU”类别中。（f）更新以报告可回收资源。（g）与成本范围<USD 40/kgU和<USD 80/kgU相关的总计应谨慎对待，因为某些国家出于保密考虑，未报告低成本资源估计，而其他从未或近期未举办铀矿开采的国家可能会低估采矿成本。
