Geostatistical Methods For The Estimation Of Minable Reserves In Stratiform Uranium Deposits (9e200d18-6131-4dd7-b224-0fbc6b7292bf)

The ore reserve modeling of stratiform uranium deposits to be mined by selective underground mining methods must be done with consideration of the erratic nature of the ore forming processes that produced the mineralization. Estimation methods that model the uranium grade as a smooth transition between high grade and low grade drillhole intercepts tend to greatly overestimate the ore tonnage. Care must be taken to first establish realistic ore pod geometries and then estimate the grade of the reserve units within the pods.
