Abstract

Formerly, uranium exploration at the Husab Uranium Project was based on sample chemical uranium assays with little uranium equivalent data (eU) obtained from γ probing. The high cost of performing chemical assays has a significant impact on the overall cost of uranium exploration. Between 2015 and 2016, the Resource Upgrade Project Zone 2 was undertaken at the Husab Project, which identified the reliability and feasibility of γ probing through comparison of chemical uranium assays with uranium equivalent grades. This project analyzed the sources of errors and proposed a method to correct them. Uranium equivalent data from gamma probing can be used to replace the chemical assays to reduce the cost and time, therefore increasing the efficiency for uranium exploration at the Husab Uranium Project.

Key words
