First presented: 
AusIMM Uranium Conference, June 2013

GoviEx is a private exploration and development company with 10 tenements totaling approximately 5,000 km² of exploration ground in Niger, the world’s sixth largest uranium producer. As of August 2012, GoviEx’s properties contained more than 121 million pounds of NI 43-101-compliant uranium resources. GoviEx’s technical team has completed more than 550,000 m of drilling and radiometric logging on its tenements.

This presentation is focused on some of the exploration and development results of the 2010-Q1 2013 exploration drilling program which led to the discovery of new uranium mineralisation in the Tim Mersoi Basin. The mineralisation is hosted either within the Guezouman (Mad1 South, Miriam) or within the Madaouela formation, which represents a transitional term between the reduced sediments of the Carboniferous period, and the continental red beds of the Permian era.
