International Enexco Ltd.: Winter Geophysical Survey Planned at Mann Lake, Saskatchewan

VANCOUVER, BRITISH COLUMBIA–(Marketwire – March 1, 2012) – International Enexco Ltd. (TSX VENTURE:IEC)(OTCQX:IEXCF)(FRANKFURT:IE6) (the “Company” or “Enexco”) is pleased to announce that preparations for a geophysical survey over the Mann Lake Uranium Project, situated in Saskatchewan’s prolific Athabasca basin are underway.

A Stepwise Moving Loop Time Domain EM survey at a cost of $155,400 will be directed by our joint venture partner and project operator, Cameco Corporation (“Cameco”) to better establish and define conductor traces and provide future drill targets. The Survey will be conducted by Quantec Geosciences and is scheduled to begin by the end of February.

Enexco is a 30% partner in a joint-venture with Cameco (52.5%) and AREVA (17.5%) to explore the Mann Lake Uranium Project in the Athabasca Basin in Saskatchewan.

The Mann Lake Uranium Project lies 20 km from Cameco’s McArthur River Mine and is 15 km from Cameco’s Millennium deposit. High-grade uranium was discovered at Mann Lake during a 2007 drill program. The two highest grade intervals averaged 7.12% U308 over 0.25 m and 5.53% U308 over 0.4 m at depths of just over 500 m.
