Qualified comments: (Applies to: discovery and development) Early uranium exploration during 1969-'85 was regional in nature, comprising airborne magnetic and EM surveys, regional till, vegetation, lake and stream geochemical surveys, and geological mapping. Bulk of the work was carried out by Marine Oil Company from 1978 to 1981. In 1990, Cogema Resource Inc., Areva Reources Canada Ltd. as of 2006, initiated the Shea Creek Project that included deep-penetrating Geotem magnetic-EM survey. Follow-up ground magnetic, gravimetric and moving loop EM surveys identified a graphitic conductor, named the Saskatoon Lake Conductor trending 325°. By mid-nineties additional work extended the conductor's defined length to 25 km. Drilling began in 1992, and hole SHE-2 intersected favourable alteration and 0.6 % U over 0.7 m in a graphitic shear zone at a depth of at depth of 700 m. Drilling to the north along the conductor led to the discovery of Anne zone nearby in 1994, and of Colette zone in 1996 about 2.5 km to the northwest. The first indications of the Kianna zone, located about 600 m NNW of Anne zone, were obtained in hole SHE-63B drilled in 1997. It was followed by further drilling in 2000. In 2004 the Areva Resources Canada Inc. signed a joint venture agreement with UEX Corporation to continue exploration along the Shea Creek trend (Saskatoon Lake conductor).In 2005, the economic significance of the Kianna zone was realized when hole SHE-114-5 intersected 27.4 % U over 8.8 m.
