The Successful Application of Modern Exploration Techniques oo Previously Explored Areas in the Athabasca Basin, Canada

Several project areas within the Athabasca Basin of northern Saskatchewan, Canada, that were explored in the 1970s and 1980s have had recent discoveries due to the application of modern exploration techniques and the evolution in the understanding of unconformity uranium deposit models. The Griffith showings of the Maurice Bay area and the Patterson Lake deposit on the west side of the basin, and the Roughrider and Phoenix deposits on the east side of the basin are all relatively recent discoveries in areas that were explored in the past. This paper describes the exploration methods that were used to locate "new" mineralization within previously explored areas. (author)
