Slide 1: 2010 Technical Report for the Hodgson Project, Saskatchewan
2010 TECHNICAL REPORT FOR THE HODGSON PROJECT, SASKATCHEWAN FOR CANALASKA URANIUM LTD . Prepared by: Peter Daubeny, M.Sc., P.Geo September 2010 i SUMMARY The Hodgson project is located in the east central part of the Athabasca basin and is comprised of six mineral claims totalling 249.4 km 2 . The c

1. Hodgson Project road access and area mineral deposits ACCESS, CLIMATE, TOPOGRAPHY AND INFRASTRUCTURE The Hodgson property is located approximately 700 km northeast of Saskatoon and 70 km south south-east of Points North Landing. Points North Landing is accessed by Saskatchewan Highway 905 from La

Geology of the Athabasca Basin 5.2 Property Geology Geologic Atlas of Saskatchewan interpreted geology indicates that Dunlop Member (MFd) sandstone of the Manitou Falls Formation underlies the Hodgson project property. The Manitou Falls Formation has been subdivided into four members by Ramaekers
Slide 7: Unconformity-associated uranium deposit models
6. Unconformity-associated uranium deposit models Basement hosted deposits typically have narrow, inverted alteration halos along the sides of the basement structure. Halos can grade from illite ± sudoite directly adjacent to mineralization through sudoite ± illite, to Fe-Mg chlorite ± sudoite on th

Slide 13: Sandstone, unconformity and basement hosted conductors
12. Sandstone, unconformity and basement hosted conductors. Irving (2006) examined the “processing outcomes” from the VTEM survey and selected three target zones that now lie in or near the current Hodgson claim block. All of these target zones broadly correlate with magnetic lows indicating that Ap
