Abstract

In this study, a 3D geological model of the eastern sub-Athabasca basement of northern Saskatchewan (i.e. the eastern and western Wollaston domains, the Wollaston-Mudjatik Transition Zone (WMTZ), and the Mudjatik Domain) was developed using the SKUA-GOCAD environment and the GOCAD{\textregistered} Mining Suite. The model is constrained by topographic, geophysical potential field, outcrop, drill hole, petrophysical, and petrological data, along with high-resolution regional seismic lines, in order to better understand the uranium mineral system(s) operating pre-, syn-, and post-Athabasca deposition on a regional to mine scale. This knowledge is utilized to identify key metallogenic parameters and exploration vectoring indices for pre-Athabasca magmatic and metamorphic/metasomatic uranium deposits, and most importantly for basement-hosted unconformity-type (U/C-type) uranium deposits. The ultimate goal is to delineate new exploration targets within the eastern part of the basin.
