3-D Model 1
This model shows the mineralization as defined by drill hole intercepts to date (no interpretation nor interpolation used). The flat surface located on the top section of the model represents the unconformity; everything above this point (no colour) represents Athabasca sandstone. Discovery Drill Hole (MWNE-08-12) is shown for reference.
