The Grey Island Project is located 70km to the west of the Key Lake Mine owned by Cameco and Orano and 60km to the east of Cameco's Centennial uranium deposit. The survey was completed by Expert Geophysics Surveys Inc and provided an up-to-date dataset characterizing the property's subsurface features and establishing an initial framework for future geological evaluation and follow-up exploration. The Grey Island has seen very limited historical exploration; it is located near the Cable Bay Shear Zone (see Figure 1), a regional structural feature that is interpreted to be a prospective conductive corridor with known mineralized occurrences such as drill hole ND0801 drilled by Nuinsco, intersected 707ppm Uranium in a sandstone sample at the unconformity, just 12km to the west of the Grey Island Project. To the east, CanAlaska's Cree East property has seen assays up to 0.015% U3O8 approximately 10km from Grey Island. Only one documented drill hole FLM-08-05 (see Figure 1) has been completed on the property itself. This hole reported bleaching and alteration in the sandstone, along with pyritic and graphitic alteration in the basement rocks - the early geological signatures we look for within conductive packages as indicators of possible uranium bearing systems. Erik Sehn, VP Exploration, commented:\"Grey Island represents our largest, and most underexplored land package in the southern Athabasca Basin. With only a single historic drill hole and outdated geophysical data available, we consider the Mobile MT survey as an important first step to assess the property for conductive trends. The results of this survey display large, linear resistivity low anomalies and merit further target generation, initially with detailed ground geophysics and eventually drilling.\"About Grey Island:F4 Uranium's...
