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.","length":882,"tagName":"p"},{"type":"text","content":"Erik Sehn, VP Exploration, commented:","length":37,"tagName":"p"},{"type":"text","content":""Grey Island represents our largest, and most underexplored land package in the southern Athabasca Basin.
