Denison Mines updates uranium exploration activities. A program of both infill and exploration drilling is well underway with two drills at Wheeler River. Eighteen of 28 planned drill holes have been completed. One of the first exploration drill holes of the program, drill hole WR-489, located approximately 2.1 kilometres northeast of the Phoenix deposits intersected uranium mineralization in faulted graphitic pelitic gneiss immediately below the sub-Athabasca unconformity at a vertical depth of 380 meters below surface. A 2,370 metre drilling program has been completed on the Hatchet Lake property in the northern part of the eastern Athabasca Basin. Hatchet Lake is 50% owned and operated by Denison and 50% owned by Anthem Resources Inc. A total of 13 drill holes, including one re-start, were completed during the program - two more than originally planned due to the intersection of uranium mineralization at the unconformity in two drill holes on the Crooked-Richardson Lakes trend.
