"AREVA continues to deliver spectacular drilling results from Shea Creek, which has led to their plans to sink an exploration shaft and development of exploration drifts into the Kianna and Anne deposits," said Stephen Sorensen, President and CEO of UEX. "To date, UEX has far exceeded its expenditure obligations under the Agreement, and is very pleased with AREVA's operations at the Projects, and in particular, their exploration success at the Kianna Deposit."
