“I’m very excited to be joining Northwestern’s Board,” said Mr. Subotic. “This is a dynamic time for the company and I am looking forward to providing support as Northwestern continues to advance its high-potential uranium properties in Niger and Canada.”

Mr Subotic has been granted 200,000 stock options, each such option entitling the holder thereof to acquire one common share of the Company at an exercise price of C$1.03. The options will vest in stages over five years and expire on July 4, 2012.”
