I just checked SEDAR tonight and found a very comprehensive Annual Report filed by SNO on January 11, 2008. It describes their full history, current projects, legal agreements, geological details, results of activity, capital structure, etc. etc. It is a long read - a 49 page pdf file, but worthwhile reading if you are in search of "gems"!
