Hi Boot
You make reference to Agnico Eagle's Goldex deposit. You might be interested to check out AE's 2011 exploration plan for Goldex at http://www.agnico-eagle.com/Theme/Agnico2/files/Presentations/Exploration%20Show%20and%20Tell%20Presentation.pdf see pages 11 and 12. There they are already mining down to the 800M level and have an exploration drilling plan for 58,200 meters this year to go after the D zone which extends even deeper. The Goldex Extenstion zone has grades just marginally over 2g and the same is expected in the D zone.
cheers
