The original MSV discovery hole, SJ-18-21, stopped at a TD of 889 m in marble/skarn alteration. They are now drilling below that depth and report they are encountering marble. It should be fast drilling in that rock and they'll know if they've encountered massive sulphides as soon as the core reaches surface. Sitting on that rig and logging the core would be one very exciting place right now. If they get a strike we'll hear any day now.
