Ann: New 49,000 Siemens EM Conductor at Mt Alexander, page-264

Whatever the reason, at normal DD drill rates ( 30+ m per day with single shift) given 20 days now elapsed from start we should well and truly be past that EM plate. So, either... the drill has deviated and the plate was missed ( in which case may need to run a wedge hole of the mother hole), or the drill has got stuck ( but I think we would have been advised if this happened) or the drill rate is painfully slow due the fault(s). Or we got nothing, but that would seem odd given the strength of the conductor. Still wish we had done a wedge hole off MAD 184 to start with, minimal cost, a few days of wedge drilling would have reached the EM plate for a preliminary "look-see"
