OVR grades
19.0 metres at 8.4% zinc from 33.0 metres, within
46.8 metres at 4.6% zinc from 5.2 metres in DY10-024.
8.0 metres at 3.8% zinc from 87.0 metres in DY10-024, and
8.0 metres at 19.4% zinc from 80.0 metres in DY10-025.

Looks to me as mii grades are far better then ovr, but the daytraders seem to be all on ovr
