Remove Unregistered Holes

Use the option DH-Data > Remove Unregistered Holes (DHCLEAN GX) to delete holes not registered in the collar table.

Application Notes

To delete holes and tables of holes which do not appear in the collar table, use the DHCLEAN GX. This may be necessary when rows in the collar table are deleted by the user directly, and so tables for the deleted holes may remain in the survey or assay databases. To delete holes that are registered in the collar database, use the DH-Data > Delete Drillhole menu item.
