2. Create Tables step
Tables should be created for each class of blocks: pits, dumps, and (optionally) backfills. The number of levels in each table should match the level hierarchy of the inventory files, so they can be mapped one-to-one in the Map Fields step.
Overview
A table marked Holds Dumps has no reserves information and cannot be mined. If an area must be dumped and reclaimed (such as a land bridge), then the blocks must be imported twice (once as dumps, once as reserves).
