Follow these steps when good dirt doesn't get reclaimed from stockpile.

If the schedule has these issues, resolve them first:

Check 1: Schedule > Calendar > Stockpiles > Actual Capacity

Check 2: Setup > Destination Logic

Check 3: (Truck Constrained) Schedule > Calendar > Stockpiles

Check 4: (Truck Constrained) Schedule > Trace > Trace Report

Stockpiles/ROM1_1 is blocked by multiple Calendar constraints.

Check 5: Setup > Opening Inventories

Make sure that tonnes and grades are populated in all Mining and Processing fields. Missing entries are evaluated as zeroes, which may affect the optimisation.

Check for missing grades and tonnes in Opening Inventories.

Check 6: Schedule > Calendar > Stockpiles

Stockpiles may be forced to reclaim material if the closing capacity is less than the opening inventory. This can cause otherwise rubbish material to take precedence over preferred stockpiles.

Check for forced reclaim due to closing capacity limits.

Check 7: Schedule > Calendar > Constraints

Check for constraints blocking specific stockpiles or materials from feeding.

Check 8: Schedule > Calendar > Product Specifications

Compare the target grades to the inventory in Reporting > Stockpile Inventories. Are they achievable?
Check the cash flows for penalties on reclaiming certain stockpiles or materials. Is this stockpile affected?

Check 9: Schedule > Calendar > Forced Optimisation Failure
Create a forced optimisation failure and read the failure message.

Go to Schedule > Calendar > Stockpiles and reduce the capacity of the desired stockpile (this forces it to feed).
Run the schedule.
Read the failure message.

If there is no failure message, return to Check 8.
