RR Single Destinations

The Single Destinations mode forces a dig block to contain a single parcel type, with the average grade of all contained block model materials. This can be used to represent dilution, reduce selectivity in scheduling, and to create grade control blockouts.

Dig blocks can be automatically generated using the ‘Automated Dig Lines’ tool in the Designer tab.

Implementation Notes

By default, Single Destinations mode does not know the grade bands of each material type.

This means that a polygon with 95% high grade and 5% waste may still be binned as high grade, even if the average metal content is lower than the high grade cutoff.

In order to properly account for grade bands in materials, a custom cash flow must be implemented. Implementations are typically done by Alastri support staff and maintained by the client-side project owner.
