Pit Models

Pit models in Strategy are block models that meet the following requirements:

• All blocks have the same dimensions (there are no subblocks).
• All blocks must be within the ultimate pit limit.
• All blocks have to be mined.
• All blocks have a stage variable encoded with one or more stages, phases, or shells, which are encoded in the pit.
• All blocks have a variable that represents the total tonnage of that block.
• All blocks have a variable that represents the ore tonnes of that block.
• All blocks have at least one grade variable that gives the amount of product or metal in each ore tonne.
• All blocks have a lithology variable with one or more lithologies encoded in the model. This can be used to determine which processes a block’s ore can flow to.

For more information on creating these models, see Block Models.
