Vulcan 9 Modelling Tools

Maptek™ resource geologist Anthony Bottrill combines new implicit modelling tools in Vulcan™ with existing change of support analysis to lift the lid on evaluating deposits. This is critical when including mine planning and financial modelling concepts into discussions.

• database validation;
• advanced statistics; and
• load drillholes as discs for displaying grade and geology.

• a potential mineralised tonnage; and
• a potential tonnage and grade above an economic cutoff.

Adjusting the parameters in implicit modelling allows the resource geologist to determine end-member ranges for the size of the deposit based on the data available.

Two real world projects identified situations where:
• infill drilling would cost more than the potential incremental value of additional metal in the ground; and
• a large low grade project which contained significant high grade ore shoot potential had significant upside as a high grade target.
