GEOLOGICAL MODELLING

Geological Modelling is at the core of our business. Impala staff have built Geology and Resource models for approaching 100 deposits worldwide, in a wide range of commodity and mineralisation styles. The majority of our commissions fall into the following categories:

• Combined Geology & Resource Models for use in compliant Mineral Resource estimates

  1. this typically involves building a geological model

  2. identifying the key controls on mineralisation (where required, Impala has collaborated successfully with a number of world class structural geologists to help identify these controls and build them into the modelling process)

  3. building resource domains that reflect the in-situ mineralisation

  4. statistically and visually validating these domains

  5. providing recommendations for appropriate interpolation parameters and classification to the CP undertaking the Mineral Resource estimate.

• Grade control models for short term mine planning

  • most frequently this involves designing a modelling workflow that can be updated by the client going forward, rather than a single model

• Waste Models for Mine Planning

• Geotechnical domaining based on RQD or alteration data

• Acid generating or Deleterious element models for waste rock disposal or processing planning.

Impala are specialists in both explicit and implicit model techniques and work with the latest Leapfrog Geo® 3Dmodelling software.
