Fundamentals of Mineral Resource Estimation

East Meeting Level / Registration Required
Speaker(s): Valerie Wilson Sean Horan David Ross Jason Cox Luke Evans

Presented by: Roscoe Postle Associates (RPA)

Full 1.5 day Course Cost: Regular – $693 (includes GST); Students $199.50 (limited spaces)
Course Time – Saturday (8:30 AM – 4:30 PM); Sunday (8:30 AM – 12:00 PM)

Course Description:

The course starts where the exploration geologist often stops, at the resource database, and proceeds to domaining, block modelling, verification, and resource reporting. The course focuses on the practical aspects of resource estimation, including a discussion of geological versus resource domain modelling, exploratory data analysis and outlier restriction tools, trend analysis, and the incorporation of conceptual mining inputs (minimum thickness, cut-off grade, etc.). RPA will also present an overview of common estimation tools, guidance for selecting interpolation criteria (search ellipse size and orientation, min/max composites), cut-off grade and NSR calculations, classification considerations, model verification tools, and Mineral Resource reporting. The fundamentals and importance of each step, including common risks and mistakes will be discussed. Each learning outcome will be reinforced through practical exercises, and participation in a live peer review session.

Top Take-Aways:

  • Understand the steps involved to estimate Mineral Resources
  • Build their own basic tool kit to estimate Mineral Resources
  • Be able to identify common risks and gaps in the estimation process
  • Apply practical considerations of resource estimation to field data collection and collation.

Who should attend:

This course is intended for exploration and mine geologists, as well as other groups of practitioners primarily responsible for the discovery, definition, and production of mineral discoveries. Attendees should be familiar with exploration drilling methods and results and the general geology of some mineral deposits.
