“We will always be wrong. We estimate, we do not calculate. But rather be ‘roughly right’ than ‘precisely wrong’!”

Mike O’Brien developed this June 2019 presentation to give junior Geologists who are at the start of their careers the ins, outs, upsides and pitfalls of Mineral Resource Estimation. The presentation, based on his more than 25 years of experience, deals with:

  • Context
  • Purpose
  • 3D Geology Models
  • Domains for Estimation
  • Grade Capping
  • Compositing
  • Spatial Analysis
  • Search Strategy
  • Block Size
    Estimation Methods
  • Validating Estimates
  • Resource Categorization
  • Words of Wisdom Warning
