Resource estimation is both an art and a science. It’s the foundation of any mining project—and getting it wrong can be catastrophic. So how do the pros do it?
Key Steps in Resource and Reserve Estimation
- Sampling: Drill cores, trenching, and chip samples collected with precision.
- Geological Modeling: 3D modeling of the orebody using software like Surpac or Datamine.
- Grade Estimation: Techniques like kriging, inverse distance weighting, or nearest neighbor.
- Classification: Into Inferred, Indicated, or Measured (based on confidence levels).
- Economic Viability: Only then is it declared a “reserve.”
Regulatory Standards
Reporting codes such as NI 43-101 (Canada), JORC (Australia), and SAMREC (South Africa) ensure global transparency.
Final Word
A credible estimate can attract investors, guide feasibility studies, and lay the groundwork for mine planning. At VUCAMine Consult, we combine software, geology, and compliance to deliver results that clients can trust.
