Core Logging

Core logging is the systematic description and measurement of drill core to capture lithology, structures, alteration, and mineralization. It matters because accurate logs inform resource models, geotechnical decisions, and environmental compliance, improving safety and reducing costly drilling or planning errors.

A professional with strong core logging can:

Measure And Record Core Recovery, RQD, And Geotechnical Parameters To Support Stability And Ground-control Assessments.

Describe Lithology, Textures, Structures, And Alteration Consistently Using Standard Logging Codes And Terminology.

Mark Sample Intervals, Document Mineralization And Contacts, And Prepare Cores For Assaying With Full Chain-of-custody Records.

Enter Logs, Photos, And QA/QC Checks Into Geological Databases And Reconcile Discrepancies With Field And Lab Data.

Core Logging

Why Core Logging Matters

Feed Accurate Lithology And Alteration Data Into Resource Models And Grade Estimates.

Support Safe Pit And Underground Designs Using Recovery, RQD, And Geotechnical Logs.

Ensure Assay Integrity By Marking Intervals And Maintaining Chain-of-custody Records.

Avoid Costly Drilling Mistakes By Reconciling Field Logs With Lab And Database QA/QC.
