In-situ core logging

In-situ analysis using multispectral core logging

Germany

Summary

The in-situ core logging devices save time and allow direct generation of results on site.

Description

Drill cores need to be analysed not only visually but also mineralogically and geochemically. This has traditionally been a laborious and time-consuming exercise since samples had to be taken, processed and analysed, typically at a laboratory a significant distance away. New devices introduce in-situ logging and analyses of the drill core at or close to the drill site.

Impact on the mining value chain

  • EXPLORATION (incl. permitting)
  • EXTRACTION (incl. Permitting)
  • mineral and metallurgical PROCESSING (incl. Permitting)
  • DATA and knowledge base

Exploration

  • safe and fast remote exploration
  • reduced environmental impact

Extraction

  • reduced grade deposit mining

Processing

  • reduced grade deposit mining

Linked policies

Transferability

Good example of interaction between development of new analytical techniques and application in on-site settings.

Innovation drivers and barriers
Drivers
Economic
Faster results with better quality analysis
Other
The mining industry was asking for better ways on how to analyse drill core samples.
Barriers
Economic
Cost and time consuming (for field geologist) - sometimes reluctance to approach innovation

Good practice areas

Economic sustainability
Time
Resource security
Analytic precision, avoidance of transport costs and emissions
Good governance
Reporting of results in a transparent manner

Organisations involved

Geological Surveys (e.g. German BGR, Hannover)
Private industry (e.g. with products such as TerraSpec, PeMa and early users such as Anglo American)
