FOR HISTORICAL DATASETS

Give existing magnetic data another look

Older surveys can still contain useful information. A fresh, documented review can test prior interpretations against additional data and current exploration questions.

EVIDENCE 01

Start with a data inventory

We assess original observations, grids, acquisition reports, processing history, coordinate reference and coverage. The quality and completeness of the source package determine which new products or comparisons can be defended.

EVIDENCE 02

Revisit old conclusions

Compare magnetic features with geology, gravity, drilling and known occurrences. Where appropriate, the team can look for overlooked subfeatures, changed geological context and alternative explanations for earlier targets.

EVIDENCE 03

Choose the depth of review

A rapid screening can organize questions for a technical meeting. A deeper assignment can document processing, evidence by target, uncertainty and a proposed field or survey program. Any formal inversion requires verified observations and appropriate physics, rather than a map image alone.

What the team can use

  • Extract more value from data already acquired
  • Validate, refine or challenge earlier target hypotheses
  • Identify the next dataset most likely to resolve uncertainty
