FOR HISTORICAL DATASETS
Older surveys can still contain useful information. A fresh, documented review can test prior interpretations against additional data and current exploration questions.
EVIDENCE 01
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
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
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.
The figures above are preliminary public-data examples, not mineral-resource estimates or drilling instructions.
