Method overview

Remote sensing, geology, geochemistry, and fieldwork combined in a traceable cycle of mineral investigation.

An evidence cycle

Each stage reduces uncertainty and informs the next. The method organizes available public data, geological observations, and field results without confusing an exploration hypothesis with a mineral reserve.

  • Expand territorial understanding across scales.
  • Prioritize areas through converging evidence.
  • Validate hypotheses and recalibrate the next cycle.

Four movements

The method is not a rigid sequence. It is a cycle in which new evidence can revise priorities and return questions to earlier stages.

#What it shows
01ObserveMultispectral imagery, terrain models, and mapping help recognize patterns, structures, and regional contexts.
02IntegrateGeological, geochemical, mineralogical, and territorial data are normalized and compared as complementary evidence.
03PrioritizeFavorability is examined through convergence between independent signals, explicit criteria, and testable hypotheses.
04ValidateGeoreferenced observation, sampling, and laboratory analysis confront the hypothesis with the ground and feed the next iteration.

Criteria at every stage

Technology expands analytical capacity. The method's quality depends on how evidence is interpreted, documented, and tested.

  • Evidence before conclusion: No isolated signal determines a decision. Weight comes from convergence between independent sources.
  • A target is not a reserve: The method keeps favorable areas, investigation targets, mineral resources, and reserves clearly distinct.
  • Fieldwork closes the cycle: Digital hypotheses gain value when they can be confronted through observation, sampling, and analysis.
  • Traceable decisions: Criteria, sources, and revisions remain visible so each priority can be understood and reassessed.
