Field validation

We take prioritized hypotheses into the field to measure, sample, review, and learn.

Georeferenced observation, sampling, and laboratory analysis confront the hypothesis with the ground and feed the next iteration.

Prioritized hypotheses move into the field for georeferenced observation, sampling, and laboratory review. Results inform the next investigation cycle.

Fieldwork closes the cycle

Digital hypotheses gain value when they can be confronted through observation, sampling, and analysis.

Participation with clear criteria

Contributing does not mean automatic approval, a mineral discovery, payment, or mineral rights. Technical quality and responsible land practices come first.

  • Traceability: Every input needs a clear origin, context, and understandable limits of use.
  • Consent: Private data, documents, and land access only proceed with proper authorization.
  • Technical decision: Review may end the journey when evidence or method fit is insufficient.
  • No early promise: Rewards can only exist after public rules, eligibility, and availability are confirmed.
