REE Prospectivity

A private Mining Intelligence screening model that identifies regions where the available geological evidence is comparatively more favourable for rare-earth investigation — a carbonatite- and alkaline-related fertility prior, published as a sealed research campaign. Prospectivity is not probability, a target zone is not a deposit, and a score is not a chance of discovery.

Which part of GeaSpirit produced this

This page publishes the aggregate result of a campaign run by GeaSpirit's Mineral Prospectivity engine — a weights-of-evidence model that learns, from known mineral occurrences, how strongly each geological control predicts a deposit, and reports each layer's learned contrast so the reasoning can be inspected rather than trusted. The REE campaign is one model inside that engine: a carbonatite- and alkaline-related fertility prior.

The ranking itself is computed, not chosen. Layers are loaded, variables derived, the model applied, regions ordered, and targets and controls selected by rule — then the whole set is hashed and time-stamped in one operation, so the same campaign can be recomputed and checked. What a person decides is which sources are scientifically admissible, how the model is defined, and whether a campaign is published at all. Nobody picks individual targets by hand; that would destroy the only thing a sealed campaign is for.

The campaign is unsealed and public. Exact coordinates, individual ranks and scores, and the evidence classes behind each of the 100 elements are published unaltered — recomputing the Merkle root from them reproduces the value that was committed and independently time-stamped before publication. No counter-evidence is published because v0.4 never recorded any, and what is still missing to advance an element is not an argument against it. Disclosure does not resolve the campaign: all 100 elements remain unresolved, and the published file carries the whole verification trail.

Regional prospectivity — not deposit detection

This is a relative regional rank, not a reserve, grade, tonnage or probability of a deposit. It does not claim that rare earths are present at any place. It only points to regions that deserve scientific attention.

Sealed campaign v0.4

The v0.4 prospective campaign was sealed before publication and is now disclosed in full. Its contents were committed and time-stamped first, so the ranking cannot have been altered afterwards. It remains unresolved.

Campaign at a glance

All 100 elements are published with their coordinates, scores and ranks. The Merkle leaves are not shipped — anyone can recompute them, and the root, from the published entries and the published canonicalisation rule.

Continental distribution (aggregate)

These 100 committed elements are 50 prospective targets + 50 controls — not 100 deposits. No coordinates or individual scores are shown.

Validation status

Internal validation supports a measurable regional ranking signal. Independent external evidence is still required.

What this does not prove

Presence, grade, depth, tonnage, resources or reserves of rare earths. The score is a relative regional rank, not a probability of a deposit. The campaign is unresolved.
