Exploration Target Ranking
Available on requestRank ground across a district or belt by how closely its surface alteration matches known mineral systems. Every part of the area receives a score, producing a shortlist of targets before a field season is committed. Where white mica alteration is continuous, a second layer tracks its compositional shift from the centre of a porphyry system out to its fringe. Every score traces back to the alteration map it was built from.
Built for exploration managers ranking ground across a belt, geologists placing the first mapping and sampling, and investors comparing the surface case for several projects.
Core Capabilities
Ranked Shortlist
Every part of a district is scored, so crews start on the ground closest to a known mineral system.
Directional Vectoring
The white mica layer indicates which way the hydrothermal centre lies.
Documented Validation
The cross-validation scheme travels with the score into your GIS.
Inputs and Deliverables
Inputs Required
- District or belt boundary (GeoJSON, zipped shapefile, or KML).
- Target deposit style (for example, porphyry copper-gold).
Deliverables
- Cloud-Optimized GeoTIFF district score surface, with likelihood contours as GeoJSON.
- White mica vector layer pointing toward the hydrothermal centre, where the alteration is continuous.
- Alteration map underlying the scores.
- Provenance record specifying the model version, input scenes, and validation scheme.
Methodology and Sources

Limits of Detection
Scores rank surface alteration against known mineral systems. Grade, concentration, and reserves are not measured.
The score is cross-validated with whole regions withheld from fitting, and the validation scheme is documented on the layer.
Vectoring is applied where white mica alteration is continuous and the signal is strong, and the layer records where it was drawn. Hydrothermal systems with exposed alteration, such as porphyry copper-gold and epithermal ground, provide the strongest basis for scoring.
Workflow
Submit Boundaries
Provide the district or belt geometry and the target deposit style.
Alteration Mapping
We map alteration across the district as the basis for the score.
Scoring and Vectoring
The district score is computed across the area and the white mica vector is drawn where alteration is continuous.
Delivery
You receive the score surface, contours, vector layer, and alteration map.
Use Cases
Exploration Geologists
Rank ground across a belt and decide where the first mapping and sampling go.
Mine Operators
Score the district around a running mine to decide where near-mine exploration starts.
Investors and Lenders
Compare the surface case for several projects on one method before a site visit.
