Minestarters Atlas analysis
Summary
Perpetual Resources is planning a resource definition drilling campaign at its Raptor project in Brazil to support a potential maiden resource estimate. The project has shown high TREO grades and encouraging magnet rare earth recoveries in previous shallow drilling.
Reasoning: The company is transitioning from early exploration to resource definition, supported by strong historical grades and metallurgical results.
Positive factors
- Planned resource definition drilling to inform maiden resource estimate
- High historical grades (up to 5591ppm TREO)
- Encouraging metallurgical recoveries (peak 93.8%)
- Strategic location in Caldeira district near Lynas/Meteoric interest
Negative factors
- Historical drilling used auger rigs with limited penetration depth
- Full extent of mineralisation remains untested
Facts used in scoring: 5
Classification and evidence
Infill Drillingneutral
Confirmatory drilling to raise resource confidence, not new discovery.
Why it applies: Company is planning infill and extension drilling to test grade distribution and continuity.

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
