Tailings & Residual-Value Opportunities
Tailings and dormant sites can hold residual value. GeaSpirit applies the same explainable, open-data methodology to screen dormant assets for opportunity signals — without claiming any guaranteed recovery or sale.
How GeaSpirit helps
- Prioritize tailings and dormant sites by opportunity signal.
- Use the honest certainty band to flag low-validation targets.
- Commission a Tailings / Abandoned Mine Review report.
