Technology
Hydrometallurgy, engineered for the north.
Northern tailings vary widely in mineralogy, grade, and geotechnical condition — and they sit in a cold, water-sensitive, permafrost-adjacent environment. Our process is designed to be characterized quickly, deployed modularly, and returned to site with a smaller, more stable footprint than what was there before.
The circuit.
- Characterization
- Bulk sampling, mineralogy, and metallurgical test work to establish the recovery envelope for each tailings body.
- Leach
- Selective chemistry matched to the ore, prioritizing silver while capturing gold and base-metal by-products where economic.
- Recovery
- Solution processing to produce a saleable silver product and precipitate residual metals.
- Residue management
- De-watered, chemically stabilized residues returned to storage with reduced volume and improved water chemistry.
Designed for the north
Cold-tolerant
Circuit chemistry and heat management engineered for sub-arctic operation, not retrofitted from temperate designs.
Water-first
Closed-loop water handling that improves, not degrades, downstream water chemistry.
Permafrost-aware
Residue placement and site works planned around thermal regime, ground stability, and long-term monitoring.
Technical claims to be substantiated by third-party test work and disclosed under applicable reporting standards.
