Key points
- The Norwegian shelf authority estimates 40 million tons of copper in seafloor massive sulfides, roughly twice annual global copper production.
- The mining system uses a semi-submersible platform deployable to 3,000-meter depths in 10 hours, developed with partners including Oil States and Soil Machine Dynamics.
- A blendability study with the Finnish Geological Survey confirmed that seafloor massive sulfide ore can be processed in existing terrestrial mining infrastructure with high recovery rates.
- Green Minerals achieved an 80% reduction in operating costs from 2024 levels in the first half and expects licensing awards in the second quarter of 2026.
