Technical approach

As reported
AI Mineral Exploration

Machine learning on geological data

AI trained on geological, satellite, and academic data plus proprietary field measurements. Models predict high-grade deposits.

Efficacy of Information

Reducing exploration uncertainty

Proprietary framework determines which data to collect at each step to maximize certainty and minimize drilling costs.

Deep Deposits

Finding ore far underground

AI locates high-grade ore at ~1,700 m depth, where conventional surveys miss deposits.
