Geophysical Characterization and MRV Strategy for In-Situ CO2 Mineralization at the CO2 Lock Sam Site, Canada

CO2 Lock Corp. is developing a novel climate solution through in-situ mineralization of carbon dioxide in brucite-rich ultramafic formations. Its flagship site, Sam, located in British Columbia (Canada), leverages the high reactivity of brucite to permanently convert injected CO2 into stable carbonate minerals. To inform site development, a high-resolution Towed Transient Electromagnetic (tTEM) survey was conducted across the property. This rapid, ground-based resistivity method produced dense geoelectrical imaging of the shallow subsurface, helping to identify fracture networks and competent lithologies. These insights supported the selection of drilling targets and informed preliminary injection zone planning.

The upcoming pilot will involve injecting CO2-saturated water into identified fracture zones to test mineralization efficiency. A comprehensive Monitoring, Reporting, and Verification (MRV) framework will be deployed to ensure scientific rigor and traceability. It integrates geophysical, geochemical, and hydrogeological methods to monitor fluid movement, track mineralization progress, and validate permanent CO2 storage.

Together, these tools serve dual purposes: optimizing injection design and verifying carbonate formation. The strategy positions the Sam site as a scientifically robust, scalable model for CO2 sequestration, advancing CO2 Lock’s mission of transparent, permanent, and verifiable climate solutions.
