FPX Nickel Subsidiary CO2 Lock Corp. Achieves Successful Injection Of CO2 At SAM Project In British Columbia - Carbon Herald

FPX Nickel Corp. is pleased to provide an update on the activities of CO2 Lock Corp., its majority-owned subsidiary specializing in carbon capture and storage (CCS) via permanent mineralization. CO2 Lock has completed a comprehensive field program at its SAM site in central British Columbia, including the first-ever successful injection of CO2 into a brucite-rich ultramafic mineral project. This achievement marks a significant milestone in the development of CO2 Lock’s innovative in-situ CO2 mineralization technology.


  • Successful injection of CO2 at depth, with downhole sensors verifying the desired CO2 content throughout the carbonated water injection, bolstering confidence in the effectiveness of CO2 Lock’s proprietary approach
  • Geological analysis confirms that the SAM deposit has promising mineralogy for CO2 mineralization and permanent storage, with high values of brucite (key carbon-reactive mineral)
  • Extraction of multi-tonne surface bulk sample for use in an ex-situ COmineralization pilot at CO2 Lock’s laboratory in the Vancouver area

“The promising geological analysis and successful demonstration of the CO2 injection into the SAM project highlight the significant potential of CO2 Lock’s in-situ mineralization technology,” commented Martin Turenne, FPX’s President and CEO. “We look forward to seeing CO2 Lock’s next steps in advancing its proprietary approaches to both in-situ and ex-situ carbon mineralization at its SAM project.”

  • In-Situ Mineralization: The injection of CO2-enriched water into the subsurface prompts the release of magnesium from the brucite-rich serpentinite host rock; the liberated magnesium subsequently reacts with the injected CO2, leading to the formation of stable carbonate precipitation.
  • Ex-Situ Mineralization: Brucite-rich serpentinite rock is extracted and undergoes processing for three distinct CO2 mineralization options: stacked rock, enhanced rock weathering, or reactor-based mineralization.

In 2024, CO2 Lock will conduct several work programs to advance its proprietary approaches to carbon mineralization, including the preparation of techno-economic and life-cycle assessments of the in-situ and ex-situ technologies, and the completion of an ex-situ pilot program using material collected from the SAM project.

On March 30, 2022, FPX announced the formation of CO2 Lock as a self-funding subsidiary entity to pursue geoscience-related CCS opportunities. FPX retains 100% of the carbon credits associated with CCS on its own properties, and can use any intellectual property developed by CO2 Lock for the benefit of FPX’s own properties.
