Carbon Capture and sequestration: CNC advantages.... I was looking at Clean Air Metals press release this am {see below} and was wondering if CNC has a major advantage in capturing the Co2? Because of the extra costs involved in the capture, storage, etc I would think being low grade and therefore having to move tons of soil and earth , taillings, might give CNC an advantage in making the investment into the process as opposed to high grade and underground deposits where the return on investment would logically be much less dealing with only a fraction of the excavation volumes CNC would ?
Below is part of their news release.
GLTA again today. I have a cautious positive gut feeling of a much better close today.

Carbon Capture and Carbon Sequestration
Carbon capture and carbon sequestration are becoming more relevant to all industries as society strives to a net zero impact to the environment. Carbon capture is the trapping of carbon emissions after they have been emitted but before they enter the atmosphere. Carbon sequestration is the storage of removed or captured carbon in various environmental reservoirs.
The carbon sequestration potential of ultramafic mine tailings has been recognized previously at multiple operations. Mining operations that produce ultramafic rock tailings have the potential advantage of sequestering CO2 into the waste material. Carbon sequestration into exposed tailings has a two-fold benefit; 1) reducing carbon foot print associated with the mining process through CO2 sequestration and 2) potential stabilization of tailings by the formation of secondary magnesium carbonate minerals that can act as a cement within the tailings after they are deposited.
Clean Air Metals has initiated a number of studies, including specialty testing at world-class research facilities, to better understand the carbon sequestration potential of the waste rock and mill processing tails at Thunder Bay North. A Master of Science research project at Lakehead University is looking at the effects of hydrothermal alteration on the mineralized ultramafic rocks and characterizing the magnesium alteration products to identify potential reactive mineral species. Results to date show that the ultramafic and mafic rock units and minerals at Thunder Bay North successfully capture and sequester CO2 gas from the atmosphere.
