Understanding how different fluids move through rocks at the Tamarack site is important for deciding if we can use CO₂ to help extract valuable minerals from underground. In this study, we used high-resolution X-ray scanning to look inside ten rock samples from Tamarack and to measure details like pore size, shape, and how much empty space (porosity) the rocks have. We turned these scans into computer models that allowed us to simulate how CO₂ and water would flow together through the rocks. We then compared these simulation results to real laboratory measurements, finding that they matched well. Our findings show that these Tamarack rocks allow CO₂ and water to move through them effectively, supporting the idea that CO₂-based methods could be used to recover critical minerals here. This research gives detailed, small-scale insights that could help design better ways to use CO₂ for mining at Tamarack.
