Deep-Sea Mining: Environmental Disaster or Necessity? ft. Stan Sudol

Could deep-sea mining solve the West’s critical-mineral shortage without destroying ecosystems?

Stan Sudol explains why mining the ocean floor may be less damaging than the alternatives.

In this episode, we break down:

• How deep-sea mining works and why polymetallic nodules contain valuable nickel, copper, cobalt, and manganese
• Why The Metals Company is pursuing mineral extraction in the Clarion-Clipperton Zone of the Pacific Ocean
• The environmental debate over collecting seabed nodules thousands of metres below the surface
• Why deep-ocean mining could have a smaller physical footprint than some conventional open-pit mining projects
• How rising demand from EVs, AI data centres, electrical grids, defence and industrial development is increasing pressure on critical-mineral supplies
• Why the United States is exploring a more aggressive approach to seabed mining and mineral security
• China’s growing expertise in deep-sea technology, mineral processing and strategic-resource supply chains
• Canada’s cautious position on seabed mining and the debate over moratoriums and environmental regulation
• The economic and technical challenges facing commercial-scale deep-sea mining
• Whether ocean-floor resources could reduce Western dependence on China and other foreign mineral suppliers
