In episode two of my conversation with Simon Jowitt, we explore the ongoing geopolitical challenges facing the extractive sector. Whether it is global pandemics, competition with China, human rights challenges, or political insecurity in key mining regions, supply chains are facing increased political attention. It is becoming increasingly difficult as a geologist and mining engineer to be fully isolated to larger political dynamics at play across the mining sector going into the future. Simon also talks about his recent research looking at quantifying global critical mineral supply and some of the gaps and key pieces of evidence his team found during the process.
