Minerals are not mere inputs to the global economy, they are its bedrock, its physical foundation, and that foundation is under strain. The world is approaching a tipping point. Rapid global economic development, rising incomes, urbanisation, electrification, and the accelerating deployment of advanced technologies are driving mineral demand to levels the modern mining system was never designed to meet. Yet political, economic, and technological elites continue to treat resource availability as a given, assuming that higher prices, financial capital, or innovation alone can conjure supply when it is needed. The Mineral Imperative exposes why that assumption is dangerously wrong. Drawing on twenty-five years of experience across mining, finance, and industrial policy, Amanda van Dyke shows how declining ore grades, long development timelines, geopolitical fragmentation, and chronic underinvestment have collided to create a structural supply crisis. Theoretical reserves are not the same as economically viable supply, and despite rising prices, global mining output is failing to grow at a pace capable of sustaining current trajectories, let alone future ambitions for electrification, digitalisation, and energy transition. This book reveals the widening gap between mineral demand and mineral reality. It dissects the weaknesses embedded in Western supply chains, charts the rise of new mineral powers, and explains why mining, on its current path, cannot scale fast enough to prevent scarcity and volatility from becoming the new normal. Clear-eyed, urgent, and deeply researched, The Mineral Imperative is a call to abandon complacency and confront the material limits shaping the twenty-first century. It argues that avoiding chronic shortages will require a fundamental shift in how societies value, permit, finance, and partner with mining. This is a book about the world as it truly is, and the hard choices required to secure the one we are trying to build.
