Peter Harvey: Mine Closure and the True Cost of Metals

Mine Closure and the True Cost of Metals

Mine closure is one of the biggest unsolved challenges in responsible mining, and Peter Harvey has spent the last seven years at the heart of it. His route was unusual: environmental science, then outdoor education for young people excluded from school (companies he still directs), a master's in occupational psychology, and a decade enabling mineral exploration across West Africa, Asia and beyond, before seventeen years at Rio Tinto spanning exploration, operations and closure.

His argument cuts to the core of sustainable mining: the true cost of extraction has never been in the price of the metal. We pay to pull minerals from the ground, not to clean up what's left, a closure liability the major mining companies alone value at over ninety billion dollars, and one few have any incentive to disclose. Design a mine with the end in mind, he argues, and you cut long-term liabilities and leave land genuinely fit for its next use.

This episode also covers mine rehabilitation and post-mining land use, the sector's culture of poor transparency, who belongs at the table (governments, financiers, and Indigenous and First Nations communities), and a Navajo approach to planning seven generations ahead.
