Why are net present value models fundamentally unsuitable for the mining industry?
NPV models were designed for oil fields declining over 10 years, not mines with century-long reserves. A 100-year copper mine valued under NPV must be resold for one penny in year 11, making the model economically nonsensical for assets with multi-decade production horizons and no built-in depletion curve matching oil's natural decline.
The core problem runs deeper than a simple accounting mismatch. When the Seven Sisters oil companies created NPV models in the mid-twentieth century to evaluate field swaps, they built in assumptions tied to energy physics: oil fields genuinely lose productive capacity over time as subsurface pressure drops and extraction becomes harder. That 10-year valuation window made sense because the asset itself was fundamentally degrading.
Copper and other minerals behave entirely differently. A mineral deposit does not lose its energy or inherent value just because ten years have passed. The copper still sits in the ground, chemically unchanged, worth the same physical commodity whether you mine it in year 5 or year 50. Yet NPV models force you to account for this by artificially crashing the asset value to nearly zero after the initial projection period—a mathematical fiction with no basis in geology or economics.
The practical consequence is stark and explained in detail in the episode: mining companies cannot justify long-term investment in mine infrastructure, exploration, or processing capacity because the financial model systematically undervalues anything beyond decade one. This forces poor capital allocation across an industry that, by its nature, operates on century-scale timelines.
"The mining industry is the dumbest business on planet Earth. It's a business for complete idiots because they've been ruled by net present value models for the last 20 or 30 years."
Robert Friedland — Executive Co-Chairman of Ivanhoe Mines and Co-Founder, Chairman, and CEO of I-Pulse. Friedland has spent 45 years in the mining business, including operating a copper mine in Myanmar when prices stood at 62 cents per pound. He is recognized for his deep expertise in critical metals strategy and long-cycle asset valuation in the mining sector.
What makes this critique particularly urgent is the geopolitical moment: as Friedland discusses in the podcast, the world faces an unprecedented demand for copper, lithium, cobalt, and rare earths to power energy transitions, electrification, and defense systems. Yet the valuation framework that controls mining investment decisions systematically penalizes the long-term mine development that supply security actually requires. The mismatch between NPV's 10-year horizon and mining's 50-100 year reality is not a technical quibble—it's a structural barrier to rational capital allocation in a critical industry.
Key takeaways
- NPV models originated from oil company swaps and assume asset decline over 10 years—a pattern unique to oil fields losing pressure, not mineral deposits.
- Under NPV logic, a 100-year mine must have its valuation collapse to near-zero in year 11, regardless of the commodity's actual physical value underground.
- This forces mining companies to underinvest in long-term infrastructure and exploration because the financial model cannot capture value beyond the initial decade.
- The mismatch between NPV's short time horizon and mining's century-scale asset life creates perverse incentives in an industry critical to global energy and defense supply.
