The silver mining industry's inability to increase output despite record prices above $70/oz is a critical structural feature of the market. Global mine production has been essentially flat at approximately 26,000 tonnes per year for the past five years, even as prices have more than doubled.
The primary constraint is that approximately 70% of silver production is a by-product of copper, lead, and zinc mining. Silver output from these operations is determined by base metal production decisions, not silver prices. Even as silver prices rally, by-product silver production cannot increase without a corresponding increase in base metal output.
Primary silver mines, which account for the remaining 30% of supply, have struggled with declining ore grades and longer development timelines. Major primary silver operations in Mexico — the world's largest silver producer — have seen average ore grades decline by 15-20% over the past decade.
New silver mine development faces significant hurdles. The average time from discovery to production is 10-15 years, and permitting challenges have lengthened timelines further. Several advanced-stage projects in Mexico, Peru, and Argentina face local community opposition and environmental review delays.
The lack of supply response to high prices is a textbook example of inelastic supply in the mining industry. This structural constraint means that demand growth — particularly from the solar and electronics sectors — will continue to drive prices higher over the long term.
The supply inelasticity means silver prices have significant upside potential as industrial demand grows. Buyers cannot rely on supply response to moderate prices. Aggressively hedge forward requirements and consider long-term supply agreements.
