(Kitco News) A widening capital shortfall in copper is reshaping how large-scale projects are financed, with royalty and streaming companies emerging as pivotal sources of funding, according to veteran metals investor Rick Rule.
“The copper industry requires at least $250 billion in capital expenditure over the next 10 years to maintain current levels of output,” said Rule, President and CEO of Rule Investment Media, speaking on Kitco Mining’s Digging Deep. “That capital at today’s copper prices is currently unavailable.”
Rule framed the figure not as growth spending but as replacement capital needed to offset grade decline, input cost inflation and rising fiscal demands. With traditional balance sheets constrained, he said, alternative financing structures are likely to expand.
The shift was underscored when Wheaton Precious Metals announced a $4.3 billion silver stream with BHP tied to the Antamina mine in Peru. Rule said the transaction reflects a structural valuation gap between streaming companies and diversified miners.
Precious metals revenue embedded in royalty or streaming vehicles can trade at 15 to 20 times cash flow, he said, while similar cash flows housed within multi-commodity base metal producers often trade at five to seven times cash flow. “There’s sort of a financial alchemy that takes place,” Rule said, adding that the Wheaton-BHP agreement may represent “the first transaction of many transactions.”
Rule suggested the next phase could involve streaming companies tapping long-dated debt markets, “I think what you're going to see is the issuance by Franco (Nevada) and Wheaton of 20 and 30-year bonds,” he said. By securitizing multi-decade streams, he argued, royalty companies could further reduce their cost of capital and recycle funds into additional large-scale transactions.
Project economics illustrate the strain, with Lundin Mining and BHP’s recent news of an integrated preliminary economic assessment for the Vicuña copper project in Argentina, outlining a staged development with an initial capital cost of about $7.1 billion. The study reported a base case internal rate of return of 14.8% at assumed prices of $4.60 per pound of copper, $3,300 per ounce of gold and $40 per ounce of silver.
Rule described Vicuña as “the most important copper discovery on a global basis since Kamoa Kakula,” but cautioned that hurdle rates near 15% underscore the difficulty of financing even world-class deposits. “If the most exciting copper discovery on the planet can't get built” at recent prevailing metal prices, he said, it may imply a structural floor under long-term copper pricing.
Sovereign policy adds another layer of risk. Rule pointed to Argentina’s Regime for Incentives to Large Investments, known as RIGI, as central to any financing package, noting that guarantees around fiscal stability, royalty structures and capital repatriation would be required before construction decisions proceed. Cross-border infrastructure, including potential water supply and export routes through Chile, may further shape capital requirements.
In the United States, Rule drew a distinction between federal policy signals and individual project outcomes. “This is the best permitting environment that we've seen in the last 30 years” at the federal level, he said, even as the Department of Justice in mid-February filed a brief defending the Environmental Protection Agency’s 2023 veto of Alaska’s Pebble project.
Taken together, Rule said the defining constraint on copper supply is less geology than capital intensity and the cost of financing. As the sector confronts a $250 billion replacement bill over the coming decade, he suggested that financial innovation, not just higher prices, may determine which projects advance.
