Mining royalty and streaming companies could be the key financiers for a sector facing rising capital costs of precious and critical metals.
The business model is straightforward. A streamer provides upfront capital to a mine operator, often without taking equity, in exchange for the right to buy future production at a fixed or discounted price. In many cases, the metal is a byproduct — silver or gold from a copper mine — that a diversified operator may not receive full market credit for.
Once a project clears completion testing, the streamer's exposure changes dramatically. It typically has no obligation to fund sustaining capital, exploration or operating cost inflation. That approach creates an advantage as miners struggle with labor shortages, higher construction costs and permitting delays.
In a recent interview, Wheaton Precious Metals Corp. (NYSE:WPM) CEO Haytham Hodaly said the structure remains built around long-life, low-cost mines in stable jurisdictions. About 80% of the company's portfolio sits in the lower half of the cost curve, helping ensure the operators keep the assets producing through downturns.
“We come in, and we support these companies without taking equity,” Hodaly said.
A Bigger Deal Book
The scale of the opportunity has changed. Wheaton's $4.3 billion silver stream on BHP Group Limited's (NYSE:BHP) share of the Antamina copper-zinc mine in Peru signaled a new era of mega-deals.
Antamina highlights the due-diligence edge streamers seek. “What the market views as a 10 or 12 year-life,” Hodaly said, may in Wheaton's assessment continue for another 30 to 50 years.
He believes Wheaton could complete roughly one transaction of that size annually over the next three to four years, supported by about $2.7 billion in annual free cash flow and more than $2.5 billion of revolving-credit capacity. Hodaly is also very optimistic on silver.
“We feel silver longer term is going to go higher, much higher as well,” he said.
Closing the Capital Gap
Royalty producers traditionally worked with precious metals, but veteran investor Rick Rule says the next wave might come from copper.
The largest producers, he said, need about $250 billion just to sustain current output, creating a financing gap that conventional debt and equity cannot fill.
That dynamic makes streams attractive. Silver cash flow buried inside a base-metal miner may be valued at six or seven times cash flow, Rule said, but the same cash flow inside a dedicated streamer can trade near 15 times.
“This is a true win-win transaction,” he said of Antamina.
Rule expects $30 billion to $75 billion of unconventional finance to be needed, with major streamers leading syndicates that may include mid-tier royalty companies and private funds. Yet, he warned that rapid dealmaking without a structural advantage can signal overpayment.
The Operator's Pushback
Still, not every mine builder is enthusiastic. McEwen Inc. (NYSE:MUX) founder and chairman Rob McEwen has long criticized the model, warning that royalties and streams weaken operators by giving away future margins.
“They lose their resilience in a lower market,” McEwen said. In an earlier interview, he compared the model to a “siren on the rocks that beckons the sailors.”
Still, he acknowledged the investor appeal. For those seeking lower-risk exposure to gold or silver, “you'd probably look at a royalty company or a streaming,” he clarified.
