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.
