Processing Challenges Threaten Western Mineral Reshoring Efforts, Says Legal Expert

According to mining lawyer Rebecca Seidl-Inglesby, Western governments face significant hurdles in their attempts to reshore critical-mineral supply chains. The primary constraint now lies not in sourcing ore but in the complexity of processing these materials into usable forms for manufacturers.

Seidl-Inglesby, who leads the critical minerals and metals practice at Baker Botts, points out a crucial timing mismatch in the mining cycle. An average copper mine requires approximately 17 years from discovery to initial production, with permitting processes potentially extending development timelines to nearly 30 years in the U.S. In contrast, demand from industries evolves rapidly, often measured in quarters. "When someone says reroute the supply chain, the raw material into that sentence is measured in decades, but the demand itself is measured in quarters," Seidl-Inglesby commented on The Northern Miner Podcast.

China currently refines about half of the world's copper and 90% of its rare earth elements, indicating that U.S. mined ore often ends up in Chinese processing facilities before it becomes available to manufacturers. Establishing sufficient refining and separation capacity within the West presents its own set of challenges—it's capital-intensive, slow to build, and environmentally taxing. After a processing plant begins operations, manufacturers may need an additional 18 to 24 months to certify and qualify its outputs for their needs.

This lag time illustrates why financing new mines might not lead to a significant rerouting of mineral supply chains. Without concurrent development of processing capacity and a network of qualified buyers, any new production remains tied to existing infrastructure that governments aim to shift away from.

Shift in Government Role

Seidl-Inglesby notes a significant evolution over the past two years: Western governments are increasingly acting as commercial partners rather than merely grant-making bodies. This change allows them to take equity stakes, guarantee offtake agreements, set price floors, and build strategic stockpiles. Such measures are essential since many strategic projects require revenue certainty as much as they do construction capital.

The U.S. has broadened its toolkit extensively, utilizing various departments, including energy, defense, and commerce, to enhance funding avenues through federal credit programs and the Office of Strategic Capital in the energy department.

As an exemplar of this new commercial approach, Seidl-Inglesby cites MP Materials (NYSE: MP), illustrating how the Pentagon combined a price floor, a decade-long offtake agreement, along with loans and equity investments to become the company’s largest shareholder. She anticipates that similar structures will be integral to future strategic minerals deals. However, government-backed investments often come with conditions, such as clawbacks, domestic-content mandates, and transfer restrictions, which can shape future business dynamics.

It’s crucial for companies to be aware of the implications of government equity investments, leading them to conduct diligence akin to assessing debt due to these obligations. Yet, the critique that such involvement constitutes "picking winners" assumes that a transparent market exists, which Seidl-Inglesby challenges. Instead, she argues that mineral pricing operates within a complex framework heavily influenced by dominating state actors wielding leverage over supply.

Establishing price floors and offtake agreements can provide the revenue clarity necessary for attracting private investors rather than merely replacing private funding with public capital. On the issue of stockpiling as a potential fix, she expresses caution, pointing to the necessity of a foundational stockpile before initiating Project Vault efforts aimed at reducing reliance on China.

Criteria for Funding

Projects poised to attract strategic investment are increasingly defined by their commercial viability rather than merely geological potential. Investors and governmental entities seek creditworthy offtakers with credible pricing mechanisms, nearly completed permitting processes, definitive plans for processing and qualification, and capital structures resilient to foreign-investment scrutiny. A legacy shareholder could disqualify an otherwise viable project from receiving federal funding.

As such, possessing a mineral deposit alone is insufficient; what's now in demand is the ability to demonstrate a credible pathway to connect that deposit to a refinery and eventually to a customer. In Seidl-Inglesby’s words, "A mine without a refinery and a customer risks becoming a stranded asset." The push for commercial integration becomes even more pronounced as manufacturers like Stellantis, Volkswagen, General Motors, and Ford now seek equity positions and offtake contracts in mineral projects—an arrangement far less common a decade ago.

For explorers aiming to attract strategic partnerships, Seidl-Inglesby advises preparation: establish clear ownership, maintain unencumbered offtake rights, and clarify the project's role in the supply chain. "The contest is increasingly won or lost long before a mine reaches production," she asserts. "If you can articulate your position within an integrated system, that’s financeable."

Going forward, the model indicates that Western mineral security hinges less on the number of deposits financed and more on the ability to construct a comprehensive commercial chain around those resources. While mines supply raw materials, it’s the presence of competent refining capabilities, reliable customers, and steady demand that will ultimately determine the escape from China-centric supply chains.
