Why It Matters
A $100 million federal grant to Jervois signals a potential turning point for Idaho’s mining sector after decades of decline. The cobalt refinery project represents the Trump Administration’s push to rebuild domestic supply chains for materials critical to defense, aerospace, and semiconductor manufacturing—sectors where Idaho has emerging strength through companies like Micron.
What Happened
The U.S. Department of Energy awarded $100 million to Jervois, the company that operates the Salmon cobalt mine, to help construct the nation’s first domestic cobalt refinery. The mine itself shut down in 2023 after global cobalt oversupply made operations uneconomic, eliminating 300 jobs in the Salmon area.
The refinery will be built in either Pennsylvania or Louisiana rather than Idaho, though the grant reflects the Administration’s broader goal of restoring American mining and manufacturing capacity. Matthew Lengerich, president of Jervois USA, called the project significant for securing critical minerals domestically, noting it marks the first U.S. cobalt refinery “in over a generation.”
U.S. Assistant Secretary of Energy Audrey Robertson emphasized the strategic importance, stating that “reshoring that refining capacity and that supply chain here in the United States will make opportunities for economic mining come back to America.”, as first reported by the Local News 8
By the Numbers
- $100 million: federal grant amount, covering 40 percent of the estimated $250 million refinery construction cost
- 300: jobs lost when the Salmon mine closed in 2023
- 100: full-time employees expected at the new refinery
- Over 30 years: length of U.S. deindustrialization before this reversal began
Critical Uses for Cobalt
Cobalt is essential to modern manufacturing and defense. The metal is used in jet engines, semiconductor production, cell phones, artificial joints, paint, missiles, and battery technology. Its availability directly affects U.S. military readiness and technological competitiveness.
For decades, American manufacturers have relied on foreign cobalt sources, creating vulnerability in supply chains during geopolitical tensions. The refinery project directly addresses this dependency.
Idaho’s Emerging Role
While the refinery will operate out of state, the Salmon mine’s reopening potential anchors Idaho’s role in the supply chain. The grant signals confidence in the mine’s future as refinery demand increases, even though mine operations remain suspended pending favorable market conditions.
Idaho is positioning itself as a critical-materials hub. Micron’s $10 billion commitment to AI research in Boise and Idaho Power’s strategic divestment moves reflect the state’s attractiveness for advanced manufacturing and tech investment. A functioning cobalt supply chain would complement these broader economic developments.
Part of Broader Strategy
The cobalt refinery grant is part of the Trump Administration’s initiative to reverse 30 years of U.S. manufacturing decline through targeted federal investment in critical supply chains. The approach prioritizes reducing reliance on Chinese and foreign suppliers for materials vital to defense, energy, and technology sectors.
Similar federal initiatives have focused on semiconductor manufacturing, rare-earth processing, and battery production—industries where the U.S. lost capacity over the past generation.
What’s Next
Jervois will move forward with refinery site selection and construction planning. The timeline for reopening the Salmon mine depends on cobalt market conditions and refinery completion. Federal policy under the current Administration suggests continued support for domestic mining projects, particularly those involving critical minerals for national security.
