Rare Earth Mining Companies in the USA: Two Distinct Paths to Critical Mineral Production

The race to establish domestic production of critical minerals has become increasingly important for the United States, driven by surging demand from the electric vehicle industry, renewable energy sectors, and advanced technology applications including artificial intelligence. Two prominent rare earth mining companies—USA Rare Earth (USAR) and NioCorp Developments (NB)—are pursuing markedly different strategies to capture opportunities in this high-growth market, each presenting unique advantages and challenges for investors considering exposure to this sector.

The Critical Minerals Boom Shaping USA’s Mining Landscape

The geopolitical and economic drivers behind critical mineral demand have created unprecedented opportunities for domestic rare earth mining companies across North America. Electric vehicles require substantial quantities of rare earth elements for motor magnets and other components, while renewable energy installations depend on these materials for permanent magnets in wind turbines. Beyond these traditional markets, emerging technologies and defense applications continue to expand the addressable market for companies positioned to supply these essential inputs.

This tailwind has created a competitive environment where established players and new entrants alike are racing to develop production capacity. The challenge, however, lies in the capital intensity and technical complexity of bringing mining operations to commercial scale. Both USAR and NB have recognized these opportunities, but they’ve elected to pursue materially different approaches to capturing market share in this evolving landscape.

USAR’s Concentrated Bet: Building America’s Magnet Manufacturing Hub

USA Rare Earth has oriented its strategy around a single, focused objective: establishing the Stillwater facility in Oklahoma as a major domestic manufacturing center for Neodymium Iron Boron (NdFeB) magnets. This specialization reflects a deliberate choice to address a critical bottleneck in the American rare earth supply chain.

The company’s development trajectory shows concrete progress toward commercialization. During the latter stages of 2025, USAR accelerated its facility preparation, installing manufacturing equipment and commencing assembly of its initial production line. The company simultaneously began recruiting and training the specialized engineering and technical workforce required to operate such a sophisticated facility. Management has communicated a target of early 2026 for commissioning Line 1a, with subsequent phases designed to scale total production capacity to approximately 1,200 metric tons of NdFeB magnets annually.

Financially, USAR strengthened its position considerably through various capital-raising activities. By the end of Q3 2025, the company had accumulated over $400 million in cash reserves through PIPE financing and warrant exercise proceeds. This financial cushion is being deployed strategically: upgrading the Stillwater installation, expanding downstream magnet finishing capabilities, and completing construction of Line 1b. Additionally, the company’s acquisition of Less Common Metals in late 2025 addressed a key supply chain vulnerability by securing reliable access to critical metal and alloy feedstocks necessary for magnet production.

However, this aggressive expansion trajectory carries notable risks. USA Rare Earth remains a pre-revenue enterprise, having incurred accumulated losses throughout its operational history. More concerning, operating expenses have accelerated dramatically—selling, general, and administrative costs surged to $11.4 million in Q3 2025 from just $0.8 million in the prior-year quarter—driven by elevated legal and consulting outlays, workforce expansion, and recruitment expenses. This cost escalation raises questions about the company’s path to profitability once the Stillwater facility reaches commercial operation.

NioCorp’s Diversified Strategy: A Broader Mineral Portfolio

By contrast, NioCorp has charted a different course, targeting the Elk Creek Project in Nebraska as a multi-mineral production platform. Rather than focusing exclusively on magnet materials, this operation would generate niobium, scandium, titanium, and rare earth elements—a portfolio that addresses demand across electric vehicles, clean energy infrastructure, and defense applications.

NioCorp has made tangible strides in advancing this initiative. The company’s board granted approval for the Mine Portal Project in December 2025, a foundational step toward moving Elk Creek into full production. Concurrent with this green light, NioCorp acquired additional acreage in Johnson County, Nebraska, consolidating its land holdings to approximately one square mile at the project site—sufficient to accommodate both surface processing infrastructure and the underground mining operation. Furthermore, a contractual relationship with the U.S. Department of Defense is providing engineering support and facilitating drilling activities, which enhances the project’s credibility and pace of advancement.

The capital challenge, however, looms large. NioCorp required $60 million in fresh capital, which it raised through equity offerings in fall 2025. While this injection of cash supports near-term development activities, the dilutive effect on existing shareholders merits consideration. More critically, the company has estimated that moving the Elk Creek Project into production will require approximately $1.1 billion in additional funding—a formidable hurdle that may necessitate combinations of project financing, government support (the company is exploring loan possibilities through the U.S. Export-Import Bank under the “Make More in America” program), and potentially further equity dilution.

Financial Metrics: Comparing Investment Profiles

The two companies’ financial forecasts present a sobering picture for near-term profitability. Zacks consensus estimates project that USA Rare Earth will record a loss of $0.65 per share in 2025, while NioCorp is anticipated to deliver a loss of $0.68 per share—suggesting comparable levels of near-term cash burn and operational challenges.

Stock market dynamics, however, have diverged recently. In the month prior to early February 2026, USAR shares appreciated 26%, while NB stock advanced 16.2%, indicating that investors have distinguished between the two on growth trajectory or risk considerations. From a valuation perspective, USAR trades at a forward P/E multiple of negative 42.72x, whereas NioCorp’s forward multiple stands at negative 13.04x—both reflecting the speculative nature of pre-revenue mining developers, though NB’s less extreme negative multiple may suggest somewhat lower risk premiums assigned by the market.

Which Rare Earth Mining Company Offers Superior Prospects?

The answer hinges significantly on one’s investment time horizon and risk tolerance. NioCorp is building what could become a cornerstone supplier of multiple critical minerals to essential industries, and its long-term potential should not be dismissed. However, the $1.1 billion funding requirement represents a substantial challenge; securing this capital while maintaining reasonable shareholder dilution will require patience, market cooperation, and possibly continued government support.

USA Rare Earth, conversely, appears closer to demonstrating whether its capital-intensive Stillwater magnet manufacturing facility can achieve the operational and financial turnaround that its business model requires. The focused strategy reduces complexity and the concentrated efforts around magnet production position the company for potential transformation upon reaching commercial operation. Yet the absence of revenue generation and the accelerating cost structure present material headwinds in the near term.

For investors evaluating domestic rare earth mining companies, USAR currently emerges as the more compelling opportunity relative to NB, given its proximity to production milestones and more concentrated risk profile. This assessment is reflected in Zacks’ assigned ratings: USAR carries a Rank of #3 (Hold), while NioCorp holds a #4 (Sell) rating, underscoring analytical consensus that the former mining company presents a less encumbered pathway toward value creation at this juncture.
