For the U.S., Minerals Are Now Geopolitics

Authors: Marta Rivera | Eduardo Zamanillo

In the past few weeks, Washington has stopped treating minerals as a cost curve problem and started treating them as a national-security input. Equity stakes, industrial deals, and a $7.4B Tennessee smelter are not “market plays.” They are a direct attempt to secure high-tech and defense continuity inside a more transactional supply chain order.

The structural question

The debate around critical minerals still defaults to the vocabulary of the old mining world: cost advantage, comparative economics, and the assumption that processing naturally migrates to the lowest cost jurisdictions.

That lens no longer fully explains what is happening.

In its recent 2025 National Security Strategy (NSS), the U.S. explicitly reframed industrial capabilities, supply chains, and technological dominance as core elements of national security. The state has clearly recognized that economic inputs, particularly minerals, represent critical strategic terrain. This transforms the logic behind minerals processing from a purely commercial pursuit to one centered on geopolitical continuity.

Once you accept that premise, decisions that appear economically irrational from a traditional mining perspective become entirely logical. The objective shifts from competing solely on global market price toward securing strategic resilience. Minerals now sit at the intersection of industrial strength, defense capability, and technological sovereignty.

What the U.S. is really securing

The clearest recent signal of this strategic pivot is Korea Zinc’s planned $7.4 billion critical minerals complex in Tennessee, a large scale refining and smelting project backed heavily by U.S. government financing and direct participation.

Critically, this facility is designed not as a single metal refinery but as a comprehensive platform for processing strategic by products and intermediates essential to semiconductors, defense, and advanced technologies. Planned outputs include gallium, germanium, indium, antimony, tellurium, and semiconductor grade sulfuric acid, alongside traditional base and precious metals.

Yet the strategic contest here is not only about plant capacity. It revolves fundamentally around control:

Feedstock security: access to concentrates, intermediates, secondary streams, and residues, materials often controlled by complex, opaque global trading arrangements.
By-product leverage: strategic value increasingly resides in minerals derived from residue circuits rather than primary ores. Controlling these secondary flows is critical.
Quality and purity assurance: especially for inputs required by defense and semiconductor manufacturers, securing precise, consistent material quality is non-negotiable.

Why Tennessee matters economically

Smelting and complex refining are power intensive operations. Electricity typically represents one of the largest cost items. Tennessee offers a meaningful advantage here. The state’s average industrial electricity price in 2024 was approximately 6.21 cents/kWh, among the lowest industrial rates nationally. Selecting Tennessee reduces the premium inherent in strategic midstream capacity, even if it does not erase it.

In other words, this choice demonstrates that while the U.S. no longer views minerals exclusively through a lowest-cost lens, economic factors like energy pricing remain relevant within the strategic framework.

The state as partner, not spectator

This strategic shift is not only rhetorical. Recent actions underscore Washington’s intent to reshape mineral supply chains actively. Alongside the Tennessee refinery, the U.S. government has taken equity stakes in companies like MP Materials (rare earths), Lithium Americas, and Trilogy Metals. These are no longer classic market interventions through subsidies alone. They represent direct state participation in the minerals value chain, intended to expedite timelines, reduce financial risk, and enhance geopolitical control.

The NSS explicitly connects these industrial interventions with broader hemispheric security. It states that the U.S. seeks a Western Hemisphere shielded from hostile foreign economic incursions and supportive of secure critical mineral supply chains. Moreover, it introduces the “Trump Corollary” to the Monroe Doctrine, explicitly identifying regional mineral supply access as a national interest, and pledging institutional reforms to expedite permitting and licensing.

This structural reframing matters greatly:

Critical minerals have moved squarely into national-security planning.
The state is transitioning from passive regulator to active industrial partner.
The Western Hemisphere is explicitly redefined as strategic depth for secure mineral supplies.

Additionally, investors must acknowledge China’s parallel diplomatic efforts in Latin America. Beijing’s December 2025 LAC Policy Paper explicitly ties diplomatic relationships to strategic alignment, highlighting the one China principle as foundational. This reminds us that securing feedstocks will inevitably involve navigating diplomatic and geopolitical alignment, not merely price competition.

The rise of security legitimacy

Another major shift underway is narrative legitimacy. For years, Western projects faced scrutiny primarily through ESG lenses, environmental impact, social license, community acceptance. Now, security is becoming an additional justification that governments use to underwrite strategic projects, despite higher costs.

Yet security narratives are no silver bullet. Permitting realities, community agreements, environmental management, and waste handling remain critical obstacles. Strategic imperatives can mobilize capital and accelerate policy, but they cannot erase domestic legitimacy constraints. The NSS explicitly acknowledges this, pledging to expedite domestic approvals to match strategic urgency.

Implications for capital and strategy: how investors should interpret this new U.S. posture

For investors and corporate decision-makers, analytical adjustments are necessary:

Accept strategic premiums: Understand that some supply chains will run at higher costs due to security priorities. Valuations will need to reflect sustained government backing and offtake stability rather than marginal cost dominance.
Follow state equity and partnerships closely: Government capital is now directly shaping mining outcomes. Monitor who controls feedstock and residue streams, as this will determine real strategic value.
Watch the hemisphere as a strategic unit: The NSS clearly indicates the Western Hemisphere as critical mineral strategic depth. Expect increased investment, diplomatic engagement, and transactional incentives for resource rich Latin American nations.
Realistic timelines and innovation cycles: While the U.S. can significantly accelerate technological innovation (refining techniques, automation, advanced materials), physical buildout – permitting, infrastructure, workforce – still takes years, even with state involvement. Be realistic about timelines, even if they shorten.

The deeper point

The deeper point is simpler: the U.S. is no longer treating critical minerals as “just another commodity” governed exclusively by the global cost curve. It treats them as strategic inputs, where continuity for defense, advanced manufacturing, and critical infrastructure justifies a strategic premium. The state is explicitly underwriting capacity, accelerating timelines, and actively shaping ownership structures to achieve this.

Yet even in this new posture, economics has not disappeared. Instead, economics have been reorganized around strategic security. Site selection, power costs, and disciplined execution will determine whether strategic capacity becomes durable, or remains merely symbolic.

And this is Geopolitical Mining, where minerals cease being mere commodities and become strategic infrastructure. A new paradigm where markets still price metals, but states price continuity.
