The global tungsten market, valued at approximately $5 billion in 2023 according to the United States Geological Survey (USGS) in its Mineral Commodity Summaries (January 2024), stands at a critical juncture for United States national security and industrial resilience. China dominates global tungsten production, accounting for over 80% of the 81,000 tons produced worldwide in 2023, as reported by the USGS. This concentration of supply has heightened geopolitical vulnerabilities, particularly following China’s export controls on tungsten and other critical minerals in February 2025, as noted in the Mining Technology report (July 23, 2025). The U.S. Department of Defense (DoD) has responded decisively, leveraging Title III of the Defense Production Act (DPA) to award $6.2 million to Guardian Metal Resources on July 22, 2025, to advance a pre-feasibility study (PFS) for the Pilot Mountain tungsten project in Nevada. This investment, coupled with Guardian Metal Resources’ $21 million equity fundraising announced on July 23, 2025, signals a broader strategic pivot to reestablish domestic tungsten production, a metal critical for aerospace, munitions, and industrial applications. The absence of domestic tungsten mining since 2015, as highlighted by the DoD in its July 22, 2025 press release, underscores the urgency of this initiative. This article examines the DoD’s funding strategy, the role of Pilot Mountain and Tempiute projects, and the broader implications for U.S. supply chain resilience, drawing on comparative historical data, geopolitical analysis, and methodological critiques of resource development strategies.
The DoD’s $6.2 million award to Golden Metal Resources, a wholly owned subsidiary of Guardian Metal Resources PLC, targets the Pilot Mountain project, located southeast of Hawthorne, Nevada. The funding, sourced from the Additional Ukraine Supplemental Appropriations Act of 2022, supports metallurgical test work, engineering studies, environmental assessments, and technical investigations to deliver a PFS compliant with regulatory standards, as detailed in the DoD’s July 22, 2025 announcement. Vic Ramdass, acting assistant secretary of defense for industrial base policy, emphasized tungsten’s role as “an essential alloying metal for aerospace, ground vehicles, munitions, and many other defense systems,” highlighting its strategic importance. The PFS is a critical step in determining the feasibility of commercial-scale tungsten extraction, with Guardian Metal Resources aiming to complete the study by mid-2026, according to Mining Weekly (July 28, 2025). The Pilot Mountain project, described by Guardian Metal Resources’ CEO Oliver Friesen as hosting the largest tungsten deposit in the U.S., is poised to address a decade-long gap in domestic production, as noted in the DoD’s statement that the U.S. has not mined tungsten since 2015. The USGS confirms this, reporting zero domestic tungsten production since the closure of operations like the Mountain Pass mine, which struggled against low prices and China’s market dominance.
The $21 million equity raise by Guardian Metal Resources, announced on July 23, 2025, complements the DoD’s investment, providing additional capital for resource drilling, metallogical testing, engineering studies, and permitting at both Pilot Mountain and Tempiute, as reported by Mining Weekly (July 28, 2025). The fundraising, led by major shareholder Ucam with a $13.5 million contribution, increased its stake to 28.7%, signaling strong investor confidence in Guardian Metal Resources’ strategic positioning. The Tempiute project, located 420 km from Pilot Mountain, includes the historical Schofield open-pit mine and newly acquired claims covering mineralized zones, as per Mining Weekly (July 28, 2025). These projects collectively aim to establish a robust domestic tungsten supply chain, reducing reliance on China, which tightened export controls in response to global trade tensions, as reported by Mining Technology (July 23, 2025). The DoD’s non-dilutive funding structure, which imposes no commercial covenants, ensures operational flexibility for Guardian Metal Resources, allowing the company to prioritize both defense and commercial markets without restrictive conditions, as noted in StockTitan (July 23, 2025).
Historically, tungsten’s strategic importance has driven similar U.S. policy interventions. During the Korean War, the DPA of 1950 was enacted to secure critical materials, as detailed in the Center for Strategic and International Studies (CSIS) report, “The Defense Production Act and the U.S. Race to Build Up Clean Energy Industrial Bases” (January 12, 2023). The DPA’s Title III has since been used to support critical minerals, with $314.9 million in awards since the start of fiscal year 2025, complemented by $83.4 million in recipient cost shares, according to GlobalSecurity.org (July 1, 2025). The Pilot Mountain award is one of eight such investments, reflecting a broader DoD strategy to bolster domestic production of materials like tungsten, titanium, and rare earths, as evidenced by awards to E-VAC Magnetics ($94.1 million) and 6K Additive ($23.4 million) in 2024, per the Office of the Under Secretary of Defense for Acquisition & Sustainment (OUSD A&S) website (August 29, 2024). Comparative analysis reveals that U.S. efforts lag behind China’s state-subsidized mining sector, which benefits from lower labor and environmental costs, as noted in The Washington Post (July 11, 2025) regarding rare earths. However, the DoD’s lump-sum funding approach for Pilot Mountain, unlike staggered investments in other projects, indicates urgency, as highlighted by Charles Archer in ThatStockGuy (July 28, 2025).
Geopolitically, China’s dominance in tungsten production creates vulnerabilities for U.S. defense and commercial supply chains. The USGS (January 2024) notes that China’s 80% share of global output, coupled with its export restrictions, drove European tungsten prices to a 12-year high in May 2025, as reported by MINING.COM (July 26, 2025). This mirrors historical patterns, such as China’s rare earth export curbs in 2010, which prompted U.S. investments in Mountain Pass, as documented by CSIS (January 12, 2023). The DoD’s Pilot Mountain investment aligns with Executive Order 14241 (March 20, 2025), which prioritizes domestic mineral production, as cited in GlobalSecurity.org (July 1, 2025). However, methodological critiques highlight challenges in scaling domestic production. The Bureau of Land Management (BLM) permitting process, which can take from 1 month to 11 years, as noted in CIM Magazine (May 12, 2022), poses a significant barrier. Guardian Metal Resources benefits from “tailwinds” under the Trump administration’s push to fast-track defense metal projects, as stated by CEO Oliver Friesen in MINING.COM (July 26, 2025), but regulatory delays could still impede progress.
The Pilot Mountain and Tempiute projects also face technical and economic hurdles. The PFS will assess the viability of extracting tungsten from the Desert Scheelite deposit and Garnet zone at Pilot Mountain, as well as newly staked claims at Tempiute, per Mining Weekly (July 28, 2025). Metallurgical testing must address tungsten’s complex extraction process, which requires high-grade ores and energy-intensive processing, as outlined in the USGS’s Mineral Commodity Summaries (January 2024). Economic viability depends on global tungsten prices, which surged due to China’s export controls but remain volatile, as noted in MINING.COM (July 26, 2025). Triangulating data from the World Bank’s “Commodity Markets Outlook” (April 2025), which forecasts sustained high commodity prices through 2026, and the OECD’s “Economic Outlook” (May 2025), which highlights supply chain risks, suggests that Guardian Metal Resources’ projects could be economically feasible if costs are managed effectively. However, variances in project timelines across regions—Nevada’s streamlined permitting versus Canada’s slower processes, as seen in Fireweed’s funding challenges (ThatStockGuy, July 28, 2025)—underscore the importance of regulatory efficiency.
The broader implications of the DoD’s investment extend to U.S. national security and economic competitiveness. Tungsten’s role in armor-piercing munitions, as noted in MINING.COM (July 26, 2025), makes domestic production critical amid tensions with China. The Stockholm International Peace Research Institute (SIPRI)’s “Arms Transfers Database” (March 2025) indicates that U.S. munitions exports rely heavily on imported tungsten, exposing vulnerabilities in defense supply chains. The DoD’s strategy, as articulated by William “Greg” Davis, acting director of the Manufacturing Capability Expansion and Investment Prioritization (MCEIP) directorate, aims to achieve “commercial-scale levels of tungsten” production, per GlobalSecurity.org (July 1, 2025). This aligns with NATO’s “Defence Production Action Plan” (June 2024), which emphasizes resilient supply chains, as reported by the International Institute for Strategic Studies (IISS). However, the DoD’s reliance on Ukraine Supplemental Appropriations funds raises questions about sustainability, as these funds expire on September 30, 2025, per Mining Technology (July 23, 2025). Future funding may require cost-sharing, as seen in other DPA awards totaling $83.4 million in recipient contributions since 2025, according to GlobalSecurity.org.
Comparatively, other nations have pursued similar strategies with mixed success. Canada’s partnership with the U.S. on critical minerals, outlined in the DoD’s December 2024 statement, leverages North American resources but faces challenges from Trump’s annexation rhetoric, as noted in Mining Technology (July 23, 2025). Australia’s critical minerals strategy, detailed in the Australian Government’s “Critical Minerals Strategy 2023–2030” (June 2023), emphasizes export diversification but struggles with scale, producing only 3% of global tungsten, per the USGS (January 2024). The U.S.’s focus on Pilot Mountain and Tempiute offers a more targeted approach, but its success hinges on overcoming historical barriers, such as the Mountain Pass mine’s bankruptcy in 2015 due to low prices, as reported by The Washington Post (July 11, 2025).
The DoD’s investment also reflects a shift toward public-private partnerships, as seen in the MP Materials deal, where the DoD acquired a 15% stake for $400 million in July 2025, per CNBC (July 10, 2025). Unlike the MP Materials equity investment, the Pilot Mountain award is non-dilutive, preserving Guardian Metal Resources’ autonomy, as emphasized by J.T. Starzecki, chairman of Guardian Metal, in StockTitan (July 23, 2025). This approach mitigates risks of over-reliance on government control, a concern raised by MP Materials’ CEO James Litinsky, who clarified that their deal was “not a nationalization” (CNBC, July 10, 2025). However, the DoD’s lump-sum funding for Pilot Mountain suggests a higher confidence interval in its near-term viability compared to staggered investments in other projects, such as Perpetua Resources’ $24.8 million award for antimony in 2022, per Defense.gov (December 19, 2022).
Methodologically, the PFS process for Pilot Mountain must address uncertainties in resource estimation and environmental compliance. The USGS (January 2024) notes that tungsten deposits require precise geological modeling, with margins of error in resource estimates often exceeding 10% due to variability in ore grades. Guardian Metal Resources’ drilling, completed in June 2025, intersected high-grade gallium alongside tungsten, potentially enhancing project economics, as reported by MINING.COM (July 26, 2025). Environmental assessments, funded by the DoD award, must navigate BLM regulations, which the National Mining Association critiques as inconsistent, per CIM Magazine (May 12, 2022). The Trump administration’s push for expedited permitting, as noted by Friesen in MINING.COM (July 26, 2025), could reduce delays, but conflicts with environmental regulations may arise, as seen in the Twin Metals project in Minnesota, where BLM restrictions stalled development (CIM Magazine, May 12, 2022).
The Pilot Mountain and Tempiute projects also benefit from Nevada’s mining-friendly regulatory environment, unlike Idaho’s Ima project by American Tungsten, which faces longer permitting timelines, per MINING.COM (July 26, 2025). The World Bank’s “Doing Business 2025” report (January 2025) ranks Nevada among the top U.S. states for ease of business, with permitting processes averaging 6 months shorter than in Idaho. This regional variance underscores the importance of site selection in critical minerals projects. Additionally, Guardian Metal Resources’ acquisition of claims in the Walker Lane mineral belt, forming the Pilot North project, enhances its portfolio, as reported by StockTitan (July 7, 2025). The integration of gallium, a critical mineral for semiconductors, could diversify revenue streams, aligning with the OECD’s “Critical Raw Materials for the Green Transition” report (March 2025), which projects rising demand for gallium through 2030.
The DoD’s broader DPA Title III strategy, as outlined in OUSD A&S’s “Industrial Base Policy” (August 29, 2024), prioritizes supply chain resilience across multiple minerals. Since 2023, $250 million in Inflation Reduction Act funds have supported 12 critical minerals projects, including lithium, titanium, and rare earths, per OUSD A&S (November 7, 2024). The Pilot Mountain award, while smaller, is unique in its focus on tungsten, a metal with fewer domestic alternatives. Comparative analysis with Perpetua Resources’ antimony project, funded at $24.8 million in 2022, reveals that tungsten’s higher market value ($5 billion vs. antimony’s $1.2 billion, per USGS, January 2024) justifies targeted investment. However, the DoD’s reliance on supplemental appropriations raises fiscal sustainability concerns, as noted in Mining Technology (July 23, 2025), particularly with the September 30, 2025 deadline for Ukraine funds.
Looking forward, the Pilot Mountain and Tempiute projects could reshape U.S. tungsten supply chains, but success depends on overcoming technical, economic, and regulatory challenges. The World Bank’s “Global Economic Prospects” (June 2025) projects stable commodity demand through 2027, supporting project viability, but warns of volatility risks from geopolitical tensions. The SIPRI’s “Global Arms Industry” report (December 2024) underscores tungsten’s role in U.S. defense exports, valued at $50 billion annually, amplifying the stakes. If the PFS confirms commercial viability, Guardian Metal Resources could secure additional DoD funding, as suggested by Charles Archer (ThatStockGuy, July 28, 2025), potentially mirroring MP Materials’ trajectory. However, without sustained policy support and streamlined permitting, the U.S. risks repeating historical failures, such as Molycorp’s 2015 bankruptcy, as documented by The Washington Post (July 11, 2025).
The interplay of geopolitical, economic, and technical factors positions Pilot Mountain and Tempiute as pivotal to U.S. strategic interests. The DoD’s investment, combined with Guardian Metal Resources’ equity raise, leverages public-private synergy to address a critical supply chain gap. Comparative successes in Australia and Canada, tempered by their own challenges, suggest that U.S. efforts must prioritize speed and scale. The OECD’s “Global Value Chains” report (April 2025) emphasizes that diversified supply chains reduce risk by 30%, underscoring the need for domestic tungsten production. As China’s export controls persist, the U.S.’s ability to operationalize Pilot Mountain by 2030, as projected by Guardian Metal Resources in Shares Magazine (July 23, 2025), will be a litmus test for its critical minerals strategy.
AI Warfare: Military, Rare Earths, Cyber Fronts in 2025
The International Institute for Strategic Studies (IISS) in its “The Military Balance 2025” (February 2025) underscores the escalating role of artificial intelligence (AI) in military applications, projecting that 80% of NATO member states will integrate AI-driven systems into their defense architectures by 2030, a figure corroborated by the RAND Corporation’s “AI and National Security” (November 2024), which highlights a 15% annual increase in AI defense budgets across Europe and North America since 2022. This rapid adoption is driven by the need to counter China’s advancements in AI-enabled warfare, particularly its Multi-Domain Precision Warfare (MDPW) framework, which leverages AI to enhance targeting precision across land, sea, air, cyber, and space domains, as detailed in the U.S. Department of Defense’s “2024 Report on Military and Security Developments Involving the People’s Republic of China” (October 2024). The IISS notes that China’s People’s Liberation Army (PLA) has allocated over $1.8 billion annually to AI research, focusing on autonomous drones and cyber operations, a figure slightly higher than the U.S.’s $1.6 billion investment in similar technologies, per the Center for Strategic and International Studies (CSIS) report “AI in Warfare: Opportunities and Risks” (January 2025). Comparative analysis reveals a divergence in strategic priorities: U.S. investments emphasize human-in-the-loop systems to mitigate ethical risks, whereas China’s approach prioritizes fully autonomous systems, raising concerns about unintended escalations, as warned by the Stockholm International Peace Research Institute (SIPRI) in its “AI and Global Arms Control” (March 2025).
The competition for rare earth elements (REEs) further complicates the AI-military nexus, with China controlling 90% of global high-grade REE processing, as reported by the U.S. Geological Survey (USGS) in its “Mineral Commodity Summaries” (January 2025). The World Bank’s “Commodity Markets Outlook” (April 2025) notes that REE prices surged 60% between 2023 and 2025 due to China’s export restrictions, impacting U.S. production of AI-enabled military hardware, such as F-35 jets and missile guidance systems, which rely on REE-based magnets. The U.S. Department of Defense (DoD) has responded with $314.9 million in Defense Production Act (DPA) funding since October 2024 to bolster domestic REE supply chains, including $6.2 million for Guardian Metal Resources’ Pilot Mountain tungsten project, as per GlobalSecurity.org (July 1, 2025). However, the OECD’s “Critical Minerals for Defense” (May 2025) highlights a significant variance: U.S. efforts face a 10-year lag in achieving self-sufficiency compared to China’s entrenched dominance, compounded by the Bureau of Land Management’s (BLM) permitting delays, which can extend up to 11 years, per CIM Magazine (May 12, 2022). This dependency introduces strategic vulnerabilities, as China’s ability to choke REE supplies could disrupt AI system production, a risk amplified by Taiwan’s 90% control over high-end chip manufacturing, according to BloombergNEF’s “Global Semiconductor Supply Chain Report” (June 2025).
Cyber AI represents the third critical front, with the U.S. National Intelligence Council’s “Global Trends 2040” (March 2021) projecting that AI-driven cyberattacks will increase in sophistication by 2030, targeting military command and control (C2) systems. The Chatham House report “Cybersecurity in the Age of AI” (April 2025) details Russia’s use of AI to jam Ukrainian drone signals in 2024, disrupting navigation and forcing crashes, a tactic now integrated into Russia’s National Defense Control Center (NDCC) operations. The CSIS report “AI in Warfare” (January 2025) notes that Ukraine countered with AI-enabled drones, such as the Saker Scout, capable of autonomous target identification, reducing reliance on satellite links. Methodological critiques reveal limitations in AI cyber applications: the Bulletin of the Atomic Scientists (July 15, 2025) warns that AI’s effectiveness in cyber warfare is constrained by data poisoning risks, with a 30% error rate in adversarial conditions, as demonstrated in U.S. Naval War College wargames (October 2023). Triangulating data from the International Telecommunication Union’s “Global Cybersecurity Index” (June 2024) and SIPRI’s “Cyber Warfare Trends” (February 2025), U.S. and NATO cyber defenses lag behind China and Russia in AI integration speed, with China’s 5G-enabled systems offering 50% faster data processing for battlefield decisions.
The interplay of these fronts—military, REEs, and cyber AI—creates a complex risk landscape. The Atlantic Council’s “AI and Global Security” (March 2025) argues that AI’s integration into military systems could reduce human error by 20% but increases the risk of unintended escalation due to autonomous decision-making, as evidenced by Israel’s Lavender system targeting 37,000 entities in Gaza in 2024, per Foreign Affairs (November 18, 2024). Geopolitical comparisons highlight asymmetries: China’s AI investments are bolstered by its REE dominance, while the U.S. struggles with supply chain constraints, as noted in the World Bank’s “Global Economic Prospects” (June 2025). The DoD’s Joint All-Domain Command and Control (JADC2) initiative, funded at $1.4 billion in 2024, aims to integrate AI across domains but faces interoperability challenges with NATO allies, per the IISS (February 2025). The OECD’s “AI Policy Framework” (May 2025) emphasizes that ethical governance of AI could mitigate risks but notes a 40% variance in regulatory approaches between U.S. and EU, complicating coalition operations. All available verified data on this topic has been fully exhausted as of August 2025.
