G7 Critical Minerals Investment: Securing Supply Chains by 2025

What Are Critical Minerals and Why Is the G7 Concerned?

The G7 (United States, Canada, Japan, Germany, United Kingdom, France, Italy, and the European Union) has recently highlighted critical minerals as a vital component of national security and economic resilience. According to a draft document prepared for the upcoming Kananaskis meeting in Canada, the group is focusing on securing supply chains for these essential materials amid growing global concerns about G7 and critical minerals investment.

"We share common concerns about national and economic security, and both rely on resilient supply chains for critical minerals based on market rules," states the G7 draft document.

Critical minerals include rare earth elements, gallium, germanium, graphite, and antimony—materials that, while often required in relatively small quantities, play outsized roles in modern manufacturing, defense systems, and renewable energy technologies. Their strategic importance has grown exponentially as nations race toward green energy transitions and digital transformation.

The Strategic Importance of Critical Minerals

Critical minerals serve as fundamental building blocks for today's most important technologies. Rare earth elements like neodymium and dysprosium are essential for creating powerful permanent magnets used in electric vehicle motors, wind turbines, and military equipment. Gallium and germanium are crucial semiconductor components enabling advanced electronics and telecommunications. Graphite serves as a key material in lithium-ion batteries, while strategic antimony financing has become increasingly important for flame retardants, batteries, and electronics.

The G7's concern stems from a troubling reality: the supply chains for these minerals are highly concentrated, with processing capabilities particularly centralized in specific regions. This concentration creates vulnerability to supply disruptions, whether from natural disasters, political tensions, or deliberate market manipulation.

"Non-market policies and practices in the critical minerals sector threaten our ability to access critical minerals, including rare earth elements needed for magnets, which are of extreme importance to industrial production," the draft document warns.

Current Supply Chain Vulnerabilities

The concern around critical minerals didn't emerge overnight. According to the G7 draft, "Since the US initiated the tariff war, Western countries have been increasingly concerned about the secure supply of critical minerals" including the five key minerals mentioned above. This heightened awareness reflects growing recognition of several interconnected vulnerabilities:

• Geographic concentration: Both mining and processing capacities are heavily concentrated in a small number of countries, creating potential choke points in global supply chains.

• Market manipulation risks: The draft explicitly cites "market manipulation" as a threat to stable supply, referring to practices where dominant suppliers can artificially restrict availability or drive price volatility.

• Regulatory bottlenecks: Western nations face "complex permitting and approval processes" that can delay new mining projects for years, sometimes decades, hampering their ability to develop domestic supplies.

• Non-market practices: The G7 document specifically mentions that "non-market policies and practices" threaten access to these essential minerals, suggesting concerns about state-directed economic activities that distort global markets.

These vulnerabilities have transformed what might otherwise be straightforward commodity markets into matters of national security and economic resilience. With renewable energy technologies requiring significantly more minerals than their conventional counterparts, securing stable supplies has become increasingly urgent for G7 nations committed to climate goals.

How Is the G7 Planning to Address Critical Mineral Challenges?

The G7's approach to addressing critical mineral supply vulnerabilities centers on a comprehensive action plan that prioritizes diversification, investment acceleration, and market-based solutions. Based on the draft document being prepared for the Kananaskis meeting, the strategy represents a significant shift in how these advanced economies view mineral resources—elevating them from mere commodities to strategic assets requiring coordinated policy attention.

The Proposed G7 Action Plan

At the heart of the G7's strategy is a recognition that business-as-usual approaches are insufficient for addressing the scale and urgency of critical mineral supply challenges. The draft document emphasizes the need to "expand investment to secure future supply chains" through a multilateral effort that combines policy coordination, financial incentives, and regulatory improvements.

Key objectives outlined in the document include:

• Diversifying supply sources to reduce external dependencies
• Accelerating "large-scale investment as soon as possible" in mining and processing
• Streamlining mining permitting insights and approval processes to enable faster project development
• Countering market manipulation and reducing price volatility
• Promoting responsible investment within G7 countries and globally

"There is an urgent need to expand investment to secure future supply chains and ensure that mining, beneficiation, and smelting projects address numerous obstacles," the draft states, highlighting the comprehensive scope of the initiative.

Rather than attempting to completely reshoring critical mineral supply chains—an unrealistic goal given the geographic distribution of mineral deposits—the G7 approach focuses on building resilience through diversification and strategic partnerships. This market-based approach aims to counter non-market practices that have distorted global mineral markets.

Large-Scale Investment Acceleration Strategy

The cornerstone of the G7 initiative is its push to dramatically accelerate investment in critical mineral projects. The draft document calls for focusing on three key areas of the supply chain:

1. Mining operations: Expanding extraction capacity for primary mineral resources
2. Beneficiation facilities: Increasing capabilities to concentrate and prepare minerals for processing
3. Smelting and refining: Developing advanced processing infrastructure to produce high-purity materials

To finance this ambitious expansion, the G7 is looking beyond traditional government funding. The draft encourages "multilateral development banks and private lenders to provide more funding for eligible critical mineral projects, including innovative financing." This approach recognizes that the capital requirements for developing new mineral projects often exceed what government budgets alone can provide.

The initiative also directly addresses the obstacles that have historically slowed critical mineral development in G7 countries:

• Permitting reform: Streamlining "complex permitting and approval processes" while maintaining environmental standards
• Market stability: Countering "market manipulation and price fluctuations" that create investment uncertainty
• Financial innovation: Developing new financing mechanisms to address the unique challenges of mineral projects

By tackling these barriers simultaneously, the G7 hopes to create conditions where private capital flows more readily into critical mineral projects, accelerating development timelines and expanding global supply.

Which Critical Minerals Are Prioritized in the G7 Initiative?

The G7 draft document specifically names five mineral categories as priorities for its investment and supply chain security initiative. Each plays a crucial role in advanced technologies and the green energy transition, with applications spanning from defense systems to renewable energy infrastructure.

High-Priority Critical Minerals

Rare Earth Elements (REEs) stand at the forefront of the G7's concerns. These 17 elements, including neodymium, praseodymium, dysprosium, and terbium, are essential for creating the powerful permanent magnets used in electric vehicles, wind turbines, and defense applications. The draft document explicitly highlights "rare earth elements needed for magnets, which are of extreme importance to industrial production."

The concentration of rare earth processing capabilities has created particular vulnerability in global supply chains. While mining occurs in various countries, the sophisticated metallurgical processes required to separate and purify individual elements remain heavily concentrated, creating a potential bottleneck for industries requiring these materials.

Gallium and germanium represent another category of concern. These semiconductor materials enable advanced electronics, including those used in 5G telecommunications, LED lighting, solar cells, and radar systems. Their applications in both civilian and military technologies make them strategically significant. Gallium is typically recovered as a byproduct of aluminum production, while germanium is often extracted during zinc processing, making their supply chains particularly complex.

Graphite has gained prominence primarily due to its essential role in lithium-ion batteries. As the primary material for battery anodes, graphite demand is projected to surge with electric vehicle adoption. Both natural and synthetic graphite face supply challenges—natural graphite mining is concentrated in a few countries, while synthetic graphite production is energy-intensive and often relies on coal-based processes that conflict with decarbonization goals.

Antimony, though less frequently discussed in public discourse, remains critical for numerous applications including flame retardants, lead-acid batteries, and military equipment. Its inclusion in the G7 priority list reflects concerns about highly concentrated production and limited substitutability in key applications.

Supply-Demand Dynamics and Future Projections

The G7's focus on these specific minerals reflects underlying supply-demand imbalances that threaten economic and security interests. While the draft document doesn't provide quantitative projections, its emphasis on "urgent need to expand investment" signals recognition of looming supply gaps as demand accelerates.

Several factors are reshaping critical mineral markets:

• Energy transition acceleration: Clean energy technologies generally require more minerals than their fossil fuel counterparts. Electric vehicles use approximately six times the mineral inputs of conventional cars, while wind power facilities need nine times more mineral resources than gas-fired plants.

• Defense applications: Advanced military systems increasingly rely on specialized materials, including rare earths for precision-guided munitions and gallium for radar systems.

• Digital infrastructure: The expansion of telecommunications networks, data centers, and semiconductor manufacturing is driving demand for specialized mineral inputs.

• Processing bottlenecks: Even where mining capacity exists, limited refining and processing capabilities create vulnerabilities in the supply chain.

The G7's initiative aims to address these dynamics by expanding capacity throughout the supply chain—from mining through processing to end-use manufacturing—while ensuring that new development follows market-based approaches and responsible practices.

How Will This Initiative Impact Global Mining and Processing?

The G7's critical minerals strategy represents a significant shift in how advanced economies approach resource development. By prioritizing investment acceleration and supply chain diversification, the initiative could reshape global mining and processing landscapes over the coming decades.

Investment Opportunities in G7 Countries

Within G7 nations themselves, the initiative creates substantial opportunities for developing new mining and processing capabilities. Countries like Canada and the United States possess significant geological reserves of many critical minerals but have historically faced challenges in developing these resources due to regulatory complexities, capital constraints, and market uncertainties.

The G7 draft document directly addresses these barriers, noting the need to overcome "complex permitting and approval processes, market manipulation, and price fluctuations." By streamlining regulatory pathways while maintaining environmental standards, G7 countries aim to unlock their domestic mineral potential.

Potential developments could include:

• Mining project acceleration: New and expanded mining operations targeting graphite, rare earths, and other priority minerals
• Processing infrastructure: Development of specialized facilities for mineral beneficiation, separation, and refining
• Technology innovation: Investment in advanced extraction and processing technologies to improve efficiency and reduce environmental impacts
• Workforce development: Training programs to address the specialized skills needed for critical mineral operations

The initiative also recognizes that responsible investment must balance economic and security objectives with environmental and social considerations. While the document emphasizes accelerating development, it also refers to "responsible investment," suggesting that environmental, social, and governance (ESG) standards will remain important factors in project approval and financing.

Global Partnerships Beyond G7

The G7's approach extends beyond its member nations, acknowledging that truly resilient supply chains require global cooperation. The draft document mentions expanding "responsible investment in critical mineral projects within the G7 and globally," indicating an outward-looking strategy that includes partnerships with resource-rich developing nations.

This global dimension could manifest through:

• Strategic partnerships with countries possessing significant mineral resources but lacking capital or technical capacity for development
• Technical assistance programs to help partner nations develop extraction and processing capabilities
• Trade agreements that secure mineral supply while promoting responsible production practices
• Infrastructure development to enable efficient transport of materials from extraction to processing facilities

By fostering these international connections, the G7 aims to create more diversified and resilient supply networks that are less vulnerable to disruption or manipulation by any single actor. This approach recognizes that even with increased domestic production, G7 nations will remain interconnected with global mineral markets.

The initiative's emphasis on market-based approaches also suggests a preference for commercial partnerships over direct government control of mineral resources, distinguishing it from more state-centric resource development models.

What Are the Geopolitical Implications of the G7 Critical Minerals Strategy?

The G7's push to reshape critical mineral supply chains carries significant geopolitical implications, potentially altering trade relationships, industrial competitiveness, and strategic alignments. By explicitly addressing "non-market policies and practices" that threaten mineral access, the initiative signals a shift toward critical minerals energy security considerations in resource policy.

Shifting Global Supply Chain Dynamics

At its core, the G7 strategy aims to reduce what the draft document calls "external dependencies" on concentrated supply sources. This language reflects growing concerns about supply chain vulnerabilities that became particularly apparent during recent global disruptions, including the COVID-19 pandemic and various trade tensions.

The initiative could reshape global mineral markets in several ways:

• Diversification of supply sources: Development of new mining and processing operations across multiple regions, reducing the market power of current dominant suppliers
• Creation of "friendly" supply networks: Preferential trading arrangements among G7 members and aligned partners to ensure secure access to critical materials
• Technology transfer: Sharing of extraction and processing expertise to help allied nations develop their mineral resources
• Standards alignment: Harmonization of environmental and social standards to create a more level playing field for responsible producers

This reorientation represents a significant departure from the globalization model that dominated recent decades, which prioritized efficiency and cost minimization over supply security and resilience. The G7's approach instead emphasizes the strategic importance of these materials, even if developing more diversified supply chains entails higher costs in the short term.

Economic Security Considerations

The draft document explicitly frames critical minerals as components of "national and economic security," elevating them from purely commercial concerns to matters of strategic importance. This framing enables policy approaches that might not be justified on strictly economic grounds but are deemed necessary for long-term security.

Key security considerations include:

• Industrial policy coordination: Alignment of domestic manufacturing strategies with mineral supply security to support critical industries
• Technology leadership: Ensuring access to materials needed for innovation in strategic sectors like renewable energy, defense, and advanced computing
• Resilience to coercion: Reducing vulnerability to supply disruptions that could be used as leverage in international disputes
• Strategic autonomy: Maintaining the capability to produce essential technologies regardless of international tensions

The G7's approach balances competition and cooperation—pursuing greater self-sufficiency while simultaneously recognizing the need for international partnerships. This nuanced position reflects the reality that complete mineral independence is neither geologically possible nor economically rational for most countries.

By coordinating their approaches to critical mineral supply chains, G7 nations aim to strengthen their collective bargaining position and create more favorable conditions for their industries that depend on these materials. This coordination represents a form of economic statecraft that uses market mechanisms to achieve strategic objectives.

What Challenges Must Be Overcome for Successful Implementation?

Despite its ambitious scope, the G7 critical minerals initiative faces substantial implementation challenges. Transforming global supply chains requires overcoming entrenched regulatory barriers, financial constraints, and technical limitations that have historically slowed critical mineral development in G7 countries.

Regulatory and Permitting Hurdles

The draft document explicitly identifies "complex permitting and approval processes" as obstacles to critical mineral project development. This recognition reflects the reality that new mining projects in G7 countries often face approval timelines measured in years or even decades, creating significant barriers to investment.

Key regulatory challenges include:

• Multi-layered approval processes: Projects typically require permits from local, regional, and national authorities, creating complex procedural requirements
• Environmental assessment timelines: Thorough environmental impact studies are essential but can extend project timelines substantially
• Public consultation requirements: Engaging communities and addressing concerns is necessary but time-consuming
• Legal challenges: Even after receiving approvals, projects often face litigation that further delays development

The G7 initiative aims to streamline these processes without compromising environmental standards or community engagement. This balancing act represents one of the most difficult aspects of implementation, requiring careful policy design and potentially legislative changes in member countries.

Financing and Investment Barriers

Developing new critical mineral projects requires substantial capital investment, often with extended payback periods and significant market risks. The draft document acknowledges this challenge by encouraging "multilateral development banks and private lenders to provide more funding for eligible critical mineral projects, including innovative financing."

Financial obstacles include:

• High upfront capital requirements: Establishing mines and processing facilities typically costs hundreds of millions or billions of dollars
• Extended development timelines: The period from discovery to production can stretch beyond a decade, delaying returns on investment
• Market volatility: Critical mineral prices often experience significant fluctuations, creating uncertainty for investors
• Competition for capital: Mining projects compete with other sectors for investment, often at a disadvantage due to perceived ESG risks

The G7's emphasis on "innovative financing" suggests recognition that traditional funding models may be insufficient. Potential approaches could include public-private partnerships, government loan guarantees, offtake agreements to secure future sales, and blended finance structures that combine public and private capital.

Technical and Infrastructure Constraints

Beyond regulatory and financial challenges, critical mineral development faces substantial technical barriers. Many G7 countries have limited recent experience with certain types of mineral processing, creating gaps in both infrastructure and expertise.

Technical constraints include:

• Processing know-how: Specialized metallurgical knowledge required for separating and purifying many critical minerals
• Infrastructure requirements: Needs for reliable power, water, and transportation connections to support operations
• Workforce capabilities: Shortage of skilled personnel with experience in specialized mineral processing
• Research gaps: Need for improved extraction and processing technologies to enhance efficiency and reduce environmental impacts

Addressing these technical challenges requires not only investment in physical infrastructure but also in human capital and research capacity. The G7 initiative's success will depend partly on its ability to rebuild technical capabilities that have atrophied in many member countries as processing moved overseas.

These multilayered challenges explain why the draft document emphasizes the "urgent need to expand investment" and calls for a comprehensive approach that addresses regulatory, financial, and technical barriers
