The global race to secure critical mineral supplies has become one of the defining geopolitical and economic challenges of the decade. The G7 nations have moved beyond policy discussions and are now pursuing concrete strategies to reduce their reliance on China for essential raw materials used in clean energy, advanced manufacturing, defense, and high-tech industries.
During the latest G7 summit, member states reaffirmed their commitment to diversify supply chains by ensuring that no single non-G7 country accounts for more than 60% of rare earth elements and permanent magnet supplies by 2030, with an even more ambitious target of 50% in the years that follow. While the strategy is primarily aimed at reducing China’s dominance, achieving these goals will require enormous investments across the entire mineral value chain.
Iran Emerges as an Unexpected Strategic Player
As the G7 searches for alternative sources of critical raw materials, Iran has unexpectedly entered the conversation. Long viewed primarily through the lens of sanctions and geopolitical tensions, the country is now attracting renewed attention because of its vast reserves of copper, zinc, aluminum, and other industrial minerals.
Iran possesses one of the world’s largest untapped mineral portfolios, positioning it as a potentially important supplier if international investment conditions improve. This creates a strategic dilemma for Western governments seeking diversified supply chains while remaining cautious about political and financial risks.
Copper Resources Could Transform Global Supply Chains
Among Iran’s most valuable assets is its enormous copper industry. Geological estimates indicate that the country holds approximately 2.6 billion metric tonnes of identified copper resources, representing roughly 5% of global known reserves.
Major mining operations, including the Sarcheshmeh Copper Complex, together with the Sungun and Miduk mines, make Iran one of the Middle East’s largest copper producers.
The importance of copper continues to grow as the global economy accelerates its transition toward electrification. Every electric vehicle, renewable energy installation, transmission line, data center, and smart grid requires significant quantities of copper, making the metal one of the most strategic resources of the energy transition.
Mining Alone Is Not Enough
While discovering new mineral deposits is important, mining represents only one part of the supply chain.
The greatest challenge facing Western economies lies in processing, refining, metallurgy, industrial chemistry, and advanced manufacturing. China continues to dominate these midstream industries, giving it a commanding position in the production of rare earth materials and permanent magnets. Without substantial investments in refining capacity and downstream manufacturing, simply opening new mines will not significantly reduce dependence on Chinese supply chains.
Iran Could Strengthen Industrial Mineral Markets
Although Iran is not expected to become a major producer of rare earth elements, it could play a significant role in expanding supplies of copper, zinc, aluminum, and other industrial metals that are essential for modern infrastructure.
These materials support the construction of:
- Electricity transmission grids
- Renewable energy facilities
- Electric vehicle infrastructure
- Industrial manufacturing plants
- Transportation networks
Iran’s geographic location also provides strategic access between Asia, Europe, and the Middle East, potentially making it an important logistics and processing hub.
Political Risk Remains the Biggest Obstacle
Despite its enormous geological potential, Iran continues to present significant challenges for international investors.
Mining projects typically require investment horizons measured in decades, while diplomatic agreements and sanctions policies can change within months. Investors remain cautious after previous experiences where sanctions were eased before being reintroduced only a few years later.
As a result, financing large mining projects requires much more than valuable mineral deposits. Investors need:
- Stable legal frameworks
- Transparent ownership structures
- Reliable payment mechanisms
- Political risk insurance
- Long-term supply agreements
- International regulatory certainty
Without these safeguards, even world-class mineral assets remain difficult to finance.
Regional Stability Also Influences Mineral Markets
Iran’s strategic importance extends beyond its mineral reserves.
The Strait of Hormuz, one of the world’s most important shipping corridors, also plays a vital role in supplying chemicals required for mineral processing. Materials such as sulfur and sulfuric acid, which are essential for processing copper, lithium, nickel, and rare earth elements, have experienced sharp price increases during periods of regional instability. Higher chemical costs directly impact the economics of mineral refining worldwide, demonstrating that critical mineral security depends on stable trade routes as much as mining capacity.
The Economics of Supply Chain Diversification
Another major challenge for the G7 is financial.
Developing new mining and refining capacity outside China often involves:
- Higher production costs
- Long permitting processes
- Large upfront capital investments
- Complex environmental regulations
Without government support or financial mechanisms capable of reducing investment risk, many Western mining projects struggle to compete against China’s highly integrated industrial ecosystem.
Will Western Investors Participate?
Iran presents an interesting paradox.
Its mineral resources could offer lower production costs than many Western projects, yet investors must also account for:
- Sanctions exposure
- Currency volatility
- Political uncertainty
- Corruption risks
- Payment restrictions
- Reputational concerns
These factors make Iran attractive from a geological perspective but considerably more complex from an investment standpoint.
China Could Benefit if the West Hesitates
If Western companies remain unwilling to invest, Iran’s resources are unlikely to remain undeveloped. Instead, Chinese companies and regional investors could expand their presence, strengthening China’s influence over global mineral supply chains rather than weakening it.
Such an outcome would directly contradict the G7’s long-term objective of diversifying strategic mineral production.
Europe Faces Strict ESG Requirements
For European manufacturers, reliable access to copper, aluminum, nickel, lithium, and other critical minerals is essential for the production of renewable energy systems, electric vehicles, defense equipment, and advanced industrial technologies.
Future imports from Iran would also need to satisfy increasingly strict ESG (Environmental, Social and Governance) standards.
European buyers are expected to require:
- Verified carbon emissions reporting
- Transparent mining operations
- Responsible tailings management
- Labor protection standards
- Supply chain traceability
- Environmental compliance documentation
Only producers capable of meeting these requirements are likely to gain broad access to European markets.
A New Test for the G7’s Mineral Strategy
Iran ultimately represents one of the most important tests of the G7’s critical minerals strategy. Reducing dependence on China requires more than ambitious targets. It demands bankable mining projects, modern processing facilities, resilient transportation networks, secure financing, and long-term geopolitical stability.
Iran possesses the geological resources needed to become a significant contributor to global copper and industrial mineral markets. Whether those resources ultimately strengthen Western supply chains or deepen the influence of competing global powers will depend on future diplomatic developments, investment decisions, and international cooperation.
The next phase of the global minerals race will not be decided solely in traditional mining jurisdictions. It will also be shaped in politically complex regions where abundant resources, limited investment, and evolving geopolitical realities intersect.
