Resource Nationalism Reshapes the Critical Minerals Landscape: Australian Mining Faces New Rules

Resource nationalism is expanding beyond traditional disputes over taxes and royalties to include export controls, production quotas, localization requirements for processing, and direct government intervention, forcing investors in critical minerals like lithium and rare earths to reassess risks and strategies. According to a recent analysis by international law firm Gibson Dunn, this shift is turning critical minerals from a traditional mining competition into a geopolitical game. For Australia—a major global supplier of lithium, rare earths, and nickel—this trend presents both opportunities from supply chain diversification and increased complexity in investment and operations.

Critical Minerals: From Commercial Resources to Strategic Assets

Governments are increasingly viewing critical minerals as strategic assets linked to economic competitiveness, technological leadership, and national security. China expanded export controls on rare earths in October 2025, and although they were suspended a month later due to an agreement with the U.S., the framework remains available for activation at any time, highlighting its willingness to use its dominance in rare earth processing as a bargaining chip. The Democratic Republic of the Congo (DRC) implemented a cobalt export ban in February 2025, later converting it into production quotas, directly impacting the global battery supply chain. Indonesia's nickel export ban successfully attracted hundreds of billions of dollars in downstream investment, becoming a typical case of resource nationalism. Vietnam has tightened controls on rare earth mining and banned raw material exports, while Chile continues to promote a state-led lithium development model.

These measures are widening the divide between producer and consumer countries: producers seek to extract greater value from resources, while consumers attempt to secure stable supplies for the energy transition, defense, and advanced manufacturing. The U.S. has elevated critical minerals to a national security priority through strategic reserves and allied supply chain initiatives; the EU's Critical Raw Materials Act aims to reduce external dependence and enhance domestic processing capabilities.

Impact on Australian Mining

Australia is one of the world's largest lithium producers and a significant source of critical minerals such as rare earths, nickel, and cobalt. The wave of resource nationalism affects Australian mining on multiple levels:

1. Increased competition in export markets: Indonesia's nickel export ban and the DRC's cobalt production quotas have weakened traditional supply channels, prompting Australian nickel and cobalt producers to seek new markets. However, global smelting and processing capacity is highly concentrated, especially China's control over lithium and rare earth processing (accounting for about 60% of global lithium chemical production capacity and about 90% of rare earth separation capacity), meaning Australian mining companies still rely on Chinese processing facilities, facing geopolitical risks.

2. Rising investment uncertainty: Resource nationalism measures—such as export restrictions, license changes, and processing requirements—can alter project economics and trigger disputes under bilateral investment treaties. Gibson Dunn points out that stability clauses in many mining and infrastructure agreements could be overturned by governments on grounds of national security or public interest. Australian mining companies operating overseas (e.g., in Chile, the DRC) are facing such risks.3. Opportunities for Supply Chain Diversification: Consumer countries such as the United States and the European Union are actively promoting cooperation with "friendly" supply countries like Australia to establish supply chains that replace China. For example, the U.S. has provided financial support to Australian critical mineral projects through the Defense Production Act, while the EU has listed Australia as a strategic partner for critical raw materials. This opens up new markets for Australian mining companies, but also requires them to meet stricter ESG standards and compliance requirements.

4. Pressure to Build Local Processing Capacity: The Australian government has introduced several policies to encourage domestic processing of minerals such as lithium and rare earths, including the "Critical Minerals Processing Centre" plan and funding under the "Modern Manufacturing Initiative." However, high energy costs, labor shortages, and lengthy approval processes constrain progress. The wave of resource nationalism reinforces the strategic necessity of local processing, but companies must still balance economic feasibility.

Corporate Response Strategies

Gibson Dunn advises companies to take action before disputes arise: review ownership structures, update contracts to address resource nationalism risks, and assess political risk insurance. Additionally, reassess processing locations and supply chain design—geography may become as important as geology. For Australian mining companies, this means:

• Strengthening coordination with governments and trading partners to ensure diversified export channels.
• Investing in compliance and legal capabilities to navigate multiple countries' export controls, sanctions, and foreign investment review regimes.
• Exploring long-term offtake agreements with downstream manufacturers to lock in demand and share risks.
• Participating in international initiatives such as the Minerals Security Partnership (MSP) to promote transparent and sustainable critical mineral supply chains.

Long-Term Trends: The Integration of Legal and Business Strategies

This wave of resource nationalism surpasses previous ones in both scope and complexity: export controls, processing requirements, investment restrictions, and supply chain alliances create a far more complex landscape than traditional tax increases or royalty disputes. For Australian companies, legal strategy is becoming inseparable from business strategy. The winners will be those entities that can find balance in geopolitical games and adapt to deep government involvement in the resource race.

Over the next 3-10 years, the geopolitical nature of critical minerals will continue to intensify. Australia, as a resource-rich and well-governed supply country, is well-positioned to occupy a core role in diversified supply chains, but only if it can overcome local processing bottlenecks, maintain cost competitiveness, and properly manage political risks in overseas operations.

Conclusion

Resource nationalism is rewriting the investment rules for critical minerals. For Australia, this trend is both a challenge and an opportunity to reshape its position in the global mineral supply chain. Companies must integrate legal risk prevention, supply chain resilience, and geopolitical analysis into their core strategies. Government policy support and industry collaboration will determine whether Australia can secure an advantageous position in this resource game.
