Governments say they want diversified critical minerals supply chains. Yet many regulatory systems still require a decade or more to move new mines from discovery to production. Getting a processing plant going is similarly protracted.
Unless permitting systems deliver shorter and predictable timelines while maintaining high environmental and cultural safeguards, supply-chain diversification will remain slower than strategic demand requires.
The energy transition and advanced defence capability are underpinned by materials such as lithium, nickel, cobalt and rare-earth elements. Supply chains for many of these materials remain highly concentrated, particularly in refining and chemical processing. Governments seeking diversification require both new resources and regulatory systems capable of delivering projects at speed.
Demand growth reinforces the urgency. The International Energy Agency (IEA) estimates that demand for lithium from clean-energy technologies could grow by more than 40 times between 2020 and 2040 in scenarios aligned with net-zero pathways. Demand for nickel, cobalt and rare-earth elements will also increase sharply. Yet mineral development timelines remain long. Studies by the IEA and S&P Global show that the average time from discovery to first production is 15 to 20 years. Geological appraisal, environmental baseline studies, engineering design, infrastructure development and financing all affect this. Regulatory sequencing nevertheless plays a decisive role in determining whether projects move forward.
Investment economics magnifies the problem. Large mining developments frequently operate in volatile commodity markets and require capital investments measured in billions of dollars. Development delays increase financing risk, raise the cost of capital and reduce projects’ net present value. Even modest delays can have significant financial consequences. Fraser Institute surveys of mining investors consistently identify regulatory uncertainty as one of the most important factors influencing exploration investment decisions.
Australia illustrates both the challenge and the opportunity. Major resource projects typically require approvals across various state and federal environmental regimes alongside heritage processes, water licensing and infrastructure planning. Each regulatory step serves a legitimate purpose. Sequential decision-making and duplication across agencies, however, can extend development timelines and create uncertainty for proponents. Canada faces similar pressures as new mining proposals emerge to meet growing critical-mineral demand.
Australia’s Critical Minerals Strategy highlights environmental, social and governance performance as a strength in global markets. Canada’s Critical Minerals Strategy likewise positions responsible mining as central to its international supply proposition. Strong standards remain essential. The strategic challenge lies in delivering those standards with greater regulatory predictability.
Australia and Canada also share structural advantages that make collaboration particularly attractive. Both operate stable legal systems, maintain internationally active mining sectors and host globally significant mineral reserves. Companies headquartered in both countries operate projects across continents, and investors recognise their regulatory frameworks as among the most credible. Cooperation could demonstrate how high standards and predictable timelines reinforce each other.
Permitting reform should focus on three practical areas that improve regulatory efficiency without weakening safeguards.
Governments should harmonise environmental and heritage assessments. Parallel reviews across agencies frequently examine similar environmental evidence. Coordinated assessment frameworks can allow regulators to review projects concurrently rather than sequentially. Canada’s integrated impact-assessment system and joint review mechanisms demonstrate how regulators can coordinate scrutiny while maintaining rigorous standards.
Governments should embed Indigenous partnerships early in project design. Early engagement enables Traditional Owners and project developers to identify cultural and environmental sensitivities before project plans are finalised. Indigenous Land Use Agreements in Australia provide a structured mechanism for negotiating land use and benefit-sharing arrangements. Early partnership strengthens social licence and reduces the likelihood of disputes that can delay projects later in development.
Regulators should pursue digital interoperability across approval systems. Mining projects generate extensive environmental modelling, geological data and monitoring information. Digital regulatory platforms allow agencies to review shared datasets simultaneously. Western Australia’s Environment Online system and Canada’s Impact Assessment Registry demonstrate how digital platforms can improve transparency, reduce administrative duplication and shorten decision timelines.
Financing gaps, infrastructure limitations and downstream processing capacity also shape critical-mineral project outcomes. New mines often require rail, port and energy infrastructure before production begins. Projects should also secure long-term offtake agreements to attract investment. Diversification requires coordinated development across exploration, mining, processing and manufacturing supply chains.
Permitting nonetheless remains a decisive, government-controlled lever. When approval timelines become uncertain, investors discount project value or direct capital elsewhere. Predictability in regulatory decision-making is therefore a strategic asset.
Countries seeking to diversify supply chains should test cross-jurisdictional trusted project pathways for critical-minerals facilities. Participating countries should align environmental reporting standards; recognise equivalent environmental, social and governance certification frameworks; and allow regulatory data submitted in one jurisdiction to support assessments in another. Projects meeting agreed environmental and Indigenous partnership benchmarks could then move through national approval systems with greater predictability.
Australia and Canada are well placed to lead that work. They already promote responsible mining as part of their offers to global markets. Joint leadership on regulatory cooperation could demonstrate that strong safeguards and efficient approvals can coexist in advanced regulatory systems.
Countries that combine credible environmental safeguards with reliable approval timelines will attract capital, bring responsible projects online faster and strengthen economic security. Speed without shortcuts will determine which economies succeed in building resilient critical-minerals supply chains.
