Mining Mindset: Guy Winter - Tariffs, Critical Minerals, and Resource Wars’ Legal Crossroads

The global energy and mining sectors are now defined by the energy trilemma - the need to simultaneously deliver sustainability, affordability, and security of supply. Over the past two decades, the renewables revolution has been the biggest upheaval to global energy use since the industrial revolution, while the oil and gas sector has adapted through innovations like fracking and frontier exploration.

Technology companies have become major players in what was once an old economy sector. Companies like K-MINE demonstrate how technology can disrupt traditional mining operations and deliver more efficient ways of working. Artificial intelligence, in particular, has brought entirely new players into the energy and mining space, and today's mining executives look very different from those of 25 years ago.

The regulatory landscape now reflects these changes. Where growth was once driven entirely by fossil fuels, the new paradigm demands that mining and energy companies balance environmental sustainability with economic viability and reliable supply. Carbon border mechanisms, the EU battery regulation, and resource nationalism are all adding layers of complexity. At the same time, a competing tension has emerged between US-style deregulation and Europe's continuing focus on environmental standards.

The current US administration's tariff policy has created significant implications for global mining and energy markets. The US government is investigating the impact of critical mineral imports and is also examining the copper market, with the likelihood of new tariffs designed to incentivize domestic project development.

Canada, as a major exporter of energy and raw materials to the United States, is looking to diversify its base. Projects focused on LNG export and hydrocarbon pipelines to the east coast of Canada are expected to be expedited. At the same time, critical minerals have become a central part of the geopolitical equation.

A key recent development involves rare earths. China imposed export controls on certain heavy rare earths in retaliation for US tariffs, and the United States currently has no processing capability for heavy rare earths. In response, MP Materials - operator of the Mountain Pass mine in California - announced a joint venture with Ma'aden in Saudi Arabia to build rare earth processing capacity outside of China. This represents a radical geopolitical shift as the US looks to develop minerals processing capacity independent of Chinese supply chains.

The result is a new era of competition for resources. Each major geopolitical block is looking to proactively secure its own access to vital minerals. The US approach relies on tariffs to drive domestic capacity and relaxing ESG rules for mining projects. The EU takes a different path, using ESG standards as a barrier to entry and setting high sustainability requirements for battery manufacturing materials. China, meanwhile, has used critical mineral export controls as leverage in its trade war with the United States.

The tariff environment has forced mining and energy companies worldwide to review their contracts for the supply of energy and critical materials. The key legal question is: what happens to contractual obligations when a sudden tariff doubles the cost of material to the importer? Can the contract be terminated? Does force majeure apply?

In M&A transactions, companies must assess whether deals already agreed should still proceed if the economics are hugely distorted by tariffs or export controls. The uncertainty has also raised serious questions about how long companies are willing to commit to contracts. Long-term fixed price contracts have become particularly risky in a trade war environment between two of the world's biggest economic blocks.

Some companies have already terminated supply arrangements entirely. MP Materials announced it would stop exporting material to be refined in China, recognizing that US taxpayer subsidies should not support mining of rare earths that ultimately supply Chinese processing plants.

For contracts that remain in force, companies are building more flexibility to enable price renegotiation in response to unforeseen tariff impacts. Historically, force majeure clauses excluded purely economic effects like cost increases. But in current conditions, new clause structures may be needed - provisions that allow renegotiation or supply suspension when significant tariffs are imposed.

Market distortion is another factor. The 2022 nickel crisis, when LME prices spiked by several hundred percent in days and the market had to be shut down, led to high-profile litigation and underscored the risks of relying on spot markets in volatile conditions. Contracts for critical material supply now need to account for these scenarios.

A common misconception in the early days of the energy transition was that fossil fuels would simply be replaced by renewable sources like solar and wind. The reality is more complex - the energy transition depends on the minerals that go into new energy infrastructure.

Direct-drive wind turbines require powerful permanent magnets made from rare earths. Electric vehicle batteries require nickel, cobalt, manganese, lithium, or lithium iron phosphate. All of this demands massive mineral input, and 90% of rare earth and permanent magnet production is concentrated in China.

Environmental scrutiny of mineral supply chains has intensified. If an electric vehicle battery uses cobalt produced through child labor in the Democratic Republic of Congo, or nickel from environmentally damaging operations in Indonesia, the vehicle's overall sustainability footprint may be worse than assumed. The same ESG considerations once applied to oil and gas are now being introduced into the mining sector.

Regulations are also focusing on what happens at the end of a project's life cycle. Wind turbines have significant environmental impact, and solar panels are difficult to recycle. The EU Critical Raw Materials Act now requires a minimum percentage of recycled material in battery manufacturing. Battery storage projects must plan for material recycling once batteries reach end of operating life. This focus on full lifecycle environmental impact represents one of the biggest regulatory changes as the sector has matured.

Western nations trying to rebuild critical mineral supply chains face enormous permitting and legal hurdles. Over many years, very few mines have been constructed in the United States or Europe. In Serbia, Rio Tinto's lithium project has encountered massive public resistance. Mining has fallen out of public consciousness and is widely perceived as a dirty, extractive industry.

Expediting mine permitting is essential - it's impossible to rebuild mining industry capacity if projects take 15 years to develop. There is a lost generation in the United States, where no one has been involved in constructing new mines during an extended period. Even in Canada and Western Australia - among the most sophisticated mining jurisdictions in the world - navigating legal hurdles for permitting is difficult and time-consuming.

The EU has approved 47 strategic mineral projects and aims to streamline planning, consenting, and environmental permitting. However, from a legal perspective, it is hard to see how much time can actually be cut when affected communities can bring legal actions against nearby mine developments. A profound cultural shift is needed - one that repositions mining as a matter of national security, jobs, and industrial capability.

A fundamental challenge for western governments is that current mineral prices don't support new mine construction. Prices for lithium, rare earths, copper, and cobalt are not sending a signal that investors should build more mines, even though security of supply is a massive strategic issue.

The reason lies in the processing stranglehold held by China and, in the case of nickel, Indonesia. These countries are incentivized to keep prices low enough to prevent more expensive western projects from being financed. For governments that see a strategic requirement for these materials, the challenge is how to make projects viable in a hostile price environment.

Two approaches are emerging. The first is the carrot: government funding, offtake support, and guaranteed return levels for project developers. The second is the stick: taxing materials sourced through carbon-intensive or environmentally damaging processes when they enter EU borders. Floor pricing mechanisms that give investors confidence in minimum return levels could also make projects financeable.

The MP Materials-Ma'aden joint venture represents a model for what might be called "new globalization" - partnerships between friendly nations rather than open global markets. Canada and the United Kingdom are natural partners, with the UK offering high-tech industries and capital while Canada provides raw materials and manufacturing capability.

A significant regulatory divergence has emerged between the United States and the European Union on ESG standards. The US administration is putting pressure on companies and fund managers to step back from ESG principles, while the EU, UK, and Canada continue to view ESG as a fundamental building block of business rather than a virtue signaling exercise.

The EU is the world's biggest trading block, and battery manufacturers will not be able to operate there without demonstrating high ESG compliance. ESG standards also function as a competitive tool - they make it more costly for polluting companies to do business in the EU, effectively driving competitiveness for compliant companies.

For mining companies, ESG compliance has workforce implications as well. The mining industry is competing with big tech for talent, and the next generation of professionals won't work for companies perceived as environmental offenders. With artificial intelligence in exploration becoming a major selling point, mining companies need to attract technology-savvy talent and can't afford to be seen as old economy operations.

What constitutes a critical mineral is evolving rapidly. While many associate the term with battery minerals like cobalt and lithium - historically tiny markets - the definition now encompasses much larger commodity sectors.

Copper is becoming critical due to electrification. Electrifying energy and transport requires dramatically more copper than traditional systems. Aluminium is the most obvious substitute for copper and is increasingly included in critical mineral lists. Even steel and iron ore are being treated as critical in some jurisdictions because of their essential role in infrastructure development.

As the definition broadens, the markets governments seek to protect grow much larger. And even for genuinely small-market minerals like rare earths, the applications are so essential for national security that no country can afford to ignore them.

Data analytics has become a hugely significant aspect of the energy and mining world. Companies like Modo Energy demonstrate how data-driven services - in this case, analytics for battery storage optimization - are creating entirely new business models without requiring physical asset ownership.

AI-driven exploration strategies are gaining serious investor attention. Companies using AI in mineral exploration have been more successful in raising capital than traditional mining companies, signaling that the market values technology-enabled approaches.

For the legal profession, AI is already changing the way work gets done. Large-scale contract review projects that once required weeks of manual work will increasingly be handled by AI. The next generation of mining and energy lawyers will need to be conversant with these technologies and the risks they introduce.

The legal specialties emerging at the intersection of mining, energy, and technology - including data governance, AI ethics, and tech-enabled compliance - represent significant career opportunities as the industry continues its transformation.
