SPOTLIGHT #23: Oil Price Surge and Mining Operations: What Legal Risks Should Mining Companies Watch For?

Lead up Spotlight #23 focuses on the impact of the recent oil price surge on mining operations worldwide, and the legal risks this creates for mining companies and their contractual counterparties.

A sector under pressure

The Strait of Hormuz crisis , discussed in detail in our Spotlight #22, has delivered an acute energy shock to commodity markets. Brent crude, which traded around $70 per barrel at the start of 2026, surged above $100 per barrel by mid-March, touching nearly $120 as we are writing. For mining companies, this is not anecdotical: oil and petroleum-derived products are key elements of mining economics.

Diesel fuels the haulage fleets and heavy machinery on which every open-pit or underground mine depends. Explosives, ANFO and emulsions, are manufactured from petroleum-derived ammonium nitrate and fuel oil. Likewise, processing plants are energy-intensive, and where power is generated on-site by diesel generators, the correlation with crude prices is direct. According to BMO Capital Markets, analysed by Mining.com, a sustained oil price around $100 per barrel , roughly 47% above the 2025 average , could push iron ore production costs up approximately 20%, copper costs by 16%, and gold costs by around 9%. By the same token, iron ore operations are the most sensitive, with costs increasing roughly 4.2% for every 10% rise in oil prices.

These figures are consistent with S&P Global Market Intelligence’s 2026 mine cost outlook, which had already projected a 6.25% year-on-year increase in fuel costs for the mining sector before the Hormuz crisis. The same report identifies fuel as a primary driver of all-in sustaining costs (AISC) across twelve key metals, reinforcing the sector’s deep structural exposure to oil price volatility.

The practical consequences are easy to grasp. Mining operators in diesel-dependent jurisdictions , notably those which are lacking the proper electrical infrastructure , are reporting accelerating cost pressure on active projects. In a capital-intensive industry where project economics are modelled years in advance, an unhedged price change of this magnitude can rapidly transform a viable mine into a loss-making one.

Contractual exposure: when financial models break down

Mining projects are underpinned by a web of long-term contracts: offtake agreements committing to supply at fixed or formula-linked prices; EPC (Engineering, Procurement and Construction) contracts with fixed lump-sum or target-cost pricing; and supply agreements for fuel, explosives and reagents. These contracts are typically negotiated on the basis of specific economic assumptions about input costs. When those assumptions fail, the contractual allocation of risk becomes the critical battleground.

Three mechanisms are particularly relevant in the current environment:

Price indexation clauses. Long-term supply agreements often include price adjustment mechanisms tied to recognised fuel or energy indices. Mining companies that negotiated such provisions will find themselves partly insulated. Those that did not , or whose indices lack proper calibrating, face cost overruns that fall squarely on their own P&L.

Hardship, force majeure and renegotiation clauses. Many contracts relating to mining operations contain hardship clauses allowing a party to request renegotiation when changed circumstances fundamentally alter the equilibrium of the contract. The key question is whether the recent oil price surge (of this magnitude and speed) qualifies as the kind of exceptional, unforeseeable event that triggers such a provision. This qualification will depend on the specific contractual terms, the governing law, and whether energy price volatility of this scale could reasonably have been anticipated at the time of contracting.

Fixed-price EPC exposure. Contractors who agreed fixed-price EPC contracts without adequate escalation provisions are likely to face severe margin compression. Owners, conversely, may find their contractors seeking relief or, in extreme cases, threatening to demobilise. Both scenarios carry significant project delivery risk and create fertile ground for disputes.

Dispute risk: a familiar pattern

Historically, the mining sector has seen a wealth of disputes arise following energy price shocks. The 2007–2008 commodity and energy price spike, and again the post-COVID inflationary surge of 2021–2022, both generated waves of contractual claims centred on cost overruns, delay, and frustrated performance. The current Hormuz-driven oil shock follows the same logic, but with particular intensity given its speed and geographic concentration.

Mining companies and their counterparties are already confronting a familiar set of legal questions: does the oil price surge constitute a force majeure event? Does it trigger hardship provisions? Can a contractor or supplier suspend performance? The doctrinal analysis of these mechanisms, including the differences between French law, English law and international instruments such as the UNIDROIT Principles, is covered in detail in Lead up Spotlight #22.

What Spotlight #22 makes clear is that the answer depends critically on the applicable law, the precise contractual wording, and the specific factual context. In other words, there is no universal answer, and companies that assume they are either automatically protected or automatically exposed are likely to be wrong.

What is predictable, however, is the pattern that follows: a party facing unmanageable cost escalation will first attempt renegotiation; if that fails, it will invoke contractual relief mechanisms; and if those prove insufficient, arbitration or litigation follows. Getting the legal analysis right at the earliest stage, and complying meticulously with contractual notice requirements, is therefore decisive.

Practical recommendations

• Audit your contracts now. Identify all active agreements with material exposure to fuel or energy input costs. Map the applicable price adjustment, hardship, and force majeure provisions. Most importantly, understand your notice obligations and deadlines, failure to comply with contractual notification requirements can extinguish rights that would otherwise be available.
• Assess your hedging and indexation position. Where fuel hedging or price indexation mechanisms exist, verify their calibration against current market conditions and ensure compliance with any trigger or reporting requirements. Where such mechanisms are absent, consider whether commercial hedging instruments can limit exposure going forward.
• Engage counterparties early. If cost escalation is already materially affecting performance, initiate structured dialogue with counterparties before the situation becomes adversarial. Early, documented engagement demonstrates good faith and may lay the groundwork for a negotiated solution that avoids the cost and disruption of formal dispute proceedings.
• Take legal advice before invoking relief mechanisms. Invoking force majeure or hardship clauses without a sound legal basis can itself constitute a breach of contract. Given the scale of the financial stakes in mining disputes, the cost of early legal advice is negligible compared to the risk of an ill-considered unilateral step. Governing law matters: the analysis under French law, English law and international instruments differs substantially.
