Global Mining Faces $260 Billion Investment Gap by 2035, Raising Risks for the Energy Transition

The global mining industry is entering a critical phase as the world accelerates toward decarbonization, electrification, and a more digitally driven economy. Demand for [[PRRS_LINK_1]] such as copper, lithium, nickel, cobalt, and rare earth elements is rising sharply, yet investment is not keeping pace. Analysts warn that the sector must attract more than $250–$260 billion in new capital by 2035 to avoid serious supply shortages that could slow the global energy transition.

Without this level of investment, the world risks structural bottlenecks in essential materials used for renewable energy systems, electric vehicles, power grids, data centers, and advanced industrial technologies. The gap highlights a growing disconnect between long-term demand and current project development pipelines across the global mining sector.

A Deep Structural Shortfall in Mining Capital

The current [[PRRS_LINK_2]] gap is the result of more than a decade of underinvestment. Following the commodity downturn of the mid-2010s, mining companies reduced exploration budgets and focused on balance sheet stability rather than expansion. While demand for minerals has since rebounded strongly, the supply pipeline has failed to recover at the same pace.

This imbalance is now becoming increasingly visible. Exploration spending has not kept up with rising consumption, leading to fewer major discoveries. At the same time, declining ore grades, stricter environmental rules, and rising development costs are making new projects more expensive and time-consuming.

Most large mining projects require 10 to 15 years to move from discovery to production. This long lead time means that investment decisions made today will determine supply availability well into the next decade, increasing the urgency of closing the capital gap.

Copper: The Core Metal of Electrification

[[PRRS_LINK_3]]sits at the heart of the global energy transition. Its conductivity makes it essential for electric vehicles, renewable energy [[PRRS_LINK_4]], power transmission networks, and rapidly expanding data centers supporting artificial intelligence.

Global copper demand is projected to rise from around 26 million tonnes per year to more than 35 million tonnes by 2035, creating a significant supply deficit unless new projects are developed at scale. Copper mining is highly capital-intensive. Major projects typically require between $2 billion and $10 billion in investment, with internal rates of return averaging 12–16%.

Key developments shaping future supply include:

• Kamoa-Kakula (DRC): Over $19 billion invested, with production exceeding 800,000 tonnes annually
• Oyu Tolgoi (Mongolia): More than $7 billion in underground expansion
• Quellaveco (Peru): Around $5.5 billion investment, producing ~300,000 tonnes annually
• Mingomba (Zambia): Estimated $2.3–$2.5 billion development cost

These large-scale projects illustrate both the opportunity and financial intensity of securing future copper supply.

Lithium: The Battery Economy Engine

[[PRRS_LINK_5]]demand is expected to increase more than fourfold by 2040, driven by the rapid expansion of electric vehicles and energy storage systems. Large-scale lithium projects typically require $1.5 billion to $4 billion in capital expenditure, depending on geology and processing methods.

Major investments include:

• Thacker Pass (USA): ~$2.93 billion
• Rincon (Argentina): Over $2.5 billion
• Caucharí-Olaroz (Argentina): ~$979 million with expansion potential

These projects highlight lithium’s strategic importance in global battery supply chains and the scale of investment needed to meet future demand.

Rare Earth Elements and Strategic Supply Security

[[PRRS_LINK_6]] are essential for wind turbines, electric vehicles, defense systems, and high-tech manufacturing. Despite their importance, production remains highly concentrated geographically, creating supply chain vulnerabilities.

Key global assets include:

• Mount Weld (Australia): One of the world’s leading producers
• Kiruna Deposit (Sweden): Over 1 million tonnes of rare earth oxides
• Mountain Pass (USA): Core supplier for North America

These assets are central to efforts to diversify global rare earth supply chains and reduce dependency on dominant producers.

Financing the Future: Bridging the Investment Gap

Closing the $260 billion mining investment gap will require a combination of traditional and innovative financing structures. No single capital source is sufficient on its own.

Key funding mechanisms include:

• Project finance backed by long-term offtake agreements
• Participation from sovereign wealth funds
• Export credit agency guarantees
• Funding from development finance institutions
• Private equity and institutional capital
• Streaming and royalty agreements

Typical mining project structures show 60:40 to 70:30 debt-to-equity ratios, with weighted average costs of capital between 7% and 10%, depending on jurisdiction and risk exposure.

Regional Hotspots Driving Mining Investment

[[PRRS_LINK_7]] remains a global leader in copper and lithium production, with Chile, Peru, and Argentina attracting major capital inflows. In Africa, countries such as the DRC and Zambia are becoming central to global supply chains for cobalt, copper, and other battery metals. [[PRRS_LINK_8]] and [[PRRS_LINK_9]] are strengthening domestic production through strategic policies aimed at reducing external dependency. In Europe, initiatives like the Critical Raw Materials Act are accelerating investment in mining and processing, despite permitting delays. Central Asia and the Middle East, particularly Kazakhstan and Saudi Arabia, are emerging as new mining and refining hubs supported by sovereign investment strategies.

ESG and Sustainability Shape Investment Decisions

[[PRRS_LINK_10]] standards have become central to mining finance. Investors now require strong sustainability performance as a condition for capital access.

Modern mining projects increasingly incorporate:

• Renewable energy integration
• Water recycling systems
• Responsible tailings management
• Community engagement programs

These ESG-driven practices improve project bankability, reduce financing costs, and attract sustainability-focused capital markets.

Technology Improves Efficiency and Reduces Risk

Technological innovation is helping to offset rising costs and improve project viability across the mining sector. Tools such as artificial intelligence, automation, and digital twins are reshaping exploration and operations.

Key improvements include:

• 10–20% reduction in operating costs
• 15–25% productivity gains
• 30–40% increase in exploration efficiency

These advancements are increasingly essential for making new mining projects economically viable and environmentally sustainable.

CAPEX and Return Benchmarks

Mining investments vary widely in scale and profitability depending on commodity type.

Typical [[PRRS_LINK_11]] ranges:

• Copper: $2–10 billion
• Lithium: $1.5–4 billion
• Rare earths: $500 million–$2 billion
• Nickel and cobalt: $1–5 billion
• Processing facilities: $1–3 billion

Expected IRRs:

• Copper: 12–16%
• Lithium: 15–22%
• Rare earths: 12–18%
• Nickel and cobalt: 14–20%
• Integrated downstream projects: 18–25%

These figures underline the sector’s long-term attractiveness for institutional investors despite high capital requirements.

Policy Support Reshaping the Sector

Governments are increasingly stepping in with strategic policy frameworks to support domestic mining capacity. Key initiatives include:

• The U.S. Inflation Reduction Act
• The European[[PRRS_LINK_12]]
• Australia’s Critical Minerals Strategy

These policies aim to strengthen supply chains, reduce import dependence, and secure access to essential materials for industrial development and national security.

The global mining investment gap represents one of the most pressing risks to the [[PRRS_LINK_13]]. Without sufficient capital, supply shortages in critical minerals could slow the rollout of renewable technologies and delay global climate targets. Bridging this gap requires coordinated action between governments, investors, and industry leaders to mobilize capital, streamline permitting, and accelerate project development.

Securing the Foundations of the Future Economy

The world’s transition to a low-carbon, technology-driven economy depends entirely on secure access to critical minerals. Meeting projected demand will require more than $260 billion in new mining investment by 2035, underscoring the strategic importance of the sector.

From copper and lithium to nickel and rare earth elements, these resources form the backbone of modern infrastructure, energy systems, and digital technologies. Ultimately, closing the investment gap is not just a financial challenge—it is a prerequisite for sustaining global industrial growth, advancing decarbonization, and securing the material foundation of the future economy.
