Key Commodities Driving Investment Growth

The report meticulously breaks down the financing trends by commodity, revealing significant shifts aligned with global economic and technological priorities. Unsurprisingly, minerals critical to the energy transition and advanced manufacturing dominate the growth figures:

Copper: As a foundational metal for electrification and renewable energy infrastructure, copper attracted the largest share of identified financing. Funding for copper mining in tropical forest regions rose by 42% over the decade, climbing from $14.5 billion in 2016 to $20.6 billion in 2025. This sustained investment reflects copper’s indispensable role in everything from electrical grids and wiring to electric vehicles (EVs) and wind turbines, positioning it as a cornerstone commodity for the decarbonization efforts worldwide.
Lithium: Perhaps the most dramatic surge was observed in lithium financing. Essential for the burgeoning electric vehicle battery market, funding for lithium projects in these regions skyrocketed by an astonishing 1,113%. This propelled lithium financing from a relatively modest $170 million in 2016 to a substantial $2 billion in 2025. This exponential growth mirrors the rapid expansion of EV manufacturing and the global race to secure raw materials for next-generation energy storage solutions.
Nickel: Another critical component in EV batteries, as well as stainless steel production, nickel financing also experienced robust growth. The report indicates an increase of 183% for nickel operations, reaching $1.6 billion in 2025. The demand for high-purity nickel, particularly Class 1 nickel, is projected to continue its upward trajectory as battery technologies evolve and market penetration for EVs deepens.

These figures collectively highlight the profound impact of the global energy transition on mining investment patterns, directing significant capital towards the extraction of these key minerals. However, the concentration of these deposits in ecologically sensitive regions creates a complex dynamic, challenging the industry to innovate in sustainable extraction and processing.

The Grota do Cirilo Case Study: A Microcosm of Macro Concerns

To illustrate the tangible risks associated with this surge in financing, the Forests & Finance coalition spotlights Brazil’s Grota do Cirilo lithium operation, owned by Sigma Lithium, as a critical case study. This operation, located in a tropical forest-rich area, encapsulates many of the environmental and social challenges flagged by the report.

The report raises several specific concerns regarding the Grota do Cirilo project:

Environmental Licensing: Questions have been posed regarding the rigor and adequacy of the environmental licensing processes for the operation, suggesting potential gaps in the regulatory oversight or the implementation of mitigation measures.
Water Access: Concerns around water access highlight the potential for mining operations to strain local water resources, impacting nearby communities and ecosystems, particularly in regions already susceptible to water stress.
Waste Management: The report specifically addresses waste management practices at the site, an area frequently identified as a significant environmental risk in mining. This includes the responsible disposal and long-term stability of tailings and waste rock.
Community Consultation: The report also flags issues concerning consultation with the nearby Baú Quilombola community. Effective and culturally appropriate engagement with Indigenous peoples and local communities is a cornerstone of achieving a social license to operate, and any perceived shortcomings can lead to significant operational delays and social conflict.

Furthermore, the coalition cites specific concerns related to waste-rock management and slope stability at the Grota do Cirilo operation. Notably, a reported slope failure near a kindergarten in December 2025, coupled with subsequent inspections of waste piles, casts a serious shadow on the operational integrity and safety protocols in place. Such incidents raise critical questions about how mining operators are monitoring geotechnical conditions, managing waste facilities, and meticulously documenting compliance with environmental requirements. These findings at Grota do Cirilo serve as a stark reminder that inadequate planning or oversight in these areas can have severe consequences, threatening both the environment and the safety of local populations.
