Series Forward
The mining sector in Latin America is entering a different phase of ESG scrutiny. What passed as sufficient over the past decade, compliance checklists, sustainability reports, audit certifications, no longer answers the questions now being asked by courts, lenders, investors, regulators, and affected communities.
In 2026, the issue is not whether a company can articulate ESG commitments. The issue is whether those commitments are supported by governance systems that hold up under legal, operational, and financing pressure.
The timing is not accidental. The EU’s evolving CSRD framework, including the Omnibus reform package and the legally effective Stop-the-Clock directive, is already reshaping disclosure expectations across global supply chains. At the same time, the English High Court’s 2025 judgment in Município de Mariana v BHP, followed by the refusal of permission to appeal in January 2026, has altered how courts assess parent company exposure in the mining sector.
Three areas capture that shift.
Water, biodiversity, and Indigenous rights now sit at the center of project viability, particularly across the lithium and copper corridors of the Andes. Water is no longer a permitting input. In many cases, it determines whether a project moves at all.
Disclosure has moved beyond communications. It now operates as a control framework subject to diligence, assurance, and financing scrutiny. The question is no longer what is reported, but whether it can be supported.
Tailings governance has moved decisively into the boardroom. Recent litigation confirms that liability analysis will follow operational control, not corporate structure.
These issues do not operate in isolation. Weak water governance becomes social conflict. Social conflict becomes a disclosure issue. Disclosure gaps affect financing. Governance failures become evidence.
This series is written for boards, general counsel, ESG leaders, and financial institutions working in Latin American mining. The focus is practical: what governance looks like when it is tested.
Article 1
Water Is the New Permit
Water now sits at the center of mining risk.
Across the lithium and copper corridors of the Andes, water is no longer just an environmental variable. It is a permitting constraint, a trigger for social conflict, a source of legal exposure, and often the deciding factor in whether a project proceeds.
Indigenous rights define the legal boundary
The legal framework is established. The difficulty lies in its application.
ILO Convention No. 169 recognizes Indigenous Peoples’ rights over lands and natural resources, including participation in their use and management. UNDRIP affirms rights to land and water, and to Free, Prior and Informed Consent before approval of projects affecting those resources. Inter-American jurisprudence, including Saramaka People v. Suriname and Lhaka Honhat v. Argentina, makes clear that large-scale extractive activity affecting Indigenous territories may require consent where impacts are significant.
The right to water is increasingly treated as an independent human right under international law, including through interpretation of the International Covenant on Economic, Social and Cultural Rights.
The implication is direct. Water conflict is not only a permitting issue. It creates exposure across domestic courts, regional systems, lender frameworks, and investor scrutiny.
The consultation record is now evidence
Consultation is no longer procedural. It is evidentiary.
Where records do not show how participation occurred, whether dissent was captured, and how different community perspectives were reflected, the company’s position weakens.
One gap appears consistently: gender
Consultation processes often rely on formal representation without capturing gender-differentiated participation. In many Andean communities, women have distinct relationships to land and water. Where those perspectives are not recorded independently, the evidentiary record is incomplete.
This is increasingly identified in IFC Performance Standard reviews and human rights due diligence.
Basin risk is the issue most companies still understate
Project-level assessments routinely understate risk in multi-project basins.
The issue is cumulative impact.
Where multiple operators draw from interconnected systems, project-level models fail to capture basin-wide effects. In basins such as the Atacama, this leads to systematic underestimation of drawdown risk.
Leading operators are beginning to respond with basin-level hydrological studies, shared monitoring frameworks, and disclosure of withdrawal relative to sustainable yield.
This is not yet standard practice. It is becoming expected.
What distinguishes leading operators is not intent, but design.
Desalination and seawater infrastructure reduce dependence on highland aquifers. Closed-loop systems increase recirculation. Basin-level accounting replaces site-level metrics. Real-time monitoring reduces information asymmetry with communities.
These measures require capital. They also reduce the cost of conflict.
Benefit-sharing is the missing link
FPIC processes often emphasize procedure over outcome.
Revenue-sharing structures, equity participation, and independently governed community funds increasingly determine whether a project is seen as partnership or imposition.
This is not a community relations issue. It is a structuring issue.
Grievance mechanisms form part of that structure. Where they are accessible, credible, and used, they function as early-warning systems. Where they are not, lenders and investors treat that absence as a governance signal.
Closing thought
Water is no longer part of the permit. In many cases, it is the permit.
Article 2
From ESG Storytelling to Decision-Grade Disclosure
The disclosure environment has shifted in kind, not just degree.
The question is no longer whether ESG information is published. It is whether the underlying data can withstand scrutiny.
European regulation matters even where it does not apply directly
Disclosure pressure now moves through commercial relationships.
That pressure is contractual.
The regulatory landscape is also more fluid than many assume. The Stop-the-Clock directive has delayed certain CSRD timelines and is already in force. The broader Omnibus reform package remains in development.
Companies should plan against current obligations while monitoring where the framework is moving.
Data is now a condition of capital access
European investors must report standardized indicators across portfolios.
The effect is practical. Data flows upstream.
A second pressure channel operates through SFDR. Principal Adverse Impact reporting requires portfolio-level data on emissions, water, biodiversity, and human rights. That requirement translates directly into requests to operating companies.
Data is not optional. It is a condition of participation.
GRI 14 has removed ambiguity
GRI 14 establishes water, tailings, Indigenous rights, and biodiversity as baseline topics for the mining sector.
Alongside this, the EU Deforestation Regulation introduces indirect exposure. Mining is not directly regulated, but land use, procurement, and group-level activities can create obligations.
Assessment needs to occur at the corporate group level.
Internal audit is the missing piece
In many organizations, ESG data governance operates without internal audit involvement.
The result is predictable. Weak controls, inconsistent methodologies, and late-stage reconciliation.
Integrating ESG into audit scope improves data integrity and reduces assurance risk. This is not administrative. It is structural.
A minimum credible framework
Each material KPI should have a defined methodology, a responsible owner, and a clear audit trail.
The move from limited to reasonable assurance should be planned.
For companies with international exposure, the ability to respond to supply chain data requests matters as much as formal reporting scope.
Closing thought
Disclosure is moving toward proof.
Article 3
Tailings as Governance
Tailings risk now sits at the center of governance.
The legal landscape has changed
The Mariana judgment provides the clearest recent example.
The English High Court found BHP strictly liable under Brazilian environmental law based on operational control. It also found fault-based liability, concluding that the risk of failure was foreseeable.
The refusal of permission to appeal reinforces the significance of that reasoning.
Liability followed conduct.
Structure does not insulate conduct
This approach aligns with broader common law developments.
Cases such as Vedanta and Okpabi confirm that liability turns on operational involvement. Corporate form does not provide insulation where control is exercised in practice.
Governance must replace reliance on certification
The Brumadinho failure illustrates the limits of certification.
Third-party assessments did not prevent collapse. Certification informs decisions. It does not replace governance.
GISTM reframes the issue
A distinction is emerging between self-declared alignment and independently verified conformance.
External stakeholders are beginning to focus on that distinction.
Parent-level exposure
D&O insurers are reassessing coverage.
Where operational control exists, exposure may extend beyond what boards assume is covered.
Tailings and closure
Tailings governance and closure planning intersect in long-term liability, financial provisioning, and community obligations.
Separating them understates risk.
Capital and insurance
Insurance markets have tightened. GISTM alignment is increasingly a condition of coverage.
Governance quality now affects both cost and access to capital.
Closing thought
The question is not whether tailings governance is costly.
It is whether failure is survivable.
