Plan for Confidentiality Early in Southern African Mining Arbitration Disputes

Arbitration is widely regarded as an effective method for resolving both domestic and cross-border mining disputes because it offers a level of privacy that traditional court proceedings often cannot.

In the Southern African mining sector, where disputes frequently involve commercially sensitive information, technical data, and complex investment structures, confidentiality is one of arbitration’s biggest attractions. However, recent mining disputes across Africa have highlighted an important reality: arbitration does not automatically guarantee confidentiality, and businesses must proactively plan for it from the very beginning of a dispute.

Mining companies, investors, contractors, and funders operating across multiple African jurisdictions increasingly rely on arbitration clauses in commercial agreements to resolve disputes efficiently and privately. Arbitration agreements are usually included in contracts at the outset of a commercial relationship or agreed upon separately once a dispute arises. In many cases, parties choose established arbitral institutions whose rules contain confidentiality provisions designed to protect sensitive information.

For example, the Arbitration Foundation of Southern Africa International Rules provide a default confidentiality framework for disputes administered under its rules. Similarly, the International Chamber of Commerce Arbitration Rules empower tribunals to issue confidentiality orders and protect trade secrets and commercially sensitive material.

These protections are often viewed as essential in mining disputes, where confidential geological data, pricing structures, production forecasts, funding arrangements, regulatory compliance records, and investment details can significantly impact market conditions and investor confidence if disclosed publicly.

South Africa’s International Arbitration Act 2017 further reinforces confidentiality by incorporating the UNCITRAL Model Law principles into domestic legislation. Under Section 11 of the Act, arbitration proceedings involving private parties are considered confidential, including the arbitration award and related documentation, unless disclosure is required by law or necessary to protect legal rights. However, the Act also introduces an important limitation. When a public body is involved in the arbitration, proceedings may become open to the public unless the tribunal orders otherwise. This creates a major concern for mining disputes because governments and state-owned entities are often parties to mining projects, licences, and investment agreements throughout Southern Africa.

The confidentiality risks become even greater in cross-border disputes that eventually reach national courts. While arbitration itself is private, court proceedings are generally public. Parties seeking to enforce arbitral awards often need to file arbitration documents in court, including the award itself, which can expose sensitive information to public scrutiny. Courts may also compel disclosure of arbitration records where necessary for legal proceedings, further weakening confidentiality protections.

A recent Gauteng High Court judgment in Johannesburg demonstrates these risks clearly. The case involved a cross-border mining investment dispute connected to proceedings in Tanzania. A South African company related to one of the parties sought declaratory relief regarding the scope of a confidentiality agreement. The court ultimately confirmed that confidentiality obligations are contractual in nature and bind only those entities that are expressly party to the agreement. Because the related company had not signed the original confidentiality agreement, it was not bound by its terms.

This judgment is significant for the mining industry because it confirms that confidentiality protections do not automatically extend across corporate groups, subsidiaries, or affiliated investment entities unless expressly stated in contractual agreements. It also highlights another important issue: disputes about confidentiality can themselves become public through court litigation, potentially exposing the very information parties intended to protect.

To reduce these risks, courts in South Africa and other jurisdictions have developed several protective mechanisms that allow sensitive information to remain restricted even during litigation. One commonly used method is the implementation of confidentiality ring regimes, where access to sensitive information is limited to external lawyers and independent experts on a strict need-to-know basis. In some cases, the parties themselves are excluded from viewing certain documents.

Another approach involves the use of redacted documents and partial disclosure processes, allowing only the information strictly necessary for the resolution of the dispute to be disclosed in court. Courts may also require confidentiality undertakings from all individuals granted access to sensitive information, creating legally enforceable obligations against misuse or further disclosure. In highly sensitive matters, judges may allow confidential pleadings and evidence to be heard in camera, meaning proceedings are conducted privately with limited public access.

For mining companies operating in Southern Africa, the key lesson is that confidentiality should never be treated as automatic simply because arbitration is chosen as the dispute resolution mechanism. Businesses should negotiate carefully drafted confidentiality clauses at the contract stage and ensure those protections extend across corporate affiliates, investors, and related entities. Companies should also establish internal protocols governing the handling of commercially sensitive material throughout the life cycle of a dispute.

Cross-border mining disputes often involve multiple legal systems, regulators, public institutions, and financing partners, all of which increase the possibility of confidential information entering the public domain. Even where arbitration offers a greater degree of privacy than traditional litigation, the involvement of courts in enforcement proceedings can significantly reduce those protections.

As mining investment across Southern Africa continues to grow, businesses must adopt a proactive approach to dispute confidentiality management. Arbitration remains a valuable tool for resolving complex mining disputes, but recent cases demonstrate that privacy and confidentiality are not guaranteed. Careful drafting, strategic planning, and ongoing protection of sensitive information are essential to safeguarding commercial interests, investor confidence, and reputational standing in the mining sector.
