Equatorial Files Final Arbitration Costs Submission, Holds A$7.1 Million Cash

ICSID Arbitration Nearing Conclusion with Significant Claims

Equatorial Resources Limited (ASX:EQX) has reached a critical procedural milestone in its long-running international arbitration against the Republic of Congo. Its Mauritian subsidiary, EEPL Holdings, filed the final submission on costs in April 2026 at the International Centre for Settlement of Investment Disputes (ICSID) in Washington, D.C., marking the last formal step following the November 2025 final hearing. The Arbitral Tribunal is now expected to deliver a final award, potentially in the first half of 2027, though no firm date has been set.

The dispute stems from Congo’s alleged unlawful expropriation and unfair treatment of EEPL’s investments in two iron ore projects: the Badondo and Mayoko-Moussondji projects. EEPL claims damages ranging from US$395 million to US$1.25 billion, excluding interest and costs, which themselves could add between US$134 million and US$741 million depending on valuation methods.

Adding complexity, the Tribunal has already ordered Congo to pay EEPL A$1.2 million for costs related to a prior postponement of the final hearing. This sum remains unpaid and accrues interest at 5.10% per annum since July 2025.

Legal Counsel Changes Spark New Arbitration

Following the completion of post-hearing submissions, Equatorial appointed Boies Schiller Flexner to represent EEPL during the enforcement and potential annulment phases of the arbitration. This change came after a fee dispute ended the prior engagement with Clifford Chance.

Subsequently, Clifford Chance initiated a separate arbitration against Equatorial over unpaid fees. Equatorial has stated its intention to vigorously defend this new legal challenge, adding an unexpected layer of legal proceedings amid the ICSID arbitration.

Guinea Exploration Permits Remain in Regulatory Uncertainty

Meanwhile, Equatorial’s iron ore exploration permits in Guinea’s Nimba region remain shrouded in uncertainty. The company holds majority stakes in the Nimba West and Nimba North permits, covering substantial landholdings within a prolific iron ore corridor and close to existing transport infrastructure.

Despite a public announcement by Guinea’s government in May 2025 that these permits were cancelled amid a broader regulatory review affecting over 120 mining permits, Equatorial has yet to receive formal notification. The company continues to seek clarification and maintain dialogue with Guinea’s Ministry of Mines, aiming to renew the permits and proceed with planned exploration activities, including surface sampling and a maiden drilling program.

Financial Position Supports Ongoing Legal and Exploration Efforts

At the end of June 2026, Equatorial reported a cash balance of approximately A$7.1 million with 131.4 million shares on issue. The company recorded no exploration payments during the quarter and continues to manage operating costs tightly, including director fees and administrative expenses.

This financial footing allows Equatorial to sustain its dispute resolution efforts in Congo, navigate the Guinea permit ambiguity, and pursue new opportunities in the resources sector. The outstanding A$1.2 million cost award from Congo, accruing interest, remains a potential near-term cash inflow, though its timing is uncertain.

Unresolved Questions Around Arbitration Timing and Permit Outcomes

While the ICSID arbitration edges closer to resolution, the timing of the final award remains speculative, and its content could materially affect Equatorial’s valuation. The separate arbitration with Clifford Chance introduces additional legal risk and potential costs.

Equatorial’s situation in Guinea underscores the challenges mining companies face amid shifting regulatory landscapes in West Africa. The lack of formal communication on permit status leaves the company’s exploration plans in limbo, with potential implications for project timelines and investor confidence.
