Global Industry Standard on Tailings Management

Principle 15
Public Disclosure

Barrick, as a member of the International Council on Mining and Metals (ICMM), has fulfilled its commitment to provide disclosure under the Global Industry Standard on Tailings Management (GISTM) for all of its tailings storage facilities under the GISTM by August 2026.

Barrick has also committed to provide access to detailed information about our tailings facilities under the GISTM in furtherance of our commitment to transparency and public accountability.

Of the sixty four (64) tailings storage facilities that Barrick owns, operates or has currently in design phase, only eighteen (18) are classified as ‘Extreme’ (six facilities) or ‘Very High’ (twelve facilities) under the GISTM. Of the eighteen (18) facilities fourteen (14) are in ‘Full Conformance’, one (1) in ‘Partial Conformance’, one (1) in ‘Safe Closure’, and two (2) are facilities associated with the Reko Diq Project. Twelve facilities are classified as being in ‘Safe Closure’ and are therefore not subject to the disclosure requirements of the GISTM, while one facility (Zaldivar TSF) is operated by a joint venture partner and is therefore not included in Barrick’s GISTM disclosures.

GISTM disclosure documents have been removed for the Hemlo (Ontario, Canada), Golden Patricia (Ontario, Canada), Mercur (Utah, USA) and Tongon (Ivory Coast) sites as these properties have been divested from Barrick’s portfolio since last year’s disclosure publication in August 2025.

Regarding the Reko Diq tailings facilities, Barrick announced on February 5, 2026 that it was reviewing all aspects of the Reko Diq project in light of the escalation of security risks and increased security incidents. On April 2, 2026, Barrick announced that following the preliminary findings of the review and further escalation of security issues in the region, the Company considers it necessary to slow development activity and extend the project review. Work has also paused on the Reko Diq TSFs for 2026, and therefore Barrick cannot disclose conformance to GISTM in 2026, but the tailings storage facilities were fully confirming to GISTM in 2025.

The disclosure documents on this page have been prepared in accordance with the requirements of Principle 15 of the GISTM and reviewed by Barrick’s Accountable Executive.

These disclosures will be updated as required by the GISTM.
