BASIS OF REPORT PREPARATION

This report was prepared in accordance with the Extractive Sector Transparency Measures Act (“ESTMA” or the “Act”) issued by the Government of Canada. The information in this report was prepared by Barrick Mining Corporation (formerly Barrick Gold Corporation) (“Barrick”) for the sole purpose of complying with Barrick’s obligations under the ESTMA. The information contained in this report is provided solely for the benefit of Natural Resources Canada (“NRCan”) and in connection with Barrick’s obligations under the ESTMA. This report may not be used or relied upon by any other person or for any other purpose without Barrick’s express prior written consent.

1 > PROJECTS

According to the Technical Reporting Specifications issued by NRCan, a project is the operational activities that are governed by a single contract, license, lease, concession or similar legal agreement and form the basis for payment liabilities with a government. If multiple agreements are “substantially interconnected”, they are considered a single project. “Substantially interconnected” means forming a set of operationally and geographically integrated contracts, licenses, leases or concessions or related agreements with substantially similar terms that are signed with a government and give rise to payment liabilities.

This report includes payments made that are reportable under ESTMA for all of Barrick’s controlled projects, regardless of Barrick’s ownership interest. In accordance with the Act, this report does not include payments made by projects that Barrick does not control, except if payments were made by a Barrick controlled entity in relation to the project. Projects that Barrick has an economic interest in but are not controlled by Barrick consist of the following:

	Place of Business	Entity Type	Interest			Accounting Method
Norte Abierto Project	Chile	Joint Operations		50	%	Our share
Donlin Gold Project1	United States	Joint Operations		50	%	Our share
Veladero	Argentina	Joint Operations		50	%	Our share
Porgera Mine	Papua New Guinea	Joint Venture		24.5	%	Equity method
Kibali	Democratic Republic of Congo	Joint Venture		45	%	Equity method
Jabal Sayid	Saudi Arabia	Joint Venture		50	%	Equity method
Zaldívar	Chile	Joint Venture		50	%	Equity method

¹ Donlin Gold LLC is a non-reporting U.S. entity. Its shares are owned 50/50 by Barrick Mining Corporation and NovaGold Resources Inc. (“NovaGold”). Neither Barrick nor NovaGold control Donlin Gold LLC. In accordance with the additional guidance provided by NRCan in August 2017 and April 2018, NovaGold has included 100% of payments made by Donlin Gold LLC to enhance transparency. On April 22, 2025, Barrick announced that it had entered into an agreement to sell its 50% interest in the Donlin Gold project which is subject to the satisfaction of customary closing conditions and obtaining the required regulatory approvals. The transaction is expected to be completed late in the second quarter or early in the third quarter of 2025. 

Non-significant projects, in which insignificant payments to governments were made, have been grouped together and presented as exploration sites, closed sites, or projects.

Non-project specific payments relate to payments made for the commercial development of minerals that have been calculated and paid on a consolidated basis and are difficult to split or disaggregate to a specific project.

2 > GOVERNMENTS

Government is defined as:

(a) any government in Canada or in a foreign state

(b) a body that is established by two or more governments

(c) any trust, board, commission, corporation or body or authority that is established to exercise or perform, or that exercises or performs, a power, duty or function of government for a government referred to in paragraph (a) or a body referred to in paragraph (b).

3 > REPORTING CURRENCY

Reportable payments to governments have been disclosed in United States (“US”) dollars, unless otherwise shown. This is consistent with Barrick’s functional currency for consolidated accounting purposes. Payments denominated in currencies other than US dollars were translated using the exchange rate at the time the payment was made. The average exchange rates for 2024 are as follows:

Currency	Average Exchange Rate
Argentinean peso	ARS per USD	916.02
Canadian dollar	CAD per USD	1.37
Chilean peso	CLP per USD	943.75
Dominican peso	DOP per USD	59.42
Pakistani Rupee	PKR per USD	278.51
Papua New Guinean Kina	PGK per USD	3.85
Peruvian sol	PEN per USD	3.75
Tanzanian Shilling	TZS per USD	2,597.40
West African CFA franc	XOF per USD	606.43
Zambian kwacha	ZMW per USD	26.16

4 > PAYMENTS

Reportable payments made to governments are presented on a net cash basis for the year ended December 31, 2024.

Any payment, whether made as a single payment or a series of payments, below $73,020 (CAD $100,000 threshold as set out under the Act converted to USD using the full year average exchange rate) in a given category to a particular government was not reported.

Reportable payments have been rounded to the nearest $10,000 but rounding was not to be used for determining the threshold for what to include as a reportable payment.

A) Taxes

This category consists of taxes paid to governments based on income, profit or production in relation to the commercial development of minerals. The following are not included in total payments to governments:

• Consumption tax, such as value-added tax, excise tax and custom tax

• Personal income tax

• Withholding tax (except that withholding taxes for tax obligations of Barrick affiliates that relate to the commercial development of minerals are included in this report)

• Taxes which were offset by credits that were received prior to the reported tax payment being made.

• Other taxes that do not relate to the commercial development of minerals, such as payroll tax, stamp tax and personal asset tax

B) Royalties

This category consists of royalties paid to governments relating to the commercial development of minerals. No royalties paid in kind have been made to governments for the year ended December 31, 2024.

C) Fees

This category consists of fees paid to governments relating to the commercial development of minerals, such as permit and license fees. This does not include amounts paid in the ordinary course of commercial transactions in exchange for services provided by governments, such as utilities paid at market rates.

D) Production entitlements

This category includes payments made to governments relating to a share of production under production sharing agreements. There were no production entitlements payments made to governments for the year ended December 31, 2024.

E) Bonuses

This category includes signing, discovery, production and any other type of bonuses paid to governments. There were no bonus payments made to governments for the year ended December 31, 2024.

F) Dividends

This category consists of dividends paid to governments on shares given in lieu of a bonus, production entitlements, royalties or other fees. This does not include dividends paid to governments as an ordinary shareholder. For the year ended December 31, 2024, dividends were paid by Société des Mines de Gounkoto SA (Gounkoto) and Société des Mines de Loulo SA (Somilo) to the State of Mali based on the State of Mali’s shareholding pursuant to the Establishment Convention under which Gounkoto operates. There were no dividends paid to governments on shares in lieu of a bonus, production entitlements, royalties or other fees for the year ended December 31, 2024.

G) Infrastructure improvement payments

This category consists of payments made to governments for the construction of public infrastructure, such as roads, schools and hospitals that directly relate to the commercial development of minerals. This does not include infrastructure improvement payments that relate primarily to the operational purposes of Barrick. Payments are reported in the period in which the payment was made.
