Geologically Driven Asset Management Delivers Barrick’S Third Successive Year Of Reserve Growth At Sustained Quality, While Unlocking Embedded Growth Portfolio


(MENAFN- GlobeNewsWire - Nasdaq) All amounts expressed in US dollars

TORONTO, Feb. 08, 2024 (GLOBE NEWSWIRE) -- Barrick Gold Corporation (NYSE:GOLD)(TSX:ABX) grew attributable proven and probable gold mineral reserves by 5.0 million ounces before 2023 depletion, while continuing to maintain the quality of the mineral reserve base. Attributable proven and probable mineral reserves now stand at 77 million ounces2 at 1.65g/t, increasing from 76 million ounces3 at 1.67g/t in 2022. Led by the Africa & Middle East region, Barrick has delivered a third consecutive year of organic gold reserve growth over and above annual depletion. This unremitting focus on asset quality has successfully delivered replacement of over 140%4 of the company's gold reserve depletion since end of year 2019, adding almost 29 million ounces4 of attributable proven and probable reserves or 44 million ounces4 of proven and probable reserves on a 100% basis (excluding acquisitions and divestments).

Successful drilling programs at Lumwana drove the growth of proven and probable copper reserves by 330 thousand tonnes2 of copper in 2023. As a result, Barrick replaced 124% of annual global copper depletion at a consistent quality, effectively maintaining attributable proven and probable copper mineral reserves of 5.6 million tonnes2 at 0.39% in 2023.

Attributable measured and indicated gold resources for 2023 stand at 180 million ounces2 at 1.06g/t, with a further 39 million ounces2 at 0.8g/t of inferred resources. Attributable measured and indicated copper resources for 2023 stand at 21 million tonnes2 of copper at 0.39%, with a further 7.1 million tonnes2 of copper at 0.4% of inferred resources. Mineral resources are reported inclusive of reserves and are based on a gold price of $1,700/oz1 and an updated copper price of $4.00/lb1 for 2023.

President and chief executive Mark Bristow said Barrick's strategy of investing in organic growth through exploration and mineral resource management has set us apart within the industry, creating real value through discovery and development, rather than relying upon increases in commodity prices to provide value to high premium mergers and acquisitions.

“In order for our industry to help build a better world, we have to invest in our own future by creating value through exploration, leveraging our capital infrastructure base by replacing the ounces that we mine, which in turn enables us to provide multi-generational investment in our communities, developing local service provider partnerships, and investing in improving our operating environments” said Bristow.

Mineral Resource Management and Evaluation Executive Simon Bottoms stated that the company's reserves at a price of $1,300/oz for gold1 and $3.00/lb for copper1 demonstrate the quality differentiation of our assets relative to our peers.“Barrick's core focus on geologically driven asset management, not only underpins the company's reserve replacement record, but is also key in unlocking the embedded organic growth portfolio to increase the production profile to approximately 6.5 million gold equivalent ounces5 per year by the end of this decade, as both the Reko Diq and Lumwana Super Pit expansion projects are on track to complete their respective feasibility studies by the end of 2024” said Bottoms.

The Africa & Middle East region, replaced 165% of the regional 2023 gold reserve depletion, led by Loulo-Gounkoto, with extensions of the high grade Yalea orebody, delivering a 1.1 million ounce2 increase in attributable proven and probable reserves before depletion. Bulyanhulu also delivered strong results through the extension of Reef 1 and Reef 2 near surface mineralization, with updated feasibility studies supporting an additional surface decline access portal for each Reef, adding 0.9 million ounces2 to attributable proven and probable reserves. At Kibali, the ongoing conversion drilling in the 11000 lode in KCD underground combined with the conversion of some satellite pit resources delivered a 0.47 million ounce2 increase in attributable proven and probable reserves before depletion.

The Lumwana copper mineral reserve base also grew by 6% year on year, net of depletion, as a result of ongoing conversion drilling in the Malundwe Pit. This also resulted in the updated 2023 measured and indicated copper resources for Lumwana, which stand at 7.1 million tonnes2 of copper at 0.52%, with a further 4 million tonnes2 of copper at 0.4% of inferred resources, which are expected to provide the foundation for a Tier One Copper Asset6 with the completion of the Super Pit Expansion feasibility study in 2024.

Within the Latin America & Asia Pacific region, a pre-feasibility study was completed on the expansion of the leach pad supporting an additional pushback in the open pit at Veladero, resulting in 2023 attributable proven and probable gold reserves for the region of 27 million ounces2 at 0.96g/t. Updates to the Reko Diq5 mineral resources reflect ongoing feasibility study updates, resulting in an attributable measured and indicated mineral resource of 8.3 million tonnes2 of copper at 0.43% with 14 million ounces2 of gold at 0.25g/t, and an attributable inferred mineral resource of 2.2 million tonnes2 of copper at 0.3% with 3.8 million ounces2 of gold at 0.2g/t.

In North America, ongoing growth programs at Turquoise Ridge, Leeville Underground in Carlin and Robertson in Cortez added 1.9 million ounces2 of gold on an attributable basis before annual depletion, effectively replacing more than 80% of annual depletion. This resulted in sustaining attributable proven and probable mineral reserves for the region of 31 million ounces2 at 2.45g/t for 2023. At the same time, attributable gold measured and indicated mineral resources for the region stand at 68 million ounces2 at 2.10g/t, while updated inferred attributable gold resources grew to 18 million ounces2 at 2.1 g/t. Looking forward to 2024, the regional mineral resource base is forecast to be a key driver of future growth. As part of this, a comprehensive evaluation program and dedicated study team will evaluate the strike length of the 100% owned Fourmile deposit7, targeting an update to mineral resources at the end of 2024, which will inform Barrick's decision on commencement of a pre-feasibility study.

    CLP Exchange Rate (USD:CLP) 900 900 900
    EUR Exchange Rate (EUR:USD) 1.10 1.20 1.20


    Barrick's five-year indicative outlook is based on our current operating asset portfolio, sustaining projects in progress and exploration/mineral resource management initiatives in execution. This outlook is based on our current reserves and resources as disclosed in this press release and assumes that we will continue to be able to convert resources into reserves. Additional asset optimization, further exploration growth, new project initiatives and divestitures are not included. For the company's gold and copper segments, and where applicable for a specific region, this indicative outlook is subject to change and assumes the following: new open pit production permitted and commencing at Hemlo in the second half of 2025, allowing three years for permitting and two years for pre-stripping prior to first ore production in 2027; Tongon will enter care and maintenance by 2026; and production from the Zaldívar CuproChlor® Chloride Leach Project (Antofagasta is the operator of Zaldívar).

    Our five-year indicative outlook excludes: production from Fourmile; Pierina and Golden Sunlight, both of which are currently in care and maintenance; and production from long-term greenfield optionality from Donlin, Pascua-Lama, Norte Abierto and Alturas.

    Barrick's ten-year indicative production profile is subject to change and is based on the same assumptions as the current five-year outlook detailed above, except that the subsequent five years of the ten-year outlook assumes attributable production from Fourmile as well as exploration and mineral resource management projects in execution at Nevada Gold Mines and Hemlo.

    Barrick's five-year and ten-year production profile in this press release also assumes the re-start of Porgera, as well as an indicative gold and copper production profile for Reko Diq and an indicative copper production profile for the Lumwana Super Pit expansion, both of which are conceptual in nature.

    Mineral Reserves and Resources Endnotes

  • Mineral reserves (“reserves”) and mineral resources (“resources”) have been estimated as at December 31, 2023 (unless otherwise noted) in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) as required by Canadian securities regulatory authorities. For United States reporting purposes, the SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the Securities and Exchange Act of 1934, as amended (the“Exchange Act”). These amendments became effective February 25, 2019 (the“SEC Modernization Rules”) with compliance required for the first fiscal year beginning on or after January 1, 2021. The SEC Modernization Rules replace the historical property disclosure requirements for mining registrants that were included in SEC Industry Guide 7, which was rescinded from and after the required compliance date of the SEC Modernization Rules. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of“measured”,“indicated” and“inferred” mineral resources. In addition, the SEC has amended its definitions of“proven mineral reserves” and“probable mineral reserves” to be substantially similar to the corresponding Canadian Institute of Mining, Metallurgy and Petroleum definitions, as required by NI 43-101. U.S. investors should understand that“inferred” mineral resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. In addition, U.S. investors are cautioned not to assume that any part or all of Barrick's mineral resources constitute or will be converted into reserves. Mineral resource and mineral reserve estimations have been prepared by employees of Barrick, its joint venture partners or its joint venture operating companies, as applicable, under the supervision of Richard Peattie, Africa and Middle East Mineral Resource Manager, Chad Yuhasz, Latin America & Asia Pacific Mineral Resource Manager and Craig Fiddes, Lead - Resource Modeling, Nevada Gold Mines and reviewed by Simon Bottoms, Barrick's Mineral Resource Management and Evaluation Executive. For 2023, reserves have been estimated based on an assumed gold price of US$1,300 per ounce, an assumed silver price of US$18.00 per ounce, and an assumed copper price of US$3.00 per pound and long-term average exchange rates of 1.30 CAD/US$, except at Tongon, where mineral reserves for 2023 were calculated using $1,500/oz; Hemlo, where mineral reserves for 2023 were calculated using $1,400/oz and at Zaldívar, where mineral reserves for 2023 were calculated using Antofagasta guidance and an updated assumed copper price of US$3.50 per pound. For 2022, reserves were estimated based on an assumed gold price of US$1,300 per ounce, an assumed silver price of US$18.00 per ounce, and an assumed copper price of US$3.00 per pound and long-term average exchange rates of 1.30 CAD/US$, except at Zaldívar, where mineral reserves for 2022 were calculating using Antofagasta guidance and an assumed copper price of US$3.30 per pound. Reserve estimates incorporate current and/or expected mine plans and cost levels at each property. Varying cut-off grades have been used depending on the mine and type of ore contained in the reserves. Barrick's normal data verification procedures have been employed in connection with the calculations. Verification procedures include industry-standard quality control practices. Resources as at December 31, 2023 have been estimated using varying cut-off grades, depending on both the type of mine or project, its maturity and ore types at each property.
  • In confirming our annual reserves for each of our mineral properties, projects, and operations, we conduct a reserve test on December 31 of each year to verify that the future undiscounted cash flow from reserves is positive. The cash flow ignores all sunk costs and only considers future operating and closure expenses as well as any future capital costs.
  • All mineral resource and mineral reserve estimates of tonnes, Au oz, Ag oz and Cu tonnes are reported to the second significant digit.
  • Porgera mineral reserves and mineral resources are reported on a 24.5% interest basis, reflecting Barrick's ownership interest in accordance with the Porgera Project Commencement Agreement (the“Commencement Agreement”) completed on December 22, 2023. The Commencement Agreement provided, among other things, for ownership of Porgera to be held in a new joint venture called New Porgera Limited, which is owned 51% by Papua New Guinea stakeholders and 49% by a Barrick affiliate, Porgera (Jersey) Limited (“PJL”). PJL is jointly owned on a 50/50 basis by Barrick and Zijin Mining Group and accordingly Barrick has a 24.5% ownership interest in the Porgera mine. Barrick Niugini Limited has retained operatorship of the mine. Barrick expects to include Porgera in the Company's 2024 guidance when it reports its full year and fourth quarter results on February 14, 2024. For additional information, see Barrick's press release entitled“Recommissioning Starts as Porgera Prepares to Resume Operations in Q1 2024” dated December 22, 2023.
  • Reko Diq mineral resources are reported on a 50% interest basis, reflecting Barrick's ownership interest following the completion of the transaction allowing for the reconstitution of the project on December 15, 2022. This completed the process that began earlier in 2022 following the conclusion of a framework agreement among the Governments of Pakistan and Balochistan province, Barrick and Antofagasta plc, which provided a path for the development of the project under a reconstituted structure. The reconstituted project is held 50% by Barrick and 50% by Pakistani stakeholders. Barrick is the operator of the project. For additional information, see pages 41-42 of Barrick's Third Quarter Report 2023.
  • 2023 polymetallic mineral resources and mineral reserves are estimated using the combined value of gold, copper and silver and accordingly are reported as gold, copper and silver mineral resources and mineral reserves.
  • For 2023, mineral resources have been estimated based on an assumed gold price of US$1,700 per ounce, an assumed silver price of US$21.00 per ounce, and an assumed copper price of US$4.00 per pound and long-term average exchange rates of 1.30 CAD/US$, except Zaldívar, where mineral resources for 2023 were calculated using Antofagasta guidance and an assumed copper price of US$4.20 per pound. For 2022, mineral resources were estimated based on an assumed gold price of US$1,300 per ounce, an assumed silver price of US$21.00 per ounce, and an assumed copper price of US$3.75 per pound and long-term average exchange rates of 1.30 CAD/US$, except at Zaldívar, where mineral resources for 2022 were calculated using Antofagasta guidance and an assumed copper price of US$3.75
  • All mineral resources are reported inclusive of mineral reserves.
  • Mineral resources which are not mineral reserves do not have demonstrated economic viability.
  • All measured and indicated mineral resource estimates of grade and all proven and probable mineral reserve estimates of grade for Au g/t, Ag g/t and Cu % are reported to two decimal places.
  • All inferred mineral resource estimates of grade for Au g/t, Ag g/t and Cu % are reported to one decimal place.
