TORONTO, Feb. 09, 2023 (GLOBE NEWSWIRE) — Barrick Gold Corporation (NYSE:GOLD)(TSX:ABX) grew attributable proven and probable gold mineral reserves by 6.7 million ounces net of depletion in 2022, while maintaining grade despite an increase in the reserve price assumption. Reported at $1,300/oz1, attributable proven and probable mineral reserves now stand at 76 million ounces2 at 1.67g/t, increasing from 69 million ounces3 at 1.71g/t reported at $1,200/oz1 in 2021. Led by Pueblo Viejo and the Africa & Middle East region, Barrick has now delivered a second consecutive year of gold reserve growth over and above annual depletion, with nearly 12 million ounces2 of attributable proven and probable reserve gains in 2022 before depletion.
Successful exploration at both the Lumwana and Jabal Sayid mines drove the growth of attributable proven and probable copper reserves by 640 million pounds2, notwithstanding an increase in the annual reserve price assumption to $3.00/lb1. As a result, Barrick replaced 103% of annual global depletion at consistent quality, effectively maintaining attributable proven and probable copper mineral reserves of 12 billion pounds2 at 0.38% in 2022.
Total attributable gold mineral resources grew by nearly 10% relative to 2021, and total attributable copper mineral resources more than doubled, growing by 124% year over year, both net of annual depletion. This growth was driven by the successful completion of a preliminary economic assessment supporting the Lumwana Super Pit expansion, and the incorporation of Reko Diq following the reconstitution of the project in December 2022. Attributable measured and indicated gold resources for 2022 stand at 180 million ounces2 at 1.07g/t, with a further 42 million ounces2 at 0.8g/t of inferred resources. Attributable measured and indicated copper resources for 2022 stand at 44 billion pounds2 at 0.39%, with a further 15 billion pounds2 at 0.4% of inferred resources. Mineral resources are reported inclusive of reserves and for 2022, are based on a gold price of $1,700/oz1 and a copper price of $3.75/lb1.
President and chief executive Mark Bristow said in a sector of diminishing reserves and resources, Barrick’s strategy of investing in organic growth through exploration and mineral resource management has replenished and delivered significant value within the company’s asset base.
“While we continue to evaluate all new opportunities against our strategic filters, we have always believed that finding our ounces is better than buying them, and this year’s resource and reserve statement showcases the unmatched potential of our organic growth pipeline,” said Bristow.
Mineral Resource Management and Evaluation Executive Simon Bottoms stated that basing the company’s reserve calculations at a price of $1,300/oz for gold1 and $3.00/lb for copper1 underpins our focus on quality assets.
“The substantial growth in our mineral resources lays the long-term foundation to potentially grow our current attributable production profile of approximately 5.5 million gold equivalent ounces4 per year to approximately 6.5 million gold equivalent ounces4 per year by the end of this decade, which would include production from Reko Diq and the Lumwana Super Pit,” said Bottoms.
In Africa, the Tier One5 operations led the growth in 2022 reserves, where Kibali completed an updated underground feasibility study on the 11000 lode, delivering a 0.62 million ounce2 increase in attributable proven and probable reserves before depletion. Loulo-Gounkoto also delivered strong results replacing reserve depletion, which further extended the mine life by another year. Moving to Tanzania, the focus on underground expansion at Gokona in North Mara has delivered a 0.44 million ounce2 increase in 2022 attributable proven and probable reserves before depletion.
The Lumwana copper mineral resource base grew by 89%, net of depletion, relative to 2021. This follows the completion of the preliminary economic assessment on the Super Pit expansion that demonstrates strong potential for a Tier One Copper Asset5 and provides the basis for the ongoing pre-feasibility study.
Within the Latin America & Asia Pacific region, Pueblo Viejo completed a pre-feasibility study for the new Naranjo tailings storage facility (TSF), adding 6.5 million ounces of attributable proven and probable reserves2,6, net of depletion, and extending the minelife beyond 2040. As a result, 2022 attributable proven and probable gold reserves for the region have increased to 27 million ounces2 at 0.97g/t from 21 million ounces3 at 0.83g/t in 2021.
The reconstitution of the Reko Diq project added an attributable 18 billion pounds of copper2 at 0.44% with 15 million ounces gold2 at 0.26g/t to indicated resources, and an attributable 4.6 billion pounds of copper2 at 0.4% with 3.7 million ounces gold2 at 0.2g/t to inferred resources. These mineral resources reflect only three porphyries (H13, H14, H15) as well as the Tanjeel deposit within the cluster of Western Porphyries. Alongside the ongoing feasibility study update, the team is also planning to evaluate further known porphyry occurrences within the mining lease area.
In North America, the completion of pre-feasibility studies for the Robertson open pit project at Cortez, as well as a new pushback in the Hemlo open pit were significant contributors to reserve growth. As a result, Robertson’s maiden attributable proven and probable gold reserves are estimated at 1.0 million ounces2 at 0.46g/t. This represents a milestone for Cortez as a key source of oxide mill feed in the mine plan. Similarly, the new Hemlo open pit pushback is expected to commence in 2027 adding 0.86 million ounces2 of gold at 1.49g/t to probable reserves. Combined with other updates across the region, this results in the growth of North America attributable proven and probable reserves by 1.8 million ounces2 before depletion, with proven and probable attributable reserves for the region now estimated at 31 million ounces2 at 2.54g/t. At the same time, attributable gold mineral resources also grew significantly, supporting future potential reserve growth in line with our strategy to fully replace depletion for the region within a five-year period. Measured and indicated attributable gold resources increased by 2.8 million ounces2 to 73 million ounces2 at 2.16 g/t, from 70 million ounces3 at 2.22 g/t in 2021. Inferred attributable gold resources also increased to 17 million ounces2 at 1.8 g/t, from 16 million ounces3 at 2.0 g/t in 2021. Underground resource extension drilling at both Goldstrike and Leeville in Carlin were key drivers of this organic resource growth, as well as successful resource definition drilling at Goldrush and Robertson in Cortez, all of which support the potential for future reserve growth in this region.

| CLP Exchange Rate (USD:CLP) | 900 | 900 | 900 |
| EUR Exchange Rate (EUR:USD) | 1.20 | 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 group 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; production from the proposed Pueblo Viejo plant expansion and tailings project starting in 2023, in-line with guidance; 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, 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, 2022 (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, Manager – Resource Modeling, Nevada Gold Mines and reviewed by Simon Bottoms, Barrick’s Mineral Resource Management and Evaluation Executive. For 2022, 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 Zaldívar, where mineral reserves for 2022 were calculated using Antofagasta guidance and an assumed copper price of $3.10 per pound. For 2021, reserves were estimated based on an assumed gold price of US$1,200 per ounce, an assumed silver price of US$16.50 per ounce, and an assumed copper price of US$2.75 per pound and long-term average exchange rates of 1.30 CAD/US$., except at Zaldívar, where mineral reserves for 2021 were calculated using Antofagasta guidance and an assumed copper price of $3.10 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, 2022 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 lb are reported to the second significant digit.
- Porgera mineral reserves and mineral resources are reported on a 24.5% interest basis, reflecting Barrick’s expected ownership interest following the implementation of the binding February 3, 2022 Commencement Agreement . The Commencement Agreement provides, among other things, for ownership of Porgera to be held in a new joint venture owned 51% by Papua New Guinea (“PNG”) stakeholders and 49% by Barrick Niugini Limited (“BNL”) or an affiliate. BNL is jointly owned on a 50/50 basis by Barrick and Zijin Mining Group and will retain operatorship of the mine under the terms of the Commencement Agreement. Efforts are ongoing to execute the remaining definitive agreements to implement the Commencement Agreement and finalize a timeline for the reopening of the Porgera mine and resumption of full mine operations. For additional information, see pages 8-9 of Barrick’s Third Quarter Report 2022.
- Cortez underground includes 21 million tonnes at 7.27g/t for 4.9 million ounces of probable reserves, 29 million tonnes at 6.49g/t for 6.1 million ounces of indicated resources and 15 million tonnes at 5.9g/t for 2.8 million ounces of inferred resources related to Goldrush. As noted in endnote 9, mineral resources are reported on an inclusive basis.
- 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, 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 Barrick’s press release entitled “Massive Reko Diq Project Gets All Clear, Barrick Starts Updating Plans” dated December 15, 2022.
- 2022 polymetallic mineral resources and mineral reserves are estimated using the combined value of gold, copper & silver and accordingly are reported as gold, copper and silver mineral resources and mineral reserves.
- Mineral resources which are not mineral reserves do not have demonstrated economic viability.
- Mineral resources are reported inclusive of mineral reserves.
- 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.
