"In 2025, Newmont maintained its position of having the industry's largest gold reserve base, declaring 118 million ounces of reserves, representing decades of production life with meaningful upside," said Natascha Viljoen, Newmont's President and Chief Executive Officer. "Through the disciplined application of technical rigor in our leading exploration program, we remain focused on extending mine life, discovering new opportunities, and unlocking value across our world-class portfolio of operations and projects."

2025 Reserves & Resources Highlights

• The gold industry's largest reserve base with 118.2 million attributable ounces¹
• Changes since 2024 are mainly driven by divestments (8.6 million ounces), followed by depletion from mining, reclassification of the Yanacocha Sulfides project reserves to resources, and cost escalation assumptions, offset by an increased gold price assumption, resource conversion and other positive revisions at Brucejack, Tanami, Lihir, Ahafo North and Ahafo South
• Gold reserves are determined based on a gold price of $2,000 per ounce following the annual pricing review, more than 20 percent below the three-year trailing average price and well below the current spot price
• Newmont benefits from a premier operating asset base with gold reserve life of ten years or more at Lihir, Cadia, Tanami, Boddington, Ahafo North, Merian, Cerro Negro, Brucejack, Nevada Gold Mines (NGM), and Pueblo Viejo further enhanced by a broader portfolio and organic project pipeline
• Measured & Indicated Gold Mineral Resources² of 88.1 million attributable ounces and Inferred Resources of 60.6 million attributable ounces, determined based on a gold price of $2,300 per ounce
• Significant exposure to other metals including 12.5 million attributable tonnes of copper reserves, 13.1 million attributable tonnes of Measured & Indicated copper resources and 5.6 million attributable tonnes of Inferred copper resources, along with 442 million ounces of silver reserves, 508 million ounces of Measured & Indicated silver resources and 126 million ounces of Inferred silver resources
• Additional exposure to other metals including lead, zinc and molybdenum

Newmont's reserve base is a key differentiator with an operating reserve life of more than ten years at eight managed sites and two non-managed joint ventures, anchored in favorable mining jurisdictions along with significant upside potential from a robust organic project pipeline.

PROVEN & PROBABLE GOLD RESERVES

For 2025, Newmont reported 118.2 million attributable ounces of gold reserves compared to the prior year total of 134.1 million attributable ounces. Divestment of assets accounted for 8.6 million ounces of this reduction³, followed by depletion from mining of 7.2 million ounces, net negative revisions of 5.6 million ounces (primarily from Yanacocha Sulfides reclassified to resource) and cost escalation assumption impacts of 3.1 million ounces, offset by increases from price related revisions of 6.6 million ounces, as well as the addition of 2.0 million ounces from conversion of resources and other additions primarily at Brucejack (+0.7 million ounces) and Lihir (+0.5 million ounces).

Managed Assets

• Brucejack reserves increased 1.0 million ounces to 2.9 million ounces, primarily due to conversion of resources of 0.7 million, positive net revisions of 0.3 million following favorable drilling results and a favorable price impact of 0.2 million ounces net of cost escalation assumptions, offsetting depletion of 0.2 million ounces
• Merian reserves increased 0.4 million ounces to 4.5 million ounces, primarily due to favorable price related revisions of 0.8 million ounces, more than offsetting negative net revisions of 0.2 million ounces and depletion of 0.2 million ounces
• Lihir reserves increased 0.2 million ounces to 16.0 million ounces, primarily due to favorable price impacts of 0.8 million ounces and conversion from resources through infill drilling of 0.5 million ounces, partially offset by net negative revisions of 0.3 million ounces offsetting depletion of 0.8 million ounces
• Tanami reserves increased 0.2 million ounces to 5.3 million ounces, primarily due to favorable price impacts, net of cost escalation of 0.3 million ounces, additions from net positive revisions of 0.2 million ounces and resource conversion from infill drilling of 0.1 million ounces, more than offsetting depletion of 0.4 million ounces
• Ahafo North reserves increased 0.1 million ounces to 4.7 million ounces, primarily due to additions from resources through updated mine designs of 0.2 million ounces, partially offset by depletion of 0.1 million ounces
• Red Chris reserves decreased 0.1 million ounces to 3.6 million ounces, primarily due to depletion of 0.1 million ounces
• Cerro Negro reserves decreased 0.2 million ounces to 3.0 million ounces, primarily due to depletion of 0.2 million ounces and negative net revisions of 0.1 million ounces, partially offset by 0.1 million ounces of conversions from resources with infill drilling
• Ahafo South reserves decreased 0.5 million ounces to 4.1 million ounces, primarily due to the depletion of 0.8 million ounces, partially offset by 0.2 million ounces added at the Apensu South open pit and positive price impacts of 0.1 million ounces
• Boddington reserves decreased 0.6 million ounces to 10.2 million ounces, primarily due to depletion of 0.6 million ounces and negative net revisions of 0.1 million ounces, partially offset by favorable price related revisions 0.1 million ounces net of cost escalation assumptions
• Cadia reserves decreased 0.6 million ounces to 13.5 million ounces, primarily due to depletion of 0.5 million ounces
• Peñasquito reserves decreased 0.9 million ounces to 3.2 million ounces, primarily due to depletion of 0.8 million ounces along with negative net revisions from a block model update of 0.2 million ounces partially offset by favorable price impact of 0.1 million ounces
• Yanacocha reserves decreased 4.8 million ounces to 0.5 million ounces, primarily due to the reclassification of 4.5 million ounces of reserves relating to the Yanacocha Sulfides project to resources, allowing Newmont to prioritize other opportunities at site and continue advancing closure activities in non-operating areas

Non-Managed Assets

• Newmont's 38.5 percent interest in Nevada Gold Mines represented 17.4 million attributable ounces of gold reserves at year end, compared to 17.9 million ounces at the end of 2024
• Newmont's 40 percent interest in Pueblo Viejo represented 8.2 million attributable ounces of gold reserves at year end with no change from 2024

Newmont's gold grade reserve remained unchanged at 0.94 grams per tonne year over year when adjusted for the divested assets.

GOLD RESOURCES⁴⁵

At the end of 2025, Newmont reported Measured and Indicated Gold Mineral Resources of 88.1 million attributable ounces, an 11 percent decrease from the prior year total of 99.4 million attributable ounces. Inferred Gold Mineral Resources totaled 60.6 million attributable ounces, a 14 percent decrease from the prior year total of 70.6 million attributable ounces. The main driver of lower resources is 14.6 million ounces removed from assets divested in 2025⁶, together with net negative revisions, net resource conversions to reserves, and updated cost assumptions; partially offset by the resource increases from price assumption related revisions, as well as additions.

Notable Changes⁷

• Cadia resources decreased by 8.5 million ounces (44 percent) to 11.0 million ounces, primarily driven by 5.7 million ounces of net negative revisions related to a geotechnical standoff from the in-pit tailings facility as well as block model updates and changes to inferred resource classifications as a consequence of an updated drill spacing study. An additional 3.0 million ounces of negative impact from higher cost expectations for future caves net of benefits from higher price assumptions
• Namosi resources of 5.0 million ounces were removed from resources as Newmont further evaluates the project
• Yanacocha resources increased by 4.3 million ounces, primarily driven by 4.5 million ounces reclassified from reserves from Yanacocha Sulfides, aligned with Newmont's decision to indefinitely defer the project
• Ahafo South resources increased 45 percent to 7.4 million ounces, primarily driven by 1.7 million ounces of resource additions largely at Apensu underground

Newmont's Measured and Indicated Gold Mineral Resource grade decreased to 0.58 grams per tonne compared to 0.59 grams per tonne in the prior year. Inferred Gold Mineral Resource increased to 0.9 grams per tonne compared to 0.6 grams per tonne in the prior year, largely due to the removal of inferred resources from Namosi and assets divested.

OTHER METALS

Copper reserves decreased slightly to 12.5 million tonnes from 13.5 million tonnes in the prior year, primarily due to reclassification of the Yanacocha Sulfides project to resources. Measured and Indicated copper resources decreased to 13.1 million tonnes from 14.1 million tonnes. Inferred copper resources decreased to 5.6 million tonnes from 11.0 million tonnes driven almost entirely by the removal of Namosi.

Silver reserves decreased to 442 million ounces compared to 530 million ounces in the prior year, primarily due to the reclassification of the Yanacocha Sulfides project to resources and depletion at Peñasquito. Measured and Indicated silver resources increased to 508 million ounces from 469 million ounces in the prior year while inferred silver resources increased to 126 million ounces from 113 million ounces in the prior year; both due to the reclassification of the Yanacocha Sulfides projects.

Lead reserves decreased slightly to 0.7 million tonnes from 0.8 million tonnes primarily due to depletion. Measured and Indicated lead resources were unchanged at 0.5 million tonnes. Zinc reserves decreased to 1.5 million tonnes from 1.7 million tonnes primarily due to depletion. Measured and Indicated zinc resources increased to 1.4 million tonnes from 1.2 million tonnes.

Molybdenum reserves were unchanged at 0.2 million tonnes. Measured and Indicated molybdenum resources remained unchanged at 0.1 million tonnes.

EXPLORATION OUTLOOK

Newmont's attributable exploration expenditure for managed operations is expected to be approximately $205 million in 2026 with 80 percent of total exploration investment dedicated to near-mine expansion programs and brownfields with the remaining 20 percent allocated to the advancement of greenfield projects.

Additionally, Newmont's share of exploration investment for its non-managed operations is expected to be approximately $35 million, for a total consolidated exploration expense outlook of $240 million for 2026.

Newmont expects to invest the largest proportion of exploration funds in prospective targets at Merian, Cerro Negro, and Ahafo South.

UPDATED GOLD PRICE FOR MINERAL RESERVES AND MINERAL RESOURCES

As part of the annual Mineral Reserves and Mineral Resources update, Newmont assesses the metal price assumptions used for the calculation of year-end reserves and resources.

In line with market conditions, Newmont has increased its reserves gold price assumption by 18 percent to $2,000 per ounce from $1,700 per ounce in 2024; which is less than 60 percent of the 2025 average realized gold price. Newmont's updated reserves gold price is approximately 23 percent lower than the three-year trailing gold price average of $2,586 per ounce. Historically, over the last ten years (2015 - 2024), Newmont has assumed a reserve price approximately 13 percent below the three year trailing average. Consistent with Newmont's historical approach, the resources gold price has been calibrated higher than reserves to allow identification of the optimum areas to further expand the life of its assets and to target where additional drilling and study work is required at its operating mines. For 2025, mineral resources are based on a $2,300 per ounce.

Newmont's robust internal processes and proven track record of responsibly and rigorously defining reserves and resources will continue to support the development of its world-class portfolio and organic project pipeline.

GOLD RESERVE SENSITIVITY

A $100 increase in gold price would result in an approximate 5 percent increase in gold reserves while a $100 decrease in gold price would result in an approximate 2 percent decrease in gold reserves. These sensitivities assume an oil price of $75 per barrel (WTI), Australian dollar exchange rate of $0.70 and Canadian dollar exchange rate of $0.75. These sensitivities assume all other inputs remain equal, including all cost and capital assumptions, which may also have a material impact on these approximate estimates.

RESERVE AND RESOURCE TABLES

Proven and probable reserves are based on extensive drilling, sampling, mine modeling and metallurgical testing from which Newmont determined economic feasibility. The reference point for mineral reserves is the point of delivery to the process plant. Metal price assumptions, adjusted for Newmont's exchange rate assumption, are based on considering such factors as market forecasts, industry consensus and management estimates. The price sensitivity of reserves depends upon several factors including grade, metallurgical recovery, operating cost, waste-to-ore ratio and ore type. Metallurgical recovery rates vary depending on the metallurgical properties of each deposit and the production process used. The reserve tables below list the average estimated in-situ metallurgical recovery rate for each deposit, which takes into account the relevant processing methods. The cut-off grade, or lowest grade of mineralization considered economic to process, varies between deposits depending upon prevailing economic conditions, mineability of the deposit, by-products, amenability of the ore to gold, copper, silver, lead, zinc or molybdenum extraction and type of milling or leaching facilities available. Reserve estimates may have non-material differences in comparison to our joint venture partners due to differences in classification and rounding methodology.

The proven and probable reserve figures presented herein are estimates based on information available at the time of calculation. No assurance can be given that the indicated levels of recovery of gold, copper, silver, lead, zinc and molybdenum will be realized. Ounces of gold or silver or tonnes of copper, lead, zinc or molybdenum included in the proven and probable reserves are those contained prior to losses during metallurgical treatment. Reserve estimates may require revision based on actual production. Market fluctuations in the price of gold, copper, silver, lead, zinc and molybdenum, as well as increased production costs or reduced metallurgical recovery rates, could render certain proven and probable reserves containing higher cost reserves uneconomic to exploit and might result in a reduction of reserves.

The measured, indicated, and inferred resource figures presented herein are estimates based on information available at the time of calculation and are exclusive of reserves. A "mineral resource" is a concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, grade, or quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling. The reference point for mineral resources is in situ. Mineral resources are sub-divided, in order of increasing geological confidence, into inferred, indicated and measured categories. Ounces of gold and silver or tonnes of copper, zinc, lead and molybdenum included in the measured, indicated and inferred resources are those contained prior to losses during metallurgical treatment. The terms "measured resource," "indicated resource," and "inferred resource" mean that part of a mineral resource for which quantity and grade or quality are estimated on the basis of geological evidence and sampling that is considered to be comprehensive, adequate, or limited, respectively. Market fluctuations in the price of gold, silver, copper, zinc, lead and molybdenum as well as increased production costs or reduced metallurgical recovery rates, could change future estimates of resources.

Newmont publishes reserves annually, and will recalculate reserves at December 31, 2026, taking into account metal prices, changes, if any, to future production and capital costs, divestments and conversion to reserves, as well as any acquisitions and additions during 2026.
