Pan American Silver Reports Mineral Reserves and Mineral Resources as at June 30, 2024

Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) ("Pan American" or the "Company") reports its estimated mineral reserves and mineral resources as at June 30, 2024. Proven and probable mineral reserves are estimated to contain approximately 468.0 million ounces of silver and 6.9 million ounces of gold. Measured and indicated ("M&I") mineral resources (excluding proven and probable ("P&P") reserves) are estimated to total approximately 1,148.0 million ounces of silver and 15.5 million ounces of gold. Inferred mineral resources are estimated to total approximately 366.0 million ounces of silver and 9.4 million ounces of gold. The updated mineral reserves and mineral resources estimates are reported net of the sales of the MARA, Agua de la Falda and Morococha properties, as announced in the Company's news release dated July 31, 2023. The divestment of these non-core, non-producing assets is largely responsible for a decrease in mineral reserves and mineral resources compared to 2023.

“Our exploration efforts have successfully replaced mine production and expanded mineral reserves at Jacobina, La Colorada, Huaron and Minera Florida. In addition, infill and extensional drilling at the Jacobina mine has increased inferred mineral resources by over 1.2 million ounces of gold, highlighting the significant exploration potential of the deposit and the opportunity to replace mineral resources and mineral reserves in the future,” said Christopher Emerson, Pan American’s Vice President of Exploration and Geology. “At the La Colorada Skarn project, estimated indicated mineral resources have grown substantially to 309 million ounces of silver due to higher tonnage and higher grades, with the inferred mineral resource now estimated at 59 million ounces of silver. Zinc and lead contained within the skarn deposit have also increased since our last resource update.”

In 2024, Pan American plans to complete over 360,000 metres of drilling across its portfolio of mines, focused on near-mine exploration for mineral reserve replacement.

Mineral reserve and mineral resource highlights for the 12-months ended June 30, 2024:

• The successful divestment of non-core, non-producing properties - MARA, Morococha and Agua de la Falda - in 2023 reduced the consolidated P&P mineral reserves by 89.9 million ounces of silver and 5.2 million ounces of gold. After adjusting for a full year of production, the significant exploration success at many of our operations and other parameters, the consolidated mineral reserves at June 30, 2024, are estimated to total 468.0 million ounces of silver and 5.2 million ounces of gold.
• Consolidated M&I silver mineral resources increased from an estimated 959.0 million ounces to an estimated 1,148.0 million ounces. The increase in M&I silver mineral resources is mainly due to the increase in indicated resources at the La Colorada Skarn project more than offsetting the sales of MARA and Morococha. Consolidated M&I gold mineral resources decreased from an estimated 17.5 million ounces to an estimated 15.5 million ounces, largely due to the sales of the MARA and Agua de la Falda properties.
• At the La Colorada Skarn project, estimated indicated mineral resources significantly increased to 308.7 million ounces of contained silver with higher tonnage, higher silver and base metal grades, and improved geological confidence.
• At Jacobina, exploration more than replaced mine production with new mineral reserves, marking the eighth consecutive year of full replacement of production. New gold inferred mineral resources estimated at over 1.2 million ounces were also added, including 495 thousand ounces at Maricota, a new zone north of Morro do Cuscuz. See the Company's news releases dated June 17, 2024 and December 5, 2023, for further information on Maricota.
• At El Peñon, mineral resources and mineral reserves were added to the southeast of the current mining zones in major veins like Pampa Sur and Pampa Campamento, as well as in silver rich structures like Tostado Sur and others. Future exploration will continue to target converting the large inferred mineral resource to mineral reserves and to discovering new veins on the mine's extensive land position.
• At La Colorada, the eastward extensions of the veins, described in previous news releases, contributed to a net addition to silver P&P mineral reserves.
• At Minera Florida, 103.7 thousand ounces of P&P gold mineral reserves and 864 thousand ounces of P&P silver mineral reserves were added, more than replacing mine production.
• At Huaron, P&P silver mineral reserves increased by 1.7 million ounces, more than replacing mine production, with the Horizonte zone alone adding 2.7 million ounces of new P&P silver mineral reserves.
• At Timmins, exploration has been focused on the Whitney joint venture project, with more than 20,500 metres of drilling completed over the 2021 to 2023 period, contributing to an updated estimate for indicated gold mineral resources of 93.6 thousand ounces and inferred gold mineral resources of 574.0 thousand ounces (based on a 100% interest). Pan American is now focused on further exploratory and confirmation drilling of the project. See the December 5, 2023 news release for more information on the Whitney project.

A detailed summary of the silver and gold mineral reserves and mineral resources as at June 30, 2024 is provided in the tables at the end of this news release.

LA COLORADA SKARN MINERAL RESOURCE UPDATE

Approximately 73,000 metres of exploration and infill drilling have been completed since the last mineral resource update, including high-grade intercepts reported in previous news releases. The drilling has resulted in a significant increase in estimated mineral resources and higher silver and base metal grades. It also improved a large portion of mineral resources from the inferred category to indicated. The tables below illustrate the improvements and the highlights include:

• A 53% increase in indicated mineral resources to an estimated 265.4 million tonnes.
• Improvement in silver, zinc and lead grades by 10%, 2% and 4%, respectively, for the indicated mineral resource category.
• A 69% increase in contained silver to 308.7 million ounces in indicated mineral resources. Contained silver in inferred mineral resources is estimated at 58.6 million ounces.
• A 56% increase in contained zinc to 7.6 million tonnes and a 60% increase in contained lead to 3.6 million tonnes in indicated mineral resources.
• Addition of 125.5 million ounces of silver, 2.7 million tonnes of zinc and 1.4 million tonnes of lead to indicated mineral resources.

Exploration and resource infill drilling is ongoing with additional drill rigs completing condemnation and hydrogeological work. Engineering work continues with geotechnical studies required for sub level caving ("SLC") and reviewing the updated mineral resource and mining shapes to optimize mineral extraction.

Next steps include further infill drilling, additional analysis of alternative mining methods, optimizing throughputs, preparing capital and operating cost estimates, as well as advancing discussions with potential project partners.

La Colorada Skarn Estimated Mineral Resource as at June 30, 2024

Classification	Tonnes (millions)	Zn (%)	Pb (%)	Ag (g/t)
Indicated	265.4	2.85	1.37	36
Inferred	61.7	2.55	0.95	30

Notes:

1. The effective date of the mineral resources estimate is June 30, 2024.
2. Estimation and reporting of mineral resources were carried out in accordance with Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) guidelines.
3. Mineral resources have been classified into indicated and inferred confidence categories.
4. Mineral resources have reasonable prospects for eventual economic extraction demonstrating sufficient spatial continuity of mineralization constrained within a potentially mineable shape. Mineral resources that are not mineral reserves do not have demonstrated economic viability. No mineral reserves are reported at this time for the La Colorada Skarn project.
5. Prices used to report mineral resources were: $22.00 per ounce of silver, $2,800 per tonne of zinc and $2,200 per tonne of lead.
6. An estimated NSR (in US$/t) was calculated using metallurgical recoveries of 84.9% Ag, 84.3% Pb and 93.7% Zn with mineral concentrate qualities of 61% Pb in lead concentrate and 59% Zn in zinc concentrate, obtained from metallurgical testing. Estimates for transport, payability and refining/selling costs, based on experience and long-term views of the marketing, treatment and refining of these types of mineral concentrates, were included.
7. Reasonable prospects for eventual economic extraction were assessed by determining the total in-situ tonnes and metal grades constrained inside volumes that are based on a SLC mining method considering operating and sustaining capital cost estimates of $45/t. To determine the constraining SLC shapes, an initial elevated cutoff value of $50/t NSR was applied. Then geotechnical, geometry and caving rules were applied to ensure practical mining shapes were achieved. The resulting constraining shapes were then considered to be practical mining outlines. The tonnes and grades are inclusive of the must-take low grade material within the volume. No other mining recovery, ring recovery, dilution or mineral losses have been applied.
8. This mineral resource estimate was prepared under the supervision of, or was reviewed by, Christopher Emerson, FAusIMM, Vice President Exploration and Geology, who is a Qualified Person as that term is defined in NI 43-101.
9. Grades are shown as contained metal before mill recoveries are applied. The Company has undertaken a verification process with respect to the data disclosed in this news release.
10. A total of 376 diamond drill holes with a total length of 314,930 metres were used in the geological interpretation and resource estimate. Several old historic drill holes were included in the modeling. Drilling of the La Colorada Skarn deposit has been completed from both surface and underground drill platforms.
11. All drill hole samples used in the mineral resource estimate have been previously reported in news releases dated October 23, 2018, February 21, 2019, May 8, 2019, August 1, 2019, October 30, 2019, February 13, 2020, August 4, 2020, May 12, 2021, November 10, 2021, February 24, 2022, May 9, 2022, November 1, 2022, May 2, 2023, December 5, 2023, and April 7, 2024.

General Notes with Respect to Technical Information

All mineral reserves and mineral resources have been estimated in accordance with the CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Standards") and reported in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). Mineral resources are reported exclusives of mineral reserves.

Pan American does not expect these mineral reserve and mineral resource estimates to be materially affected by metallurgical, environmental, permitting, legal, taxation, socio-economic, political, and marketing or other relevant issues.

The Company has undertaken a verification process with respect to the data disclosed in this news release. The mineral resources and mineral reserves databases comprising drilling and, in some cases, surface and underground sampling, have been compiled at each of the Pan American mine sites by the qualified staff. All the assay data used in the resource evaluation provided by each of the mines has been subjected to the industry standard quality assurance and quality control ("QA/QC") program including the submission of certified standards, blanks, and duplicate samples. The results are reviewed monthly by management. The results of the QA/QC samples submitted for the resource databases demonstrate acceptable accuracy and precision. The Qualified Person is of the opinion that the sample preparation, analytical, and security procedures followed for the samples are sufficient and reliable for the purpose of these mineral resource and mineral reserve estimates. Pan American is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data reported herein.

Quantities and grades of contained metal are shown before metallurgical recoveries.

Technical information contained in this news release with respect to Pan American has been reviewed and approved by Christopher Emerson, FAusIMM., Vice President of Exploration and Geology, and Martin Wafforn, P.Eng., Senior Vice President Technical Services and Process Optimization, who are each Qualified Persons for the purposes of NI 43-101.

Pan American Silver Corp. is authorized by The Association of Professional Engineers and Geoscientists of the Province of British Columbia to engage in Reserved Practice under Permit to Practice number 1001470.

Cautionary Note Regarding Forward-Looking Statements and Information

Certain of the statements and information in this news release constitute “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 and “forward-looking information” within the meaning of applicable Canadian provincial securities laws. All statements, other than statements of historical fact, are forward-looking statements or information. Forward-looking statements or information in this news release relate to, among other things: estimated mineral reserve and mineral resource information; estimated mine life and any anticipated changes related thereto; the extent of, and success related to any future exploration or development programs; expectations that metallurgical, environmental, permitting, legal, title, taxation, socio-economic, political, marketing or other issues will not materially affect estimates of mineral reserves and mineral resources; expectations regarding planned drilling in 2024, including that it will be focused on near-mine exploration; expectations regarding mineral reserve replacement; and expectations with respect to future work to be conducted at the La Colorada Skarn project.

These forward-looking statements and information reflect the Company’s current views with respect to future events and are necessarily based upon a number of assumptions that, while considered reasonable by the Company, are inherently subject to significant operational, business, economic and regulatory uncertainties and contingencies. These assumptions include: the accuracy of our mineral reserve and mineral resource estimates and the assumptions upon which they are based; ore grades and recoveries are as anticipated; prices for silver, gold, and base metals remaining as estimated; currency exchange rates remaining as estimated; capital, decommissioning and reclamation estimates; prices for energy inputs, labour, materials, supplies and services (including transportation); all necessary permits, licenses and regulatory approvals for our operations are received in a timely manner; and our ability to comply with environmental, health and safety laws. The foregoing list of assumptions is not exhaustive.

The Company cautions the reader that forward-looking statements and information involve known and unknown risks, uncertainties and other factors that may cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements or information contained in this news release and the Company has made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: fluctuations in silver, gold and base metal prices; fluctuations in prices for energy inputs, labour, materials, supplies and services (including transportation); fluctuations in currency markets (such as the PEN, MXN, ARS, BOB, CLP, BRL, GTQ and CAD versus the USD); operational risks and hazards inherent with the business of mining (including environmental accidents and hazards, industrial accidents, equipment breakdown, unusual or unexpected geological or structural formations, cave-ins, flooding and severe weather); employee relations; relationships with, and claims by, local communities and indigenous populations; our ability to obtain all necessary permits, licenses and regulatory approvals in a timely manner; changes in laws, regulations and government practices in the jurisdictions where we operate, including environmental, export and import laws and regulations; legal restrictions relating to mining; risks relating to expropriation; diminishing quantities or grades of mineral reserves as properties are mined; increased competition in the mining industry for equipment and qualified personnel; and those factors identified under the caption “Risks Related to Pan American’s Business” in the Company’s most recent form 40-F and Annual Information Form filed with the United States Securities and Exchange Commission (the “SEC”) and Canadian provincial securities regulatory authorities, respectively. Although the Company has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, described or intended. Investors are cautioned against undue reliance on forward-looking statements or information. Forward-looking statements and information are designed to help readers understand management’s current views of our near and longer term prospects and may not be appropriate for other purposes. The Company does not intend, nor does it assume any obligation to update or revise forward-looking statements or information, whether as a result of new information, changes in assumptions, future events or otherwise, except to the extent required by applicable law.

Cautionary Note to US Investors Regarding References to Mineral Reserves and Mineral Resources

Unless otherwise indicated, all reserve and resource estimates included in this news release have been prepared in accordance with NI 43-101 and the CIM Standards. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the mineral property disclosure requirements of the SEC (the “U.S. Rules”), and reserve and resource information included herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, this news release uses the terms “measured resources,” “indicated resources” and “inferred resources” as defined in accordance with NI 43-101 and the CIM Standards. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms under the U.S. Rules are “substantially similar” to the standards under NI 43-101 and CIM Standards, there are differences in the definitions under the U.S. Rules and CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the U.S. Rules.
