**Pan American Silver Reports Discovery of Multiple High-Grade Silver Zones** 

**at the La Colorada Mine**

**Vancouver, B.C. – September 8, 2025 - Pan American Silver Corp.** (NYSE: PAAS) (TSX: PAAS) ("Pan American" or the "Company") announces new drill results for its La Colorada mine in Zacatecas, Mexico, including multiple high-grade veins that indicate the potential for expansion of silver mineral resources, extension of mine life and improved economics. These drill results build on the success of Pan American's exploration program targeting the eastern zone of the La Colorada mine.

"Our exploration efforts have identified high-grade intercepts below and along the strike of the known La Colorada vein system, east of the defined mineral resource footprint demonstrating opportunities for further mineral resource expansion," said Christopher Emerson, Pan American's Senior Vice President of Exploration and Geology. "The discovery of a new high-grade replacement style of mineralization, and vein style mineralization, particularly in the San Geronimo and Cristina zones in the southeastern portion of the property, will be reflected in an update to the estimated mineral resources for the La Colorada mine when the Company reports its annual mineral reserves and mineral resources as at June 30, 2025."

The drill results highlighted in this news release reflect the exploration program at La Colorada for the period November 2024 to June 2025 with approximately 65,000 metres drilled across 170 holes. All intercepts are reported as estimated true widths in metres ("m"), unless indicated otherwise. Please refer to the "La Colorada Drill Result Highlights" table on pages four to six of this news release for additional details. The full table of drill results, collars, plans and long sections for this period is available at https://panamericansilver.com/operations-2/silver-segment/la-colorada/ together with previously reported drill results for La Colorada.

**EXPLORATION HIGHLIGHTS**

**Eastern Extensions to Mariana and NC2 Veins**

Infill and exploration drilling at the La Colorada mine continue to delineate multiple high-grade silver and base metal intercepts, significantly extending mineralization eastward along the NC2 and parallel Mariana vein systems, as well as into secondary structures located east of the current underground production area.

The Mariana vein now spans an approximate strike length of 1,000 metres with a vertical extent exceeding 350 metres, while the NC2 vein system exceeds 2,000 metres on strike with a vertical extent of over 500 metres. Exploration development on four levels of the mine, between 1,900 to 2,100 metres above sea level, has advanced over 300 metres east.

Notably, recent drill results indicate higher gold grades, prompting further evaluation of the gold potential in future mine production. The mineralized structures remain open laterally and at depth, indicating significant opportunity for continued mineral resource expansion.

Drill hole result highlights over the report period from Mariana and NC2 vein systems include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• S-77-25 with 3.66m @ 3,844 g/t Ag, 2.30 g/t Au, 4.53% Pb, 11.05% Zn (Mariana vein)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• U-84-25 with 11.61m @ 811 g/t Ag, 0.86 g/t Au, 8.21% Pb, 22.31% Zn (Mariana vein)

**Discovery of a new style of mineralization**

Recent exploration drilling has identified a new style of high-grade silver and base metal replacement mineralization at the lithological contact between volcanic and sedimentary host rocks in the southeastern mine area. This discovery marks a new mineralization style for the La Colorada vein system. Several historic drill holes have been integrated into the following list of drill hole results to support geological reinterpretation, highlighting the significance of this new finding.

This contact-related mineralization style represents a high-potential exploration target south of the current mine, adjacent to the Cristina/San Geronimo corridor. It also offers the potential for expanding inferred mineral resources, which will be included in Pan American's annual mineral reserves and mineral resources as at June 30,

**Cautionary Note to US Investors**

This news release has been prepared in accordance with the requirements of Canadian NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards, which differ from the requirements of U.S. securities laws. 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 public disclosure standards, including NI 43-101, differ significantly from the requirements of the SEC, and information concerning mineralization, mineral reserve and mineral resource information contained or referred to herein may not be comparable to similar information disclosed by U.S. companies. The requirements of NI 43-101 for identification of "reserves" are not the same as those of the SEC and may not qualify as "reserves" under SEC standards. Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. U.S. investors should also 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. Under Canadian securities laws, estimated "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases.

**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: the extent of, and success related to any future exploration or development programs, including with respect to the exploration program at the La Colorada Skarn; expectations regarding exploration drilling; and plans to report our annual mineral reserve and mineral resource as at June 30, 2025.

These forward-looking statements and information reflect Pan American's current views with respect to future events and are necessarily based upon a number of assumptions that, while considered reasonable by Pan American, are inherently subject to significant operational, business, economic and regulatory uncertainties and contingencies. These assumptions include: tonnage of ore to be mined and processed; ore grades and recoveries; prices for silver, gold and base metals remaining as estimated; currency exchange rates remaining as estimated; capital, decommissioning and reclamation estimates; our mineral reserve and resource estimates and the assumptions upon which they are based; prices for energy inputs, labour, materials, supplies and services (including transportation); no labour-related disruptions at any of our operations; no unplanned delays or interruptions in scheduled production; all necessary permits, licenses and regulatory approvals for our operations are received in a timely manner; our ability to secure and maintain title and ownership to properties and the surface rights necessary for our operations, including contractual rights from third parties and adjacent property owners; and our ability to comply with environmental, health and safety laws. The foregoing list of assumptions is not exhaustive.

Pan American 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 Pan American 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, GTQ, CAD, CLP, and BRL 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); risks relating to the credit worthiness or financial condition of suppliers, refiners and other parties with whom Pan American does business; risks related to taxation; inadequate insurance, or inability to obtain insurance, to cover these risks and hazards; 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; changes in national and local government, legislation, taxation, controls or regulations and political, legal or economic developments in Canada, the United States, Mexico, Peru, Argentina, Bolivia, Guatemala, Chile, Brazil or other countries where Pan American may carry on business, including legal restrictions relating to mining, risks relating to expropriation, and risks relating to the constitutional court-mandated ILO 169 consultation process in Guatemala; 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 Pan American's most recent form 40-F and Annual Information Form filed with the United States Securities and Exchange Commission and Canadian provincial securities regulatory authorities, respectively. Although Pan American 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. Pan American 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.
