(NYSE: PAAS) (TSX: PAAS) ("Pan American" or the "Company") released new drill results for its Jacobina, El Peñon, La Colorada, Huaron, Timmins, Minera Florida and Cerro Moro mines.Pan American Silver Corp.

“In 2025, we continued to advance our long-term exploration strategy aimed at replacing and growing our mineral resources, with strong results across several key operations,” said Christopher Emerson, SVP Exploration and Geology. “At Jacobina, drilling to the north of the Maricota deposit is confirming the potential to expand the resource beyond currently defined limits. At El Peñon, drilling is identifying new mineralized structures both within the main mine area and at nearby targets, including Fortuna and the newly discovered Dominadora vein. At La Colorada, recent drilling in the eastern and deeper parts of the mine continues to return compelling grades and widths, and we are also advancing a highly prospective replacement-style target along the contact between limestone and volcanic rocks.”

Pan American's exploration program focuses on near-mine exploration and resource conversion throughout its portfolio of operating mines. This release provides an exploration update on the 333,830 metres that have been drilled at the mines referenced in this news release, which represents 70% of the total metres drilled for the period November 1, 2024 to October 30, 2025. The Company plans to drill a total of approximately 540,000 metres in 2025.

EXPLORATION HIGHLIGHTS:

All intercepts are reported as estimated true widths in metres ("m"). Please refer to the Drill Result Highlights Tables beginning on page seven of this news release for additional details.

General Notes with Respect to Technical Information

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.

Samples are analyzed at a variety of laboratories, including by in-house staff at the mine (Jacobina, La Colorada and Cerro Moro), mine laboratories operated by third party independent commercial labs (Huaron), and commercial laboratories off-site (La Colorada, El Peñon, Minera Florida, Cerro Moro, Whitney and Jacobina). All the assay data reported in this news release 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 on a monthly and quarterly basis by management. In general, the assay analytical technique for silver, lead, zinc and copper is acid digestion with either ICP or atomic absorption finish. The analytical technique for gold uses fire assay and atomic absorption spectrometry (AAS) finish. A gravimetric finish would be used if the gold assay exceeds > 10 g/t (or >5 g/t at El Peñon). At Cerro Moro, the analytical technique for silver uses fire assay and AAS finish. If the silver assay exceeds 1,000 g/t, a gravimetric finish is used. The results of the QA/QC samples submitted for the resource databases demonstrate acceptable accuracy and precision. The offsite commercial laboratories are independent from Pan American and certified by ISO 17025:2017.

The Qualified Persons are of the opinion that the sample preparation, analytical, and security procedures followed for the samples are sufficient and reliable for the purpose of this news release and for the purpose of any future mineral resource and mineral reserve estimates. There were no limitations on the Qualified Persons' verification process. 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.

Mineral resources and mineral reserves are as defined by the Canadian Institute of Mining, Metallurgy and Petroleum.

See the Company’s Annual Information Form dated February 19, 2025, available atwww.sedarplus.com

Technical information contained in this news release with respect to Pan American has been reviewed and approved by Christopher Emerson, FAusIMM, Senior Vice President Exploration and Geology, and Martin Wafforn, P.Eng., Senior Vice President Technical Services and Process Optimization, each of whom is a Qualified Person for the purposes of National Instrument 43-101 - Standards of Disclosure for Mineral Projects (‘‘NI 43-101’’). Pan American 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 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 (“CIM 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, deposits, mineral reserve and mineral resource information contained or referred to herein may not be comparable to similar information disclosed by U.S. companies. Canadian standards, including NI 43-101, differ significantly from the requirements of the SEC, 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 new release uses the terms “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 indicated mineral resources or inferred mineral resources that the Company reports are or will be economically or legally mineable. 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.
