At Maqui Norte, infill and exploration drilling generated new inferred and indicated mineral resource, extending approximately 150 metres north of the reported mineral reserves and infrastructure. The structure remains open down-dip and along approximately 300 metres strike length to the north to the PBE vein intersection. Drilling highlights include: 1.66m @ 11.34 g/t Au, 48 g/t Ag, 2.06% Zn (ALH5065); and 1.06m @ 20.19 g/t Au, 11 g/t Ag, 0.28% Zn (ALH5025-Maqui C IV).
At Don Leopoldo Sur, infill and exploration drilling extended mineralization approximately 50 metres below current mine infrastructure. Highlights include: 1.84m @ 5.03 g/t Au, 11 g/t Ag, 3.11% Zn (ALH5059); and 1.98m @ 9.56 g/t Au, 18 g/t Ag, 8.37% Zn (ALH5035). Mineralization remains open at depth at Don Leopoldo Sur and W, with future drilling planned.
At Lo Balta, exploration and infill drilling extended inferred mineral resource and indicated mineral resource approximately 150 metres east along Lo Balta and Cipres structures, with an additional 150 metre strike potential open to the Centenario vein intersection. Key results include: exploration drill hole ALH4691 at Lo Balta, with 1.08m @ 8.78 g/t Au, 13 g/t Ag, 1.55% Zn; infill drill holes ALH4773, Lo Balta Norte vein, with 0.82m @ 15.15 g/t Au, 28 g/t Ag, 7.36% Zn; ALH4804, Cipres vein, with 0.91m @ 16.60 g/t Au, 73 g/t Ag, 2.39% Zn; and 3.28m @ 13.84 g/t Au, 11 g/t Ag, 1.42% Zn (Centenario 1 vein – ALH5009).
Cerro Moro, Argentina
Cerro Moro is an underground and open pit epithermal gold-silver mine located in the Patagonia region of southern Argentina.
For the period November 2024 to October 2025, exploration drilling totaled 34,764 metres, including 28,871 metres of infill drilling targeting conversion of inferred mineral resource, 4,544 metres of exploration drilling to delineate new inferred mineral resources, and 1,349 metres of exploratory drilling to identify new mineralization. Efforts focused primarily on defining and expanding the new Naty Condor discovery (approximately 11 kilometres south of the operation.). Additionally, drilling was carried out along the 3.5 kilometre-long Nini core mine structure, and on the newly defined Vein 4 structure at the Naty open pit, approximately 23 kilometres south-southwest of the operation.
Naty Condor, discovered in late 2023 with initial drilling in mid-2024, features mineralization along an approximately 700 metre long northwest-trending corridor, delineated to depths of 50 to 90 metres below surface within multiple coalescing structures that form wide, often high-grade zones. Mineralization is hosted by and proximal with the contact between bedded sedimentary strata and felsic volcaniclastic rocks. Mineralization remains partially open to depth and along strike to the northwest and southeast. Notable intercepts include: 17.95m @ 13.51 g/t Au, 228 g/t Ag, incl. 2.94m @ 55.14 g/t Au, 956 g/t Ag (MD4812); 10.35m @ 8.22 g/t Au, 265 g/t Ag (MD4951); 16.80m @ 9.24 g/t Au, 36 g/t Ag (MD5153); 0.59m @ 99.60 g/t Au, 3,167 g/t Ag and 9.25m @ 10.16 g/t Au, 101 g/t Ag (MD5147); 10.54m @ 14.00 g/t Au, 137 g/t Ag, incl. 0.90m @ 87.60 g/t Au, 280 g/t Ag (MD4881); 20.27m @ 4.20 g/t Au, 69 g/t Ag, incl. 1.45m @ 29.66 g/t Au, 71 g/t Ag (MD5046); and 17.85m @ 21.84 g/t Au, 975 g/t Ag, incl. 6.24m @ 34.16 g/t Au, 1,254 g/t Ag (MD5037).
At the Nini zone, shallow infill and exploration drilling returned positive results, which are expected to add new mineral resources to be reported as at June 30, 2026. Drilling highlights include: 1.37m @ 6.50 g/t Au, 777 g/t Ag (MD4936); 4.64m @ 9.51 g/t Au, 564 g/t Ag (MD4943); 1.28m @ 6.36 g/t Au, 1,167 g/t Ag (MD4976); and 1.84m @ 31.91 g/t Au, 1,095 g/t Ag (MD5129).

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 at www.sedarplus.com, or the Company’s most recent Form 40-F filed with the United States Securities and Exchange Commission (the "SEC") for further information on the Company’s material mineral properties, including detailed information concerning associated QA/QC and data verification matters, the key assumptions, parameters and methods used by the Company to estimate mineral reserves and mineral resources, and for a detailed description of known legal, political, environmental, and other risks that could materially affect the Company’s business and the potential development of the Company’s mineral reserves and mineral resources.
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.

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: plans to drill a total of approximately 540,000 metres in 2025; the extent of, and success related to any future exploration or development programs, including with respect to its Jacobina, El Peñon, La Colorada, Timmins, Huaron, Minera Florida, and Cerro Moro mines, and the potential impact of any drill results on the Company’s mineral reserves or mineral resources.
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; 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, 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; the duration and effects any pandemics on our operations and workforce; 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.
