SUMMARY OF EXPLORATION RESULTS

Jacobina mine, Brazil

The Jacobina mine is an underground paleo placer gold mine located in the state of Bahia in northeastern Brazil. The mine has a strong track record of mineral reserve and mineral resource replacement and growth. The mine complex and resources extend over eight kilometres with exploration targets extending over a 14 kilometre trend of conglomerate reefs hosting gold mineralization, many of which remain open to depth and along strike.

Brownfield exploration drilling totaled 35,583m, primarily targeting the João Belo Sul, Morro do Vento, Maricota, Serra do Corrego, and João Belo Norte zones. Exploratory drilling focused on evaluating new near-mine targets down-dip and north of Maricota. The recent exploration results continue to highlight the significant potential for expanding mineral reserves and mineral resources at Jacobina.
Infill drilling at João Belo Sul confirmed gold mineralization continuity, particularly in higher-grade zones proximal to existing underground infrastructure at João Belo Norte mine. Notable intercepts include: 3.26m @ 8.21 g/t Au (JBS00093); 2.07m @ 5.55 g/t Au and 5.70m @ 4.63 g/t Au (JBS00094).

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 and La Colorada), mine laboratories operated by third party independent commercial labs (Huaron), and commercial laboratories off-site (La Colorada, El Peñon, Minera Florida, 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). 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 March 26, 2024, 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, 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, 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. 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 its Jacobina, El Peñon, La Colorada, Minera Florida, Huaron and Timmins properties and for its La Colorada Skarn and Whitney projects, and the potential impact of any such 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; 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.
