“The 902 zone at the La Colorada Skarn continues to return long intercepts in multiple drill holes, with the most recent drill holes returning some of the highest grade intercepts since we discovered the La Colorada Skarn in 2018. Hole U-121-22 contains the highest silver grade intercept in the Skarn, to date, of 22 metres averaging 1,435 g/t Ag, 31.9% Pb and 20.5% Zn within a broader interval of 78 metres of 568 g/t Ag, 12.5% Pb and 9.6% Zn,» said Christopher Emerson, Pan American’s Vice President of Exploration and Geology. «Exploration drilling continues to define the La Colorada Skarn mineral resource, and we look forward to presenting an updated mineral resource estimate in August 2024.”

Drill highlights include:

• U-121-22: 26.85 m at 127 g/t Ag, 7.19% Pb and 11.12% Zn and 77.85 m at 568 g/t Ag, 12.45% Pb and 9.59% Zn, including 22.50 m at 1,435 g/t Ag, 31.93% Pb and 20.49% Zn

• U-91-23: 372.10 m at 77 g/t Ag, 3.91% Pb and 5.79% Zn, including 83.85 m at 172 g/t Ag, 8.48% Pb and 10.49% Zn and including 26.90 m at 127 g/t Ag, 7.02% Pb and 11.69% Zn

• U-03-24: 68.00 m at 80 g/t Ag, 3.98% Pb and 6.98% Zn, including 29.00 m at 136 g/t Ag, 7.45% Pb and 12.82% Zn

General Notes with Respect to Technical Information

Grades are shown as contained metal before mill recoveries are applied. All samples provided in this news release were assayed by ALS Global, Mexico using acid digestion with ICP finish for silver, lead, zinc, and copper. For samples above the detection limits of ICP, they were finalized with absorption spectrometry («AAS»); For lead and zinc grades greater than 30%, the determination was made by volumetric titration. Samples sent to ALS Global were prepared in Zacatecas and Hermosillo, Mexico laboratories and sent to Vancouver, B.C. Laboratory for assay. Pan American implements a quality assurance and quality control («QAQC») program including the submission of certified standards, blanks, and duplicate samples to the laboratories. The results of the QAQC samples submitted to ALS Global demonstrate acceptable accuracy and precision. The Qualified Persons have verified the data disclosed in this news release and they are of the opinion that the sample preparation, analytical, and security procedures followed for the samples are sufficient and reliable for the purpose of any future 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. ALS Global is independent from Pan American.

See the Company’s Annual Information Form March 26, 2024, available at www.sedarplus.ca for further information concerning QAQC and data verification matters, 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.
