Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) ("Pan American" or the "Company") today released results for 15 new infill and exploration drill holes totaling 14,122 metres at the Company's 100% owned La Colorada Skarn project in Zacatecas, Mexico.

The most recent drill results include eight holes that were drilled to follow up on high-grade drill results reported in news releases dated July 21, 2022 and November 1, 2022. Hole D-96-10-22 returned two broad zones of mineralisation over 64 metres at 391 g/t Ag, 10.8% Pb and 8.5% Zn, including 23.25 metres at 914 g/t Ag, 25.19% Pb and 16.73% Zn, and a separate lower skarn zone over 135 metres at 37 g/t Ag, 1.13% Pb and 6.42% Zn.

"These new drill hole results both extend the 902 zone and confirm that there are multiple zones of higher grade within the limestone and skarn, which align with surrounding porphyry intrusives and epithermal veins," said Christopher Emerson, Pan American's Vice President Exploration and Geology. "We have now drilled over 20 holes into this area, which remains open to the west and northwest. The 2023 infill and exploration program of 28,000 metres from surface and underground drilling stations is currently underway.”

Drill highlights include:

• D-96-10-22: 64.30 m at 391 g/t Ag, 0.13% Cu, 10.83% Pb and 8.50% Zn, including 23.25 m at 914 g/t Ag, 0.19% Cu, 25.19% Pb and 16.73% Zn and 135.70 m at 37 g/t Ag, 0.14% Cu, 1.13% Pb and 6.42% Zn
• D-96-12-23: 109.55 m at 233 g/t Ag, 0.10% Cu, 6.62% Pb and 7.32% Zn, including 44.20 m at 487 g/t Ag, 0.15% Cu, 15.46% Pb and 10.12% Zn
• D-96-09-22: 72.60 m at 98 g/t Ag, 0.07% Cu, 0.85% Pb and 4.11% Zn and 26.95 m at 162 g/t Ag, 0.05% Cu, 3.51% Pb and 3.52% Zn and 21.20 m at 123 g/t Ag, 0.11% Cu, 3.53% Pb and 8.63% Zn
• D-96-11-22: 17.05 m at 165 g/t Ag, 0.12% Cu, 4.37% Pb and 9.33% Zn
• U-138-22: 71.35 m at 193 g/t Ag, 0.15% Cu, 10.82% Pb and 9.27% Zn, including 57.95 m at 231 g/t Ag, 0.17% Cu, 13.11% Pb and 11.01% Zn
• U-112-22: 53.15 m at 141 g/t Ag, 0.06% Cu, 5.84% Pb and 5.46% Zn, including 15.15 m at 243 g/t Ag, 0.08% Cu, 11.31% Pb and 8.28% Zn
• D-15-02-22: 16.85 m at 121 g/t Ag, 0.28% Cu, 4.60% Pb and 9.58% Zn
• D-93-06-23: 21.45 m at 304 g/t Ag, 0.17% Cu, 4.75% Pb and 2.55% Zn and 143.3 m at 27 g/t Ag, 0.10% Cu, 2.93% Pb and 4.68% Zn and 74.20 m at 49 g/t Ag, 0.25% Cu, 1.50% Pb and 4.36% Zn

Eight of the 15 drill holes reported in this news release are recent infill and extension holes that add definition to the high-grade areas, which are now drilled at roughly 30 metre spacing. Five infill drill holes: U-112-22, U-138-22, D-96-09-22, D-96-10-22 and D-93-06-23, confirm internal continuity of grade, similar to previously reported drill holes. The high-grade footprint has been extended approximately 50 metres to the northwest from the limit of prior drilling with recent holes D-96-11-22 and D-96-12-23 returning significant silver and base metal grades. This area remains open to the northwest where the ongoing drill program will continue to test further extension of the zone over the next few months from surface and underground drilling stations.

Exploration drilling in the 903 East mineralised zone was reduced in the fourth quarter of 2022 with a new focus on the high-grade area to the west. Recent results from S-101-22, the most southeast drill hole in the 903 zone, intercepts skarn mineralisation approximately 250 metres south of previous drilling. Drill hole D-09-04-22 intercepted mineralisation to the southeast of the central zone.
