Pan American Silver Reports Additional High-Grade Drill Results From the La Colorada Skarn Project

VANCOUVER, British Columbia–(BUSINESS WIRE)–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.

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 the Skarn exploration program at La Colorada; and expectations regarding testing from surface and underground drilling stations.

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: the world-wide economic and social impact of COVID-19 and the extent of any impacts related to the COVID-19 pandemic; 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: the duration and effects of COVID-19, and any other pandemics on our operations and workforce, and the effects on global economies and society; 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 in Canada, the United States, Mexico, Peru, Argentina, Bolivia, Guatemala, Chile, Brazil or other countries where Pan American may carry on business, including legal restrictions relating to mining, including in Chubut, Argentina, 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; 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.
