Pan American Silver Announces Preliminary 2023 Production Results and Guidance for 2024

Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) ("Pan American") announces its preliminary production results for 2023 and its guidance for 2024. The 2023 production results reflect the addition of four producing mines following Pan American's acquisition of Yamana Gold Inc. ("Yamana"), which was completed on March 31, 2023; accordingly, annual consolidated production results and individual production results from Jacobina, El Peñon, Minera Florida and Cerro Moro (the "Acquired Operations") reflect production from the Acquired Operations during the nine-month period from March 31, 2023 to December 31, 2023, unless otherwise expressly stated. Production for the original Pan American operations reflects the full 12-month period of 2023.

• Consolidated silver production of 20.4 million ounces in 2023 was slightly below the 2023 guidance range of 21.0 to 23.0 million ounces provided in Pan American's news release dated April 27, 2023 (the "2023 Guidance"). Silver production increased by 11% compared with 2022.
• Consolidated gold production of 882.9 thousand ounces in 2023 was within the 2023 Guidance range of 870.0 to 970.0 thousand ounces. Gold production increased by 60% compared with 2022. Jacobina produced a record 196.1 thousand ounces of gold in 2023, including the first three months of 2023 prior to Pan American's acquisition of the mine (147.8 thousand ounces under Pan American's ownership).
• Consolidated zinc production of approximately 38.8 thousand tonnes in 2023 was below the 2023 Guidance of 41.0 to 45.0 thousand tonnes, lead production of approximately 18.7 thousand tonnes was within the 2023 Guidance of 18.0 to 21.0 thousand tonnes, and copper production of approximately 5.0 thousand tonnes met the 2023 Guidance of 5.0 thousand tonnes.

"Our 2023 production results reflect the significant contribution from the assets we acquired through the Yamana transaction, and are broadly in line with our expectations," said Michael Steinmann, President and Chief Executive Officer. "We expect 2024 to deliver a further increase in silver and gold production relative to 2023, with a full year contribution from the Acquired Operations combined with higher production at La Colorada following the completion of the new ventilation infrastructure mid-year. Our priorities for 2024 are the continued focus on the safe, cost-efficient operation of our mines, the completion of a study to define an optimized production rate for Jacobina, and the advancement of our La Colorada Skarn project."

2024 GUIDANCE

The following provides Pan American's operating outlook for 2024. Pan American reports mines under either a Silver Segment or a Gold Segment with costs calculated on a by-product basis; specifically, by-product metal sales are credited against the operating costs to produce the primary metal for that segment.

The following estimates contain forward-looking information about expected future events and financial and operating performance of Pan American. Readers should refer to the risks and assumptions set out in the "Cautionary Note Regarding Forward-Looking Statements and Information" at the end of this news release. Pan American may revise forecasts during the year to reflect actual results to date and those anticipated for the remainder of the year.

2024 Production and Cost Forecast

General 2024 Forecast Assumptions:

• Cash Costs and AISC forecasts assume metal prices of: $23.50/oz for silver, $1,950/oz for gold, $2,500/tonne ($1.13/lb) for zinc, $2,150/tonne ($0.98/lb) for lead, and $8,300/tonne ($3.76/lb) for copper.
• Average annual exchange rates relative to 1 USD of: 17.50 for the Mexican peso ("MXN"), 3.75 for the Peruvian sol ("PEN"), 980.00 for the Argentine peso ("ARS"), 7.00 for the Bolivian boliviano ("BOB"), $1.36 for the Canadian dollar ("CAD"), $850.00 for the Chilean peso ("CLP") and $5.00 for the Brazilian real ("BRL").
• A nominal average consolidated cost escalation rate of roughly 3% to 7%, depending on jurisdiction, including impacts of strong exchange rates in Brazil and Mexico. In general, higher cost escalations are attributed to wages and less to energy and consumables costs.
• Depreciation and amortization expenses of approximately $525 million in 2024, reflecting the expanded base of operations following the acquisition of Yamana.

Mine Specific 2024 Forecast Assumptions:

• La Colorada - an approximately 30% improvement in silver production at silver grades averaging 310 grams per tonne, contributing to an approximate 20% reduction in AISC relative to 2023 following completion of the new ventilation system, which is expected to be in mid-2024. Accordingly, the increase in production and lower costs are expected to be realized in the second half of 2024.
• Cerro Moro - silver production reflects mining lower grades than in 2023 due to mine sequencing while gold production expected to be similar to 2023.
• Jacobina - processing rates of approximately 8,400 tonnes per day at gold recovery rates of approximately 96%. AISC reflects the reallocation of $10 million of development costs to production costs.
• El Peñon - steady state production with throughput and grades similar to 2023.
• Timmins - production is back-end loaded due to mine sequencing.
• Shahuindo - production guidance reflects mine sequencing and ore blending considerations.
• La Arena - an increase in costs relative to 2023 reflects a higher waste-to-ore mining ratio of 2.30 due to mine sequencing.
• Dolores - mining and stacking on the heap are expected to conclude in the third quarter of 2024, with the property entering into its reclamation phase while residual leaching continues for a few years thereafter. The 2024 cost estimates for Dolores also include significant non-cash inventory draw downs, particularly during residual leaching.
• Huaron, San Vicente and Minera Florida - steady-state operations.

2024 Base Metal Production Forecast

2024 Expenditures Forecast

Planned Expenditures in 2024 Reflect the Following:

• La Colorada - $25.0 to $26.0 million of project capital will be invested in: continued exploration and in-fill drilling for the La Colorada Skarn project; advancing engineering work for the Skarn project, particularly in de-watering and geotechnical studies; and installing two high-capacity fans in mid-2024 as part of the new ventilation infrastructure.
• Huaron - $30.0 to $31.0 million of project capital will be invested to complete the construction of a tailings filtration plant and a dry-stack tailings storage facility that will replace the conventional tailings storage facility currently in operation. The project is expected to be completed in 2024 and operational thereafter.
• Jacobina - $14.0 to $15.5 million of project capital will be invested, primarily to complete projects to upgrade the processing plant, including the grinding circuit de-grit screening, completion of the process plant carbon-in-pulp circuit and tailings pipeline system upgrades to maintain stable processing rates of approximately 8,400 tonnes per day at gold recovery rates approaching 96%. Pan American is also developing a study throughout 2024 to potentially optimize the mining methods, production rates, future exploration strategies and long-term economics at Jacobina.
• Timmins - $11.0 to $12.5 million of project capital will be invested in the construction of a stage six tailings storage facility, and to complete the construction of a paste fill plant at Bell Creek. The paste fill plant is expected to be completed in the third quarter of 2024 and will improve backfill quality and availability, which is intended to increase resource recovery and throughput.
• Reclamation expenditures included in "Other" are mostly related to Manantial Espejo and progressive reclamation at Minera Florida and La Arena.
• Care and maintenance costs primarily reflect expenditures at Escobal, Manantial Espejo and Navidad. On January 14, 2024, President Bernardo Arévalo's new government took office in Guatemala. Pan American looks forward to continuing our participation in the government-led ILO 169 consultation process for the Escobal mine under the new administration. As usual, Pan American has not projected timing for a potential restart of the Escobal mine and has assumed a full year of care and maintenance costs at Escobal. The 2024 care and maintenance costs also reflect the substantial savings from the divestiture of the MARA project and the Morococha mine in 2023.
• General and administrative ("G&A") expenses are inclusive of realized and expected synergies at the head office of between $40.0 to $60.0 million, following the acquisition of Yamana.
• Regional greenfield exploration expenditures of $10.0 to $12.0 million are primarily directed at drilling in Brazil, Mexico and Canada. The expenditures relating to near-mine exploration targeting reserve replacement are included in the sustaining and project capital estimates provided above.
• Taxes paid of $95.0 to $100.0 million are front-end loaded with approximately half expected to be paid in the first quarter of 2024.
