Pan American Silver Announces 2023 Production and Cost Guidance

Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) ("Pan American") today provided its guidance for production, costs and certain expenditures in 2023. Pan American completed its previously announced transaction with Yamana Gold Inc. ("Yamana") on March 31, 2023, resulting in the addition of four producing mines (the "Acquired Operations"), plus several exploration and development projects in Chile, Brazil and Argentina. The guidance reflects the contribution from the Acquired Operations for the nine-month period from March 31 to December 31, 2023. Guidance for the original Pan American operations reflect the full 12-month period of 2023.

"The 2023 guidance is in line with our expectation for a material increase in silver and gold production together with lower consolidated operating costs following the acquisition of Yamana, indicative of the accretive nature of the transaction," said Michael Steinmann, President and Chief Executive Officer of Pan American. "The integration is progressing well and after only one month of ownership of the Acquired Operations, we are on track to realize the $40 to $60 million in annual synergies we had identified. Our teams are now focused on delivering the production and cost targets through the safe, efficient and environmentally sound operation of our mines."

Pan American reports mines under either a Silver Segment or a Gold Segment with costs calculated on a by-product basis (by-product metal sales a credit to costs to produce the primary metal for that segment). Yamana reported production and costs in gold equivalent ounces ("GEO"), which is not directly comparable to the way in which Pan American reports its production and costs.

The guidance also incorporates the application of Pan American's accounting and reporting policies to the Acquired Operations, of which the most significant changes relate to re-allocating large portions of previously capitalized mine development to operating expenses, and re-categorizing certain capital expenditures (including exploration and tailings facility expansions) from project capital to sustaining capital. This re-categorization will result in higher all-in sustaining costs ("AISC"). Specifically, for the Acquired Operations in 2023, Pan American is providing project capital guidance for Jacobina only, where it will be invested to complete certain growth-related projects that were already underway prior to the closing of the transaction with Yamana and to initiate a comprehensive mine optimization study. For the remaining Acquired Operations, all capital expenditures are being classified as sustaining capital for the remainder of 2023.

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.

2023 Production and Cost Forecast

2023 Consolidated Base Metal Production Forecast

2023 Capital Expenditure Forecast

In 2023, Pan American plans to invest an estimated $75 to $85 million of project capital in the following projects.

• At Jacobina, $26 to $29 million of project capital will be invested during the nine-months of 2023 to stabilize the operation with the expansion underway, which involves upgrading plant facility infrastructure to sustain a gold recovery of about 96%.
• At La Colorada, $16 to $18 million of project capital will be invested in: continued exploration and in-fill drilling on the Skarn project; advancing engineering work towards a preliminary economic assessment for the Skarn project, which is expected to be released in the second half of 2023; and advancing construction of the concrete-lined ventilation shaft, which is expected to benefit both the long-term development of the Skarn project, as well as the current vein-system operation. We expect to complete the concrete-lined ventilation shaft by the end of 2023 and install and commission the high-capacity fans in mid-2024. The shaft is currently at a depth of 270 metres, with the final depth being 560 metres. Pan American assumes mining ore below reserve grades until this additional infrastructure for the ventilation system is commissioned.
• At Huaron, $22 to $25 million of project capital will be invested in advancing the construction of a tailings pressure filtration plant and a dry-stack tailings storage facility to replace the conventional tailings storage facility currently in operation. The project is expected to be completed in 2024 and operational thereafter.
• At Timmins, $12 to $13 million of project capital will be invested in the construction of a paste fill plant at Bell Creek, which will improve backfill quality and availability for more effective ground support systems and to increase resource recovery and throughput.

General and Administrative and Greenfield Exploration Expenditures

In order to include ongoing adjustments, management intends to provide estimates for annual 2023 consolidated general and administrative expenses, greenfield exploration expenditures and care and maintenance spending as part of the unaudited financial results for the first quarter of 2023, scheduled to be released on May 10, 2023 after market close.

Strong Financial Position Post Completion of Yamana Acquisition

As at March 31, 2023, Pan American had cash and short-term investments of $513.1 million, inclusive of $204.7 million related to the MARA project in Argentina, and $425.0 million available under its $750.0 million revolving Sustainability-Linked Credit Facility.

In this news release, we refer to measures that are not generally accepted accounting principle ("non-GAAP") financial measures. These measures are widely used in the mining industry as a benchmark for performance, but do not have a standardized meaning as prescribed by IFRS as an indicator of performance, and may differ from methods used by other companies with similar descriptions. These non-GAAP financial measures include:

• Cash Costs. Pan American's method of calculating cash costs may differ from the methods used by other entities and, accordingly, Pan American's Cash Costs may not be comparable to similarly titled measures used by other entities. Investors are cautioned that Cash Costs should not be construed as an alternative to production costs, depreciation and amortization, and royalties determined in accordance with IFRS as an indicator of performance.
• All-in Sustaining Costs per silver or gold ounce sold, net of by-product credits ("AISC"). Pan American has adopted AISC as a measure of its consolidated operating performance and its ability to generate cash from all operations collectively, and Pan American believes it is a more comprehensive measure of the cost of operating our consolidated business than traditional cash costs per payable ounce, as it includes the cost of replacing ounces through exploration, the cost of ongoing capital investments (sustaining capital), general and administrative expenses, as well as other items that affect Pan American's consolidated earnings and cash flow.

This news release should be read in conjunction with Pan American's Audited Consolidated Financial Statements and Management's Discussion and Analysis for the year ended December 31, 2022, and Pan American's Annual Information Form for the year ended December 31, 2022.
