VANCOUVER, Dec. 28, 2022 - Pan American Silver Corp. (NASDAQ: PAAS) (TSX: PAAS) ("Pan American") today announces it has filed the management information circular (the "Circular") in respect of the special meeting (the "Meeting") of shareholders of Pan American ("Shareholders") to be held in connection with Pan American's proposed acquisition of all of the issued and outstanding common shares of Yamana Gold Inc. ("Yamana") and the sale by Yamana of its Canadian assets, including certain subsidiaries and partnerships which hold Yamana's interests in the Canadian Malartic mine, to Agnico Eagle Mines Limited ("Agnico"), by way of a plan of arrangement (the "Arrangement") under the Canada Business Corporations Act.

An electronic copy of the Circular is available on Pan American's website at https://www.panamericansilver.com/invest/arrangement-agreement-with-yamana/ and on SEDAR and EDGAR under Pan American's issuer profile at www.sedar.com and www.sec.gov, respectively.

Your vote is important regardless of the number of shares you own. Pan American encourages Shareholders to read the Circular in detail.

After careful consideration of the Arrangement, the Pan American Board of Directors UNANIMOUSLY RECOMMENDS
that Shareholders VOTE FOR the proposed resolution.

This is a transformational and strategic transaction for Pan American, which will strengthen Pan American's position as the leader in silver and gold production in Latin America.

Benefits to Shareholders include:

• A transformative increase in Pan American's scale, adding four producing mines, plus additional development projects in Latin America;
  
  
• Significantly improved trading liquidity (+50%)^[1] with a pro forma US$5.6 billion market capitalization^[2];
  
  
• Meaningful impact to production and margin, demonstrated by representative 2022 pro forma figures^[3]:
  
  
• Increase in annual silver production of approximately 9.5Moz;
  
  
• Increase in annual gold production of approximately 550koz;
  
  
• Expected lower overall cost structure - Yamana's Latin American assets forecast all-in sustaining cost ("AISC") of approximately US$981 per gold equivalent ounce ("GEO") in 2022;
  
  
• Broadens and diversifies Pan American's Latin American exposure with operations in two additional jurisdictions (Brazil and Chile);
  
  
• Pan American's scale, experience and expertise in Latin America maximizes its ability to integrate and optimize Yamana's Latin American assets;
  
  
• Significant potential synergies targeted to be US$40 million to US$60 million per year through the operational efficiencies from the combined Latin American portfolios and corporate general and administrative cost savings^[4];
  
  
• Accretive on a per share basis with respect to key financial and operating metrics, even before considering synergies;
  
  
• Robust pro forma revenue, which is expected to result in increased cash flow from operations allowing for improved capital allocation flexibility. For example, revenue on a pro forma basis would have been US$2.8 billion and US$2.0 billion for 2021 and the nine months ended September 30, 2022, respectively^[5];
  
  
• Improved ability to internally fund the La Colorada Skarn development and other growth projects;
  
  
• Adds assets with a long history of reserve replacement and an extensive exploration portfolio; and
  
  
• Enhances ability to return capital to shareholders.

The Meeting is scheduled for 10:00 a.m. (Vancouver time) on Tuesday, January 31, 2023, at Oceanview Suite, Pan Pacific Vancouver, 300 - 999 Canada Place, Vancouver, British Columbia, V6C 3B5, to consider an ordinary resolution to authorize the issuance of up to 156,923,287 Pan American Shares to the shareholders of Yamana as consideration in respect of the Arrangement.

Non-GAAP and IFRS Measures

This news release refers to various non-GAAP and IFRS measures, such as the AISC per GEO for Yamana's Latin American assets, which Yamana uses to manage and evaluate operating performance at each of its mines and are widely reported in the gold mining industry as benchmarks for performance, but do not have standardized meaning and are not a recognized measure under GAAP or IFRS. In particular, Yamana's and Pan American's calculations of AISC differ. To facilitate a better understanding of non-GAAP and IFRS measures as calculated by Pan American, please see "Alternative Performance (Non-GAAP) Measures" in Pan American's management discussion and analysis ("MD&A") for the year ended December 31, 2021, and in our MD&A for the three and nine months ended September 30, 2022. To facilitate a better understanding of these measures as calculated by Yamana, please see "Non-GAAP Financial Performance Measures" in Yamana's annual information form dated March 28, 2022, Yamana's MD&A for the year ended December 31, 2021, and Yamana's MD&A for the three and nine months ended September 30, 2022.
