Juanicipio Achieves Commercial Production

VANCOUVER, June 05, 2023 - MAG Silver Corp. (TSX / NYSE American: MAG) ("MAG" or "MAG Silver") is pleased to announce that commercial production has been achieved at the Juanicipio Project (56% / 44% Fresnillo plc ("Fresnillo") and MAG, respectively) effective June 1, 2023.

Following a successful commissioning period, the Juanicipio mine, processing facility and other vital systems are operating in line with, or rapidly approaching design capacity. The Juanicipio mill is operating at approximately 85% of its design capacity of 4,000 tonnes per day ("tpd") with silver recovery consistently above 88%. On a 100% basis, approximately 3.2 million ounces of silver have been produced from the Juanicipio processing facility from March 2023 to the end of May 2023, and production is expected to continue to increase steadily through Q3 where it is envisioned the plant will be running at design capacity. All major construction activities have now been completed and Juanicipio is demonstrating its ability to sustain ongoing production levels. The operations team is continually seeking opportunities to improve and optimize the mine, plant and other critical systems to achieve and potentially exceed design capacities.

"Reaching this important milestone of commercial production at Juanicipio completes our transformation from developer to producer," said George Paspalas, President and CEO of MAG Silver. "Today marks the beginning of a very exciting and dynamic growth phase for MAG as we combine stable, high-margin silver production with the ongoing high-grade exploration potential that has made and continues to make MAG so unique."
