MAG Announces Fourth Quarter and 2023 Production From Juanicipio

VANCOUVER, Jan. 24, 2024 - MAG Silver Corp. (TSX / NYSE American: MAG) ("MAG" or "MAG Silver") reports production from Juanicipio (56% / 44% Fresnillo plc ("Fresnillo") and MAG, respectively) for the fourth quarter ("Q4") and year ended December 31, 2023.

Q4 Highlights

• Solid processing performance: Juanicipio processed 346,766 tonnes of mineralized material in Q4, up from 322,249 tonnes in Q3 reflecting ongoing efforts to ramp up production and optimize operations.
• Robust production: Juanicipio produced 4.5 million silver ounces and 10,591 gold ounces in Q4.
• Strong grades: The average silver head grade for the quarter was 467 grams per tonne ("g/t"), marginally lower than the previous quarter but offset by higher gold and base metal grades. This continues to demonstrate the high-grade nature of the Juanicipio deposit.
• Optionality maintained: Juanicipio continued to capitalise on available milling capacity at the Saucito plant (100% Fresnillo owned) to maintain processing rates during periods of maintenance. Approximately 5% of the material processed during Q4 was processed through the Saucito plant.

2023 Full Year Highlights

• Processing growth: Juanicipio processed a total of 1,268,756 tonnes of mineralized material in 2023, exceeding expectations and achieving guidance of reaching nameplate during Q3 2023. Consistent processing growth quarter-on-quarter reflecting the commitment to scaling up operations.
• Record output: Juanicipio produced 16.8 million silver ounces and 36,732 gold ounces in 2023, a solid performance in its inaugural and ramp up year.
• Consistency: The average silver head grade for the year was 472 g/t, demonstrating the notable consistency of the Juanicipio deposit and solidifying its position as one of the highest grade silver mines in the world.
  

As reported to MAG by the project operator Fresnillo, mining rates continued to ramp up during the quarter supporting the increased processing rate of 346,766 tonnes of mineralized material across the Juanicipio and Saucito plants. The average silver head grade for the quarter was 467 g/t, marginally below the previous quarter as mining sequenced through lower grade. This was mitigated by higher throughput delivering preliminary production estimates for the quarter, before any adjustments from offtake agreements, of 4.5 million silver ounces and 10,591 gold ounces. Juanicipio produced 16.8 million silver ounces and 36,732 gold ounces for the year. MAG expects to release its comprehensive financial and operational results on March 19, 2023.
