MAG reported net income of $15,694 ($0.15 per share) driven by income from Juanicipio (equity accounted) of $21,069 and Adjusted EBITDA1 of $29,787 for the three months ended December 31, 2023.

A total of 346,766 tonnes of mineralized material at a silver head grade of 467 grams per tonne ('g/t') was processed at Juanicipio during the fourth quarter. Milling performance for 2023 totalled 1,268,757 tonnes at a head grade of 472 g/t.

Juanicipio achieved silver production of 4.5 million ounces during the fourth quarter. Silver production for 2023 totalled 16.8 million ounces.

Juanicipio continued to capitalize 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 the fourth quarter was processed through the Saucito plant.

Juanicipio delivered robust cost performance with cash cost2 of $3.76 per silver ounce sold and all-in sustaining cost2 of $9.17 per silver ounce sold in the fourth quarter.

Juanicipio generated strong operating cash flow of $84,038 and free cash flow2 of $61,993 in the fourth quarter. Operating cash flow and free cash flow2 for 2023 totalled $145,064 and $60,814, respectively.

CORPORATE

In September the Company published its second annual sustainability report underscoring its commitment to transparency with its stakeholders while providing a comprehensive overview of the Company's environmental, social and governance ('ESG') commitments, practices and performance for the 2022 year. The 2022 sustainability report is supported by the MAG Silver 2022 ESG Data Table which discloses MAG's historical ESG performance data.

During early 2024, as part of the Company's longer term succession planning, Dr. Lex Lambeck was promoted to the position of Vice President, Exploration. Lex has been the project manager for the Deer Trail Project in Utah since it was acquired by MAG in 2019, led by Dr. Peter Megaw. Lex's leadership was instrumental in the application of the 'Hub and Spoke' thesis at Deer Trail as well as the Carissa discovery demonstrating his strong skills in generative exploration in district scale settings which will be invaluable in overseeing the Company's portfolio of exploration properties, including exploration at Juanicipio.

Marc Turcotte, with his almost 10 years experience at MAG as Vice President, Corporate Development, was promoted to the position of Chief Development Officer. In this broader executive role, Marc will leverage his proven track record in identifying unique situations to zero-in-on and assess inorganic growth opportunities aligned with the Company's commitment to continued Tier-1 growth and expansion. Marc was the architect of the consolidation of the Deer Trail project in Utah as well as the catalyst behind the acquisition of Gatling Exploration which brought the Larder project into MAG's portfolio of high quality, high impact exploration properties.

Tom Peregoodoff was appointed to the Board of Directors of MAG effective January 1, 2024. Mr. Peregoodoff will fill the vacancy to be created by the planned retirement in June 2024 of Dan MacInnis, who does not plan to seek re-election at the Company's 2024 annual general meeting of shareholders. Tom brings with him over 30 years of industry knowledge and leadership and has extensive experience in all aspects and stages of the global mining business, specializing in mineral exploration.

EXPLORATION

Juanicipio: Infill drilling at Juanicipio continued in 2023, with one rig on surface and one underground with the goal of upgrading and expanding the Valdecanas Vein System at depth and further defining areas to be mined in the near to mid-term.

During 2023, 13,273 metres (three months ended December 31, 2023: nil metres) and 22,015 metres (three months ended December 31, 2023: 6,686 metres), were drilled from surface and underground respectively. Drilling for the year, both surface and underground, was infill in nature and continues to confirm defined mineralization.

Deer Trail Project, Utah: Results from the 12,157 metres in surface-based Phase 2 drilling on the Deer Trail Carbonate Replacement Deposit project were reported on January 17, 2023 and August 3, 2023.

On May 29, 2023 MAG started a Phase 3 drilling program focused on up to three porphyry 'hub' targets thought to be the source of the manto, skarn and epithermal mineralization and extensive alteration throughout the project area including that at the Deer Trail and Carissa zones. An early onset of winter snowfall impacted the commencement of the third porphyry 'hub' target which is expected to be drilled next season and drilling has shifted to offset the Carissa discovery and test other high-potential targets.

During 2023, 5,525 metres (three months ended December 31, 2023: 1,609 metres) were drilled at high elevation with final results and interpretation pending.

Larder Project, Ontario: On July 12, 2023 drilling resumed at the Larder Project to test additional targets by the end of the year on the Cheminis and Bear areas. During 2023 17,504 metres were drilled at Swansea, Cheminis and Bear.

Cheminis Success: The magnetotellurics survey carried out in the summer of 2023 enabled modelling of the south volcanic gold zone at Cheminis and is proving to be applicable elsewhere across the property. Drilling in three successive Cheminis drillholes intersected grades of 1.1 to 20.3 g/t gold over core lengths of 0.6 - 11.1 metres demonstrating continuity. This also extended the gold-hosting mine sequence down to 700 metres below surface, more than 370 metres below the deepest workings in this portion of the Cadillac-Larder Break. Incorporating these results into the model should enhance predictability in follow-up drilling.

Bear Success: Increased predictability has led to continued success and further definition of the North Bear zone, especially in hole GAT-23-022NA which cut 5.1 metres grading 4.6 g/t gold (including a high-grade zone of 1.4 metre grading 16.2 g/t gold). These intercepts extend gold mineralization to 650 metres below surface, and it remains open in all directions.
