MUX McEwen Mining Inc

McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) is pleased to report full-year 2024 consolidated production of 135,900 gold equivalent ounces (“GEOs”)(1), within our guidance range for the year (press release dated Feb 12, 2024).

During 2024, Gold Bar and San Jose produced 44,600 and 60,100 GEOs, respectively, slightly exceeding the top end of our guidance ranges for those operations. At the Fox Complex, we produced 30,150 GEOs, which was below annual guidance due to a stope failure in early 2024 impacting production.

2025 Production and Cost Guidance

For 2025, we expect consolidated production to be between 120,000 and 140,000 GEOs attributable to MUX from all operations. The lower end of the 2025 range is driven by the planned transition of production at the Fox Complex from the Froome mine to the Stock mine in late 2025.

At Fox in 2025, due to permitting delays, the development of the ramp access to the Stock project is expected to continue through the majority of the year, with commercial production from Stock now expected in early 2026. Operations at the Froome mine will wind down in late 2025. The capital investment required for ramp development in 2025 has been partially funded by the US$22.0 million flow-through financing completed in June 2024.

At Gold Bar in 2025, the first half of the year is expected to deliver lower production relative to the second half, due to a scheduled continuation of high waste stripping in the Pick pit to be completed during 2025. The investment in waste stripping at the Pick pit is expected to improve ore availability during the second half of 2025 and through 2026, increasing future annual gold production.
