MCEWEN MINING: 2023 PRODUCTION AND GUIDANCE FOR 2024

TORONTO, February 12, 2024 - McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) is pleased to report full year

and fourth quarter 2023 production results that represent a significant improvement year-over-year and

compared to prior quarters. Consolidated production in Q4 2023 was 49,850 gold equivalent ounces

(“GEOs”)(1), and full year production for 2023 was 154,600 GEOs. These results were consistent with our latest

forecast (Q3 results press release dated Nov 8, 2023) and within our guidance range for the year (press

release dated Mar 14, 2023).

Gold Bar production accelerated during Q4 and the month of December, making new records for the quarter

and the month, through the addition of mining crews and the completion of the heap leach pad expansion. At

Fox, production continued steady above 10,000 GEOs. San José production continued to strengthen

throughout the year, past the operational challenges of the first quarter.

In 2023, Gold Bar produced 43,700 gold ounces, within guidance range, Fox produced 44,450 gold ounces,

also within guidance range, and San José produced 65,650 GEOs, slightly below guidance range (see Table 1).

Our consolidated production is recovering after experiencing a challenging period from 2020. Looking ahead,

while we forecast lower production in 2024, the historic production trend remains positive.

2024 Production and Cost Guidance

For 2024, we expect to produce in the range of 130,000 to 145,000 GEOs attributable to MUX from all

operations (see Table 2). The reduction compared to 2023 is primarily driven by lower output from our Fox

operation and from San José, which is operated by our partner Hochschild Mining. We are currently

evaluating potential areas for enhancing production and profitability, and we will update our guidance

accordingly once any further improvements are implemented.

At Fox in 2024, we will be starting the development of underground ramp access to the Stock orebodies,

particularly Stock West, which will become the primary source of feed following the completion of mining the

Froome deposit in 2026. This capital investment is partially funded by the US$16.1 million flow-through

financing completed in December 2023.

At Gold Bar in 2024, the first half of the year is expected to deliver higher production relative to the second

half, due to a scheduled waste stripping phase in the Pick pit, in preparation for the 2025 mining program.

The mining sequence continues to be optimized.

Twenty drill rigs are currently on site at Los Azules and over 36,000 meters (118,000 ft) of drilling have been

completed so far this season, to advance all areas that contribute to the upcoming Feasibility Study (FS),

which is expected to be published in Q1 2025.

At the Los Azules Project, we've made significant progress. Our drilling program is over halfway complete,

with 36,000 meters drilled out of the 55,000 planned for our comprehensive feasibility study. The work

necessary for the completion of the feasibility study includes mineral resource estimation, metallurgical

testing, equipment selection, final completion and cost estimation of design for the mine and our facilities.

Additionally, we will work to advance our power and road infrastructure plans and establish preliminary

site-wide water balance including pit dewatering.

On the ground, we've made tangible progress with the drilling program, construction of our winter camp and

improvements to the exploration road facilitating year-round operations. We're also on track with

environmental permitting, reflecting our commitment to responsible development.

Financially, we've been diligent in protecting our treasury. The majority of our funds have been invested in

depository receipts of foreign and major Argentinean corporations, to shield us from devaluation. This

strategic move ensures that the Los Azules project's financial backbone stays robust in supporting our project

development.

“We are adapting to a changing environment in Argentina, recognizing the importance of current

political and economic reforms for the future stability and growth of the nation. Mining is a vital

component of Argentina’s economy and, under the right conditions, one that is poised to grow

significantly and support the country’s economic recovery,” said Michael Meding, VP of McEwen

Copper and General Manager of the Los Azules Project.
