McEwen Mining: Q3 Production

TORONTO, Oct. 30, 2023 (GLOBE NEWSWIRE) -- McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) is pleased to report production for Q3 2023 was 38,600 gold equivalent ounces (“GEOs”) and 104,800 GEOs for the nine months ended September 30^th, 2023. Our consolidated production guidance for 2023 is maintained, despite the Gold Bar Mine’s production forecast being 13% below its guidance range. Our forecast for the full year 2023 (see Table 1) reflects actual productions to September 30^th and management's current estimates for Q4 2023.

        Notes:
(1)   'Gold Equivalent Ounces' are calculated based on a gold-to-silver price ratio of 90:1 for Q3 2022, 82:1 for Q1 2023, 82:1 for Q2, 2023, and 81:1 for Q3 2023. 2023 production guidance is calculated based on an 85:1 gold-to-silver price ratio.
(2)   The San José Mine is 49% owned by McEwen Mining Inc. and 51% owned and operated by Hochschild Mining plc. Production is shown on a 49% basis.
(3)   El Gallo Mine (on care and maintenance) is expected to recover 2,300 gold oz in 2023 from plant and pond cleanout.

Gold Bar Mine, Nevada
Good progress has been made at Gold Bar recovering from a challenging first half of the year, as demonstrated by steadily increasing production quarter after quarter. Gold Bar has also maintained an excellent safety record with 1,313 days without a lost time injury as of September 30^th. Crushing and stacking of ore on the heap leach pad reached a rate of 9,300 tonnes per day (tpd) in September, a major improvement over the average in the prior eight months of 6,150 tpd. Year-to-date, ore containing 41,600 ounces of gold has been loaded onto the heap leach pad with an average expected recovery rate of 68%. Due to the gold inventory on the heap leach pad, we are confident in a reasonably strong Q4 continuing into the start of 2024. The 2023 production forecast is 13% below the guidance established in December 2022, due to a combination of factors including flooding and extreme weather in the Spring and a slower leach recovery rate of Gold Bar South ore.

Fox Complex, Timmins District
Fox performed well during Q3 and it is on track to slightly exceed the mid-point of our guidance range. Fox has achieved 738 days without a lost time injury as of September 30^th. Mining at Froome is on track and the Stock mill continues to increase average throughput. We are pleased with the good exploration drilling results seen at our Stock Complex including the ‘Ramp Portal Zone’, which may represent an early mining horizon for our upcoming Stock West project (see news release dated October 3^rd, 2023).

San José, Argentina
San José, which is operated by our joint venture partner Hochschild Mining, delivered Q3 production in line with our expectations for the quarter and guidance for the year. San José reported one lost time injury in August 2023, the worker has since recovered and returned to regular duty.

McEwen Copper
On October 11^th our McEwen Copper subsidiary announced additional investments by Stellantis and Nuton of ARS$42 billion and US$10 million, respectively. Since the creation of McEwen Copper, shareholders have invested $397 million (including investments by Stellantis in Argentine Pesos at official exchange rates at the time of each transaction) to acquire shares even though that the Company has remained private. The recent transactions occurred at $26.00 per share of McEwen Copper, giving it a market value of approximately $800 million. McEwen Mining retains 47.7% ownership of McEwen Copper, with an implied market value of $380 million, this represents a value accretion for McEwen Mining shareholders of $98 million or two (2) dollars per share since March 2023.

McEwen Copper is now well financed for the remainder of 2023 and well into 2024. The funds raised will be used to advance the feasibility study on the Los Azules project and for other corporate purposes. McEwen Mining also received proceeds of $6 million to augment its balance sheet.

Currently, we have fourteen drill rigs on site at Los Azules, scaling up to 18 drill rigs for our drilling campaign targeting more than 45,000 meters. This program will generate all the remaining data required to complete the planned feasibility study by Q1 2025.
