Exhibit 99.1

McEwen Receives $49.4 Million Dividend from San José Mine

Strong Cash Generation Supports Growth Without Meaningful Share Dilution

TORONTO, May 21, 2026 - McEwen Inc. (NYSE/TSX: MUX) (“McEwen” or the “Company”) today announced

that it has received a $49.4 million dividend from the San José Mine in Argentina. This brings total dividends

received from San José in 2026 to $58.2 million, already exceeding our original full-year expectation of $40–$50

million.

For shareholders, this matters for a simple reason: internally generated cash is the best source of capital. It allows a

company to grow while eliminating/minimizing share dilution, which is a key ingredient towards a higher share

price. At current gold and silver prices, and assuming operations perform as expected, we believe McEwen can fund

much of its planned production growth through cash generated by its own assets, as we look to double production to

250,000 – 300,000 GEOs by 2030.

McEwen’s attributable production from its 49% interest in San José is expected to be 59,000 – 64,000 GEOs in

2026, with AISC projected between $2,300 - $2,500 per GEO (based on a 77:1 silver/gold ratio).

Building our Financial Position

The $49.4 million dividend received further strengthens an already improving balance sheet.

At March 31, 2026, McEwen held:

· $56.5 million in cash and cash equivalents;

· $13.5 million in marketable securities;

· $15.7 million face value of McEwen Copper loan;

· $457 million and $20.4 million market value of investments in McEwen Copper and Paragon Advanced

Labs, respectively.

Our debt consists of $110 million long-term convertible notes maturing in 2030 and $20 million under our loan term

facility.

McEwen’s Near-Term Deliverables

Our objective is straightforward: increase production meaningfully over the next several years while improving the

quality and durability of our operations. McEwen is setting the stage to double production by 2030, with several key

deliverables expected in the coming months.

Stock Mine (Fox Complex, Timmins, Ontario)

Initial production at the Stock Mine is expected during the second half of 2026, with commercial production

anticipated in 2027.

McEwen Inc. Page 1

Stock should become a lower-cost source of production for the Fox Complex due to:

· Lower royalty obligations

· Shorter haul distances to the mill

· Softer material that is expected to reduce processing costs.

Current estimates indicate approximately six years of mine life, with additional exploration likely to extend that

horizon over time.

Grey Fox (Fox Complex, Timmins, Ontario)

The Grey Fox Pre-Feasibility Study is nearing completion and will be released in the coming months. Grey Fox is

important because it has the potential to significantly extend the productive life of the Fox Complex while utilizing

infrastructure we already own.

Using existing infrastructure to increase production generally produces better returns on capital than building entirely

new operations. By 2030, we are targeting 75,000 – 90,000 GEOs annually from the Fox Complex.

El Gallo (Sinaloa, Mexico)

Engineering work at El Gallo is progressing well, and mill construction is expected to begin in early Q3. Phase 1

production remains targeted for mid-2027 and is expected to produce approximately 20,000 GEOs annually for 10

years. What makes El Gallo particularly attractive is that existing infrastructure and land position may allow

additional production growth with comparatively modest capital requirements. Future phases could materially extend

mine life and increase annual production to approximately 40,000 – 50,000 GEOs.

ABOUT MCEWEN

McEwen shares trade on both the NYSE and TSX under the ticker MUX.

McEwen provides its shareholders with exposure to a growing base of gold and silver production in addition to a

very large copper development project with exciting optionality, all in the Americas. The gold and silver mines are

in prolific mineral-rich regions of the world: the Cortez Trend in Nevada, USA, the Timmins district of Ontario and

Flin Flon in Manitoba, Canada, and the Deseado Massif in Santa Cruz province, Argentina. McEwen is also

reactivating its gold and silver El Gallo Mine in Mexico.

The Company has a 46.3% interest in McEwen Copper, which owns the large, long-life, advanced-stage Los

Azules copper development project in San Juan province, Argentina – a region that hosts some of the country’s

largest copper deposits. According to the last financing for McEwen Copper, the implied value of McEwen’s

ownership interest is US$457 million.

The Los Azules copper project is designed to be one of the world’s first regenerative copper mines and

carbon neutral by 2038. Its Feasibility Study results were announced in the press release dated October 7, 2025.

McEwen also recently purchased 27.3% of Paragon Advanced Labs Inc. , a newly listed public company that is

deploying PhotonAssay™ units around the world, a technology that the Company believes is poised to become the

new industry standard for assaying precious and base metals, with Paragon aiming to be one of the leading service

providers.

Chairman and Chief Owner Rob McEwen has invested US$290 million personally and takes a salary of $1 per

year, aligning his interests with shareholders. He is a recipient of the Order of Canada, a member of the Canadian

Mining Hall of Fame and a winner of the EY Entrepreneur of the Year (Energy) award. His objective is to build

MUX’s profitability, share value, and ultimately implement a dividend policy, as he did while building Goldcorp Inc.
