MCEWEN RECEIVES $49.4 MILLION DIVIDEND FROM SAN JOSÉ MINE — STRONG CASH GENERATION SUPPORTS GROWTH WITHOUT MEANINGFUL SHARE DILUTION

McEwen Inc. has received a $49.4-million dividend from the San Jose mine in Argentina. This brings total dividends received from San Jose in 2026 to $58.2-million, already exceeding the company's original full-year expectation of $40-million to $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 toward a higher share price. At current gold and silver prices, and assuming operations perform as expected, the company believes McEwen can finance much of its planned production growth through cash generated by its own assets, as it looks to double production to 250,000 to 300,000 GEOs (gold equivalent ounces) by 2030.

McEwen's attributable production from its 49-per-cent interest in San Jose is expected to be 59,000 to 64,000 GEOs in 2026, with AISC (all-in sustaining costs) projected between $2,300 to $2,500 per GEO (based on a 77:1 silver/gold ratio).

Building the company's 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.

The company's debt consists of $110-million long-term convertible notes maturing in 2030 and $20-million under the company's loan term facility.

McEwen's near-term deliverables

The company's objective is straightforward: increase production meaningfully over the next several years while improving the quality and durability of its 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, Ont.)

Initial production at the Stock mine is expected during the second half of 2026, with commercial production anticipated in 2027.

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, Ont.)

The Grey Fox prefeasibility 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 the company already owns.

Using existing infrastructure to increase production generally produces better returns on capital than building entirely new operations. By 2030, the company is targeting 75,000 to 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 to 50,000 GEOs.

About McEwen Inc.

McEwen shares trade on both the New York Stock Exchange and Toronto Stock Exchange 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, U.S., 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-per-cent 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 $457-million (U.S.).

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 Oct. 7, 2025.

McEwen also recently purchased 27.3 per cent 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 $290-million (U.S.) 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.
