MCEWEN INC. JOINS RUSSELL 2000 INDEX

McEwen Inc. has been added to the Russell 2000 Index as part of the June, 2026, Russell reconstitution. The reconstitution becomes effective upon the opening of U.S. equity markets on June 29, 2026. Membership in the Russell 2000 Index is based on inclusion in the broad-market Russell 3000 Index.

The Russell 3000 Index represents approximately 98 per cent of the investable U.S. equity market by market capitalization and serves as the foundation for the Russell 1000 and Russell 2000 indexes. The Russell 1000 Index measures the performance of the largest 1,000 companies within the Russell 3000 Index while the Russell 2000 Index measures the performance of the smallest 2,000 companies within that universe.

Rob McEwen, chairman and chief owner of McEwen, commented: "We are delighted that McEwen has been added to the Russell 2000 Index. We believe this inclusion will increase McEwen's visibility among institutional investors and index-tracking strategies. As we continue advancing our portfolio of gold, silver and copper assets, we remain focused on executing our growth plans, strengthening operating performance and creating long-term value for our shareholders."

Russell indexes are global benchmarks widely used by investment managers and institutional investors for index funds and active investment strategies. According to data as of the end of June, 2025, about $12.2-trillion in assets are benchmarked against the Russell U.S. indexes, which belong to FTSE Russell, the global index provider.

Fiona Bassett, chief executive officer of FTSE Russell, an LSEG (London Stock Exchange Group) business, commented: "The Russell indexes have continuously adapted to the evolving dynamic U.S. economy, and it's crucial to fully recalibrate the suite of Russell U.S. indexes, ensuring the indexes maintain an accurate representation of the market. The transition to a semi-annual reconstitution frequency this year will ensure our indexes continue to represent the market and maintain the purpose of the index as a portfolio benchmark."

About McEwen Inc.

McEwen is a diversified gold, silver and copper company trading on the New York Stock Exchange and Toronto Stock Exchange under the ticker symbol MUX. The company provides shareholders exposure to a growing base of gold and silver production in prolific mineral-rich regions throughout the Americas, including the Cortez trend in Nevada, United States, the Timmins district of Ontario and Flin Flon in Manitoba, Canada, and the Deseado massif in Santa Cruz province, Argentina. McEwen is also advancing the reactivation of its El Gallo gold and silver mine in Mexico. The company's near-term objective is to double its total annual production to 250,000 to 300,000 gold equivalent ounces by 2030.

In addition, McEwen provides exposure to copper through its 46.3-per-cent interest in McEwen Copper, which owns the large, long-life, advanced-stage Los Azules development project in San Juan, Argentina. Based on the last equity financing for McEwen Copper, the implied value of McEwen's ownership interest is $457-million (U.S.).

Los Azules is being developed with the goal of becoming one of the world's first regenerative copper mines and achieving carbon neutrality by 2038. The feasibility study released on Oct. 7, 2025, highlights the project's strong economics and focus on environmental stewardship.

McEwen also recently purchased 27.3 per cent of Paragon Advanced Labs Inc., a publicly traded company 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 seeking to become a leading service provider in the sector.

Chairman and chief owner Rob McEwen has invested over $290-million (U.S.) personally and takes a salary of $1 per year, aligning his interests with those of the company's shareholders. He is a recipient of the Order of Canada, a member of the Canadian Mining Hall of Fame and winner of the EY Entrepreneur of the Year (Energy) award. His goal is to significantly multiply the value of McEwen shareholders' investments and his own, as he did while building Goldcorp Inc.
