About

McEwen Inc. is a gold and silver mining production and exploration company with an advanced copper development project focused on the Americas. The company owns 100 percent of the Froome mine and Stock mill in Ontario Canada 100 percent of the Gold Bar Mine Complex in Nevada and 100 percent of the El Gallo project in Sinaloa Mexico. It holds a 46.3 percent interest in McEwen Copper Inc which owns the Los Azules copper project in San Juan Argentina and a 49 percent interest in MSC which owns and operates the San José mine in Santa Cruz Argentina. In addition McEwen Inc. holds interests in advanced stage and exploration stage projects in the United States Canada Mexico and Argentina.

Revenue is generated primarily from the sale of gold and silver produced at the company's operating mines. The Gold Bar Mine Complex and the Fox Complex produce doré bars that are sold to third party refiners under purchase agreements. The El Gallo project is advancing a heap leach material reprocessing initiative that will yield doré once operational. The San José mine produces both doré and concentrate which are sold to smelters and traders. In 2025 the Gold Bar Mine Complex contributed $116.7 million the Fox Complex contributed $76.0 million the El Gallo project contributed $4.8 million and the San José mine on a 49 percent basis contributed $225.2 million in revenue. Sales are made at prevailing spot market prices with some provisionally priced concentrates subject to final adjustments.

The company operates through the following segments: Canada United States Mexico MSC and McEwen Copper.

The Canada segment includes the Froome mine and Stock mill in Ontario Canada where gold and silver are produced from underground mining and milling activities and where the Stock Property is being developed as an underground mine with expected production start in mid 2026 and where exploration stage assets such as the Tartan Lake project are held.
The United States segment comprises the Gold Bar Mine Complex in Nevada which extracts gold and silver via heap leaching from the Pick Ridge and Gold Bar South deposits and also includes exploration stage properties such as the Tonkin Project the Timberline Resources holdings and the Lookout Mountain project.
The Mexico segment consists of the El Gallo project in Sinaloa Mexico where past mining and crushing ceased in the second quarter of 2018 and where the company plans to begin mill construction in the first half of 2026 for a heap leach material reprocessing project targeting an average annual output of about twenty thousand gold equivalent ounces once commercial production starts in mid 2027.
The MSC segment represents the company's 49 percent interest in MSC which owns and operates the San José mine in Santa Cruz Argentina where an underground mine produces gold and silver doré and concentrate through a crushing grinding flotation mill with some concentrate sent to third party smelters for toll processing.
The McEwen Copper segment reflects the 46.3 percent interest in McEwen Copper Inc which holds the Los Azules copper project in San Juan Argentina a copper development project with proven and probable copper reserves of 4.73 billion pounds and where the company is advancing studies toward eventual economic extraction.

McEwen Inc. positions itself as a mid tier precious metals producer with a diversified portfolio spanning gold silver and copper assets across the Americas. The company competes with larger established mining companies that possess greater financial resources and technical teams but it differentiates itself through a balanced mix of producing mines advanced development projects and exploration stage holdings. Its joint venture interests in the San José mine and the Los Azules project provide exposure to significant silver and copper resources while limiting sole capital commitments. The company's focus on the Americas and its ability to fund growth through equity markets and strategic partnerships support its competitive stance in the industry.

The company sells its doré and concentrate to a range of refiners smelters and traders. For the Gold Bar Mine Complex and the Fox Complex the primary customers are Asahi Refining and Auramet International LLC with approximately thirty two percent of sales going to Asahi and sixty six percent to Auramet in 2025. The San José mine sells its output to customers such as Aurubis LS Mining a Korean company and Trafigura which together accounted for fifty five percent of the mine's sales in 2025 with the remaining forty five percent spread among several other buyers. These arrangements allow the company to access spot market prices while maintaining reliable off take channels.

Investment Thesis

▲ Bull case

McEwen Mining (MUX) is strategically positioned to capitalize on the Los Azules copper project's financing progress, which represents a critical de-risking milestone for its long-term value creation. The recent agreement to secure a $2.4 billion loan package from an international financial institution, part of a broader $4 billion financing structure, demonstrates strong external validation of the project's economic viability and reduces execution uncertainty. Management's targeted 40-60 equity-to-debt split implies that MUX, through its parent company McEwen Mining, will need to contribute approximately $640 million in equity toward the $1.6 billion equity tranche, a figure that appears manageable given the company's market capitalization and potential access to capital markets. This financing framework not only advances the project toward its 2029-2030 production timeline but also enhances MUX's ability to attract strategic partners, as evidenced by ongoing discussions with Rio Tinto and other major industrial groups, which could lead to further non-dilutive funding or off-take agreements. The project's scale—positioned as one of the world's ten largest undeveloped copper deposits—and its goal to become Argentina's first copper cathode producer underscore its strategic importance in a global market facing structural copper supply deficits, thereby providing MUX with a high-conviction, long-term growth catalyst that is currently underappreciated by the market focused on near-term precious metal performance.
The advancement of Nuton LLC's copper leaching technology at Los Azules, which has already received a $100 million investment from Rio Tinto and is projected to extend the mine's life by 33 years according to a feasibility study, introduces a transformative operational advantage that significantly improves the project's long-term economics and sustainability profile. This technology enables lower-cost, environmentally favorable copper extraction compared to traditional smelting, aligning with increasing global demand for responsibly sourced metals and potentially qualifying the output for premium pricing or green financing incentives. By extending the operational lifespan beyond the initial reserve base, Nuton's innovation converts Los Azules from a finite-life project into a multi-decade asset, substantially increasing its net present value and reducing the perceived risk of premature obsolescence. This technological edge also strengthens MUX's negotiating position with potential partners and investors, as it differentiates the project in a competitive landscape where ESG compliance and operational efficiency are becoming decisive factors. The market is likely underestimating the compounding effect of this innovation on cash flow stability and terminal value, particularly as copper demand accelerates due to electrification trends, making Los Azules not just a mine but a durable, low-cost platform for value generation over the next half-century.
McEwen Mining's planned IPO of McEwen Copper targeting approximately $300 million in proceeds by the end of the year presents a near-term catalyst that could unlock significant shareholder value by providing monetary clarity and enabling strategic reinvestment. Meding's indication that October through December would be optimal timing, citing favorable copper prices and market outlook, reflects a sophisticated understanding of capital cycles and suggests management is aiming to maximize valuation amid strong commodity fundamentals. The IPO proceeds would not only fund MUX's equity contribution to Los Azules but could also strengthen the parent company's balance sheet, reduce reliance on dilutive financing, and provide flexibility for acquisitions or exploration upside in its existing precious metal portfolio. Furthermore, a successful IPO would establish a public valuation benchmark for the copper asset, potentially attracting broader institutional interest and improving liquidity for MUX shareholders who currently hold indirect exposure through a private subsidiary. By separating the high-growth copper project from the more volatile precious metal operations, the IPO could allow the market to re-rate MUX based on Sum-of-the-Parts valuation, revealing hidden value that is currently obscured by conglomerate discount effects and the long-dated nature of Los Azules' development timeline.

▼ Bear case

McEwen Mining (MUX) faces substantial execution and financing risks tied to the Los Azules project that the market may be underestimating, particularly given the project's reliance on external capital and unproven technology at extreme altitude. Despite progress on the $2.4 billion loan package, the full $4 billion financing structure remains incomplete, with the $1.6 billion equity tranche still subject to negotiation with Rio Tinto, McEwen Mining, and unspecified industrial groups—any delay or shortfall in securing this capital could push back the 2029-2030 production target and increase financing costs, especially if global interest rates remain elevated or copper prices weaken. The project's location at 3,500 meters above sea level introduces significant operational complexities, including logistical challenges, higher energy and water requirements, and potential workforce retention issues, all of which could escalate capital and operating expenditures beyond current estimates. Furthermore, while Nuton LLC's leaching technology promises life extension, its commercial scalability at Los Azules has not yet been demonstrated at full scale, and any technical underperformance could undermine the projected 33-year life extension and jeopardize the project's cost advantage, turning a supposed strength into a source of delay and cost overruns.
The dependence on Rio Tinto as both a minority stakeholder and potential strategic partner in Los Azules creates a material concentration risk for McEwen Mining, as Rio Tinto's 17.2% stake—backed by its $100 million investment in Nuton LLC—gives it considerable influence over key decisions, including technology deployment, financing terms, and potential future ownership changes. Although discussions with Rio Tinto are ongoing, there is no guarantee of a definitive partnership or additional investment, and the company's broader strategic priorities—such as its own copper projects and decarbonization goals—may not fully align with McEwen's timeline or financing needs. This dynamic could lead to stalemates in governance or conflicting objectives, particularly if Rio Tinto seeks to exert control or delay decisions to favor its internal projects. Moreover, McEwen Mining's ability to secure the remaining equity funding from "large North American, European, and Asian industrial groups" remains unverified, and any failure to attract these parties could leave MUX shouldering a disproportionate share of the equity burden, straining its financial resources and potentially forcing dilutive or disadvantageous financing terms.
The timeline for Los Azules—targeting production onset in 2029 or 2030—means that McEwen Mining shareholders will endure a prolonged period of negative cash flow and capital expenditure without meaningful near-term revenue contribution from the project, creating a significant opportunity cost and valuation drag. During this extended development phase, MUX will continue to rely on its precious metal operations, which are subject to volatile commodity prices, rising input costs, and geopolitical risks in jurisdictions like Mexico and the United States, potentially diverting management focus and financial resources away from core operations. The planned $300 million IPO of McEwen Copper, while viewed as a catalyst, carries its own risks: unfavorable market conditions in late 2024 could delay or weaken the offering, resulting in lower proceeds than anticipated and forcing MUX to bridge the funding gap through less favorable means. Additionally, even if successful, the IPO may not fully reflect the intrinsic value of Los Azules due to its long-dated nature and reliance on unproven technology, potentially leaving shareholders with a public entity that trades at a discount to private market valuations and fails to deliver the expected re-rating benefit, thereby exacerbating shareholder frustration over the lack of tangible returns amid years of investment in a distant future asset.
