Sentiment

Score: 9

Explanation: The filing reports significant high-grade gold discoveries at two key projects (Grey Fox and Windfall), with strong drill results and clear potential for resource expansion. Management's strategic goals for increased production and cost reduction, coupled with favorable gold prices, indicate a very positive outlook. The explicit comparisons to large, successful regional deposits further bolster confidence.

Positives

• Attractive gold grades and widths continue to be delivered at the Grey Fox Project, supporting near-term resource expansion.
• High-grade intercepts at Grey Fox include 10.1 g/t gold over 5.8 m and 10.4 g/t gold over 5.6 m in the Gibson Expansion Zone, and 4.8 g/t gold over 14.9 m in the GFS Zone.
• The updated 3D mineralization model for Grey Fox is expected to increase the forthcoming resource estimate.
• A new high-grade gold zone was discovered at the Windfall Project, with drill hole WF033 yielding 8.1 g/t gold over 8.7 meters, including 50.3 g/t gold, 782 g/t silver, 15% lead, 2.5% zinc over 1.3 meters (62.5 g/t gold equivalent).
• The Windfall discovery shows geological similarities to i-80 Gold's Ruby Hill Mine, a significant past producer.
• Permitting for the Windfall area could be faster than usual as it sits on private land.
• Oxidized gold mineralization at Windfall demonstrated strong cyanide recovery (above 60%), favorable for heap leach processing.
• The company is positioned to increase gold production and lower costs in 2026, with a goal to exceed 200,000 gold ounces annually.
• McEwen's gold-focused projects are well-positioned to capitalize on exceptionally performing gold prices.

Risks

• Actual results could differ materially from projections or estimates due to fluctuations in metal prices, economic and market conditions, and operating costs.
• Future drilling results may not meet expectations.
• The company's ability to receive or receive in a timely manner permits or other approvals required for operations could be impacted.
• Risks are associated with the construction of mining operations, commencement of production, and projected costs.
• Uncertainty exists as to the calculation of mineral resources and reserves.
• Foreign exchange volatility, controls, and currency risk could affect financial performance.
• The historical resource of 271,000 gold ounces at the Stroud property does not conform with current NI 43-101 requirements and requires verification.

Future Outlook

McEwen Inc. anticipates an updated Grey Fox resource estimate in October 2025 and a Pre-feasibility Study (PFS) in Q1 2026. For the Windfall Project, a resource estimate is targeted by year-end 2025, with plans to test mineralization extensions, conduct metallurgical testing, and explore new targets. The company aims to increase gold production and lower costs in 2026, with a long-term goal of growing annual output beyond 200,000 gold ounces and establishing a dividend.

Management Comments

• "We are delighted to have four key projects driving our gold mining business in both the near and long term."
• "Exploration drilling on our Fox Complex, specifically Grey Fox, continues to exceed expectations, while underground development at our Stock Mine and Froome West is progressing well."
• "We are also encouraged by the potential of our Nevada projects, where drilling will provide further exploration updates."
• "Our development work at the Stock Mine and Froome West positions us to increase gold production and lower costs in 2026, while Grey Fox remains our key project for long-term growth."
• "With gold performing exceptionally well, our gold-focused projects and operations put McEwen in a strong position to take advantage of higher prices."
• "Our goal over the next few years is clear: to grow annual output beyond 200,000 gold ounces and reduce production costs, generating stronger margins."

Industry Context

The reported high-grade gold discoveries and resource growth potential come at a time when gold prices are performing exceptionally well, positioning McEwen Inc. to capitalize on favorable market conditions. The geological similarities noted with major regional deposits like Canadian Malartic and i-80 Gold's Ruby Hill Mine suggest the potential for large-scale, long-life gold production, aligning with broader industry trends of seeking high-quality, expandable assets.

Comparison to Industry Standards

• The Grey Fox Project's geological characteristics and depositional environments are noted to be similar to the giant Canadian Malartic gold deposit near Val d'Or, Quebec, which has yielded large-scale, long-life gold production.
• The new high-grade zone at the Windfall Project shares similarities with mineralization at i-80 Gold's Ruby Hill Mine, which has produced 1.4 million ounces of gold, indicating comparable potential for significant gold mineralization.

Stakeholder Impact

• Shareholders are likely to benefit from potential resource growth, increased future production, and stronger margins, which could lead to higher share value and potentially a dividend.
• Employees and local communities at the Fox Complex and Nevada operations could see increased job security and economic activity due to expanded exploration and development activities.

Next Steps

• Publish an updated Grey Fox resource estimate in October 2025.
• Publish a Pre-feasibility Study (PFS) for Grey Fox in Q1 2026.
• Publish a resource estimate for the Windfall Project by year-end 2025.
• Test extensions of the mineralization at depth and along strike at Windfall.
• Collect samples for metallurgical testing at Windfall.
• Explore new targets near the Windfall project.
• Continue drilling at the Gibson Zone, including the Gibson Expansion Zone, with 50% of H2 2025 drilling focused there.
• Continue verification work, including relogging historical drill core and drilling confirmation holes, for the Stroud property's historical resource.

Key Dates

Recommendation

The filing presents highly positive exploration results, including new high-grade gold discoveries at both the Grey Fox and Windfall projects. These results significantly enhance the company's resource growth potential and future production outlook. Management's clear strategic objectives to increase gold output and reduce costs, combined with the current strong gold market, create a compelling investment case. The geological parallels to established, large-scale mines further de-risk the projects and suggest substantial long-term value creation. This combination of factors strongly indicates a 'strong buy' for a seasoned investor.
