Step-Out Drilling At McEwen’s Newly Acquired Tartan Mine Project

Returns Meaningful Results Along Western Flank

7.5 gpt Gold Over 18.9 Metres

Toronto, January 13, 2026 – McEwen Inc. (NYSE/TSX: MUX) (“McEwen” or the “Company”) is pleased to announce the final drill results to be included in the upcoming Mineral Resource Estimate for the Tartan Mine Project, near Flin Flon, Manitoba (Fig. 1). McEwen completed the acquisition of Tartan on January 5, 2026, through the purchase of Canadian Gold Corp. The updated Mineral Resource Estimate is expected to be released by the end of February and will be used to develop future plans as the Company targets doubling production by 2030. Highlights from the recent results include an intercept of 7.5 gpt gold over 18.9 metres. This expands the gold mineralization along the Western Flank beyond the previous result reported by Canadian Gold Corp., which returned 12.3 gpt gold over 14.0 metres (press release dated November 27, 2025). There appears to be excellent potential to further expand the size of the Tartan resource as the Main Zone is widening at depth while encountering similarly high gold grades (Fig. 3).

Western Flank at Tartan Mine Becoming Increasingly Important

The Western Flank at the Tartan Mine Project is located at the current western edge of the Main Zone (Fig. 2 & 3). It has been the primary focus of exploration during the past six months and has returned several notable drill intercepts, including today’s result of 7.5 gpt gold over 18.9 metres and intercepts released in late 2025, 12.3 gpt gold over 14.0 metres and 8.2 gpt gold over 9.9 metres (Fig. 3).

The objective of the ongoing drilling is to increase the number of ounces per vertical metre, which could allow for higher annual gold production in a potential mine restart while driving economies of scale to lower production and development costs. This objective is being achieved, driven by the success along the Western Flank that shows the strike length of the Main Zone having expanded from 100 metres near surface to approximately 150 metres at depth (Fig. 3). Two additional drill results along the Western Flank returned 6.6 gpt gold over 7.0 metres and 4.9 gpt gold over 7.9 metres. These results have expanded the gold mineralization approximately 30 metres further to the west, over a vertical distance of 80 metres (Fig. 3) (From 520 to 600 metres below surface).

Additional High Priority Exploration Targets at Tartan

The Company is currently budgeting $3 million for exploration at Tartan in 2026 and plans to increase this total if strong results continue to be delivered throughout Q1. In addition to expanding resources to the west, good opportunities remain in the following areas: 1) Eastern Flank of the Main Zone, 2) At depth within the Main Zone, 3) South Zone (parallel to the Main Zone), and 4) Regionally along the Tartan Lake Shear Zone (Fig. 1, 2 & 3). Since drilling was restarted by Canadian Gold in 2023, 35 of the 39 drill holes (approximately 90%) have successfully intersected what the Company believes to be potentially economic mineralization at the Main Zone.

Tartan Mine History

The Tartan Mine is located approximately 12 km northeast of Flin Flon, Manitoba within the Flin Flon Greenstone Belt (Fig. 1). Early exploration began in the 1920s, with construction of the Tartan Mine in the mid-1980s. Mining began in 1987 with a 250 tonne per day mill, which was further expanded to 500 tonnes per day. The mine produced approximately 47,000 ounces of gold before shutting down due to a decline in the gold price and mechanical challenges. The last NI 43-101 resource estimate was published in 2017 by Satori Resources Inc. (which became Canadian Gold Corp.) and showed Indicated resources of 240,000 ounces gold (1,180,000 tonnes at 6.32 gpt gold) and Inferred resources of 37,000 ounces gold (240,000 tonnes at 4.89 gpt gold) using a 3.0 gpt gold cut-off.

Why It Matters to Our Shareholders & the Value of Our Company

Tartan is an increasingly rare high-grade gold project in Canada that has had limited exploration between 1989 and 2023. We believe the recent results, combined with our planned investment into exploration, will allow Tartan to become one of the Company’s key growth drivers as we move towards our goal of doubling production by 2030. Tartan has the potential to become a lower cost, long-life mine. This year will be important as we publish the updated Mineral Resource Estimate and advance engineering and permitting to move towards a production decision. By leveraging existing mine infrastructure and the high-grade gold at Tartan, the Company aims to keep capital costs low and develop the mine in phases.

2025 Year-End Resource Estimate - Grey Fox Project

+23% Indicated to 1.9 Million Gold Ounces; Inferred 436,000 Gold Ounces

Upcoming Prefeasibility Study in Q2 2026

TORONTO, January 20, 2026 – McEwen Inc. (NYSE/TSX: MUX) (“McEwen” or the “Company”) is pleased to report its Year-End 2025 Mineral Resource Estimate for the Grey Fox Project, part of the Fox Complex in Timmins, Ontario. The 2025 Mineral Resource Estimate at Grey Fox now totals 1.9 million Indicated gold ounces and 436,000 Inferred gold ounces (calculated using a US$3,000 per ounce gold price), with good potential to increase the size of the resource through: 1) The recently acquired adjacent Stroud Property that contains a historical resource (Fig. 1), 2) New drill results received after the resource estimate cut-off date and 3) Optimization of the mine and plant design. Grey Fox will be an important part of the Company’s goal of doubling production by 2030, as we continue the Fox Complex’s transition into a long-life mining operation.

Grey Fox was previously envisioned as an underground project. The Company is now balancing both underground and open pit mining methods for calculating the Mineral Resource Estimate, consistent with the phased development mine plan that will be contained in the upcoming Pre-Feasibility Study (PFS). The PFS is scheduled to be published in Q2 2026. This project approach will allow the Company to maximize long-term project value, while providing early access to high-return gold ounces through existing ramp and underground infrastructure (Fig. 2).

Highlights of the 2025 Grey Fox Resource

Early Underground Mining at Grey Fox

The team at McEwen has identified two areas at Grey Fox where underground mining could be accelerated: 1) Gibson Zone, located near existing underground infrastructure, and 2) Whiskey Jack, which contains higher-grade gold areas (Fig. 1 & 2).

Gibson Zone is near existing underground infrastructure, including a ramp and portal from surface and contains Indicated Resources of 393,000 gold ounces (4.5 million tonnes @ 2.72 gpt gold) and Inferred Resources of 297,000 gold ounces (3.6 million tonnes @ 2.59 gpt gold).

Whiskey Jack, while smaller, is the highest-grade zone at Grey Fox and contains Indicated Resources of 122,000 gold ounces (735,000 tonnes @ 5.16 gpt gold) and Inferred Resources of 5,000 gold ounces (27,000 tonnes @ 5.84 gpt gold).

Both zones present opportunities for accelerated mining and high returns on capital. The Company will be detailing these opportunities in its pending PFS.

Open Pit Mining at Grey Fox

The PFS will also consider open pit mining. Ahead of the release of this study, McEwen is reviewing several scenarios to develop a plan that balances production with initial capital requirements, long-term value maximization, along with scheduling and permitting. The 2025 Mineral Resource Estimate and pending PFS will only consider the open pit mineralization that can be accessed by limiting the pit size to the area contained within the Company’s mineral claims (Fig. 1). Should the Company be able to reach an agreement with the adjacent owner and layback the open pit, there is an opportunity for additional resources to be included in future updates.

Stroud Project – Adjacent to Grey Fox Resource

The Stroud Project adjoins Grey Fox to the south and was acquired by McEwen in 2024 (Fig. 1). The project contains a historical, unpublished resource estimate of approximately 270,000 gold ounces. This resource does not conform to NI 43-101 guidelines and should not be considered current. In 2025, the Company successfully completed over 6,000 meters of drilling at Stroud to verify the historical resource. The Company anticipates publishing a Mineral Resource Estimate for Stroud with the next resource update for the Fox Complex.

Recent Drill Results Demonstrate Potential to Further Grow Resource

Additional drill results, such as 10.1 gpt gold over 5.8 meters from drillhole 25GF-1597, 5.2 gpt gold over 5.4 meters from drillhole 25GF-1599 and 23.8 gpt gold over 1.6 meters from drillhole 25GF-1605 (news release dated September 2nd, 2025), which were received after the cut-off for the 2025 Mineral Resource Estimate, highlight the potential to grow the resource with additional drilling. The Company is budgeting $5 to $10 million for drilling at Grey Fox in 2026.

Table 2. Grey Fox Resources: 2022 PEA, 2024 & 2025 Resource Comparison

Grey Fox is comprised of six gold zones (Gibson, Whiskey Jack, Contact, 147, 147 NE & Grey Fox South), ranging from approximately 25 meters to 800 meters below surface (see also the press release dated February 3rd, 2025). The decrease in resource grade reflects the lower cut-off due to higher gold prices and the incorporation of open pit mining. The slight decrease in Inferred resource ounces is the result of conversion to the Indicated category. Since the 2024 Mineral Resource Estimate(1) McEwen has completed over 64,000 meters of additional drilling.
