McEwen Drilling Returns Significant Intersection at Gold Bar Mine Complex in Nevada: 5.55 gpt Gold over 44.2 Meters; Transformation into a Long-Life Mine Continues

TORONTO, Jan. 27, 2026 (GLOBE NEWSWIRE) -- McEwen Inc. (NYSE/TSX:MUX) ("McEwen" or the "Company") announces new drill results from the Gold Bar Mine Complex in the Eureka Mining District of Nevada, that continues to highlight the mine's transformation into a potential long-life operation. Results include the best hole drilled by McEwen to date at Windfall, which returned 5.55 gpt gold over 44.2 meters. Windfall, Lookout Mountain and Unity Ridge are three deposits at the Gold Bar Mine Complex that McEwen is advancing towards production. Gold Bar is an important part of the Company's plan to double production by 2030.

Best Hole Drilled by McEwen at Windfall – Now Targeting Deeper Extensions

Over the past six months, drilling at the northern end of the Windfall deposit has been returning good gold grades over long widths, with today's result from drill hole WF110 intersecting 5.55 gpt gold over 44.2 meters, including 48.38 gpt gold over 4.6 meters of oxide mineralization. This result followed up on other recently released holes along the same section that also intersected oxide mineralization, such as 2.43 gpt gold over 74.7 meters (drill hole WF039), 1.70 gpt gold over 64.0 meters (drill hole WF037) and 1.14 gpt gold over 67.1 meters (drill hole WF119). A deeper historical hole, located approximately 40 meters below these results, returned 3.75 gpt gold over 42.7 meters (drill hole EUR-P-237), indicating that the higher-grade mineralization remains open to expansion at depth (Fig. 2). Drilling is planned to target this deeper area in March. The Company believes there is good potential to continue expanding the mineralization with additional investment.

Definition Drilling Results Showing Excellent Continuity

As part of the Company's upcoming Mineral Resource Estimates, definition drilling has been continuing at Windfall. Recent results continue to indicate excellent continuity of near-surface oxide gold mineralization along segments of a 1.6-kilometer (1 mile) long north-south trending Windfall fault zone (Fig. 3). The gold mineralization at Windfall remains open to further expansion in multiple directions. Other new results are highlighted below.

Mineral Resource Estimate

The Company is currently completing a Mineral Resource Estimate for Lookout Mountain that will be published at the end of February. The updated Mineral Resource Estimate is expected to meaningfully increase the total ounces at the Gold Bar Mine Complex. The Company is planning to invest approximately $10 million into exploration in 2026 at Gold Bar. The results from the 2026 drilling program will be used to update the Mineral Resource Estimates, including initial Mineral Resource Estimates for Windfall and Unity Ridge, which are expected to have an additional positive impact.

2026 Development Path

In 2026, Windfall, Lookout Mountain and Unity Ridge will be subject to ongoing development work, such as metallurgical studies and mining designs, with the objective of advancing the deposits towards a production decision. Notably, Unity Ridge lies within the current Plan of Operations for mining activity at the Gold Bar Mine Complex and Windfall is located on private land, which should allow for an accelerated permitting process at both areas.

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

The Company's objective at the Gold Bar Mine Complex is to convert our exploration success into a long-life asset as we integrate Windfall, Lookout Mountain and Unity Ridge into our production plans. Since much of the gold mineralization in these areas is oxide, McEwen will look to utilize the existing Gold Bar infrastructure where possible. Our focus is on return on capital and how efficiently these new ounces can be developed and produced.
