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
Article content
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.
