McEwen Inc.

The Tartan Mine Project is located in Flin Flon, Manitoba and was acquired as part of our Canadian Gold acquisition completed on January 5, 2026.

During Q2/26, a total of $2.3 million (H1/26 - $3.3 million) was incurred at the Tartan Mine Project to advance drilling, permitting, and metallurgical testing to optimize both process plant designs and underground mine plans, and engineering studies. The same factors which contributed to the H1/26 expenditures are expected to continue for H2/26. Further, a technical report was published in Q2/26 highlighting an estimated 308,900 ounces of indicated gold resources and 302,700 ounces of inferred gold resources.

As per the report, a second diamond drill was added to support exploration and infill drilling aimed at expanding the resource and upgrading inferred resources to indicated, for mine planning purposes. Results included significant assays from the deepest holes drilled to date in the South Zone, demonstrating mineralization at depth. Infill drilling along the eastern and western flanks of the main high-grade shoot also increased resource confidence and highlighted further growth potential.
