Heliostar Metals Drill Results Support Potential Mine Life Extension at San Agustin

• Heliostar Metals reported drilling results supporting a targeted two-year mine-life extension at its San Agustin gold mine in Durango, Mexico.
• The Corner Expansion and East Wall zones could provide 50% of the targeted extension, with grades and widths similar to current mining.
• The expanded drilling program targets 25,000-30,000 meters to follow up open mineralization and test additional targets toward completing the expansion objective in 2027.
• East Wall drilling returned 100.6 meters grading 0.42 grams per metric ton gold equivalent from surface.
• A mine-life extension decision depends on resource and reserve estimates, metallurgical and engineering work, and necessary permit modifications.
