Minaurum Drills High-Grade Silver on Europa Sur Vein Zone: 3.20 m of 882 g/t AgEq and 6.20 m of 374 g/t AgEq

Vancouver, British Columbia--(Newsfile Corp. - May 27, 2026) - Minaurum Silver Inc. (TSXV: MGG) (OTCQX: MMRGF) (FSE: 78M0) ( " Minaurum " or the " Company ") is pleased to report continued high-grade drill results from the Europa Sur, Travesia, and San Jose Vein Zones , as part of its ongoing Phase II, 50,000-metre resource expansion program at the Alamos Silver Project ("Alamos") in Sonora, Mexico. Highlights include: 3.20 m of 882 g/t silver equivalent ("AgEq") including 0.95 m of 2,423 g/t AgEq (Hole AL26-196) 6.20 m of 374 g/t AgEq including 1.85 m of 655 g/t AgEq (Hole AL26-196) 1.95 m of 255 g/t AgEq (Hole AL26-198) "The high-grade results from the southern extension of the Europa Sur vein zone reinforce the strong potential for resource growth in addition to the Quintera, Travesia, and San Jose vein zones at Alamos," stated Darrell Rader, President and CEO of Minaurum Silver. "Hole AL26-196 intersected significant gold and copper values alongside high-grade silver and base metals, suggesting the presence of a potential hot spot or feeder structure.

We look forward to releasing more results as assays are received." Figure 1. Plan view showing locations of Travesia, Quintera, Promontorio , and Europa vein zones . Click to enlarge.

Recent step-out drilling at Europa Sur has expanded the zone at depth and along strike returning high-grade silver, gold, copper, and base metal results (Table 1; Figures 2 and 3), bolstering earlier high-grade intercepts of 12.35 m of 408 g/t AgEq (Hole AL25-163), 1.10 m of 305 g/t Ag, 449 g/t AgEq (Hole AL26-185), and 0.60 m of 7
