Vancouver, British Columbia--(Newsfile Corp. - July 8, 2026) - Minaurum Silver Inc. (TSXV: MGG) (OTCQX: MMRGF) ("Minaurum" or the "Company") is pleased to report continued high-grade and wide-vein drill results from the Europa, Quintera, 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: (Drilled Thickness)
Quintera Vein Zone
5.95 m of 1,117 g/t silver equivalent ("AgEq")
(953 g/t Ag, 0.04 g/t Au, 1.21% Cu, 1.58% Pb, 0.41% Zn),
including 2.40 m of 2,557 g/t AgEq
(2,204 g/t Ag, 0.10 g/t Au, 2.83% Cu, 3.83% Pb, 0.98% Zn) (Hole AL26-215)
Europa Sur Vein Zone
3.65 m of 888 g/t AgEq
(713 g/t Ag, 0.33 g/t Au, 1.03% Cu, 1.52% Pb, 2.64% Zn)
including 2.65 m of 1,053 g/t AgEq
(841 g/t Ag, 0.44 g/t Au, 1.23% Cu, 1.98% Pb, 3.43% Zn) (Hole AL26-207)1.15 m of 459 g/t AgEq
(419 g/t Ag, 0.18% Cu, 0.08% Zn) (Hole AL26-207)0.30 m of 1699 g/t AgEq
(601 g/t Ag, 12.55% Cu) (Hole AL26-209)
"Historically, Quintera was the highest-grade and most productive vein at Alamos. Our drilling now demonstrates that this underexplored zone extends both to depth and along strike beyond the historical workings," stated Darrell Rader, President and CEO of Minaurum Silver. "These latest results include multiple robust high-grade silver intercepts that underscore Quintera's potential to become a major contributor to future resource growth at Alamos."
"At Europa, and particularly within the Europa Sur extension, drilling continues to return high-grade silver mineralization in hanging-wall veins as well as in the main Europa Sur vein. These results continue to validate our exploration model of multiple stacked, high-grade veins at Europa."

Quintera - Travesia Vein Zones
The historic Quintera mine produced an estimated 100 million ounces of silver with development reaching 16 levels to a depth of 500 m along a southwest-plunging shoot. Hole AL26-215 targeted the down-plunge projection of the Quintera vein zone, extending mineralization about 100 m below the significant high-grade results of 5.95 m of 1,117 g/t AgEq, below holes AL26-180 (5.30 m of 633 g/t AgEq: 570 g/t Ag, 0.01 g/t Au, 0.62% Cu, 0.16% Pb, 0.21% Zn) and AL26-188 (5.80 m of 658 g/t AgEq: 581 g/t Ag, 0.06 g/t Ag, 0.33% Cu, 0.87 g/t Pb, 1.08 g/t Zn) (see news release dated March 31, 2026). Assays are pending for hole AL26-206, which was drilled in the northern part of the Quintera vein zone.
