Vancouver, British Columbia--(Newsfile Corp. - February 26, 2026) - Minaurum Silver Inc. (TSXV: MGG) (OTCQX: MMRGF) (FSE: 78M0) ("Minaurum" or the "Company") is pleased to report that six drill rigs are now operating at its Alamos Silver Project as part of the Phase II - 50,000-metre resource expansion drill program. Minaurum will continue step-out drilling on vein zones with established resources at Europa and Promontorio-Travesia, while initiating resource-definition drilling on several additional veins, including San Jose, Quintera, Cotera-Pulpito, and Minas Nuevas.

Recent step-out drilling at Europa has returned multiple high-grade silver intercepts, including: 0.50 m of 524 g/t silver equivalent ("AgEq") in hole AL25-172, 0.30 m of 1,032 g/t AgEq in hole AL25-174 and 1.40 m of 290 g/t AgEq in hole AL25-175. At Travesía-Quintera, step-out drilling returned 2.55 m of 197 g/t AgEq, including 0.40 m grading 567 g/t AgEq in hole AL25-173 (see Table 1).

"With the continued success of our step-out drilling at the Europa vein zone, we are pleased to have expanded our drill fleet from four to six rigs," stated Darrell Rader, President and CEO of Minaurum Silver. "Supported by an inferred resource of 55 million ounces AgEq at Alamos and a fully funded 50,000-metre resource expansion program currently underway, Minaurum is well positioned to deliver an updated mineral resource estimate in the second half of 2026. We anticipate a steady increase in drill results as the expanded fleet advances the program."

Mineralization at the Europa and Travesia-Quintera zones has intersected high-grade silver over narrower widths that clearly define the margins of the robust silver shoots. The vein system displays a well-developed pinch-and-swell geometry along strike and down-dip, characterized by variations in vein thickness and grade. This continuity is exemplified by Hole AL25-163 at Europa, which returned 12.35 metres grading 408 g/t AgEq, including 3.20 metres of 1,277 g/t AgEq, in a 250-metre step-out (see Minaurum news release dated February 10, 2026), demonstrating a potentially large expansion of the mineralized envelope.

At Quintera, drilling continues to intersect mineralization within and surrounding historic underground workings, as well as in parallel hanging-wall veins and along strike.
