Minaurum Launches 25,000 Meter Phase 2 Resource Expansion Drill Program at Alamos Silver ProjectVancouver, British Columbia--(Newsfile Corp. - November 27, 2025) - Minaurum Gold Inc. (TSXV: MGG) (OTCQX: MMRGF) ("Minaurum") is pleased to announce the successful completion of its Phase I -10,000-meter (m) infill maiden resource drill program and the commencement of a Phase II - approximately 25,000 m resource expansion drill program at the Alamos Silver Project in Sonora, Mexico. "With Phase I of our resource-definition drilling now complete, we're excited to move toward a key milestone — the delivery of our inaugural resource estimate," stated Darrell Rader, President and CEO. "Once we receive assays from the Phase I program, we will complete the resource estimate. We're confident that the initial estimate will represent only a fraction of the project's full potential, as numerous high-priority discoveries remain outside the resource. The 25,000-metre Phase II drill program is specifically designed to test and expand both existing targets and additional zones toward a major resource update in 2026." Minaurum has identified 26 vein zones in an 11 km x 6 km region covering only one fifth of the Alamos project. Thirteen of the nineteen vein zones drilled returned high-grade silver intercepts demonstrating the abundant mineralization that occurs throughout the vein zones. Only three of the thirteen discoveries will be included in the initial resource estimate.Phase I Drilling targeted three high-grade vein zones — Promontorio, Europa, and Travesia — which will form the basis of the inaugural resource. Initial results have been released and continue to demonstrate continuity of high-grade silver mineralization (see Minaurum news release dated October 16, 2025). Once received, the remaining assays will be incorporated into the resource model in advance of the announcement of the resource estimate.Phase II Drilling will build on the results of phase I with a planned 25,000 meters of drilling. The program will include step-out holes at the Europa and Travesia silver shoots, as well as additional drilling at the historic Quintera and Minas Nuevas mines and the more recent discoveries at Promontorio Sur, Cotera, Pulpito, and San Jose vein zones. Minaurum is well positioned to advance this next phase, with 263 drill pads already permitted across the project.Figure 1.

Average vein thickness is 3.00 m with a grade of 454 g/t AgEq* (358 g/t Ag, 0.5% Cu, 0.6% Pb, 1.2% Zn). Drill targeting will focus on the total strike length and open to depth drilling through multiple hanging wall veins and splays (Figure 2). Figure 2.

Average vein thickness is 5.40 m with a grade of 338 g/t AgEq* (170 g/t Ag, 0.4% Cu, 1.0% Pb, 2.0% Zn). Drilling at Travesia which is on the hanging wall of the Quintera vein system, will target a high prospectivity zone on stacked vein system as well as the parallel striking historic Quintera mine. Promontorio Sur is the structurally off-set section of the trend with a strike length of 1 km. Figure 3. Travesia, Quintera and Promontorio vein zone longitudinal section.

Drill targeting will focus on the 1.2 km strike length at Minas Nuevas at the Zambona and Purisima veins, targeting secondary veins that have reported grades through historical drilling. Testing at San Jose will focus on a 1.5 km long section where previous drilling intercepted a wide vein system with secondary veins and splays. Drilling will also test the stacked veins at the Pulpito/Cotera vein zone.Figure 4.
