Minaurum Gold Inc. (TSX-V: MGG) (OTCQX: MMRGF) is pleased to announce further results of its 2025 resource-definition drill program targeting the Promontorio, Travesia, and Europa vein zones at its Alamos Silver Project in Sonora, Mexico. Drilling continued to return numerous high-grade intersections including: (Table 1; Figures 1-4).

• 4.80 m of 287 g/t silver equivalent including 0.50 m of 1,029 g/t AgEq (Hole AL25-141)
• 1.10 m of 730 g/t AgEq (Hole AL25-142)
• 3.08 m of 523 g/t AgEq (Hole AL25-142)
• 1.40 m of 410 g/t AgEq (Hole AL25-148)

“Drilling continues to demonstrate the continuity of high-grade silver mineralization down dip and along strike,” stated Darrell Rader, President and CEO of Minaurum Gold. “At the Europa stacked vein system, hole AL25-142 vein intersected three intervals of significant mineralization, yielding targets for further drilling and resource development.”

2025 Resource-Definition Drilling

Minaurum has completed 35 holes on the Europa, Promontorio, and Travesia vein zones. Assays have been received for holes AL25-129 through AL25-149, with assays pending for the remainder (Figures 2 and 3).

Promontorio Vein Zone

Promontorio, along with the Europa vein zone, is one of the high-priority targets in which Minaurum will establish a maiden resource at Alamos. The 1 km-long Promontorio vein zone consists of multiple veins including the Veta Grande and Veta Las Guijas veins. Drilling to date at Promontorio and Promontorio Sur has intersected mineralization in epithermal vein-hosted cutting volcanic and intrusive rocks in addition to skarn/carbonate replacement (CRD) mineralization hosted by limestone in the footwall of the vein zones. Hole AL25-141 intersected 4.80 m of 287 g/t AgEq including 0.50 m of 1,029 g/t AgEq (771 g/t Ag, 0.49 g/t Au, 0.49% Cu, 2.09% Pb, and 4.29% Zn) and 0.55 m of 753 g/t AgEq (352 g/t Ag, 0.495 g/t Au, 0.79% Cu, 3.10% Pb, and 7.59% Zn). Hole AL25-147 drilled approximately 200 m to the southeast, intersected lead- and zinc-mineralized structures within the limestone in the down-dropped Promontorio Sur zone target, returning 0.55 m of 140 g/t AgEq and 0.25 m of 139 g/t AgEq, presenting CRD mineralization continuity with significant potential at depth (Table 1, Figure 2).

Travesia Vein Zone

The Travesia vein zone lies to the north of the Promontorio zone and in the same structural corridor (Figures 1 and 2). Further drilling is anticipated at Travesia to test potential for high-grade mineralization along strike and down dip.

Europa Vein Zone

Drilling has extended high-grade mineralization down-dip and along-strike (see Minaurum news release dated October 16, 2025). In the Nueva Europa vein zone, an interval of 1.10 m of 730 g/t AgEq with high grade silver of 606 g/t Ag including 0.55 m of 1,075 g/t Ag.

Hole AL25-142 returned 4.53 m of 396 g/t AgEq including 0.50 m of 1,271 g/t AgEq containing 983 g/t Ag (0.15 g/t Au, 0.85% Cu, 1.98% Pb, 5.28% Zn); and hole AL25-148 reported 1.40 m of 410 g/t AgEq. Along-strike and to the south, hole AL25-143 returned 0.90 m of 239 g/t AgEq and AL25-149 reported 0.70 m of 440 g/t AgEq also containing a high-grade interval of 300 g/t Ag. Drilling continues to step out along strike and down dip at Europa. (Table 1 and Figures 3 and 4).
