(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - October 16, 2025) - Minaurum Gold Inc. (TSXV: MGG) (OTCQX: MMRGF) ("Minaurum") is pleased to announce the initial results of its 2025 resource-definition drill program targeting the Promontorio, Europa, and Travesia vein zones at its Alamos Silver Project ("Alamos") in Sonora, Mexico. These vein zones returned numerous high-grade intersections including: (Table 1; Figures 1-3).

• 5.85 m of 476 g/t silver equivalent ("AgEq") including 1.80 m of 1,339 g/t AgEq (Hole AL25-135)
• 21.45 m of 220 g/t AgEq including 1.00 m of 497 g/t AgEq and 1.20 m of 1,377 g/t AgEq (Hole AL25-138)
• 2.40 m of 499 g/t AgEq including 0.85 m of 981 g/t AgEq (Hole AL25-139)
• 1.75 m of 845 g/t AgEq including 0.50 m of 1,366 g/t AgEq (Hole AL25-139)

"Drilling at both Europa and Promontorio continues to confirm the continuation of strong, wide zones of high-grade silver mineralization at depth and along strike," stated Darrell Rader, President and CEO of Minaurum Gold. "At Promontorio, drilling intersected over 21 metres of robust carbonate replacement-style lead-zinc-silver mineralization. These drill results along with those pending assays, will be incorporated into and will complete the data set for our upcoming maiden resource estimate."

2025 Resource-Definition Drilling

Minaurum has to date completed 28 holes on the Europa, Promontorio, and Travesia vein zones. Assays have been received for holes AL25-129 through AL25-140 with assays pending for the remainder (Figure 1).

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 show significant skarn/carbonate replacement (CRD) mineralization hosted by limestone in the footwall of the vein zones. Hole AL25-138 intersected a significant wide zone of skarn/CRD lead- and zinc-sulfide mineralization including silver and gold values: 21.45 m of 220 g/t AgEq including 1.00 m of 497 g/t AgEq and 1.20 m of 1,377 g/t AgEq (440 g/t Ag, 1.499 g/t Au, 9.089% Pb, 18.783% Zn) (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

Europa drilling in 2025 has extended know mineralization at Europa, most notably down-dip in holes AL25-135 and AL25-137 (Table 1 and Figure 3). Holes AL25-131, AL25-134, and AL25-139 filled in gaps between known vein intersections. Assays are pending for several more holes at Europa and drilling continues to step out along strike and down dip. Significant mineralization was intersected in Hole AL25-135 which returned 5.85 m of 476 g/t AgEq including 0.70 m of 2,601 g/t AgEq (2,180 g/t Ag); and hole AL25-139 returned 2.40 m of 499 g/t AgEq including 0.50 m of 1,366 g/t AgEq (851 g/t Ag).
