Minaurum Drills High-Grade Silver at Alamos including: 21.45 m of 220 g/t AgEq, 5.85 m of 476 g/t AgEq and 1.75 m of 845 g/t AgEq
FOR RELEASE: October 16, 2025 · TRADING SYMBOL: TSX-V MGG | OTCQX MMRGF
Including highlight intercepts of 21.45 m @ 220 g/t AgEq, 5.85 m @ 476 g/t AgEq, and 1.75 m @ 845 g/t AgEq from the Promontorio, Europa, and Travesia vein zones at the 100%-owned Alamos Silver Project, Sonora, Mexico.
Minaurum Gold Inc. (“Minaurum”) (TSXV: MGG) (OTCQX: MMRGF) 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 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)
“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 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. Weight-averaged silver-equivalent grades are based on October 1 2025 Long-term CIBC Global Mining Group Analyst Consensus Commodity Price Forecast: Ag $29.73 / oz, Au $2,646 / oz, Cu $4.34 / lb, Pb $0.92 / lb, Zn $1.21 / lb.
Promontorio Vein Zone
Hole AL25-138 intersected a significant wide zone of skarn/CRD mineralization: 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.
