Minaurum Silver Inc. (TSXV: MGG) announced the discovery of the Africa vein zone, a previously unrecognised blind silver vein at its Alamos Silver Project in Sonora, Mexico, returning 669 g/t silver-equivalent (AgEq) over 2.05 metres. The company also reported multiple high-grade results from its ongoing Phase II, 50,000-metre resource-expansion drilling program at the Europa Sur, Quintera, San Jose, and Promontorio Sur vein zones. The disclosure suggests the programme is yielding broader mineralisation potential beyond the project's known surface-exposed veins, a development investors in junior silver explorers may be watching closely.

Key Points

  • Minaurum Silver Inc. (TSXV: MGG | OTCQX: MMRGF) announced new drill results from the Alamos Silver Project, Sonora, Mexico
  • The blind Africa vein zone was discovered approximately 50 metres in the footwall of the Europa Sur vein, returning 669 g/t AgEq over 2.05 metres
  • Europa Sur returned 367 g/t AgEq over 2.65 metres; Quintera returned 462 g/t AgEq over 1.50 metres; an updated mineral resource estimate is expected in the second half of 2026
  • Investors may be watching progress of the Phase II 50,000-metre drill program and the timing of the updated resource estimate

Africa Vein Discovery Signals Blind Mineralisation Potential Across Alamos

The Africa vein zone was intersected in holes AL26-257, AL26-268, and AL26-270, lying about 50 metres west of the Europa Sur vein in its footwall. Company geologists identified significant alteration in the footwall and extended hole AL26-257, which returned 1.30 metres of 592 g/t AgEq. Hole AL26-268 followed with 2.05 metres of 669 g/t AgEq, including 270 g/t Ag, 0.87 g/t Au, 1.55% Cu, 2.80% Pb, and 5.62% Zn. The release states the Africa vein remains open along strike, with an earlier historical intersection approximately 400 metres to the north also located in the Europa Sur footwall.

Europa Sur and Quintera Zones Deliver Multiple High-Grade Intercepts

Resource-expansion drilling at Europa Sur returned standout results including 0.60 metres of 1,140 g/t AgEq (hole AL26-261) and 2.65 metres of 367 g/t AgEq (hole AL26-266), with the latter containing a sub-interval of 1.35 metres grading 596 g/t AgEq. Europa Sur is not included in the project's existing inferred initial resource. At the Quintera vein zone, hole AL26-259 returned 3.20 metres of 253 g/t AgEq, including 1.50 metres of 462 g/t AgEq. The release states the Quintera zone is expected to contribute to the upcoming updated mineral resource estimate.

Promontorio Sur and San Jose Vein Zones Add to Alamos Drill Campaign

Drilling at Promontorio Sur returned 3.95 metres of 160 g/t AgEq in hole AL26-263, including 1.20 metres of 301 g/t AgEq, while hole AL26-265 reported a high-grade interval of 0.40 metres at 691 g/t AgEq. The release states assays remain pending for additional Promontorio Sur holes. At San Jose, hole AL26-267 intersected 0.30 metres of 782 g/t AgEq grading 660 g/t Ag, with the San Jose zone also expected to contribute to the updated resource estimate. All results form part of the Phase II, 50,000-metre program currently underway at Alamos.
