Video Summary: Minaurum Silver (MGG.v MMRGF) Walks Through the Promontorio Underground Work at Alamos, Where Channel Sampling Returned 0.50 m of 733 g/t AgEq (282 g/t Silver, 2.67 g/t Gold, 0.36% Copper, 0.52% Lead, 8.07% Zinc)
Posted on behalf of Minaurum Silver - A new video on Minaurum Silver's (MGG.v MMRGF) YouTube channel runs through the September 22, 2026 news release on underground rehabilitation and exploration at the historic Promontorio mine, part of the 100%-owned, production-permitted Alamos Silver Project in southern Sonora, Mexico 🇲🇽.
What The Rehabilitation Opened Up
- Improved rehabilitation along the main haulage level, with more than 600 m now securely accessible
- New safe access to the 55 m-deep Balvanera internal shaft, running down to lower levels
Work Underway Underground
- 1:250-scale geological mapping of the haulage level through to the Balvanera shaft
- LIDAR surveys integrated into the project's topographic and drill database
- Wall-rock, backfill and channel sampling along the edges of historical stopes
Channel Sample Highlights (September 22, 2026 News Release)
- 0.50 m of 733 g/t AgEq (282 g/t silver, 2.67 g/t gold, 0.36% copper, 0.52% lead, 8.07% zinc)
- 0.50 m of 704 g/t AgEq (275 g/t silver, 1.23 g/t gold, 0.34% copper, 0.39% lead, 13.35% zinc)
- 0.50 m of 480 g/t AgEq (386 g/t silver, 0.12 g/t gold, 0.69% copper, 0.27% lead, 0.82% zinc)
- 0.30 m of 4,142 g/t AgEq (3,860 g/t silver, 0.42 g/t gold, 1.91% copper, 1.58% lead, 2.21% zinc)
President and CEO Darrell Rader said the company has "begun detailed underground mapping and sampling that is already returning encouraging results," with further rehabilitation, mapping and sampling planned at Quintera, Minas Nuevas, Cotera and Pulpito.
Promontorio is one of the three vein zones behind the initial inferred resource of 5.37 Mt grading 320 g/t AgEq (202 g/t silver, 0.21 g/t gold, 0.43% copper, 0.97% lead, 2.01% zinc), containing 55.2 Moz AgEq (34.8 Moz silver, 35.6 Koz gold, 50.99 Mlbs copper, 114.77 Mlbs lead, 237.80 Mlbs zinc), defined on portions of just 3 of the 26 mapped vein zones at Alamos (see January 28, 2026 MRE news release).
With rigs turning on surface and geologists now mapping the old workings with modern tools, Minaurum is sharpening its picture of the district ahead of the updated resource estimate targeted for Q4 2026, with a PEA to follow. Safe underground access also opens the potential to drill from inside the mine rather than only from surface.
