Project
The 100% owned Alamos silver project has a unique advantage as the only recent permitted silver discovery in Mexico an Environmental Impact Statement ("MIA”) for the development allowing for surface exploration and mining production activities, including the construction of drill pads, clean-up of preexisting roads, and the rehabilitation and reactivation of historical underground mine workings. Alamos hosts excellent infrastructure with the central area (Quintera-Promontorio vein zones) permitted from exploration through to production. The project lies 8 km west of the city of Alamos, 45 km northwest of Pan American's Alamo Dorado silver mine, and 15 km south of Cobre Del Mayo's Piedras Verdes copper mine. The project is 37,928 hectares.
Alamos hosts an initial inferred resource estimate of 55 million ounces silver equivalent grading 320 g/t silver equivalent (5.37 million tonnes containing 34.8 Moz silver, 35,640 ounces of gold, 51.0 Mlbs of copper, 115 Mlbs lead, and 238 Mlbs of zinc grading 202 g/t silver, 0.21 g/t gold, 0.43% copper, 0.97% lead, and 2.01% zinc). See Minaurum news release dated January 28, 2026 and Resource section above).
Minaurum has drilled 215 diamond core holes totaling 80,000 m on 19 of the 26 vein zones discovered at the Alamos silver project from 2017 - 2026.
A Phase II - 50,000 m resource expansion drill program is currently underway and targeting an updated resource in second half of 2026.
