Initial Resource Estimate At Alamos Silver Project

VANCOUVER – Minaurum Silver Inc. announced the completion of an Inferred Mineral Resource Estimate at its Alamos Silver Project located in Sonora, Mexico. High Grade Inferred Mineral Resource: Resource Estimate of 5.37 million tonnes (Mt) grading 202 g/t silver, 0.21 g/t gold, 0.43% copper, 0.97% lead, and 2.01% zinc, or 320 g/t silver equivalent (AgEq) and containing 34.8 million ounces (Moz) of silver; 35,640 ounces of gold; 51.0 million pounds of copper; 115 million pounds of lead; and 238 million pounds of zinc; or 55.2 Moz AgEq. Calculations include smelter and processing deductions typically associated with more advanced resource estimates. Sensitivity analysis further indicates that the resource remains resilient at higher cut-off grades than 150 g/t AgEq, emphasizing the high-grade nature of the mineralization. The Resource Estimate encompasses portions of the Promontorio, Travesia, and Europa vein zones-three of the twenty-six vein zones identified at Alamos. The resource is open along strike and at depth, offering significant potential for expansion through the ongoing Phase II 50,000 m resource expansion drill program.
The Resource Estimate, completed by Independent Mining Consultants, Inc., is based on a total database of 104 drill holes, totaling 35,888.15 metres and 10,194 samples. The Resource Estimate is classified as an Inferred Mineral Resource in accordance with CIM Definition Standards, with an effective date of January 8, 2026.
“Our inferred resource estimate of 55 million ounces of AgEq, defined across portions of just three of the 26 identified vein zones at Alamos, represents a major milestone for Minaurum,” said, Darrell Rader, President and CEO. “The estimate establishes Alamos as a high-grade silver district with a rare combination of grade and width, with each of the vein zones included remaining open for expansion. Our next step is to aggressively grow the resource through the ongoing Phase II 50,000-metre resource expansion drilling program. I would like to thank the entire Minaurum team, along with our contractors and local communities, for their contributions to this achievement.”
