Minaurum Increases Phase 2 Resource Expansion Drill Program to 50,000 Meters at Alamos Silver Project

Minaurum Gold Inc. (TSXV: MGG,OTC:MMRGF) (OTCQX: MMRGF) ("Minaurum" or the "Company") is pleased to announce its plans to expand the Phase II resource-expansion drill program at the Alamos Silver Project in Sonora, Mexico from 25,000 metres to 50,000 metres, and in addition has issued a stock option grant.

"Driven by exceptional institutional interest in our ongoing financing, we are excited to announce plans to expand our Phase II resource-expansion drill program," said Darrell Rader, President and CEO. "Drilling continues to deliver high-grade silver intercepts, and the enhanced 50,000-metre Phase II program positions us to test a greater number of vein-zone targets and further grow the mineralized footprint, work that will support a major resource update planned for 2026. The resource update will build on the maiden resource estimate which the Company anticipates announcing in early 2026."

The expanded 50,000 m drill program in Phase II will continue to focus on infill and step-out results from the Phase I Drilling (see Minaurum news release dated November 27, 2025), with multiple rigs on site and 263 drill pads already permitted across the project. The program will include step-out holes at the Europa and Travesia silver shoots, as well as additional drilling at the historic Quintera and Minas Nuevas mines and the more recent discoveries at Promontorio Sur, Cotera, Pulpito, and San Jose vein zones (Figure 1).

Minaurum has identified 26 vein zones in an 11 km x 6 km region covering only one fifth of the Alamos Silver Project. Thirteen of the nineteen vein zones drilled returned high-grade silver intercepts. Only three of the thirteen discoveries will be included in the initial resource estimate.

Implementation of the planned expansion of the drill program remains subject to closing of the Company's ongoing financing. Please see Minaurum news release dated December 3, 2025, and associated offering document for additional details regarding the financing and anticipated use of proceeds.
