MINAURUM ANNOUNCES APPOINTMENTS OF OPERATIONS MANAGER AT THE ALAMOS SILVER PROJECT AND SENIOR MINE ENGINEER TO THE ADVISORY BOARD

Minaurum Silver Inc. has appointed Fernando Robles Noriega as operations manager of the production-permitted Alamos silver project in Sonora, Mexico, and has appointed Nicolas Figueroa Tapia to the company's advisory board.

"We are delighted to welcome Mr. Robles and Mr. Figueroa to Minaurum as we build the operational capabilities and expertise needed to advance Alamos through economic studies and development activities," stated Darrell Rader president and chief executive officer. "Their combined decades of hands-on Mexican underground mining and management experience will be invaluable as we evaluate future production centres, mining methods, and construction and infrastructure requirements. Ruben Molina, our senior project manager at Alamos, worked closely with Mr. Robles in developing SilverCrest's Las Chispas mine. Mr. Robles has already begun working with our exploration team to incorporate mine-development considerations into our ongoing exploration programs."

Mr. Robles brings 22 years of experience in Mexican mining and production operations, with extensive expertise in underground mining, mine planning and construction. Most notably, he served as mine superintendent at SilverCrest Metals' world-class Las Chispas silver-gold operation, where he worked alongside Ruben Molina, Minaurum's senior project manager at Alamos, and his resource modelling team. Las Chispas was subsequently acquired by Coeur Mining for $1.7-billion. Mr. Robles also held positions as underground mine manager at First Majestic Silver's San Dimas mine and Santa Elena mine.

As operations manager, Mr. Robles will work with the company's existing exploration team to incorporate exploration results into mine-development plans. His responsibilities will include evaluating potential production centres, advancing mine planning, underground mining methods, and assessing future construction and infrastructure requirements.

Minaurum is also pleased to welcome Mr. Figueroa Tapia to its advisory board. Mr. Figueroa is a mining engineer with more than 51 years of industry experience, including 40 years in senior mining operations with Industrias Penoles S.A. de C.V. His experience encompasses mining operations, mine planning and mine management. He will serve as an adviser to Mr. Robles and Minaurum's operational team as the company advances its mine development planning. Mr. Figueroa holds a BS in mining engineering and flotation plants from the University of Guanajuato, Mexico, and an MSc in sciences from Queen's University in Ontario, Canada.
